自动跟踪补偿消弧装置的选择与应用

Selection and Application of Automatic Tracking Compensating Arc Extinguishing Device

自动跟踪补偿消弧装置能实时监测电网电容电流的大小,在正常运行时电抗值很大,相当于中性点不接地系统,在发生单相接地故障时能在极短时间内自动调节电抗值补偿电容电流,将接地故障电流限制在允许范围内,保证系统的可靠运行及人身和设备的安全。

The automatic tracking compensating arc extinguishing device can monitor high and low of capacitance current in electric network. When the devie is in normal operation,reactance valve is high,it is the equal of neutral point earth free system. When single--phase earth fault occurs,it can regulate reactance value automatically to compensate capacitance current, the earth fault current is limmnted within allowed band in order to ensure reliable operation of the system and safety of person and equipment.
