Integral insulating shield for simultaneously shielding concrete pole shafts and single crossarms

Abstract

The present invention discloses an integrated insulating protecting cover covering both a cement rod body and a single cross arm. The integrated insulating protecting cover comprises an electric rod body covering part (1) and a cross arm covering part (2) that are made of insulating rubber. The electric rod body covering part (1) comprises an upper electric rod body covering part and a lower electric rod body covering part, a rod body and a covering part at the connection part of the cross arm, and is a cylinder formed by rectangular insulating rubber boards. The cross arm covering part (2) is formed by inverted L-shaped left and right cross arm covering parts. A lapping part is provided with a magic tape lapping two sides of the lapping part. Left and right covering connection parts are connected with a groove of a connecting part covering part (13) of the rod body and the cross arm. The connection part of the left and right covering connection parts and the electric rod body covering part (1) is provided with a chamfered edge. The left and right cross arm covering parts are folded upward so as to seal an opening (5). The integrated insulating protecting cover has a simple structure, is safe, stable and reliable, is flexible in adjustment, can be widely used, improves efficiency of hot-line work, ensures security of the hot-wire work, improves insulation covering efficiency, and reduces labor intensity.

Description

Technical field: [0001] The invention relates to an insulating shield for simultaneously shielding a cement pole shaft and a single cross arm. It is widely used in the live replacement of drop-out fuses, linear pole insulators, and tensile insulators on overhead distribution lines, and belongs to live maintenance field technology field. Background technique: [0002] Live work on overhead power distribution lines can not only avoid power outages for users, but also work time is more flexible. With the continuous improvement of social and economic requirements for power supply reliability, the projects and scope of live work on power distribution lines are expanding year by year. Due to long-term operation of overhead power distribution lines, equipment components are bound to age. In the live replacement of drop-out fuses, linear pole insulators, tensile insulators, etc., it is necessary to insulate and shield the pole shafts and crosspieces that may be touched within the workin...

AI Technical Summary

Problems solved by technology

Both of these methods require the use of insulating blankets to shield the connection between the pole shaft and the cross-arm. Due to the irregular shape of the connection between the pole shaft and the cross-arm, it takes a lot of time after the insulation blanket is covered, and the shielding is not firm and tight. , Workers' physical exertion, etc.

Moreover, because the shielding of the ground potential object is not firm and tight, when the operator moves the charged body, it is prone to the danger of ground discharge, and even directly causes casualties
