4, technological qualities
4.one By introducing a “Γ”-formed damping ring to the solid magnetic poles, the motor can offer a large enough beginning torque, a pulling torque and a reduce starting up recent, which can make sure the sleek starting and acceleration of the motor, and have a little effect on the electricity grid, and satisfy the person load requirements .
4.2 The use of new insulating resources and insulation technologies, with super powerful insulation and voltage resistance.
four.three The motor adopts class F insulation, and the temperature increase is assessed in accordance to the temperature increase limit price of class B insulation. It has a long services life and a great air flow program, which tends to make the unit below a variety of working situations this sort of as startup, overload, overexcitation, underexcitation, and shutdown. Make certain that the temperature increase of each and every element does not exceed the allowable restrict.
4.4 By means of correct calculation and analysis, the structure of the rotor is decided. The large-electrical power motor adopts the built-in structure engineering of shaft and choke to make the motor risk-free and reputable.
4.five The security system is advanced and full.
four.5.one The stator windings and bearings are outfitted with temperature detection devices, which can detect, alarm and excursion.
four.five.two Shutdown space heater with anti-condensation effect.
Five, composition kind
5.1 The composition of this sequence of motors is typically horizontal, and the cooling technique is a shut circulating air cooling program, which is positioned at the bottom of the motor. For added-substantial-electrical power motors, it is of box-variety structure and drinking water-cooled.
5.two The motor magnetic material adopts higher-top quality chilly-rolled silicon metal sheet with large magnetic permeability and reduced decline, which enhances the working performance of the motor and decreases the running price of the motor. Rigid stator construction, the iron main is fastened on the supporting ribs of the body in the circumferential route via the dovetail groove and compressed in sections with higher stress, and all the forces are transmitted to the foundation via the body, reducing vibration. The damping ring and the magnetic pole adopt a unique fixing technique to avert malfunctions triggered by very poor contact all inner conductive entire body connectors, fasteners, supports and screws on the rotating body have anti-loosening measures to make sure firmness and reliability.
5.three The stator winding is taken care of with VPI as a entire dipping paint, which has substantial electrical functionality, mechanical strength, insulation overall performance, moisture resistance and thermal security.
five.4 The bearing is a sliding bearing with pressure oil circulation, which is put in in a bearing seat created of solid steel. The sliding bearing has a spherical bearing that can automatically modify the middle. The internal surface area of the bearing is coated with a layer of Babbitt alloy to avoid energy generation Direct-tin eutectic takes place when the device is working at high temperature. The bearings are insulated to avoid shaft currents.
6. Conditions of Use
6.one Voltage fluctuation: ±5% (It can run at ±10% beneath the condition of 7.three in GB755).
six.two Frequency fluctuation: ±2%.
six.3 The altitude does not exceed 5000m
6.four The highest ambient air temperature does not exceed +50ºC,
6.5 The inlet temperature of the cooling h2o of the air cooler must be kept inside of the selection of 6~33ºC, the force of the cooling water is .3Mpa, and the cooling water ought to have no corrosion impact on copper and iron.
six.six If the earlier mentioned standard situations of use are exceeded, corresponding measures or special orders should be taken.
