Abstract

The invention discloses a method for overhauling oil-immersed high-voltage equipment, which includes: establishing an insulating oil performance degradation database for oil-immersed high-voltage equipment; Mathematical model for fault detection and prediction; obtain various oily data of insulating oil in the oil-immersed high-voltage equipment to be overhauled; perform fault detection on the oil-immersed high-voltage equipment to be overhauled according to the mathematical model and the oily data and prediction; according to the results of the fault detection and prediction, corresponding maintenance is performed on the oil-immersed high-voltage equipment to be repaired. In addition, an oil-immersed high-voltage equipment maintenance device is also disclosed. The present invention can effectively improve the accuracy of equipment failure detection, accurately release failure warning information, thereby more accurately guiding maintenance time, reasonably arranging and shortening power failure maintenance time, and greatly saving oil-immersed high-voltage equipment while improving equipment utilization. Overhaul costs.

Description

technical field [0001] The invention relates to the technical field of oil-immersed high-voltage equipment, in particular to an oil-immersed high-voltage equipment maintenance method and an oil-immersed high-voltage equipment maintenance device. Background technique [0002] As the scale of the interconnected grid doubles, it is more likely to cause large-scale cascading blackouts due to local equipment failures. Once a large-scale power outage occurs in the power grid, in addition to causing major economic losses, it may also endanger public safety and social stability. At present, the methods to deal with this cascading failure focus on prevention, reduce the probability of accidents from the source, and control the impact within a small range. [0003] The safety of the power grid is mainly reflected in two aspects: the safety of power equipment and the safety of system operation, and the safe operation of power equipment is the basis of system security. Oil-immersed hi...
