Abstract
The invention relates to a multi-magnetic gap filter reactor used for direct-current pulse power supply filtering of an intermediate frequency power supply, which comprises a reactor; the reactor consists of an upper iron core, a lower iron core, and a plurality of sections of multi-magnetic gap multi-coil reactor uprights arranged between the upper iron core and the lower iron core; and each section of iron core in the plurality of sections of multi-magnetic gap multi-coil reactor uprights is sheathed by a coil packet. The multi-magnetic gap filter reactor has the advantages of small size, hard heating and hard magnetic saturation, small coil size, high inductance, large current-carrying capacity and good insulating strength as well as simple manufacture technique and low cost.
Description
Technical field
The present invention relates to a kind of a kind of many magnetic gaps filter reactor that is used for intermediate frequency power supply, belong to reactor and make the field.
Background technology
CN2508360Y, title " iron core filter reactor ", it is made up of iron core and coil.Iron core is by upper and lower iron core and place the iron core column between upper and lower iron core to form.The coil cover is characterized in that the iron core column adopts the folded system of segmentation layer by layer on the iron core column, isolate with insulating material between every section, makes the bed course air gap and the core section of iron core obtain best fit, and the linearity of iron core is risen, and loss is reduced greatly; Coil adopts the copper strips coiling, makes the kelvin effect of conductor reduce greatly, and turn-to-turn and interlayer distributed capacitance reduce greatly, thereby the equivalent AC resistance of reactor is descended, and has improved the quality factor of reactor.Its weak point: this iron core filter reactor is mainly used in the inhibition mains by harmonics, is not suitable for the dc pulse filtering of intermediate frequency power supply.
Existing intermediate frequency power supply DC filtering circuit, bear by traditional reactor always, on structural design, the iron core that builds up by stripe shape and U type silicon steel sheet always, be used for magnetic conduction, two groups of coils of the both sides overcoat of U sections core are equipped with the size that backing plate is used to regulate air gap between vertical bar and U sections core end face, prevent magnetic saturation.Its weak point: volume is big, and coil is difficult to be arranged, is easy to magnetic saturation, is only applicable to the filtering of middle-size and small-size power supply.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of a kind of many magnetic gaps filter reactor that is used for the dc pulse filtering of intermediate frequency power supply.
Design: high-power intermediate frequency power supply, also claim variable frequency power supply, it is the corollary apparatus of induction heating melting, its function is the alternating current that the three-phase 50HZ alternating current of electrical network is converted into intermediate frequency by " rectification-filtering-inversion ", be added on the coil of induction furnace, utilize electromagnetic induction principle that metal is heated and melting, the filter circuit of the intermediate frequency power supply in its parallel line partly is to be finished by flat ripple (filtering) reactor, main effect is carried out flat ripple to the 300HZ dc pulse electric current of AC-DC, be added to inverter circuit then, for inverter circuit provides a constant current source.
The present invention on structural design, U sections core constitute by lower core and the multi-thread bag reactor of the many magnetic gaps of multistage column and the iron core of the multi-thread bag reactor of the many magnetic gaps of multistage column on overlapped coil respectively design, be major technique feature of the present invention.The purpose of doing like this is: because a reactor has a plurality of magnetic gaps and a plurality of coil bag and multistage iron core to combine, it can make full use of the electromagnetism principle of stacking, under the situation that does not increase reactor volume and iron core, reactor is operated under bigger electric current, the better filter state, basically eliminated magnetic saturation, solved background technology and wanted for a long time to solve, but the technical barrier that never solves.
Technical scheme: a kind of many magnetic gaps filter reactor, it comprises reactor, described reactor is made of upper and lower iron core and the multi-thread bag reactor of the many magnetic gaps of the multistage column that is positioned between upper and lower iron core, is with the coil bag on the every iron leg core in the multi-thread bag reactor of the many magnetic gaps of the multistage column.
The present invention compares with background technology, and the one, volume is little, be difficult for heating, be difficult to magnetic saturation; The 2nd, have that winding volume is little, inductance value is big, ampacity is big, dielectric strength good; The 3rd, manufacturing process is simple, cost is low.
