摘　　要：为实现电力设备的安全可靠运行,针对电力设备汇控柜内元器件及二次回路发热问题,结合红外热成像检测技术的应用实践,文中研究了电气设备汇控柜中二次端子排和接触器接线端的异常发热。依据相关的检测数据,采用表面温度判断、相对温差法和同类比较判断方法分析了上述发热问题的成因,并提了具体的处理方案。通过对汇控柜的红外热成像检测,为汇控柜的状态检修提供可靠的数据,同时也为红外测温技术在继电保护及安全自动装置等二次设备上的应用提供依据。In order to achieve the safety and reliability operation of electrical equipment, the thermal problem of secondary terminal and contactor connector in control cubicle are researched by combined with the application practice of the infrared thermal imaging detection technology. The reasons of abnormal thermal are analyzed through employing the surface temperature of comparison, relative temperature different methods and same kind comparison methods according to the related testing data, and give out the specific processing scheme. It provides a reference for the condition-based maintenance of control cubicle and the application of secondary equipment.
