Application

This type of discharge coil is single-phase, cast resin insulated used in doors or outdoors connected with high voltage parallel connection capacitor group. When the capacitor group is cut off from the system, it can take only five second to reduce the residual voltage of the capacitor group from ?2Un to below 50V. When operating normal, the secondary winding is used as voltage indicator and the residual Winding is connected as split triangle. If the pole of capacitor partial breaks down, it would bring the zero sequence voltage to drive relay protection gear. The product is small, light, little ?partial discharge energy and high resistance to over voltage. It is a new product for superseding the oil type discharge coil.?


Code and implication


Structure

The discharge coil, is casting resin insulated and fully enclosed type. the discharge coil is dry type and porcelain insulated. The are made up of annular ?core. the primary winding and secondary winding are installed concentrically on the same iron-core pole. ?
