非电量在线检测技术在状态检修中的应用

由于非电量在线检测技术在生产实际中具有不停电、不取样、直观、准确、快速及安全等特点，通过对状态检修相关文件的分析，在设备状态检测过程中开展了红外／紫外检测技术、SF6气体激光检漏技术、局部放电超声检测技术等非电量在线检测技术的研究与应用，为输变电设备的状态检测提供了一种灵活的检测手段。

Application of Online Detection of Non-electrical Quantities to Condition-based Maintenance

Online detection of non - electrical quantities for electrical apparatus is a kind of detecting method without power cut - off and sampling, and possesses the advantages of accuracy, rapidity and safety during the site application. Based on the relevant files of condition - based maintenance （ CBM ） , the research and application of non - electrical quantities technique are summarized such as infrared/ultraviolet detection technique, SF6 gas leakage hunting technique using laser and ultrasonic detecting technique for partial discharge, which, undoubtedly, will be a contribution to the flexible detection for CBM of trans- mission and distribution equipment.
