Diamagnetic coil
Product Overview
The reverse-magnetic coil is a device used in the electric control of high-voltage switches and in electromechanical protection systems to rapidly separate the high-voltage switch’s spring-operated mechanism contacts. It is primarily employed in applications where motor-driven energy storage is used to close the switch, followed by opening via the reverse-magnetic coil. This device is indispensable for high-voltage switches in power generation and supply sectors and represents another next-generation product for such equipment.
Main Parameters
Rated Voltage: DC 24V
Rated current: 0.33 A
Rated power: 8W
Spring Force: ≥26 N (force at maximum compression stroke)
Structure
The demagnetizing coil consists of a magnetic yoke, moving and stationary iron cores, elastic retaining magnets, magnetic shunts, copper plates, a coil, springs, and other components.
Working Principle
When an external force compresses the spring in the repulsion coil until the moving and stationary iron cores make full contact, the magnetic flux lines of the strong magnet pass through the magnetic shunt plate, the yoke, and the moving and stationary iron cores, maintaining the attracted state. When a DC voltage opposite in polarity to the original magnetic field is applied to the coil, generating a magnetic field equal in magnitude to the original field, the spring force forcibly separates the moving and stationary iron cores, thereby actuating the controlled spring mechanism to open the circuit.
