摘要
Abstract
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 pa-rameters of the rated current opening and closing test of four categories of AC contactors,the electrical pa-rameters 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 cir-cuit with rated voltage of 7.2 kV and rated breaking current of 4 kA is built in PSCAD/EMTDC simula-tion software to verify that the prospective TRV parameters on power side and on load side meet the stand-ard requirements.关键词
