高压电气设备内部故障红外成象诊断技术

Analysis of the Internals Faults of High Voltage Electrical Equipments with Thermography

在进行电气设备故障诊断方面，红外成象技术具有远距离、非接触、大面积成象、快速直观等优点，成为电气设备故障有效的诊断方法。以电气设备故障存在的部位而言，红外成象方法对外部故障的诊断简单明了，但对设备内部故障的诊断较复杂，必须掌握内部故障属性与对应的外部热象特征的关系。本文即为针对上述情况，论述红外成象方法在诊断电气设备内部故障方面的一些技术问题。

Thermograpy is an efficient way to diagnose electrical equipments with meritss such as, far distance, without touch, wide area, fast and directly perceived. External faults are easy to analyze. On the other hand, internal faults are much complex unless the relation of internal faults and relevant thermal images was totally grasped. Some technical problems were analyzed.
