Background
The transformer is a main power device applied to a power grid and a power system, the transformer is a device for changing alternating voltage by using the principle of electromagnetic induction, and mainly has the functions of realizing voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization and the like, and the transformer mainly comprises an iron core (or a magnetic material) and a coil. Classified by core structure, they are mainly classified into laminated cores and wound cores.
The laminated core is generally of a planar arrangement type, and may be divided into a core type and a shell type. The core column section of the core type transformer is circular, the placing mode is vertical, the coil section is also circular, the high, medium and low voltage coils are sequentially and concentrically sleeved on the core column, the coils surround the core, and the coils are concentrically arranged. The shell type transformer iron core has a plurality of structures, coils are surrounded by the iron core, the section of an iron core column is rectangular, an iron core lamination is only one sheet wide, a plurality of iron core sheets are overlapped to form a certain thickness, the external connection shape of the section of the iron core column is rectangular, the iron core column is placed horizontally, side iron yokes are arranged on two sides of the iron core column, the iron cores surround the coils, and the coils are arranged in a staggered mode.
The laminated iron core has the main advantages of simple structure, convenience for standardization and universalization, namely, core type and shell type; however, the main disadvantage is that because the yoke and the core leg are assembled in butt joint (i.e. the core is formed by splicing), and because each core leg is composed of two separated parts, under high magnetic density, when magnetic flux passes through the separated parts, the magnetic field is not uniform, and noise vibration and other adverse effects are generated on the idle load performance. To alleviate this effect, the core leg cross-sectional area should be increased appropriately, but this will result in an increase in the amount of material used.
The wound iron core is wound along the optimal magnetic conduction direction of the oriented silicon steel sheet, the superior performance of the oriented silicon steel sheet is fully and fully exerted, the magnetic circuit distortion is small, and no seam and no air gap exist; each frame is a closed magnetic circuit conductor, and the orientation performance of the cold-rolled silicon steel sheet can be fully exerted, so that the no-load performance is obviously improved. Particularly, the especially-power component in the no-load current is obviously reduced, the power factor can be improved, and the power supply quality of a power grid is improved. However, the requirement of the iron core winding process is high, the molds for winding the iron core first and winding the winding later are not easy to generalize, the mold filling and demolding processes are complex, the manufacturing difficulty of the transformer with the laminated iron core is high, the maintainability is weaker than that of the transformer with the laminated iron core, and the like.
The novel transformer which saves energy and reduces consumption, saves materials, has low cost, is environment-friendly and has low noise is manufactured, and the structure of the iron core is improved to form a breakthrough. The process of the wound core is similar to the core type structure of the laminated core, and the wound core is a coil wound core and can be called a wound core type transformer. And the utility model discloses a novel single-phase energy-saving transformer is a wound form shell type transformer and rolls up the structure of unshakable in one's determination (wound form heart type transformer) on the contrary, twines the winding earlier, and the back is around magnetic material, not only possesses all advantages of rolling up unshakable in one's determination, and is simple in manufacturing process, can utilize current technology, mould to realize automated production. The wound shell type transformer has more excellent structural advantages, more excellent energy-saving performance and more advantageous cost, and is the most ideal transformer at present.
