The insulation column is arranged in a central through hole in the iron core, an annular hollow cavity surrounding the insulation column is arranged in the iron core, the inner working winding is arranged on the surface of the inner wall of the annular hollow cavity, the outer working winding is arranged on the surface of the outer wall of the annular hollow cavity, a gap is arranged between the inner working winding and the outer working winding, and the control winding is arranged on the outer surface of the circumference of the iron core. The axial direction of the insulation column is regarded as the up-down direction, and the mouse-cage-shaped full-magnetic-shielding shell is formed by connecting a horizontal magnetic shielding plate and a vertical magnetic shielding wall. According to the active-field full-magnetic-shielding mouse-cage-shaped adjustable iron core reactor, electromagnetic waves are shielded in the mouse-cage-shaped full-magnetic-shielding shell, and damage can not be caused to living organisms, air, instruments and equipment, and the environment outside the shielding shell.
Description
Technical field
The utility model relates to a kind of reactor, relates in particular to the all-magnetism shielding squirrel-cage shaped adjustable magnetic core reactor of a kind of active field.
Background technology
(second) power frequency intense radiation system in State Bureau of Environmental Protection's the 18th command issue on March 25th, 1997 " electromagnetic radiation environment protection management method " annex: 1, voltage send transformer substation system more than 100KV; 2, electric current is at the power frequency equipment of 100 peaces more than doubly; 3, light rail and main line electric railway.Advise that above-listed construction project should handle environmental protection and declare registration formalities before project verification, use above-listed electromagnetic radiation equipment before procuring equipment, to handle environmental protection and declare registration formalities.
Reactor is power frequency intense radiation equipment, is power frequency alternating electromagnetism field source, because there not being magnetic loop, a large amount of electromagnetic stray field that it produces, electromagnetic stray field with electromagnetic form to spatial, radiation.When 50 cycle, about 60 millimeters of electromagnetic wave depth of penetration in copper aluminium, in the soil of drying, the about 5000m of the depth of penetration.The electromagnetic stray field that coil magnetic field produced when reactor moved continuously spreads to the space, especially the magnetic field at coil both ends is the strongest, magnetic flux is the most concentrated, the magnetic flux at coil both ends alternately changes to space radiation, propagation with radiation and convergence, living organism, air, instrument and equipment beyond the reactor are exerted an influence, people and environment are produced harm.
