| 1250kV/4A Three sets of gas insulation test equipment have been successfully delivered and have been applied to Shenyang High Voltage Switch Factory of New Northeast Electric Company. WJQ Series SF6 Gas Test Transformer (1) Application: Used for indoor test of power frequency withstａnd voltage and partial discharge of GIS, GIL, insulating basin, insulating rod and other electrical products, and for field test of power frequency withstａnd voltage and partial discharge of high voltage electrical products such as GIS, GIL and high voltage lines. (2) Main performance characteristics 1. The equipment adopts SF6 gas insulation, which has strong insulation performance and small volume. 2. Reliable operation and small partial discharge of equipment. 3. No special test shielding hall is needed, and the space is small. 4. Temperature rise: 1 hour running under rated current, temperature rise not higher than 65K (50Hz) control, high degree of automation of measuring device, double insurance control function of manual/automatic control, strong anti-interference, good stability and so on. (3) The control software has great expansibility and powerful programming and communication ability.
