The ABB OVR recloser isable to meet present recloser demands, plus offer advanced capabilities suchas fault location, adaptive protection, control monitoring, power quality,communications, single phase tripping and loop control for tomorrow’sneeds.2Improved Distribution System Reliability Conventional methods for improving system reliability include tree trimming, animal guards,lightening protection, and maintaining problem circuits. However, many of today’s utilities aremoving toward specialized system configurations, such as midpoint reclosers, tie reclosers, loop configurations, and single phase reclosing to improve reliability. These configurations,combined with remote communication, can substantially improve reliability indices,subsequently enhancing customer service and maximizing shareholder value.Utilities are receiving pressure to improvereliability from three stakeholders:•customers•industry regulators•company ownersCustomersCustomers expect a level of reliability equal to, orbetter than, the reliability they have had.Furthermore, an increasing number of customersare operating businesses, which are sensitive toreliability and service quality.Industry RegulatorsIndustry regulators, or Public Utility Commissions, are increasinglyconsidering performance-based regulation mechanisms, whichexplicitly state reliability penalty targets. These regulatorycommissions are monitoring several indices such as:•System Average Interruption Frequency (SAIFI)•System Average Interruption Duration (SAIDI)•Momentary Average Interruption Frequency (MAIFI).These indices are accompanied by financial bonuses or penaltiesthat directly impact the utility's bottom line.Company OwnersShareholders or company owners expectsuitable rates of return. All capital, operationaland maintenance expenditures are selected tomaximize results.34Benefits of High Voltage Unit•Compact, lightweight design for easy installation•Superior life - rated for 10,000 operations•Environmentally friendly - no oil or gas•HCEP encapsulating material reduces weathering erosionand outdoor aging, improving life expectancy•Vacuum interruption for maximum reliability andminimum maintenance•Magnetic actuation with fewer moving parts andless maintenance•Stainless steel enclosure to prevent corrosion in harshenvironmentsReliability by Design15 kV27 kV38 kVReliability by DesignBenefits of Control Unit•Simple, menu-driven programming for easy use•Hot line tagging feature on faceplate for simpleand safe operation•Easy access front RS-232 port•Button on front panel (Counters) for easy access tooperational data•Over 50 protection curves and 3 user programmablecurves for superior coordination•Single phase tripping option reduces outages•Optional loop control module for fast restoration of distribution systems•Fault location reduces outage time••and interruptions•in harsh environments•to save installation time and money•input (85 - 265 VAC/DC)6Pole assembly–Resistant to vandalization–Maintenance free: tested to 10,000 mechanical operationswithout degradation–Few moving parts–High creepage pole design–Easy to replace individual poles–Superior HCEP encapsulating material for outdoorapplicationsInsulating material–Advanced epoxy (HCEP) encapsulating material–Light weight for easy handling–Increased weather durability and improved aging–Improved performance in heavily polluted areasVacuum interrupters–Maximum reliability–Design ensures superior contact wear and long life–Superior life: 10,000 load operations–Minimal maintenance–Environmentally friendlyIntegrated sensors–Provides required signals for current protection, meteringand data gathering–Sized for superior response up to the full-rated faultcurrent–Reliable and accurate data for waveform analysis–One sensor per phaseMechanical trip–Pulling yellow handle down will mechanically open allthree poles of the OVR unit–Lockout function is conveniently performed using theavailable hot-line tagging switch on the OVR control unit–Optional close block feature for manual tripReliability by Design7Position switch–One per pole–Determines pole open or closed positions–Allows independent pole operation–Provides positive pole position feedback to the OVRcontrol unit–Double break, galvanically separate contacts–Self-cleaning contact points by wiping action–Gold contacts for low currents and voltages at low contacttransfer–Transparent green housing allows the contact positionand internal mechanism to be easily viewedMagnetic actuators–Increased reliability - rated to 10,000 operations–Simple design –Bi-stable - no power required to hold contacts open orclosed–Few moving parts mean low maintenance and highreliability–Three individual actuators eliminate complicated linkagesOutdoor cabinet–304 stainless steel enclosure prevents corrosion–Eliminates environmental and maintenance concernsof oil or gas–Option for up to six voltage inputs into the highvoltage cabinet eliminates the need to run cables to thelow voltage cabinet–Shunt resistors allow for disconnecting control cablewithout open circuiting current sensorsOpen/Close indicators (on bottom)–Individual phase position indicators–Highly visible from the ground–Large and easy to viewReliability by Design8Reliability by Design3D Modeling: Advanced Design TechnologyAdvances in simulation software allow for the virtual design and testing of poles and actuators prior to any actual manufacturing and testing. This gives ABB the ability to use 3D electrostatic modeling on the poles to design improvements, minimize partialdischarge and construct dielectrically robust poles. This design process minimizes therisk of field failures over the life of the product.ABB Vacuum Interruption:Improved InterrupterABB has been developing and manufacturingvacuum interrupters since the early 1980's.Worldwide, more than one million ABB vacuuminterrupters are in service. ABB's vacuuminterrupter facility uses the latest technologies inhigh quality mass production to produce the nextgeneration of vacuum interrupter. This newgeneration vacuum interrupter is robust foruniversal application.Vacuum interrupters are compact, maintenance-free,with a long service life, and excellent environmentalcompatibility. Vacuum technology fits very well withthe recloser requirements since it can easily handlefrequent operations. Additionally, vacuuminterrupters do not need any extra time to recover,so even the first reclosing operation (after 100-300msec) is not a problem.9HCEP: Cutting Edge Insulating MaterialThe OVR insulating material is Hydrophobic Cycloaliphatic Epoxy(HCEP). HCEP is the next generation of Cycloaliphatic Epoxy(CEP).Hydrophobicity means resistance to water. It is advantageous foroutdoor applications because it prevents water from developingcompletely wetted, resistive conductive surfaces. Leakage currents aretherefore reduced, which helps to reduce the flashover risk. The resultis enhanced reliability. Furthermore, less discharge activity means lessattack and therefore less surface erosion, improving insulators’ lifeexpectancy.Reliability by Design+ = positiveo = neutralAdvantages of HCEP over CEP-Improved performance in heavily polluted areas-Improved weatherability and outdoor aging-Increased life expectancy-Enhanced reliabilityWhy do we need Hydrophobicity?-Improved water beading and runoff-Lower leakage currents-Less discharge activity-Lower flash-over probability-Less erosion-Better reliability-Improved life expectancy10Local human-machine interface–Enlarged LCD (1” x 5”) with large characters (two lines of 20 characters)–Simple menu-driven programming using large six-button keypad–Backlit display indicates metering values, fault information and location–Temperature compensatedIndicator lights–Continual self-checking with status indication–Pickup and lockout indicationFront panel pushbuttons–Remote or local selection between three setting groups: Primary, Alternate 1 (Alt 1) and Alternate 2 (Alt 2)–Front panel button to set Alt 1 settings–Ground blocked, remote blocked, and reclose blocked pushbuttons–Sensitive Earth Fault (SEF) is optional, recommended for ungrounded or Delta CT applications –PROG 1 battery test feature preprogrammed–User programmable LEDs for alarms, additional targets, etc.–Counters button for easy access to number of operations and overcurrent trip information Hot line tagging feature–On faceplate for simpler and safer operation–Can be mapped for multiple applicationsFront mounted RS-232 port–Independent from rear mounted RS-232 port–Easy download and upload of data on-site using WinPCDSeparate open and close pushbuttons–Separate indicator light for easier viewing–ANSI or IEC coloring for individual practices123456Reliability by DesignPCD Control UnitReliability by Design2134651112Control cabinet–304 stainless steel cabinet, NEMA 3R with drip shield –Battery provides full operational capability for 48+ hours –Ample space for mounting communications equipment –Three-point latching with padlockable handle –Vented designGFI–Ground fault receptacle provides AC power for a laptopCommunication & I/O ports–Isolated RS-232 and RS-485 ports–ST fiber optic ports for interference-free communication;

There are several indices developed for reliability of service that utilities account for and track. These indices include System Average Interruption Frequency Index (SAIDI), System Average Interruption Duration (SAIDI), andMomentary Average Interruption Frequency Index (MAIFI). Currently, most utilities are measured by the Public Utilities Commission to assure they meet a minimum requirement with respect to these indices. Thesemeasurements are being utilized to assess penalty/performance-based rates at the utilities, making it is necessary to achieve higher reliability. Below are some examples of how current technology can improve reliability and reduce system outages.SubstationSubstation10 Miles 1,800 Customers5 Miles5 MilesRecloserRecloserRecloserSingle Phase TrippingThe OVR recloser is the first of its kind in the industry. It includes fast acting, maintenance free, independent-pole, magnetic actuation instead of a ganged-pole mechanism. The single phase tripping option is flexible bydesign in order to meet virtually all current and future customer needs. The three global modes available are:1.Three phase tripping2.Single phase tripping OPUP (only picked up phases trip)3.Single phase tripping OOAP (one or all phases trip)Each step of the reclose cycle can be individually configured to single or three phase trip to lockout for each of the protective functions. Two common examples would be:1.The recloser is set to trip on single phase and lockout on all three phases if fault is permanent.2.The recloser is set up to both trip and lockout on single phase.˜˜15Case 3: Loop Configuration without Single Phase Tripping SAIDI: 2.1hrs/yr (36% reduction)SAIFI: 1.0int/cust/yr (37% reduction)MAIFI: 6.8mom/yr (22% reduction)Loop Configurationwith Single Phase Tripping SAIDI: 1.8hrs/yr (45% reduction)SAIFI:0.8int/cust/yr (50% reduction)MAIFI: 3.1mom/yr (64% reduction)Loop ControlABB's Loop Control Module (LCM) is completely compatible with the PCD. The LCM detects either normal voltage or loss of voltage, from one or two sources. It initiates preprogrammed logical steps to isolate the faulted section, depending upon the voltage configuration and feeder location.The LCM provides a loop control function to sectionalize or remove the faulted section from the distribution system. This control module provides sectionalizing control of either a recloser or a switch, and restores the distribution system by closing the tie-point recloser from another electrical source.The LCM allows individual reclosers to act as a sectionalizer, midpoint or tie, without physical con-nections to other reclosers, allowing it to be installed in existing feeder automation systems.Application SummaryThe OVR's feature sets are well-suited for these specialty applications. Through the use of single phase tripping and loop control schemes, utilities can reduce their yearly outage time up to 45%.SubstationSubstationBreakerBreakerN.C.RecloserN.C.RecloserN.O.Recloser5 Miles5 MilesExcellent Customer Support16OVRCustomer Support:•Free 24-7 technical supportline•Feeder Automation Userswebsite features:-News-Frequently Asked Questions-Discussion Board-Technical Information-Product Brochures-Software Downloads-Contact Information-Instruction Manuals-Programming Shortcuts-Drawings•Training-Multi-Track Factory Based Training•Lineman Track•Engineering Track-Multi-Track Field Based Training•Lineman Track•Engineering Track-Mobile Training Aids•Unique tool incorporates a complete recloser and PCD with the LCM and simulates loop schemes using four PCDs withLCMs to demonstrate the schemes.

ABB高压 GIS结构及二次回路分析摘要：本文先对ABB厂家的高压GIS设备的二次回路进行简单的介绍，后以500kV某站500kV GIS设备为例，重点分析其断路器机构二次回路的设计逻辑，并结合南方电网的相关反措，深入探讨其改进措施。
关键字：跳闸回路合闸回路防跳回路三相不一致回路南网反措1高压GIS机构二次回路1.1 断路器合闸回路以断路器A相合闸回路为例进行分析：图1.1 断路器A相分合闸回路机构中的合闸监视回路通常与操作箱中的TWJ继电器串联，监视合闸回路是否具备合闸条件，即判断合闸回路是否完好。
如图1.1所示，合闸监视回路串联了断路器常闭辅助接点，当刀闸处于分闸状态时，常闭点闭合，合闸回路完好；当刀闸处于合闸状态时，常闭点断开，合闸回路无法导通。
合闸回路满足合闸条件后，当断路器收到就地合闸指令时，合闸继电器K0E励磁，就地合闸回路中的K0E常开点闭合，合闸回路导通；当断路器遥控合闸时，转换把手打到远方位置，一旦收到合闸命令，合闸回路导通。
防跳回路提供防止开关跳跃的功能，是控制回路中必不可少的部分。
开关跳跃是指由于合闸回路的合闸接点粘连或未能及时返回等原因，导致合闸输出端一直带有电压，因此当开关因故障跳开后，又会因为合闸电压再次合上，造成断路器连续切合的现象，导致开关损坏甚至爆炸。
保护装置和机构内都有防跳回路。
常规的防跳回路接线如图1.2所示，由于机构防跳回路中串接了断路器的常开辅助接点，若两套防跳同时接入回路，当开关合闸后，开关常开辅助节点DL闭合，+KM—TWJ—R—DL常开点—K11—-KM之间构成一条寄生回路。
一旦两套防跳之间的参数配合不当，将导致防跳功能失效、跳位监视异常和合闸回路异常等现象。
因此新装置都已取消了保护防跳回路，只保留机构防跳功能。
图1.2 常规防跳回路接线图为了解决寄生回路的问题，ABB的断路器防跳回路先串接断路器的常闭辅助接点，再串接断路器的常开早合点和防跳继电器K201。
断路器按其使用范围分为高压断路器，和低压断路器，高低压界线划分比较模糊，一般将3kV以上的成为高压电器。
低压断路器又称自动开关，它是一种既有手动开关作用，又能自动进行失压、欠压、过载、和短路保护的电器。
它可用来分配电能，不频繁地启动异步电动机，对电源线路及电动机等实行保护，当它们发生严重的过载或者短路及欠压等故障时能自动切断电路，其功能相当于熔断器式开关与过欠热继电器等的组合。
而且在分断故障电流后一般不需要变更零部件，一获得了广泛的应用。
分类：按操作方式分有：电动操作、储能操作和手动操作。
按结构分有：万能式和塑壳式。
按使用类别分有：选择型和非选择型。
按灭弧介质分有：油浸式、真空式和空气式。
按动作速度分有：快速型和普通型。
按极数分有：单级、二级、三级和四级等。
按安装方式分有：插入式、固定式和抽屉式等。
高压断路器(或称高压开关)是变电所主要的电力控制设备,具有灭弧特性,当系统正常运行时,它能切断和接通线路及各种电气设备的空载和负载电流;当系统发生故障时,它和继电保护配合,能迅速切断故障电流,以防止扩大事故范围.因此,高压断路器工作的好坏,直接影响到电力系统的安全运行；高压断路器种类很多，按其灭弧的不同，可分为：油断路器（多油断路器、少油断路器）、六氟化硫断路器（SF6断路器）、真空断路器、压缩空气断路器等高压开关额定电压1kV及以上主要用于开断和关合导电回路的电器。
高压负荷开关高压负荷开关是一种功能介于高压断路器和高压隔离开关之间的电器，高压负荷开关常与高压熔断器串联配合使用；用于控制电力变压器。
高压负荷开关具有简单的灭弧装置，因为能通断一定的负荷电流和过负荷电流。
但是它不能断开短路电流，所以它一般与高压熔断器串联使用，借助熔断器来进行短路保护。
功能在规定的使用条件下，可以接通和断开一定容量的空载变压器（室内315KVA，室外500KVA）；可以接通和断开一定长度的空载架空线路（室内5KM，室外10KM）；可以接通和断开一定长度的空载电缆线路。
