Zhou Zhongsha · Insulators and Surge Arresters · 2014
The analysis of glowing and arcing discharge performance of surge protector is useful to solve the problems occurred in switching surge protector such as continuously flowing lightning current and delaying to release the current in order to select and take application of more reliable and safety surge protectors. Due to the difficult to capture the transient process of glowing and arcing discharge in surge protector, the analysis and experiment of glowing and arcing discharge performance are rare. In this paper,the theoretical analysis for the logical relationship among the parameters is firstly presented. Secondly a designed test circuit is used to measure the parameters and the experiment result includes glow discharging voltage,discharging duration,surge protective device switching time, glowing and arcing discharge lightning current capability and their relationship. Finally, the correctness of the theory and the effectiveness of experiment are verified by the PSPICE simulation software. The analysis and experiment mentioned in this article have provided a valuable reference for the designing and application of surge protectors.
