Background
The pole coil is used as a core component of the hydro-generator rotor, and has high requirements on the external dimension and the electrical performance in the production and manufacturing process.
In the manufacturing process of the magnetic pole coil, the copper bar is generally manufactured in a spiral mode through edgewise winding or welding, and epoxy glass grey cloth or gummed paper is padded between an upper circle of copper wire and a lower circle of copper wire and is integrated through hot pressing. After the magnetic pole coil is hot-pressed and passes an electrical test, the magnetic pole coil is required to be incapable of deforming or displacing among copper wires during transportation or hoisting, and particularly during the process of sleeving the magnetic pole coil into the magnetic pole core, because the inner cavity of the magnetic pole coil and the magnetic pole core are required to be tightly matched, a hanger cannot penetrate into the magnetic pole coil, the whole process can only hoist the periphery of the magnetic pole coil.
The weight of the general large-scale magnetic pole coil can reach 700-6000 kg, even heavier, and each turn of the large-scale magnetic pole coil is only bonded by the viscosity of epoxy glass grey cloth or gummed paper after hot pressing, so that the large-scale magnetic pole coil cannot bear large weight.
