在电气化线路上,禁止到机冷车车辆外部登高作业。因此,在新造车结构上应有所改进,如在车辆两侧设置电气化线路禁止到车顶作业的标记;降低制冷机组工作踏板高度并设防护装置;改变制冷机组结构布局,使乘务员在较低的位置便能进行操作和维护保养工作。但是,最根本的途径还是要不断提高机电设备质量,向着自动化、无检修化的方向发展。
On the electrified lines, it is forbidden to climb to the outside of a chiller vehicle. Therefore, the new car structure should be improved, such as the provision of electrified lines on both sides of the vehicle forbidden to roof marking operations; reduce the working height of the chiller and the protective device; change the layout of the chiller, the flight attendant in the lower The location of the operation and maintenance work. However, the most fundamental way is to continue to improve the quality of mechanical and electrical equipment, toward automation, no maintenance of the direction of development.
