摘　　要：额定电流开断试验是考核交流接触器开断额定负载的能力,在开断瞬间交流接触器的两端需要分别承受电源侧TRV和负载侧TRV的考核。依据国家标准(GB/T 14808-2016)对4种类别交流接触器额定电流开合试验的TRV参数要求,计算了满足额定电压3.6~12.0 kV交流接触器试验回路电源侧TRV和负载侧TRV调频装置的电气参数。最后,在PSCAD/EMTDC仿真软件中搭建了额定电压7.2 kV、额定开断电流4 kA的试验电路,验证了电源侧TRV和负载侧TRV的预期参数均满足标准要求。Rated current breaking test is to assess the ability of AC contactor to break rated load.At the moment of breaking,both ends of AC contactor need to bear the source side TRV and load side TRV respectively.According to the requirements of the national standard GB/T 14808-2016 for the TRV parameters of the rated current opening and closing test of four categories of AC contactors,the electrical parameters of the TRV frequency modulation device on the power side and on the load side meeting the test circuit of AC contactors with rated voltage of 3.6~12.0 kV are calculated in this paper.Finally,a test circuit with rated voltage of 7.2 kV and rated breaking current of 4 kA is built in PSCAD/EMTDC simulation software to verify that the prospective TRV parameters on power side and on load side meet the standard requirements.
