Problems solved by technology

Under a certain breaking capacity, the operating mechanism is required to have higher opening and closing speeds and greater operating power to meet the requirements for vacuum circuit breakers in the power system, and this is often the case when the operating mechanism is large in size, The complex structure and bulky short board of vacuum circuit breakers also restrict the development of vacuum circuit breakers to large-capacity and high-voltage levels

The second magnetic drive mechanism is connected to the second movable electrode component and drives the second movable electrode component to realize connecting with or disconnecting from the first movable electrode component through relative movement.

Description

technical field [0001] The invention relates to a vacuum circuit breaker, in particular to a double-side breaking technology of the vacuum circuit breaker. Background technique [0002] Vacuum circuit breakers play an important role in control and protection in power transmission and distribution systems, and are widely used, especially in the field of medium voltage. The traditional vacuum circuit breaker is composed of conductive and arc extinguishing system, bellows, driving insulator and operating mechanism, etc. The main conductive circuit is composed of static conductive rod, static contact, moving contact and moving conductive rod in the vacuum bubble, through the bellows and The shell is sealed, and the outside of the vacuum bubble provides a leading circuit channel between the inside and the outside through a soft connection. When the vacuum circuit breaker is working, the static side parts are still, and the operating mechanism drives the conductive rod and the mo...
