Abstract

The utility model relates to a transformer capable of preventing a coil from being broken down, which comprises a transformer frame, a pin, a primary coil and a secondary coil, wherein the primary coil and the secondary coil are formed by winding enameled copper wires; the primary coil is directly wound on the transformer frame; the outside of the primary coil is wrapped with an insulating tape; the secondary coil is wound on the insulating tape wrapped outside the primary coil; the two sides of each of the primary coil and the secondary coil are wrapped with insulating tapes respectively. The transformer capable of preventing the coil from being broken down overcomes the defects that the conventional transformer coil, is directly wound on the transformer frame, has a small physical distance between the primary coil and the secondary coil, and is easy to leak electricity and easy to break down in high voltage.

Description

A kind of transformer that prevents that coil from puncturing

Technical field

The utility model relates to transformer technology field, particularly relates to the transformer that a kind of high pressure resistant, anti-coil punctures.

Background technology

Traditional transformer, it is directly wound on primary coil on transformer framework, and encloses after insulating tape in primary coil outer wrapping one, directly at the outside of insulating tape coiling secondary coil.The transformer of this structure, because of the spacing between primary coil and secondary coil shorter, in actual use, between primary coil and secondary coil, usually there is leaky, under high-pressure situations, easily between primary coil and secondary coil, puncture, even damage coupled relevant electrical equipment thereby damage transformer.

Utility model content

The technical problems to be solved in the utility model be to provide a kind of high pressure resistant, can effectively prevent between coil electric leakage and the transformer puncturing.

The utility model is achieved through the following technical solutions:

A kind of transformer that prevents that coil from puncturing, comprise transformer framework, stitch, primary coil, secondary coil, primary coil and secondary coil are to form with enamel covered wire coiling, primary coil is directly wound on transformer framework, cover at primary coil external application insulating tape parcel, secondary coil is wound on the insulating tape of primary coil outer wrapping, it is characterized in that: the both sides at primary coil and secondary coil are surrounded by respectively insulating tape.

In an embodiment, the width of the insulating tape that primary coil and secondary coil both sides are surrounded by is respectively 2mm therein.

Therein in an embodiment, the height of the insulating tape that primary coil and secondary coil both sides are surrounded by and the enamel covered wire equal diameters of coiling.

In an embodiment, the number of plies covering at primary coil external application insulating tape parcel is 2 layers therein.

The beneficial effects of the utility model are: by be surrounded by the adhesive tape of insulation in coil both sides, the electrical distance of crossing of primary coil and secondary coil is improved greatly; The insulating tape of coil both sides and enamel covered wire equal diameters, make the insulating tape outside primary coil and secondary coil can tightly wrap up the coil covering in it, prevents coil generation physical displacement.Above-mentioned beneficial effect makes transformer of the present utility model have high pressure resistant, antivibration, anti-coil the characteristic such as to puncture

Wherein, 1 is skeleton, and 2 is stitch,, 3 is coil, 4 is the adhesive tape of coil both sides.

Embodiment

According to drawings and embodiments the utility model is described in further detail below.

The utility model mainly provides a kind of transformer that prevents that coil from puncturing, comprise transformer framework, stitch, primary coil, secondary coil, primary coil and secondary coil are to form with enamel covered wire coiling, primary coil is directly wound on transformer framework, cover at primary coil external application insulating tape parcel, secondary coil is wound on the insulating tape of primary coil outer wrapping, as shown in Figure 2, the utility model is surrounded by respectively insulating tape 4 in the both sides of primary coil and secondary coil, the width of insulating tape 4 is 2mm, the enamel covered wire equal diameters of the height of insulating tape 4 and coiling.In addition, the number of plies covering at primary coil external application insulating tape parcel is preferably 2 layers, can make has enough thick insulating barrier between primary coil and secondary coil, can make again in the situation that transformer framework size is constant, can more groups of coils of coiling as much as possible.

Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow the personage who is familiar with this art can understand the utility model content and be implemented, and can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection range of the present utility model.
