Abstract

The invention relates to a motor rotor connecting flexible cable, which comprises a copper conductor and a silicon rubber insulating layer, and is characterized in that: an irradiation crosslinked polyolefin sheath is arranged on an outer surface of the silicon rubber insulating layer; the irradiation crosslinked polyolefin sheath comprises the following components in percentage by weight: 25 to 35 percent of EVA resin, 5 to 15 percent of calcium carbonate, 50 to 65 percent of magnesium hydroxide, and 1 to 5 percent of antioxidant 1010, wherein the grain fineness of the calcium carbonate is 700 to 1,000 meshes. The invention also relates to a method for preparing the motor rotor connecting flexible cable. The cable insulated sheath has high mechanical strength and is tough.

Description

A kind of motor rotor connecting flexible cable and preparation method thereof
One, technical field
The present invention relates to a kind of motor rotor connecting flexible cable, relate in particular to wind power generation double fed electric machine rotor connecting flexible cable and preparation method thereof.
Two, background technology
Present more than high-power 1.5M watt the internal rotor of wind power generation double-fed braille connect flexible cable and all adopt the silicon rubber insulation motor leading and connecting flexible cable, it mainly is made up of copper conductor and silicone rubber insulation layer, because the bad mechanical property of silicon rubber own, in use because the running of rotor continuous high speed, cable and rotor hole wall long term wear, cause the silicone rubber insulation layer breakage of cable, thus cause opening circuit and motor coil burn.Because wind-driven generator is installed in cat head, causes every about great number maintenance cost more than 500,000 yuan.
Three, summary of the invention
At above-mentioned shortcoming, the object of the present invention is to provide a kind of mechanical strength height of cable insulation jacket, the motor rotor connecting flexible cable of cracky not.
Technology contents of the present invention is a kind of motor rotor connecting flexible cable, comprises copper conductor and silicone rubber insulation layer, it is characterized in that being provided with the cross-linking radiation polyolefin jacket in the appearance of silicone rubber insulation layer; The component and the percentage by weight of its cross-linking radiation polyolefin jacket are as follows:
EVA resin 25~35
Calcium carbonate 5~15
Magnesium hydroxide 50~65
Antioxidant 1010 1~5
Wherein the grain fineness of calcium carbonate is 700~1000 orders.
Another object of the present invention is to provide the preparation method of above-mentioned motor rotor connecting flexible cable.
A kind of motor rotor connecting flexible cable preparation method, its step is as follows:
On copper conductor extrude one deck silicone rubber insulation layer, make connecting flexible cable (1), earlier;
(2), carry out granulation after EVA resin, calcium carbonate, magnesium hydroxide and antioxidant 1010 mixed as following weight percent, make each component plasticizing evenly, make the polyolefin insulation material;
EVA resin 25~35
Calcium carbonate 5~15
Magnesium hydroxide 50~65
Antioxidant 1010 1~5
(3), the polyolefin insulation material that makes in the step (2) is extruded in the appearance of the connecting flexible cable that makes in the step (1);
(4), irradiation accelerator is executed and is accompanied 20~30KV energy, radiation dose is 15~18Mrad, to circulate around 10~15 roads in the connecting flexible cable introducing accelerator that make in the step (3), carry out cross-linking radiation through 15~18 meters/minute linear speeds, the heat extension of cable insulation is reached between 40~50%, be the finished product motor rotor connecting flexible cable.
The present invention adds at the silicone rubber insulation layer of cable and extrudes one deck cross-linking radiation polyolefin as sheath, can improve the resistance to wear of cable in rotor greatly, and can reach the heatproof index equally.
The advantage that the present invention has is:
1, the present invention has squeezed one deck cross-linking radiation polyolefin jacket owing to the silicone rubber insulation layer appearance at cable adds, improved the mechanical performance of cable greatly, have only 5Mpa to bring up to more than the 12.5Mpa by original tensile strength, thereby significantly improve the resistance to wear of cable when cable is used.
2, the present invention is owing to the cardia that uses at motor, the double-fed wind power generator wind-engaging is to constantly flickering, cable has the stretching of certain distance, adds to have squeezed the cross-linking radiation polyolefin jacket, and the elongation at break of cable has 150% of original silicon rubber insulated cable to bring up to more than 250%.
3, the present invention is because cross-linking radiation polyolefin jacket anti-wear performance is good, the motor that can the significantly reduce wind-driven generator accident that opens circuit.
Four, description of drawings
Fig. 1 is a structural representation of the present invention.
Five, embodiment
Example 1: a kind of motor rotor connecting flexible cable preparation method, its step is as follows:
On copper conductor extrude one deck silicone rubber insulation layer, make connecting flexible cable (1), earlier;
(2), be to carry out granulation after 800 purpose calcium carbonate, 1.1Kg magnesium hydroxide and 0.06Kg antioxidant 1010 mix with 0.6KgEVA resin, 0.24Kg fineness, make each component plasticizing evenly, make the polyolefin insulation material;
(3), the connecting flexible cable that will make in step (1) draws the feeding extrusion device by tension device, simultaneously the polyolefin insulation material that makes in the step (2) sent into extrusion device, makes insulating material be extruded in the connecting flexible cable appearance; The hauling speed of connecting flexible cable is 5 meters/minute, and the traction tension is 320N;
(4), irradiation accelerator is executed and is accompanied the 25KV energy, radiation dose is 16Mrad, the connecting flexible cable that makes in the step (3) is introduced in the accelerator circulated around 15 roads, carries out cross-linking radiation through 16 meters/minute linear speeds, make the heat extension of cable insulation reach 45%, be the finished product motor rotor connecting flexible cable; The finished product motor rotor connecting flexible cable comprises copper conductor 1 and silicone rubber insulation layer 2 as shown in Figure 1, it is characterized in that being provided with cross-linking radiation polyolefin jacket 3 in the appearance of silicone rubber insulation layer 2.
