  Bdkj-c filter compensation device Reactive power compensation box on high voltage column
 
Equipment introduction
  Bdkj-c is a device independently developed by Baoding Beidian Electric Technology Co
, Ltd
for reactive power compensation of 6-10KV transmission line
The equipment adopts microcomputer dynamic compensation controller with single chip microcomputer as the core, with strong anti-interference ability, accurate data acquisition, stable output and fast response speed; According to voltage, time, power factor, reactive power and other parameters, the switching of shunt capacitor can be controlled by automatic controller to improve line power factor, reduce line loss and improve voltage quality
It can automatically quit work in case of external failure or power failure, and automatically resume operation after power transmission without human intervention

Functional features:
1
The device mainly adopts single-chip microcomputer technology to collect and calculate the data of current, voltage, active power, reactive power and power factor of the line, control the switching of power capacitor by using the principle of regional control, realize the automatic compensation of reactive power, and adjust the power factor of the power grid to the optimal state

  2
The device supports centralized compensation of reactive power and local compensation of decentralized high-capacity load (such as high-power motor)
Users can flexibly configure centralized compensation equipment and local compensation equipment in the system according to the degree of load dispersion and concentration

3、  Improve power quality, reduce voltage fluctuation and improve voltage stability
The power factor can be increased to more than 0
95, reduce user line loss, improve the bearing efficiency of distribution transformer and obvious economic benefits

4、  High performance contactor and comprehensive protection control system are adopted to switch each compensation branch, so that the equipment operation is simple, safe and reliable

5
The device has overvoltage, undervoltage, harmonic, time limited quick break, overcurrent, unbalanced current, 10min protection and other microcomputer protection functions, which provides a strong guarantee for the reliable operation of the device

6
With standard RS485 communication interface, GPRS Remote Monitoring and wireless monitoring can be realized

7
The equipment has advanced technology, high reliability, small maintenance and durability
