摘要
文章阐述了采用联合加压试验回路进行126kV及以上高压交流断路器失步开断试验的工作原理,计算了145kV电压等级失步开断试验回路的参数,对瞬态恢复电压波形进行了仿真,并依据此回路及试验参数进行了145kV/40k A失步开断(OP2)试验,试验结果符合预期要求。
This paper describes using the working principle which uses combined pressure test circuits for out-of-step breaking test of 126kV and above high voltage alternating-current circuit breaker to calculate parameters of out-of-step breaking test circuits in 145kV voltage grade and to simulates waveforms of the transient recovery voltage. 145kV/40kA out-of-step breaking (OP2) test has been done based on this circuit and testing parameters, and the test results confirm the anticipated requirements.
