Abstract

In high-voltage direct-current relays, transverse magnetic field is widely used to reduce the arc erosion. Experiments showed that re-strike phenomenon always occurred during the arc-blowing process, which increased the arc duration and affected the normal breaking operation. In this paper, the arc-blowing process is investigated for 300~800V, 50A resistive load and special attentions are paid on re-strike phenomenon. The re-strike type, re-strike voltage and re-strike probability under different voltages are studied with the help of the arc images and arc voltage waveforms.
横向磁场作用下高压直流分断过程中重击现象的实验研究
在高压直流继电器中,广泛采用横向磁场来减少电弧侵蚀。实验表明,吹弧过程中经常出现重击现象,增加了电弧持续时间,影响了正常的断弧操作。本文对300~800V、50A电阻性负载下的吹弧过程进行了研究,重点研究了重击现象。借助电弧图像和电弧电压波形,研究了不同电压下的重击类型、重击电压和重击概率。
