Problems solved by technology
[0006] In order to overcome the above-mentioned problems in the prior art, the object of the present invention is to provide a bushing type transformer oil heating device and method based on the principle of electromagnetic induction heating, which can make the heating device The transformer oil flowing inside is evenly heated, which improves the temperature uniformity of the transformer oil during the heating process. Under the condition of ensuring that the heating temperature is lower than the temperature at which the transformer oil deteriorates, the limit of the maximum electromagnetic induction heating power is increased to reduce the circulation and drying of hot oil. The heating time of transformer oil during the transformer process saves time and cost

The invention discloses a sleeve type transformer oil heating device and method based on an electromagnetic induction heating principle. A sleeve type electromagnetic induction heating device is used,so the electromagnetic induction heating performance in the circulation process of the transformer oil is improved, the temperature uniformity in the heating process is good, the heat transfer performance of the transformer oil in the heating device is enhanced, the maximum electromagnetic induction heating power is improved under the condition of avoiding deterioration of the transformer oil, the time cost of cyclic heating of the transformer oil is saved, and the temperature uniformity of heating of the transformer oil is improved.
Description
technical field [0001] The invention relates to the technical field of transformer oil heating, in particular to a bushing type transformer oil heating device and method based on the principle of electromagnetic induction heating. Background technique [0002] The necessity of transformer oil heating cycle: During the transportation, installation and maintenance of the transformer and the humid air environment will cause water seepage in the transformer, reduce the insulation of the transformer, and reduce the breakdown voltage of the transformer. However, the damage of the transformer is largely Both are due to the degradation of the insulation performance caused by the water seepage of the transformer, resulting in the breakdown of the transformer. Therefore, before the transformer is put into use, it is necessary to measure the insulation of the transformer. When it is judged that the insulation of the transformer does not meet the use standards, the transformer oil needs...
