Study on Explosion-proof Structure and Reliability for Self-healing Low Voltage Shunt Capacitor

自愈式低压并联电力电容器的防爆可靠性是低压电容器质量和安全的重要指标之一,本文通过熔丝防爆、过温保护和过压力保护等不同防爆结构对自愈式低压电容器质量的影响分析,从实际应用经验和实验数据分析各自的局限性,提出点焊插入式电容器防爆装置的可行性。

The explosion-proof reliability of self-healing type low voltage shunt power capacitor is one of important indexes for quality and safety of low voltage capacitor. In this paper, throughout analysis of the influences such as ： different explosion-proof structures, fuse explosion-proof, over temperature protection and over pressure protection etc., on quality of self-healing low voltage capacitor, from practical experience and experiment data, respective limitations are analyzed, and feasibility explosion-proof device of spot welding capacitor is proposed.
