Description

Technical Field

[0001] The utility model relates to a novel vacuum circuit breaker. Background Art

[0002] A vacuum circuit breaker is a high-voltage switchgear that uses vacuum as an insulating and arc-extinguishing medium. Its advantages lie in its high circuit-breaking capacity, good arc-extinguishing performance, miniaturized design, and long electrical life. It is widely used in distribution networks. During the wiring process when many existing vacuum circuit breakers are installed in outdoor distribution networks, it is necessary to use insulating tape to separately bundle the incoming wires and outgoing wires of the vacuum arc extinguishing chamber and keep them at a certain distance, so as to prevent the incoming wires and outgoing wires from being blown together and causing a short circuit in strong winds outdoors. However, the insulating tape ages quickly in an outdoor environment exposed to the sun and rain, and needs to be replaced regularly, which is not convenient to use. Therefore, it is necessary to develop a new type of vacuum circuit breaker to solve the above problems. Utility Model Content
