220kV同塔四回线路跨越高铁安全性分析
|
摘要
本线路为220 k V同塔四回路,与京沪高铁交叉跨越,采用耐—直—直—耐形式的独立耐张段进行跨越,在分析路径选择、气象条件、导地线使用、绝缘子和金具串使用、独立耐张段、净空距离、跨越塔与铁路距离、铁塔选材与设计、基础设计、铁塔使用条件、抗震设计等各方面因素后,均满足电力和铁路部门相关技术要求,确保本线路对高速铁路没有影响,确保高速铁路安全运行,实现电力与高铁双赢的目标。
The 220 k V transmission line with four circuits on the same tower crosses Jinghu high speed rail. The tension- suspension- tension type is adopted in crossing the tension independent span. Various influencing factors are anayzed,including route selection,meteorological conditions,conductor and earth line,insulators and fitting series,tension independent segment,clearance distance,distance between crossing tower and railway,tower material and design,foundation design,tower using conditions,seismic design,etc. It is indicated that the crossing meets the relevant technical requirements of the electricity and railway sectors,which ensures that the high speed railway can operate safely,achieving the mutually beneficial goal between power and high speed rail industry.
