Abstract
The utility model discloses a kind of epoxy pouring type dry-type transformer iron core, the iron core includes stem, iron yoke, the stem is Three-dimensional triangle structure, it is divided into stem and lower stem, it is connected respectively with the iron yoke, the longer than upper stem of lower stem, lower stem is fixed on fixture, it is caught in clip groove, groove inner wall is filled equipped with insulating part；Winding is sleeved on upper and lower stem.The utility model by the folded appendiron core transformer of tradition and closed type three-dimensional winding iron core carried out it is perfect merge, lower than traditional laminated core transformer loss, cost is advantageously.
Description
Technical field
It the utility model is related to transformer technology field, more particularly to a kind of epoxy pouring type dry-type transformer iron core.
Background technology
Iron core is magnetic circuit part main in transformer, and traditional transformer is all for laminated core or volume iron core of remaining silent, and is lacked
Point is complex process, need to be designed with special equipment and particular manufacturing craft, of high cost, efficiency is low.The common opening mode of existing market is
Bridging type, complex process.
Utility model content
For the deficiency of above-mentioned technology, the utility model aim is to provide a kind of epoxy pouring type dry-type transformer iron core,
Improvement is optimized to the structure of iron core winding on the basis of closed type three dimensional wound core, life can be processed using traditional equipment
Production, greatly improves utilization rate of equipment and installations and manufacture efficiency, especially pronounced applied to dry-type distribution transformer.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of epoxy pouring type dry type becomes
Depressor iron core, the iron core include stem, iron yoke, and the stem is Three-dimensional triangle structure, is divided into stem and lower stem, respectively
It is connected with the iron yoke, the longer than upper stem of lower stem, lower stem is fixed on fixture, is caught in clip groove, and groove inner wall is equipped with
Insulating part is filled；Winding is sleeved on upper and lower stem.
Further, the iron core winding series end classification is using equivalent height formula straggly.
Further, the winding is dry type high-voltage coil and low-voltage coil, and moulding by casting is carried out with casting mold.
The utility model by the folded appendiron core transformer of tradition and closed type three-dimensional winding iron core carried out it is perfect merge, than tradition
Laminated core transformer loss is lower, and cost is advantageously.On the basis of closed type three dimensional wound core to iron core winding structure into
Row optimization improvement, efficiency significantly improve, save manufacture mould and special equipment cost, particularly aobvious applied to dry-type distribution transformer
Write.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the I of the utility model to partial structural diagram.
In figure：1st, upper stem；2nd, lower stem；3rd, iron yoke
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
With reference to Fig. 1-2, a kind of epoxy pouring type dry-type transformer iron core, iron core includes stem, iron yoke, and stem is solid three
Corner structure, is divided into stem 1 and lower stem 2, is connected respectively with the iron yoke 3, the longer than upper stem 1 of lower stem 2, lower stem 2
It is fixed on fixture, is caught in clip groove, groove inner wall is filled equipped with insulating part.Winding dry type high-voltage coil and low-voltage coil is sleeved on lower stem
On 2, then stem 1 is plugged on stem 2.
Above-mentioned epoxy pouring type dry-type transformer iron core, technological process are as follows：
1. using particular manufacturing craft, stem is wrapped on mould, is operated by digital control system, make stem winding series end
The equivalent height formula straggly that uses is classified, higher level is first fixed with subordinate using glue in winding process, then coordinates spot welding to be fixedly connected,
Winding shaping；
It is sent into 2. the iron core after the completion of winding is placed on trolley in annealing road, carries out core annealing processing；
3. after the completion to be assembled of end splicing position, gluing is carried out using the epoxy resin for having insulation effect, gluing finishes
When air-dried 20-30 is small at normal temperatures afterwards.
