摘要
本文介绍了一种使用隔离装置隔离外部交流供电线路,通过蓄电池的切换实现直流隔离两种隔离措施的直流电源系统,旨在解决地震台站的电源避雷问题,保护台站设备免受雷击静电破坏。
In order to avoid the damaging caused by the lightning and provide the equipment with power, a protee-tive circuit to isolate the external AC power supply and DC power supply from the electronic equipment in seismic station is used. This circuit is designed with a switch in the device to reduce the operation time of external AC power supply in order to cut off the lightning inductance current.
