Description
The 7.2(12)kV Four Poles AC Vacuum Contactor (CKG3) is a robust and reliable electrical component designed for high-voltage applications. This contactor features a comprehensive assembly, including an electrical insulating frame, a metal base, a shaft, and a crank arm for efficient operation. The electromagnetic system incorporates a permanent magnet, power modules, auxiliary switches, and vacuum interrupters to ensure optimal performance and safety.
When control voltage is applied across the electromagnetic coil, the armature activates, causing the crank arm to rotate and open the main contact within the vacuum interrupter. This process is complemented by the auxiliary switch, which disconnects the power to the electromagnetic coil, transitioning the system into a permanent-magnet maintenance state. Upon interruption of the control circuit, the energy stored in the power module discharges to the electromagnetic coil for degaussing, allowing the main contact to open under the force of an opening spring. This mechanism ensures a seamless and efficient operation in various high-voltage environments.
