超高温条件下利用电子自动读数设备进行压水试验

Pump-in tests by using electrical flow meters under extra-high temperature conditions

压水试验是大坝勘察的重要手段,其数据对大坝设计至关重要。为提高数据准确性,有的采用电磁流量仪,而电子设备在高温条件下运作情况不理想。本文根据夏季北部非洲某大坝勘察项目中压水试验中的经验和教训,总结出适合野外超高温条件下用电子设备进行压水作业的方法。

The pump-in test is a very important investigation method for hydropower project,and the results from the tests are the key factors for dam design.In order to get more exact readings,the electrical flow meters are used by some companies,but the electrical equipment could not perfectly perform under the extra-high temperature conditions.Based on the engineering experience in North Africa the suitable solution for the operation of electrical flow meters under the conditions is summarized.
