Product Description

 

Product Description

        The 5MW air-cooled doubly-fed wind turbine is the largest doubly-fed wind turbine in China. It adopts radial ventilated air-water cooling structure, box-type seat, three-bearing support, and IP54 protection level of the body; it adopts H-class insulation structure, stator and rotor winding vacuum pressure dipping paint and rotating baking treatment, which makes the generator overall insulation performance excellent and reliable, with high mechanical and electrical strength; the rotor adopts special corona-resistant insulating structure, which has a strong ability of resisting harmonic impacts of frequency converter.

Main technical features

        1.Adopting symmetrical radial ventilated air and water cooling structure design, the temperature distribution of motor winding is uniform, which effectively prolongs the service life of insulation system;
        2.The symmetrical cooling circuit structure makes the temperature rise of the bearings at both ends smaller, and improves the reliability of bearing operation;
        3.The adoption of 6300V stator output voltage effectively reduces the stator current and the cost of other parts of the machine, which is conducive to controlling the cost of the unit;
        4.The air-water cooler adopts a horizontal heat exchanger structure, which effectively reduces the height and volume of the whole machine;
        5.The cooler adopts no heat exchanger fan design, avoiding the downtime loss caused by cooling motor failure.
