Problems solved by technology

[0002] Due to the rapid development of the new energy industry, the production technology of wind turbines is also being updated quickly. The early production of wind turbines has been discontinued after 2-3 years of operation, and it is very difficult to replace them after problems occur. Datang Jingtaisha Tangzi Wind Farm is equipped with 30 CSR WT1650 double-fed wind turbines, which have been put into operation for 4 years. In November 2015, a WT1650 wind turbine of CSR found abnormal sound during dynamic inspection. Please contact the NGC manufacturer The personnel further inspected and judged that the fault was electrical corrosion of the generator bearing and the damage of the bearing insulation room caused by it, and the bearing and the bearing insulation room needed to be replaced to restore the operation of the fan. However, the manufacturer of this type of bearing insulation room has stopped production and needs to be customized, and the production cycle is as long as possible. More than 2 months, and the cost is 3 times higher than the previous purchase. Calculated based on the fan outage for 2 months, the company's economic benefits will be directly or indirectly affected by about 300,000

Embodiment Construction

[0012] The content of the bearing insulation treatment method for CSR WT1650 wind power generator of the present invention will be described in detail below in conjunction with the embodiments.

[0013] 1. Removal of generator rear end cover and bearing insulation chamber

[0014] Remove the generator rear end cover together with the bearing insulation chamber, and take it to the ground for processing. When the inner ring of the generator rear end cover is heated to 90 degrees Celsius, the insulation chamber and the end cover are separated. After disassembly, the insulating flat pad insulation can be observed In the damaged place, use a flat file to file the electric burn part into a smooth 45-degree bevel, and there should be no burned black spots at the groove.

[0015] 2. Repair of the vertical insulation pad between the generator bearing insulation room and the end cover

[0016] Use epoxy resin insulation board as the repair material, cut out the approximate shape with s...

Abstract

The invention discloses an insulating treatment technology of a wind generator, and relates to the field of electrics. A treatment method is provided for the damage to a generator bearing chamber caused by electrical erosion of a bearing of the WT1650 wind generator of the China Southern Locomotive. A damaged insulation pad is repaired by an epoxy resin insulation plate; a cylindrical insulation pad between a generator bearing insulation chamber and an end cover is fabricated again by a glass tape, insulating varnish and highland barley paper; and an insulation value in each step in the reinstallation process can be measured at any time. The insulating treatment technology has the beneficial effects that the money is saved; the maintenance duration is shortened; the economic benefits are greatly improved; the operation is simple; the maintenance is convenient; the bad conditions are effectively overcome; the operation is stable; and the cost is reduced.
