Embodiment Construction

[0069] In the circuit breaking mechanism and the circuit breaker including the circuit breaker of the present invention, in addition to the movable parts, the mechanism casing can also move, thereby increasing the operating dimension of the circuit breaking mechanism and improving its flexibility. In addition, a reset component is added to the breaking mechanism, which does not move with the movement of the mechanism casing and the action component, so that when the breaking mechanism is in the second state and the mechanism casing is switched to the opening position, the reset action components to the closing position, thereby avoiding the fatigue loss caused by the action parts being in the opening position for a long time, and prolonging the service life.

[0070] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with ref...

Abstract

The invention provides a circuit breaking mechanism and a circuit breaker applying the same. According to the circuit breaking mechanism, besides an action part can move, a mechanism shell can also move under the operation of external force, so the operation dimension of the circuit breaking mechanism is increased. Besides, a reset part is added and does not move along with the movement of the mechanism shell and the action part, so that the action part is reset to the closing position in the process that the circuit breaking mechanism is in the second state and the mechanism shell is switched to the opening position, fatigue loss caused by the fact that the action part is located at the opening position for a long time is avoided, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of power supply and distribution in the electric power industry, in particular to a circuit breaking mechanism and a circuit breaker using the circuit breaker. Background technique [0002] With the rapid development of industrialization and urbanization in our country, the power demand will continue to grow in a long period of time, and the task of power grid development is heavy. It is particularly urgent to develop a strong smart grid. At the same time, the smart grid is also moving towards ultra-high voltage and ultra-high voltage levels. Therefore, the research and development of matching high-performance and high-reliability circuit breakers can provide a strong technical guarantee for the safety and reliability of smart grid power supply. [0003] In the process of realizing the present invention, the applicant found that the circuit breaking mechanism in the traditional technology only realizes the ...
