一种YRY钻孔应变仪的防雷隔离电源设计

Design of Lightning Protection Isolation Power Supply for YRY Borehole Strain Gauge

改制的自发电型隔离防雷电源具有供电完全物理隔离、防雷效果优秀、精度高、纹波小、不间断直流输出、供电故障手机拨号以及短信报警功能等特点,可有效阻止感应雷从交流电源和通信线路入侵,提高了监测仪器的防雷效果和运行率。

The restructured self-generating isolated lightning protection power supply has the characteristics of complete physical isolation of power supply,excellent lightning protection effect,high precision,small ripple,uninterrupted DC output,power supply fault cell phone dialing and short message alarm function,which can effectively prevent induction lightning from intruding from AC power supply and communication lines,and improve the lightning protection effect and operation rate of monitoring instruments.
