Defect rate detecting method of oil immersed type main transformer

Abstract

The invention provides a defect rate detecting method of an oil immersed type main transformer. The defect rate detecting method includes obtaining determinant attributes of the oil immersed type main transformer serving as a sample through detection, establishing a regression model of the determinant attributes and a defect rate of a device, and accurately predicting the defect rate of an oil immersed type main transformer to be detected by means of the regression model and the determinant attributes of the oil immersed type main transformer to be detected. The defect rate reflects the whole defect level of the oil immersed type main transformer of power grids, and various defects in power equipment can be early found and timely eliminated, so that the phenomenon that large-scale loss of power failure of the power grids is caused by the fact that the defects are developed into faults is avoided. According to defect rate differences among different kinds of the devices, maintainers can purposefully perform focused inspection and maintenance to prevent the defects from developing into device faults; production departments can formulate production personnel plans and spare part requirements and predict a future change trend of the defect rate of the devices in combination of development planning of the power grids to guide producing activities of the power grids to well develop.

Description

technical field [0001] The invention relates to the field of power system detection technology, in particular to a defect rate detection method of an oil-immersed main transformer. Background technique [0002] With the continuous development and progress of social economy and cultural life, the city's dependence on electricity is like the relationship between fish and water. Without electricity supply, the transportation, production and life of the whole city will be paralyzed. Panic and huge losses are difficult to estimate. Power equipment is the basis for grid operation and ensuring power supply. Reliable power supply and efficient operation of the grid are based on the premise of healthy and reliable operation of power equipment. Defect detection of power equipment is an important means to improve equipment reliability and availability. Key areas of oil-immersed main transformer equipment management. [0003] The defect rate of power equipment reflects the overall def...

AI Technical Summary

Problems solved by technology

[0003] The defect rate of power equipment reflects the overall defect level of oil-immersed main transformer equipment in the power grid. For various defects in power equipment, it is necessary to find and eliminate them as soon as possible, so as to avoid defects from developing into faults and causing large-scale losses such as power grid outages.
