两起电压致热型设备缺陷的诊断分析

Diagnosis Analysis of Defects in Two Voltage Induced Thermal Equipment

介绍了两起电压致热型设备缺陷诊断分析过程。通过红外测温发现设备的发热故障后,结合停电试验和解体检查等方法,确定了缺陷位置和缺陷原因。最后从环境温度参照体、环境温度、测试距离等方面给出了红外测温的注意事项。

The diagnosis analysis process of defects in two voltage induced thermal equipment is introduced.After the overheat fault of equipmentis found by infrared temperature measurement,the defect location and reason are determined combing with methods of power of test and disassembly inspection and so on.Finally,attentions to the use of infrared temperature measurement are proposed from aspects of environment temperature reference body,environment temperature,measurement distance and so on.
