Abstract

The utility model relates to the field of transformers, in particular to a low-voltage coil of a dry type transformer. The low-voltage coil comprises a B-phase winding, wherein the B-phase winding is a layered cylinder formed by wires, the head end of the B-phase winding is connected with a first leading-out end, the tail end of the B-phase winding is connected with a second leading-out end, the included angle of the first leading-out end and the second leading-out end is 120 degrees, and the second leading-out end is located on one side, not reaching the first leading-out end in a winding mode, in the winding direction of the wires. The low-voltage coil has the advantages that the winding distance of the low-voltage winding is reduced, resistance of the low-voltage winding is lowered, when the low-voltage winding is assembled with a high-voltage winding and a medium-voltage winding, the resistance is more balanced, the partial heating phenomenon of the winding is avoided, materials of the low-voltage winding are greatly reduced, and the structure arrangement is more reasonable.

Description

A kind of low-voltage coil of dry-type transformer
Technical field
The utility model relates to field transformer, refers to especially a kind of low-voltage coil of dry-type transformer.
Background technology
It is cooling that dry-type transformer relies on cross-ventilation to carry out, and is generally used for localized lighting, electronic circuit.Existing stereo-triangular wound core dry-type transformer applies to appliance field widely, existing stereo-triangular wound core dry-type transformer comprises the A phase winding, B phase winding and C phase winding, and three windings all have wire to turn to cylindrical shape, and be provided with two exits on three windings, and two exits on each winding are positioned on same diameter, two exits and be positioned at the same side in the center of circle, because the resistance of B phase winding equates with the resistance of A phase winding and C phase winding, when the A phase winding, when B phase winding and C phase winding fit together, in use can cause the problems such as resistance unbalance, cause winding the local pyrexia phenomenon to occur, in sum, the material of the low pressure winding of this structure is too wasted, topology layout is unreasonable.
The utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of saving resource and structure to can not help the low-voltage coil of rational dry-type transformer.
The technical solution of the utility model is achieved in that a kind of low-voltage coil of dry-type transformer, comprise the B phase winding, this B phase winding turns to the stratiform cylinder by wire, the head end of described B phase winding is connected with the first exit, the end of B phase winding is connected with the second exit, described the second exit and the first exit form 120 degree angles, and this second exit is positioned at coiling direction along wire also not around the side to the first exit.
By adopting technique scheme, reduced the coiling distance of low pressure winding, reduced the resistance of low pressure winding, when this low pressure winding and high pressure winding and middle pressure winding fit together, resistance is balance more, solved the phenomenon that local pyrexia appears in winding, greatly reduced the material of low pressure winding, topology layout is more reasonable.
The utility model further is set to: on the side face between described conductor layer, be provided with gas channel supporting bar.
Be preferably, the width that the cross sectional shape of described gas channel supporting bar is waist is less than the width at two ends.
By adopting technique scheme, greatly increased the cooling effect of low pressure winding, and the gas channel supporting bar intensity of this structure is stronger, topology layout is reasonable.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model embodiment structural representation;
Fig. 2 is gas channel supporting bar structural representation in the utility model embodiment.
