Abstract

The utility model relates to an internal tightening screw iron core reactor. The upper and lower part of an iron core column are provided with pressing platforms or pressure plates. The pressing platforms or the pressure plates are provided with through holes. A pull rod is arranged between the through holes of the upper and lower pressing platforms or pressure plates. The pull rod is positioned inside a coil and is abutted against an iron core. The top and the bottom of the pull rod are fastened by nuts. An internal tightening screw tightening structure can select the number of pairs of the pressing platforms and internal tightening screws and the size of the tightening screws according to relative parameters of the reactor so as to generate a balanced and stable pressing force for the iron core column to effectively inhibit the vibration of the iron core and greatly reduce the noise of the reactor. Moreover, the internal tightening screw tightening structure completely changes the iron core structure of the conventional reactor, not only reduces the volume of the reactor, but also simplifies the production processes of the iron core of the reactor and reduces the production cost.

Description

In draw the screw iron core reactor

Technical field

The utility model relates to a kind of power equipment in the electrical network, is a kind of iron core reactor specifically.

Background technology

Along with developing rapidly of conservation-minded society's construction, energy-conservation, material-saving and environmental protection become the restriction bottleneck of common iron core reactor production development gradually.

Existing common iron core reactor is because iron core column and iron core cake adopt is that the punching bar cramp is tight, and the lamination of stem stem needs punching, complex process not only, and, increased core loss because the existence of punching makes the local magnetic of iron core close bigger than normal; The punching bar takies insulation distance, causes product cost to increase; The outside draws the structure of screw rod tension to make the tension between iron core column and the iron core cake stressed undesirable, can not contain core vibration well, so the iron core reactor noise ratio of ordinary construction is bigger.

Summary of the invention

The purpose of this utility model is exactly the defective that exists at existing common reactor, and a kind of reduction core loss is provided, and reduces noise significantly, have material-saving, energy-conservation and environmental protection in draw the screw iron core reactor.

For finishing the technical scheme that the foregoing invention purpose taked be: draw the screw iron core reactor in a kind of, it is characterized in that: be equipped with up and down in iron core column and present a theatrical performance as the last item on a programme or pressing plate, present a theatrical performance as the last item on a programme or pressing plate on be shaped on open-work, between last bottom platen or pressing plate open-work, pull bar is housed, pull bar is positioned at coil inside, near iron core, use nut fastening up and down.

The beneficial effects of the utility model:

1, simplifies the iron core procedure, improve the silicon steel sheet utilance;

2, cancelled the punching of iron core column, iron core cake, avoided because the local flux density of iron core becomes the big loss that produces;

3, draw screw tension structure in since the stainless steel pull bar near iron core, iron core is stressed evenly constant during the pull bar tension, can contain core vibration effectively, reaches the purpose that reduces the iron core reactor noise significantly;

4, owing to draw screw tension structure in adopting, tangible pull bar be can't see in iron core reactor product outside, and it is simply compact to have overall structure, the characteristics of good looking appearance.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a cutaway view of the present utility model.

Fig. 3 is an end view of the present utility model.

Embodiment

Accompanying drawings structure of the present utility model.

Draw the screw iron core reactor in a kind of, as shown in Figure 1 and Figure 2.Each iron core column 3 is to be made of iron core column and iron core cake, iron core column and the not punching of iron core cake, adopt gluing between sheet, band press dry dry, and the polyester belt technology for binding makes iron core fastening, and a upper holder 1 is equipped with on iron core top, or pressing plate, a bottom platen 5 or pressing plate or device body footing are equipped with in the bottom, are shaped on open-work on upper holder 1 and bottom platen 5, and the tension structure that a pair of stainless steel pull bar 2 constitutes single iron core column is housed between upper holder 1 or bottom platen 5 open-works.According to the calculating of the relevant parameter of reactor select to present a theatrical performance as the last item on a programme, in draw the screw rod logarithm and draw the screw rod size, can adopt and draw screw rod in two or three pairs of.

Stainless steel pull bar 2 near iron core, uses double nut fastening up and down between coil 4 and iron core column 3, pull bar and iron core column can adopt fastening (resin-cast or colligation) or not fastening form.

In draw screw tension structure to cancel common iron core reactor iron core column, iron core cake punching technology and punching bar cramp locking structure, iron core column, iron core cake are adopted gluing between sheet, band press dry dry, the polyester belt technology for binding, not only simplified the iron core procedure, and it is remarkable to clamp effect, and it is too concentrated to have changed punching bar clamping force, the unfavorable defective of clamping force.

In draw stainless steel pull bar in the screw tension structure between coil and iron core, near iron core column, so be called " in draw screw ".

In draw screw tension structure since the stainless steel pull bar near iron core, iron core is stressed evenly constant during the pull bar tension, can contain core vibration effectively, reaches the purpose that reduces the iron core reactor noise significantly.

Claims

1. draw the screw iron core reactor in one kind, it is characterized in that: be equipped with up and down in iron core column and present a theatrical performance as the last item on a programme or pressing plate, present a theatrical performance as the last item on a programme or pressing plate on be shaped on open-work, between last bottom platen or pressing plate open-work, pull bar is housed, pull bar is positioned at coil inside, near iron core, uses nut fastening up and down.
