摘要
随着人民对于电力资源的依赖程度不断增加,电力设备安全已经成为当今社会研究的热点。在分析低压开关柜温度过高原因基础上,详细介绍了AD590温度传感器,结合S7-200 PLC设计低压开关柜温度在线监测系统和信号转换电路,实现对温度信号实时监测和故障分级报警。
With the increasing dependence of people on electric power resources,the safety of electric power equipment has become a hot research topic in today's society.Based on the analysis of the causes of the high temperature of the low-voltage switchgear,the AD590 temperature sensor is introduced in detail.Combined with s7-200 PLC,the on-line temperature monitoring system and the signal conversion circuit of the low-voltage switchgear are designed to realize real-time monitoring of the temperature signal and fault grading alarm.
