Abstract

The invention provides a 2MW wind turbine notch potting process. The process includes the steps of sticking a double-sided foam adhesive and the lower edge of the outer surface of transparent composite foil in a parallel and level mode and closely winding and tensioning a round of the notched edge of the outer circle of a stator with the double-sided foam adhesive; cutting a glass fiber mat into rectangular pieces to be filled onto the surface of a groove wedge and tightly sticking and fixing the upper end of the glass fiber mat to the lower end of the double-sided foam adhesive with a transparent adhesive tape; filling potting adhesive to the bottom of the transparent composite foil to complete potting. According to the 2MW wind turbine notch potting process, the glass fiber mat is used for filling the surface of the groove wedge, and then the transparent adhesive tape is used for sticking and fixing for further enabling the entire outer surface of the 2MW stator to approximately have the surface of a cylinder, so that potting adhesive leakage during the potting of a 2MW direct drive permanent magnet wind turbine notch can be effectively prevented, and the surface formed through curing with the notch potting adhesive is smooth and attractive in appearance.

Description

technical field [0001] The invention belongs to the field of filling and sealing slots of MW wind power generators, and in particular relates to a filling and sealing process for slots of 2MW wind power generators. Background technique [0002] In the field of wind power generator technology, in order to prevent external moisture from entering the stator and reduce the insulation resistance of the motor coil, MW-level direct-drive permanent magnet wind turbines need to inject potting glue into the slot of the stator for protection. After the potting glue is cured, it can effectively prevent external moisture. into the stator. The slot wedges of 1.5MW and 2.5MW direct drive permanent magnet wind turbines are embedded at the same height as the iron core, and the entire surface of the stator iron core is equivalent to the outer surface of the cylinder. However, due to the design of the 2MW direct-drive permanent magnet wind turbine, the slot wedge embedded in the iron core is ...
