Abstract

The invention discloses a driving mechanism for an isolating switch, comprising a gear transmission assembly, a crank arm assembly and a mounting frame, wherein the gear transmission assembly is a vertical shaft bevel gear transmission assembly comprising a first bevel gear and a second bevel gear; the first bevel gear rotates around a first rotating shaft, and the second bevel gear is driven by the first bevel gear and rotates around a second rotating shaft; the first rotating shaft and the second rotating shaft are vertically arranged; the basic shape of the mounting frame is a rectangular framework formed by combining a front wall, a rear wall, a left wall and a right wall; the crank arm assembly comprises a supporting arm fixed on the second rotating shaft, a transmission arm used fordriving an externally connected operation spindle to rotate and a connecting arm used for connecting the supporting arm and the transmission arm; both ends of the connecting arm are respectively connected with the supporting arm and one end of the transmission arm; and when the first bevel gear rotates, the second bevel gear is driven to rotate so as to further drive the supporting arm to rotate,and the externally connected operation spindle is driven to rotate through the connecting arm and the transmission arm. The driving mechanism is suitable for a high-voltage switch cabinet and can effectively reduce the volume of the switch cabinet.

Description

technical field [0001] The invention belongs to the technical field of operating mechanisms of high-voltage electric appliances, and in particular relates to a driving mechanism used in high-voltage isolating switches. Background technique [0002] In the operating mechanism of the traditional isolating switch, the operating handle is generally set directly on the operating spindle, and the operating handle can be turned to drive the operating spindle to rotate to realize the circuit separation and closing; when the isolating switch is used in the switch cabinet, an operating handle can be used The lever is set on the operating spindle, and the operator stands in front of the switch cabinet and directly pulls the operating lever up and down to drive the operating spindle to rotate to realize the opening and closing operation. However, this driving mechanism has obvious disadvantages: one is that enough space needs to be reserved in the switch cabinet so that the operating ro...
