一种新型液态金属限流器限流特性的研究

In recent years a novel kind of liquid metal current limiter based on self-pinch effect was researched with its optimal and advantageous properties such as non-toxic, simple strcture, fast response, emission-free operation and a high number of short circuit interruptions. In this paper, the influences on the limiting property are researched from different factors such as prospective current, diameter of channels and their numbers. The experimental results indicate that the increasing prospective current and the smaller diameter of the channels could bring shorter pre-arcing time and higher arc voltage. Besides, the increase of the channels number hardly affect the pre-arcing time but could enhance the arc voltage partly. The research about the influence on the limiting property could guide the future design.
