摘要
项目推广中发现很多矿井主通风机的监测温度经常出现不同程度的虚高现象,分析其原因是测温线路的接线引起了较大的温度误差。文章对测温线路进行了理论分析,并通过实验得出导线电阻的大小对温度影响的关系。
In the application program, it was found that the monitored and measured temperatures of the mine main ventilators in many coal mines ware higher than the actual temperature. The research of the cause showed that the connection of the temperature measuring lines cased the temperature tolerance. After the theoretical analysis of the temperature measuring lines, the test results showed that the resistances of the conducted line have the relationship to the influence of the temperature.
