20KV Dry type Discharge coil for substation

Application 

This series of discharge coils are used to connect with high-voltage shunt capacitors in power systems, so that the remaining charge after the capacitor bank is removed from the power system is quickly released. Therefore, installation of discharge coils is a necessary technical safety measure for shunt capacitors in substation, which can effectively prevent the capacitor bank from closing again. The capacitor is still charged and the closing overvoltage and current endanger the safety of the equipment, and ensure the safety of the maintenance personnel. This series of products with secondary winding for line monitoring, measurement and secondary protection.

Structure and performance characteristics

1 The product adopts high quality epoxy resin system vacuum casting molding, oil-free, completely free from oil leakage, environmental pollution and flammable ect.
