TBBZ High voltage reactive power automatic compensation device

Main purpose and scope of application
TBBZ series high-voltage reactive power automatic compensation device according to the power grid and load conditions of the 6kV, 10kV power supply bus, through the control system capacitor bank to automatically track switching, automatic reactive power tracking compensation, so that the power factor can reach 0.9 or more. Greatly optimize power quality, save loss and reduce consumption, and increase the transmission capacity of the power transmission and distribution system.
This product complies with: National Standard GB/T30841-2014 (our company is the main drafting unit of this standard).

Model and meaning

Working conditions
1. Altitude: ≤1000m;
2. Ambient temperature: -25~+55℃;
3. Relative humidity: ≤85%;
4. No explosive dangerous medium is allowed in the operating place, and the surrounding medium should not contain corrosion Gas and conductive media that damage insulation. It is not allowed to be filled with water vapor and have serious molds.
 
Main technical parameters
1. Rated voltage: 6-10kV;
2. Rated frequency: 50Hz;
3. Rated capacity: 100-10000kvar;
4. Number of groups: 1-5 groups;
5. Reactor parameter selection: suppression of closing inrush current, The reactance rate is 0.1-1%; the reactance rate is 6% and the reactance rate is 6%, and the reactance rate is 12%.

Product features
1. The device can operate for a long time under steady-state overvoltage of 1.1 times the rated working voltage;
2. The device can operate continuously under an overcurrent whose root mean square value does not exceed 1.3 times the rated current of the capacitor bank;
3. The device adopts a vacuum contactor Switching on and off, can be operated frequently;
4. Each group of capacitors is equipped with a discharge coil, which can reduce the residual voltage to below 50V within 5 seconds;
5. Each group of capacitors can be protected by a relay or a microcomputer protection control unit to realize the capacitor group Current, voltage unbalance, undervoltage and overvoltage protection of the system. When a certain group of capacitors fails, the group of capacitors can be cut off without affecting the use of other capacitors;
6. A single capacitor is protected by a spray-by-fuse fuse, and each group is equipped with lightning arrester overvoltage and lightning overvoltage protection;
7 , Large-screen LCD display controller, real-time display of system voltage, current, power factor; with RS232/RS485 standard communication interface, and can realize the "four remote" function;
8. Each group of reactors can be configured to suppress closing inrush current or suppress harmonics Wave amplification.
