摘要

快速隔离开关是混合式直流断路器的关键部件之一。当开关时间在几毫秒以内时，常规断路器很难提供如此快的运行速度。本文在对真空开关进行研究的基础上，重点研究了小真空间隙在直流隔离、无弧分断情况下的应用，设计了一系列实验。在解决了每次开断的同步和电压分布问题后，研制了一种开断时间小于3ms的200kV直流快速隔离开关，并通过了直流断路器的整机试验。

Experimental Study on Fast Isolating Switch With Vacuum Multi-breaks

Fast isolating switch is one of the key components of Hybrid DC circuit breaker. It is difficult for conventional breakers to provide such a fast operating speed when the switching time is within a few milliseconds. In this paper, based on the study of the vacuum switch, focusing on the application of small vacuum gap in DC isolation, arcless breaking situation, a series of experiments were designed. After solving the problems of synchronous as well as voltage distribution in every break, a 200kV DC fast isolating switch with less than 3ms switching time is developed, And through the whole test of DC circuit breaker.
