列车蓄电池电压的测量,是检查电池技术状态、发现电池故障、保证列车正常供电必不可少的手段,是蓄电池库内检查的一个重要项目。近年来,硅胶电池的推广,使电压的测量更显重要。过去,一般采用3伏电压表逐个测量电池电压的方法。此法由于作业过程繁琐(测量前需上车开灯,L型复式电池还需打开配 Train battery voltage measurement is to check the battery technology status and found that the battery failure to ensure the normal train power supply means essential is the battery storage check an important project. In recent years, the promotion of silicone batteries, the voltage measurement is even more important. In the past, the general use of voltmeter 3 volts one by one measure the battery voltage. This method due to the tedious operation process (before the lights on the car to be measured, L-type multi-battery also need to open with
