摘　　要：高压交流断路器的大容量试验是断路器产品开发和研制的重要环节。为满足GB 1984—2014《高压交流断路器》的要求,试验站需要确定试验回路的投切参数。通过计算单相试验容量为252 kV/63 kA的T100、T60、近区故障(L90)以及失步开断(OP2)4个试验方式的合成试验回路参数,利用Simulink搭建断路器合成试验回路模型,仿真并分析研究断路器在试验方式T100s(b)成功开断情况下的波形图,结果符合预期。此外仿真计算电压源过早投入和试品发生重击穿的情况,分析试验设备上出现的过电压,为试验设备的保护以及试验测量提供一定的参考依据。The large capacity test of high voltage AC circuit breaker is an important part of the development and research of circuit breaker products.In order to satisfy the requirements of GB 1984—2014“High Voltage AC Circuit Breaker”,the test station needs to determine the switching parameters of the test circuit.In this paper,the test loop parameters of four test modes of basic short circuit mode T100,T60,short-line fault(L90)and out-ofphase breaking(OP2)with single phase test capacity of 252 kV/40 kA are calculated.The Simulink software was used to build the circuit breaker synthetic test loop model,and the waveform diagram of the circuit breaker under the test mode T100s(b)was simulated and analyzed.The results were in line with expectations.Simulate the calculation of the premature input of the voltage source and the restrike of the test object,analyze the overvoltage appearing in the test equipment,and provide a reference for the test and the protection of the test equipment.
