Description
Technical field
The present invention relates to the steam turbine generator with the two-way water-cooled end cooling system of spiral, belong to machine field.
Background technology
Large turbo-type generator single-machine capacity and electromagnetic load are larger, in addition generator end region inner structure and leakage field
Field distribution is complex, cause generator end component copper shield, pressure to refer to, the magnetic of trim ring and stator end core it is close higher.Peace
Copper shield outside generator end component trim ring can effectively resist the leakage field of end regions, and then reduce copper shield
Other end member magnetic below are close.Because copper shield eddy-current loss is big, thickness of thin, small volume so that copper shield it is hot it is close very
Height, and then cause the heating of end member copper shield very serious, equally, the end member trim ring in the presence of brow leakage field
Temperature is also higher.
In order to solve the problems, such as that copper shield and trim ring temperature are too high, air duct is left between copper shield and trim ring, is divulged information
Cooling fluid serves the effect for reducing copper shield and trim ring temperature in ditch, however, only with this single ventilating and cooling
Structure is difficult to be effectively reduced copper shield and the temperature of trim ring, particularly when steam turbine generator leading phase operation, copper shield and pressure
Cooling fluid can not effectively take away the heat of more end members in air duct between circle, cause end member copper shield and pressure
The temperature of circle significantly raises, and irrational end ventilating and cooling design can influence the service life of generator.Turbine generator generator terminal
Portion region can use it is a kind of it is new have the two-way water-cooled end cooling system of spiral, can be with by the two-way cooling water of spiral
Effectively take away the heat of generate heat serious copper shield and trim ring, it will be apparent that reduce end member copper shield and the highest temperature of trim ring
Degree, it is ensured that the temperature rise of end member is limited in allowed band.
The content of the invention
It is an object of the invention to provide the steam turbine generator with the two-way water-cooled end cooling system of spiral, with solve by
The end member copper shield and the problem of too high trim ring temperature caused by the design of turbo-generator end zonal ventilation is unreasonable,
End member copper shield and the temperature of trim ring are significantly reduced, improves the ability that steam turbine generator is run steadily in the long term.
The present invention the steam turbine generator with the two-way water-cooled end cooling system of spiral, it including copper shield, trim ring,
Pressure refer to, stator end core, wind deflector, upside water recirculator, downside water recirculator, air duct, wind-guiding ditch, inner ring
Wound water channel, outer circulating type water channel and external application formula water annulus.Copper shield is by copper shield lower lateral section, copper shield interlude and copper
Shield upper lateral section composition.Pressure, which refers to be referred to refer to short pressure by long pressure, to be formed.Interior circulating type water channel is guided by the entrance of interior circulating type water channel
The outlets direct pipe composition of pipe, interior circulating type water channel body and interior circulating type water channel.Outer circulating type water channel is by outer circulating type water channel
Entrance guiding tube, the outlets direct pipe composition of outer circulating type water channel body and outer circulating type water channel.Copper shield is arranged on trim ring
Outside, leave air duct between copper shield and trim ring, wind deflector is arranged on the outer radius of copper shield, upside water recirculator
The upper side and lower side of wind deflector, interior circulating type water channel body and outer circulating type water channel are separately mounted to downside water recirculator
Main body is in axial direction spirally advanced, and interior circulating type water channel body and outer circulating type water channel body are installed on the downside of copper shield
Section, copper shield interlude and trim ring inner circle region, external application formula water annulus are close to the inner surface of copper shield.Interior circulating type water channel
It is opposite with the flow direction of cooling water in outer circulating type water channel.
Preferably, the entrance guiding tube of described interior circulating type water channel, interior circulating type water channel body and interior circulating type water
The outlets direct pipe in road is interconnected, the entrance guiding tube of outer circulating type water channel, outer circulating type water channel body and outer circulating type water
The outlets direct pipe in road is interconnected.Cooling water in the water recirculator of upside has respectively entered interior circulating type water channel, outer shroud
In wound water channel and external application formula water annulus downside recirculated water cooling is entered after cooled electric generator end member copper shield and trim ring
But device.The speed for entering cooling water in interior circulating type water channel, outer circulating type water channel and external application formula water annulus is 2 m/s,
The height of external application formula water annulus is 2 mm to 4 mm.The section of interior circulating type water channel and outer circulating type water channel is circle, circle
A diameter of 2 mm to 5 mm of shape.Interior circulating type water in interior circulating type water channel body and trim ring inner circle region in copper shield lower lateral section
Road main body is connected, copper shield lower lateral section China and foreign countries circulating type water channel body and trim ring inner circle region China and foreign countries circulating type water channel body phase
Connection.
