脉冲高压线路保护研究

Research on the protection of pulse high-pressure line

论述了脉冲式高压线路保护的基本原理以及基于该原理的保护装置的实现方法.该保护具有事故选线、事故选相功能、故障测距功能和自动重合闸功能.适用于各种电压等级的高压输电线路,在线路带电或不带电情况下均能对事故进行灵敏可靠检测.

The principle of high-pressure line protecting and realized means of protector are described. The means has many functions, such as selecting line or phase when accident, testing distance from malfunction,pulling switch automatically, etc. It can be used to all level of high-pressure line. Accidents can be checked sensitively and reliably whatever the line has electricity or not.
