TBBW low-voltage reactive automatic compensation device

The test,made by the Ministry of Power Industry Reactive Compensation Outfit Test Centre,confirmed that its various performance was up to the standard of JB7113-93 Low-voltage Shunt Capacitor Device.Besides, it passed the appraisal of Zhejiang Power Industry Bureau and was allowed by PICC. to cover quality reliability insurance of product. The product has passed the certification of ISO9001：2000 Quality System.

Brief Introduction：

The device adopts the latest microcomputer controller, which can fulfil balance throw/cut in an unique intellectual mode.It has the characteristics of complete functions, reliable safety,small volume,easy installation and repair.Applicable to transmission line of power system,it's a new generation of product to improve power factor,increase quality of power supply and save electricity.
    The device is divided into two kinds.Model No. TBBW is an intellectual reactive automatic compensation device, and Model No.TBBW2 is the one with control circuit of output switch.

Main characteristics:

1．The device has compact structure，small volume，good waterproof performance；internal running situation can be directly observed．

2．Adopts the latest microcomputerized-control and has stable performance，complete function，reliable running，correct measurement。Shift Can be made automatically or by hand at your will．

3．AdoptS unique intellectual balance throw-in and cut-off and can improve average use rate of capacitor

4．With our own product of BSMJ series self-healing shunted capacitor，it may effectively avoid leakage．

5．Adopts new-type shift contactor and may restrict inrush current to below 20In．

6．Has overvoltage protection function. In case a voltage of network exceeds 450 VAC and 1asts for 2 minutes，it can make capcitors automatically stop running in turn．when voltage recovers normal，the device will automatically recover normal running.
