Description
Affiliated field: the utility model relates to a kind of electric power system reactor.
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 the power transformation 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.
Oil immersion half iron core reactor is a power frequency intense radiation equipment, is power frequency alternating electromagnetism field source, because of there not being magnetic loop, and a large amount of electromagnetic stray field that it produced, electromagnetism leaks can be with form of electromagnetic wave to spatial transmission, radiation.A large amount of leakage fluxs penetrated hardwares such as metal fuel tank when reactor moved continuously, produce bigger eddy current loss, cause hardware local pyrexias such as fuel tank, the part leakage flux is leaked in air, living organism, air, instrument and equipment beyond the reactor are exerted an influence, people and environment are produced harm.
The iron core stem stem is set in air core coil whole reactor volume is dwindled significantly, its magnetic field also strengthens greatly; The harm that its stray field produces is also much serious when hollow.
The serious electromagnetic pollution that produces during the operation of half iron core reactor causes the attention of people and manufacturer already to the influence of environment; But can be controlled at reactor inside a kind of can the leakage electromagnetic stray field electromagnetism of appropriate design, prevent that fundamentally oil immersion half iron core reactor of the purpose that leaking of electromagnetic stray field electromagnetism leakage energy reaches the control electromagnetic pollution from not seeing any report of publication and any information of public aspect so far.
Summary of the invention: the purpose of this utility model is that a kind of environmental protection, energy-conservation all-magnetism shielding squirrel-cage shaped oil immersion half iron core reactor of active field will be provided, it can leak the electromagnetic stray field electromagnetism effectively can be controlled at reactor inside, prevent that fundamentally the electromagnetic stray field electromagnetism from leaking leaking of energy, the control electromagnetic pollution, minimizing is to the harm of people and environment, and supplementary load loss are minimum, and hardwares such as fuel tank can not produce local overheating, and itself can not produce local overheating the magnetic screen shell yet.
For achieving the above object, the utility model is that half iron core reactor body is positioned in the middle of the mouse cage shape all-magnetism shielding shell, promptly on the both ends of half iron core reactor body and below the radial octagon magnetic shield panel of manufacturing with grain oriented silicon steel sheet is set, radial octagon magnetic shield panel is made up of 8 fan-shaped magnetic shields, the multistage cuboid that every fan-shaped magnetic shield is manufactured by the grain-oriented silicon steel sheet that is cut into strip is bonded, but radial octagon magnetic shield panel integrated bond or use the poured with epoxy resin moulding; Be uniformly distributed along the circumference towards periphery in half iron core reactor coil footpath fan-shaped magnetic shield outward flange straight line portion with radial octagon magnetic shield panel is set, the position, corresponding 8 the magnetic screen walls of manufacturing with grain oriented silicon steel sheet of quantity, silicon steel sheet in [magnetic screen wall equate with the piece quantity of the fan-shaped magnetic shield of radial octagon magnetic shield panel 〉=4] magnetic screen wall is cut into strip, place vertically, the plane of silicon steel sheet has constituted mouse cage shape all-magnetism shielding shell perpendicular to the top and following radial magnetic shield panel at the half iron core reactor body both ends, plane [fuel tank also can be done squarely or cylindrical shape] of the suitable shape fuel tank of octagon with corresponding magnetic screen wall around the coil, constitute a complete closed magnetic loop, silicon steel sheet width separately in radial octagon magnetic shield panel and the magnetic screen wall becomes their thickness separately at this moment, their thickness equates also can be unequal, several very thin silicon steel sheets stack along thickness direction and become their width separately together, the edge of all silicon steel sheets is all towards stray field, the coil leakage flux circulates along the direction that rolls of grain oriented silicon steel sheet along the edge of silicon steel sheet, and magnetic resistance is minimum.Under 50 cycle power frequencies, the silicon steel sheet internal ratio that electromagnetic wave is very high at magnetic permeability, magnetic resistance is minimum decays many soon in copper aluminium, just stops fully in several millimeters.Be provided with the good ground strip of conduction in the silicon steel sheet of every fan-shaped magnetic shield and every magnetic screen wall, after all ground strips are interconnected together, some effective groundings, so just effectively the electromagnetic stray field electromagnetism is leaked and to be controlled at reactor inside, prevent that fundamentally the electromagnetic stray field electromagnetism from leaking leaking of energy, reach the purpose of control electromagnetic pollution, it is not exerted an influence to living organism, air, instrument and equipment beyond the reactor, alleviate harm people and environment.
Because mouse cage shape all-magnetism shielding shell adopts grain oriented silicon steel sheet to manufacture, the edge of silicon steel sheet is towards stray field, the direction that rolls of grain oriented silicon steel sheet is arranged to consistent with the reactor leakage field circulation direction that detours, the coil leakage flux is along the edge of silicon steel sheet, roll the smooth and easy circulation of direction along grain oriented silicon steel sheet, magnetic resistance is minimum, the all-magnetism shielding shell is selected for use than low magnetic density, supplementary load loss are minimum, noise is little, itself can not produce local overheating the all-magnetism shielding shell, and leakage flux effectively enters in the mouse cage shape all-magnetism shielding shell because of the path of attempt by the magnetic resistance minimum, and can not enter hardware such as fuel tank and produce supplementary load loss and cause hardware local overheatings such as fuel tank.
