Abstract: With the development power industry,the requirements for the safety and reliability of equipment are getting higher and higher. In this situation,ACREL wireless temperature monitoring system is designed for high voltage device. This technology is to install the temperature sensor with built-in battery or temperature sensor by current sensing and wireless transmitter module at each temperature measurement point. The sensor periodically sends the temperature measurement data wireless to the receiving unit, and the receiving unit can be connected to the network to send the data to the master station, thereby realizing electrical temperature monitoring of a regional system.
This article introduce wireless monitoring system used in substations in Netherlands.
1.当前现状 Current Status
多年来，由于技术水平的限制，虽然曾利用红外测温仪、红外成像仪、感温电缆、传统的点式测温系统希望解决上述问题，但都无法实现开关柜内如断路器、刀闸联接点和触头测温。目前，国内电力测温主要应用红外点测仪和光纤测温仪，而在线方式由于无法解决高压绝缘问题，所以高压开关的触点等空间有限的电气设备基本上都是处于完全无监控的状态下运行，存在重大安全隐患。
For many years, due to the limitations of the technical level, although infrared thermometer, infrared imager, temperature sensing cable, traditional point-type temperature measurement system have been used to solve the above problems, but can not achieve the switch cabinet such as circuit breaker, the connection point and contact temperature measurement. At present, domestic electric temperature measurement mainly uses infrared point measuring instrument and optical fiber temperature measuring instrument. However, the on-line method cannot solve the problem of high-voltage insulation, so the electrical equipment with limited space, such as the contact of high-voltage switch, basically operates in a completely unmonitored state, with major safety hazards.
