The FDME type discharge coil is used in AC 50Hz, 6-35kV power systems, connected in parallel with a high-voltage parallel capacitor bank, so that the residual charge of the capacitor after being cut off from the power system can be quickly discharged, and the residual voltage of the capacitor reaches the required value within the specified time.
This type of discharge coil has a secondary, rated voltage of 100V, and is used for relay protection.

structural characteristics
The FDME discharge coil adopts a fully sealed horizontal structure with reliable sealing performance, ensuring complete isolation between the insulating oil and the outside air. Its compensation method does not use an oil storage tank, but adopts an advanced structural compensation device. During operation, the discharge coil maintains a slight positive pressure inside the box (maximum<0.01Mpa, minimum>0.001Mpa). The sealing performance of each part is good, ensuring no oil leakage. It is a maintenance free product that does not require maintenance or replacement of components during its expected lifespan. The entire structure is reasonable, with excellent performance, small size, and beautiful appearance, making it your ideal choice.
