Description

Technical Field

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the purpose, it can be divided into: power transformers and special transformers. The installation height of the transformer is generally about 1.8 meters, but the specific height should be determined according to the power, model, purpose and other factors of the transformer. For example, transformers in urban residential areas are generally required to be installed at a height of not less than 2.5 meters. Transformers installed indoors should be no less than 1.8 meters from the ground; transformers installed outdoors should be no less than 2.5 meters from the ground.
