Baoding oil-immersed transformer in the daily operation because of the role of no-load loss and load loss, will inevitably make baoding oil-immersed transformer heat, heat by conduction, convection and radiation emitted from the way into the surrounding cooling medium, a fever, a cooling, if the fever is greater than the heat dissipation in all parts of baoding oil-immersed transformer temperature will rise up, heating and heat balance temperature keep a certain value, and no longer increases, then the stability of the temperature is usually referred to in baoding oil-immersed transformer temperature of each part. Generally speaking, the bigger the oil-immersed transformer's heating and the smaller the heat dissipation, the higher the temperature will be.

 

On the whole, the heat of baoding oil-immersed transformer mainly comes from the iron core and windings, and only when there is a certain temperature difference will the heat dissipation. Therefore, the temperature of each part of the transformer is different. The temperature of winding is usually the highest, followed by that of iron core. The temperature varies from top to bottom, but the highest temperature is not the highest because of better heat dissipation.

 

Features of oil-immersed transformer:

1. High reliability, advanced performance level and reasonable economic indicators.

2. The iron core adopts step trapezoidal three-stage joint, and the surface is coated with solidified paint to reduce loss and noise.

3. New winding structure, reasonable oil channel design and new insulation structure are adopted to improve mechanical strength and short-circuit resistance.

4. Diversified, beautiful and generous oil tank. Working parameters: input/output voltage: : (required) according to the requirements of rated frequency 50 hz or 60 hz electric strength: 2.5 KV / 60 s insulation resistance: > 20 m Ω/DC500V insulation class: class A, 105 ℃ cooling way is: oil cold connection mode: from lotus root: Y type, isolation: : train/Y (other connection mode in order to indicate) capacity range: 10 kva - baoding oil-immersed transformer of 2000 kva

Conditions of use

1. Elevation shall not exceed 1000m indoor or outdoor

2. The highest temperature + 40 ℃, the average temperature + 30 ℃

3. The highest average annual temperature + minimum temperature 20 ℃ to 25 ℃

4. Special operating conditions can be provided as required

 

It is normal for baoding oil-immersed transformer to have heating in daily operation. However, it is worth noting that in order to ensure the normal operation of baoding oil-immersed transformer, regular inspection is carried out on oil-immersed transformer so as to find out problems in time and solve them.
