Assembly process for stator of 3MW permanent magnet synchronous wind-driven generator

Abstract

The invention relates to an assembly process for a stator of a 3MW permanent magnet synchronous wind-driven generator. The process comprises the following steps of: A, assembly of a stator tooth pressing plate; B, lamination of a stator core; C, assembly of a cooling system; D, assembly of the stator; and E, paint dipping and coating of the stator. By the assembly process for the stator of the 3MW permanent magnet synchronous wind-driven generator, the assembly is convenient; core lamination effects are good; radiation efficiency can be effectively improved; a cooling water pipe has good pressure resistant effects and high reliability; and a coil has high insulating and sealing properties.

Description

technical field [0001] The invention relates to a stator assembly process, in particular to a stator assembly process applied to a 3MW permanent magnet synchronous wind power generator. Background technique [0002] With the increasingly serious energy crisis, the development of new energy sources has attracted widespread attention. Among them, wind energy has been widely used because of its simple acquisition and abundant stock. In the process of utilizing wind energy, wind power generators are one of the most important devices; in order to obtain enough wind energy, wind power generators are usually bulky, so their assembly is extremely cumbersome and complicated. Operations such as doubling and varnish dipping are often complicated; during the assembly process of the stator of an ordinary wind turbine, a large CNC machine tool is required for precise slotting before the bead can be accurately installed to form the stator tooth pressure plate, so the assembly is not only e...

In the process of utilizing wind energy, wind power generators are one of the most important devices; in order to obtain enough wind energy, wind power generators are usually bulky, so their assembly is extremely cumbersome and complicated. Operations such as doubling and varnish dipping are often complicated; during the assembly process of ordinary wind turbine stators, large-scale CNC machine tools are required for precise slotting before the beading can be accurately installed to form the stator tooth pressure plate, so the assembly is not only expensive, but also Time-consuming, labor-intensive, and inefficient; and the lamination coefficient of the iron core punching sheet is too low during the lamination process, resulting in low quality or even scrapping of the entire stator. In addition, the water pipes used for cooling are usually directly welded when connected, so the water pipes The pressure resistance effect is not good, and long-term use is prone to leakage accidents; at the same time, no sealing measures are taken for the coil at the notch of the iron core, resulting in poor sealing effect in the entire stator slot and affecting insulation performance
