CBB系列电力电容器充放电试验仪的研制

Study of CBB Series Electric Power Capacitor Charge- discharge Yest Instrument

CBB系列电力电容器在经过多次直流充电、短路放电试验后,进行电容器损耗角正切值(tanδ)测量及容量值测量,再根据其测量值变化情况,针对性的分析生产工艺中存在的问题。电容器短路放电电流很大,放电开关触点要求高,研制的CBB电容器充放电试验仪采用气缸驱动完成充放电动作切换,满足试验需要。

When DC charge and short circuit discharge of the cbb series electric power ca- pacitor is repetitiously experimentized.then testing dissipation tan6and testing capacity, have problem of produce technics is pertinently analyzed by the change of testing data.The cur- rent of capacitor short circuit discharge is big,contact of switch for discharge must durable. Study of CBB capacitor charge-discharge test Instrument, air cylinder drive for switch of charge-discharge is adopted,be equal to testing.
