自脱离三相组合式过电压保护装置说明书(SHK-BOD)

BOD(保的）R自脱离过电压保护装置产品型号：SHK-BOD由于过电压能量过大、超期服役、产品质量等原因造成过电压保护器和避雷器的氧化锌阀片烧毁，并导致相间短路的事故时有发生。

由于对截面选择、电缆长度、线间距离处理不当，全密封结构过电压保护器的引线电缆没能有效发挥安全脱离的作用。

大量的事故致使对过电压保护器和氧化锌避雷器失去信息，一些用户拆除现有安装使用的过电压保护器，少数用户拒绝在中压配网装设过电压保护器和氧化锌避雷器。

为解决三相组合式过电压保护器的安全自脱离问题，我公司利用自主知识产权的过电压保护器脱离技术，专门开发出BOD型自脱离过电压保护器，于2009年获得了国家发明专利（ZL 2009 1 0116080.6）和实用新型专利（ZL 2009 2 0142756.4）。

产品用途：●装设在进出线开关柜的线路侧，可有效限制电网的内部过电压和真空开关开断过程中发生在线路侧的操作过电压；●装设在电压互感器柜，可有效限制电网的内部过电压和真空开关开断过程中发生在电源侧的操作过电压。

产品功能：●能有效限制发生在相与地之间和相与相的大气过电压和电网的各类内部过电压。

●具有动作计数和脱离器状态监测功能。

●配置RS—485通讯接口，可通过网线与监控系统实现数据远传。

装置特点：●采用放电间隙与氧化锌阀片串联作为基本保护单元，巧妙地解决了用于中性点非有效接地系统的避雷器和过电压保护器普遍存在的限制过电压与自身安全的矛盾。

●串联间隙与氧化锌阀片在参数方面的巧妙配合，两者互为保护，无间隙、无续流，动作寿命至少可达10000次。

●采用四星型对称结构，相间保护特性与相对低保护特性相同，更有利于保护相间绝缘。

●采用阻性放电间隙，大大降低了冲击系数。

●当氧化锌氧化锌阀片崩溃后脱离器可在1～2ms之内可靠动作，可有效避免氧化锌阀片烧毁导致的相间短路事故。

三相组合式过电压保护器产品型号：SHK-TBP6～35kV中压系统，随着真空断路器的大量采用产生操作过电压更加频繁，线路电缆化使得弧光接地过电压明显提高。

中压电网普遍采用的交联电缆等固体绝缘设备，在操作过电压、弧光接地以及铁磁谐振过等电网内部电压长期持续的积累性破坏下，绝缘事故频繁发生。

除了对雷电过电压进行有效防护之外，对发生在相对地和相与相之间的各种内部过电压也必须采取有效地限制措施，以大幅度地延长固体绝缘设备的运行寿命。

为此有效的限制相间和相对地的各类过电压，我公司开发了SHK-TBP型三相组合式过电压保护器，曾于1993年获得国家专利（ZL93 2 03502.7），并于2009年再次获得实用新型专利（ZL 2009 2 0142758.3）产品用途：●装设在进出线开关柜的线路侧，可有效限制电网的内部过电压和真空开关开断过程中发生在线路侧的操作过电压；●装设在电压互感器柜，可有效限制电网的内部过电压和真空开关开断过程中发生在电源侧的操作过电压。

产品功能：●能有效限制大气过电压以及发生在相与地之间的各类过电压；●能有效限制发生在相与相之间的各类过电压；●可按用户要求配置动作计数功能。

●软连接的引线电缆可作为自动脱离器，防止阀片烧毁之后引起相间短路事故。

产品特点：●采用放电间隙与氧化锌阀片串联作为基本保护单元，巧妙地解决了用于中性点非有效接地系统的避雷器和过电压保护器普遍存在的限制过电压与自身安全的矛盾。

●串联间隙与氧化锌阀片在参数方面的巧妙配合，两者互为保护，无间隙、无续流，动作寿命至少可达10000次。

●采用四星型对称结构，相间保护特性与相对低保护特性相同，更有利于保护相间绝缘。

●采用特殊配方和特殊工艺烧制的“瓷环”作为放电间隙，冲击系数等于1，保护特性不受过电压频率和波形的影响，保护性能稳定。

●采用硅橡胶外套和外引高压电缆的全密封结构，保护性能不受外界环境条件的影响，可方便地直接安装在开关柜的手车底盘上或互感器室内。

过电压保护装置使用说明书过电压保护装置使用说明一、产品用途三相组合式过电压保护器主要用于发电、供电和用电企业的电力电网中。

用来保护变压器、开关、母线、电动机等电气设备，可限制大气过电压及各种开关引起的操作过电压，对相间和相对地的过电压均能起到可靠的限制作用。

二、结构/特点三相组合式过电压保护器的电气原理如图（1)所示，图中FR为氧化锌非线形电阻,CG为放电间隙，由于采用对称结构，其中任意三个可分别接入A、B、C三相,另一个接地线。

三相组合式过电压保护器具有下面的一些特点：1．用氧化锌非线性电阻和放电间隙的结构,使两者互为保护。

放电间隙使氧化锌电阻的荷电率为零,氧化锌电阻的非线性特性又使放电间隙动作后无续流，放电间隙不再承担灭弧任务,提高了产品的使用寿命。

2．采用四星形接法,对相间和相对地的过电压均能起到可靠的限制作用。

可将相间过电压大大降低，保护的可靠性大为提高。

3.在各种电压波形下放电值均相等,不受各种操作过电压波形的影响，过电压保护值准确,保护性能优良。

４.使用环境温度为-400C～＋600Ｃ,海拔高度小于2000m。

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.

完整的系统过电压保护解决方案！超宽脱离短路电流范围300A～100KABOD自动脱离式、大容量免维护三相组合式过电压保护装置说明书3～10KV系统BOD-I型：普通型BOD-II型：有通讯接口上海合凯电力保护设备有限公司产品简介上海合凯电力保护设备有限公司是凯立集团所属的制造三相组合式过电压保护器的专业子公司，本公司生产的TBP自上世纪90年代初期诞生以来，已为我国的电力事业作出了巨大贡献。

但是，由于认识和实验技术上的局限，早期TBP以及后来其它企业派生出的各种类型的三相组合式过电压保护器都没有成熟有效的故障退出手段，以至于，在系统谐振或者其他恶劣条件下，保护器本身发生崩溃，进而引发开关柜内相间短路，给用户造成生产和物质上的损失，有时还有较大的间接经济损失。

无论是用户还是保护器制造厂家都非常清楚的看到目前过电压保护方案存在的不足，但是苦于没有切实有效的解决办法，只能忍受现状。

凯立集团一直坚持研发为主的宗旨，不断的完善和充实实验设备，目前已具备我国最大的200KA 短路电流的实验条件，通过一年多的试制，终于完成了过电压保护器的脱离技术，并获得了实用新型专利。

目前由上海合凯电力保护设备有限公司生产的BOD，命名为：大容量、自脱式、免维护、三相过电压保护装置，添加了保护功能、运行检测功能、故障自动脱离功能，结束了早期单纯的三相组合式过电压保护器的不完善之处，可在内部发生击穿时，快速自动脱离系统，由于实现了自动脱离功能，因此，也免去了定期检测保护器的工作，同时整合了光电耦合技术，增加了脱离器状态检测、保护装置动作计数、网络通信接口等功能，真正实现了完整的过电压保护解决方案，并与现场自动化管理接轨。

完整的系统过电压保护解决方案1.传统的过电压保护解决方案●只针对过电压进行限制，没有自身故障退出功能；●当保护器本体故障时，一般会引发柜内相间短路，造成柜体爆炸。

过电压保护元件的性能总是要蜕变的：i.频繁的系统操作过电压会导致保护元件逐渐老化，最终被击穿；ii.系统谐振过电压会导致保护元件极速老化，或者直接击穿；iii.系统在快速（<1ms）切除短路故障时，回路电感（尤其是电源变压器）储存的能量会导致保护元件极速老化，或者直接击穿；iv.保护器若漏气或受潮，会导致保护元件性能快速蜕变，极易造成内部闪络或击穿。

阻容三相复合式过电压保护器使用说明书一型号说明二产品用途SYB-ZR三相复合式过电压保护器是针对现行各类过电压保护器保护弱点而设计的新一代保护装置，其将阻容吸收器和避雷器的功能有机地结合在一起。

主要用于吸收真空断路器、真空接触器在开断感性负载时产生的高频操作过电压，同时具有吸收大气过电压及其它形式的暂态冲击过电压的功能。

可广泛地用于真空断路器操作的电动机、电抗器、变压器等配电线路中。

三产品优点及特点：本产品内部为氧化锌阀片和电阻电容的有机结合，兼有传统氧化锌型保护器和阻容吸收器的优点，又从根本上克服了单纯氧化锌阀片型保护器和阻容吸收器各自不可避免的缺点。

性能优异，安全可靠。

A 本产品保护特性如下：(1) 当系统在正常运行中，保护器阻容回路中的电阻仅通过µA级电流，电容回路不接入系统，不会对系统提供附加接地电容电流，有利于整体电路设计以保证系统稳定工作，且减轻了高次谐波对电容的损伤。

（2）当系统出现幅值较小的过电压时，阻容吸收器工作，吸收高频过电压，对所保护的设备提供真正的弱绝缘保护。

（3）当系统过电压幅值较大（如：雷电过电压）时，避雷器回路工作，释放高幅值能量，将过电压幅值限制在一定范围内，以保护设备的绝缘不受损坏。

B 本产品与其它过电压保护产品对比其性能优点如下：(1) 具有阻容吸收器和金属氧化物避雷器（或过电压保护器）的双重功能。

（2）阻容回路，特别适用于开断感性负载产生的高频操作过电压的保护。
