Ring transformer shielding cover, what are the applications of the shielding layer +15 years of shielding cover manufacturers to show you

The technical staff responsible for the manufacturer of the shielding cover of the ring transformer said that the following aspects must be paid attention to after the design of the shielding layer of the high-frequency transformer is completed to ensure the effect of the application. The novel has sorted out some information, and let’s take a look at it below: First of all, for the internal shielding layer of a high-frequency transformer, the main function is not to shield the leakage magnetic field, but to shield the primary and secondary high-frequency electric field signals, so the high-frequency The main function of the transformer shielding layer is to connect to a quiet potential to ensure the connection effect of the primary side ground wire and the connection effect of the high voltage end. If the copper foil shield cuts off the path of the primary and secondary stray capacitance, it will form a capacitance. When the winding shield cuts off the primary electrophoresis path, due to the difference in the number of winding turns, the effect on the winding direction and position will be very obvious. difference. It can effectively enhance the shielding effect, so the thickness of the copper foil is generally about 0.05 mm, and the width should be smaller than the width of the primary winding. Through this design method, it can be ensured that there is no short circuit at both ends of the shielding layer. In the production process, both ends of the copper foil must be insulated with insulating tape. In the process of using the winding as the inner shield, 0.1 mm~0.3 mm enameled wire must be used for meticulous winding, and the insulating tape must be used to fix the closing position. Can enhance the insulation effect of the shielding layer. In the process of designing the shielding case, since the attenuation of the shielding material must be measured according to the magnetic field strength to obtain data, the most suitable shielding case must be selected. Generally speaking, the shape of the shielding cover such as rectangle, cylinder rectangle, sphere, etc. is the most common. The magnetic flux density value must be determined when designing the shielding cover, because the distribution of the shielding material is a non-linear relationship. If the strength is relatively high or the material closest to the magnetic field should be made of multilayer materials, the secondary material should be made of high permeability materials.
