高压断路器在运行中的问题分析

The Problem Analysis in the Operation of the High-Voltage Switch

高压断路器是电力系统不可缺少而使用广泛的电器，它是保证电力系统可靠运行的关键设备．由于电力系统的日益扩大，断路器在进行各种运行操作时会出现一些新问题，本文从理论上分析并联开断、近距故障开断和失步运行开断时的特点及可能产生延伸性故障的条件，说明提高断路器设计水平和加强断路器性能试验的重要性，使断路器的技术参数更为完善．

High-voltage switch is a kind of indispensable electric appliance which can be widely used in electric system.It is a key eguipment for ensuring reliable operation of electric system.As electric system is expanding increasingly,some problems may occur in the process of the various operation of the switches.This paper theoretically analysis the characteristic of the parallel breaking,short length fault breaking and out-of phase breaking and the condition of continual fault that can produce.It also explains the importance of improving the switch design and of reinforcing its performance test so that it can make the techmical parameter of the swich more Perfect.
