Abstract
The utility model discloses a reactor with dry-type iron core used to shielding field magnet positively. During continuous operation, old reactors with dry-type iron core leak electromagnetic field and electromagnetic energy transmit and radiate by means of electromagnetic wave so as to damage human body and environment. The utility model provides a wall of magnetic shielding higher than the coil all around coil of the reactor and this wall of magnetic shielding has the same length and width as that of the reactor. Effective grounding is arranged for the wall of magnetic shielding, thus effectively control the electromagnetic field and electromagnetic energy inside the reactor, which prevents pollutions caused by electromagnetism and does not influence living being, air, apparatus and device. Reducing hazards to human being and environment and with advantages of low supplementary load loss and low noise, the wall of magnetic shielding and other metal components do not heat up locally.
Description
Affiliated field:
The utility model relates to a kind of power 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.
Reactor with T-shaped core iron core and coil are not immersed in the iknsulating liquid, have do not fire, not quick-fried, advantages such as volume is little, few maintenance.Reactor with T-shaped core is a power frequency intense radiation equipment, be power frequency alternating electromagnetism field source, its electromagnetic stray field 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, the about 5000m of the depth of penetration in the soil of drying.The electromagnetism that the continuous operation coil stray field of reactor produces leaks and can living organism, air, instrument and equipment beyond the reactor be exerted an influence in the spatial transmission radiation, and people and environment are produced harm.
The even more serious electromagnetic pollution of the ratio dry-type power transformer that reactor with T-shaped core operation produces is to the influence of environment, and a kind of can the leakage electromagnetic stray field electromagnetism of appropriate design can be controlled at reactor inside, prevent that fundamentally the electromagnetic stray field electromagnetism from leaking propagation, the radiation of energy, reach the reactor with T-shaped core of the purpose of control electromagnetic pollution, do not see any report of any publication and any information of public aspect so far.
Summary of the invention:
