A kind of wire temporarily fixed insulating operating rod

Abstract

The invention provides an insulating operating rod for temporarily fixing a wire, comprising: an insulating tube; a hook clip, which is arranged on one end of the insulating tube; a quick clamp assembly, which is sleeved on the insulating tube; The seat is sleeved on the insulating tube; the thrust bearing is fixedly installed on one side of the fixed seat of the rotating seat; the lower V-shaped rotating seat is fixedly connected with the thrust bearing on its flat surface; the fixture fixing seat is sleeved on the insulating tube; The middle of the clamp is rotatably connected with the clamp fixing base, so that the quick clamp can be rotated at the rotating connection point; the indenter fixing block is fixedly connected with the side of the quick clamp close to the insulating tube; The flat surface is fixedly connected with the side of the pressure head fixing block facing the insulating tube, and the upper V-shaped rotating pressure block is opposite to the V-shaped groove of the lower V-shaped rotating seat to form a clamping space. The present invention can effectively temporarily fix a large cross-sectional area of ​​a wire in the event of a wire breakage fault.

Description

technical field [0001] The invention relates to the field of live work safety construction, in particular to a wire temporary fixing insulating operating rod used in the field of live work safety construction of power distribution lines. Background technique [0002] When the high-voltage wire is broken, the ground point of the disconnected wire is the same as the potential of the live wire, and the current will flow from the ground point of the wire to the ground, so the ground is centered on the ground point of the disconnected wire, forming a potential distribution The farther away from the ground point, the more dispersed the current and the lower the ground potential. If the distance between people or livestock and the landing site is less than a safe distance, an electric shock accident may occur. Therefore, when a high-voltage wire is disconnected, the operator must use an insulating tool to temporarily fix the disconnected wire to ensure that the live body and the g...

Problems solved by technology

[0004] As the supply current increases, the cross section of the wire is also increasing. If the wire of the overhead line equipment is JKLYJ-120mm 2 Wires above, especially 150, 185mm 2 It is not easy to bend the wire to the main wire to bind and fix it, especially if the insulating operation rod is used, it will not work, which not only affects the safe construction, but also increases the risk of operation
