Abstract

In industrial systems, there are various situations, in which it’s difficult to monitor the temperature at a key point of an electrical equipment such as high power breaking breaks, automatic entrances, current paths, contact lines, force contacts from normal separations or load medium or high voltage circuits in electric power train systems or electric traction systems. In this paper we present a system for on-line monitoring of the temperature on the contact high voltage surface from a medium voltage monopolar separator used in the electric railway traction. An infrared temperature transducer is used which converts the temperature value into an electric signal in the 0-10v range. This electrical signal is used as an analogue input size for a Siemens S7-1200 PLC. An application was developed that monitors online temperature on the strength of the contact force, allowing the HMI monitor to view the temperature value, the actual size, and also the graphical evolution of the temperature values over a period of time. It also shows the experimental installation, the electrical drawing, the temperature value must fit within a certain acceptable range.

使用红外温度传感器连接PLC的温度监测系统

在工业系统中，存在各种难以监测电气设备关键点温度的情况，例如大功率断路器，自动入口，电流路径，接触线，从正常分离的力触点或电力列车系统或电力牵引系统中的负载中压或高压电路。本文介绍了一种用于电气化铁路牵引中压单极分离器接触高压表面温度在线监测的系统。使用红外温度传感器将温度值转换成0-10v范围内的电信号。该电信号用作西门子S7-1200 PLC的模拟输入尺寸。开发了一种应用程序，可以在线监测接触力强度的温度，允许HMI监视器查看温度值，实际尺寸以及温度值在一段时间内的图形演变。并说明了实验装置、电气图纸、温度值必须符合一定的可接受范围。
