一、前言现代铁路正在向着高速度、高密度的方向发展,同时要求车辆上装设的机器设备性能可靠、效率高。车辆备用电源的检修,主要是检查蓄电池液面和补水。若无须补水,就可以节约劳力。本文叙述车辆蓄电池使用状态、种类及无须补水的方法。二、使用状态车辆装设的蓄电池的用途可大致归纳为如下几个方面: (1)列车启动时给负荷供电: 通常用于柴油机启动、受电弓升降、小型皮带启动等。 (2)列车运行中给负荷供电:
I. INTRODUCTION Modern railways are moving in the direction of high speed and high density. At the same time, the requirements for the reliability of equipment installed in vehicles and the high efficiency are required. Vehicle spare power maintenance, mainly to check the battery level and make up water. If you do not need water, you can save labor. This article describes the vehicle battery status, types and methods without replenishment. Second, the use of State vehicles installed batteries can be broadly summarized as the following aspects: (1) the train starts to load power supply: usually used for diesel engine start, pantograph lift, small belt start and so on. (2) power supply to the load during train operation:
