Problems solved by technology

[0004] In order to overcome the problem in the prior art that the intersection of the line and the line is in an open and exposed state, it is very easy to form a ground fault and a short circuit accident, which seriously threatens the safe, stable and reliable operation of the overhead line, and provides a visual line. The head insulation cover adopts the combination of the double-layer structure inner clamping shell and the outer protective cover, which increases the insulation space, better the insulation effect, and the insulation cover is easy to assemble and install

Embodiment 1

[0027] Such as figure 1 and figure 2 As shown in the figure, a visual insulating cover for pile heads includes a transparent insulating cover 1, a mounting splint 2 and a mounting rod 3. The transparent insulating cover 1 includes an inner clamping shell 1.1 and an outer protective cover 1.2, and the inner clamping shell 1.1 is all Set in the outer protective cover 1.2. The section of the inner clamping shell 1.1 is an inverted U-shape, one side of the inner clamping shell 1.1 is fixed with the outer protective cover 1.2, and the other side of the inner clamping shell 1.1 is provided with a limiting plate facing the inner side of the U-shape 1.1.1, the free end of the limiting plate 1.1.1 is set obliquely upward. The mounting splint 2 is provided with an upward opening slot 2.1 and a vertical clamping hole 2.2. The upper end of the mounting rod 3 is provided with a clamping part 3.1, and the side wall of the clamping part 3.1 is provided with a limit rod 3.2. The lower end...

Embodiment 2

[0030] Such as figure 1 and figure 2As shown, on the basis of Embodiment 1, the installation rod 3 is provided with a lower stop rod 3.3, the lower stop rod 3.3 is perpendicular to the installation rod 3, the lower stop rod 3.3 is arranged below the clamping part 3.1, and the lower stop rod 3.3 Contact with the lower end of the clamping part 3.1. The lower stop bar 3.3 is threadedly connected with the installation bar 3 . The structure can prevent the installation splint 2 from sliding up and down relative to the installation rod 3 during installation.

Embodiment 3

[0032] A method for installing an insulating cover on a pile head with visualization, using the above-mentioned insulation cover on a pile head with visualization, including the following steps:

[0033] a. Insulation cover assembly: pass the clamping part 3.1 of the installation rod 3 through the clamping hole 2.2 of the installation splint 2, so that the clamping hole 2.2 utilizes its own elasticity and the tight fit between the clamping hole 2.2 and the clamping part 3.1 Clamp the clamping part 3.1, clamp the clamping part 3.1 with the clamping hole 2.2, make the limit rod 3.2 contact the upper end of the outer protective cover 1.2 at the same time, and then snap the lower end of the side plate of the outer protective cover 1.2 downward into the opening slot 2.1;

[0034] b. Insulation cover installation: move the transparent insulation cover 1 to the installation position through the installation rod 3, and snap the inner clamping shell 1.1 into the ring from top to bottom...

Abstract

The invention discloses a visual line connector upper pile head insulation cover and an installation method. The visual line connector upper pile head insulation cover comprises a transparent insulation cover, an installation clamping plate and an installation rod; the transparent insulation cover comprises an inner clamping shell and an outer protection cover; the installation clamping plate is provided with an open groove with an upward opening and a vertically arranged clamping hole; the upper end of the installation rod is provided with a clamping part; a limiting rod is arranged on the side wall of the clamping part; the lower end of the side plate of the outer protection cover is downwards clamped into the open groove; the clamping part penetrates through the clamping hole and is in tight fit with the clamping hole; and the limiting rod faces the outer protection cover, is arranged above the outer protection cover and makes contact with the upper end of the outer protection cover. According to the visual line connector upper pile head insulation cover and the installation method, the inner clamping shell of a double-layer structure and and the outer protection cover are combined, the insulation space is increased, the insulation effect is better, and the insulation cover is convenient to assemble and install.

Description

technical field [0001] The invention relates to the technical field of power equipment maintenance tools, in particular to an insulating cover and an installation method for a visual gram upper pile head. Background technique [0002] The electric high-voltage drop-type liner is widely used in branch lines because of its low cost, obvious action and obvious disconnection point. The connection with the line still needs to be connected with the terminal pile head clamp, and the upper seat of the fusion tube is also exposed. Therefore, the junction of the Kehe line is in an open and exposed state, which is very easy to cause ground faults and short-circuit accidents, which seriously threaten the safe, stable and reliable operation of the overhead line. However, the Lingke pile head insulation covers currently on the market are all wrapped with silicone rubber or hard plastic. These products have the following disadvantages: 1. Because the fixing method requires needle puncture...
