Background technology
At present, high-voltage wound rotor motor mainly application with the requirement of the detent torque such as cement industry, mine hoisting compared with Datong District
The place of Shi Yaoqiu Fraquent starts.In the prior art, high-voltage wound rotor motor is using the wound rotor line of double-deck hard winding
Circle, rotor is provided with rotor slot and notch is semi-closed port shape, and wound rotor coil is from rotor slot one end through the other end, then in groove
Mouth insertion slot wedge, realizes the setting-in of wound rotor coil.The wound rotor coil windings number of turn is few, and typically single line is used per every layer of groove
Copper strap wire is enclosed, because winding not necessarily belongs to and must insulated between same phase, two layers of winding in same groove.But domestic coiling at present
The insulation system of rotor coil is more based on F grades, but for the niche market demand of high-temperature resistant index (more than 180 DEG C), F grades absolutely
Edge can not meet actual operation requirements.
The content of the invention
It is an object of the invention to provide a kind of method for coating of wound rotor coil, proof voltage, the heatproof of coil are improved
Level, while constituting good Insulation Coordination with motor rotor slot, it is ensured that the reliable and stable operation of motor.
To achieve these goals, the present invention takes following technical scheme：A kind of method for coating of wound rotor coil, bag
Include following steps：A, flat copper coil are divided into section and the outer section of groove between groove；The first layer covering material of the outer section of S, groove is thin for polyimides
The second layer covering material of the first layer covering material of section and the outer section of groove is all silicone powder mica tape between film strips, groove；D, in groove
Between section continue to outer cladding thermal polycondensation ester film band, section continues to outer cladding alkali-free glass wool band outside groove.
In above-mentioned technical proposal, silicone powder mica tape has good pliability, with higher electric, electric heating property
And mechanical performance, as the second layer of section outside the first layer of section between groove, groove；Pyrocondensation mylar tape is in flat copper coil
The outermost layer of section between groove, it is heat shrink wrap material, and smooth outer surface, and section is interted to rotor slot between being easy to groove；Outside groove
The first layer polyimide film tape of section equally has resistant to elevated temperatures mechanical performance；Alkali-free glass silk ribbon as section outside groove outermost
Layer is worked out by alkali-free glass fibre, and high temperature resistant, insulation, stretching resistance are strong, and the outer section of groove needs bending so using alkali-free glass wool
Band adds structural strength, and what is used is that high-temperature resistant material coats flat copper coil for H class B insulation structures, is resistant to more than 180 DEG C
High temperature, and the good thickness of material property used is uniform, and increase flat type copper wire that will not be excessive, which is enclosed, uses volume, with rotor slot
Good interspersed cooperation is formed, insulation high-temperature-resistant is ensured in use, it is ensured that motor is reliably run.
