摘要：随着电力工业的发展，对设备的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。本文介绍了安科瑞无线测温产品在北京大兴国际机场的应用。

Abstract: With the development of the electrical industry, the re for the safety and reliability of e are getting higher and higher. Under this condition, a wireless temperature measurement system for high-voltage e came into being. It is to install temperature sensors with batteries or CT powered at each temperature measurement point. The sensor sends the temperature measurement data to the receiving unit, and the receiver can be connected to the system to realize the electrical temperature monitoring. This article introduces the application of Acrel wireless temperature measurement products in Beijing Daxing International Airport.

1.Project Overview项目概述

北京大兴国际机场建设在北京市大兴区与河北省廊坊市广阳区之间，是超大型国际航空综合交通枢纽。该机场航站楼高压变电站分为三个部分：开闭站，指廊和核心区，其中，开闭站包括116面高压柜，指廊包括40面高压柜，核心区包括80面高压柜，以及其他配电部分包括430面高压柜。安科瑞为其提供了无线测温解决方案，每面高压柜断路器上下触头、电缆接头9点测温，共668面高压柜，无线测温传感器共计6015点。每面高压柜安装一台ASD320智能操控装置。

As a large international transportation hub, Beijing Daxing International Airport is located between Beijing Daxing District and Guangyang District, Langfang City, Hebei Province. The airport terminal high-voltage substation includes 668 high-voltage cabinets. Acrel provided it with a wireless temperature measurement solution. The upper and lower contacts and cable joints of each high-voltage cabinet were tested at 9 points. There were a total of 6015 wireless temperature sensors. At the same time, it should be installed an ASD320 intelligent control device on each high-voltage cabinet.
