The utility model proposes a kind of insulated wires 100.

Referring to figs. 1 to the structure diagram one that 2, Fig. 1 is the utility model insulated wire embodiment；Fig. 2 is another in Fig. 1 The structure diagram at visual angle.

The insulated wire 100, including core component 10, the insulated wire 100 further includes is wrapped in the core component successively 10 silk covering 30 and insulating layer 50.

The outside of the online core assembly 10 of technical solutions of the utility model is enclosed with a covering 30 and insulating layer 50 successively, wherein This thread covering 30 can with the dimensional stability, flexibility and impregnation performance of increase line core assembly 10, due to the setting of silk covering 30, So that the cross section of core component 10 is not susceptible to deform during the winding process, reduces and set using the coil of the insulated wire 100 Error in meter and installation process；Further, which is used for the inside that seawater is prevented to immerse insulated wire 100 and corrodes Core component 10 improves the NBC protective performance of the insulated wire 100, prolongs the service life.

The silk covering 30 includes being wound in the textile yarn of the core component 10.

Further, the textile yarn is nylon or terylene.

100 outside of the utility model insulated wire is intensive to be wound with textile yarn and forms a covering 30, due to silk covering 30 Setting so that the cross section of core component 10 is not susceptible to deform during the winding process, reduces the coil using the insulated wire 100 Error during design and installation further, is detected by experiment, compared to the insulated wire for being not provided with a covering, sheet The insulated wire 100 of utility model setting silk covering 30 has preferable heat dissipation performance.

It is to be appreciated that nylon or terylene material can be selected in textile yarn, there is preferable toughness.

The insulating layer 50 includes the insulating tape for winding the silk covering 30.

Insulating tape is securely wrapped in core component 10 by using the form of winding in the utility model embodiment, due to exhausted Marginal zone has been completed the production before wrapped processing, its thickness can be accomplished thinner during independent processing and fabricating insulating tape, therefore is processed The insulating layer 50 of insulated wire 100 afterwards is thinner, volume smaller, occupies smaller space, space availability ratio higher.

The axial direction of the insulating tape and the core component 10 is wound, and the insulating tape is during the winding process in an inclination angle Partly overlap setting.

Specifically, during the degree of overlapping of insulating tape is by its own winding band, the axial direction of insulating tape and core component 10 Between angle of inclination determined.Degree of overlapping determined in insulating tape winding process, the number of plies that insulating tape itself is overlapped mutually, from And determine its thickness.

Further, ranging from the 30~80% of the Duplication of the insulating tape, so that the insulating tape has preferably absolutely Edge effect.Optionally, the ranging from 40-45% of the degree of overlapping of insulating tape.It should be noted that in the utility model embodiment simultaneously The degree of overlapping of insulating tape is not limited specifically, other can reach the degree of overlapping of the insulating tape of insulation effect also in this practicality Within novel protection domain.

Ranging from 0.007~0.08mm of the thickness of the insulating tape, so that the insulating tape has preferable insulation effect. Optionally, the ranging from 0.007-0.008mm of the thickness of insulating tape.It should be noted that in the utility model embodiment not The thickness of insulating tape is specifically limited, other can reach the thickness of the insulating tape of insulation effect also in the utility model Within protection domain.

Ranging from 6~25mm of the width of the insulating tape, so that the insulating tape has preferable insulation effect.It is optional Ground, the ranging from 7-8mm of the width of insulating tape.It should be noted that not to the width of insulating tape in the utility model embodiment Degree is specifically limited, other can reach the width of the insulating tape of insulation effect also the scope of protection of the utility model it It is interior.

The insulating tape material be polyester film, polyester tape, polyester hot melting film, Kapton, polyimides glue Band, polyimides hot melt film, Teflon orientation film or aramid fiber thin paper, so that the insulating tape has preferable insulation effect.It needs It is noted that not limited specifically the material of insulating tape in the utility model embodiment, other can reach insulation The material of the insulating tape of effect is also within the protection scope of the utility model.

The core component 10 includes being set up in parallel or more mutually twisted cores 11, the more cores 11 are wrapped in In the silk covering 30, which becomes an entirety by being set up in parallel or being mutually twisted for its more cores 11, Textile yarn and insulating tape are wrapped up successively as more cores 11 of an entirety, so that the periphery of core component 10 levels off to circle Shape.

11 material of core is copper.

It is to be appreciated that using transformer coil of the copper as core material, have high reliability, high mechanical properties and compared with Small size.

The surface of the core 11 is coated with protective layer, which is chosen as insulated paint or copper complex overlay film so that Mutually insulated between core 11, and have certain resistance to corrosion, wherein causing the thickness of protective layer using copper complex overlay film Degree is thinner, so as to reduce the outer diameter of core 11, realizes the miniaturization of coil, and improve the insulated wire 100 of per unit volume Occupation efficiency.

The utility model also proposes a kind of marine transformer, which includes the insulated wire 100, the insulation The concrete structure of line 100 is with reference to above-described embodiment, since this marine transformer employs whole technologies of above-mentioned all embodiments Scheme, therefore all advantageous effects at least caused by the technical solution with above-described embodiment, this is no longer going to repeat them.

The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention, It is every under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes It changes or directly/is used in other related technical areas indirectly and is included in the scope of patent protection of the utility model.
