Abnormal Temperature Rise Monitoring Method of Power Distribution Equipment Based on Infrared Thermal Imaging Technology

针对配电设备在运行过程中过热,引发设备故障或火灾等安全事故的问题,提出基于红外热成像技术的配电设备异常温升监测的方法。基于红外热成像技术采集配电设备的监测图像,对采集图像进行增强和去噪等预处理,从预处理后的红外图像中提取配电设备目标区域并计算温升值,利用相对温差法判断并定位设备过热现象,实现配电设备异常温升监测。实验表明,所设计方法监测的配电设备异常温升值和实际数据之间平均偏差为0.048℃,具有较高的异常温升监测精度。

Power distribution equipment in the operation process,due to various reasons may lead to equipment overheating,resulting in equipment failure or fire and other safety accidents.Therefore,a monitoring method of abnormal temperature rise of power distribution equipment based on infrared thermal imaging technology is proposed in this paper.The monitoring images of distribution equipment are collected based on infrared thermal imaging technology,and the acquired images are pre-processed such as enhancement and de-noising.The target area of distribution equipment is extracted from the pre-processed infrared images and the temperature rise value is calculated.The overheating phenomenon of equipment is judged and located by the relative temperature difference method to realize the abnormal temperature rise monitoring of power distribution equipment.The experimental results show that the average deviation between the distribution equipment abnormal temperature rise monitored by this method and the actual data is 0.048℃,which has a high abnormal temperature rise monitoring accuracy.
