Cast Resin Electrical Transformers Components

The components of cast resin electrical transformers include body, iron core, winding resistance, insulation layer, wire, oil tank and refrigeration equipment, transformer equipment, protection equipment, moisture absorber, safety gas pipe, gas relay, oil storage tank and temperature measurement equipment and casing. Actual composition and function:

(1) cast resin electrical transformers core. The iron core is an important part of the dry-type transformer. It is usually composed of hot-rolled steel or hot-rolled ferrite cores with high silicon content, thickness of 0.35mm, 0.3mm, and 0.27mm respectively, and the surface is coated with conformal paint. The dry-type transformer core is divided into two parts: the dry-type transformer core column and the horizontal piece. The cast resin electrical transformers core column is sleeved with winding resistance, and the horizontal piece is used to close the equivalent circuit.

(2) Winding resistance. The winding is a part of the power supply circuit of the dry-type transformer, which is wound with a double-wire insulated flat wire and an enameled round wire. The basic principle of the cast resin electrical transformers is the magnetic effect of the current. Now, the single-phase electric double-winding dry-type transformer is used as an example to illustrate its main principle: when the primary side winding is added with the working voltage U1, the current I1 passes through, In the cast resin electrical transformers iron core, the alternating magnetic flux O1 is caused, which is called the dominant magnetic flux.
