Abstract

The invention discloses a segmenting method for a subway contact net lead in a CDEGS lightning model. The segmenting method is characterized in that a least value N of the number of contact net lead segments is calculated through a model, namely N=(m+1)*(2int[(25a-183) / 366]+3), wherein m is the number of span, a is the average span, and int[] is an integral function. The segmenting method aims at a subway system at a viaduct segment. An HIFRIQ module of CDEGS software is used for modeling the power supply mode of the subway contact net at the viaduct segment. The invention provides a conductor segmenting method for calculating an insulator withstand voltage of the subway line at the viaduct segment based on a CDEGS simulation model, wherein a requirement for high calculation precision is satisfied and calculating efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of simulation of subway catenary conductors, in particular to a segmentation method and system for subway catenary conductors in a CDEGS lightning impact model, which is used for the simulation method and system for lightning impact of subway catenary conductors. Background technique [0002] In recent years, with the continuous development of urban subway traffic, the subway has gradually become one of the main means of transportation for people to travel. The subway is favored by people for its quickness, punctuality, smoothness and other characteristics, and now many cities are building urban and intercity subways. Nowadays, the train running underground is no longer the main feature of today's subway. With the development of the line to the suburbs, the subway has changed from underground to ground or running on the viaduct. The current subway is an engineering construction project with a high concentra...
