洪家渡水电站运行期内观仪器的鉴定

Identification of the instrument of Hongjiadu Hydropower Plant during operation

随着时间的推移,一些已建成的大中型水库大坝安全监测内观仪器逐渐出现损坏、失效、不稳定以及测值不能反映工程实际情况等问题,如何对内观仪器进行鉴定已成为当务之急。本文以洪家渡水电站运行期内观仪器的鉴定为例,根据弦式仪器、差阻式仪器、电阻式温度计、电位器式仪器的类别特点,探讨性介绍了仪器鉴定的现场测试方法、鉴定标准及仪器鉴定后的优化处理等,希望能起到抛砖引玉的功效。

The damage,failure,instability and inaccurate measure occur in the monitor instrument in the constructed large and middle sized with the time increasing. It was necessary to identify the inner instrument. The paper discussed the field test method,identification standard and the optimal treatment of the post-identification instrument,for the instrument according to the features of vibration wire instrument,the differential resistance instrument,potentiometer instrument,with the example of Hongjiadu Hydropower Plant instrument identification.
