- Commodity name: TBBZ High-voltage reactive power automatic compensation device
The TBBZ series high-voltage automatic reactive power compensation units, based on the grid and load conditions of 6 kV and 10 kV supply busbars, utilize a control system to automatically monitor and switch capacitor banks, thereby achieving automatic tracking and compensation of reactive power and ensuring a power factor of 0.9 or higher. This significantly optimizes power quality, reduces losses and energy consumption, and increases the transmission capacity of the power transmission and distribution system.
Overview
The TBBZ series high-voltage automatic reactive power compensation units, based on the grid and load conditions of 6 kV and 10 kV supply busbars, utilize a control system to automatically monitor and switch capacitor banks, thereby achieving automatic tracking and compensation of reactive power and ensuring a power factor of 0.9 or higher. This significantly optimizes power quality, reduces losses and energy consumption, and increases the transmission capacity of the power transmission and distribution system.
Model and Meaning
For example: TBBZ10-1500(600+900)-AK indicates a rated voltage of 10 kV, a compensation capacity of 1500 kVAr, with two automatically switched groups—one of 600 kVAr and the other of 900 kVAr—configured in a single-star connection, and equipped with open-delta voltage protection.
Operating Environment Conditions
◆ Altitude: not exceeding 1,000 m;
◆ Ambient temperature: -25°C to +55°C;
◆ Relative humidity: not exceeding 85%;
◆ The operating environment shall be free of explosive hazardous media; the surrounding atmosphere shall not contain corrosive or insulating-destructive gases or conductive media; and the space shall not be saturated with water vapor or harbor severe mold growth.Product Features
◆ The device can operate continuously under a steady-state overvoltage of 1.1 times the rated operating voltage;
◆ The device can operate continuously under an overcurrent not exceeding 1.3 times the rated current of the capacitor bank;
◆ The device employs vacuum contactors for switching, enabling frequent operation;
◆ Each capacitor bank is equipped with a discharge coil that reduces the residual voltage to below 50 V within 5 seconds;
◆ Each capacitor bank can be protected by relays or a microprocessor-based protection and control unit, providing overcurrent protection, voltage unbalance protection, undervoltage protection, and overvoltage protection for the capacitor bank. When a fault occurs in a particular capacitor bank, that bank can be disconnected without affecting the operation of the other banks.
◆ Each individual capacitor is protected by a rupture-type fuse, and each group is equipped with a surge arrester to provide protection against switching overvoltages and lightning-induced overvoltages.
◆ Large-screen LCD display controller that provides real-time monitoring of system voltage, current, and power factor; features an open communication interface and supports “four remote” functions.
◆ Each group can be equipped with reactors to suppress inrush currents during switching or to mitigate harmonic amplification.Main Technical Parameters
◆ Rated voltage: 6–10 kV;
◆ Rated frequency: 50 Hz;
◆ Rated capacity: 100–10,000 kVAr;
◆ Number of groups: 1–5;
◆ Reactor parameter selection: To suppress inrush current during switching, the reactance ratio shall be 0.1–1%; to suppress harmonics of the 5th order and above, the reactance ratio shall be 6%; to suppress harmonics of the 3rd order and above, the reactance ratio shall be 12%.
