　　S11 oil-immersed transformer installation method and precautions are the issues that we should pay attention to, then let us follow the transformer factory Xiaobian to the transformer manufacturer to understand it!

　　The transformer floor has two kinds of elevation and non-elevation. When the floor is not raised, the transformer is placed on the concrete ground, and the indoor ground should be properly higher than the outdoor ground. When the floor is raised, the height of the elevation is generally 0.8m, 1.0m and 1.2m after the floor is raised, the transformer is placed on the elevated ground, and the air can be brought in below, and the height of the transformer room should also be increased accordingly. The minimum safe distance between the transformer and the room is shown in Figure 3. Where parenthesis-free size is suitable for 320kV? Transformers below A, the size in brackets is suitable for 320 ~ 1000kvV? A's transformer. When the capacity exceeds 10000V"A, and the corresponding distance is not less than 1m and 1.5m of all transformers, each S11 oil-immersed transformer shall be installed in a separate transformer room. The name and number of the transformer should be written on the door or wall of the transformer room, and there should be warning signs.

The main properties of transformer oil are as follows: (1) insulation capacity: electrical strength, the higher the better (2) Density: The density of transformer oil should be as small as possible, so that the water and impurities in the oil precipitation (3) viscosity: The viscosity of transformer oil should be moderate, too much will affect convective heat dissipation, too small will reduce the flash point (4) flash point: flash point indicates such a temperature, that is, a bit of transformer oil will flash fire. The flash point is generally not lower than 135 ° C. ⑤ Freezing point: refers to the temperature when the oil solidifies. The freezing point of transformer oil should be as low as possible. Ash and acid, alkali, sulfur and other impurities have a corrosive effect on the coil, insulation and fuel tank of electrical equipment, so the lower the content, the better. ⑦ Oxidation degree can not be too high. The degree of oxidation is usually expressed as the acid value, which refers to the amount of potassium hydroxide (mg) required to neutralize all the free acid in 1g transformer oil. The lower the acid value, the better. ⑧ Stability (also known as stability) should not be too low. Oil-filled electrical equipment and air long-term contact and heating will be oxidized into acids, resins, precipitates, etc., called aging phenomenon. Stability is the ability to resist the aging of insulating oil to maintain its original properties. The higher the stability, the better. The stability is usually expressed by the acid value and sediment content of the artificially oxidized oil, and the lower the two indicators, the higher the stability of the oil.

Well, the above is the S11 oil-immersed transformer installation method and precautions. Do you have any questions about the transformer? If you have any questions you don't understand, please continue to pay attention to our website!
