并联电容器设计应注意的问题

介绍了采用并联电容器进行无功补偿的三种方式推荐采用就地补偿,降低线路损耗,最大程度节约能源。介绍了电容器的接线方式6kV、10kV电容器采用星形接线,而低压电容器一般采用三角形接线。在并联电容器时串联电抗,抑制谐波及涌流,并且注意电容实际工作电压将大于其标称工作电压,以便合理选择电容器容量。

Attentionable Issues of Shunt Capacitor Design

Field compensation are suitable to reactive power compensation by shunt capacitor, which are helpful to low line loss and save energy. Capacitor connection type are following:6/10kV capacitor using star type and low-voltage capacitor using delta type. Series connection reactor are necessary for shunt capacitor when harmonics and rush current are need to restrain. Actual operating voltage of capacitor are greater than normal operating volotage in this case, which arising to greater capacitance volume.
