Voltage transformers and lightning arresters for 220kV GIS
The 220kV GIS voltage transformer is a voltage conversion device used in GIS. Adopting fully enclosed high-voltage shielding, low loss and high saturation iron core, it has the characteristics of high measurement accuracy, small excitation loss, small volume, convenient installation, excellent sealing performance, stable and reliable performance, and free from operation and maintenance.
The 220kV GIS lightning arrester is a type of GIS used to limit overvoltage and protect power equipment. It uses high gradient oxide resistors and has the characteristics of large current capacity, low leakage current, low residual voltage, fast response speed, and small volume. The product is applied in the ± 800kV Suidong converter station of Southern Power Grid and the flexible direct converter station of State Grid Zhejiang Zhoushan.
