【摘要】：红外测温诊断技术具备非接触性的特点,能随时对运行中的设备健康状态进行诊断,在电力系统配电网内、外部故障诊断中迅速推广应用,有效的减少了停电检修次数并能够及时发现故障缺陷。因此,进一步加大红外测温诊断技术在配电网中的应用研究,逐步提高诊断技术的实用性和普遍性具有十分重要的意义。首先,对配电网故障诊断的发展背景进行了阐述,对国内、外红外测温诊断技术在电力系统中的应用情况和清远供电局故障诊断现状进行了调研。通过对比,发现清远供电局采用红外成像仪对电气设备进行故障诊断仍处于空白,为明确本文主要研究内容和主要研究方向提供了依据。其次,全面研究红外测温诊断技术,清晰红外线的基本特性、红外辐射的基本规律、红外热成像的基本原理以及故障热像图谱识别技巧等,清晰电气设备发热故障的成因和影响、电气设备内外部故障诊断的原理和方法等。最后,将成熟的理论引用到清远市配电网,摸索编制了管理标准和作业指导书,明确了工作要求、操作方法、检测周期和故障判断等依据,形成了一整套的作业表单,规范了在线监测各环节的工作流程;引用了近两年红外测温诊断的典型案例,通过案例分析证明了该技术在清远市配电网状态检修中应用的重要性和必要性。
[Abstract]:Infrared temperature measurement and diagnosis technology has the characteristics of non-contact, it can diagnose the health status of the equipment in operation at any time, and it can be applied rapidly in the distribution network of power system and external fault diagnosis. Effectively reduce the number of outages and repair, and can find fault defects in time. Therefore, further increase the infrared temperature diagnosis technology in distribution network application research. It is very important to improve the practicability and universality of diagnosis technology gradually. Firstly, the development background of distribution network fault diagnosis is expounded. The application of external infrared temperature measurement and diagnosis technology in power system and the fault diagnosis status of Qingyuan Power supply Bureau are investigated and compared. It is found that the fault diagnosis of electrical equipment by infrared imager in Qingyuan Power supply Bureau is still blank, which provides the basis for clarifying the main research content and main research direction of this paper. The technology of infrared temperature measurement and diagnosis, the basic characteristics of clear infrared ray, the basic rules of infrared radiation, the basic principle of infrared thermal imaging and the techniques of fault thermal image recognition are studied in an all-round way. It is clear the cause and influence of heating fault of electrical equipment, the principle and method of internal and external fault diagnosis of electrical equipment. Finally, the mature theory is applied to Qingyuan distribution network. The management standard and operation instruction are worked out, the working requirements, operation methods, inspection period and fault judgment are defined, a set of job forms are formed, and the work flow of on-line monitoring is standardized. The typical cases of infrared temperature measurement and diagnosis in recent two years are cited, and the importance and necessity of the application of this technology in the condition maintenance of distribution network in Qingyuan City are proved by case analysis.
