摘　　要：蓄电池过充电和过放电是导致其损坏的主要原因。质子磁力仪电源系统向用户提供了防止过充电和欠充电的铅蓄电池浮充电源、避免过放电的终止放电报警器和恒流输出式地磁分量补偿电源。介绍了该电源系统的性能和特点,各部分电路的工作原理、调试方法及使用注意事项。认为,使用该电源系统,不但可降低蓄电池的容量配制,延长其使用寿命,而且避免了充电和分量补偿电流调节的繁琐操作。The main reasofl led to a lead battery break is overcharge or overdischarge. A floating charging device for the power supply system of a proton magnetic instrument is worked out to prevent a lead battery from overcharging and undercharging, being of alarm device as discharge stopped, to avoid overdischarge, and constant current output geomagnetic component compensational source. In this paper, functions and features of the systems, principle of electronic circuits, debugging methods and cautions in the use are introduced. It is concluded that using this power supply system ,we can choose batteries with lower capacity, prolong battery＇s li^e-span and avoid the troublesome operation such as charge current adjusting and current compensating.
