Abstract
The invention discloses an active field full-magnetic-shielding squirrel-cage current-limiting reactor, which comprises a shell, a coil, an iron core column, an upper insulating plate, a lower insulating plate and a squirrel-cage full-magnetic-shielding shell, wherein the coil is sleeved on the iron core column; the iron core column is arranged in the shell; the shell is provided with two binding posts; the two ends of the coil are connected with the two binding posts respectively; the axial direction of the iron core column is set as a horizontal direction; the upper insulating plate and the lower insulating plate are arranged at the upper end and the lower end of the shell respectively; the squirrel-cage 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 squirrel-cage current-limiting reactor, electromagnetic waves are shielded in a squirrel-cage full-magnetic-shielding shell, so that living organisms, air, instrument, equipment and the environment outside the shielding shell are prevented from being damaged.
Description
Technical field
The present invention relates to a kind of reactor, relate in particular to the all-magnetism shielding squirrel-cage shaped current limiting reactor of a kind of active field.
Background technology
In March, 1997,25 State Bureau of Environmental Protection the 18th command issue < < electromagnetic radiation environment was protected (second) power frequency intense radiation system in management method > > annex: 1, voltage send transformer substation system more than 100KV; 2, electric current in 100 peaces the power frequency equipment 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 is no magnetic loop, a large amount of electromagnetic stray field that it produces, electromagnetic stray field with electromagnetic form to spatial, radiation.When 50 cycle, electromagnetic wave approximately 60 millimeters of depth of penetrations in copper aluminium, in dry soil, the about 5000m of the depth of penetration.The electromagnetic stray field that when reactor moves continuously, coil magnetic field produces spreads to 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 reactor are exerted an influence, people and environment are produced to harm.
