Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are primary coils, secondary coils and iron cores (magnetic cores).The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage voltage (magnetic saturation transformer), etc.
DC transformer symbol
Take the symbol above a picture as an example, explain to you, the specific picture is below the table.

DC transformer model
In recent years, the country has developed three new types of energy -saving transformers, namely: S8, S9, and S11. Among themThe density and the cross section of the wires are increased, thereby reducing the density of winding current, greatly reducing the load loss and empty load loss. The S11 series transformer improves the structure design on the basis of the S9 series.It is developed further by reducing the air load loss. Considering it from cost -effective, when new or transformers are newly built or transformed, the S9 low -loss transformer should be selected.
DC transformer principle
The saying of DC transformers is inaccurate. First, DC voltage voltage uses electronic components to become AC power, and then changes the voltage through the transformer. This is called inverter. The working principle of the working principle of the device used to boost the DC power voltage is used.Electromagnetic induction principle work.There are two sets of coils in the transformer.Primary coils and secondary coils.The secondary coil is outside the primary coil.When the primary coil is connected, the transformer core generates an interchange magnetic field, and the secondary coil will produce inductive electrical momentum.The turning ratio of the coil of the transformer is equal to the voltage ratio.
