带负荷开断装置跌落式熔断器增加弹性辅助触头及灭弧室罩，用以分、合负载电流。
跌落式熔断器在正常运行时，熔丝管借助熔丝张紧，形成闭合位置。
当系统发生故障时，故障电流使熔丝迅速熔断，并形成电弧，消弧管受电弧灼热，分解出大量的气体，在管内形成很高压力，并沿管道形成纵吹，电弧被迅速拉长而熄灭，熔丝熔断后，下部动触头失去张力而下翻，锁紧机构释放熔丝管，熔丝管跌落，形成明显的开断位置。
带复合开端装置跌落式熔断器需要开断负荷时，绝缘杆拉开动触头，此时辅助触头仍然接触，继续用绝缘杆拉动触头，辅助触头也分离，在辅助触头之间产生电弧，电弧在灭弧罩中消逝能量，同时灭护罩产生气体，在电流过零时，将电弧熄灭。

This range ofcharacteristics is offeredin part by the production ofboth expulsion and current-limiting power fuses.Expulsion and current-limitingfuses provide such diversecharacteristics by employingdifferent areas of fusetechnology. These differencesin technology, along with thediverse characteristics, requirethat different questions beanswered when applyingexpulsion and current-limiting fuses.Product HistoryThe Eaton power fuse productline was introduced in the1930s by WestinghouseElectric Corporation. As powersystems grew in size, the needto sectionalize utility feedersand to protect equipmentbecame apparent. The initialfuse development effortsresulted in the creation ofnon-current-limiting, expulsiontype fuses. As the availablefault currents grew, the needfor a current-limiting fuse wasapparent and this resulted innew interruption techniques.While basic fuse technologyhas not changed greatlyover the years, gradualimprovements have beenmade to make the fusesmore current-limiting andeasier to manufacture andinstall. Because standardsfor fuses (ANSI C37) detailonly test methods and basicperformance requirements,many different varieties offuses (length, diameter, short-circuit interruption curves)have been introduced overthe years.Eaton presently manufacturesmedium voltage fuses inHaina, DR.Product History Time LineFuses in PerspectiveAdvantagesMedium Voltage Fuse ComparisonNotes1BAL superseded by CLE.2BAL-R superseded by CLS.3BA—Refills and holders only, new installations use RBA.4DBA—Refills only.5DBS—Superseded by DBU.VoltageTypeClassApplicationAmp RatingExpulsion Current-LimitingVented SealedElectromechanical StaticExpels gases/noise No gases/noiseInterrupts at natural current zero Limits fault currentGenerally higher voltage/current applications Generally higher interrupting ratingsDifferences in time/current characteristics Differences in time/current characteristics1818Medium Voltage FusesCurrent-Limiting and Expulsion FusesApplication GuideGuide to NamesBCLS—Bolt-in version of CLS fuse .BHLE—Bolt-in version of HLE fuse.CLE —Current-limiting E-rated.HLE/HCL —Current-limiting E-rated, interchangeable with General Electric and Gould Shawmut.CX/CXN —Current-limiting interchangeable with McGraw-Edison’s NX brand fuses, C-rated.CLT —Current-limiting transformer fuse.CLPT —Current-limiting E-rated for potential transformers.CLS —Current-limiting for motor starters, R-rated.RBA —Refillable boric acid expulsion fuse (indoor use).RDB —Refillable dropout boric acid expulsion fuse (outdoor use).DBU —Dropout boric acid fuse interchangeable with S&C’s SMU-20 refill.Guide to Ampere Ratings“E” DesignationFuse rated 100E or below will melt in 300 seconds at a current value between 2.0 and 2.4 times the E number.Fuse rated above 100E will melt in 600 seconds at a current value between 2.2 and 2.64 times the E number.If the current is higher than 2.4 or 2.64 times the E number, the user must consult the time-currentcurves for that particular fuse.“R” DesignationThe fuse will melt in 15 to 35 seconds when the current equals 100 times the R number.If the current is higher than 100 times the R number, the user must consult the time-current curves for that fuse.“C” DesignationThe fuse will melt in1000 seconds at a current value, between 1.7 and 2.4 times the C number.If the current is higher than 2.4 times the C number, the user must consult the time-current curves for that particular fuse.“A” DesignationFuses that do not comply with “E,” “R” or “C” designations.Expulsion fuses can also be E-rated, K-rated and T-rated, and are also covered in the ANSI standards. The K and T ratings refer, respectively, to relatively “fast” and “slow” melting expulsion fuses. Detailed time-current tables adequately define these ratings.Selection GuideRatingsFeeder Circuit Section-alizing Fused Switches Power Trans-formersSubstationService Trans-formers DIP Pole Underground DistributionTransformersPole-MountedTrans-formers Pad-Mounted Distribution Transformers Motor Starters Potential Trans-formers Sub-stationCapacitorBanksType Class UseBrand kV,Ampere,kACurrent limitingGeneral purposePower BHLE/CLE/HLE/HCL 2.4–15.5 kV 10E–1350A to 85 kA ■■■■■Dist.CX/CXN 4.3–15.5 kV 3.5C–300C 50 kA ■■CLT2.4–15.5 kV 4A–150A 25 kA ■Backup Power CLPT2.4–38 kV 0.25E–10E to 80 kA ■Power BCLS/CLS2.4–8.3 kV 2R–36R 50 kA ■ExpulsionBoric acidPower RBA4.8–34.5 kV 0.5E–720E ■■■■RDB 4.8–34.5 kV 0.5E–720E ■■■■■■DBU14.4–38 kV 5E–200E 15SE–200SE 3K–200K■■■■■■1818Medium Voltage FusesCurrent-Limiting FusesCurrent-Limiting FusesCLE and HLE Current-Limiting—E-RatedCLPT Current-Limiting E-Rated forPotential Transformer ProtectionCLS Current-Limiting for Motor StarterCX Current-Limiting—Interchangeablewith McGraw Edison’s NX TypeCLT Current-Limitingfor Transformer ProtectionProduct DescriptionCurrent-limiting fuses areconstructed with pure silverfuse elements, a high-puritysilica sand filler, a speciallydesigned core and a glassresin outer casing.A high fault current melts thesilver element almost instantlyand loses energy to thesurrounding sand. The sandmelts and forms fulgurite,a glass-like substance.The arc voltage rapidlyincreases to nearly threetimes the fuse voltage ratingand forces the current tozero. Low fault current meltsa solder drop on the silverfuse element that, in turn,melts the silver.The element burns back untilthere is a sufficient internalgap to interrupt the current.This is known as the M-effect.Eaton current-limiting fusesare offered in two basictypes: backup and generalpurpose. Backup fuseshave a published minimuminterrupting current andrequire a series device forbreaking the circuit forcurrents below this minimumlevel. General purpose fuseshave improved low currentinterruption capability and aredesigned to interrupt low faultcurrents that cause the fuse tomelt in one hour or less.General InformationApplicationsCurrent-limiting technologiescan be used to meet almostevery fuse application. Typicalapplications for utility,industrial, construction andOEM customers include:●Feeder circuitsectionalizing●Power transformers●Substation servicetransformers●Underground distributiontransformers●Pole-mountedtransformers●Pad-mounted distributiontransformers●Fused switches●DIP poles●Motor starters●Potential transformers●Substation capacitor banksAccessoriesA wide assortment ofmountings, live parts andend fittings are availableto facilitate power fuseinstallation.Mountings include a base,porcelain or glass polyesterinsulators and live parts. Theyhelp enable the fuse to besafely attached to the gear.Mountings can be eitherdisconnect or nondisconnect.Live Parts attach the fuseto the mountings and areconsidered part of themounting. All parts abovethe insulators are live parts.Live PartsEnd Fittings are metal partsthat attach to each end ofthe fuse at the ferrules.They are used only ondisconnect fuses or whenconverting a nondisconnectto a disconnect fuse.1818Medium Voltage FusesExpulsion FusesExpulsion FusesRBA—Refillable Boric AcidRDB—Refillable Dropout Boric AcidDBU—Dropout Boric Acid—Interchangeable with S&C’s SMU-20Product DescriptionEaton expulsion fuses use boric acid as theinterrupting medium. Under a fault condition, arc heat decomposes the boric acid, which produces gases and boric anhydride. The water vapor blast extinguishes the arc in a deionizing action and exits from the bottom of the fuse.Type RBA indoor expulsion fuses are fitted with a filter or condenser that moderates the discharge exhaust. The discharge filter limits the exhaust to a small and relatively inert amount of gas and lowers the noise level without affecting the fuse interrupting rating. Steam discharge, that can affect the interrupting, is fully restricted by the condenser.Each type RDB outdoor dropout fuse includes an ejector pin that is forced through the top of the fuse. The ejector pin releases a latch on the mounting and the fuseholder is kicked outward and swings into the dropout position, through 180° with a vertical mounting, or 90° with an underslug mounting.Refill units can be fieldinstalled into RBA and RDB expulsion fuses. Once the old unit has been removed, the separately purchased unit can be easily installed into the fuse holder.General InformationApplicationsExpulsion technologies can be used to meet a number of fuse applications. Typical applications for utility, industrial construction and OEM customers include:●Feeder circuit sectionalizing ●Fused switches ●Power transformers ●Substation service transformers ●DIP poles●Potential transformers●Substation capacitor banksAccessoriesThe following accessories are available for expulsion fuses:Mountings include a base, porcelain or glass polyester insulators and live parts. They help enable the fuse to be safely attached to the gear. Mountings can be either disconnect, nondisconnect or dropout. Fuses may be vertical or underhung.Live Parts attach the fuse to the mountings and are considered part of the mounting. All parts above the insulators are live parts.End Fittings must bemounted on DBU fuse units to enable them to be fitted into the mounting.Filters and Condensers are for indoor applications of RBA expulsion fuses. They confine the arc within the fuse and substantially reduce the noise and exhaust when the fuse interrupts.Mufflers are used with DBU fuses in indoor applications to virtually eliminate offensive noise and exhaust gases when the fuse interrupts.18Medium Voltage FusesCurrent-Limiting and Expulsion FusesProduct SelectionEasy to Use, Easy to Order!

RW4型、RW10型户外高压跌开式熔断器
RW4型、RW10型户外高压跌开式熔断器跌开式熔断器又称跌路式熔断器，广泛用于环境正常的宰外场所，它既可作6—10Lv线路和设备的短路保护，又可在一定条件下，直接用高压绝缘钓棒来操作熔管的分合，起高压隔离开关的作用。
—般的跌开式熔断器只能无负荷操作，或通断小容量的空载变乐器和空载线路等。
图4—2是RW4—l0(G)型跌好式熔断器的基本结构。
正常运行时，其熔管上端的动触头借熔姓张力拉紧厉，利用绝缘钩棒将此动触头报人卜静触头内锁紧，向时F动触头与厂静触头也相互压紧，从而使电路接通。
当线路上发生短路时，短路电流使熔丝熔断，形成电弧。
熔管(消弧管)内壁出于电弧烧灼而分解出大量气体，使管内压力剧增，并沿管道形成强烈的气流纵向吹弧，TI代理商使屯弧迅速熄灭。
熔管的F动触头阑熔丝熔断后火去张力航下翻，使锁紧机构释放熔管，在触头弹力及熔管自至的作用下．回转跌开，造成明显可见的断开间隙。
RW10—10(F)型跌开式熔断器是在一般跌开式熔断器的上静触头上面加装一个简单的灭弧室，因而能够带负荷操作o这种负荷型跌开式熔断器既能实现短路保护，又能锵负荷操作。
跌开式熔断器依靠电弧燃烧使产气消弧管分解产生的气体来熄灭电弧，即使是负荷型跌开式熔断器加装有简单的灭弧室，其灭弧能力都不强，灭弧速度不快，不能在短路电流达到冲击位之前熄灭电弧，因此，它届“非限流式“熔断器。
高压隔离开关高压隔离开关的功能主要是隔离高压电源，以保证其他设备和线路的安全检修。
因此，其断升后有明显可见的断开间隙，而且断开间隙的绝缘及相间绝缘都是足够可靠的，能充分保障人身和设备的安全。
但是隔离开义没有专门的灭弧装置，因此，它不允许带负荷操作。
然而可用来通断一定的小电流，如励磁电流(空载电流)不超过2A的空载变压器，电容电流不超过5A的空载线路以及电压互感器和避雷器电路等。
高乐隔离开关按安装地点分户内式和户外式两大类。
图4—3是GN8—10／600型户内高压隔离开关的外形结构图。
