Abstract

The invention relates to the field of power system switchgear and specifically to a motor-operating mechanism capable of achieving wide-angle rotation angle output. The motor-operating mechanism comprises a support, a motor, a transmission mechanism, an output shaft, a stopping mechanism, an auxiliary switch change-over mechanism, an auxiliary switch, a contactor, and a box body. The transmission mechanism comprises a primary gear transmission mechanism, a worm gear and worm mechanism, a secondary driving gear, a releasing gear, and an output transmission mechanism which successively transmit rotary torque. The releasing gear is provided with a ratchet mechanism which controls an output rotation angle and a stopping releasing function by using a movable tooth-profile ratchet. A releasing gear transmission shaft is disposed in the support. The releasing gear is fixedly installed on the releasing gear transmission shaft. Both ends of the releasing gear transmission shaft are connected with the stopping mechanism and the auxiliary switch change-over mechanism respectively. The motor is driven to be started by the contactor and is driven to be stopped by the stopping mechanism. The motor-operating mechanism is small and reliable in overall structure and effectively controls the output rotation angle and stopping so as to prevent releasing.

Description

technical field [0001] The invention relates to the field of switchgear in a power system, in particular to a large-angle output motor operating mechanism capable of realizing large-angle output. Background technique [0002] At present, on the GIS switchgear of the power system, most of the operating mechanisms used by the isolation and grounding switches are rotary output, and the general output angle is less than 300 degrees. With the increase of the voltage level, the output angle required by the operating mechanism is getting larger and larger. For example, in the GIS switchgear above 550KV, the output angle is required to reach 700-3600 degrees. In order to meet the above requirements, the multi-stage gear combination transmission method is usually used in the prior art to realize the large-angle rotation angle output, such as the actuator produced by ABB company. The mechanism is the structure of multi-stage gear transmission plus clutch limit release. Due to the larg...
