Insulating structure for 2MW wind driven generator

Abstract

The invention discloses an insulating structure for a 2MW wind driven generator. The insulating structure comprises a stator iron core, a rotor iron core, stator coils (3) embedded in the stator iron core, rotor coils (5) embedded in the rotor iron core, a mica tape coated and wound on the stator coils (3), nickel hydrazine nitrate (NHN) insulation (1) and a mica tap coated and wound on the rotor coils (5); inter-turn pads (4) are arranged among the stator coils (3); the stator iron core, the stator coils (3), the mica taps and the NHN insulation (1) are bonded together through solvent-free impregnated resin and vacuum pressure impregnation; and the rotor iron core, the rotor coils (5) and the mica tapes are bonded together through the solvent-free impregnated resin and the vacuum pressure impregnation. The invention has the advantages that: the electromechanical properties of the insulating structure can be improved, the aging speed of the insulating structure is slowed down, the service life of the insulating structure is long, the production cost is greatly reduced, and the problem of inter-turn insulation impact caused by a frequency converter is solved.

Description

technical field [0001] The invention relates to an insulating structure, in particular to an insulating structure of a 2MW wind power generator. Background technique [0002] The motor insulation structure is one of the most important components of the motor. The motor insulation structure mainly plays the role of isolating the electromotive force in the motor, making the current flow along the specified direction, and also has the function of fixing the winding; at the same time, the motor insulation structure is also the motor The component with the most concentrated stress and the weakest strength is affected by temperature, electric field, environmental conditions and mechanical stress at the same time. Therefore, the reliability and stability of the motor insulation structure performance is often the key factor that determines the reliability and service life of the motor. [0003] As a clean and renewable energy, wind energy has been paid more and more attention by peo...
