Abstract
The utility model relates to a composite-insulation winding wire for a high-voltage frequency-conversion submersible motor. The composite-insulation winding wire for the high-voltage frequency-conversion submersible motor includes a copper lead, a corona-resisting shielding layer wrapping the copper lead, a crosslinked polyethylene insulating layer wrapping the corona-resisting shielding layer and a composite polyolefin protection layer wrapping the crosslinked polyethylene insulating layer. By using the composite-insulation winding wire for the high-voltage frequency-conversion submersible motor provided by the utility model, damages of the insulating layer of a conductor caused by high-frequency harmonics and harmonic voltage can be eliminated, and the high-voltage frequency-conversion submersible motor can work normally in high harmonic frequency and under generated harmonic high-voltage impact.
Description
Technical field
The utility model relates to the special-purpose winding wire of high-pressure frequency-conversion submersible motor that a kind of high pressure resistant, anti-corona uses under the high-pressure frequency-conversion condition.
Background technology
The high-pressure immersed electromotor that uses does not at present also generally adopt converter technique, in case adopt the varying frequency starting operation, winding wire will bear the voltage of several times and the impact of higher harmonic frequencies, and the winding wire insulation is partial breakdown in a short period of time, causes damage.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can overcome because of frequency-conversion high-frequency harmonic wave and the harmonic voltage destruction to conductor insulation, makes the special-purpose winding wire of high-pressure frequency-conversion submersible motor that the high-pressure frequency-conversion submersible motor can normal operation under the harmonic wave impacting with high pressure of higher harmonic frequencies and generation.
The utility model adopts following technical scheme:
A kind of high-pressure frequency-conversion compound inslation submersible motor winding wire is characterized in that it comprises that copper conductor, bag are put the layer of anti-corona shielding the copper conductor outside, bag is put the crosslinked polyetylene insulated layer the layer of anti-the corona shielding outside and wrapped the compound polyolefin overcoat of putting outside crosslinked polyetylene insulated layer.
Good effect of the present utility model is as follows:
The utility model comprises copper conductor, wraps high-tension shielding material and crosslinked polyetylene insulated (and carry out irradiation technique) of extrusion molding outside screen of putting outside copper conductor, extrusion molding high-performance poly alkene overcoat outside crosslinked polyetylene insulated layer.The utility model high-pressure frequency-conversion compound inslation submersible motor winding wire, the frequency-conversion harmonic that produces because of frequency conversion and harmonic voltage have been overcome to the destruction of conductor insulation, guarantee the reliability service of high-pressure frequency-conversion submersible motor, the utility model conductor adopts copper free wire through softening Passivation Treatment, guarantee not oxidation of softness, screen adopts semi-conductive screen extrusion molding or the wrapped sintering of the composite membrane of anti-the corona, the corona voltage that produces because of frequency conversion is played shielding action, insulating barrier adopts crosslinked polyethylene extrusion molding irradiation technique, can bear the high frequency of the pulse harmonic wave that produces because of frequency conversion, high pressure, the frequent impact of high temperature, overcoat adopts the high-performance composite polyolefine material, extrusion molding guarantees the winding wire of this structure outside crosslinked polyetylene insulated layer, under harsh conditions, the steady operation of mechanical strength and electrical property.
Description of drawings
Accompanying drawing is structural representation of the present utility model
In the accompanying drawings: 1. copper conductor, the 2. layer of anti-corona shielding the, 3. crosslinked polyetylene insulated layer, 4. polyolefin overcoat.
Embodiment
As shown in drawings, the utility model comprises copper conductor 1, and bag is put the layer of anti-corona shielding the 2 outside copper conductor, crosslinked polyetylene insulated layer 3 and extrusion molding the compound polyolefin overcoat 4 crosslinked polyetylene insulated layer 3 outside of extrusion molding outside the layer of anti-corona shielding the 2.
The utility model high-pressure frequency-conversion compound inslation submersible motor winding wire has overcome the high-frequency harmonic that produces because of high-pressure frequency-conversion and harmonic voltage to the destruction of conductor insulation, makes the high-pressure frequency-conversion submersible motor be able to reliable and stable operation.The utility model conductor adopts copper free wire to guarantee non-oxidizing copper conductor 1 through softening Passivation Treatment, the layer of anti-corona shielding the 2 adopts semi-conductive screen extrusion molding or the wrapped sintering of the film of anti-the corona, harmonic voltage is produced shielding action, adopt crosslinked polyethylene as insulating barrier, can bear the frequent impact because of high frequency that the high-pressure frequency-conversion harmonic wave produces, high pressure, high temperature, adopt the steady operation of winding wire that high-performance poly alkene overcoat 4 guarantees these structures mechanical strength and electrical property under harsh conditions.
