  摘要:随着电力工业的发展,对设备的安全性、可靠性要求越来越高。在这种条件下,高压设备的无线测温系统应运而生。这种技术是将内置电池或电流感应和无线发射模块的测温传感器安装于各测温点,由于其体积小,且无需任何接线,其电气安全性可以得到保证。传感器周期性的将测温数据无线发送至接收单元,接收单元可联网将数据送至主站,以此实现一个区域系统的电气温度监测。

  本文介绍了无线测温传感器在荷兰某变配电室的应用

  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.

  2.项目概述 Project Overview

  荷兰DigIoT公司是一家电力物联网公司,为当地各变电站提供电力物联网服务。客户咨询安科瑞无线测温产品,希望通过安科瑞ATE无线温度传感器和ATC接收器,对开关柜内的线缆进行温度检测,并通过RS485通讯将数据传输到后台进行实时监控,从而可以有效预防开关柜内部过热发生故障,影响设备正常运转,避免安全隐患。

  DigIoT is an electric IoT company, providing electrical IoT services for local substations. Customer consults  Acrel wireless temperature measurement products, attending through Acrel ATE wireless temperature sensor and ATC receiver, the cable in the switchgear temperature detection, And through RS485 communication data transmission to the back platform for real-time monitoring, can effectively prevent overheating failure, affect the normal operation of equipment, avoid safety risks.
