Abstract
The utility model provides an energy-saving dry half-core reactor. An iron core column is arranged outside a coil of an air core reactor, and the iron core column is as high as the coil; star-shaped frames are respectively arranged above and below the iron core column and the coil; a support insulator is arranged below the lower star-shaped frame; 1/3-1/2 part of the coil is surrounded by the iron core column in the circumference direction; and the iron core column is made of a high-magnetic electrical steel belt material which is integrally formed in a vacuum epoxy pouring manner. By utilizing the structure, a great amount of the iron core material is saved, and the magnetic conductivity in the coil is greatly increased; and the half-core reactor is dense and firm and has the advantages of small vibration in operation and low noise.
Description
Technical field
The utility model relates to a kind of energy-saving dry type half core reactor, belongs to the reactor field.
Background technology
In the prior art, the reactor with T-shaped core of traditional structure, its core material consumption is big, and cost is high.Complicated in mechanical structure.Especially a plurality of air gaps that on iron core column, distribute are prone to produce vibration and noise when being accompanied by huge electromagnetic force and causing moving.When the reactor capacity increased, the leakage flux of dispersing of air gap periphery tended to cause the serious overheated of local lamination and brings potential safety hazard.Because its iron core is exposed among the air, can not be used for the open air simultaneously, receive the restriction of environment for use.
For dry-type air-core reactor, because no iron core in the coil, magnetic flux is closed through air, and the permeability of air-core is low, magnetic resistance is big, and magnetic flux density is low, so small product size is big, the lead consumption is many, and loss is also just corresponding bigger.
The utility model content
To the weak point that above-mentioned prior art exists, the purpose of the utility model is to provide a kind of energy-saving dry type half core reactor.
The purpose of the utility model realizes through following technical proposals:
A kind of energy-saving dry type half core reactor; Iron core column is arranged on the coil outside of air-core reactor; And iron core column is identical with coil height, and the above and below of iron core column and coil is provided with starframe, and the starframe of below is arranged with supporting insulator; Iron core column is surrounded 1/3～1/2 of coil at circumferencial direction, and the iron core column material is the high magnetic conduction electrical steel strip material of overall vacuum epoxy casting moulding.
After adopting this structure, can not only practice thrift a large amount of core materials, magnetic permeability increases greatly in the coil, and half core reactor is closely knit firm, during operation the vibration little, noise is low.
Description of drawings
Fig. 1 is the dry type half core reactor profile that the utility model adopts.
Embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the execution mode of the utility model is not limited thereto.
Energy-saving dry type half core reactor; Iron core column 1 is arranged on coil 3 outsides of air-core reactor; And iron core column 1 is highly identical with coil 3, and the above and below of iron core column 1 and coil 3 is provided with starframe 2, and the starframe 2 of below is arranged with a plurality of supporting insulators 4; Iron core column 1 is surrounded 1/3～1/2 of coil 3 at circumferencial direction, and the iron core column material is the high magnetic conduction electrical steel strip material of overall vacuum epoxy casting moulding.
Owing in coil, put into the stem stem of being made by high magnetic conduction electrical steel strip material, magnetic permeability increases greatly in the coil thereby make.Therefore, compare with air-core reactor, under equal capacity, the diameter of coil can dwindle significantly, and the lead consumption significantly reduces, and loss has also reduced thereupon significantly.Compare with the dry-type air-core reactor with capacity, diameter has reduced 25%～35%, and electric energy loss has reduced about 25%～40% during operation.
Iron core column is through the moulding of overall vacuum epoxy casting, and is closely knit firm, during operation the vibration little, noise is low.The particular structural form has thoroughly solved in the stem stem of traditional iron core reactor owing to air gap is dispersed magnetic flux and is horizontally through the local overheating problem that lamination causes.Especially iron core column can directly be used for the open air after safeguard procedures are handled, and does not receive the restriction of any environmental condition.
Combine accompanying drawing that the utility model preferred implementation is specified above; But the utility model is not limited to above-mentioned execution mode; In the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from the utility model aim, make various variations.
