Arc Separating Process Experiment Study in Low Voltage Circuit Breaker

摘要：

　　Weather the arc is separated by the deion plates or not will determine success or failure of interruption for current-limiting circuit breaker.So its important to investigate the separating condition of arc by the splitters.In this study the oscillating circuit is used as supply power.For circuit breaker with 250A frame size, different materials and numbers of splitters are tested in short current interrupting process.Experiment results verified the necessary condition of successful arc separating process.While the arc column voltage is higher than total voltage of separated arc, the arc will be possibly separated.With the increase of splitters number the required current is higher while the other parameters are constant.Larger number of splitters means higher corresponding arc voltage, which may more easily cause back strike.
