Reactive power dynamic tracking compensation device

　　The load of the AC power grid is generally inductive, which requires the power grid to provide reactive power. However, the reactive power delivered to the power grid by the generator is limited and cannot meet the reactive power demand of the electrical equipment. Therefore, it is necessary to supplement the power grid with reactive power to achieve a dynamic balance of reactive power, thereby improving the load power factor and achieving the purpose of saving electricity.

DQZ-04 reactive power dynamic tracking compensation device is an automated electrical device designed to maintain reactive power balance in local load areas. It uses photoelectric coupling technology and bidirectional thyristors as contactless power load switches to connect and disconnect capacitors. Since the input circuit and output circuit are completely isolated and there is no electrical coupling, it has strong anti-interference ability, high reliability, fast switching speed, no noise, no sparks, small size, long life, explosion-proof and vibration-resistant features, making this device superior in performance, complete in function, excellent in quality and reliable in operation.

The control circuit is based on a microcomputer, adopts fault-tolerant technology and software and hardware protection methods, and applies advanced technologies and methods such as zero-voltage switching, intelligent discharge, accurate phase shift, digital filtering, decoupling isolation and smooth drive, which completely overcomes the shortcomings of solid-state relays and thoroughly solves the shortcomings and defects of conventional resistance (or inductance) discharge methods.
