FDGE9 type discharge coilDetailed product description：

The FDGE9 discharge coil is suitable for power systems with a rated frequency of 50Hz or 60Hz and a rated voltage of 10kV and below. It is connected in parallel with a high-voltage parallel capacitor bank. When the capacitor bank is disconnected from the system, it can reduce the remaining voltage on the capacitor bank to a safe voltage within 5 seconds. During normal operation, the secondary winding can serve as a voltage indicator. If the user has special requirements, the residual voltage winding can also be included to provide relay protection.
The product complies with the technical specifications for ordering discharge coils for voltage parallel capacitors (DL/T 653-1998).

Structure and Characteristics
This series of discharge coils adopts a pillar structure and is made of fully enclosed epoxy resin casting, which is resistant to pollution and moisture. It is also suitable for use in tropical regions. The transformer does not require special maintenance, only regular cleaning of surface dirt is needed. Install a wiring terminal box at the secondary output terminal of the transformer. There is a hole on the front and side of the terminal box to match the output terminal for safe and reliable wiring. There are grounding bolts and six mounting holes for installation on the product base plate.
