摘要
Abstract
A model was established using the PSCAD simulation software to analyze the variation laws of the circuit breaker's fracture recovery voltage and load capacitor plate voltage caused by restrike,non-sustained disruptive discharge(NSDD)and other factors after the circuit breaker interrupted single-phase and three-phase capacitive currents.Based on the simulation results,the test circuit was modified.Using the improved circuit,the capacitive breaking tests of the circuit breaker were conducted with the test of interrupting the rated cable charging current as an example.The test results were consistent with the simulation results.Meanwhile,combined with the latest provisions on class C2 circuit breakers in GB 1984-2024,some problems arising during the testing process of class C2 circuit breakers were discussed in detail.关键词
