TBBZ-12 high-voltage reactive power automatic compensation device

Product Introduction：

TBBZ-12 series high-voltage reactive power automatic compensation device can intelligently adjust the reactive power of 6KV or 10KV power supply bus. The device automatically controls the switching operation of the capacitor bank by monitoring the operation status and load changes of the power grid in real time, realizes dynamic reactive power compensation, and ensures that the power factor of the system is always above 0.9. This intelligent compensation technology can significantly improve the power quality of the grid, effectively reduce line losses, and improve the overall capacity utilization of the power transmission and distribution system

Key features:

1. High reliability operation: It can work stably for a long time at 1.1 times the rated voltage, and withstand continuous overcurrent operation of 1.3 times the rated current of the capacitor bank.
2. Intelligent switching control: The vacuum contactor is used for capacitor switching, which supports frequent operation and ensures rapid response to load changes.
3. Safe discharge design: Each group of capacitors is equipped with a discharge coil, which can reduce the residual voltage to below 50V within 5 seconds to ensure the safety of maintenance.
4. Multiple protection mechanism: support relay protection or microcomputer protection control, and realize protection functions such as overcurrent, voltage unbalance, undervoltage, and overvoltage. A single capacitor is protected by a spray-by-spray fuse, which is automatically isolated when it fails, and does not affect the operation of other groups. Each group is equipped with a lightning arrester to effectively protect against operating overvoltage and lightning overvoltage
5. Intelligent monitoring and communication screen: The wafer controller displays key parameters such as system voltage, current, and power factor in real time. Equipped with RS232/RS485 communication interface, it supports the functions of "four remotes" (telemetry, remote signaling, remote control, and remote adjustment), which is convenient for remote monitoring and management.
6. Harmonic suppression ability: optional distribution reactor can effectively suppress the closing inrush current or harmonic amplification, and improve the stability of the power grid. Through intelligent control and multiple protection design, the device ensures the efficient and safe operation of reactive power compensation, and is suitable for the optimization and energy-saving management of 6kV and 10kV power grids
