Summary

The TBBZ series high-voltage reactive automatic compensation device automatically tracks and switches capacitor banks through the control system according to the grid and load conditions of 6KV and 10KV supply busbars, thereby

automatically tracking reactive power compensation and achieving a power factor of over 0.9. It greatly optimizes power quality, saves energy, reduces consumption, and increases the transmission capacity of the power distribution system.

 Use environmental conditions

◆ Altitude: not high 1000m;

◆ Ambient temperature: -25~+55℃:

◆ Relative humidity: not more than 85%:

Product features

 The device can operate for a long time under the steady-state overvoltage of 1.1 times the rated working voltage:

◆ The device can operate continuously under the overcurrent condition where the root mean square value does not exceed 1.3 times the rated current of the capacitor group:

◆ The device adopts vacuum contactor switching, which can be operated frequently;

◆ Each capacitor group is equipped with a discharge coil, which can reduce the residual voltage to less than 50V within 5 seconds;

◆ Each capacitor bank can be protected by a relay or a microcomputer protection control unit to realize overcurrent, voltage imbalance, system undervoltage and overvoltage protection of the capacitor bank. When a fault occurs in a certain capacitor bank, the capacitor bank can be cut off without affecting the use of other capacitors:

◆ Each capacitor is protected by a jet fuse, and each group is equipped with a lightning arrester to protect against overvoltage and overvoltage due to lightning:

◆ Large screen LCD display controller, real-time display of system voltage, current and power factor; has RS232/RS485 standard communication interface, and can realize the "four remote" function:

◆ Each group can be equipped with reactor to suppress the inrush current or harmonic amplification.
