The role of the transformer core coated insulating paint! 2019 - 03 - 30 15:05:17 transformer core coated insulating paint: the effect of the magnetic circuit of transformer core transformer, and the body skeleton role at the same time. Transformer core with 0. 35 mm thick, coating the surface of the insulating varnish superposition of silicon steel sheet. Core coated insulating varnish is mainly in order to reduce the core loss: 1, silicon steel sheet itself is conductive, in under the action of magnetic flux exchange, also produced the induced current in the core. 2, if the core is not coated insulating paint, core will become a whole, rather then a very large area of the conductor and its resistance value is small, although the induction voltage is not high, but the induced current is very large. It will produce great vortex ( Circulation) Wear and tear. Serious when, can make the core hot melt even rust, known as the core & other; Fire & throughout; 。 3, after coating insulating paint, between each core is divided into many small section of the conductor. So its resistance. The core of the paint, although there is also a eddy current loss ( Part of the iron loss) But much smaller. 4, therefore, silicon steel sheet is thinner and with insulating varnish.
