Abstract
A permanent-magnet high-speed wind-driven generator group belongs to the generating equipment. A high-speed magneto generator is fixed on the rear portion position of a step-up gear box on a chassis, the front end of a driving shaft and the rear end of the driving shaft are respectively connected with a power output shaft of the step-up gear box and a main shaft of the high-speed magneto generator, the working rotate speed of the high-speed magneto generator is 750-1200 rotating per minute, and the electricity frequency which is generated by the high-speed magneto generator is 80-180 Hertz. The generator group has the advantages of light weight, small volume, low processing difficulty, high generating efficiency and fewer faults.
Description
Technical field
The utility model belongs to power generating equipment, relates generally to a kind of wind-force high-speed permanent magnetic rotor machine.
Background technique
Along with the raising of environmental protection and energy saving consciousness, in recent years, the development of wind power plant is extremely rapid.At present, many in wind power generating set rotating speed is configured in the unit as the generating main frame at 1000-1800 rev/min asynchronous double-fed generator, because its power generation operation rotating speed height, the gear box ratio that mates in the unit is big, its requirement on machining accuracy is very high, technology difficulty is big, and processing cost is high, and fault is also more in the use, simultaneously, asynchronous double-fed generator consumes exciting power, collector ring rate of fault height, and the rotor radiating condition is poor.In addition, asynchronous double-fed generator volume and weight is bigger.
Summary of the invention
The purpose of this utility model is exactly problem and the defective that exists at above-mentioned prior art, design provides a kind of permanent magnetism high-speed wind power generator set, reaches the purpose that alleviates generator weight, reduces volume, reduces difficulty of processing, improves generating efficiency, reduces the fault point.
Basic design of the present utility model is, on support rotating speed being installed is the 750-1200 rev/min of high-speed permanent magnetic generator that the electric frequency of sending is the 80-180 hertz, this high-speed permanent magnetic generator is positioned at the step-up gear rear portion, connect the live axle front and back ends and be connected with the high-speed permanent magnetic generator shaft with the step-up gear pto respectively, so far constitute permanent magnetism high-speed wind power generator set.
The utility model is being determined on the basis with the rational structure key element, the high-speed permanent magnetic generator is mated in wind power driving system as the generating main frame, realized the high generating efficiency of wind-power electricity generation, have characteristics in light weight, that volume is little, difficulty of processing is low, generating efficiency is high, fault is few, especially be fit to the permanent magnetism high-speed wind power generator set of generated output between 1 megawatt to 5 megawatt and use.Compare the raising generating efficiency with asynchronous double-fed generator more than 14%, every increases generating income 25-30% unit year.
