Abstract

The utility model discloses a cylinder pouring coil which comprises a wire (2), an inner wrapping insulator (1) and an outer wrapping insulator (3) and is characterized in that the wire (2) is arranged continuously in the axial direction. The pouring coil adopts the continuous coil to replace the existing subsection coil. Compared with the prior art, the cylinder pouring coil has the advantage that the coil is close in axial winding without inter-section plugging blocks, improves axial resin filling rate, is less in resin usage and favorable for reducing cost, adopts the continuous structure, avoids inter-section high field intensity and is favorable for reducing partial discharge.

Description

Cylinder cast-type coil
Technical field
The utility model relates to the transformer technology field, specifically is a kind of new construction cylinder cast-type coil of transformer.
Background technology
Mostly the cast-type loop construction of existing transformer is subsection cylindrical formula coil, comprises lead, the insulation of interior bag, outsourcing insulation, intersegmental chock.Earlier in bag insulation in said on the cylinder, more said lead is wrapped in the insulation in said during making, then with the intersegmental chock jam-pack of intersegmental usefulness, at last around said outsourcing insulation; Carry out resin-cast then, all spaces are filled up.
Shown in accompanying drawing 2, be a kind of four-part form cylindrical layer winding of prior art, there is following shortcoming in this kind subsection cylindrical formula coil:
1. owing to be segmented, i.e. lead 2 ' segmentation vertically, the intersegmental chock that is provided with; So coil axes is to dividing four sections; There are three intersegmental distances (10mm) promptly to have intersegmental space 4 ', cause coil axes many, be unfavorable for reducing cost to (also be Cylindorical rod to) resin loading.
2. unavoidably there is intersegmental high field intensity in coil axes to dividing four sections, and the control of (partial discharge) is put in the office of being unfavorable for.
The utility model content
The utility model provides a kind of saving material to the above-mentioned deficiency of prior art, intersegmental low field intensity, and the cylinder cast-type coil of control is put in the office of being beneficial to.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts does, a kind of cylinder cast-type coil comprises lead, the insulation of interior bag, and the outsourcing insulation is characterized in that: described lead (Cylindorical rod to) vertically is the continous way setting.
After adopting said structure, the coil of the utility model does not carry out the segmentation setting, therefore need not to be provided with intersegmental chock yet, compared with prior art, has the following advantages:
(1) coil axes is tight to coiling, does not need intersegmental chock, and it is few to resin filling rate, resin demand to have improved coil axes, is beneficial to reduce cost.
(2) coil adopts the continous way structure, has avoided intersegmental high field intensity, helps reducing office and puts.
Description of drawings
Fig. 1 the utility model drum type brake cast-type coil is along cylinder axial section structural representation.
Shown in the figure, 1, interior bag insulation 2, lead 3, outsourcing insulation.
Fig. 2 prior art subsection cylindrical formula coil.
2 ', lead, 4 ', intersegmental space.
Embodiment
Below in conjunction with accompanying drawing the utility model transformer teeming continuous winding is described further.
As shown in Figure 1; The transformer teeming continuous winding of the utility model; Bag insulation 1 in comprising, lead 2 and outsourcing insulation 3; It is characterized in that: described lead 2 vertically for the continous way setting (described like accompanying drawing 1 axially is illustrated vertical, just cylinder axially) be lead not segmentation vertically, intersegmental space be not set.When making: bag in described is insulated 1 elder generation on cylinder, more said lead 2 is wrapped in the insulation 1 in said, insulate 3 in lead 2 outsides around said outsourcing at last; The as can beappreciated from fig. 1 lead of every group of coil (diagram vertical) not segmentation vertically, all are continuous settings, also do not use intersegmental chock.
Adopt above-mentioned continuous winding to substitute existing graded winding, compared with prior art, have the following advantages: coil axes is tight to coiling, does not need intersegmental chock, and it is few to resin filling rate, resin demand to have improved coil axes, is beneficial to reduce cost; Coil adopts the continous way structure, has avoided intersegmental high field intensity, helps reducing office and puts.

Claims (1)

1. a cylinder cast-type coil comprises lead (2), interior bag insulation (1), and outsourcing insulation (3) is characterized in that: described lead (2) is the continous way setting vertically.
