Analysis of Forms for Design of Phase Break of Overhead Contact System

接触网电分相形式主要有器件式和关节式2种形式,而关节式电分相又派生出6跨、7跨以及三断口等类型。此文主要阐述接触网电分相形式选择的依据因素、分析比较各种电分相形式的技术特点并给出结论,望为接触网电分相设计提供参考。

There are two forms of phase breaks for overhead contact system mainly including component type and overlap type, and the overlap type phase breaks may be subdivided into phase breaks with 6 spans, 7 spans and overlap phase break with 3 breaks. The paper mainly illustrates the factors for selection of types of phase breaks of overhead contact system, analyzes the characteristics of various phase breaks to get the conclusions in order to provide reference for design of phase breaks for overhead contact system.
