城市轨道交通新型埋入式杂散电流测防端子

A New Type of Embedded Stray Current Testing Terminals for Urban Rail Transit

在地铁杂散电流防护系统的施工过程中,扁铜测防端子施工难度大且极易失窃,难以保证杂散电流防护系统的完整性。结合现场实际情况,提出一种防盗效果明显、施工简单,并且更可靠、更经济、更美观的连接方式及替代产品。这种新型的埋入式杂散电流测防端子,在西安地铁1号线轨道道床施工中被采用,取得了很好的效果。

In the construction process of the protection system against metro stray current,the integrality of protection system with the flat copper testing terminal is hard to be guaranteed,because the flat copper testing terminal is difficult to be constructed,and because it is easy to be stolen.Based on the actual situation,a new connection model and alternative products are presented in this paper.The new one has obvious anti-theft effect.In addition,the new one is convenient to construction,more reliable,more economic and more beautiful.It has been adopted in track bed construction of Xi'an Metro Line 1 and the very good results have been achieved.
