Influencing Factors Analysis on Electric Arc Energy of Residual-Current Circuit Breaker

以漏电断路器作为对象,来研究分析短路分断产生的电弧问题,给出了电弧能量方程和电弧持续时间相关因素,通过改变短路电流、功率因数、合闸角度等条件,采用高速数据采集系统进行数据收集,对短路分断过程中的电弧能量进行数据解析,为相关企业进行允通能量验证时优化试验流程提供了帮助。

Taking the residual-current circuit breaker as the object, this paper studied and analyzed the electric arc problems caused by short-circuit breaking, giving the electric arc energy equation and the relevant factors of electric arc time of duration. Via changing the conditions such as short-circuit current, power factor and closing angle, the high speed data acquisition system was adopted to carry out data anal- ysis on electric arc energy in short-circuit breaking process, which provides help for optimal experiment flow when the relevant enterprise verifies let-through energy.
