Application

TBBX type high voltage reactive local compensating device (hereinafter call compensating device) is of indoor use, for rated voltage 6-10KV, 50Hz, system to locally compensate reactive power for 6-10KV 3-P AC motor and to lessen the electric loss,  improve electric quality and motor starting performance, the compensating device will be switched on/off along with the motor on/off. The effect is better than the central compensation.

Model and implication

Working Conditions

     1.Indoor use
     2.Altitude not more than 1000m
     3.Ambient temperature: -10~ 40
     4.Mounting sites shall have no bacterium, corrosive gas, explosive particles, conductive dusts, and no severe vibration
     5.Relative humidity: daily average: < 95%, month average: < 90%
     6.This device is only suitable for continuous working motor that it has no severe fluctuated loading,  inverse rotation or inverse

        braking is forbidden, and it is not allowed to connect with speed adjustable motor.

     7.Rated voltage: 6-10KV
     8.Rated capacity as above sheet
     9.Rated current as above sheet
    10.Wiring mode: Y (star) connected, neutral line earthed

Structure

The enclosure of the device can be made of panel material or steel bent formation, the panel upper part is meter door, downward part is steel door, inside door is provided with safe lock, rear panel is left ventilating door which it is locked by spiral lock, at normal working, this do or is not allowed to open except that the power is out of supply

Selection

1.Rated voltage of the device shall be equal the system voltage
2.Rated voltage of the device shall be not bigger than motor no-loading current.
3.Calculation of compensated capacity:  as the methods of GGJ low voltage reactive auto compensation device.
