Wind turbine insulation treatment process

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.

Description

technical field [0001] The invention relates to the electrical field, in particular to a wind power generator insulation treatment process. Background technique [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 o...

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
