Description
Technical field
The utility model relates to transformer technology field, especially a kind of magnetic iron core being used for inverter (photovoltaic, wind energy, UPS etc.) the matching used anti-saturation transformer in field.
Background technology
The new energy fields such as current photovoltaic, wind energy, uninterrupted power supply field and energy storage field all use inverter, for low-pressure grid-connection and the inverter of powering directly to load low-voltage equipment, due to the cause of DC/AC inversion, its power frequency exports generally all exists high-frequency harmonic content and DC content, in order to harmonic carcellation is on the impact of electrical network, general inverter rear end is equipped with filter; And want to eliminate flip-flop to the impact of electrical network, then inverter rear end must increase transformer; Simultaneously in order to reduce rear end electrical network or load equipment to the impact of inverter, general transformer is safety isolating transformer; When transformer is by direct current, iron core magnetic flux density can superpose direct current component magnetic flux density again on the basis of original power frequency excitation, causes iron core easily saturated, in order to eliminate this impact, requires that the iron core of transformer is provided with air gap.
At present, general transformer adopts and is divided into monoblock stem stem and monoblock iron yoke two parts to carry out docking closed assembly iron core, in iron yoke and stem stem interface, air gap plate is set, the iron core of said structure design, its iron yoke is separated completely with stem stem, and the reliability of iron core mainly ensures by outer structural parts, adds the reliability requirement to structural member, and this iron core, be easy to produce noise due to vibrations in iron core excitation process.
Therefore, prior art needs to be improved and improves.
Summary of the invention
For the deficiencies in the prior art part, the purpose of this utility model is to provide the magnetic iron core for anti-saturation transformer that a kind of structure is simply firm, reasonable in design, can effectively avoid noise to produce.
For achieving the above object, the technical scheme that the utility model adopts is:
For a magnetic iron core for anti-saturation transformer, comprise several first core assemblies and several second core assemblies of adjacent spaces setting, described second core assembly is identical with inverted first core assembly structure; Described first core assembly is in the font of falling day, to comprise on first horizontal iron yoke monomer on horizontal iron yoke monomer, second, lower horizontal iron yoke monomer, left vertically stem stem monomer, in perpendicular stem stem monomer and the right side erect stem stem monomer, in described, the upper end bilateral symmetry of perpendicular stem stem monomer is provided with horizontal iron yoke monomer and the second horizontal iron yoke monomer on first; The two ends of described lower horizontal iron yoke monomer are arranged with left vertically stem stem monomer and vertical right stem stem monomer; On the upper surface and first of a described left side vertical stem stem monomer between horizontal iron yoke monomer, on the upper surface and second of right vertically stem stem monomer between horizontal iron yoke monomer, in be vertically respectively equipped with the first air gap plate, interstice plate and the 3rd air gap plate between the lower surface of stem stem monomer and lower horizontal iron yoke monomer.
Compared with prior art, the beneficial effects of the utility model are: owing to adopting above-mentioned structural design, namely horizontal iron yoke monomer and vertical stem stem interlock closed assembly, horizontal iron yoke monomer and vertical stem stem monomer docking location arrange air gap plate, the fastness of structure and the placement of air gap plate have not only been taken into account simultaneously, and effectively can avoid the generation of iron core noise, improve performance and the life-span of product.
