Main use of mining transformers

First, the use of power mining transformers

Power mining transformers are available in both boost and buck. In power systems, its main uses are as follows:

1. When the power system is transmitting power over long distances, when the power of the transmitted power and the power factor of the load are constant, the higher the voltage, the smaller the current of the line, which not only reduces the cross-sectional area of ​​the transmission line, but also saves materials, and can also Reduce power loss on the line. Therefore, the transformer must be used to increase the voltage during long-distance transmission.

2. When the electric energy is delivered to the power consumption area, in order to properly distribute and safely use the electric energy, the voltage drop must be reduced by the step-down transformer and distributed to each user, so that the user can obtain the rated voltage they need.

3. The power mine transformer can also be used as a tie transformer, that is, two or more grids with different voltages are connected together.

Second, the type of power mining transformer

1. According to the purpose of the transformer, there are step-up transformers, step-down transformers, distribution transformers, tie transformers, power transformers for power plants, etc.

2. According to the structure of the transformer, there are autotransformer, double winding transformer and three winding transformer.

3. According to the rated capacity of the transformer, there are small transformers with rated capacity less than or equal to 630kvL, medium-sized transformers with rated capacity of 800-6300kvL, large transformers with rated capacity of 8000kvL-63000kvL, and extra large transformers with rated capacity above 90000kvL. .

In addition, the transformer can be classified according to its phase number, cooling method, wire material used in the winding, and voltage regulation mode of the transformer.
