摘要

针对红外测温只能发现设备异常

无法准确诊断设备故障的问题。设计了一套基于案例推理技术的电力设备红外诊断方法。将电力企业现有的红外图谱和设备故障内外部温度变化规律建成案例库

依据空间向量的夹角余弦法求解同红外测温异常数据最相似的以往案例

实现测温现场的设备故障诊断。

Abstract

Considering the infrared temperature measurement can only be found in abnormal equipment

cannot accurate diagnosis of equipment fault problem. A method of infrared diagnosis for power equipment based on case based reasoning is presented. Case base

which based on power enterprise existing infrared spectrum and equipment fault external temperature variation rule

is established. According to the space vector angle cosine method

the most similar to the infrared temperature measurement anomaly data in the previous cases is obtained

finally

the equipment fault diagnosis of temperature field is realized.
