Embodiment Construction

[0028] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0029]An operating mechanism of a circuit breaker, comprising a spring energy storage device 1, a closing device 2 and an opening device 3, the spring energy storage device 1 is linked with the closing device 2, and the closing device 2 and the opening device 3 share an output shaft 5 is connected to the circuit breaker. When the closing operation is performed, the spring energy storage is released to drive the output shaft 5 to rotate in the closing direction, and at the same time, the opening torsion spring is used to store energy for the opening. When the opening operation is performed, the opening torsion spring Releasing the stored energy drives the output shaft 5 to rotate in the opening direction, thereby performing closing and opening operations on the circuit breaker respectively.

[0030] Such as image 3 As shown, the spring energy s...

Abstract

The invention provides a circuit breaker operating mechanism. The circuit breaker operating mechanism comprises a spring energy storage device, a closing device and a breaking device, wherein the spring energy storage device is linked with the closing device, and the closing device and the breaking device are connected to a circuit breaker by sharing an output shaft; during closing operation, spring stored energy is released and drives the output shaft to rotate towards a closing direction, and breaking energy storage is achieved by a breaking torsional spring; and during breaking operation, the stored energy is released by breaking torsional spring, the output shaft is driven to rotate towards a breaking direction, so that closing operation and breaking operation are performed on the circuit breaker. The circuit breaker operating mechanism is reasonable in structure, stable in performance and low in manufacturing cost, and the service lifetime of a product is substantially prolonged.

Description

technical field [0001] The invention relates to a circuit breaker operating mechanism for a switchgear. Background technique [0002] The function of the circuit breaker is reflected in that when its contacts are opened and closed, it can realize the disconnection and connection of the circuit, and the opening and closing actions of the circuit breaker are realized by the operating mechanism. [0003] For the switchgear, the performance of the current circuit breaker operating mechanism is unstable, it occupies a large space, and the manufacturing cost is high, so it is necessary to adjust the structure of the circuit breaker operating mechanism. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an operating mechanism of a circuit breaker, which has reasonable structure, stable performance and long service life. [0005] The technical solution adopted by the present invention to solve the technical problem is: a c...
