Abstract

The utility model discloses a novel dredging and anti-freeze frequency conversion cable which comprises a core set, a padding layer, an inner wrap layer, a shielding layer and a protection sleeve layer from inside to outside in sequence. The core set comprises three main cores, three sub-cores, a semiconductive shielding layer of a conductor, insulation layers, an insulation semiconductive shielded layer and a copper belt layer. Three main cores and three sub-cores are arranged symmetrically at intervals. The semiconductive shielding layer of the conductor, the insulation layers, the insulation semiconductive shielded layer and the copper belt layer are sequentially wrapped outside the three main cores. The insulation layers are wrapped outside the sub-cores, wherein the protection sleeve layer is provided with a dredging and anti-freeze layer of perfect capacities of being anti-freeze and self-cleaning at the outside. The novel dredging and anti-freeze frequency conversion cable overcomes the defects in an existing frequency conversion cable of loss of a frequency conversion function of the cable due to easy freezing, poor water-proof performance and poor pollution-proof performance and has the advantages of being effective in water-proof performance, freeze-resistance performance and pollution-proof performance.

Description

A kind of novel hydrophobic anti-freeze frequency-changing cable

Technical field

The utility model belongs to field of cables, is specifically related to a kind of novel hydrophobic anti-freeze frequency-changing cable.

Background technology

At present, along with the development of alternating frequency conversion technique, the application of frequency conversion system is also more and more universal, and frequency-changing cable can avoid the high order harmonic component of generation in service that its power supply, control loop are produced interference, perhaps be subjected to the interference of external electromagnetic signal, this also is the most important performance requirement of frequency-changing cable.Progress along with society, converter technique has been used in various fields, therefore, different environment has had special requirement to frequency-changing cable, for example, in the area that humidity is easily frozen, general frequency-changing cable restrictive coating may be because of making moist even freeze for a long time, thereby cause cable feature to be affected.

The utility model content

The technical problems to be solved in the utility model is to cause the shortcoming of frequency-changing cable loss function for existing frequency-changing cable water proof anti-soil weak effect, easy freezing, provide a kind of shield effectiveness good, effectively waterproof, antifouling, anti-freeze a kind of novel hydrophobic anti-freeze frequency-changing cable.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of novel hydrophobic anti-freeze frequency-changing cable, comprise successively from the inside to the outside the core group, packed layer, interior lapping layer, screen and restrictive coating, the core group comprises three master cores and three by-pass cores, the conductor semiconductive shielding layer, insulating barrier, insulation semiconductive shielding layer and copper strips layer, three master cores and three by-pass cores are apart from one another by symmetric arrays, the conductor semiconductive shielding layer, insulating barrier, insulation semiconductive shielding layer and copper strips layer are wrapped in outside three master cores successively, by-pass core outer wrapping insulating barrier, wherein, restrictive coating is outside equipped with hydrophobic anti-caking ice sheet.

Adopt a kind of novel hydrophobic anti-freeze frequency-changing cable of technical solutions of the utility model, because restrictive coating is outside equipped with hydrophobic anti-caking ice sheet, hydrophobic anti-caking ice sheet is to utilize " lotus leaf effect " principle, adopt liquid crystal templated mechanism and conventional coatings curing process to organically combine, choose the polymer of excellent combination property, adopt an one-step film forming method, easy, economically at engineering material aluminium, copper, iron, the surface constructions such as magnesium alloy go out nanometer fluoropolymer fibers and the hydrophobic anti-icing coatings material of micro-nano texture " artificial lotus leaf ", this material has good hydrophobic function, can be widely used in metal, plastics, rubber, on the materials such as glass.Thereby be used for cable and can make cable have the anti-freeze ability of water proof anti-soil, to avoid affecting cable feature.

Further, a kind of novel hydrophobic anti-freeze frequency-changing cable, wherein, to be that proof copper-wire braided or copper strips are wrapped form described screen.Screen and symmetrical cable core interact the anti-interference of frequency-changing cable is better embodied.

Adopt a kind of novel hydrophobic anti-freeze frequency-changing cable of technical solutions of the utility model, with respect to common frequency-changing cable, hydrophobic anti-caking ice sheet has excellent antifouling, waterproof, icing protection, avoid frequency-changing cable to be affected at environment performances such as moist, foggy or the Frost's Descent, so that frequency-changing cable can normally use under particular surroundings for a long time.

Description of drawings

Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:

Fig. 1 is the schematic diagram of a kind of novel hydrophobic anti-freeze frequency-changing cable embodiment of the utility model.

Embodiment

As shown in Figure 1, a kind of novel hydrophobic anti-freeze frequency-changing cable of the utility model, comprise successively from the inside to the outside the core group, packed layer 7, interior lapping layer 8, screen 9 and restrictive coating 10, the core group comprises three master cores 1 and three by-pass cores 2, conductor semiconductive shielding layer 3, insulating barrier 4, insulation semiconductive shielding layer 5 and copper strips layer 6, three master cores 1 and three by-pass cores 2 are apart from one another by symmetric arrays, conductor semiconductive shielding layer 3, insulating barrier 4, insulation semiconductive shielding layer 5 and copper strips layer 6 are wrapped in outside three master cores 1 successively, by-pass core 2 outer wrapping insulating barriers 4, wherein, restrictive coating 10 is outside equipped with hydrophobic anti-caking ice sheet 11; To be that proof copper-wire braided or copper strips are wrapped form screen 9.

In specific implementation process; adopt three master cores 1 and three by-pass cores 2; conductor semiconductive shielding layer 3; insulating barrier 4; insulation semiconductive shielding layer 5 and copper strips layer 6 are wrapped in outside three master cores 1 successively; by-pass core 2 outer wrapping insulating barriers 4; screen 9 adopts that copper strips is wrapped to be formed; certainly; if adopt three cores; conductor semiconductive shielding layer 3; insulating barrier 4; insulation semiconductive shielding layer 5 and copper strips layer 6 are wrapped in outside three cores successively; or screen 9 adopts proof copper-wire braided to form; also all within the claim protection range; packed layer 7 is filled between the core group; interior lapping layer 8; screen 9 and restrictive coating 10 are wrapped in outside the packed layer 7 successively; hydrophobic anti-caking ice sheet 11 is located at outermost layer; be wrapped in outside the restrictive coating 10; when frequency-changing cable is in humidity; foggy; in the time of in the environment such as the Frost's Descent; the principle of hydrophobic anti-caking ice sheet 11 its " lotus leaf effect " of performance; play waterproof; anti-freeze effect; thereby protection frequency-changing cable; so that restrictive coating 10 is not soaked in water or do not freeze, thereby avoid affecting its serviceability.

For a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement, these also should be considered as protection range of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
