First, the use of
This type of discharge coil for AC 50Hz, 6 ~ 10kV power system, connected with the high voltage shunt capacitors in parallel to the capacitor from the residual charge of power system after resection of fast discharge, residual voltage of a capacitor within the specified time to reach the desired value.
This type of discharge coil two winding can be used as a protection device for electric appliance. 

Two, structural characteristics
This type of discharge coil is a resin casting dry device. The coil and the iron core are integrally cast by the resin, and the inner and the outer insulation are enhanced. The discharge coil is divided into indoor and outdoor two, indoor type high quality indoor full resin casting, outdoor outdoor imported resin pouring from the whole. The discharge coil has the advantages of compact structure, small volume, light weight, good insulation, no oil leakage and leakage.

Three, the use of environmental conditions
1, installation location: outdoor or indoor
2, outdoor environment temperature: -40 to +40 DEG C, indoor -5 to +40 DEG C
3, altitude: not more than 2000M
4, anti pollution capacity: external insulation to climb than the distance of not less than 25mm/kV.
5, the installation site of non corrosive gas, steam, no conductive or explosive dust.
6, the installation place no severe mechanical vibration.
7, maximum wind speed: 35m/s
