FULLY-ENCLOSED DRY DISCHARGE COIL

Product overview

This type of discharge coil is epoxy resin vacuum casting single phase，idoor semi encapsulated type product.It is applicable to be used for the power system with AC frequency 50Hz and rated voltage 10kV 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.
