Embodiment Construction

[0028] The specific implementation of the wall bushing in the present invention will now be described in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, it is an embodiment of the wall bushing in the present invention: the wall bushing includes a cylinder 10, and the cylinder 10 is along the figure 1 The left and right directions shown are extended. The cylinder body 10 is a split structure, including the transition cylinder body 13 passing through the wall 16, and also includes the right cylinder body 12 and the left cylinder body 12 respectively connected to the two ends of the transition cylinder body 13 through flanges. Cylinder 11. The wall bushing also includes a central conductor 20 arranged in the cylinder body 10, and the central conductor 20 is an integral structure. A cylinder end cover 15 is arranged at the opening of the left cylinder 11, and the cylinder end cover 15 is flanged to the opening of the left cylinder 11 by bolts so a...

Abstract

The invention relates to the technical field of through-wall conductive connecting devices, and provides a through-wall bushing. The through-wall bushing comprises a cylinder body and a central conductor, wherein one end of the central conductor is fixed together with a cylinder body end cover arranged at the corresponding end of the cylinder body, the other end of the cylinder body is fixedly connected with an elastic corrugated pipe, the elastic corrugated pipe is provided with a corrugated pipe end cover at the end away from the cylinder body, the other end of the central conductor is fixedwith the corrugated pipe end cover, and the elastic corrugated pipe provides tension for the central conductor to keep the central conductor tensioned. When the central conductor is heated to extend,the elastic corrugated pipe can drive the corrugated pipe end cover to straighten the extended central conductor, so that the sagging condition of the central conductor is improved, and the field intensity in the through-wall bushing is ensured to be uniform; moreover, two ends of the central conductor are fixedly connected with the corresponding end covers, thereby avoiding the generation of metal particles affecting the insulation due to the adoption of a sliding electric connection structure, guaranteeing the insulation safety, and enabling the through-wall bushing to be higher in reliability.

Description

technical field [0001] The invention relates to the technical field of wall-penetrating conductive connection devices, in particular to a wall-piercing bushing. Background technique [0002] The wall bushing can connect the conductors on both sides of the wall, and has been widely used in power engineering. The authorized announcement number is CN207977696U, and the patent document whose authorized announcement date is 2018.10.16 discloses a wall-piercing bushing. The wall-piercing bushing includes a first transport unit and a second transport unit located on both sides of the wall in the working state. , the first shipping unit includes the first bushing, the first bushing center conductor, and the first pot insulator contacts, while the second shipping unit includes the pot insulator, the second bushing, the second bushing center conductor, and the first pot insulator. Two pot insulator contacts. [0003] The first bushing is connected to the second bushing through the f...
