中文摘要:为保证换流变压器安全与稳定运行、及时发现套管内部由于放电引起的局部过热问题,研究了基于AR技术的换流变压器阀侧套管局部高温故障多点红外预警方法。考虑换流变压器阀侧套管的材料性能,以设备在实际工作状态下的正常温度变化为条件,根据套管的电流冲击变化形式,描述其温度场分布类型。基于AR技术构建三维虚拟空间,在摄像机三维跟踪过程中,转换现实场景中的被测物体信息,注册套管实时温度网。利用红外测距生成换流变压器阀侧套管温度直方图,以融合特征算法增强温度特征,对局部高温目标点定位,预警故障的具体位置。实验结果表明:本文方法能够在AR技术下对换流变压器阀侧套管进行场景转换,并在局部空间内标记出高温故障点位置,通过红外温度数据完成及时预警,具有应用效果。

Multi-point Infrared Early Warning Method for Local High Temperature Fault of Valve Side Bushing of Converter Transformer Based on AR Technology
Abstract:In order to ensure the safe and stable operation of the converter transformer and find out the local overheating caused by the discharge in the bushing in time, a multi-point infrared early warning method for the local high temperature fault of the bushing at the valve side of the converter transformer based on AR technology is studied. Considering the material properties of the bushing at the valve side of the converter transformer, taking the normal temperature change of the equipment under the actual working state as the condition, the temperature field distribution type of the bushing is described according to the current impact change form of the bushing. The virtual space is constructed based on AR technology. During the three-dimensional tracking process of the camera, the information of the measured object in the real scene is converted, and the casing real-time temperature network is registered. The temperature histogram of the bushing at the valve side of the converter transformer is generated by infrared ranging, and the temperature feature is enhanced by the fusion feature algorithm to locate the local high-temperature target point and warn the specific location of the fault. The experimental results show that the method in this paper can perform scene conversion on the valve side bushing of converter transformer under AR technology, mark the location of high-temperature fault point in local space, and complete timely warning through infrared temperature data, with application effect.
