Magnetic quenching of DC breaker, contactor and relay: When the switch contact breaks the current, the magnetic field generated by the sheet magnetic steel makes the arc move rapidly towards the arc extinguishing chamber under the action of electromagnetic repulsion force, rapidly elongate, cool and extinguish, and protect the contact from being burnt by the arc.
