摘要
Abstract
DC circuit breaker needs to be tested during the research process so to provide reference for the design and type test shall be performed for reliability verification after its manufacture.In this paper,the negative voltage coupling type hybrid DC circuit breaker at 15 kV is taken as an example to simulate its short circuit current interrup-tion process and extract the key electrical stress.The two-level voltage source synthetic test method is described,the two-level voltage source synthetic test circuit which is suitable for the negative-voltage coupling hybrid DC circuit breaker is designed and the parameter selection is optimized.The simulation results of test circuit with the electrical stress required in the interruption process are compared.It is proved that the two-level voltage source synthetic test method can provide the voltage and current stress required for the interruption process.Both equivalence and feasibil-ity of the two-level synthetic test method are verified.The results in this paper can provide reference for the research,design and experiment of HVDC circuit breaker.关键词
