Abstract: With the development of the electrical industry, the requirements for the safety and reliability of equipment are getting higher and higher. Under this condition, a wireless temperature measurement system for high-voltage equipment 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項目概述

　　北京大興國際機場建設在北京市大興區(qū)與河北省廊坊市廣陽區(qū)之間，是超大型國際航空綜合交通樞紐。該機場航站樓高壓變電站分為三個部分：開閉站，指廊和核心區(qū)，其中，開閉站包括116面高壓柜，指廊包括40面高壓柜，核心區(qū)包括80面高壓柜，以及其他配電部分包括430面高壓柜。安科瑞為其提供了無線測溫解決方案，每面高壓柜斷路器上下觸頭、電纜接頭9點測溫，共668面高壓柜，無線測溫傳感器共計6015點。每面高壓柜安裝一臺ASD320智能操控裝置。

　　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.

2.Introduction of Wireless Temperature Measurement Products無線測溫產品介紹

　　電氣接點無線測溫產品適用于中低壓開關柜內電纜接頭、斷路器觸頭、銅排，室內橋架、電纜，以及設備表面等場所的溫度監(jiān)測，及時、持續(xù)、準確反映設備運行狀態(tài)，提高設備保障。

　　Wireless temperature measurement products are suitable for temperature monitoring of cable joints, circuit breaker contacts, copper bars, cables, and equipment surfaces in medium-voltage and low-voltage?switchgear, and reflect the operating status of equipment in a timely, continuous and accurate manner to improve the safety on equipment.
