Abstract
The utility model provides a generator capable of operating in a high altitude region safely, stably and for a long time, including a stator, a rotor, a end cap and bearings. The generator is characterized in that a windings employs an insulating layer having an insulation grade of H level based on the original design structure of the conventional type generator, the top of the generator cabinet is provided with a radiator, the top of a fan guard of a fan outside the back end of the generator is provided with ventilating openings for communicating air ducts of the radiator with the outer, an outer fan is used to blast air, the freezing air is supplied to the generator through air inlets, the cold air passes through a radiator cold air tube through the fan air blast, part heat generated by the windings and the bearings of the generator during an operating process may be brought into a radiator hot air channel, the cold and the heat air exchange, thus it is capable reducing the temperature rise when the windings and the bearings of the generator are running, to improve the insulation and heat dispersion of the generator.
Description
Technical field
The utility model relates to a kind of high height above sea level type wind-driven generator, belongs to technical field of wind power generation, can be in the regional safety of 2000 meters-4000 meters of height above sea level, stable, long-time running.
Background technology
The conventional type wind-driven generator only is adapted at the area operation that height above sea level is lower than 2000 meters at present, and when be higher than 2000 meter districts at height above sea level, air pressure is low to moderate under the special climate condition of 60Kpa, and especially in the area of height above sea level up to 4000 meters, atmospheric density is 0.8kg/m
3About, temperature is minimum to reach-45 ℃, day limit temperature difference can reach 30 ℃, add dry many thunders and lightnings, strong and the wind-force of solar radiation changes and waits extreme climate all the operation of motor to be caused a series of influences greatly, for example, the electricity generator stator coil corona inception voltage is low, coil and bearing operating temperature height, and temperature rise is big, motor external insulation intensity reduces, sealing property deterioration etc., conventional motor moves under such weather conditions, and it is low to be easy to generate dielectric strength, coil and bearing temperature rise are crossed high phenomenon, very easily cause the damage of generator.
Summary of the invention
The utility model proposes a kind of high height above sea level type wind-driven generator, can solve that the electricity generator stator coil corona inception voltage is low, coil and bearing operating temperature height, temperature rise is big, motor external insulation intensity reduces and problem such as poor sealing performance, ensures safe, stable, the long-time running of generator in the high altitude localities.
The utility model comprises stator, rotor, end cap and bearing.The technical scheme that is adopted is: on the former design basis of conventional generator, it is the insulating barrier of H level that winding adopts the class of insulation, and the maximum permissible temperature of motor can reach 180 ℃ like this, and the winding temperature rise limit value is 125K; In wind generating set engine room cover space, at the top of electric generator casing configuration radiator, fan guard top at generator rearward end external fan has ventilation hole, the air channel of radiator is communicated with it, utilize external fan to carry out air blast, cold air enters in the generator by extraneous wind air inlet, passes through the fan air blast again through radiator cold wind fresh air inlet, and cold air is by the radiator cool air hose then.The part heat that the winding of generator and bearing produce in running can enter the radiator heat air channel, cold and hot air has reduced the temperature rise of generator windings and bearing by heat exchange, after the air of cold and hot exchange discharge by the hot blast air outlet of radiator and generator fuselage cover junction.
The beneficial effects of the utility model are: on the basis of other structural designs that do not change former generator type, in the generator operation process, can obviously reduce generator windings and bearing temperature rise, make it reach the designing requirement that moves under the high height above sea level condition; In addition, adopt this mode can avoid corona to occur, guarantee generator in high altitude localities safety, stable, long-time running, and this utility model have reasonable in design, characteristics such as technology is simple, and is reliable, easy to maintenance.

Embodiment
See figures.1.and.2 the utility model done an explanation:
The radiator 1 of generator is installed in the top of electric generator casing, be positioned over the upper surface of radiating ribs, cold air enters in the generator by extraneous wind air inlet 3, passes through the fan air blast again through radiator cold wind fresh air inlet 2, and cold air is by radiator cool air hose 4 then.The part heat that the winding of generator and bearing produce in running can enter radiator heat air channel 5, cold and hot air has reduced the temperature rise of generator windings and bearing by heat exchange, after the air of cold and hot exchange discharge by the hot blast air outlet 6 of radiator and generator fuselage cover junction.
