Embodiment Construction

[0025] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] Specific embodiment one of the novel wall bushing assembly of the present invention, as Figure 2 to Figure 3 As shown, the wall bushing assembly includes an intermediate cylinder 1 and insulating sleeves 2 located at both ends of the intermediate cylinder 1 in the axial direction. The intermediate cylinder 1 and the insulating sleeve 2 together form a sleeve, and there is an insulating medium inside the sleeve. The housing chamber is provided with a hollow conductive rod 3 in the housing chamber, and a connecting flange 4 is sealed and fixed at the openings at both ends of the casing. The connecting flange 4 is provided with a conductive rod perforation, and one end of the conductive rod 3 is The conductive rod on the connecting flange 4 is pierced through the hole, and the pierced part forms the piercing section of the conductive rod.

Abstract

The invention relates to a novel wall bushing assembly, so as to solve the problem of easy damage caused by over large pretension of an elastic supporting piece on a conductive rod in the prior art. The wall bushing assembly comprises a stop structure fixedly connected with the penetrating out section of the conductive rod, the elastic supporting piece arranged between the stop structure and a fixing structure in an elastic supporting mode, and an adjusting piece adjustably arranged on either of the stop structure and the fixing structure. The adjusting piece adjusts the pretension on the stopstructure through the following one mode: 1) a spring is arranged between the other one in the stop structure and the fixing structure and the adjusting piece in an elastic supporting mode, and the spring acting force on the stop structure and the elastic supporting piece acting force on the stop structure have opposite directions; and 2) a transition plate which is fixedly connected with the adjusting piece is arranged between the stop structure and the fixing structure, and the adjusting piece is adjustably arranged on one of the two, and the elastic supporting piece is arranged in an elastic supporting mode between the other one and the transition plate.

Description

technical field [0001] The invention relates to a novel wall-piercing bushing assembly. Background technique [0002] UHVDC transmission is the best technical solution for large-scale long-distance transmission of new energy and other electric power, and it is an important force to promote the development of low-carbon strategic emerging industries. In the next few years, the market demand for UHV DC wall bushings will increase greatly. Before 2020, my country is expected to build 23 UHV DC projects, and the market prospect is very broad. UHV DC SF 6 The gas wall bushing has the advantages of relatively simple structure and relatively light weight, and will be the mainstream direction of UHV DC wall bushing development in the future. UHV SF 6 The length of the central conductive rod for gas wall bushings is generally about 25 meters. If there is no support in the middle, the deformation is serious. Under UHV, the field strength distribution is difficult to achieve an ide...
