上海测震、地球物理台站运行中，因电源系统和雷电而导致的故障占了较大比例。为提升台站运行质量而研发的隔离电源系统，可有效地将市电与台站设备间进行物理隔离，杜绝了雷击通过交流电供电途径的串入。该系统研制成功后，在上海测震台站试运行，其间发现了系统的一些缺陷，技术人员进行多次改进，提升了系统的整体性能。该系统已在多个测震、地球物理台站应用，取得了显著的防雷、防浪涌效果。
In the operation of the Shanghai seismic stations and geophysical stations, the fault caused by power supply system and thunder and lightning accounts for a large proportion. In order to improve the operation quality of the station, the isolation power supply system developed by technicians effectively isolates the municipal power and station equipment physically and prevents lightning strikes from entering the AC power supply channel. After the successful development of the system, some defects of the system have been found in the trial operation of the Shanghai seismic stations. Technical personnel have made many improvements to improve the overall performance of the system. The system has been applied in many seismic stations and Geophysical stations, and achieved remarkable lightning protection and surge protection effects.
