Furthermore, the sealing cover is integrally fixed on the wall body by the sealing cover fixing section through a half type pressing plate, the half type pressing plate is pressed on one side, far away from the wall body, of the fixing section and is fixed on the wall body through bolts, and the pressing force of the half type pressing plate on the fixing section towards the direction of the wall body is adjusted through adjusting bolts; as an optimal scheme, the pressure is applied to the circumferential direction of the half-type pressing plate, the whole stress of the sealing cover is relatively uniform, and the sealing cover can be more attached to a wall body to ensure the sealing performance.
Further, the outer section of the sealing cover is in a circular truncated cone shape; as an optimal scheme, the circular truncated cone shape is more beneficial to the rapid sliding of rainwater and other liquids, so that the performance change caused by water accumulation of an external section or other factors is avoided, and meanwhile, the circular truncated cone shape is beneficial to processing.
Further, the ratio of the thickness of the fixed section of the sealing cover to the height of the annular sealing boss is 1: 0.5-1; preferably, the proportion is determined by mainly considering the size of the general all-insulated tubular busbar sealing cover, and under the proportion, when the circumferential direction is uniformly stressed, one side, close to the wall body, of the annular sealing boss can be more attached to the surface of the wall body, and gaps generated by the insufficient performance of materials can be overcome.
Further, the sealing cover is a cold-shrink prefabricated integrated piece; as a preferred scheme, the cold-shrink prefabricated integrated piece is simpler and more convenient to process and has more excellent performance.
The utility model has the advantages that:
1. The utility model provides a full insulation tubular busbar sealing device is applicable to the full insulation tubular busbar and draws forth the open air from indoor, can be reliable plug up the rainwater, prevents that the rainwater from flowing indoor along the gap of tubular busbar or shrouding and wall body, and is sealed reliable, in the many sleets of specially adapted, moist and the corrosive environment.
2. The utility model provides a full insulation tubular busbar sealing device, the simple installation, easily construction, novel structure.

Detailed Description
The utility model discloses a core principle lies in: the wall through hole is sealed by adding the sealing device, so that the infiltration of external harmful substances such as rainwater and the like through the gap between the wall through hole and the fully-insulated tubular bus is avoided, and the operation safety of the power system is ensured.
In addition, wall body, including any check that all insulation tubular busbar need pass through keep off the thing, like building wall, prefabricated cabin casing etc..
The following detailed description is made in conjunction with the specific embodiments of the present invention:
as shown in fig. 1 and 2, the fully insulated tubular busbar sealing device comprises a sealing cover sleeved on a fully insulated tubular busbar and used for preventing water from penetrating through a wall hole; the sealing cover is of a three-section structure and comprises an external section, a fixed section and an internal section which are sequentially arranged along the direction from the outside of the wall to the inside of the wall; the outer section is arranged on the outer side of the wall body and used for guiding rainwater, the fixed section is arranged on the outer side of the wall body and used for integrally fixing the sealing cover on the wall body, and the inner section is arranged in the cavity and/or on the inner side of the wall body and used for isolating the inner wall of the wall penetrating hole from the all-insulation tubular bus.
The outer section of the sealing cover is in a round table shape, and the round table shape is more beneficial to rapid sliding of rainwater and other liquids, so that performance change caused by water accumulation of the outer section or other factors is avoided, and meanwhile, the round table shape is beneficial to processing. In actual processing, other different structural schemes can be selected, such as a cylindrical structure and the like, but the effect is poorer than that of a circular truncated cone.
At least two stages of annular sealing bosses are arranged on one side, close to the wall body, of the sealing cover fixing section, and the outer edge of the boss on the outermost side is collinear with the outer side of the fixing section. Considering the size of a general all-insulated tubular bus, two or three stages of annular sealing bosses are mostly selected, and when only one stage is set, the sealing performance is limited by material performance and is relatively general; if the number of stages is too large or the density is too large, the cost is high, the requirement of the sealing performance can be met by two stages to three stages, the improvement of the overall performance is not obvious by the arrangement of too many stages, and therefore two stages to three stages are recommended to be preferred. If the size of the fully insulated tubular busbar is increased, it is considered that the number of stages is increased appropriately to meet the requirement.
The ratio of the thickness of the fixed section of the sealing cover to the height of the annular sealing boss is 1: 0.5-1; in this example, the selection ratio is 1: 0.7, the size of full insulation tubular busbar sealed cowling is mainly considered in this proportion, and under this proportion, when the even atress of circumference, the wall body surface can be laminated more to annular seal boss one side near the wall body, and can overcome the not enough produced clearance of material self performance.
During the installation, the installation mode of multiple difference of optional, for example directly punch at the canned paragraph, through the fix with screw, nevertheless because the sealed cowling chooses the elasticity material more, the snap-on probably leads to the local atress great, and the fixed department is easy ageing deformation after long-time the use, and whole fixed inhomogeneous, in view of this, can provide a preferred scheme of preferred, adopt the haversian clamp plate to fix promptly. The half type pressing plate is pressed on one side of the fixed section, which is far away from the wall body, and is fixed on the wall body through a bolt, and the pressing force of the half type pressing plate on the fixed section towards the wall body is adjusted through an adjusting bolt; the haver type pressing plate is made of nonmagnetic material.
The sealing cover is made of elastic materials, preferably silicon rubber, ethylene propylene diene monomer and the like. The sealing cover is a cold-shrinkage prefabricated integrated piece; as a preferred scheme, the cold-shrink prefabricated integrated piece is simpler and more convenient to process and has more excellent performance.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope of the present invention, and these modifications or replacements should be covered within the protection scope of the present invention.
