Abstract
With the continuous improvement of the voltage level of the power system and the continuous expansion of the scale of the power grid, the high-voltage switchgear is a crucial control and protection element in the power system, and its operating state is directly related to the safe and stable operation of the power grid. In order to ensure the long-term and reliable operation of high voltage switchgear, on-line monitoring and fault diagnosis technology is particularly important. In this paper, on-line monitoring technology system and fault diagnosis method of high voltage switchgear are deeply discussed, aiming at providing strong support for improving the automation level and maintenance efficiency of power system. This paper summarizes the necessity of on-line monitoring of high voltage switchgear. The traditional post-maintenance and regular maintenance mode has been difficult to meet the high requirements of reliability and availability of equipment in modern power system. By collecting the operating data of high voltage switchgear in real time, on-line monitoring technology can find the potential faults of equipment in time, provide data support for preventive maintenance and rapid fault handling, and significantly improve the safety and economy of equipment operation. This paper introduces the main content and key technology of on-line monitoring of high voltage switchgear in detail. The monitoring content covers electrical performance parameters (such as current, voltage, local discharge, etc.), mechanical characteristics parameters (such as opening and closing time, speed, displacement, etc.) and environmental parameters (such as temperature, humidity, vibration, etc.). The key technologies include sensor technology, data acquisition and processing technology, communication technology, etc. These technologies together constitute the core of high voltage switchgear online monitoring system. This paper analyzes the fault diagnosis methods and strategies of high voltage switchgear. Based on online monitoring data, data analysis, pattern recognition, artificial intelligence and other technical means are used to evaluate and predict equipment status, and identify possible fault types and locations. At the same time, the expert system and knowledge base are combined to provide scientific and reasonable suggestions and schemes for fault handling, and realize the intelligent and automatic fault diagnosis. This paper summarizes the importance of on-line monitoring and fault diagnosis technology of high voltage switchgear in power system, and looks forward to the future development trend. With the continuous progress of technology and the deepening of application, the online monitoring of high-voltage switchgear will be more comprehensive and accurate, and the fault diagnosis will be more intelligent and efficient, providing a more solid guarantee for the safe and stable operation of the power system.
