低压断路器中电弧运动形态的观察

Observation of the Arc Movement in Low Voltage Circuit Breaker

低压断路器开断中电弧的运动影响断路器的开断性能。通过对电弧运动的观察有助于更好地理解电弧的原理及对断路器进行改进。本文介绍利用高速摄像机对低压断路器开断中的电弧进行观察,并拍摄到低压断路器背后转移中的电弧运动图像。

The performance of low voltage circuit breaker depends greatly on the movement of arc. Through observation of the arc movement, the principle of the arc can be understood better and performance of circuit breaker can be improved. In the paper, high speed camera is used to study the arc movement. The backcommutation arc image is observed for the first time in the country.
