Description
Technical field
The utility model relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), is specifically related to a kind of radial ventilation generator core.
Background technology
The Core Design of existing radial ventilation generator is the radial ducts of equal length, but internal heat dissipating situation reality unshakable in one's determination is divided into two ends unshakable in one's determination temperature lower substantially, higher in the middle of unshakable in one's determination.Traditional stator and rotor Core Design does not consider this kind of situation, and the result caused is for motor two ends, and cooling power is excessive, but less than normal again for the position cooling power that medium temperature unshakable in one's determination is higher.If choose electrical machine insulation grade according to temperature highest point unshakable in one's determination, production procurement high cost can be made, if choose electrical machine insulation grade by mean temperature, then the electrical machine insulation life-span is too short, the utility model then makes whole Temperature Distribution unshakable in one's determination more consistent, effectively determines temperature rise unshakable in one's determination, reduces costs.
Utility model content
The purpose of this utility model is to provide a kind of radial ventilation generator core, and solving existing Core Design is that the radial ducts of equal length causes motor two ends cooling power excessive, and the problem that the higher position cooling power of medium temperature unshakable in one's determination is less than normal again.
The technical scheme that the utility model adopts is, a kind of radial ventilation generator core, comprise the stator be enclosed within generator pit and the rotor be enclosed within alternator shaft, stator comprises stator core and stator tooth compressing tablet, stator core is divided into multiple stator core segment by stator tooth compressing tablet, and the length of each stator core segment is different, and rotor comprises rotor core and rotor tooth compressing tablet, rotor core is divided into multiple rotor core section by rotor tooth compressing tablet, and the length of each rotor core section is different.
Feature of the present utility model is also,
Each corresponding stator core segment is identical with the length of rotor core section.
The shortest stator core segment and rotor core section are positioned at 2/3 place to the right, stator core center.
The beneficial effects of the utility model are, the utility model radial ventilation generator core, according to the actual conditions of stator core variations in temperature, by constant for radial ventilation width, stator core segment and rotor core section are designed to pattern different in size, the cooling power effectively utilizing rotor to produce, rationally cools motor, thus reduces electric machine temperature rise by most reasonable manner.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model radial ventilation generator core.
In figure, 1. support, 2. stator tooth compressing tablet, 3. stator core segment, 4. rotor core section, 5. rotor tooth compressing tablet, 6. rotating shaft.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of radial ventilation generator core of the utility model, as shown in Figure 1, comprise the stator be enclosed within generator pit 1 and the rotor be enclosed within alternator shaft 6, stator comprises stator core and stator tooth compressing tablet 2, stator core is divided into multiple stator core segment 3 by stator tooth compressing tablet 2, the length of each stator core segment 3 is different, the position that axial distribution temperature is high, radial ducts quantity is many, the position that axial distribution temperature is lower, radial ducts quantity is few, rotor comprises rotor core and rotor tooth compressing tablet 5, rotor core is divided into multiple rotor core section 4 by rotor tooth compressing tablet 5, the length of each rotor core section 4 is different, corresponding with stator core air channel.
Each corresponding stator core segment 3 is identical with the length of rotor core section 4.
The shortest stator core segment 3 and rotor core section 4 are positioned at 2/3 place to the right, stator core center.
The principle of the utility model radial ventilation generator core: by the mensuration to electric machine iron core Temperature Distribution, reasonable arrangement stack of lamination length: for motor air intake, air inlet coolant temperature is lower, rationally increase stack of lamination width herein, and air outlet position coolant temperature is higher, than air inlet stack of lamination width, rationally interferric width can be reduced herein.2/3 place to the right at the center of iron core is whole temperature highest point unshakable in one's determination, core length is the shortest herein, distributed maximum radial ventilation grooves, increase ventilating and cooling efficiency herein, the temperature of effective reduction temperature higher position iron core, thus make the temperature value of whole iron core more balanced, effectively reduce the temperature unshakable in one's determination of temperature highest point.
The utility model radial ventilation generator core, according to the actual conditions of stator core variations in temperature, by constant for radial ventilation width, stator core segment and rotor core section are designed to pattern different in size, effectively utilize the cooling power that rotor produces, rationally motor is cooled, thus reduce electric machine temperature rise by most reasonable manner.
