| 摘 要： | 用ATP仿真程序模拟了某断路器均压电容器正常操作时爆炸的过程以确定故障原因。断路器重燃过程和电容器击穿过程的模拟通过自动暂态控制开关(TACS)编程实现,3种故障原因的仿真波形图与故障录波图吻合,从而确定故障的真正原因是并联均压电容本身的绝缘缺陷未能承受正常的操作过电压而多次击穿。

| Abstract: | Aiming at the explosion accident of breaker grading capacitor in a substation under the normal operations, the method using ATP program to simulate this procession order to confirm the fault cause is presented. By programming based on the TACS, the simulation of the process of the breakers restrike and the process of the breakdown of capacitors is carried out. Three kinds of possible fault cause brought forward in the paper are simulated respectively, and the results which are consistent with recorded fault waveforms are obtained. Consequently the real reason of this accident is found. It is that the grading capacitors insulation had defect and it can not endure the normal switching overvohage. |
