The wall-penetrating ceramic sleeve is also called a wall-penetrating pipe, a waterproof sleeve and a wall embedded pipe, and can be divided into indoor and outdoor wall-penetrating ceramic sleeves according to the use environment; the main application scene is in the wall body of a transformer substation in a power plant, and the main application scene is that the electric energy generated by a generator is fed into a high-voltage power grid after being boosted through the wall body, so that the electric energy is a hardware pipe fitting which is suitable for a structure with vibration or strict waterproof requirement where a pipeline passes through the wall.
The prior art has at least the following problems: firstly, for outdoor through-wall porcelain bushing, because the high-voltage bushing is exposed outside throughout the year, various dust and dirt in the air fall on the high-voltage bushing, especially rain and snow, thunder and rain season easily cause insulation to descend, very easily cause the binding post of high-voltage bushing to discharge the wire inlet window through the bushing and form ground connection or alternate arc short circuit, and birds and reptiles cause the short circuit ground connection. Once the circuit fails, serious chain reactions such as large-area power failure and the like are caused.
Disclosure of Invention
According to the defects of the prior art, the cold-shrink protective sleeve device for the transformer substation through-wall high-voltage sleeve is developed, and is low in cost and simple and convenient to operate; and simultaneously, faults caused by dust accumulation, rain, snow, dampness and the like are reduced.
The technical scheme for solving the technical problems is as follows: the utility model provides a high-voltage bushing shrinkage protective sleeve device convenient to transformer substation wears wall, includes the shrinkage sleeve pipe, and the shrinkage sleeve pipe sets up to dual diameter structure, and the shrinkage sleeve pipe includes the different first section of diameter and second section, and first section inside nestification is provided with first braced skeleton, and the inside nestification of second section is provided with the second braced skeleton.
As optimization, a first extraction thread end is reserved at the outer side end of the first supporting framework.
As optimization, a second extraction thread end is reserved at the outer side end of the second supporting framework.
As an optimization, after the first supporting framework is removed, a gap is reserved between the first section of the cold shrink sleeve and the insulated wire.
As an optimization, after the second supporting framework is removed, a gap is reserved between the second section of the cold shrink sleeve and the high-voltage sleeve, and a gap is reserved between the high-voltage sleeve and the insulated wire.
As optimization, the surface of the high-voltage sleeve is smeared with silicone oil.
Compared with the prior art, the utility model has the following beneficial effects:
the inner wall of the external cold shrink sleeve can be supported through the first supporting framework and the second supporting framework which are horizontally arranged, and the double-diameter structure can be nested on different-diameter structures and is simultaneously used for free disassembly after being installed in place; the defects of the prior art are overcome, and the cold-shrink protective sleeve for the through-wall high-voltage sleeve of the transformer substation is provided, so that the cost is low, and the operation is simple and convenient; and meanwhile, faults caused by dust accumulation, rain, snow, dampness and the like are reduced.

Detailed Description
In order to clearly illustrate the technical features of the present solution, the present utility model will be described in detail below with reference to the following detailed description and the accompanying drawings.
Example 1
As shown in fig. 1, the transformer substation through-wall high-voltage bushing cold-shrink protective bushing device is convenient to support the inner wall of the external cold-shrink bushing 2 through a first supporting framework 3 and a second supporting framework 4 which are horizontally arranged, and the double-diameter structure can be nested on different-diameter structures and is simultaneously used for free disassembly after installation in place.
By arranging the first supporting framework 3 to be nested inside the cold shrink sleeve 2, the first extraction thread end 8 is reserved outside the first supporting framework 3 and can be used for free disassembly after installation in place.
By arranging the second supporting framework 4 to be nested inside the cold shrink sleeve 2, the second extraction thread end 5 is reserved outside the second supporting framework 4 and can be used for free disassembly after installation in place.
By providing a gap between the first section of the shrink sleeve 2 and the insulated conductor 7, a sufficient shrink space can be provided for the shrink sleeve 2.
By providing a gap between the second section of the shrink sleeve 2 and the high voltage sleeve 8, a sufficient shrink space can be provided for the shrink sleeve 2.
Through setting up silicone oil 6 at insulating wire 7 and high voltage bushing 8 surface, can fill shrink sleeve 2 first section and insulating wire 7 and shrink sleeve 2 second section and high voltage bushing 8's shrink space, improved shrink sleeve 2 insulativity.
The description of the orientation or relative positional relationship of the structures in the present utility model, such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., is based on the orientation or positional relationship shown in the drawings, is merely for convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the structures referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.
