水情测站设备电源及防雷设计改进

Improvement for Power Source and Lightning Protection of Equipment in Hydrologic Forecast Stations

白溪水库原野外水情测站设备接线凌乱、频遭雷击,不仅增加了测站巡检工作的强度和频率,也严重影响到雨情、水情信息测量的准确性和可靠性。针对现状,对测站设备电源回路及防雷设计进行了改进,采用了三级防过电压设计,同时将设备整理入柜。实践证明,测站设备工作可靠性大幅度提高,保证了信息的及时采集与传输。

The equipment of the hydrologic forecast station of Baixi Reservoir is frequently struck by lightning for the disordered equipment connection. Not only the intensity and frequency of the tour inspection is increased, hut also the veracity and reliability of the hydrologic information is affected seriously. For this three-level overvoltage protection is adopted to improve the equipment power supply loop and lightning protection design, and the equipment is placed into a cabinet. It is proved that the reliability of the equipment is improved greatly, and at the same time, the information collection and transmission is guaranteed.
