The design of a switch mode power transformer will differ depending upon the type of circuit used. There are many variations of switching mode power supplies, but they can be narrowed down to three basic circuit configurations (each also has a mirrored configuration); buck, boost, and fly back. Be aware that the name for the buck circuit varies from industry to industry and from person to person. It may also be referred to as an inverter, d.C. Converter, forward converter, feed forward, and others. There are also unipolar and bipolar (push-pull) versions.

Power Transformer (35kV) Oil-immersed Transformer Products structure and technical features The oil-immersed transformer produced by our factory have these advantages: low loss, low noise, high short circuit strength and good appearance. We company create these prefect products of that each parameter has reached to advanced level among domestic similar products by combining advanced manufacture equipments and technology. Structure features: Core and main body: it is used iron core cutting line ,all inclined ladder joints and improving flux trend to eliminate flux saturation phenomenon of iron core in joints . By doing these, it reduces the no-load loss, no-load current and noise of transformers. Adopting pulling-plank structure, in order to strengthen the ability of withstanding short-circuit, we put many nails around pressing planks and bracing plates are used as support between H.V and L.V yoke, make the iron core be a whole. The iron core sheet are coated by glue which are specialized for silicon steel , so that all silicon steels can be bonded together to make the iron core be  integral one, this effectively enhances mechanical strength and plays a positive role in the core anti-rust. The low part of the body and the oil tank are supported through bracing plates adopt" high intensity electric laminated" technology, to guarantee the low part of oil-immersed transformer's body safe and reliable. Coil: The high-voltage(HV) coil adopts an interleaved-continuous structure, The low-voltage(LV) coil adopts an interleaved-continuous or spiral structure, are independently provided with voltage-regulating winding to balance the ampere turn of each winding-up, effectively lower the mechanical force to minimal level. In the transformer winding, there is a zigzag oil guide structure so as to fully cool all areas inside the winding, lower the temperature rise of the winding and the hot points of the winding and prolong the service life of insulation. Oil tank: the tank's structure of oil-immersed transformer is bell jar type or suspended type, have a good looking and high mechanical strength. It adopts" flanged joint" technology in every key point (such as annular tubes, pressure valves, switches,etc.), which effectively avoid leaking oil.

L.V side is equipped with double-split winding and two outlets which can be connected with two PV generators at the same time, meanwhile, equipped with essential protective electric elements. This series of products are with characteristics of good electrical performance, small size, light weight, reliable operation, easy to install, high cost-effective, etc. Features of productsâ?? structure a, design thought: adoptsâ?� two generators, one transformerâ?� program, means two PV generators combines with one transformer. L.V side is equipped with double-split winding ,two outlets and L.V electric system which can be connected with two PV generators at the same time. b, users can rise one transformerâ??s output capacity under the capacity of same generators, which can save usersâ?? investment and operational cost. c, materials of transformersâ?? casings can be chosen according to different environmental requirements: conventional composite panels, stainless steel composite panels, non-metallic fiberglass cement, etc. d, casing material has a good level of protection and corrosion resistance, which can effectively prevent wind, rain, snow and salt erosion e, H.V. electrical equipments have five protection functions: H.V. fuse of substations and overload switchgear carry out interactive protection, prevent transformers working under the condition of lacking phase; H.V use three-position load switch that can be checked and repaired safely under the state of grounding; H.V overload switch and grid door of transformer chamber adopt â?? electric locking, realize the protection function of automatic power-off when mistakenly open the grid door. f, transformer chamber adopts natural ventilation and automatic controlling forced cooling exhaust devices, has a exhaust system which can be controlled automatically with temperature change, can effectively control and low chamberâ??s temperature, meet the need of full overload operation. g, low voltage equips with 690V main circuit breakers, over-voltage protection equipments , and we can design complete automatic measurement and intelligent control systems.
