| With the development of power industry, the state has increased the intensity of electrical equipment automation, the use of modern technology is basically realized the power of unattended equipment, electrical equipment and management to further develop. Currently, the main use of infrared thermal tester timing for substation equipment inspection, this detection method can not obtain timely information substation equipment failure, delays in substation equipment maintenance time, unable to grasp the law of substation equipment failure, can not be achieved full dynamic monitoring of substation equipment. Therefore, an urgent need for the proposed new substation equipment failure detection system. Based on this, to substation equipment online temperature fault diagnosis system design and application for the study, to achieve the full dynamic monitoring of substation equipment. The main research contents are as follows:First, based on domestic and foreign research status review, infrared monitoring of substation equipment outlined the basic theory, basic introduction infrared detection equipment, analytical factors Infrared technology to detect errors made infrared camera selection strategy, which is the theoretical basis of this study.Second, an overview of substation equipment failure and infrared diagnostic methods, mainly outside the internal analysis of substation equipment failure, combined substation equipment failure analysis, infrared diagnostic methods are summarized and made for factors affecting infrared camera to detect errors factors in the infrared monitoring accuracy. Finally, substation equipment online temperature fault diagnosis system design, mainly from the hardware and software aspects of substation equipment online temperature fault diagnosis system design.This design of substation equipment online temperature fault diagnosis system is able to automatically collect data substation equipment, and automatic processing of infrared images displayed substation equipment temperature monitoring point and the temperature set by the judge whether there substation equipment faults and defects. At the same time, enables automatic regular daily inspection of the thermal fault monitoring and diagnosis, monitoring and control equipment, but also can realize remote monitoring of substation equipment, remote maintenance personnel to provide the basis for real-time analysis of equipment defects, has a very broad application prospects. |
