超声波和TEV技术在配电网开关柜检测中的应用研究

Study on Application of Ultrasonic Technology and TEV Technology to Detection of Distribution Network Switchgear Cabinet

目前电网普遍采用带电检测技术获取设备运行状态,超声波、TEV技术作为设备状态检测的主要手段,已广泛应用于配电网开关柜现场检测。介绍了应用超声波和TEV技术在现场检测中获得的典型案例,证明了单一的检测技术存在偏差,将超声波和TEV技术相结合可以有效反映配电网开关柜的运行状态,为现有针对性的开关柜状态检修提供了可靠的技术支撑。

At present,grid charged detection technology has been widely used to attain equipment running status. Therefore ultrasonic and TEV technology,as the main means of equipment state inspection,has been widely used in distribution network switchgear on-site detection. In this paper,typical cases gained in situ test by the application of ultrasonic and TEV technology,prove that the existence of a single detection technology combined with ultrasonic and TEV technology can effectively reflect the running state of distribution network switchgear,in order to achieve targeted switchgear state overhaul and provide a reliable technical support.
