Abstract

The present invention relates to the wind generation device manufacturing field, especially to a manufacturing of an SMC insulation end cover for a wind generator. Compared to the prior art, the manufacturing has the advantages in that: (1) the long-term heat-resistance temperature index of SMC materials is larger than 170 DEG C, the bending intensity of the SMC materials is larger than 220 MPa, the material glass fiber reinforcement of the SMC materials is about 43%, and the SMC materials have extremely high mechanical strength; (2) the SMC insulation end cover is subjected to mould pressing once forming and is high and uniform in density, the mechanical strength of each direction is higher than an insulation end cover without a latitude band and is uniform, and the SMC insulation end cover does not need secondary processing and is nonhygroscopic; and (3) the SMC insulation end cover does not perform gluing, has maintainability and has the life which is longer in several times than the insulation end cover without a latitude band.

Description

technical field [0001] The invention relates to the field of wind power generation equipment manufacturing, in particular to the manufacture of an SMC insulating end cover for a wind power generator. Background technique [0002] my country's wind power generation has gone through a period of rapid development, and the current generators have entered the maintenance period one after another. The wind turbine is installed at a height of tens of meters. Once a fault occurs, it is extremely inconvenient to hoist and repair. Therefore, all components of the wind turbine are required to be reliable and have a long life. Since wind power generation needs to use the inverter to transmit power to the grid, in order to prevent the high-frequency current generated by the inverter, the generator adopts an insulating end cover structure. [0003] At present, in the operation of wind turbines, the insulating end cover with wound latitude-free tape structure is often used to ensure the i...
