摘　　要：特高压断路器开断试验方法的研究是特高压输电技术发展需要解决的关键问题之一。根据开断过程中的电弧特性,基于Mayr电弧方程理论,建立参数化的PSCAD电弧电阻模型,通过对几种适用于特高压断路器开断试验的合成回路进行系统仿真分析,模拟了直接试验回路、Hitachi四参数试验回路和ABB的EPIC试验回路的开断过程,以直接试验回路为基准,对Hitachi回路和EPIC回路开断前后的电弧过程和恢复电压进行了比较。It is a key problem to research the high power interrupting performance test method of ultra-high-voltage circuit breakers for UHV transmission technology development. Several synthetic test circuits for UHV circuit breakers are simulated in this paper. Firstly, the interrupting arc burning physics is analyzed. Based on the Mayr arc equation, the arc resistance model used in PSCAD simulation is fabricated. Employed this arc resistance model, the circuit breaker interrupting performance of the direct test circuit, the Hitashi four-parameter synthetic test circuit and the EPIC circuit proposed by ABB are simulated. The arc process and transient recovery voltage are compared.
