大电流封闭母线露点检测装置研究

Research on the large current enclosed bus dew point detection device maintenance

防止大电流封闭母线结露的设备一般需要检测母线内部的露点数据以确定设备启动或停止运行。空气露点仪依赖进口,价格昂贵。利用空气露点温度与空气温度、相对湿度之间的数学关系,依靠单片机计算及相关处理技术,可以把大电流封闭母线内部空气温度、相对湿度信号转换成露点数据,降低设备成本。

Preventing large current enclosed bus condensation equipment generally needs to detect bus internal dew point data to determine the start or stop of equipment.Grain generally depend on imports.The price is very expen-sive.Using the mathematical relationship between air dewpoint, air temperature and relative humidity.Relying on single chip microcomputer calculations and related processing technologies, the large current enclosed bus internal air relative humidity signal can be transformed into dew point data.This greatly reduces the equipment cost.
