XSG Low-Voltage Reactive Power Compensation Device

Product Description

　　The XSG low-voltage reactive power compensation device is a typical Flexible AC Transmission System (FACTS). Based on the actual reactive power demand and capacitor group grouping method of the system, this device uses instantaneous reactive power theory, wavelet analysis, dynamic measurement and calculation, combined prediction and reasonable operation. Using high-power thyristors connected in anti-parallel to form an AC contactless switch or composite switch, it can quickly switch the multi-level capacitor groups at zero-crossing, achieving contactless, surge-free, and smooth switching. It rapidly changes its reactive power output to provide dynamic reactive power for the power system.

　　This product complies with GB/T15576-2020 "Low-voltage complete reactive power compensation device" national standard. It is mainly used in mechanical manufacturing, metallurgy, mining, coal chemical industry, waterworks, building materials, ports, electrified railways and other users who need reactive power compensation.

Technical Advantages

　　1. The cabinet adopts a general-purpose cabinet form, the frame is assembled with C-shaped steel, and the frame design is a natural ventilation form, so that the electrical components in the cabinet are sufficiently cooled during operation. The top cover of the cabinet can be removed when needed for easy installation of the main busbar on site. Lifting rings are installed at the four corners of the cabinet top for easy lifting and transportation.

　　2. This series of products can use electromechanical switches, composite switches, and semiconductor switches (thyristors) as capacitor switching devices. The switching process is spark-free, noise-free, current-free, and free from overvoltage, simple and reliable.

　　3. This product applies the invention patent technologies of SHARESUN Electric's independently developed "Capacitor Compensation Contactor Upper and Lower Connection Structure" and "A Capacitor Compensation Dedicated Contactor", ensuring that the capacitor switching contactors will not overheat and burn out after multiple switchings and long-term operation.
