Complete Product Introduction
1. Product Brief Introduction
The TBBZ series high-voltage reactive power automatic compensation device monitors the load and power grid conditions of 6kV and 10kV power supply lines, and automatically tracks and switches capacitors on and off through the control system to realize automatic tracking and compensation of reactive power, with a power factor reaching above 0.9. It greatly optimizes power quality, saves energy and reduces consumption, and improves the transmission capacity of the power distribution system.
2. Model Meaning & Explanation
The coding of the product model contains the core structural characteristics and parameter information of the compensation device. The specific meaning of each part of the model is as follows:
TBBZ □ - □ (□) (□□□)
Example: TBBZ-10-1500(600+900)-AK means the rated voltage is 10kV, the installed capacity is 1500kvar, with two groups of automatic switching (one group is 600kvar, the other is 900kvar), single-star wiring, and open delta voltage protection.
3. Normal Operating Conditions
- Altitude: not higher than 1000m;
- Ambient temperature: -25 ~ +55℃;
- Relative humidity: not exceeding 85%;
- The operation site shall not contain dangerous media; the surrounding medium shall not contain corrosive and insulation-damaging gases and conductive media, and shall not be filled with water vapor and serious mold.
4. Product Characteristics
- 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 of 1.3 times the rated current of the capacitor bank at the peak value;
- The device adopts vacuum contactors, which can be operated frequently;
- Each capacitor bank is equipped with a discharge coil, which can reduce the residual voltage to below 50V within 5 seconds;
- Each capacitor bank can use relay protection or microcomputer protection control unit to realize overcurrent, voltage unbalance, system undervoltage and overvoltage protection of the capacitor bank. When a fault occurs in a certain group of capacitors, the group of capacitors can be cut off without affecting the use of other capacitor banks;
- Single capacitors are equipped with expulsion type fuses, and each is equipped with a surge arrester for overvoltage and lightning overvoltage protection;
- Large-screen LCD display controller, real-time display of system voltage, current, power factor; with RS232 / RS485 communication interface, and can realize the "four remote" functions;
- Each group is equipped with a reactor to suppress closing inrush current or inhibit harmonic amplification.
