摘要

12 kV真空断路器投切并联电抗器时可能会产生合闸预击穿现象

形成危险的过电压。为探明合闸预击穿产生过电压的情况和改进现有合闸仿真模型。笔者在运行电网上对一种型号的12 kV真空断路器合闸并联电抗器进行了一系列的现场试验研究

并对合闸预击穿暂态过程和现象进行了分析。结果显示:该型号真空断路器的合闸预击穿率高达50%

且合闸预击穿相对地过电压均可超过4.0 p.u.。统计得到其合闸操作不同期特性、预击穿暂态过程中断口间介质动态绝缘强度恢复曲线和高频电流熄弧特性

并在ATP-EMTP中搭建真空断路器合闸预击穿MODEL控制模型。考虑电缆三相间的寄生参数

对该型号真空断路器合闸并联电抗器进行三相仿真计算

与试验结果对比分析显示

仿真结果与试验结果基本一致。

Abstract

Switching shunt reactors by 12 k V vacuum circuit breaker（VCB） may produce pre-strike phenomenon and cause severe overvoltage. In order to investigate the pre-strike overvoltage caused by VCB switching-in shunt reactors and to improve the existing simulation model

a series of field experiments of a type of 12 k V VCB are conducted on a running power system and the transient processes and phenomenon are analyzed. The results indicate that the pres-trike probability of this type of VCB is as high as 50%

and the phase to ground overvoltage caused by pre-strike can exceed 4.0 p.u.. A pre-strike model of 12 k V VCB switching-in shunt reactors is set up via ATP-EMTP based on the results of the field tests

including the switching-in operation characteristics of different period

the dielectric dynamic strength recovery curve and high-frequency current quenching characteristics. A three-phase simulation of the VCB switching-in shunt reactors in ATP-EMTP to simulate the field tests is established

and the cable parasitic parameters is considered in the simulation. The simulation results agree well with the experimental results.
