Abstract: 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 analysis on electric arc energy in short-circuit breaking process, which provides help for optimal experiment flow when the relevant enterprise verifies let-through energy.
Key words: electric arc; residual-current circuit breaker; electric arc energy; closing angle; data acquisition system
