1 前言随着列车的高速化,接触线的性能不断提高,张力自动补偿器也在提高性能方面进行了研究。针对以滑轮式(图1.a)为主的使用数年而无太大改动这一状况,新近研制开发了一种可取代滑轮式补偿器的高性能气体弹簧补偿器(图1.b、图2)。现已投入使用,包括私营铁路,目前已安装了250台。 1 Introduction With the high-speed train, the continuous improvement of the performance of the contact line, Tension Automatic Compensator has also been to improve the performance of the study. For a pulley-based (Figure 1.a) -based application that has been used for years without much modification, a high-performance gas spring compensator that can replace a pulley compensator has recently been developed (Figure 1.b, figure 2). Now put into use, including the private railway, has now installed 250 units.
