Description
Technical field
The energy-conservation reactor that this utility model relates to a kind of new energy field and electric power, field of power supplies is unshakable in one's determination, is specifically related to a kind of reactor non-crystaline amorphous metal performance core of safety valve in gas-fired instrument.
Background technology
The anti-device of large-current electric is unshakable in one's determination, generally uses big air gap iron-core open magnetic circuit unshakable in one's determination, and even non iron-core uses air core coil.This is because big electric current produces big ampere-turn value, iron core must have anti-saturation characteristic, in the case of area of core section is certain, it is necessary to introduces bigger air gap in iron core, and guarantee iron core is unsaturated.The anti-device of large-current electric of the prior art, the most is the magnetic circuit breakaway-element iron core using single big air gap.Due to the existence of big air gap, bigger leakage field sense can be produced at air gap, cause air gap position coil and section unshakable in one's determination seriously to generate heat, even burn.The biggest air gap also can produce bigger electromagnetic radiation at the gap of magnetic circuit, causes electromagnetic pollution, electrical equipment around is often produced bigger electromagnetic interference, will damage electrical equipment time serious.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome deficiency of the prior art, it is provided that the large-current electric anti-device amorphous core that a kind of three gap structures, energy-conserving and environment-protective and electromagnetic pollution are few.
Technical scheme: in order to solve above-mentioned technical problem, three air gap large-current electric described in the utility model anti-device amorphous core, it includes cuboid non-crystaline amorphous metal soft magnetism magnetic piece and lower cuboid non-crystaline amorphous metal soft magnetism magnetic piece, middle cuboid non-crystaline amorphous metal soft magnetism magnetic piece it is provided with between cuboid non-crystaline amorphous metal soft magnetism magnetic piece and lower cuboid non-crystaline amorphous metal soft magnetism magnetic piece two ends on described, often end is provided with two middle cuboid non-crystaline amorphous metal soft magnetism magnetic piece, air gap is all left between described middle cuboid non-crystaline amorphous metal soft magnetism magnetic piece and upper cuboid non-crystaline amorphous metal soft magnetism magnetic piece and lower cuboid non-crystaline amorphous metal soft magnetism magnetic piece, it is divided into air gap, middle air gap and lower air gap, the spacing of described air gap is between 8-10mm, they form three gap structures, described middle cuboid non-crystaline amorphous metal soft magnetism magnetic piece sets four altogether, they collectively constitute rectangular core.
Described rectangular core is formed by stacking by non-crystaline amorphous metal soft magnetic ribbon.
Described upper air gap, middle air gap are identical with the spacing of lower air gap.
Described upper cuboid non-crystaline amorphous metal soft magnetism magnetic piece, middle cuboid non-crystaline amorphous metal soft magnetism magnetic piece are identical with the vertical sectional shape of lower cuboid non-crystaline amorphous metal soft magnetism magnetic piece.
Four described middle cuboid non-crystaline amorphous metal soft magnetism magnetic piece sizes are identical.
Iron core heat treatment to be passed through goes de-stress, when being assembled into iron core so that it is have two or more air gap, and the distribution form of air gap is not intended to, and total spacing of multiple air gap is considered as being equivalent to the equivalent separation of single air gap.
Beneficial effect: this utility model is compared with prior art, its remarkable advantage is: this utility model uses rapid solidification amorphous soft magnetic ribbon to manufacture iron core, non-crystaline amorphous metal soft magnetic ribbon has the core loss lower than silicon steel material, has lower energy loss and lower temperature rise in using；Core construction uses three air gaps, and in distributed, effectively reduces leakage magnetic flux, makes reactor caloric value reduce, and saves the energy and protection electrical equipment is without damage；The iron core of electric reactor of three air gaps, compared with single bigger air gap, has lower electromagnetic radiation, can effectively reduce electromagnetic environmental pollution and the destruction to electrical equipment, it is also possible to reduces the temperature at air gap and raises, and reduces the temperature rise of coil.
