摘　　要：随着电力工程的大规模建设,社会对环保的重视,对基本农田的保护,超(特)高压工程换流(变电)站选址变得越来越困难,站址外留给输电线路终端塔的空间也越来越狭窄,导致换流(变电)站外,经常产生档距极小的进线档,给换流(变电)站的进线档的设计和施工带来很大困难。针对渝鄂直流背靠背联网工程北通道换流站外出现的一处特小进线档采取差异化设计,解决该进线档的档距过小,进线结构无法按常规的“耐张串—导线—耐张串”的型式进行设计的问题,通过使用新型的V型进线结构,解决档距特小情况下导线的进站问题,从技术和经济性上为换流(变电)站进线档的设计提供了新的思路。With the large-scale construction of electric power engineering,the society attaches importance to environmental protection and the protection of basic farmland.It becomes more and more difficult to locate the converter (substation) station of ultra-high voltage project,and the space left for the terminal tower of transmission line outside the station site is also more and more narrow,which leads to the formation of very small span outside the converter (substation) station.In this paper,the differential design is adopted for an extra small incoming line outside the converter station of Chongqing Hubei back-to-back VSC-HVDC Project,which solves the problem that the incoming line structure cannot be designed according to the conventional "tension string-conductor-tension string" type.By using a new V-type incoming line structure,this paper provides a new idea for the design of incoming line in converter (substation) station in terms of technology and economy,and achieves good economic and social benefits.
