Abstract
The invention discloses an omni-directional magnetic shielding direct current filter reactor, which adopts a hollow structure and comprises a magnetic shielding box, a coil and a middle insulating support. The coil and the middle insulating support are both arranged in the magnetic shielding box, and the coil is arranged between the middle insulating support and a lateral plate of the magnetic shielding box. The middle insulating support is cylindrical, and an upper insulating plate and a lower insulating plate are circular. The two opposite sides of the magnetic shielding box are open. The omni-directional magnetic shielding direct current filter reactor has the advantages of being small in volume and small in flux leakage.
Description
Technical field
The present invention relates to a kind of omnidirectional magnetic screen DC filtering reactor.
Background technology
The DC filtering reactor is a kind of widely used electric product, mainly is divided into two kinds of versions of core-type reactor and open-core type reactor at present, and the reactor major advantage of core structure is that loss is little, Electro Magnetic Compatibility is better, volume is little.Its shortcoming is to have than big noise, in electric current increase non-constant of the inductance value linearity and anti-saturation ability.The structure of air core reactor is as shown in Figure 1, and its major advantage is that the inductance value linearity is good, to have very strong anti-saturation ability and a noise little, and shortcoming is that loss is big, volume is big, leakage field is big.
Summary of the invention
Technical problem to be solved by this invention provides a kind of omnidirectional magnetic screen DC filtering reactor, and this omnidirectional's magnetic screen DC filtering reactor has the little and little advantage of leakage field of volume.
The technical solution of invention is following:
A kind of omnidirectional magnetic screen DC filtering reactor adopts the open-core type structure, comprises that magnetic screen case, coil and intermediate insulation support, and coil and intermediate insulation support and all put in the magnetic screen case, and coil is arranged between the side plate of intermediate insulation support and magnetic screen case.
Be provided with upper insulation plate between the top board of coil and magnetic screen case, be provided with lower insulation plate between the base plate of coil and magnetic screen case.
Described intermediate insulation is supported for cylindrical shape, and described upper insulation plate and lower insulation plate are annular.
According to each described omnidirectional magnetic screen DC filtering reactor of claim 1-3, it is characterized in that the relative both-side opening of magnetic screen case.[very little according to leakage field direction magnetic screen case open side leakage field, need not to carry out magnetic screen, and design the time considers that this side is the heat radiation that opening helps reactor, institute's handlebar magnetic screen case is a hollow]
Described magnetic screen case adopts electrical pure iron to make.
Described magnetic screen case adopts electrical pure iron to make.
Upper insulation plate, lower insulation plate and intermediate insulation support and all adopt two stupid ether materials.
Upper insulation plate, lower insulation plate and intermediate insulation support and all adopt two stupid ether materials.
Beneficial effect:
Omnidirectional of the present invention magnetic screen DC filtering reactor, the coil of the open-core type in the middle of upper insulation plate, lower insulation plate, the intermediate insulation support fixation; Adopt the magnetic screen case that is connected to form both ends open by polylith electrical pure iron plate with bolt around the outside of coil.By described upper insulation plate and lower insulation plate hollow coil is clamped in the middle of the magnetic screen case securely.
Because the magnetic screen case made from electrical pure iron in hollow reactance coil outside carries out the magnetic conduction shielding action to the outside magnetic circuit of this air core coil; The self-induction of loop coefficient is increased; Thereby reach the effect that increases this reactor inductance amount; It is compared with the air core reactor of identical parameters can effectively reduce the number of turn of coil and the volume of coil, has reduced the consumption of winding wire material, most importantly simultaneously can reduce the space outerpace leakage field of this reactor and the load loss of coil greatly.It compares volume weight can slightly increase with core-type reactor, but the reactance curve will have bigger improvement, and electromagnetic noise can effectively reduce, space leakage field characteristic close.Through test, this reactor reactance amount under the operating current state of three times of rated current can reach more than 98% of specified inductance value, approaches the reactance curve of air core reactor fully, is that core-type reactor is beyond one's reach fully.This reactor space leakage field satisfies subway fully with transformer reactance device relevant criterion (the interior leakage field intensity of 500mm scope is no more than 1mT around the reactor), need leave reactor 1500mm-2000mm distance and will reach 1mT with capacity air core reactor space leakage field intensity.
