Dry Transformer's temperature control system and protection method

The safe operation and service life of the Dry Transformer largely depends on the safety and reliability of the transformer winding insulation. The winding temperature exceeds the insulation withstand temperature and the insulation is damaged, which is one of the main reasons that the transformer cannot work normally. Therefore, it's vital to watch the operational temperature of the electrical device and its alarm management. Therefore, the temperature control system must be considered when a Dry Transformer is selected. Then let's take a look at the temperature control system and protection methods of the Dry Transformer. Here are some answers.

Structural classification of oil-immersed transformer

The oil-immersed transformer can be divided into iron core type oil-immersed transformer and iron shell-type transformer. If the winding is wrapped around the iron core, it is an iron-core type oil-immersed transformer. For example, the core is wrapped around the winding, and the oil-immersed transformer is an iron-shell type. The two are just slightly different in structure, and there is no essential difference in principle. The oil-immersed transformer is mainly composed of an iron core, winding, oil tank, oil pillow, insulating sleeve, tap changer, and gas relay. Next, let us take a look at the structure classification of transformer.

How the oil-immersed transformer performs oil treatment

The Oil-immersed transformer can be used indoors (outdoors) and can be installed on poles when the capacity is 315kVA and below. The ambient temperature is not higher than 40℃ and not lower than -25℃. The highest daily average temperature of an transformer is 30℃. The highest annual average temperature is 20℃, the relative humidity does not exceed 90% (ambient temperature is 25℃), and the altitude does not exceed 1000m. In daily production and life, how does the Oil-immersed transformer process oil? Let's take a look together next.
