Wind turbine alternator YJ258A

three-phaseasynchronous4-pole

2MW air-cooling double-fed asynchronous wind power generator (4 poles) adopts unique radical ventilation structure, and its product temperature rise is significantly lower than national standard; Its stator and rotor windings adopt Class-H corona-resistant insulation structure and vacuum pressure impregnation, which enable it operate continuously in complex conditions with good insulation performance and high reliability; The rotor is all under dynamic balance in the whole speed range, and its precision grade reaches G1.0. The vibration and noise limit of the entire machine is significantly lower than national standard. Applicable environment: Inland, plateau (elevation≤3000m) and low wind-speed conditions, etc.
