semi-enclosed dry discharge coil
This type of discharge coil is epoxy resin vacuum casting single phase.idoor fully encapsulated type product. It is applicable to be used for the power system with AC frequency 50Hz and rated voltage lOkV and below. It is connected with high voltage parallel connection capacitor group. When capacitor group cuts off from the system, it can take only five second to reduce the residual voltage of the capacitor group to safe voltage. When operating is normal, the secondary winding is used as voltage indicator. If users have special requirements, it can have relay protection action with residual voltage winding.
General:
It is an epoxy resin vacuum casting single-phase indoor semi-closed product, which is suitable for rated frequency 50Hz, rated voltage 10kv and below power system. Connect in parallel with the high voltage shunt capacitor resistance. When the capacitor bank is disconnected from the system, the remaining voltage on the capacitor bank is reduced to the safe voltage within 5s. During normal operation, the secondary winding can be used for voltage indication, and the residual voltage winding can be used for relay protection if the user has special requirements.
