Abstract
An electrically operated mechanism of a high voltage vacuum load switch mainly solves the problems that the existing product cannot realize remote control nor meet the automation need of power distribution, etc. The utility model comprises a mechanism case, a contactor, a thermo relay, an auxiliary switch and an operation button, etc., and is characterized in that the mechanism case is internally provided with a motor, an output shaft of the mechanism case is connected with an worm shaft through the auxiliary transmission of a reduction gear; a worm is engaged with a worm wheel which is fixedly connected with a main shaft, one end of which is fixedly connected with a yoke plate, which is connected with a switch gear connection component. The utility model has the advantages of realizing remote control, meeting the automation need of power distribution, no need of energy storage and short motion time, and the power supply can be 220V single-phase alternating current or direct current.
Description
Technical field
The utility model belongs to a kind of driving mechanism of high-pressure vacuum switch, and particularly a kind of high pressure vacuum is isolated the on-load switch motor drive mechanism.
Background technology
The existing high pressure vacuum of producing of China is isolated on-load switch and is had only man-operating mechanism, does not have motor drive mechanism, thereby exist can not far distance controlled, can not satisfy the requirement of power distribution automation.
The utility model content
The purpose of this utility model provides a kind of high pressure vacuum and isolates the on-load switch motor drive mechanism, can realize far distance controlled with electric control gear is supporting, can satisfy the requirement of power distribution automation, not need energy storage, operate time is short, can use 220V single-phase alternating current or direct current as power supply.
The purpose of this utility model is achieved in that it comprises mechanism case, contactor, thermal relay, auxiliary switch, control button etc., it is characterized in that: assembling motor in the mechanism case, the output shaft of motor is by speed reducing gear pair driving coupling worm shaft, the worm engaging turbine, the affixed main shaft of worm gear, the affixed yoke plate of main shaft one end, yoke plate connect the switch parts that are in transmission connection.
Operation principle: electronic separating brake: by pressing control button, the normally open contact closure of separating brake contactor, motor work, driving gear wheel set and worm gear reducer device drive main shaft and rotate, and by the action of yoke plate with the parts that are in transmission connection, make the switch separating brake.When main shaft rotated near the separating brake final position, the normally open contact of contactor was opened, and cut off motor power, and switch is limited in the accurate position of separating brake.Electric switch-on: by pressing control button, the normally open contact closure of closing contactor, motor work, driving gear wheel set and worm gear reducer device drive main shaft and press rightabout and rotate, and by the action of yoke plate with the parts that are in transmission connection, make the switch combined floodgate.When main shaft rotated near the combined floodgate final position, motor power was cut off in the closing contactor outage, and switch is limited in the accurate position of closing a floodgate.
The utility model has the advantages that: can realize far distance controlled with electric control gear is supporting, can satisfy the requirement of power distribution automation, not need energy storage, operate time is short, can use 220V single-phase alternating current or direct current as power supply.
