HLTBB (Z) -12kV capacitor automatic compensation device for indoor type, rated voltage 6~10kV, frequency 50Hz, rated voltage 6~10V for three-phase AC motor for reactive power compensation, reduce power loss and improve voltage quality and improve the starting performance of the motor. The capacitor compensation device in the input with the motor starting, stop removal. This is a compensation effect is much better than that of centralized compensation, such innovative products. The products are divided into simple type and vacuum contactor switched capacitor. A simple type of products through the fuse directly with the motor terminals connected, compensation device current does not exceed the no-load current of the motor 90% to avoid downtime self-excited motor produces overvoltage damage after compensation, the power factor may not be too high, generally around 0.9. The vacuum contactor switching, compensation capacity can be bigger, the compensated power factor was up to 0.95.

1 use conditions

Indoor use

Altitude does not exceed 2000m;

Ambient air temperature ~+40;

The installation site has no serious mold, no corrosive gas, no serious dust, no dust, no serious vibration.

Relative humidity: daily average of not more than 95%, the month is not more than 90%.

The device is only suitable for continuous operation of the motor, and no large impact load, and shall not be subjected to reverse or reverse connection of the motor can not be used in the speed control of the motor load.

2 selection mode

1 the rated voltage of the compensation device is in conformity with the system voltage.

2 the rated current of the simple product can not be greater than the no-load current of the motor 90%.

3 the calculation of compensation capacity: the calculation of the compensation capacity is the same as the low voltage reactive power automatic compensation device.
