Transformer-What is the main purpose of the transformer?

Isolation transformer
Electrical isolation-in addition to maintaining machinery and equipment, but also to maintain life safety! Protection against risk voltage. Prevent some accidents. The isolation transformer's output and input-capacitance coupling is small, which can suppress the effects of lightning strikes, charging and discharging, grid conversion, motor starting and other grid dryness. From this perspective, isolation transformers are a large number of maintenance machinery and equipment.

Power Engineering Transformer
A power engineering transformer is a static data electrical device used to change a certain value of AC voltage (amount of current) to another or a variety of different voltages (amount of current) of the same frequency. Power engineering transformers are power plants and One of the key equipment of power distribution station, blood pressure lowering transformer, transformer transformer
The key role is the voltage conversion, the voltage increase or decrease the maximum power of the transformer.
Three-phase transformer
According to the selection of the coupling group, it also has the effect of suppressing the third harmonic (mainly the triangular interface method, the third harmonic is consumed in the no-load control loop), and the leakage inductance of the transformer is used to develop the filter. What is the key role of the transformer?
The most important function or voltage conversion, voltage increase or decrease
Classification: transformer transformer, blood pressure lowering transformer
2) It is only used for safety protection. When the primary side or the secondary side is invalid, it does not harm the correlation between the turns of the transformer coil and the voltage on the other side.
1:1 isolation transformer transformer is a kind of changeable.
The three-phase transformer, according to the selection of the coupling group, also has the effect of suppressing the third harmonic
