Product details

■Product Introduction

The TBBZ series high-voltage reactive power automatic compensation device tracks the grid and load conditions of 6kV and 10kV power supply busbars. Through a control system, it automatically tracks the switching of capacitor banks to perform reactive power automatic tracking compensation, achieving a power factor of 0.9 or higher. It greatly optimizes power quality, saves energy and reduces losses, and increases the transmission capacity of the distribution system.

■Model Meaning

For example: TBBZ10-1500(600+900)-AK indicates a voltage of 10kV, a device capacity of 1500kvar, divided into two groups for automatic switching (one group of 600kvar, one group of 900kvar), star-type wiring, and open delta voltage protection.

■Product Features

• The device can operate long-term under a steady over-voltage of 1.1 times the rated working voltage;

• The device can operate continuously under an over-current with an RMS value not exceeding

• 1.3 times the rated current of t

• he capacitor bank;

• The device uses vacuum contactors for switching, allowing frequent operation;

• Each group of capacitors is equipped with a discharge coil, capable of reducing the residual voltage to below 50V within 5 seconds;

• Each capacitor can use relay protection or a microcomputer protection control unit to achieve over-current, voltage imbalance, system under-voltage, and over-voltage protection for the capacitor bank;

• When a fault occurs in a certain group of capacitors, it can cut off that group without affecting the use of other capacitors;

• Single capacitors are protected by spray-type fuses, and each group is equipped with a lightning arrester to provide over-voltage and lightning over-voltage protection during operation;

• Large screen LCD display controller, displaying system voltage, current, and power factor in real-time; features RS232/RS485 standard communication interface, and can realize "four-remote" (telemetry, remote signaling, remote control, remote regulation) functions;

• Each group can be equipped with a reactor to suppress inrush current during closing or suppress harmonic amplification.

■Operating Conditions

• Altitude: Not higher than 1000m;

• Ambient temperature: -25 ~ +55°C;

• Relative humidity: Not exceeding 85%;

• The operating location must not allow explosive hazardous media, the surrounding media must not contain corrosive and insulation-damaging gases and conductive media, and it is not allowed to be filled with water vapor or have severe mold.
