A manual and automatic integrated intelligent electric operating mechanism for medium voltage isolating switch

Abstract

The invention relates to a medium-voltage disconnecting switch manual-automatic intelligent electric operating mechanism. The medium-voltage disconnecting switch manual-automatic intelligent electric operating mechanism comprises an operating handle, a leave-joint gear, a transmission gear, a third gear, a screw rod, a slider, a transmission rod and disconnecting switch operating rods. The operating handle is sleeved on a hexagonal shaft of the leave-joint gear, the leave-joint gear is sleeved on the transmission rod, the third gear is connected with the screw rod into a whole, the slider is provided with threads in the middle and sleeved with the screw rod, and the three disconnecting switch operating rods are arranged on the slider. The operating mechanism further comprises an intelligent control module, a motor, a transmission case, a first gear and a second gear. According to the medium-voltage disconnecting switch manual-automatic intelligent electric operating mechanism, manual and automatic free switching of a disconnecting switch can be achieved, the whole structure is small and exquisite, structure assembly is simple and flexible, the medium-voltage disconnecting switch manual-automatic intelligent electric operating mechanism can be conveniently matched with various types of medium-voltage disconnecting switches, and the whole configuration is flexible.

Description

technical field [0001] The invention relates to an electric operating mechanism of an isolating switch, in particular to an intelligent electric operating mechanism integrated with manual operation of a medium-voltage isolating switch. Background technique [0002] The operation of the existing medium-voltage isolating switch mainly relies on the crank arm and gear to be completed by manual operation. The overall structure is complex, and the operating mechanism can only be configured according to the model of the isolating switch. Moreover, it can only be completed by a single point and a single axis, which may cause problems such as three-phase asynchrony of the isolating switch; at the same time, due to the different operating forces of different personnel, faults such as contact heating caused by improper operation, or primary circuit faults may occur. The harm to on-site operators cannot be adapted to meet the needs of the existing development of security and smart grid...
