Commutation Switch-Type Three-Phase Imbalance Governance Device
At present, there are a large number of single-phase, asymmetric, nonlinear and impact loads in the low-voltage distribution network system. The three-phase load system changes randomly. These loads will cause three-phase imbalance in the distribution system. The three-phase load imbalance will lead to the imbalance of three-phase voltage and current in the power supply system, causing negative sequence voltage and negative sequence current of the power grid, affecting the power supply quality, thus increasing line loss and reducing the power supply reliability. The commutation switch type three-phase load imbalance automatic adjustment device is a product specially developed for the above problems. It provides a perfect solution for solving the three-phase load imbalance in the distribution network. It is suitable for 380V/220V low-voltage distribution system of three-phase four-wire system. It can automatically and intelligently adjust the three-phase load with load without interrupting the power supply of users, thus overcoming the disadvantage of traditional manual line change to adjust the three-phase imbalance. And different from the compensation leveling methods such as SVG and interphase capacitors, HIEC HX realizes true three-phase balance from the "load side. The application of the automatic adjustment device for three-phase load imbalance in the distribution network will greatly improve the operation stability and intelligence of the distribution network, effectively reduce the transformer loss and line loss caused by the three-phase load imbalance, and solve the potential safety problems such as terminal low voltage and single-phase overcurrent caused by the three-phase load imbalance, which can play a good supporting role in the requirements of the power grid company for building a strong smart grid and improve the operation reliability of the low-voltage distribution network.
