Description

technical field [0001] The invention relates to the technical field of smart grid power equipment monitoring, in particular to an optical fiber-based high-voltage closed bus online monitoring and management system. Background technique [0002] In recent years, with the rapid rise of my country's industry, the demand for electricity in all walks of life has also increased, and the load on power plants has also increased. The closed busbar is the heavy pressure equipment of the power plant, and its operating condition directly affects the normal operation of the entire power plant. During the long-term full-load operation of these devices, it is inevitable that heat, temperature rise, and condensation will occur. Excessive temperature will affect the power supply of the power plant and even cause accidents. Therefore, monitoring the temperature and humidity of the closed bus is fundamental to prevent such accidents. However, the closed busbars of each phase are closed and c...

AI Technical Summary

Problems solved by technology

However, the closed busbars of each phase are closed and charged at high voltage, so the traditional method of workers' inspection and temperature detection is difficult to meet the requirements

For example, the process management of the high-voltage closed busbar system in thermal power plants still relies on the original manual and infrared monitoring in most power plants, which is easily restricted by time, place and scope

There are many uncertain factors objectively, and there are still many deficiencies in equipment management
