Description
Technical field
The utility model relates to be applied to three-phase reactor technical field, in particular to one in electrical or power electronic system
The three-phase reactor of the big heat dissipation area of kind.
Background technique
Three-phase reactor applied currently on the market generally use loop construction be with single or more insulated wire it is flat around
On skeleton, by the number of turns how much be coiled into two layers or two layers or more.Due between layers to need to climb when coiling, and
Interlayer can stress, be easy to cause insulating layer impaired, in turn result in coil short and burn, so interlayer needs to insulate, when climbing is needed
Reinforce insulating.It does so and there is following disadvantage:
1. operating efficiency is low: insulation just needs to shut down and spends working hour when doing interlayer and climbing in coiling.
2. insulating materials increased costs: doing to insulate and just need insulating materials, increase insulation and is increased by insulating materials cost.
3. coil dimension increases: insulating materials has certain thickness, and increasing insulating materials just centainly will increase coil thickness
Degree.
4. temperature increases weak heat-dissipating: since there are multilayers for coil, in addition insulating layer thermal coefficient is poor, temperature is from height from the inside to surface
It is deposited to low point, i.e., temperature is high on the inside of coil, and coil temperature outside is low, temperature difference 10-20 degree.
Utility model content
The technical problem to be solved by the utility model is to provide one for the problems of above-mentioned prior art
The three-phase reactor of the big heat dissipation area of kind, it is intended to reduce three-phase reactor material cost, improve product operating efficiency, reduce product
The inside and outside temperature difference is to improve the reliability of product.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of three-phase reactor of big heat dissipation area, including iron core and coil assembly, the iron core are described in stud
Iron core tool is gripped there are three stem and upper and lower iron, each stem and upper and lower iron grip between be provided with air gap；On three stems
It is provided with coil block, each coil block includes coil rack and the coil that is wound on coil rack, which is characterized in that
The coil is formed using the coiling of Flat wire vertical winding mode, and the coil is from being parallel in terms of the axis direction of stem by several upper circle lines
Circle and several lower circle interleaving coils are arranged, wherein front-rear direction or left and right directions of the interior chamber size of lower circle coil in interior chamber
Amplify a coil width size.
In a preferred embodiment of the utility model, the flat wire width-thickness ratio reaches 1:2~15.
Due to using technical solution as above, the more original scheme of the heat dissipation area of the coil of the utility model increases 1.5-
10 times.
By actual test, the utility model has the advantage that cost reduces under the same terms compared with prior art
20% or more, there is air-cooled lower temperature rise to reduce by 30% or more, operating efficiency improves 2 times or more.
