Operating Mechanism Isolation Switch Fork Wheel Device and Operating Method

Abstract

The invention relates to a shift fork wheel device of a disconnecting switch of an operating mechanism and an operating method of the shift fork wheel device. The shift fork wheel device is designed to solve the technical problem that existing similar products easily produce load counter force. A support of the shift fork wheel device is provided with a motor and a second rotating shaft, and a first rotating shaft penetrates through a clamp plate of the operating mechanism to be connected with the output end of the operating mechanism. The shift fork wheel device is characterized in that an output shaft of the motor is in transmission connection with the first rotating shaft through gears and the second rotating shaft, the first rotating shaft is provided with a shift fork wheel, the two ends of a short arc edge on one side of the shift fork wheel are respectively provided with a convex arc lug in the outside diameter direction, idler wheels on the arc lugs are arranged in the shift fork wheel through idler wheel riveting pins, the output shaft is provided with a grooved pulley which is provided with a first groove and a second groove, one idler wheel of the shift fork wheel is matched with one groove of the grooved pulley, both the first groove and the second groove are slide way grooves, one end of each groove is opened in the edge of the grooved pulley, and the other end of each groove is in a semi-arc shape. The shift fork wheel device is suitable for being used as the disconnecting switch of the operating mechanism.

Description

technical field [0001] The invention relates to a high-voltage switch operating mechanism, in particular to a fork wheel device for isolating a switch of the operating mechanism and an operating method thereof. Background technique [0002] The isolating switch in the operating mechanism of the high-voltage switch is an important switching device for the power system to realize switching and switching circuits. However, the common problem at present is that the isolation position of this type of isolation switch cannot achieve accurate mechanical limit, which is easy to cause misalignment of the position, resulting in unpredictable changes in the isolation to the closing or grounding position. The overhaul and daily maintenance bring potential safety hazards. At the same time, the isolating switches of some existing high-voltage switch operating mechanisms still have problems such as complex groove wheel structure design, high processing cost, and low service life; Rotatio...
