Abstract

The reignition of the arc during the interruption process deteriorates the switching performance of low-voltage switching devices (LVSDs). Avoiding reignition is thus a key goal in the effective design of the quenching chamber. A reliable evaluator of reignition provides the opportunity to predict the switching performance of an LVSD during the design process and to refine the product prior to manufacture and empirical device testing. In this paper, reignition evaluators are investigated through the analysis of interruption test data for several types of LVSDs under the single-phase and three-phase circuit conditions. It is observed that the ratio of the recovery voltage to exit arc voltage, where exit arc voltage is defined as the value of the arc voltage immediately prior to the current zero point, is a reliable evaluator for the prediction of reignition in the switching tests of LVSDs. It is also noted that there are no occurrences of instantaneous reignition where this voltage ratio lies in the range from 1 to -1, and there is a threshold of the voltage ratio at approximately -2, which can distinguish the successful interruption and instantaneous reignition.
