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

Embodiment Construction
[0025] The best embodiment of the present invention is described in detail below in conjunction with accompanying drawing:
[0026] Embodiment: be used for shielding the cement pole shaft and the mother-in-law insulating shield of double cross-arm simultaneously (referring to Figure 1-Figure 6 ), including the insulating shielding mother cover 1 and the insulating shielding sub-cover 2, both of which are made of insulating rubber with a thickness of 0.004 meters, which can not only ensure the insulating shielding performance, but also have a certain mechanical strength, which is convenient for installation and use.
[0027] The insulating and shielding mother cover 1 is composed of the shielding part of the electric pole shaft of the mother cover and the shielding part of the cross arm of the mother cover.
[0028] The pole shaft shielding part of the mother cover is composed of the upper shaft shielding part 11 of the mother cover and the lower shaft shielding part 12 of the...

The invention discloses a male and female insulation shielding cover used for simultaneously shielding a cement pole body and double cross arms. The male and female insulation shielding cover is characterized by comprising a female insulation shielding cover (1) and a male insulation shielding cover (2); a female cover electric pole body shielding part is composed of cylindrical female cover upper and lower pole body shielding parts with openings and the 270-degree arc cross sections; a female cover cross arm shielding part is formed by connecting a female cover front cross arm and pole body connecting position shielding part and female cover left and right cross arm shielding parts; a male cover electric pole body shielding part is composed of cylindrical male cover upper and lower pole body shielding parts with openings and the 270-degree arc cross sections; a male cover cross arm shielding part is formed by connecting a male cover front cross arm and pole body connecting position shielding part and male cover left and right cross arm shielding parts. The male and female insulation shielding cover is simple in structure, safe, reliable, flexible in adjustment, stable in installation and wide in application range, hot-line work efficiency is improved, hot-line work safety is guaranteed, the insulation shielding efficiency is effectively improved, and the labor intensity of workers is reduced.
Description
Technical field: [0001] The invention relates to a combined insulation shielding cover for simultaneously covering the shaft of a cement pole and double cross-arms, which is widely used in live replacement of straight pole insulators, strain insulators, electrified vertical removal towers, and electrified straight pole replacement for overhead power distribution lines. The utility model relates to the insulation and shielding work of cement rod shafts such as tension rods and double cross-arms, and belongs to the field technical field of live maintenance. Background technique: [0002] Live work on power distribution overhead lines can not only avoid power outages for users, but also has more flexible working hours. With the continuous improvement of social and economic requirements for power supply reliability, the projects and scope of live work on power distribution lines have been expanding year by year. Due to the long-term operation of overhead distribution lines, equi...
