Four, complex qualities
four.one By adding a “Γ”-shaped damping ring to the sound magnetic poles, the motor can provide a large ample commencing torque, a pulling torque and a decrease starting existing, which can make certain the easy starting and acceleration of the motor, and have a small impact on the electricity grid, and satisfy the person load requirements .
four.two The use of new insulating supplies and insulation technology, with tremendous powerful insulation and voltage resistance.
four.three The motor adopts course F insulation, and the temperature increase is assessed in accordance to the temperature increase restrict price of class B insulation. It has a extended service lifestyle and a great air flow technique, which can make the unit under a variety of functioning circumstances this kind of as startup, overload, overexcitation, underexcitation, and shutdown. Make certain that the temperature rise of each and every part does not exceed the allowable restrict.
four.4 By means of correct calculation and analysis, the composition of the rotor is established. The high-power motor adopts the integrated composition technology of shaft and choke to make the motor safe and reliable.
four.5 The safety gadget is superior and comprehensive.
4.five.1 The stator windings and bearings are equipped with temperature detection gadgets, which can detect, alarm and excursion.
four.5.2 Shutdown space heater with anti-condensation result.
5, construction type
5.1 The composition of this sequence of motors is generally horizontal, and the cooling approach is a closed circulating air cooling technique, which is situated at the base of the motor. For further-substantial-electrical power motors, it is of box-type structure and water-cooled.
five.two The motor magnetic materials adopts large-high quality cold-rolled silicon metal sheet with substantial magnetic permeability and low loss, which improves the operating performance of the motor and minimizes the operating expense of the motor. Rigid stator composition, the iron core is fixed on the supporting ribs of the body in the circumferential path via the dovetail groove and compressed in sections with high pressure, and all the forces are transmitted to the base through the body, reducing vibration. The damping ring and the magnetic pole undertake a special fixing method to stop malfunctions induced by poor get in touch with all inner conductive human body connectors, fasteners, supports and screws on the rotating body have anti-loosening actions to guarantee firmness and reliability.
5.3 The stator winding is dealt with with VPI as a entire dipping paint, which has high electrical functionality, mechanical power, insulation functionality, dampness resistance and thermal steadiness.
5.four The bearing is a sliding bearing with pressure oil circulation, which is mounted in a bearing seat made of forged steel. The sliding bearing has a spherical bearing that can automatically alter the heart. The interior floor of the bearing is coated with a layer of Babbitt alloy to stop power generation Direct-tin eutectic happens when the equipment is working at substantial temperature. The bearings are insulated to prevent shaft currents.
6. Problems of Use
6.1 Voltage fluctuation: ±5% (It can run at ±10% under the condition of 7.3 in GB755).
6.2 Frequency fluctuation: ±2%.
six.3 The altitude does not exceed 5000m
six.four The greatest ambient air temperature does not exceed +50ºC,
six.five The inlet temperature of the cooling h2o of the air cooler ought to be stored in the variety of 6~33ºC, the force of the cooling h2o is .3Mpa, and the cooling water need to have no corrosion effect on copper and iron.
six.six If the previously mentioned basic conditions of use are exceeded, corresponding measures or special orders have to be taken.
