Abstract
The invention discloses an air reactor with a shielding case. The periphery of the air reactor (1) is provided with the shielding case (2) made of conducting materials. The shielding case (2) is formed by connecting a plurality of rectangular conductors and a plurality of annular conductors. Through the shielding case arranged on the periphery of the air reactor, the strength value of a magnetic field around the air reactor can be reduced, and the reactor can not affect other devices in operation. In addition, distribution of space magnetic fields of an air reactor and the air reactor with the shielding case is measured respectively, after the shielding case is arranged, the magnetic field of a specific area of the space can be reduced, meanwhile, characteristics of the reactor can not be greatly influenced, linearity of inductance values is guaranteed, and the application range of the air reactor is enlarged.
Description
Technical field
The invention belongs in power reactor field, relate in particular to the electric device that uses large-scale power reactor.
Background technology
Reactor is divided into air core reactor, half iron core reactor and iron core reactor, although both space magnetic fields are comparatively concentrated because the effect of iron core distributes afterwards, due to iron core, to exist saturated phenomenon to cause inductance value to present non-linear, and application is restricted.Because magnetic conductive media is air, there is not saturated phenomenon in air core reactor, can ensure the linearity of inductance value, but space magnetic field distributes, disperses, and can have impact to surrounding devices.Reactor can arrange certain antimagnetic scope in the process of installing, and can not have conductor and other easy device affected by magnetic fields in antimagnetic scope.But the space that is difficult in reality provide enough large meets antimagnetic needs, stronger magnetic field can exert an influence to the staff in wherein simultaneously.
Summary of the invention
For mentioning air core reactor in above-mentioned background technology, when moving, in space, produce compared with the problem of high-intensity magnetic field around, the present invention proposes the air core reactor with radome, the present invention can guarantee to reduce the magnetic field of air core reactor operation time space specific region, reduces the needed antimagnetic scope of air core reactor operation.
Technical scheme of the present invention is: the air core reactor with radome of the present invention, the periphery of air core reactor arranges the radome that electric conducting material is made.
The periphery of above-mentioned air core reactor arranges the radome that metal material is made.
Above-mentioned radome is formed by connecting by some rectangle conductors and some circular annular conductors.
Above-mentioned radome is formed by connecting by two segment length's square conductor AF sections and CD section and two sections of circular annular conductors ABC sections and DEF section.
The cross section of above-mentioned radome includes some conductor layers and some bonding conductor layers, between adjacent conductive layers, by bonding conductor layer, is connected to integral body, and keeps electrical connection between conductor layer and bonding conductor layer.
The cross section of above-mentioned radome includes 10 layers of conductor layer and 9 layers of bonding conductor layer, between adjacent conductive layers, by bonding conductor layer, is connected to integral body, and keeps electrical connection between conductor layer and bonding conductor layer.
The present invention arranges the radome that metal material is made in the periphery of air core reactor, not only guarantee in structure it is one, and keep good electrical connection between each layer of conductor of radome.Under the effect of alternating magnetic field, in radome, can induction produce eddy current, eddy current produces reciprocal magnetic field, offsets a part of magnetic field that reactor produces.Bonding conductor between each layer of conductor want to guarantee be connected conductor between structural integrality.The present invention can guarantee to reduce the magnetic field of air core reactor operation time space specific region, reduces the needed antimagnetic scope of air core reactor operation.
