Embodiment 1

[0028] Such as Figure 1 to Figure 3 Shown is the first embodiment of a wall-through porcelain bushing joint sheath of the present invention, including a sleeve body 1, one end of the sleeve body 1 is detachably connected to a sealing structure 2, and the sealing structure 2 is provided with a pipe-shaped The opening structure 21 through which the busbar passes.

[0029] The main body of the sleeve 1 is used to wrap the through-wall porcelain bushing joint, prevent the wall-through porcelain bushing joint from being exposed, and avoid the occurrence of thermal ablation accidents caused by corrosion of the connection position of the bus bridge; the sealing structure 2 can improve the protection of the through-wall porcelain bushing joint. The sealing performance of the sleeve; the setting of the opening structure 21 can facilitate the passage of the tubular busbar, so that the sheath of the through-wall porcelain bushing joint can be adapted to the joint.

[0030] In addition,...

Embodiment 2

[0043] This embodiment is similar to Embodiment 1, the difference is that in this embodiment, if Figure 1 to Figure 3 As shown, the sleeve main body 1 is a rubber sleeve. The sealing structure 2 is a rubber sealing structure. The arrangement of the rubber sleeve and the rubber sealing structure can improve the aging resistance and acid and alkali resistance of the sleeve main body 1 and the sealing structure 2, and increase the service life.

Abstract

The invention relates to the technical field of power system equipment protection, in particular to a through-wall porcelain bushing joint sheath which comprises a bushing main body, one end of the bushing main body is detachably connected with a sealing structure, and the sealing structure is provided with an opening structure convenient for a tubular bus to pass through. According to the invention, the through-wall porcelain bushing joint can be protected, exposed corrosion is prevented, thermal ablation accidents are reduced, and the safety of a power system is improved.

Description

technical field [0001] The invention relates to the technical field of power system equipment protection, and more particularly relates to a wall-through porcelain bushing joint sheath. Background technique [0002] At present, the insulation protection box of the through-wall porcelain bushing joint is made of cross-linked polyolefin material, which is closed and fixed by an open-type pin or a cable. However, the sealing performance of this kind of protective box is poor, and humid air and rainwater are easy to accumulate in the protective box, forming water accumulation at the bottom; moreover, the existing insulating protective box is easy to fall off due to aging and brittleness, so that the through-wall in the protective box The joints of the porcelain bushings are exposed. If the joints of the through-wall porcelain bushings are corroded by rainwater for a long time, it is easy to cause heat and ablation accidents and affect the normal operation of the power system. ...
