Thus, the three-phase monitoringrelays of the CM range, according to the individual requirements,m onitor the phase voltages, phase sequence, phase unbalance,phase failure and the neutral:Monitoring for over- and undervoltageAll electric devices can be damaged when operated conti-nuously at voltages over or under their rated values.An overvoltage could potentially cause heating within thedevice. If the temperature is unduly high, component partsand thus whole devices or installations may fail or may bedestroyed. Undervoltages involve the risk that the switchingelements reach an undefi ned region. In this case, parts of theinstallation still function, but not others. This misoperation canresult in damage of the product or installation. In the worstcase, wrong voltages may even cause harm to the operatingpersonnel.Phase unbalance monitoringIf the supply by the three-phase system is unbalanced dueto uneven distribution of the load, the motor will c onverta part of the energy into reactive power. This energy getslost u nexploited; also the motor is exposed to h ighert hermal strain. Other thermal protection devices fail to de-tect c ontinuing unbalances which can lead to damageor d estruction of the motor. The CM range three-phasem onitoring relays with phase unbalance monitoring canr eliably detect this critical situation.Phase failure detectionIn case of a phase loss, undefi ned states of the i nstallationare likely to occur. E.g. the startup process of motors isd isturbed. All three-phase monitoring relays of the ABB CMrange detect a phase loss as soon as the voltage of onep hase drops below 60 % of its nominal value.Phase sequence monitoringAn incorrect phase sequence applied at start-up or a changeof the phase sequence during operation will cause a 3-pha-se motor to run with reverse rotation. Certain motors whenoperated in the reverse direction will cause severe damage toconnected loads such as pumps, screw compressors and fans.Especially for non-fi xed or portable equipment, such as construc-tion machinery, phase sequence detection prior to the start-upprocess is highly recommended. ABB offers three-phase monitorswith selectable phase sequence monitoring. This provides thecapability of ignoring phase sequence conditions for applications,such as motors with forward and reverse rotation, where the pha-se sequence is unimportant.Interrupted neutralUnder normal conditions, individual phase voltages are equal andthe load causes the individual phase currents to vary. Systemsthat have neutral conductors accommodate this variation by acompensating current fl ow through the neutral conductor. If theneutral conductor breaks, the compensating current can no lon-ger fl ow. As a result, the voltage is divided asymmetrically on theindividual phases. This means that over- and undervoltages areproduced in the individual phases and these can damage or evendestroy the connected consumers. ABB offers three-phase mo-nitoring relays that monitor the neutral conductor for interruptedneutral. The interruption of the neutral is detected by means ofphase unbalance monitoring.Three-ph a se m o n i t o ri ngN E WG E N ER A T I ON2008.10.0152C D C 252 086 F 0b 072C D C 252 087 F 0b 07Three-phase monitors CM rangeAutomatic phase sequence correction The new generation of ABB three-phase monitoring relays offers devices with automatic phase sequence correction. If phase sequence monitoring and phase sequence correction are activa-ted, and in conjunction with a reversing contactor combination, it is ensured that for any non-fi xed or portable equipment, e.g. construction machinery, the correct phase sequence is applied to the input terminals of the load.Control circuit diagram(K1 = CM-MPS.x3 or CM-MPN.x2)Power circuit diagramAdjustment possibilities on the front of the unit in the example of CM-MPS.43Adjustment of the threshold for overvoltage Adjustment of the threshold for undervoltage Adjustment of the threshold for phase unbalance1)Adjustment of the tripping delay t VDIP switches for function selection: (1) Timing function ON = A ON-delay OFF = B OFF-delay(2) Phase sequence monitoring ON = deactivatedOFF = activated(3) Operating principle of the output contacts ON = i 2x1 c/o (SPDT) contact 1)OFF = j 1x2 c/o (SPDT) contacts (4) Automatic phase sequence correction ON = activatedOFF = deactivated1)for separate signalling of over- and undervoltageN E WN E WN E WN E W62C D C 253 100 F 00042C D C 253 090 F 0004Selection guide and order referencesCM-E - Economy1SVR 550 881 R94001SVR 550 882 R95001SVR 550 870 R94001SVR 550 871 R95001SVR 550 824 R91001SVR 430 824 R9300A ON-delay,B OFF-delayCM-S2C D C 253 089 F 00042C D C 253 260 F 0005T h r e e -p ha s e m o n i t o r ingN E W GE N E R A T I O N2008.10.011SVR 630 784 R33001SVR 630 794 R13001SVR 630 794 R33001SVR 630 774 R13001SVR 630 774 R33001SVR 630 885 R13001SVR 630 885 R33001SVR 630 884 R13001SVR 630 884 R330- Single-functionalCM-S - Multifunctional7/8CM-N - MultifunctionalAccessories for CM-S devices1SVR 630 885 R43001SVR 630 884 R43001SVR 650 487 R83001SVR 650 488 R83001SVR 650 489 R83001)Operating mode 1x2 or 2x1 c/o (SPDT) contact can be selected. 2x1 c/o (SPDT) contact for separate signalling of over- and undervoltage.Selection guide and order references92CDC6639F4Kr-SaegeNominal condition: Three-phase motor with monitoring relay CM-MPS.xx in fulloperationFault: Three-phase motor with line regeneration and a monitoring relayCM-MPS.xx prior to tripping due to a phase failureSwitch-off in case of failure: Three-phase motor with phase loss in L2 afterm onitoring relay CM-MPS.xx has trippedIndication of a phase loss on a running three-phasemotor (with reverse feeding) by the phase unbalancemonitoring of the three-phase monitor CM-MPS.xx:Nominal conditionThe motor is only turned-on, when the CM-MPS.xxdetects the correct phase sequence L1-L2-L3 andwhen all voltages are within the preset voltage rangeUmin/Umax: I.e. no over-/undervoltage, no phase failure,and no phase unbalance is indicated.FaultPhase loss (in this example phase L2) caused by ablown fuse and voltage loss caused by generatore ffect of the motor.Voltage at the point can reach up to 95% ofthe original voltage, depending on the motor typeused, the motor load and other parameters.The phase loss on a running motor can only bereliably detected by phase unbalance monitoring(e.g. with the CM-MPS.xx).In operation, the CM-MPS.xx switches off the runningmotor, when the difference between one phase andthe nominal voltage exceeds the preselected valueͬU.

ABB电机保护断路器
电机保护断路器是电动机在起动、运行和运行中分断中不可缺或的保护电器之一。
用于电动机保护,当电动机发生过载、短路、欠电压等故障时,能自动切断电路予以保护。
ABB 电机保护断路器凭借其高质量的特点在市场上备受青睐。
在此为大家介绍其基本特性参数。
(1)额定工作电压Ue额定工作电压是指断路器的标称电压,在规定的正常使用和性能条件下,能够连续运行的电压。
我国规定在220kV及以下电压等级,系统额定电压的1.15倍即为工作电压上限;330kV 及以上电压等级是以额定电压的1.1倍作为工作电压上限。
断路器能在系统工作电压上限下保持绝缘,并能按规定的条件进行关合与开断。
(2)额定电流In额定电流是指在环境温度为40℃以下,脱扣器能长期通过的电流。
对带可调式脱扣器的断路器来说,则为脱扣器可长期通过的电流上限。
当使用在环境温度超过40℃,但不高于60℃时,允许降低负荷长期工作。

ABB 新式紧凑型电缆保护设备说明书
Compact and reliable switching Smaller, more efficient and simpler gas-insulated switchgearHANS-DIETER SCHlEMPER – Gas-insulated switchgear (GIS) operates invisibly – no movement, just a faint hum, betrays the flow of bulk AC power. At first sight uncomplicated-look-ing, a closer examination reveals the complexity in the variety of configurations, engineering investment and installation effort found in a typical GIS installation. Now, however, ABB’s new compact GIS switchgear makes everything much simpler. Even at 420 kV ratings, the switch-gear is assembled as a complete bay in the factory, includ-ing wiring and testing. Installation is fast and easy: Bays move on wheels to their final destination and they can be assembled in a day. The compact dimensions leave more space for access, fit in even smaller buildings and save on resources such as SF6and metals.11Compact and reliable switching12ABB review special reportThe first GIS was installed in 1965 and used sulfur hexafluoride gas (SF 6) as in-sulation. Today, GIS switchgear is avail-able from 52 to 1,200 kV rated voltage [1]. C urrent trends and needs in GIS i nclude:− Less complex, more standardized designs that inherently improve reliability and ease project engineer-ing, production, installation and maintenance. Purchase and use of GIS should become simpler, delivery times shorter and service life longer. − Smaller dimensions that save resourc-es, provide more convenient access to the equipment and enable installa-tion in smaller buildings or containers. − Digital controllers and electronicmeasuring equipment that provide comprehensive monitoring, supervi-sion and control functions. − Higher continuous current and short-circuit current ratings.− Less use of SF 6 and reduction of SF 6emissions.Much electrical switchgear is found out in the open, so the electrical breakdown prop-erties of air have to be takeninto account in its design. As a result, switchgear installations can take up substantial real estate. Where space is costly or limited, or where the environ-ment is challenging, GIS is an ideal alter-native. In GIS equipment, switching is done inside a gas-filled sealed vessel. The gas has much better insulation properties than air, so equipment can be made a lot smaller. Substations located underground in cities, inside hydropow-er dams, in high-value real-estate areas or in containers could not be realized without GIS technology.GIS is suitable for use in harsh environ-ments such as deserts, high-altitude lo-cations or offshore oil platforms. Its lownoise levels and low electromagneticemissions allow operation in residentialareas or in sensitive industrial plants.GIS also improves the grid’s efficiency as it enables power to be transmittedat higher voltages closer to the loadcenters in cities.ABB’s new GIS products for 72.5 kV, 245 kV and 420 kV, launched in 2010, 2011 and 2012 respectively, address these trends. The entire family is built on common design principles and the family members share many common components.Compact and efficientThe new products mark a significanta dvance in footprint reduction – be it in terms of dimensions or use of raw mate-rial and SF 6.The new portfolio is based on advanced circuit breakers with small dimensions and small drives. The ELK-14 compact, 245 kV GIS features an advanced dou-ble-motion Auto-Puffer TM (self-blast) cir-cuit breaker. A single pole requires less than 900 J of stored energy to interrupt a short-circuit current of 50 kA. The ELK-14 compact has 43 percent less volume and weighs 2 tons less than the prede-cessor product ➔1. The result is a com-pact bay that fits into containers that are used for shipment or even as a perma-nent housing.The ELK-3 compact, 420 kV GIS fea-tures a new, single-interrupter puffer breaker with an excellent two-cycle per-formance at 63 kA/60 Hz and plenty of reserve for short-line faults and other duties. The ELK-3 compact circuit breaker uses just one interrupter where two interrupters in series and a larger drive were needed in the past. The sav-ings in dimensions and weight are sig-nificant ➔2.Title pictureABB’s new GIS products greatly speed up and simplify installation. The GIS ELK-3 compact product is shown here.GIS is suitable for harsh environments such as deserts, high-altitude loca-tions or offshore platforms.1 Elk-14 compact, 245 kV compared with its predecessor13Compact and reliable switchingSimplicityABB’s new GIS consists of a set of high-ly-standardized building blocks that can be configured to the specific user r equirements at a very late stage of the production process. This reducesdelivery time. Even at 420 kV, the GIS is equipped with integrated local control panels mounted directly on the steel sup-port carrying the bay. Instead of wiring the bay on-site to a distantcontrol panel, all the cabling is done at the factory in a controlled environment with automated testing facilities. Any wiring mistakes are corrected before the bay leaves the factory.Installation time nearly halvedThe new GIS designs enable complete wired bays to be shipped in containers or on flat racks. A typical 420 kV substa-tion now requires only 44 shipping units and 53 coupling steps compared with the 80 shipping units and 74 coupling steps of the predecessor product.On site, 420 kV bays are wheeled from the unloading platform into the building to their final destination. After leveling, coupling adjacent bays and connecting them to the substation control systems takes only a few hours. Before leaving the factory, bays are prefilled with SF 6 at a transport pressure slightly above1bar, which significantly reduces time and effort for on-site gas handling. Low-pressure aluminum die casting and 3-D finite-element stress calculations enable the design of enclosures with complex shapes that still meet pressur-ized vessel standards at high safety margins. The result is “skinny” enclo-sures that minimize the enclosed vol-ume and, thus, the SF 6 content. A good example is the ENK GIS type for 72.5 kV rated voltage that uses a mere 27 kg SF 6 per bay (for a typical double busbar bay with cable connections) – less than half that used by traditional designs. Or the ELK-14, which uses 115 kg SF 6, 32 kg less than the predecessor prod-uct.Best of both worlds Traditional GIS often uses single-phase enclosed designs for 245 kV. Although they would reduce complexity, three-phase enclosed GIS components for 245 kV are large and difficult to design. ELK-14 compact is innovative: All com-ponents are three-phase-enclosed but, instead of three-phase partition insula-tors, as used at 145 kV, it uses single-phase insulators. Together with skinny enclosures, ELK-14 is somewhere in between traditional single-phase and three-phase design and combines the best of the two approaches.GIS improves the grid’se fficiency as it enables power to be transmitted at higher voltages closer to the load centers in cities.The entire family is built on common design principles and the family members share many common components.2 Elk-3 compact, 420 kV compared with its predecessor14ABB review special reportIn all, installation time is cut by some 40 percent.Easy access operation Although there is little maintenancer equired, all relevant parts, such as drives, view ports, gas density sensors, gas filling valves and terminal blocks are easily accessible – thus shortening maintenance or repair times.A unique feature is that the drives and position indicators for disconnectors and grounding switches are locatedu nderneath the local control panel ➔3. The user can access the drives from the operator’s aisle for emergency manual operation with a hand crank or to lock them with a padlock. Access laddersor scaffolding is no longer required.B esides, drives are plug-in units and they can be easily pulled out of the c abinet for inspection or maintenance.C onvenient access to viewports, gas valves and monitors is provided by plat-forms and catwalks. These are an inte-gral part of the GIS and no longerr equire custom designs.Digital sensors and smart switchgearToday’s practice of measuring basicp arameters using inductive current transformers (C Ts) and voltage trans-formers (VTs) has parallels with the changeover from vinyl records to C Ds: Gone was the distortion created by ana-log reproduction as C Ds and optical links ensured low-cost, interference-free audio reproduction every time.C urrent and voltage measurement in substations is undergoing a similartransformation. The old problems caused by transient performance and saturation of C Ts, over/under-burden-ing, cable length or cross section and troublesome relay input impedance are being banished by the adoption of elec-tronic precision transducers for current(ECTs) and voltage (EVTs). These comewith digital interfaces and connect as easily as a C D player to protection r elays with digital inputs. Their stability, dynamic range and precision are out-standing – a single EC T provides both class 0.2 metering data and precision current data in the kiloampere range. Consequently, most of ABB’s GIS equip-ment is now available with compact EC Ts and EVTs employing Rogowski coils and capacitive voltage transducers[2]➔4. They connect to any relay with anIEC 61850-9-2-compatible digital opti-cal interface, eg, ABB’s Relion series. Although not yet commonly used, ECTsand EVTs, together with intelligent bay controllers, such as ABB’s REC670, and protection devices, form the basis of a digital control panel. Replacing bulky hardwired controls and a sizeable bind-er of schematics, a digital control panel has a network interface based on IEC 61850 data models and communi-cation protocols. The GIS bay is deliv-ered with an electronic capability de-scription in XML – ready to be loaded,The GIS consists of a set of highly-standardized build-ing blocks that can be configured to the specific user requirements at a very late stage ofproduction.3 Frontal access to drives (Elk-14 compact) 4Combined ECT/EVT for 420kV15Compact and reliable switching grate renewable energy sources andf ocuses on providing Denmark with green energy. Energinet.dk selected GIS technology for new 420 kV substationsto reduce space consumption and visu-al impact. A project currently underway is the con-struction of a new 400kV connection between Kassø, near Aabenraa, and Tjele. A 400 kV double-circuit line, in-stalled on tubular towers designed to blend into the landscape, will reinforce and renew Jut-land’s grid. The line will replace the approximately 45-year-old sin-gle-circuit line op-erating on the section today. The project received funding from theEuropean Union’s trans-European ener-gy networks program. Part of the project is Revsing substa-tion. It forms a node with other 420 kV connections along the line. Energinet.dk selected the ELK-3 compact based on a comprehensive list of selection criteria that reflect the company’s demands.Decisive features were the low SF 6 gas content, the compactness (resulting in a small building, crane and basement) and the short installation time.browsed and integrated into the substa-tion automation system ➔5.As part of the new portfolio, ABB’s engi-neers have developed a comprehensive but simple-to-operate gas monitoring sys-tem called modular switchgear monitoring (MSM) that can be added to conventional controls or digital control panels ➔6.MSM’s main task is to detect even small leaks at rates as low as 0.5 percent per year with a set of linear prediction filters. The filters are tuned so as to distinguish leaks from natural density variations stemming from inhomogeneous temper-ature distributions in gas compart-ments. Unlike traditional gas density monitors, which would flag an alarm first when 5 to 10 percent of the SF 6 had already leaked, MSM alerts the operator when as little as 1 to 2 percent of the gas has escaped.Case study: Revsing substationEnerginet.dk owns and operates the transmission grid and the natural gassystem in Denmark. The company builds intelligent infrastructure to inte-Revsing substation will be commis-sioned in 2013. The new line is sched-uled to commence operation in 2014.Though established more than 40 years ago, GIS technology is still rapidly de-veloping. It continues to serve as a key element in growing grids. The installa-tion of GIS is becoming faster and the operation easier. C ompact designs useless raw materials and SF 6.

关于ABB保护器(CM-MPS)说明
关于ABB断相与相序保护器(CM-MPS.41)动作的分析报告
大功率三相异步电动机的启动对电网的冲击,主要表现在有限的配电容量下,电流大幅增加,配电系统阻抗上的压降增大,导致负载端电压下降,轻则导致电动机不能正常启动,重则危及所在配电网的正常运行。
为避免电动机在较低的电压下工作,一般的大功率电机都设有电压保护(包括过压、欠压、逆缺相、不平衡等保护功能)。
1 CM-MPS.41断相与相序保护器
在目前的离心机启动柜中(星三角启动柜及降压启动柜),使用的是ABB断相与相序保护器(CM-MPS.41如图1),主要用于监视三相电源系统的参数,如相序、缺相、过欠压和不平衡。
护;对于有转向规定的电动机,则需将DIP拨码开关2至于OFF位置,开启相序保护功能。
