Problems solved by technology
If the air gap between the stator and rotor is not uniform after the assembly is completed, the generator will run unstable and easily vibrate. If the air gap is too large, the excitation current will increase. If the air gap is too small, the stator and rotor may collide. In severe cases, the stator insulation will be damaged and short circuit will occur. breakdown
[0003] Although the rotor is first adjusted to the level of the rotor before the assembly and the rotor is adjusted after the rotor falls above the stator, there will still be a phenomenon of fasteners being seized during the interconnection of the various parts of the wires.
Seriously affect the quality of the generator after assembly and shorten the life of the unit

The invention provides a support protection tool of a suit-stator of an MW (megawatt)-level permanent magnetic direct drive wind driven generator. The support protection tool comprises at least two support upright column seamings, jacks respectively arranged on the upper end faces of the support upright column seamings, and support connection angle iron for fixing and connecting the support upright column seamings by bolts. The support protection tool is reliable and safe in performance. By utilizing the support protection tool, support protection of a stator of the MW-level permanent magnetic direct drive wind driven generator is safely realized with good quality.
Description
technical field [0001] The invention relates to the assembly of a MW class generator, in particular to a MW class permanent magnet direct-drive wind power generator set stator support protective tooling. Background technique [0002] MW (megawatt in English, that is, power unit: megawatt) permanent magnet direct drive generator is mainly composed of rotor, stator, rotating shaft, fixed shaft, bearings, etc. During the assembly process, the stator is supported on the protective tooling, and the The rotor is slowly inserted into the stator. If the air gap between the stator and rotor is not uniform after the package is completed, the generator will run unstable and easily vibrate. If the air gap is too large, the excitation current will increase. If the air gap is too small, the stator and rotor may collide. In severe cases, the stator insulation will be damaged and short-circuited. breakdown. [0003] Although the rotor is first adjusted to the level of the rotor before the...
