Abstract

The utility model relates to an amorphous-alloy iron-core magnetically controlled reactor, which aims at solving the technical problems that in the prior art, the reactor has higher loss of iron core, complicated structure, higher cost and the like. The amorphous-alloy iron-core magnetically controlled reactor comprises an iron core and coils, and is characterized in that the iron core is annular and made of amorphous-alloy; and the left side and the right side of the iron core are respectively sheathed with a coil through which direct current and alternating current can pass simultaneously. By adopting the technical scheme, the amorphous-alloy iron core is adopted, the magnetic conductivity of the magnetically controlled reactor is higher, and the needed section is small, thus reducing the whole volume of the reactor, and greatly reducing the loss of the coils and the iron-core; and the loss of amorphous-alloy iron core is less than one third that of the common iron core made of cold-rolled oriented silicon steel sheet, the loss of the iron core is reduced by 60 percent, the total loss is reduced by 30 percent, and the energy-saving effect is good.

Description

The amorphous alloy iron core magnet controlled reactor
Technical field
The utility model relates to the reactor that electric power system is used, specifically a kind of amorphous alloy iron core magnet controlled reactor.
Background technology
Electric power system power transmission and distribution and commercial power all need a large amount of reactive powers, if these reactive powers are transported to the user from the power plant then can produce very big line loss, also make simultaneously electric power transmission network produce bigger voltage fluctuation, the reasonable plan that addresses these problems is in load side shunt capacitor local compensation reactive power to be installed, but the reactive power load fluctuates widely, and the reactive power of capacitor output is fixed, therefore need a kind of adjustable reactor, make the reactive power that produces with system after the reactive power addition of the reactive power of reactor dynamic adjustments and capacitor realize in-situ balancing.
Existing reactor regulation technology mainly is by core of reactor is carried out D.C. magnetic biasing, thereby changes the adjusting that the iron core magnetic permeability is realized inductance.Because the work magnetic flux density of iron core raises after the iron core D.C. magnetic biasing, the loss of iron core will be much higher than the loss of common transformer.Though the saturated new technology in part is incorporated into the application of magnet controlled reactor in recent years, thereby core loss is reduced greatly, its loss objective still fails to reach reasonable range, and silicon sheet core consumption is bigger, and loss is also bigger, and cost is higher.
Summary of the invention
The purpose of this utility model is that the core loss that prior art exists is big in order to solve, complex structure, the more high technical problem of cost, and a kind of loss that provides is little, cost is low, the tangible amorphous alloy iron core magnet controlled reactor of energy-saving effect.
In order to solve the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of amorphous alloy iron core magnet controlled reactor, it comprises iron core and coil, it is characterized in that: described iron core is annular amorphous alloy iron core, the iron core left and right sides is respectively installed with the coil that can flow through alternating current-direct current simultaneously.
In the further detailed structure of the utility model, also have following technical characterictic: the iron core in the described coil is provided with a plurality of air gaps that form by machine work.
Compare with original technology, the utlity model has following advantage and good effect:
Because the utility model has adopted technique scheme, adopted amorphous alloy iron core, its magnetic permeability is higher, required cross section is little, thereby the reactor overall volume is dwindled, and coil loss and core loss all reduce significantly, the loss of amorphous alloy iron core is below 1/3rd of common cold-rolled orientation silicon steel sheet iron core, it is about 60% that core loss reduces, and it is about 30% that total losses reduce, good energy-conserving effect.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to Fig. 1, Fig. 2, the utility model amorphous alloy iron core magnet controlled reactor comprises iron core 1 and coil 3, and described iron core 1 is annular amorphous alloy iron core, and iron core 1 left and right sides is respectively installed with the coil 3 that can flow through alternating current-direct current simultaneously.Iron core 1 in the described coil 3 is provided with a plurality of air gaps 2 that form by machine-tooled method, makes iron core 1 have only part, air gap 2 place saturated when the common excitation of ac and dc current, thereby has reduced iron core 1 loss.
Referring to Fig. 3, the utility model amorphous alloy iron core magnet controlled reactor is every to be made up of two groups of iron cores 1, be wound with two identical coils 3 on each iron core 1, these two coils 3 and two coils 3 on another iron core intersect respectively and compose in parallel the AC coil input again after connecting, and intersect series connection point as the DC excitation current input terminal, this mode of connection power of alterating and direct current does not disturb mutually, realizes the shared one group of coil of alternating current-direct current, provides cost savings.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection range of technical solutions of the utility model according to technical spirit of the present utility model.
