AI Technical Summary
Technical Problem
Traditional disconnect switches use a rotary actuator, which is prone to slippage, resulting in low reliability.
Method used
It adopts a vertical push-pull structure, and the output shaft driven by the motor drives the vertical transmission rod to move up and down, so as to realize the closing or opening operation of the power arm and reduce the intermediate connecting rods.
Benefits of technology
The reliability of the disconnecting switch has been improved, the opening and closing time is controlled within 4 seconds, the transmission angle is 90 degrees, and it is suitable for the working conditions of railway catenary with high installation height.

Abstract
The utility model provides a railway overhead line system disconnecting switch side output transmission mechanism, which comprises a control box, a motor arranged in the control box and an output rotating shaft arranged outside the side wall of the control box, and is characterized in that the motor is used for driving the output rotating shaft to rotate so as to drive a vertical push-pull structure to move up and down so as to place a disconnecting switch at a closing or opening position; the vertical push-pull structure comprises a fixed mounting piece, a vertical transmission joint and a vertical transmission rod; the vertical transmission joints are arranged at intervals along the extension direction of the vertical transmission rod, and each vertical transmission joint is pivoted with the fixed mounting piece through a connecting rod; the upper end of the vertical transmission rod is pivoted with the lower end of the manipulator push-pull rod; the upper end of the manipulator push-pull rod is pivoted with the middle part of the electrified arm; one section of the electrifying arm is pivoted with the moving contact, and the other end of the electrifying arm is a free end; and the vertical transmission rod moves up and down along the vertical direction to pull or push the vertical transmission rod to drive the electrifying arm to swing around the pivoting position of the electrifying arm and the moving contact, so that the free end of the electrifying arm and the static contact are switched on.
