Abstract
The invention discloses an aluminum foil type electric reactor in the technical field of electric reactors, which comprises an upper iron yoke and a lower yoke, wherein at least one group of winding units are arranged between the upper iron yoke and the lower yoke; each group of winding units comprises a core column, two pulling plates and a hollow winding; the core column is arranged at the hollow part of the winding and positioned between the iron yoke and the lower yoke; the two pulling plates of each group of winding units are respectively arranged at both sides of the core column; the upper iron yoke and the lower yoke are respectively arranged between both ends of the two pulling plates; through holes are correspondingly arranged in both ends of the two pulling plates, the upper ironyoke and the lower yoke, a through bolt is arranged in the through holes, and the pulling plates are connected with the upper iron yoke and the lower yoke by a nut; a galloon is wound outside the twopulling plates, and the winding is directly wound outside the galloon. The structure leads the winding and the core column to be provided with a smallest clearance, reduces the magnetic leakage and can reduce the loss of the electric reactor; the production efficiency and the assembly precision are favorable; and the aluminum foil type electric reactor can be used for a low-frequency circuit to inhibit current change or lead the alternating current to shift a phase.
Description
Technical field
The present invention relates to a kind of electric component, particularly a kind of reactor.
Background technology
In the prior art, a kind of aluminum foil type electric reactor is arranged, its structure includes upper yoke and lower yoke, be provided with at least one group of winding element between upper yoke and the lower yoke, every group of winding element comprises stem stem, arm-tie, the winding of hollow and winding support, stem stem is arranged in the hollow space of winding, and between upper yoke and lower yoke, the arm-tie of every group of unit winding has two and be separately positioned on the stem stem both sides, winding then installs around outside winding support, winding support is sleeved on outside the arm-tie, upper yoke and lower yoke are separately positioned between the two ends of two arm-ties, the two ends of two arm-ties, upper yoke, correspondence is provided with through hole on the lower yoke, be provided with through bolt in the through hole and by nut with arm-tie and upper yoke, lower yoke, stem stem is connected and is fastening.This device needs to install around earlier winding during fabrication outside winding support, winding repeatedly is entwined after superimposed by aluminium foil and dielectric film sheet material; Then, winding and upper yoke, lower yoke, stem stem, arm-tie can be carried out connection, carry out dipping lacquer after the installation and handle, form product.Its weak point is: said structure feature and production method are to be mutually related, and need to use winding support during fabrication, otherwise, can't install around winding, therefore, winding support is a requisite structure in the prior art; This structure has not only caused the waste of material, for stem stem and arm-tie are installed smoothly, must leave bigger gap between winding support and the arm-tie, makes that the reactor loss is big, is unfavorable for itself heat radiation.
Summary of the invention
The purpose of this invention is to provide a kind of aluminum foil type electric reactor, make it easily manufactured, save material, simultaneously, the loss of reactor is little.
The object of the present invention is achieved like this: aluminum foil type electric reactor, comprise upper yoke and lower yoke, be provided with at least one group of winding element between upper yoke and the lower yoke, every group of winding element comprises stem stem, the winding of arm-tie and hollow, stem stem is arranged in the hollow space of winding, and between upper yoke and lower yoke, the arm-tie of every group of unit winding has two and be separately positioned on the stem stem both sides, upper yoke and lower yoke are separately positioned between the two ends of two arm-ties, the two ends of two arm-ties, upper yoke, correspondence is provided with through hole on the lower yoke, be provided with through bolt in the through hole and by nut with arm-tie and upper yoke, lower yoke is connected; Described two arm-ties are around with cotton yarn tape, and winding directly installs around outside cotton yarn tape.
Structure of the present invention is that the change by its manufacture method is achieved, and during fabrication, at first stem stem is clamped between two arm-ties, outside arm-tie,, carry out dipping lacquer then and handle, after the curing around cotton yarn tape, arm-tie, stem stem and cotton yarn tape are fixed to one, have bonding strength preferably; Coiling winding outside cotton yarn tape after coiling is finished, is installed upper yoke and lower yoke again, then, carries out dipping lacquer again and handles.From said process as can be seen, structure of the present invention can reduce leakage field so that have minimum gap between winding and the stem stem, can reduce the loss of reactor; Simultaneously, owing to omitted winding support, reduced cost; This structure can be enhanced productivity, and improves assembly precision; The present invention can be used in the low-frequency channel, to suppress the electric current variation or to make the alternating current phase shift.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
Wherein, 1 upper yoke, 2 arm-ties, 3 windings, 4 stem stems, 5 cotton yarn tapes, 6 lower yokes, 7 through bolts.
Embodiment
As Fig. 1 and 2, be aluminum foil type electric reactor, comprise upper yoke 1 and lower yoke 6, be provided with at least one group of winding element between upper yoke 1 and the lower yoke 6, every group of winding element comprises the winding 3 of stem stem 4, arm-tie 2 and hollow, stem stem 4 is arranged in the hollow space of winding 3, and between upper yoke 1 and lower yoke 6, upper yoke 1, lower yoke 6 and stem stem 4 are formed by stacking by the metal material of number of plate-shaped; Arm-tie 2 is made by low-permeability material, the arm-tie 2 of every group of unit winding 3 has two and be separately positioned on stem stem 4 both sides, upper yoke 1 and lower yoke 6 are separately positioned between the two ends of two arm-ties 2, correspondence is provided with through hole on the two ends of two arm-ties 2, upper yoke 1, the lower yoke 6, is provided with through bolt 7 in the through hole and by nut arm-tie 2 is connected with upper yoke 1, lower yoke 6; Described two arm-ties 2 are around with cotton yarn tape 5, and winding 3 directly installs around outside cotton yarn tape 5.
During fabrication, at first stem stem 4 is clamped between two arm-ties 2, around cotton yarn tape 5, carries out dipping lacquer then and handle outside arm-tie 2, after the curing, arm-tie 2, stem stem 4 and cotton yarn tape 5 are fixed to one, have bonding strength preferably; Coiling winding 3 outside cotton yarn tape 5 after coiling is finished, is installed upper yoke 1 and lower yoke 6 again, then, carries out dipping lacquer again and handles.
