Electric operating mechanism of general circuit breaker

Abstract

The invention relates to a circuit breaker and especially relates to an electric operating mechanism of a general circuit breaker. The electric operating mechanism comprises a gear motor, an executionmechanism and a transmission mechanism, wherein the execution mechanism is connected with a closing push rod; and the gear motor transmits torque through the transmission mechanism to drive the execution mechanism to act. According to the electric operating mechanism, when an electromagnetic clutch assembly is in a separated state, the closing push rod trips automatically, and since the electromagnetic clutch assembly is in the separated state, the closing push rod is not influenced by resistance of a shifter rod; and when the electromagnetic clutch assembly is in a connected state, the shifter fork can be controlled remotely to drive the closing push rod to move to an opening or closing position. The electric operating mechanism can independently control the opening and closing actions of the general circuit breaker while the tripping function of the general circuit breaker is not influenced, and has a fast opening function; and the whole electric operating mechanism is suitable fora plurality of models of circuit breakers, and is simple to operate and high in practicality.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to an electric operating mechanism of a general circuit breaker. Background technique [0002] In the prior art, according to the demand for intelligent power supply network in my country, the State Grid Corporation of China requires intelligent power supply network. The terminal of the existing power supply network must be installed with an executive mechanism - a circuit breaker, and when the circuit breaker receives an abnormal current signal, the circuit breaker has the functions of tripping and closing. At present, traditional circuit breakers only have the functions of manual opening and closing and overcurrent and overload automatic tripping, and there are defects such as relatively complex structure, easy failure and incomplete functions that cannot meet the needs of power companies; in the future development trend of circuit breakers, The circuit breaker should also have the function o...

Problems solved by technology

At present, traditional circuit breakers only have the functions of manual opening and closing and overcurrent and overload automatic tripping, and there are defects such as relatively complex structure, easy failure and incomplete functions that cannot meet the needs of power companies; in the future development trend of circuit breakers, The circuit breaker should also have the functions of electric opening and closing, remote control of the circuit breaker, real-time monitoring of electricity consumption, and collection of electricity consumption information, etc., so as to realize intelligent control of the circuit breaker, combined with smart meters and the State Grid, to realize arrears A series of operations such as automatic tripping and power off, charging and automatic closing and power transmission, and there is no such circuit breaking device on the market.
