试析紫外放电检测在输变电设备中的应用

Analysis of the Application of Ultraviolet Discharge Detection in Power Transmission and Transformation Equipment

紫外放电是电力设备运行过程中放电电晕的一种呈现形式,通常肉眼不可见,而带电运维过程中,通常采用紫外成像仪实现遥测。紫外成像仪携带不方便,对操作人员要求高且成本也相对高昂,因此不十分适用于当前的输变电设备检测工作。文章依据相关理论原理与实践经验分析一种具有智能预警以及移动功能的紫外放电监测与预警装置,旨在提升电力设备监测水平。

Ultraviolet discharge is a form of discharge corona during the operation of power equipment,which is usually invisible to the naked eye.In the process of live operation and maintenance,ultraviolet imagers are usually used to achieve remote measurement.The ultraviolet imager is inconvenient to carry,requires high requirements for operators,and is relatively expensive,so it is not very suitable for the current power transmission and transformation equipment inspection work.The article analyzes an ultraviolet discharge monitoring and early warning device with intelligent early warning and mobile functions based on relevant theoretical principles and practical experience,aiming to improve the monitoring level of power equipment.
