Abstract
The utility model relates to a corona-resistance leader cable for a variable frequency motor, comprising a conductor, a packing material and an outer sheath. An aluminium tape lapped covering layer and a braided copper screen layer are arranged on the cable core which is formed by a three-phase cable core, the outer sheath is sheathed on the braided copper screen layer in an extruding way, and a nanometer TiO2 composite polyamide-imide insulating layer is lapped-covered on the outer surface of the conductor of a copper wire stranded bundle. In the utility model, the structure of the cable is simplified, the nanometer TiO2 composite polyamide-imide insulating layer increases the resistance of partial discharge and degradation of the cable and eliminates the generation of the partial discharge; the corona-resistance leader cable has good electric conductivity and heat stability, is helpful to diffuse accumulated charge, has high heat conductivity, can dissipate medium heating rapidly, and the cable can effectively achieve the requirements of high-frequency impulse voltage resistance, corona-resistance performance and insulating property.
Description
Technical field
The utility model relates to a kind of special cable, relates in particular to a kind of variable-frequency motor with anti-corona jump lead.
Background technology
Along with the rapid expansion that variable-frequency motor is used, variable-frequency motor jump lead problem in useful life but becomes increasingly conspicuous.Variable-frequency motor jump lead premature damage is recurrent thing, and the life-span that has has only 1-2, have in addition have only some months just to damage.Discover that the resistant to partial discharges of motor leading and connecting cable under the frequency conversion condition is the main cause of its damage.Existing anti-corona jump lead is provided with the anti-corona layer of the fluororesin polyamidoimide of anti-the corona between conductor and insulating barrier, the cable of this kind structure includes anti-corona layer and insulating barrier simultaneously, make construction of cable more complicated, increased production cost, anti-corona effects is undesirable, and useful life is short.
The utility model content
The utility model provides the good variable-frequency motor of a kind of corona effects simple in structure, anti-with anti-corona jump lead in order to overcome the above problems.
The technical solution of the utility model is: a kind of variable-frequency motor is with anti-corona jump lead, include conductor, packing material, oversheath, the cable core of three-phase core stranding is provided with aluminium strip lapping layer and copper wire woven shield, oversheath is extruded on the copper wire woven shield, and copper wire twisted bundles conductor outer surface is surrounded with nano TiO 2 composite polyamide acid imide insulating barrier.
Described oversheath is a silicon rubber.
The utility model has the advantages that: simplified the structure of cable,, made it increase the resistance that cable local discharge is degraded, eliminated the generation of partial discharge at the wrapped nano TiO 2 composite polyamide of copper wire twisted bundles conductor outer surface acid imide insulating barrier.Nano TiO 2 composite polyamide acid imide insulating barrier is again the material of a kind of conductance and better heat stability, it helps diffusion charge accumulation and heat conductivity higher, the dielectric heat of dissipation itself makes cable reach the requirement of anti-high-frequency pulse voltage, corona-resistance property and insulation property effectively rapidly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is conductor among the figure, the 2nd, and insulating barrier, the 3rd, packing material, the 4th, aluminium strip lapping layer, the 5th, screen, the 6th, oversheath.
Embodiment
A kind of variable-frequency motor is with anti-corona jump lead, include conductor 1, packing material 3, oversheath 6, the cable core of three-phase core stranding is provided with aluminium strip lapping layer 4 and copper wire woven shield 5, oversheath 6 is extruded on the copper wire woven shield 5, copper wire twisted bundles conductor 1 outer surface is surrounded with nano TiO 2 composite polyamide acid imide insulating barrier 2, and described oversheath 6 is a silicon rubber.
Claims (2)
1. a variable-frequency motor is with anti-corona jump lead, include conductor, packing material, oversheath, the cable core of three-phase core stranding is provided with aluminium strip lapping layer and copper wire woven shield, oversheath is extruded on the copper wire woven shield, it is characterized in that: copper wire twisted bundles conductor outer surface is surrounded with nano TiO 2 composite polyamide acid imide insulating barrier.
