This mechanical interlock allows any two breakers to close while holding the third in the open (tripped) position. A lever assembly is mounted on each breaker that interfaces with the pole shaft and the tripper bar. The lever assemblies are interconnected with cables. Cable can be used for any orientationof the breakers, and are available in 5, 6, 8, and 10-foot lengths (1,5; 1,8; 2,4; and 3,0 m). Individual cable kits are ordered separately.Required tools• 10 mm socket and 1/4-inch drive socket• 10 mm open end wrench• 11/16-inch open end wrench• 3/8-inch open end wrench (2)• 0.5 mm feeler gauge• 4 mm Allen wrench• Drive extension• PliersKit parts identificationRefer to Figure 1 and Figure 2 for visual identification of the parts listed below:Kit 1 (2A11857G05, shown in Figure 1): Interlock Assembly Kit(A) M6 x 12 mm hex bolt (nine)(B) M6 x 25 mm flat-head screw (three)(C) M6 lock washer (nine)(D) M6 x 16 mm hex bolt (six)(E) Drive arm (three)(F) Interlock assembly (three)(G) Grease tube (one)Kit 2 (2A11858G01-G04, shown in Figure 2): Interconnecting Kit (includes cables)(H) Cable bracket (two)(I) M6 x 10 mm thread-forming screws (four) (J) Cable assembly (two) - in 5-, 6-, 8-, or 10-foot lengths (1,5; 1,8; 2,4; or 3,0 m)Note: Three sets of kit 2A11858G01, G02, G03, or G04 (six cables total) are required for this installation.Note: Part (D) is not used for this installation.2Instructional Leaflet IL2C12863H08Effective March 2012Three-way cable interlock kit for Magnum drawout circuit breakers(Type 32 interlock)EATON CORPORATION Figure 1. (A)(G)(E)(D)(C)(B)(F)Contents of Kit 1Figure 2. (I)(K)(J)Contents of Kit 2Section 2: Installation of three-waycable interlockProceed with the following 12 steps:Step 1: Remove the front cover by unscrewing the hex-head captive bolts (four for three-pole, six for four-pole) that join the cover to the breaker housing using a 10 mm 1/4-inch drive socket. Then hold the charge handle down approximately 45 degrees to pull off the cover.Step 2: Remove the knockout (a U-shaped tab) from the right side of the front cover using pliers. Carefully file any excess material from the broken edge.Figure 4. Step 2Step 3: Install drive arm (E ) to the right end of the pole shaft using an M6 x 25 mm flat-head screw (B ) and 4 mm Allen wrench. The drive arm should be oriented as shown. Torque to 65-85 in-lbs (7,3-9,6 Nm).3Instructional Leaflet IL2C12863H08Effective March 2012Three-way cable interlock kit for Magnum drawout circuit breakers (Type 32 interlock)EATON CORPORATION Step 4: Reinstall front cover (removed in Step 1). Perform Steps 1 to 4 for each breaker.Step 5: Fasten the interlock assembly (F ) to the drawout cassette’s right-side sheet as shown, using three M6 x 12 mm hex bolts (A ) and lock washers (C ). Torque to 40–50 in-lbs (4,5–5,6 Nm).Step 6: Fasten the cable bracket (H ) to the drawout cassette’s right-side sheet (below the interlock assembly installed in Step 5) as shown, using two M6 x 10 mm thread-forming screws (I ). Torque to 65 – 85 in-lbs (7,3 – 9,6 Nm). Perform Steps 5 to 6 for each breaker.Figure 7. Step 6Step 7:Check the functionality of the interlock assemblies by performing the following two checks. Refer toFigure 8:Check 1:• Fully insert the breaker into its cassette to the CONNECTED position.•Make sure the drive arm (E ) and the interlock assembly’s inner trip arm pass clearance. The teardrop-shaped follower arm of the interlock assembly should engage with the pin on the drive arm. The inner trip arm of the interlock assembly should engage with the tripper bar of the breaker.•Perform this check for each breakerCheck 2:• With the breaker OPEN and CONNECTED, observe the position of the DRIVE (LOWER) LEVER. There should be a 0 – 4 mm gap between the lower right-hand corner of the drive lever and the mounting bracket flange (see Figure 8 Breaker OPEN).•Now CHARGE and CLOSE the breaker. The drive lever should rotate approximately 60 degrees counterclockwise. Thereshould be a 1 – 7 mm gap between the lower left-hand corner of the lever and the interlock assembly flange (see Figure 8 Breaker CLOSED).•If either of these gaps is out of specification, DO NOTCONTINUE THE INSTALLATION. Consult Eaton for additional instructions. To reach an EatonCare representative, call (877) 386-2273.•Perform this check for each breaker.Figure 8. Step 7Step 8: This step will prepare the cables before they are attached to the interlock assembly. Check to be sure that all cables move freely in their cable housing. Each cable should have a long rod end and a short rod end. To perform the cable prep:1. Remove the upper lock nut and spacer tube from both rod ends.2. Remove the compression spring from the short rod.3. Two loose nuts should be positioned on the threads of each rod. Shoulder the lower nut against the rod threads until the nut stops. Using two 3/8” wrenches, tighten the upper nut against the lower nut (see Figure 10).Repeat the above process on both long and short rods on any given cable.4Instructional Leaflet IL2C12863H08Effective March 2012Three-way cable interlock kit for Magnum drawout circuit breakers(Type 32 interlock)EATON CORPORATION Figure 9. Step 8 - Cable AssemblyFigure 10. Step 8 - Cable PrepStep 9: This step describes how to route the cables between breakers. Each breaker should be in the OPEN and DISCHARGED position. When routing cables, adhere to the following recommendations:• 4 inch (102 mm) minimum allowable cable housing bend radius and minimal number of total bends•Use plastic wire ties/clamps to attach cable housing to the structure after installation and adjustment • Do not compress cable housing •Recheck to ensure cables move freelyRefer to T able 1 and Figure 11 for installation details.T able 1.

Each breaker needs two long rods and two short rods attached. The short (drive) rods will be attached first. 1. Slide the rubber boot toward the tip of the rod.2. Unthread the outer bulkhead nut and slide the nut and lock washer upwards.5Instructional Leaflet IL2C12863H08Effective March 2012Three-way cable interlock kit for Magnum drawout circuit breakers (Type 32 interlock)EATON CORPORATION 3. Slide the smaller diameter portion of bulkhead fitting in to the slot on the cable bracket (see Figure 12).4. Raise cable assembly until threads of the bulkhead fitting show above the slotted hole in the bracket (See Figure 12).5. Insert threaded end of rod into its swivel fitting.6. Bring the bulkhead washer and nut down to the threads and hand-tighten.7. Adjust the two bulkhead nuts to approximately center the fitting on the slot and hand-tighten.8. Replace the rubber boot over end of fitting.9. If short rod is in Position A (see Figure 11):a. Lower threaded rod tip back through swivel.b. Replace spacer tube and compression spring on rod end before sliding the rod tip through the swivel fitting of the lower lever. To aid in sliding the rod tip, grip the nuts that were tightened in Step 8.10. If short rod is in Position C (see Figure 11):a. Replace spacer tube on rod end.b. Replace compression spring on rod end.c. Manually compress the compression spring to replacethe lock nut.11. Replace the lock nut on the rod end.12. Hold the nuts that were tightened in Step 8 and use a 3/8-inch socket or a 3/8-inch open-ended wrench to tighten the lock nut until it touches the spacer tube. Torque to 30-40 in-lbs (3,3-4,5 Nm).Next, the long (driven) rods will be attached. The long rods areattached in the same way as the short rods except they do not use compression springs.Repeat the above processes for all cable ends. At the end of cable installation, the breakers should still be in the OPEN position.Figure 12. Step 10Figure 13. Step 10 - Short Rod Assembly (Position C)Figure 14. Step 10 - Long Rod Assembly (Position B)Step 11: This step describes how to adjust the cables. The initial adjustments are made with all breakers OPEN. The bulkhead nuts for each cable should be set so that the threaded bulkhead fitting is approximately centered on the cable bracket slot. Initial adjustments will be performed on the driven (long) rods.• Check the upper lever on each interlock assembly. There should be about a 1 mm gap between the top of the center slot in the lever and the top of the upper roller.6Instructional Leaflet IL2C12863H08Effective March 2012Three-way cable interlock kit for Magnum drawout circuit breakers(Type 32 interlock)EATON CORPORATION Figure 16. Step 11•If adjustment is needed, use the bulkhead nuts to appropriately adjust the cable housing. •T oo much clearance : adjust both bulkhead nuts to retract cable housing•No clearance : advance cable housing in a similar manner•For additional adjustment length : use bulkhead nuts on other end of cableAt the end of adjustment, adjust the rods using the upper cable nuts (tightened in Step 8) so that all upper levers are in the position demonstrated in Figure 16. Check the function of the mechanical interlock assembly according to the functional tests in the Step 12. Review Steps 3 – 12 and keep adjusting the interlock assembly until it functions correctly.Note: If experiencing difficulty or operating in a confined space, consider using an 11/16-inch flare nut crowfoot wrench drive to perform adjustments.Step 12: Perform the following functional tests and verify that the assembly conforms to all states in T able 2: 1.

RCDAT-8000-30Programmable AttenuatorUSB / Ethernet50Ω 0 – 30 dB, 0.25 dB step 1 to 8000 MHzProduct OverviewMini-Circuits’ RCDAT-8000-30 is a general purpose, single channel programmable attenuator suitable for a wide range of signal level control applications from 1 MHz to 8 GHz. The Attenuator provides 0 to 30 dB attenuation in 0.25 dB steps. Its unique design maintains linear attenuation change per dB, even at the highest attenuation settings.The attenuator is housed in a compact and rugged package with SMA female connectors on the bi-directional input and output RF ports, a standard Ethernet port (RJ45) and a USB type Mini-B power and control port.The attenuator can be controlled via USB or Ethernet (supporting both HTTP and Telnet network protocols). Full software support is provided and can be downloaded from our website any time at /softwaredownload/patt.html . The package includes our user-friendly GUI application for Windows ® and a full API with programming instructions for Windows ® and Linux ® environments (both 32-bit and 64-bit systems).Trademarks: Windows is a registered trademark of Microsoft Corporation in the United States and other countries.

There may be minor changes in performance when injecting signals to the RF Out port.2 Max accuracy defined as ±[absolute error+% of attenuation setting] for example when setting the attenuator to 26 dB attenuation the maximum error at 7500 MHz will be:±(1.45+0.035x26)= ±(1.45+91)= ± 2.35 dB3 Isolation is defined as max attenuation plus insertion loss; this is the path loss through the attenuator when initially powered up. After a brief delay (~0.5 sec typically) the attenuator will revert to a user defined “power-up” state (either max attenuation or a pre-set value).4 Total operating input power from both RF In and RF Out out ports. Compression level not noted as it exceeds max safe operating power level.5 Derate linearly from +28 dBm at 50 MHz to +17 dBm at 1MHz6 Tested with 1 MHz span between signals.7 Minimum Dwell Time is the time the RCDAT will take to respond to a command to change attenuation states without communication delays. In PC control add communication delays (on the order of msec for USB) to get actual response time.8Attenuation Transition Time is specified as the time between starting to change the attenuation state and settling on the requested attenuation state.Absolute Maximum RatingsOperating Temperature0°C to 50°CStorage Temperature-20°C to 85°CV USB Max.6VDC voltage at RF port16VTotal RF power for RF In & RF Out @1 - 50 MHzDerates linearly from+33 @ 50 MHz to+20 @ 1 MHz@ 50 - 8000 MHz+33 dBmPermanent damage may occur if any of these limits are exceeded.

GST-8320A终端器安装使用说明书
GST-LD-8320A终端器安装使用说明书(Ver.1.01,2008.06)一、概述在非编码火灾自动报警系统中,传统方式都是通过在回路终端连接一只电阻来维持系统的正常工作,一旦匹配不当将使整个报警系统工作不正常,甚至会产生误报警等问题。
GST-LD-8320A终端器(简称为终端器)与多线制火灾报警控制器或编址接口模块配套使用,取代了终端电阻,并有效地解决了上述一系列问题,大大提高了非编码报警系统的可靠性。
二、特点1.区域二总线,安装布线简单方便;2.可实现探测器被摘下报故障的功能;3.可作为底座使用,节省空间;4.工作稳定,性能可靠;5.抗干扰能力强。
三、技术特性1.工作电压:电源总线电压:DC24V 允许范围:DC15V~DC28V2.工作电流≤5mA3.等效电阻:4.7kΩ4.线制:区域二总线,有极性5.使用环境:温度:-10℃~+50℃相对湿度≤95%,不凝露6.外形尺寸:φ100mm×39mm7.外壳防护等级:IP328.壳体材料和颜色:ABS,象牙白9.重量:105g10.执行标准:GB 4717-2005四、结构特征与工作原理1.终端器结构特征如图1所示。
图1结构示意图2.工作原理终端器安装在多线制火灾报警控制器或编址接口模块构成的区域总线的最末端,当多线制火灾报警控制器或编址接口模块上电正常工作时,终端器作为负载,可以在电源电压上产生正负交替的、周期性的微分脉冲信号,由于编址接口模块中限流电阻的分压作用,使经过滤波后的电源电压降低,此时系统处于正常工作状态;当探测器被取下后,回路内引入了二极管,致使终端器产生的正负交替脉冲变成了单向脉冲,减小了终端器的负载能力,其结果使经过分压、滤波后的电源电压升高,多线制火灾报警控制器或编址接口模块可据此判断故障信号;区域总线短路、断路的判断方法与上述判断方法类似,不再重复。
终端器与多线制火灾报警控制器或编址接口模块配套使用不仅可以维持非编码报警系统的正常工作,还可以实现摘掉探测器报故障(不影响其它现场设备报火警),开路报故障、短路报火警等功能。
无人机远程喊话系统的设计与应用
无人机远程喊话系统的设计与应用摘要:精灵4作为微型无人机因其体积小、重量轻、携带方便在输电线路上应用十分广泛,特别是在精细化巡视和线路通道拍摄方面有着很好的实用性。
为拓展无人机在输电线路上的深度应用,将精灵4搭载喊话器作为一个新的应用方向进行研究。
为此,本文分析了无人机远程调谐系统的设计与应用。
关键词:无人机;远程喊话;设计应用引言研发适用于精灵4系列的轻小型智能喊话器,通过地面对讲系统实现无人机扩音器信号的同步传输,研究喊话器搭载于精灵4飞机的特殊结构及扩音技术,实现小型的远程、高效、便携的扩音系统。
1概念超高压输电公司管辖的是西电东送主网架超高压输电线路,线路电压等级为500kV及以上,线路杆塔高度从30米到100多米不等,尤其是新线路普遍杆塔高度70多米,对大跨越地区的杆塔甚至高达150多米。
在如此高的杆塔上作业,如果监护人员在地面监护塔上作业人员根本无法监护到位,即使有危险动作也没能够进行提醒或在开展检修作业过程中有什么难题需要提醒的根本无法跟塔上人员进行有效指导。
为了提高监护质量及指导塔上作业技术难点的工作,提出了利用无人机作辅助器高空喊话,采用无人机相机对高空作业人员作业流程进行实时监控,可填补这个安全漏洞,从而提高监护质量与安全。
2扩音喊话的功能优化目前,使用扩音器大部分停留在地面波声的阶段。
但是在高层建筑物轻生现场和向导人员疏散等救援现场,地面波拥挤,声音嘈杂,扩音器效果大大下降。
因此,使用无人机可以实现消防救援现场的高空呐喊,并在救援者等待救援的同时增强自信心。
除了消防救援实际情况外,无人机还安装了无线接收设备,地面救援人员到达现场后立即使用听筒喊,通过无线传输到无人机的接收设备,然后通过扩音器发出声音。
3远程控制系统在多机协作中,甚至在群集操作中,每个无人机的机载航空电子系统都可以具有特定的智能水平,但可以自己处理独特的相关任务,但仍然是有限度的。
单个无人机机载系统通常不能及时了解整个群集的整体工作环境状况。
CB-832 电路断路器和过载继电器测试装置 使用说明书
CB-832Circuit Breaker and Overload Relay Test SetI Digital memory ammeter I Digital, multirange timer I High-current outputISolid-state output initiate circuitDESCRIPTIONThe CB-832 test se is a high-current circuit breaker and overload relay test set. Model CB-832 is designed to test the circuit breaker and overload relays by means of primary current injection.The CB-832 is a self-contained test set that incorporates a variable high-current output and appropriate controlcircuitry and instrumentation for testing thermal, magnetic or solid-state motor overload relays; molded-case circuit breakers; and ground-fault trip devices.APPLICATIONSOne of the most common applications of the CB-832 is the calibration of magnetic overload relays, such as those used for protecting air conditioning systems. By providing up to 1000 amperes to simulate overload conditions, it also is capable of testing the time-delay characteristic of magnetic overload relays rated up to 500 amperes.In addition, the CB-832 can test the time-delaycharacteristics of thermal motor overload relays and molded-case circuit breakers rated up to 225 amperes,when following the recommended test procedure of testing the time delay of thermal devices at three times their rating.Higher currents are available for the short durations required to test an instantaneous trip element. Forexample, the test set will provide a short-duration output of 1800 amperes through a typical 225 ampere, molded-case circuit breaker. Additional applications include verifying the ratio of current transformers and testing panelboard ammeters and voltmeters.FEATURES AND BENEFITSI Digital memory ammeter:High-accuracy, direct-reading instrumenthas read-and-hold memory for measurement of short-duration currents.IDigital multirange timer:Crystal-controlled, high-accuracy instrument measures operating time to 1 millisecond.IHigh output current:Provides instantaneous currents up to 1800 amperes through a 225-ampere breaker.ISolid-state output initiate circuit:Solid-state circuit eliminates the need for contact maintenance.IProtection:Overload and short-circuit protection is incorporated.IEnclosure:Heavy-duty Formica enclosure is equipped with carrying handles and removable hinged cover that protects instruments and controls during transportation and storage. Space is provided for test lead storage.SPECIFICATIONSInput (specify one)120 V OR 240 V, 50/60 Hz, 1φ, 20ΑOutputOutput Ranges:Continuously adjustable in three ranges to meet a variety of test circuit impedances:0to 500 A at 3.5 V max.0to 125 A at 14 V max.0to 25 A at 70 V max.Output Capacity:The output circuit is designed to provide short-duration overloads.The output ranges will provide several times their current rating,provided the output voltage is sufficient to push the desired current through the impedance of the test circuit.The test set is capable of testing the time-delay characteristics of magnetic overload relays rated to 500 A using a test current of two times their rating (1000 A).avoid damage or overheating of the device under test while setting the test current.In the maintained mode, the output remains energized until manually turned off or, when performing timing tests, until the device under test operates—this both stops the timer and de-energizes the output.INSTRUMENTATIONAmmeterTo measure the output current, the test set incorporates a solid-state digital instrument with multiple ranges and a read-and-hold memory to measure short-duration currents.Operating Modes (switch-selected)Memory NormalDigital Display31/2digit, extra-bright LED display with 0.3-in.

The timer stops when the output current is interrupted.Normally Closed: Used to test a device with normally closedcontacts. The timer stops and the output is de-energized when the contacts open.Normally Open:Used to test a device with normally opencontacts. The timer stops and the output is de-energized when the contacts close.Dimensions14 H x 14.5 W x 13.4 D in.(356 H x 368 W x 343 D mm)Weight75 lb (34.1 kg)Overload Capability Percent Maximum Maximum Rated Time Time Current On Off 100 (1x)30 min 30 min 200 (2x) 3 min 8 min 300 (3x)30 s 4 min 400 (4x)7 s 2 minIt will test the time-delay characteristic of thermal devices rated upto 225 A using the recommended test current of three times their rating (675 A).Also, to perform an instantaneous trip test, it will provide 1800 A through a typical 225-ampere, molded-case circuit breaker.Overload Capability:To increase use of the test set, it isdesigned so that the current ratings may be exceeded for short durations.Because the magnitude of the output current is determined by the impedance of the load circuit, the voltage rating must be sufficient to push the desired current through the device under test and the connecting test leads.Output Initiate Circuit: The test set uses a solid-state output initiating circuit. To increase reliability and eliminate contact maintenance, this circuit uses a triac instead of a contactor to initiate the output.Output Initiate Control Circuit: The initiating control circuit provides momentary and maintained modes to control output duration.The momentary mode is used whenever the output is to be for a short duration.
