Abstract

The invention relates to an automatic switching transmission mechanism used for a small circuit-breaker and the small circuit-breaker. The automatic switching transmission mechanism comprises a transmission mechanism and handle components. The transmission mechanism is in linkage with the handle components. The transmission mechanism drives the handle components for closing operation. The transmission mechanism comprises double cams and a motor, and the motor is in transmission cooperation with the double cams. The double cams have a first position for level-one engaged transmission matching with the handle components and a second position for level-two engaged transmission matching with the handle components. The small circuit breaker comprises the automatic switching transmission mechanism, and can realize the function of automatic switching through the design of the double cams, division-level transmitting force, achieving greater force by smaller space. Due to the small size, the automatic switching transmission mechanism can be used in the small circuit breaker, realizes the automatic switching function of the small circuit breaker, and meets the national requirements for a smart grid and a smart city.

Description

technical field [0001] The invention relates to an automatic closing device for a switching device, in particular to an automatic closing transmission mechanism for a small circuit breaker and a small circuit breaker using the mechanism. Background technique [0002] For the power sector, the switch and breaker equipment is an essential equipment to ensure the safety of electricity consumption and to switch lines. With the country's requirements for smart grid smart cities, the development of low-voltage electrical appliances is promoted, especially in automatic closing, The development of functions such as self-testing and communication. [0003] However, due to the small space in the housing of the miniature circuit breaker, it is difficult to realize the function of automatic closing, which cannot meet the national requirements for smart grid smart cities. Therefore, it is urgent to develop an automatic closing transmission mechanism for miniature circuit breakers. Facil...
