Abstract

The invention provides a rotor magnetic pole insulation structure. The rotor magnetic pole insulation structure comprises a magnetic pole iron core, an insulation part, a magnetic pole coil and an insulation flange; the magnetic pole iron core is sleeved with the magnetic pole coil; the insulation part is arranged between the magnetic pole iron core and the inner wall of the magnetic pole coil, and the inner wall of the magnetic pole coil and the magnetic pole iron core are spaced by the insulation part; and the insulation flange is arranged between the magnetic pole iron core and the end part of the magnetic pole coil and is used for separating the end part of the magnetic pole coil from the magnetic pole iron core. The invention also provides a method for improving rotor magnetic pole insulation, the insulation part and the insulation flange are arranged, the insulation part separates the inner wall of the magnetic pole coil from the magnetic pole iron core, the insulation flange separates the end part of the magnetic pole coil from the magnetic pole iron core, so that the magnetic pole coil can be effectively prevented from contacting with the magnetic pole iron core during use, and the insulation level of the magnetic pole coil is guaranteed.

Description

technical field [0001] The invention relates to the technical field of hydroelectric power generation, in particular to a rotor magnetic pole insulation structure and a method for improving rotor magnetic pole insulation. Background technique [0002] In hydropower stations, hydroelectric generators are usually used to generate electricity. Hydrogenerators refer to generators that use water turbines as prime movers to convert water energy into electrical energy. When the water flows through the water turbine, the water energy is converted into mechanical energy, and the rotating shaft of the water turbine drives the rotor of the generator, which converts the mechanical energy into electrical energy and outputs it. [0003] However, due to the design and manufacturing process defects of the rotor poles of some hydro-generators, the insulation level is very low. Often after a period of operation, the insulation will be reduced, which will affect the normal and safe operation o...
