Description

Technical Field

[0002] A moving contact without partial discharge refers to a contact element used in electrical equipment. It can generate dynamic contact when the power is turned on without human intervention. This contact is usually composed of an electromagnet, a spring and a contact. When the electromagnet is energized, the magnetic force generated will pull the spring to make the contacts contact, thereby completing the circuit closure. When the electromagnet is de-energized, the spring will return to its original state, the contacts will separate, and the circuit will open. During the operation of the moving contact, the temperature is monitored in real time to avoid accidents.
