Key Features
1. The device can run for a long time under the steady state overvoltage of 1.1 times the rated operating voltage;
2. The device can run continuously under the overcurrent of the capacitor bank whose root value does not exceed 1.3 times the rated current of the capacitor bank;
3. The device uses vacuum contactor to cut, which can be operated frequently;
4. Each set of capacitors is provided with a discharge coil, which can drop the remaining voltage to 50V or less within 5 seconds;
5. Each group of capacitors can be protected by relay or microcomputer protection control unit to achieve overcurrent, voltage imbalance, undervoltage and overvoltage protection of the capacitor bank. When a group of capacitors has a fault, it can cut off this group of capacitors without affecting the use of other capacitors;
6. Single capacitor has spray type fuse protection, each group is equipped with lightning arrester operating overvoltage and lightning strike overvoltage protection.
Applications
Power Systems
They are applied in substations at voltages of 35kV, 110kV, 220kV, 500kV, and 750kV to manage the reactive power in the main grid.
Industrial & Mining Enterprises
The devices are employed in industrial power distribution stations (e.g., 6kV, 10kV) to ensure efficient operation of heavy loads and complex machinery.
Distribution Networks
TBB devices are used in newly built and renovated power distribution networks to maintain stable voltage and optimize reactive power flow.
Voltage Quality Improvement
By controlling the operation of capacitors, the devices improve the quality of the power supply voltage, preventing issues like voltage sags and swells.
