Abstract

The invention discloses a reclosure transmission mechanism of a circuit breaker reclosure device. The reclosure transmission mechanism comprises a shell, a forward / reversing rotation motor arranged in the shell, a main shaft and a drive handle for driving a handle of a circuit breaker to conduct linkage. A transmission sheet and a transmission piece are arranged on the main shaft in a rotating mode. The forward / reversing rotation motor is matched with the transmission sheet in a drive linkage mode. A transmission gear with the main shaft as the rotating center is arranged on the transmission piece. A handle gear meshed with the transmission gear in a transmission mode is arranged on the drive handle. The outer surface, corresponding to the transmission piece, of the transmission sheet is provided with an arc-shaped groove. The transmission sheet and the transmission piece are in linkage with each other in the anti-clockwise direction and freely matched with each other in the clockwise direction. The reclosure transmission mechanism has the advantages that a match structure of a linkage shaft and the arc-shaped shaft is adopted, the contact resistance of the linkage shaft and the arc-shaped groove is small, and reclosing operation of the handle of the circuit breaker can be achieved without affecting the response time of normal trip of the circuit breaker.

Description

technical field

[0001] The invention relates to a reclosing device of a circuit breaker, in particular to a reclosing transmission mechanism of the reclosing device of a circuit breaker. Background technique

[0002] With the development of my country's smart grid, under the premise of requiring the grid to operate safely, it is urgent to control electrical appliances intelligently. For example, the combined use of prepaid energy meters and prepaid miniature circuit breakers (such as MM7S and MM10S series products produced by Zhejiang Mikeli Electric Co., Ltd.) can allow electricity users to automatically cut off the power supply when the prepaid electricity fee is exhausted. This greatly facilitates the distribution and control of electric energy by the power supply unit. However, after the user renews the fee, the user's circuit breaker cannot be automatically closed in time, and the user or the power supply staff need to manually operate, which brings inconvenience to th...
