Whole Sealed Discharge Coil

1. Application
Used in HV power system, the product is connected with HV shunt capacitors, and as the capacitors removed from the power system, the residual charge will be promptly released, which effectively prevents from the re-closing over-voltage and over-current endangering the safety of maintenance personnel, due to capacitor charge is still with the equipment.
2. Features:
The whole sealed structure, which isolates the insulating oil from the atmosphere, is maintenance –free. The products adopt advanced oil-injected technique, new dielectric medium, and have reliable capability. The product has outer dilation oil compensation construction, which makes the product full of insulating oil all the time when it is operating in various conditions, at the same time, it keeps the internal pressure equal to the pressure of outer atmosphere, keeps the pressure away from being excessive caused by the superabundant temperature. So it has the function of anti-explosion and anti-spark.
3. Main parameters:
☆ Rated primarily voltage:  3.81~40.5kV.
☆ Rated secondary voltage: 0.1kV
☆ Rated output: 50-100VA
☆ Rated frequency: 50/60Hz
4. Implementation of standards
JB/T 8970-1999 《Discharge coil used for HV shunt capacitor》
DL/T 653-1998 《Order technical conditions of discharge coil used for HV shunt capacitor》
5. Service condition:
☆The product can be used in door or outdoor.
