The invention discloses a switch operating device. The switch operating device comprises an outer sleeve, an extension tube, an extension bar, a first regulating sleeve, a second regulating sleeve anda connector, wherein the upper end of the outer sleeve is of an opening structure, the lower end of the outer sleeve is of a closed opening structure, and the opening in the upper end of the outer sleeve and the closed opening in the lower end of the outer sleeve communicate with a first inner pipeline of the outer sleeve respectively; the extension tube sleeves the interior of the outer sleeve from the opening in the upper end of the outer sleeve in a penetrated manner; the extension tube is internally provided with a second pipeline, and the extension tube is of a structure which is closedat the upper end and is open at the lower end; the extension bar enters from the closed opening in the lower end of the outer sleeve, and sleeves the interior of the second pipeline of the extension tube from the opening in the lower end of the extension tube in the penetrated manner; the first regulating sleeve and the second regulating sleeve are arranged at the upper end and the lower end of the outer sleeve in a sleeving manner respectively; and the upper end of the extension tube and the lower end of the extension bar are fixedly connected with the connector matched with a functional matching tool respectively. The switch operating device is wide in length regulating range, the connector is matched with the functional matching tool through a polygon prism structure for efficient limiting, and the anti-rotation property is high.
Description
【Technical field】 [0001] The invention relates to the technical field of tools for power equipment maintenance, in particular to a switch operating device. 【Background technique】 [0002] The electric power industry is an important basic industry of the national economy, and safe, stable and sufficient power supply is the prerequisite for ensuring the healthy and stable development of the national economy. With the increasing expansion of the power grid and the increasing dependence of the social economy on electricity, the periodic maintenance of power equipment is also more frequent. During the maintenance process, the power supply personnel will change the state of electrical equipment according to needs. Electrical equipment is divided into operation, There are three states of standby (cold standby and hot standby) and maintenance. The process of changing the equipment from one state to another is called switching. The operation is called switching operation. By operatin...
