摘　　要：瞬态恢复电压的幅值和上升率是断路器开断的重要影响因素,文中以特高压示范工程项目为背景,利用电磁仿真软件EMTP-ATP研究在不同故障类型和不同故障位置情况下,线路间的感应电压对断路器瞬态恢复电压参数的影响。仿真结果表明:感应电压的存在使断路器瞬态恢复电压的幅值和上升率都超过了标准规定值,对断路器的开断能力提出新的考验,仿真结果对断路器结构设计具有一定的理论指导作用。The transient recovery voltage amplitude and its rising rate is an important breaking of circuit breaker. Based on the UI-IV demonstrative project as the background, factor influencing the the effect of induction voltage on transient recovery voltage parameter is researched under the condition of different fault types and different fault locations by using the electromagnetic simulation software EMTP-ATP. The simulation results show that the induced voltage makes the circuit breaker transient recovery voltage amplitude and rising rate go beyond the specified value in standard, which put new challenges to the breaking simulation results have certain theory guidance to structure design of circuit capacity of circuit breakers, and the breaker.
