Device Introduction
B Intelligent reactive power compensation device is carefully developed and designed to meet the needs of reactive power compensation for high-voltage lines. It is an automatic control device realized by microcomputer technology. The control device effectively and reasonably controls the switching of the parallel capacitor bank to improve power factor, reduce line loss, and improve voltage quality.
B The intelligent reactive power compensation device can control the switching of one or two parallel capacitor compensation devices according to the line voltage and line current, and at the same time, it can protect the capacitors according to the capacitor current and line voltage. This device has multiple sets of built-in control strategies, and the control strategy can be selected remotely and the control settings modified. It has R, radio frequency and other communication methods to choose from.
The wireless data communication of B intelligent reactive power compensation device uses the latest R mobile communication technology and mobile communication network as the transmission medium, taking advantage of R's high resource utilization, high transmission rate, short access time and other characteristics as the device. Data transmission channel with the dispatching master station.
