摘要

高压交流断路器的并联电抗器电流开合试验中

试验回路的预期TRV由负载侧参数决定

但在实际试验中电源侧参数对断路器断口间TRV也会产生一定影响

电源侧参数的合理选定是正确考核高压交流断路器开合并联电抗器性能的基础。针对一台145 kV的SF

断路器

利用PSCAD仿真软件

对比分析了不同电源侧电感、电容对TRV的影响。得出电源侧参数会导致TRV峰值和电压上升率不同程度增大的结论

其中电感值的增加会提升其增幅

电容值在一定范围内的增加会降低其增幅。进一步结合实际试验数据

验证了仿真分析结果。

Abstract

In shunt reactor current switching tests of high voltage alternating circuit-breakers

the prospective TRV parameters determined by the parameters of the load circuit. However

the TRV parameters between the gap of the circuit-breaker will be impacted by the parameters of the supply circuit in real tests. The rational method for determining parameters of the supply circuit is the foundation for correctly checking the performance of switching shunt reactor of high-voltage alternating circuit-breakers. For a SF

circuit-breaker of 145 kV

analyzed the different impacts on TRV caused by various inductance and capacitance of supply circuit by simulating with PSCAD software. Concluded that the para

meters of the supply circuit will lead to the increase of peak value and RRRV of TRV

the increase of the inductance will enhance the increase of TRV

the increase of the capacitance in a certain range will weaken the increase of TRV. Further combining the results of real tests demonstrated the results from the simulation.
