Abstract

The invention relates to a switch overshoot preventing device and a high-voltage switch using the device. The anti-overshoot device of the switch includes an input transmission part, an output transmission part and a clutch device between the input transmission part and the output transmission part. The trip pin at the opposite end, the trip pin is guided and assembled in the open slot, the sleeve is rotatably and axially locked on the connecting frame, and the output transmission part includes a wire that is connected to the output shaft in a non-rotational manner. The rod and the axially moving screw nut assembled on the lead screw. The connecting frame is provided with an opening stop structure and a closing stop structure respectively corresponding to the opening position and closing position of the switch. Between the brake stop structure and the closing stop structure, during the moving process, the nut part pushes the opening stop structure or the closing stop structure to make the release pin on the corresponding shaft escape from the open slot.

Description

technical field [0001] The invention relates to a switch overshoot prevention device and a high-voltage switch using the device. Background technique [0002] After the isolation / grounding switch of the high-voltage electrical appliance is in place, because the motor cannot stop immediately, the operating mechanism and transmission part of the high-voltage switch continue to operate, which will cause the product to open and close overshoot. If the opening and closing overshoot is large, it may cause product damage and affect the safe operation of the power grid. Therefore, it is necessary to use a device to prevent the overshoot of the switch opening and closing, so that the product can reliably stay in the opening and closing position after the action is in place, and avoid the overshoot of the product opening and closing due to the continuous rotation of the motor. [0003] The Chinese patent document with the announcement number CN2824260Y and the announcement date of Oc...
