| 摘 要： | 分析了高压并联电容器在运行中发生箱壳爆裂的起因和必要条件,认为只有当具备电容器的内部发生贯穿性击穿、电容器接入处系统有足够大的短路容量或并联电容器容量足够大及故障电容器的端子与系统或与并联的完好电容器间具有1条低阻抗放电通道这3个条件时才会发生箱壳爆裂,提出了为防止高压并联电容器在运行中发生箱壳爆裂事故所应采取的对策和措施。

| Abstract: | In this paper,the origin and necessary conditions for case rupture of the high voltage shunt capacitors in operation are analyzed.It is thought that when only such three conditions as,Internal cross-cutting breakdown occurs through the capatitor,Has sufficient short circuit capacity at the joint point of the capacitor bank to system or sufficient capacity of shunt capacitor bank,A low resistance discharge channel is in essence between the terminal of failure capacitor and the system or other parallel normal... |
