A transmission structure, an operating mechanism and an integrated circuit breaker

Abstract

The invention relates to a transmission structure, an operating mechanism and an integrated circuit breaker. The integrated circuit breaker comprises a circuit breaker body, the operating mechanism and at least one switch, wherein the operating mechanism comprises a motor and at least one transmission structure driven by the motor; the transmission structure comprises a circuit breaker main shaft; the transmission structure comprises a driving gear which is driven to rotate by the circuit breaker main shaft, a driven gear which is in meshing transmission with the driving gear, and an L-shaped driven shaft of which a front end is connected with the driven gear and a back end is used for driving the switch on the circuit breaker to be switched on or off; and the driving gear is a gear with incomplete teeth. Separate control of a plurality of sets of switches is finished through one set of operating mechanism, so that a circuit breaker switch, a grounding switch and a disconnecting switch can be integrated without interference. Moreover, compared with a conventional way of separately controlling the plurality of sets of switches by a plurality of sets of operating systems, the integrated circuit breaker has the advantages of simple structure, reasonable arrangement, saving of space, lowering of cost and realization of integration and miniaturization of the circuit breaker.

Description

technical field [0001] The invention relates to a transmission structure, an operating mechanism and an integrated circuit breaker. Background technique [0002] Circuit breakers, also known as automatic air switches, refer to switching devices that can close, carry and break current under normal circuit conditions, and can close, carry and break current under abnormal circuit conditions within a specified time. The important control and protection equipment in the system, in the high-voltage field, generally requires the circuit breaker to open and close quickly to avoid the danger of arcing. With the development of circuit breakers, circuit breakers need to integrate more switching functions. For example, when the circuit breaker is overhauled, it is necessary to use an isolating switch to isolate the circuit breaker. The isolating switch works normally. At the same time, in order to prevent the outer shell of the circuit breaker from being charged, a grounding switch is ...
