intelligent capacitor specification

While microelectronic, digital control, communication and network technology developed quickly and widely applied, intelligent electric apparatus

also is researched deeply. Now the electric apparatus become the trend of intelligence, integration, networking, high reliability, practicability, maintenance,

energy saving, environment protection, and safety. JK series intelligent integrated power capacitor is researched as newest low voltage reactive power

compensating device just on basis of such intelligent technology. This product has passed the test of National Power Industry Reactive Power

Compensating Device Test and Inspection Center, is a new generation to save energy, less line loss, improve power factor and electric quality for 0.4kv

power network. The device consists of intelligent control unit, through zero switching circuit, line protection unit, low voltage power capacitor, constructed

as upper and downside split modules, upper part composed of intelligent monitor and control unit, switch, protection system and etc, downside part is

two pieces (Delta connection) or one piece of (Star connection) low voltage power capacitors. The device divided into two kinds of compensating modes:

simultaneous mode, respective mode, single device can be put into service, or more become compensating system, to realize locally, individually, or

centrally compensation function, furthermore it can meet with the requirement of mixed compensation for three-phase unbalanced load.

The device adopted some advanced technologies of through zero switching, monitoring, networking communication, automatic control and etc, it

replaced the old mechanical switching technology of contactor or electromechanical switch for traditional reactive power compensating device, the

traditional device is very big and heavy, our new device has higher efficiency, smaller size, lower power loss, low cost, more agile, easier maintenance

and repair, longer life, higher reliability, better meet with the requirement of modern intelligent power network.

This device also used in different switchgear panel, better than what those factories make it by themselves.
