Abstract
The utility model relates to a reactor, which is used on a power system. A structure of the utility model comprises an iron yoke 3 and an iron yoke 4 which are made in ferromagnetic materials, a coil 1, a coil 2, and a clamping piece 5 for positioning and clamping. The coil 1 and the coil 2 are connected in series. When the coil 1 and the coil 2 pass by alternating current, the coil 1 and the coil 2 generate magnetic fluxes which are in opposite directions. After the technical proposal is adopted, when the reactor works, the magnetic fluxes on all places are basically counteracted, no electromagnetic interference exists, an inductance value is not influenced by peripheric ferromagnetic substances. The utility model has the advantages of simple structure, simple manufacture, good volt-ampere characteristic and small noise when the utility model works.
Description
The utility model relates to a kind of reactor, mainly is the reactor that is used for electric power system.
Existing reactor generally has following two types: a kind of is the iron-core coil of band air gap, its objective is to utilize and contain the linearity that air gap improves voltage-current characteristic in the iron core, but noise is very big during the work of this kind reactor, and the linearity of voltage-current characteristic can not keep good in full voltage range; Another kind of reactor is ribbon core not, and coil is an integral body, but this kind reactor volume is big, during work surrounding environment is caused very big electromagnetic interference, and ferromagnetic substance on every side also seriously influences the inductance value of reactor.
The purpose of this utility model is the above-mentioned shortcoming that overcomes existing reactor, and a kind of no electromagnetic interference is provided, and inductance value is calculated the accuracy height, and the linearity of voltage-current characteristic keeps in full voltage range well, and simple in structure, volume is little, the little reactor of noise during work.
The utility model is by providing a kind of reactor with following structure to realize, this reactor comprises two groups of air core coils, two iron yokes made from ferromagnetic material, and folder.Coil groups the 1, the 2nd, series connection, every group can be made of one or more coils from parallel connection of coils or series connection, and the cross sectional shape of each coil is arbitrarily, and height can wait or not wait, around to can be identical or opposite.
The advantage of reactor of the present utility model is, the magnetic flux that coil is outside to remove upper and lower iron yoke is basic neutralisation all, has eliminated the electromagnetic interference to surrounding environment substantially.Improved the linearity of coil inductance again greatly, and simple in structure, simple for production.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, reactor of the present utility model comprises line group 1 and 2, iron yoke 3 and 4, folder 5.Described coil is with crossing lead to be wound in two air core coils, by scalding lacquer with its fixed in shape; Make upper and lower iron yoke 3,4 with two groups of ferromagnetic materials, the coil of having finalized the design is placed between the two iron yokes, and two groups of coil clamps are located between upper and lower iron yoke with folder 5; Fix with bolt 6, nut 7 at last.Coil 1 and coil 2 are connected, and its connected mode is for when alternating current passes through, and the flow direction that their produce is opposite.
When the coil midstream of reactor is crossed alternating current, because the flow direction that produces in two coils is opposite, make in the coil outside all basic neutralisations of all the local magnetic fluxs except that upper and lower iron yoke, thereby main flux can only pass through in the inside of two coils, be that magnetic circuit is that inside and upper and lower iron yoke by two coils forms the loop, the air gap that its path is a coil height by two length mainly constitutes, and the magnetic in two iron yokes is close very little, so the linearity of coil inductance is very good.Fix because of this length of magnetic path again, can not be diffused into other place, thereby to there not being electromagnetic interference on every side, winding inductance quantity is not subjected to the surrounding environment influence of (as there being ferromagnetic material on every side) yet.
Claims (2)
1. a reactor comprises coil, it is characterized in that:, with folder coil clamp is located between upper and lower iron yoke again as upper yoke (3), lower yoke (4) with two groups of ferromagnetic materials, and fixing with bolt (6) nut (7).
2. reactor according to claim 1 is characterized in that: connect in coil groups (1), (2), and the cross sectional shape of coil groups (1), (2) is can be arbitrarily, and height can wait or not wait, around to can be identical or opposite.
