[0002] Immersed transformers are common equipment in power systems, used to convert high-voltage electricity into low-voltage electricity or vice versa. During operation, the insulating oil inside the transformer plays a role of cooling and insulation to ensure the normal operation of the transformer. However, as the operating time of the transformer increases, the insulating oil inside the transformer will gradually be contaminated and oxidized, causing the transformer performance to deteriorate or even be damaged. In order to ensure the normal operation of the transformer and extend its service life, the filter element inside the transformer needs to be replaced regularly to remove pollutants and keep the oil clean. Traditional oil-immersed transformers require tedious operations such as shutting down the transformer, emptying the oil tank, and removing the filter element when replacing the filter element. This is not only time-consuming and labor-intensive, but also prone to oil leakage and safety hazards. In addition, it cannot ensure that the filter element is installed in the correct position, and cannot prevent the filter element from shaking or shifting during use to prevent leakage.
