Abstract
As a key component of power system, the insulation status of high voltage electrical equipment directly affects the safe and stable operation of power grid. Therefore, the insulation monitoring and fault diagnosis of high voltage electrical equipment is of great significance. This paper focuses on the insulation monitoring and fault diagnosis technology of high voltage electrical equipment, aiming to improve the detection accuracy of equipment insulation performance and the accuracy of fault diagnosis by modern scientific and technological means, and provide a strong guarantee for the safe operation of power system. This paper introduces the basic principle and common methods of insulation monitoring of high voltage electrical equipment. Insulation monitoring measures the insulation resistance, dielectric loss Angle tangent, and partial discharge of the device to evaluate the insulation status of the device. Common monitoring methods include insulation resistance test, dielectric loss Angle tangent test, partial discharge test and so on. These methods have their own characteristics and can fully reflect all aspects of equipment insulation performance. This paper analyzes the technical means of fault diagnosis of high voltage electrical equipment in detail. In view of various faults that may occur in high voltage electrical equipment, such as mechanical faults, electrical faults, insulation aging, etc., this paper discusses a variety of fault diagnosis methods based on electrical parameter diagnosis, signal analysis diagnosis, spectrum analysis diagnosis. These methods can identify and locate equipment faults accurately by collecting equipment operating state information and using modern signal processing and data analysis technology. In the application of insulation monitoring and fault diagnosis technology, this paper emphasizes the importance of on-line monitoring and intelligent diagnosis. By installing sensors and monitoring equipment, real-time monitoring and data analysis of the operating status of high-voltage electrical equipment can be realized, and potential faults can be found in time and corresponding measures can be taken. At the same time, combining artificial intelligence and big data technology to build an intelligent diagnosis system can further improve the accuracy and efficiency of fault diagnosis. This paper summarizes the development trend of insulation monitoring and fault diagnosis technology of high voltage electrical equipment. With the continuous progress of science and technology and the intelligent development of power system, the insulation monitoring and fault diagnosis technology of high voltage electrical equipment will develop in the direction of more intelligent, networked and automated. In the future, through continuous technological innovation and optimization and upgrading, it will provide more solid technical support for the safe and stable operation of the power system.
