最近,日本北陆电力公司与住友电工公司共同研制出防雷光导纤维传输式静止型大坝水位计.目前已在富山县早月川水系上的白萩水电站(装机3,200千瓦)的进水口安装了这种自动水位计,开始了长期的实用验证工作.该水位计采用了光导纤维缆索传输,使发生雷电时,高压冲击电流不能侵入到传输线路中,可防止水位计测电路和遥测电路被烧坏.另
Recently, Hokuriku Electric Power Co., Ltd. and Sumitomo Electric Co., Ltd. jointly developed a mine-protected optical fiber transmission static dam water level gauge, which has been installed at the inlet of the Baie Hydropower Station (installed capacity of 3,200 kilowatts) on the Zuoyuechuan water system in Toyama Prefecture This kind of automatic water level gauge, started the long-term practical verification work.The water level meter uses the optical fiber cable transmission, causes when the thunder and lightning, the high-pressure impact electric current can not intrude into the transmission line, can prevent the water level measurement circuit and the telemetering circuit from being burned Bad
