1. To control the power factor and system voltage within the set range by automatically tracking the switching capacitance and high voltage compensation.
2. It can flexibly select and compensate various working modes by remote automatic selection switch.
3. It can real-time display the voltage,current,power factor,reactive power,capacitor switching status and alarm protection information of the low voltage side of the main transformer.
4. It can be divided into 8 groups with the maximum capacity of 1800kvar according to the total compensation capacity.Automatic cyclic switching,switch on first switch off first,to ensure that all the capacitors are in time average of usage,and the same capacitor bank in less than the discharge time is not put into use again.
Configuration & Working Principle
1. The device consists of high-voltage capacitor,vacuum contactor,voltage transformer,protective current transformer,control unit,arrester,outdoor drop-out fuse,outdoor current transformer and others.
2. Working principle:According to the real-time voltage and current of the circuit collected by the voltage transformer in the box and the current transformer outside the box,the DWK controller,after calculation and processing,sends the input or removal instruction to control the opening and closing action of the vacuum contactor,so as to the capacitor can be switched on and off.
