无源无线式在线测温技术的应用
Application of Passive Wireless Online Temperature Measurement Technology
摘要
Abstract
In allusion to problems of heat faults of contact sites of breakers,disconnector contacts and other joint parts of conducting bars of 1 0 kV switch cabinet in substation caused by surface oxide corrosion and fastening bolts looseness that may result in contact resistance increase,a kind of passive wireless online temperature measurement system applicable to tempera-ture measurement on key points of 1 0 kV switch cabinet based on surface acoustic wave technology was proposed and devel-oped. By means of existing substation comprehensive data network,this system could realize unified acquisition and trans-mission of temperature measurement information and it was provided with functions such as remote intelligent analysis and diagnosis,real-time and historical data statistic,Web browse and publishing and message alarm. This system had been suc-cessfully applied in 1 1 0 kV Taifen substation,Wenan substation and Yufeng substation of Zhongshan power supply bureau which had effectively monitored real-time heating of 1 0 kV switch cabinet equipments,realized centralized management on temperature measurement data of each substation and provided reliable support for state overhaul and timely defects elimina-tion of 1 0 kV switch cabinet equipments.关键词
