Abstract
The utility model discloses a transformer coil which comprises a lower voltage coil (1), a high voltage coil (2) and an insulating cylinder (4), wherein the high voltage coil (2) is sleeved outside the lower voltage coil (1); the insulating cylinder (4) is arranged on the inner side wall of the high voltage coil (2), a plurality of stays (3) axially distributed are arranged between the low voltage coil (1) and the insulating cylinder (4), each stay (3) is fixed on the outer wall of the low voltage coil (1), and a cavity (5) is arranged between every two adjacent stays (3). The transformer coil has the advantages of enabling the insulating cylinder to have good insulating effect and withstanding voltage and achieving reliability.
Description
Technical field
The utility model relates to the power transmission and transforming equipment technical field, specifically is a kind of transformer coil.
Background technology
Transformer coil generally comprises low-voltage coil and high-tension coil, and this high-tension coil is enclosed within outside the low-voltage coil, and transformer is in order to practice thrift cost; The main empty path distance that shortens must increase insulating cylinder between high-low pressure, improve the withstand voltage level of transformer; And insulating cylinder material toughness is relatively good, and insulating cylinder is directly to be placed between high-voltage coil and low-voltage coil usually, and is unfixing; Just can't be thereby be easy to fully as requested in the precalculated position, usually easily near high-tension coil or low-voltage coil.Cause the insulation effect of insulating cylinder not have the good of expection, make withstand voltage reliable inadequately.
The utility model content
The technical problem that the utility model will solve is to provide a kind of insulation effect of insulating cylinder that makes good, withstand voltage reliable transformer coil.
The technical scheme of the utility model is, a kind of transformer coil with following structure is provided, and comprises low-voltage coil, high-tension coil and insulating cylinder, and said high-tension coil is enclosed within outside the low-voltage coil; The madial wall of said high-tension coil also is provided with insulating cylinder, also is provided with the stay of some axial distribution between said low-voltage coil and the insulating cylinder, and every bracing bars is fixed on through adhesive layer on the outer wall of low-voltage coil, is provided with cavity between the adjacent stay.
Said adhesive layer is a double faced adhesive tape.
After adopting above structure; The utility model compared with prior art; Have the following advantages: owing to also be provided with the stay of some axial distribution between said low-voltage coil and the insulating cylinder, every bracing bars is fixed on through adhesive layer on the outer wall of low-voltage coil and makes insulating cylinder be fixed on preposition like this, avoids too near high-tension coil or low-voltage coil; Make the insulation effect of insulating cylinder good, withstand voltage reliable.Can also hang down and the slightly poor insulating cylinder of material by used thickness simultaneously, save insulating material, thereby reduce cost.
Description of drawings
Accompanying drawing is that the master of the transformer coil of the utility model looks sketch map.
As shown in the figure: 1, low-voltage coil, 2, high-tension coil, 3, stay, 4, insulating cylinder, 5, cavity.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
As shown in the figure, the transformer coil of the utility model comprises low-voltage coil 1, high-tension coil 2 and insulating cylinder 4, and said high-tension coil 2 is enclosed within outside the low-voltage coil 1; The madial wall of said high-tension coil 2 also is provided with insulating cylinder 4; Also be provided with the stay 3 of some axial distribution between said low-voltage coil 1 and the insulating cylinder 4; Every bracing bars 3 is fixed on the outer wall of low-voltage coil 1 through adhesive layer; Be provided with cavity between the adjacent stay 3, the cavity of just forming 5 by adjacent stay 3, low-voltage coil 1 and insulating cylinder 4 four.
Said adhesive layer is a double faced adhesive tape.
Claims (2)
1. a transformer coil comprises low-voltage coil (1), high-tension coil (2) and insulating cylinder (4), and said high-tension coil (2) is enclosed within outside the low-voltage coil (1); The madial wall of said high-tension coil (2) also is provided with insulating cylinder (4); It is characterized in that: the stay (3) that also is provided with some axial distribution between said low-voltage coil (1) and the insulating cylinder (4); Every bracing bars (3) is fixed on through adhesive layer on the outer wall of low-voltage coil (1), is provided with cavity (5) between the adjacent stay (3).
