EPS应急电源在高速公路长隧道中的应用研究

高速公路长隧道机电系统一旦瘫痪无法工作，便存在严重的交通安全隐患，EPS应急电源的性能特点使其可以很好地预防这类因电力而导致的一系列事故。基于对EPS工作原理的简要介绍，并将其与柴油发电机组和UPS进行对比分析，结果表明．EPS以其特有的优势具有广阔的应用空间。

Application of Emergency Power Supply in Highway Long Tunnel

When electrical power system is paralyzed in highway long tunnel, there is serious hidden traffic danger. In this context, EPS(Emergency Power Supply) can prevent a series of accidents, playing an important role because of its property. The EPS principle of work is introduced simply and made contrast with the electrical generator and UPS. The results show that EPS has widespread application scope for its advantages.
