Abstract
The utility model discloses an initiative field whole magnetic shielding mouse cage-shaped current limiting reactor comprising a case body, a coil, an iron core pin, an upper insulating plate, a lower insulting plate, a lower insulting plate and a mouse cage-shaped whole magnetic shielding case. The coil is arranged on the iron core pin in a sleeved mode. The iron core pin is installed in the case body. Two binding posts are arranged on the case body. The two posting pins are respectively connected with the two ends of the coil. The axial direction of the iron core pin is served as a horizontal direction. The upper insulating plate and the lower insulating plate are respectively installed at the upper end and the lower end of the case body. The mouse cage-shaped whole magnetic shielding case is formed by a magnetic shield plate and a magnetic shield wall in a connection mode. The magnetic shield plate is arranged along the horizontal direction. The magnetic shield wall is arranged along the vertical direction. The initiative field whole magnetic shielding mouse cage-shaped dry-type semi iron core reactor shields electromagnetic wave within the mouse cage-shaped whole magnetic shielding case. Therefore, damages to living organisms, air, apparatus, and environment which are outside the shielding case are not produced.
Description
Technical field
The utility model relates to a kind of reactor, relates in particular to the all-magnetism shielding squirrel-cage shaped current limiting 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.
