Rectifier transformer
Product Features:
The transformer used as the power supply of rectifier is called rectifier transformer. Our company uses the world's advanced transformer design technology and manufacturing process, and adopts the programmed design to analyze and quantitatively calculate the dielectric breakdown mechanism, electric field numerical analysis and insulation technology, wave process impact characteristics of winding, and anti sudden short circuit strength. Integrating our company's experience of rectifier transformer manufacturing for many years, we made a great breakthrough on the basis of traditional technology, thus further improving the reliability and advanced nature of products.
Structure features
(1) Iron core: 30Q130 high magnetic conducting silicon steel sheet is adopted, and 3-6-step multi-stage lamination mode is adopted at the same time, which can reduce no-load loss, no-load current and noise.
(2) Winding: the high conductivity oxygen free copper conductor is used for the electromagnetic wire, and the whole package new technology of cylinder, double pie and new spiral structure is used for the winding, which makes the product structure more compact, the main insulation can be guaranteed effectively, the first and last layers are strengthened, and the insulation performance is improved. The winding outer surface is wrapped with high-strength compact tape, which improves the mechanical strength of the winding and greatly improves the impact resistance and short-circuit resistance of the product.
(3) Body: the insulation cushion block of the body is supported by high-strength laminated wood and laminated cardboard, so that the support area of the end of the winding reaches more than 95%, further improving the anti-short circuit ability of the product, and improving the operation reliability of the product. The connection between the body and the box cover adopts a mechanical buffer structure, which overcomes the phenomenon of "hanging" and "top cover" of the body. The insulating materials shall be wrapped with high-strength and high-density cable paper, and the allowable pressure shall be 45Mpa.
(4) Oil tank: the oil tank adopts heat dissipation oil pipe (double row and three row oil pipes adopt the way of inserting piece), or adopts step type radiator, which increases the heat dissipation capacity under the same tank wall area; it can also be calculated to install plate type radiator or corrugated oil tank according to the user's requirements, and strong oil air cooling or strong oil water cooling radiator. Surface treatment of oil tank: the transformer shell is painted with "three anti paint" (anti salt fog, anti damp heat and anti mildew), which has strong adhesion with primer, good decoration, film oil resistance, corrosion resistance, light retention and color retention, and good leveling and covering power.
