摘 要

红外测温仪诊断技术对电气设备的早期故障缺陷及绝缘性能做出可靠的预测，使传统电气设备的预防性试验维修(预防试验是50年代引进前苏联的标准)提高到预知状态检修，这也是现代电力企业发展的方向。特别是现在大机组、超高电压的发展，对电力系统的可靠运行，关系到电网的稳定，提出了越来越高的要求。随着现代科学技术不断发展成熟与日益完善，利用红外状态监测和诊断技术具有远距离、不接触、不取样、不解体，又具有准确、快速、直观等特点，实时地在线监测和诊断电气设备大多数故障(几乎可以覆盖所有电气设备各种故障的检测)。它备受国内外电力行业的重视(国外70年代后期普遍应用的一种先进状态检修体制)，并得到快速发展。红外检测技术的应用，对提高电气设备的可靠性与有效性，提高运行经济效益，降低维修成本都有很重要的意义。是目前在预知检修领域中普遍推广的一种很好手段，又能使维修水平和设备的健康水平上一个台阶。
采用红外成像检测技术可以对正在运行的设备进行非接触检测，拍摄其温度场的分布、测量任何部位的温度值，据此对各种外部及内部故障进行诊断，具有实时、遥测、直观和定量测温等优点，用来检测发电厂、变电所和输电线路的运转设备和带电设备非常方便、有效

 Abstract

Infrared measured the warm meter diagnosis technology makes there liable forecast to the electrical equipment early breakdown flaw and the insulating ability, causes the tradition electrical equipment the preventive test service (prevention experiment is the 50's introduces former Soviet Union the standard) to enhance to knew in advance the condition overhaul, Unceasingly develops along with the modern science and technology maturely with day by day consummates, each kind of breakdown examination). It prepares the domestic and foreign electric powers profession value (overseas in the late 70's universal application one kind of advanced condition overhaul system), and obtains the fast development. The infrared detection technology application, to enhances the electrical equipment the reliability and the validity, enhances the movement economic efficiency, reduces the service cost all to have the very vital significance. Is at present in knows in advance in the overhaul domain the universal promoted one very good method, also can cause the  service level and in the equipment health standard a stair.
Uses the infrared imagery examination technology to be allowed to the equipment which moves to carry on the non- contact examination，photographs its temperature field the distribution, surveys any spot the temperature value, according to the above carries on the diagnosis to each kind outside and internal breakdown, has real-time, the telemetering, direct-viewing and decides and so on the merit warm, uses for to examine the power plant, the transformer substation and the transmission line revolution equipment and the charged equipment extremely convenient, is effective
