A thin copper foil is grounded between the primary winding and the secondary winding of the transformer, which can prevent the second harmonic contained in the primary power supply from entering the secondary winding, and is widely used in electronic equipment.
Isolation transformers, as the name suggests, are mainly used to isolate electrical equipment from the power grid.
For safety applications or anti-interference requirements, there is no direct electrical connection between electrical equipment and the power supply. Isolated structural materials are expensive and expensive.
In addition to changing the voltage, the input winding and output winding can be electrically isolated from each other, and the input/output and neutral wires can be isolated to avoid simultaneous contact with charged objects (or metal parts that may be charged due to charging). Insulation damage) and grounding. The danger it brings.
In addition, the isolation transformer also has a certain effect of suppressing various interferences, with filtering performance and high safety.
