Abstract

The invention provides a protective cover for knob disconnector. The protective cover comprises: a body, on which a receiving space for receiving the knob of the knob disconnector is provided, wherein the receiving space has an opening; and a lock piece, which is rotatably provided on the body, and which has a locking position for maintaining the knob within the receiving space and an unlocking position. By means of the body covering the outside of the knob, the protective cover of the invention can effectively prevent the operator from the risk due to accidentally touching the knob during the live working, thereby enabling the reparation of the knob disconnector to be performed even when it is energized, avoiding the loss caused by deenergization required for the reparation.

Description

technical field [0001] The invention relates to the field of electric power safety, in particular to a shielding cover for a porcelain pillar knife switch. Background technique [0002] In the prior art, when the load side line card of the disconnector ceramic column knife switch on the 10KV power distribution line processing column breaks or the lead wire falls off, the safety distance is not enough due to the small distance between the two ceramic columns , It will cause potential safety hazards to operators during live operation. Therefore, when repairing the load side line card or lead wire falling off, it is necessary to perform power outage treatment on the distribution line. Contents of the invention [0003] The present invention aims to provide a shielding cover for a porcelain pillar knife switch to solve the problem of potential safety hazards in the prior art when the porcelain pillar knife switch is charged. [0004] In order to achieve the above object, the ...
