4, specialized characteristics
four.one By including a “Γ”-shaped damping ring to the reliable magnetic poles, the motor can provide a large ample starting up torque, a pulling torque and a lower commencing recent, which can make certain the easy commencing and acceleration of the motor, and have a modest influence on the electrical power grid, and meet the person load specifications .
4.2 The use of new insulating supplies and insulation technological innovation, with tremendous strong insulation and voltage resistance.
four.three The motor adopts course F insulation, and the temperature rise is assessed in accordance to the temperature rise limit benefit of class B insulation. It has a long service life and a excellent ventilation technique, which makes the unit under various operating problems this sort of as startup, overload, overexcitation, underexcitation, and shutdown. Ensure that the temperature rise of every single component does not exceed the allowable restrict.
4.four By means of accurate calculation and investigation, the framework of the rotor is identified. The large-energy motor adopts the built-in structure technologies of shaft and choke to make the motor protected and reliable.
four.5 The safety device is sophisticated and total.
four.five.one The stator windings and bearings are equipped with temperature detection units, which can detect, alarm and vacation.
four.5.2 Shutdown place heater with anti-condensation effect.
5, construction type
five.1 The framework of this collection of motors is normally horizontal, and the cooling approach is a closed circulating air cooling system, which is positioned at the bottom of the motor. For further-higher-power motors, it is of box-sort composition and h2o-cooled.
5.two The motor magnetic substance adopts higher-high quality chilly-rolled silicon steel sheet with large magnetic permeability and minimal loss, which enhances the functioning performance of the motor and lowers the operating price of the motor. Rigid stator composition, the iron main is fixed on the supporting ribs of the frame in the circumferential direction through the dovetail groove and compressed in sections with large strain, and all the forces are transmitted to the base through the frame, minimizing vibration. The damping ring and the magnetic pole undertake a special fixing method to stop malfunctions induced by bad get in touch with all interior conductive physique connectors, fasteners, supports and screws on the rotating entire body have anti-loosening measures to guarantee firmness and dependability.
five.three The stator winding is taken care of with VPI as a whole dipping paint, which has large electrical overall performance, mechanical toughness, insulation functionality, moisture resistance and thermal balance.
five.4 The bearing is a sliding bearing with pressure oil circulation, which is installed in a bearing seat created of forged steel. The sliding bearing has a spherical bearing that can immediately adjust the center. The inner floor of the bearing is coated with a layer of Babbitt alloy to avert electrical power era Lead-tin eutectic takes place when the equipment is running at large temperature. The bearings are insulated to avert shaft currents.
six. Situations of Use
six.1 Voltage fluctuation: ±5% (It can operate at ±10% under the issue of seven.3 in GB755).
six.two Frequency fluctuation: ±2%.
6.3 The altitude does not exceed 5000m
six.4 The highest ambient air temperature does not exceed +50ºC,
six.five The inlet temperature of the cooling water of the air cooler must be kept in the assortment of six~33ºC, the force of the cooling h2o is .3Mpa, and the cooling h2o ought to have no corrosion effect on copper and iron.
6.6 If the previously mentioned fundamental conditions of use are exceeded, corresponding actions or unique orders must be taken.
