Utilization of transformer

Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core (magnetic core). Main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.

Transformer can be divided into distribution transformer, power transformer, fully sealed transformer, combined transformer, dry-type transformer, oil-immersed transformer, single-phase transformer, furnace transformer, rectifier transformer, reactor, anti-interference transformer, lightning protection transformer, box-type transformer test transformer, corner transformer, high-current transformer, excitation transformer, etc.

Transformer is the basic equipment of power transmission and distribution, which is widely used in industries, agriculture, transportation, urban communities and other fields. There are about 17 million transformers in operation in China, with a total capacity of about 11 billion KVA. Transformer loss accounts for about 40% of the power loss of transmission and distribution, which has great energy saving potential. Accelerate the promotion and application of high-efficiency energy-saving transformers, improve the efficiency of energy and resources utilization, and promote green, low-carbon and high-quality development.
