摘　　要：目前各地震台站都在使用UPS不间断电源对重要的仪器设备进行供电以保证地震仪器观测记录资料的连续性和完整性。但当UPS电源损坏时,仪器也就随之停止工作,一旦值班人员不能及时发现和排除,将造成长时间断记,给台站的监测工作带来很大影响。本文通过对UPS电源原理的一些研究,用时间继电器研制了一套电源自动切换和断电报警装置,在UPS电源出现无电压输出故障时能瞬间自动快速切换到由市电(交流电220VAC)给地震仪器和设备供电并发出报警信息。在切换过程中不会使地震仪器瞬间断电造成断记,解决了因UPS电源出现无电压输出故障造成的断记问题和断电报警问题。At present all seismic stations use uninterruptible power supply(UPS) to supply power to important instruments and equipment to ensure the continuity of data. But when the UPS is damaged the observation instrument will also cease to work. At this time if the duty personnel can not find and exclude in time it will cause a long time to break down which will bring great influence to the monitoring work of the station. In this paper a set of power switching alarm device is developed which can automatically switch the power and send out the alarm information at the moment of UPS failure. In the process of switching the instrument will not break the power of the instrument and cause the fault to be broken and the problem of the fault caused by the UPS fault is solved.
