The Research And Application Of The Wireless Temperature Measurement Technology In10kV High-Voltage Switch Cabinet

With the development of the social economy and power technologies, thecustomers’ demand for continuous improvement of power supply reliability, designand construction of substations increasingly stylized, fully enclosed high voltageswitchgear systems are widely used in10kV220kV and110kV power substation. Itcan be said that10kV high voltage switchgear safe and stable operation can directlyaffect the reliable power supply to users. According to statistics, the operation ofsubstation equipment defects found, with the temperature accounted for more than80%. The scene of High Voltage Switchgear through constant development, structurehas changed dramatically due to cabinet space becomes smaller, the load currentincreases, the heat inside the cabinet of the equipment problem is getting worse. Thetraditional method of temperature measurement device structure is subject to, doesnot apply to already existing work requirements. In order to protect the safety of thepower grid and the equipment needed to find a suitable measuring means to achievethe full-sealed high voltage switchgear temperature monitoring in real time inside thedevices.This paper describes the integrated handling of Jiangmen Matanzas station10kV110kV high current knife fever defect leads online thermometry. By introducing theswitchboard online thermometry technology status, a comprehensive comparison ofthe current temperature mode Voltage Switchgear found at10kV High VoltageSwitchgear wireless temperature monitoring technology to the high-pressure linetemperature cabinet has technical advantages. So on the use of wireless temperaturemeasurement techniques have been studied from the principle, function, systemconfiguration, installation and other aspects of the site are described, followed byMatan station10kV high voltage switchgear110kV line temperature program asbackground, introduced the wireless temperature technology in practical applications,through the project proved the effectiveness and replicability wireless temperaturemeasurement system. To further enhance the wireless test technology research andapplications, this paper analyzes and compares the differences between centralizedand distributed wireless temperature measurement system active passive wirelesstemperature measurement system in practical engineering applications, verify thecentralized wireless active measurement temperature system has better prospects.Finally, the research and application of wireless temperature measurement techniques are summarized, wireless active temperature measurement system has studied theapplication of measurement data accuracy, high reliability, easy installation, lowconstruction volume characteristics, can better adapt to the needs of the site It can bewidely used in10kV high voltage switchgear, monitoring and early warning for onlinetemperature, power and equipment accident prevention.
