Material detection method, device and computer equipment for transformer winding

Abstract

The present application relates to a material detection method, device, computer equipment and storage medium of a transformer winding. The method includes: acquiring capacity data and winding size data of the transformer, inputting the capacity data and winding size data of the transformer into an evaluation model, and generating evaluation results. According to the evaluation result, the aluminum-containing probability of the transformer winding is obtained, and according to the aluminum-containing probability of the transformer winding, the material detection result of the transformer winding is obtained. This method only needs to input the capacity data and winding size data of the transformer into the evaluation model to obtain the aluminum-containing probability of the transformer winding. It does not need to go through a series of complicated processes and use special instruments for manual calculation, which improves the transformer winding. The calculation efficiency of the aluminum-containing probability further improves the material determination efficiency of the transformer winding.

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to a material detection method, device, computer equipment and storage medium for transformer windings. Background technique [0002] With the development of power technology, power transformers are used more and more widely. Power transformers are devices that use the principle of electromagnetic induction to change AC power. When the power supply bureau checks and accepts the dry-type transformers of the distribution network and the dry-type transformers of the special transformer users (referring to users who purchase and use the transformers), or the users themselves check and accept the dry-type transformers, due to the lack of transformer knowledge of most users, it leads to In the event that the winding material cannot be detected correctly, it is possible to receive a transformer whose winding material is aluminum instead of copper or copper-clad aluminum. ...

When the power supply bureau checks and accepts the dry-type transformers of the distribution network and the dry-type transformers of the special transformer users (referring to users who purchase and use the transformers), or the users themselves check and accept the dry-type transformers, due to the lack of transformer knowledge of most users, it leads to In the event that the winding material cannot be detected correctly, it is possible to receive a transformer whose winding material is aluminum instead of copper or copper-clad aluminum. However, due to the poor thermal stability of aluminum and the shortcomings of easy burning, it will greatly reduce the dry type of the distribution network. The life of the transformer affects the safe and stable operation of the distribution network, so it is necessary to judge the winding material of the transformer to control the quality of the transformer and avoid affecting the stable operation of the distribution network

[0003] The traditional judgment method, when judging copper and aluminum transformers, requires special instruments to do DC resistance and other experiments on dry-type transformers. The problem of low efficiency
