Description

Novel transformer structure Technical Field The utility model relates to the field of transformer structures, in particular to a novel transformer structure. Background A transformer is a device that changes an ac voltage by using the principle of electromagnetic induction, and plays an important role in a power system. They are not only used for voltage conversion during power transmission and distribution, but also in relation to stability and safety of the whole power system. However, although the conventional distribution transformer can meet basic transformation requirements, the conventional distribution transformer has disadvantages in terms of power quality adjustment, insulation strength, manufacturing efficiency and the like. However, the electronic transformer has a regulating function, but has high cost, and cannot meet the requirements of the transformer for both power distribution and regulating functions and lower cost. Disclosure of utility model The utility model aims to provide a novel transformer structure, which can solve the defects of the traditional distribution transformer in the aspects of electric energy quality adjustment, insulation strength, manufacturing efficiency and the like through innovative design, realize the compromise of distribution and adjustment functions and reduce the production cost so as to meet the actual demands of the market. The transformer structure comprises a first magnetic yoke ring, a second magnetic yoke ring and a third magnetic yoke ring which are arranged in parallel, wherein a plurality of first magnetic columns are arranged between the first magnetic yoke ring and the second magnetic yoke ring, a plurality of second magnetic columns are arranged between the second magnetic yoke ring and the third magnetic yoke ring, and coils are wound on the first magnetic columns and the second magnetic columns. In some embodiments, the first yoke ring, the second yoke ring, and the third yoke ring are triangular in cross-section. In some embodiments, the first magnetic columns are three and are arranged at three corners of the first magnetic columns, and the second magnetic columns are three and are arranged at three corners of the second magnetic columns. In some embodiments, the first yoke ring, the second yoke ring, and the third yoke ring are each rolled from amorphous ribbon. In some embodiments, the first magnetic pole and the second magnetic pole are iron core poles formed by stacking silicon steel. In some embodiments, the core limb is cylindrical. In some embodiments, the height of the second magnetic pillar is greater than the height of the first magnetic pillar. In some embodiments, the ratio of the magnetic flux of the first yoke ring, the second yoke ring, and the third yoke ring to the magnetic flux of the first magnetic post, the second magnetic post is 0.45 to 0.73. In summary, the utility model has the following beneficial effects: this kind of new transformer structure is connected through a plurality of first magnetic columns, second magnetic column between first magnetic column, second magnetic column, the third magnetic yoke ring, and twine the coil on first magnetic column, the second magnetic column, can realize the distribution function of transformer, through twining the coil of different turns on first magnetic column and second magnetic column, can realize the accurate regulation to output voltage and electric current, thereby realize the regulatory function of transformer, and then realize the compromise of distribution and regulatory function, first magnetic yoke ring simultaneously, second magnetic yoke ring, third magnetic yoke ring adopts amorphous strip material to roll up to form, first magnetic column, second magnetic column adopts the silicon steel sheet to pile up to form, can make the transformer have higher dielectric strength and anti short circuit ability, and can make first magnetic yoke ring, second magnetic yoke ring, third magnetic yoke ring, coil coiling go on simultaneously, thereby solve the defect of traditional distribution transformer in aspects such as electric energy quality regulation, dielectric strength, manufacturing efficiency, reduction in turn to the manufacturing cost, and then satisfy market's actual demand.
