摘要
针对蓄电池亏电对电力机车正常运用产生严重影响的问题,介绍一种蓄电池欠压保护装置,通过对既有电力机车进行电气改造,可实现对电力机车蓄电池输出欠压报警和切断保护。该保护装置充分考虑机车实际技术情况和运用习惯,具有高可用性、高安全性和高可靠性的特点及较强的应用价值。
Considering that lack of electricity of battery exerts a severe impact on electric locomotive,the paper introduces a battery low-voltage protection device.Through the electrified upgrade of the existing electric locomotive,the electric locomotive battery output low-voltage alarm and cut-off protection can be realized.The device takes practical and technical situation and operation conditions into account,boasting high availability,high safety,high reliability and relatively high application value.
