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 wall-penetrating conductive connection devices, and provides a wall-penetrating bushing. The wall-piercing bushing includes a cylinder and a central conductor, and one end of the central conductor is fixed together with a cylinder end cover provided at the corresponding end of the cylinder. , the other end of the cylinder is fixedly connected with an elastic bellows, the end of the elastic bellows away from the cylinder is provided with a bellows end cover, the other end of the central conductor is fixed with the bellows end cover, and the elastic bellows provides the central conductor with tension force while maintaining tension in the center conductor. When the central conductor is heated and elongated, the elastic corrugated tube can drive the end cover of the corrugated tube to straighten the extended central conductor, improve the sagging of the central conductor, and ensure uniform field strength in the wall bushing; and both ends of the central conductor are aligned with the corresponding The end cover is fixedly connected to avoid metal particles that affect the insulation due to the structure of the sliding electrical connection, which ensures the safety of the insulation and makes the wall bushing have high 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...
