Title
(EN) OVERHEAD POWER DISTRIBUTION LINE
(FR) LIGNE AÉRIENNE DE DISTRIBUTION D'ÉLECTRICITÉ
(ZH) 架空配电线路
Abstract
(EN)
An overhead power distribution line (10) comprises a tension resistant pole (101), two composite crossbeams (102) and tension resistant fixing members (103). A middle portion of the composite crossbeam (102) is horizontally secured on the tension resistant pole (101), and end portions of the composite crossbeam (102) are connected to the tension resistant fixing members (103). The tension resistant fixing members (103) enable the two composite crossbeams (102) to integrally connect and are for fixing conducting lines. With the above configuration, two composite crossbeams (102) are secured on the same horizontal plane of the tension resistant pole (101), thus satisfying vertical tension of a tension resistant requirement. Further, by using composited crossbeam bodies (102), a dry arc distance is significantly increased, and electrical lightning resistance performance is enhanced, preventing incidents such as line disconnection and flashover caused by lightning strike. The composite crossbeams (102) are maintenance-free and do not require periodical inspection and maintenance, significantly reducing labor costs. The use of crossbeams (102) can further eliminate the use of tension insulators and simplify the structure of lines.

L'invention porte sur une ligne aérienne de distribution d'électricité (10) qui comprend un poteau résistant à la tension (101), deux traverses composites (102) et des éléments de fixation résistant à la tension (103). Une partie centrale de la traverse composite (102) est fixée horizontalement sur le poteau résistant à la tension (101), et des parties d'extrémité de la traverse composite (102) sont reliées aux éléments de fixation résistant à la tension (103). Les éléments de fixation résistant à la tension (103) permettent de relier d'un seul tenant les deux traverses composites (102) et sont destinés à fixer des lignes conductrices. Avec la configuration ci-dessus, deux traverses composites (102) sont fixées sur le même plan horizontal du poteau résistant à la tension (101), satisfaisant ainsi à une exigence de résistance à la tension verticale. En outre, par utilisation de corps de traverse composites (102), la distance d'arc sec est considérablement augmentée, et les performances de résistance à la foudre sont améliorées, empêchant des incidents tels qu'une déconnexion de ligne et un contournement provoqué par la foudre. Les traverses composites (102) sont sans maintenance et ne nécessitent pas d'inspection et de maintenance périodiques, réduisant considérablement les coûts de main-d’œuvre. L'utilisation de traverses (102) permet en outre d'éliminer l'utilisation d'isolateurs de tension et de simplifier la structure des lignes.

一种架空配电线路(10),包括:耐张杆(101)、两复合横担(102)和耐张固定件(103);复合横担(102)的中部水平固定于耐张杆(101)上,复合横担(102)的端部连接有耐张固定件(103),耐张固定件(103)使两复合横担(102)连接成一体,并且耐张固定件(103)用于固定导线。通过这种方式,在耐张杆(101)的同一水平面上固定有两个复合横担(102),能够满足耐张需要的纵向张力,进一步地,利用复合横担(102)本体的复合化,能够大大增加干弧距离,提高电气耐雷水平,避免雷击断线闪络等事故,复合横担(102)具有免维护性,无需定期检测和维护,大大降低人力成本,复合横担(102)的使用还可以省略耐张绝缘子,简化线路结构。
