在发电厂和变电站中，用于向电力系统或用户输送功率的变压器，称为主变压器

In power plants and substations, the transformer used to transmit power to the power system or users is called the main transformer, and the transformer used to exchange power at two voltage levels is called the contact transformer. Transformer is one of the main electrical equipment in substations. It plays an important role in delivering power to users or exchanging power between two voltage levels. At the same time, considering the growth of power system load, a reasonable choice is required. Otherwise, it will cause economic and technological problems. Unreasonable.

In power plants and substations, transformers used to transmit power to power systems or users, called primary transformers, transformers used for two voltage levels to exchange power, called contact transformers. Transformer is one of the main electrical equipment in substation, which serves as an important task of transmitting power to users, or exchanging power between two voltage levels, taking into account the load growth of power system, it needs to be reasonable to choose, otherwise, it will cause economic and technical irrationality.

In power plants and substations, the transformer used to transmit power to the power system or users is called the main transformer, and the transformer used to exchange power between two voltage levels is called the interconnection transformer. Transformer is one of the main electrical equipment in substation. It is an important task to transfer power to users, or exchange power between two voltage levels. At the same time, considering the load growth of power system, it needs to be selected reasonably. Otherwise, it will cause economic and technical irrationality.
