【摘要】 作为开断电流并隔离电网故障部分的保护设备,高压直流断路器对于未来的多端高压直流输电电网的发展尤为重要,高压直流断路器的开断可靠性需要通过试验验证。综述介绍了目前主要研制的高压直流断路器的基本拓扑结构,列出高压直流断路器的开断试验方法,分析了交流单频振荡法、电感储能直接试验法和短路发电机直接试验法以及合成试验法的原理及各自特点,提出了短路发电机直接试验法与合成试验法两种高压直流断路器开断试验方法为主要发展方向。更多还原

【Abstract】 For breaking short-circuit current and isolating the fault parts of the power grid,HVDC circuit breakersare very important for the future multi-terminal HVDC power grids,so the performance of DC circuit breakers mustbe verified to ensure the reliability. This paper introduces the basic topology of HVDC circuit breaker,points out themain test methods and illustrates the principle and characteristics of AC single frequency vibration method,directtest method of inductance energy storage,direct test method of short circuit generator and synthesis test method. Andthen this paper proposes that the direct test method of short circuit generator and the synthesis experiment are themain development direction of HVDC circuit breaker breaking test.更多还原
