[0002] Vacuum circuit breakers utilize a vacuum state for arc extinguishing and insulation. They are used in industrial and mining enterprises, power plants, and substations to protect and control electrical equipment. Their basic structure consists of a vacuum interrupter (vacuum switch), an insulating bracket, and an operating mechanism. They are compact, lightweight, suitable for frequent operation, and arc extinguishing without maintenance, making them widely used in distribution networks.
