Abstract

An ultra-high-voltage direct-current wall bushing and a support structure of a central conductor thereof. The central conductor of the wall bushing is divided into two parts, namely an indoor conductor (4) and an outdoor conductor (3). The indoor conductor and the outdoor conductor are fixed in a wall bushing body through the support structure arranged in the wall bushing body (1). The support structure is provided with a connecting contact head (2) which is used for fixedly connecting the indoor conductor and the outdoor conductor together. The connecting contact head is fixed on the inner wall of the wall bushing body through an insulator (5) which is fixedly connected with the connecting contact head. Because the length of the central conductor is formed by the lengths of the indoor conductor and the outdoor conductor, i.e., the longer length of the central conductor is formed by two general lengths or the shorter length, the problem of oversized deflection of the central conductor caused by overlong length of the central conductor is solved.

Description

特高压直流穿墙套管及其中心导体的支撑结构 技术领域  Support structure for UHV DC wall bushing and its central conductor
[0001] 本发明涉及直流输电设备技术领域中使用的一种特高压直流穿墙套管, 同时还涉及 该特高压穿墙套管的中心导体的支撑结构。  [0001] The present invention relates to an ultra-high voltage direct current wall bushing used in the technical field of a direct current power transmission device, and to a support structure of a center conductor of the ultra high voltage through wall bushing.

(阿尔斯通) 三家公司掌握, 国内厂家说大多还没有能够设计生产特高压直流穿墙套管的技术 能力。 目前市场上存在的一种特高压六氟化硫气体绝缘直流穿墙套管 (河南平髙集团自主研 发) 能满足我国特高压直流工程的技术要求。 该书特高压六氟化硫气体绝缘直流穿墙套管具有 电压等级髙、 爬电距离大, 中心导体长的特点。 但是由于中心导体的较长长度会使中心导体 的挠度增大, 从而致使穿墙套管内的电场强度集中, 进而使得该穿墙套管不能达到特高压六 氟化硫气体绝缘直流穿墙套管的预定设计要求。 (Alstom) The three companies are in control. Domestic manufacturers say that most of them have not yet been able to design and produce UHV DC wall bushings. At present, an UHV sulphur hexafluoride gas insulated DC through-wall bushing (Henan Pingyi Group's independent research and development) exists on the market to meet the technical requirements of China's UHV DC project. The book UHV hexafluoride gas insulated DC through-wall bushing has the characteristics of voltage grade 髙, large creepage distance and long center conductor. However, due to the longer length of the center conductor, the deflection of the center conductor is increased, thereby causing the electric field strength in the wall bushing to concentrate, and thus the wall bushing cannot reach the UHV hexafluoride gas insulated DC through wall bushing. Scheduled design requirements.
