The Role of The Power Relay:
Power relays have the advantages of fast action, stable action, long life, and small size. Widely used in power protection, automation, motion, remote control, measurement, communication, and other equipment.
Principle of Power Relay:
The working principle of the power relay is that when a certain voltage or current is applied to both ends of the power relay coil, the magnetic flux generated by the coil passes through the working air gap of the iron core, yoke, armature, and magnetic circuit. Under the action of the magnetic field, the armature is attracted to the pole surface of the iron core, thereby pushing the normally closed contact of the contact to open, and the normally open contact to close; when the voltage or current at both ends of the coil is less than a certain value when the mechanical reaction force is greater than the electromagnetic attraction force, the armature returns to its initial state, the normally open contact is disconnected, and the normally closed contact is connected.
