Abstract
The invention relates to an environmental protecting and energy saving active field full magnetic screen squirrel-cage dry-type air reactor used in an electrical power system. Radial magnetic shielding board (9) is arranged on the two ends of the air reactor coil (14), and is composed of a plurality of sector magnetic shielding bodies; a corresponding magnetic screen wall (6) are uniformly arranged along the circle of the coil (14) at the radial periphery, the magnetic shielding board (9) and the magnetic shielding wall (6) together constitute a squirrel-cage full magnetic screen shell, and one point of which is effectively grounded. Thus, the electromagnetic leakage field and the electromagnetic leakage energy of the air reactor can be effectively restrained in the reactor, thereby fundamentally achieving the purpose of preventing the electromagnetic contamination, further more with the minimum additional loss, low noise and the squirrel-cage full magnetic screen shell itself does not generate local overheating.
Description
Affiliated field: the present invention 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 more than 100 amperes; 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.
Dry-type air-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.When 50 cycles, 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 electromagnetism that the coil electromagnetism field produced when reactor moved continuously leaks can be to spatial diffusion, especially the magnetic field at coil both ends is the strongest, magnetic flux is the most concentrated, the magnetic flux at coil both ends is to disperse and to restrain alternate to space radiation, propagation, living organism, air, instrument and equipment beyond the reactor are exerted an influence, people and environment are produced harm.
Produce serious electromagnetic pollution during the dry-type air-core reactor operation and the influence of environment is caused already the attention of people and some manufacturers, but can be controlled at reactor inside a kind of electromagnetic stray field, electromagnetism can be leaked of appropriate design, fundamentally prevent propagation, radiation that electromagnetic stray field, electromagnetism leak energy, the dry-type air-core reactor that reaches the purpose of control electromagnetic pollution is not seen any report of any publication and any information of public aspect so far.
Summary of the invention:
The objective of the invention is to provide a kind of environmental protection, energy-conservation active field all-magnetism shielding squirrel-cage shaped dry hollow reactor, 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 propagation, the radiation of energy, the control electromagnetic pollution, minimizing is to the harm of people and environment, and supplementary load loss are minimum, and itself can not produce local overheating the magnetic screen shell.
For achieving the above object, the present invention is positioned over the air core reactor coil body in the middle of the mouse cage shape all-magnetism shielding shell, both on the both ends of air core reactor coil and below the radial magnetic shield panel of making of grain oriented silicon steel sheet is set, radial magnetic shield panel is made up of the fan-shaped magnetic shield of several piece, the multistage cuboid that every fan-shaped magnetic shield is made by the grain-oriented silicon steel sheet that is cut into strip is bonded, but radial magnetic shield panel integrated bond or use the poured with epoxy resin moulding; Be uniformly distributed along the circumference towards periphery in air core reactor coil footpath fan-shaped magnetic shield outward flange straight line portion with radial magnetic shield panel is set, the position, the corresponding magnetic screen wall of making of grain oriented silicon steel sheet of quantity, the magnetic screen wall equates with the piece quantity of the fan-shaped magnetic shield of radial magnetic shield panel 〉=4, silicon steel sheet in the magnetic screen wall is cut into strip, place vertically, top and the following radial magnetic shield panel at air core reactor main coil both ends has constituted mouse cage shape all-magnetism shielding shell with corresponding magnetic screen wall around the coil, constitutes a complete closed magnetic loop; Only on the both ends of air core reactor coil and below the radial magnetic shield panel of making of silicon steel sheet is set, just constitute the magnetic screen dry-type air-core reactor; Only the magnetic screen wall evenly is set towards periphery, also just constitutes the magnetic screen dry-type air-core reactor in air core reactor coil footpath; Silicon steel sheet width separately in radial 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 propagation, the radiation 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 make, 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, along grain oriented silicon steel sheet roll the smooth and easy circulation of direction, magnetic resistance is minimum, the all-magnetism shielding shell is selected for use than low magnetic density, supplementary load loss are minimum, and noise is little, and itself can not produce local overheating the all-magnetism shielding shell.
