4, complex qualities
four.one By incorporating a “Γ”-shaped damping ring to the strong magnetic poles, the motor can provide a large sufficient commencing torque, a pulling torque and a reduced starting present, which can guarantee the easy commencing and acceleration of the motor, and have a small affect on the electricity grid, and meet the user load demands .
four.2 The use of new insulating resources and insulation technology, with super powerful insulation and voltage resistance.
four.3 The motor adopts course F insulation, and the temperature rise is assessed according to the temperature rise restrict value of course B insulation. It has a prolonged services daily life and a very good air flow program, which can make the unit underneath various doing work situations these kinds of as startup, overload, overexcitation, underexcitation, and shutdown. Ensure that the temperature increase of each and every component does not exceed the allowable limit.
four.4 Via exact calculation and investigation, the composition of the rotor is determined. The high-power motor adopts the built-in structure technology of shaft and choke to make the motor protected and trustworthy.
four.5 The defense system is superior and total.
4.5.one The stator windings and bearings are outfitted with temperature detection units, which can detect, alarm and excursion.
four.5.two Shutdown area heater with anti-condensation influence.
5, framework sort
five.one The composition of this sequence of motors is normally horizontal, and the cooling strategy is a shut circulating air cooling technique, which is positioned at the bottom of the motor. For extra-substantial-power motors, it is of box-variety construction and drinking water-cooled.
5.2 The motor magnetic substance adopts large-high quality cold-rolled silicon metal sheet with large magnetic permeability and low loss, which enhances the doing work effectiveness of the motor and minimizes the working cost of the motor. Rigid stator framework, the iron core is fixed on the supporting ribs of the frame in the circumferential course via the dovetail groove and compressed in sections with large pressure, and all the forces are transmitted to the foundation by means of the frame, reducing vibration. The damping ring and the magnetic pole undertake a unique correcting technique to prevent malfunctions caused by poor get in touch with all inner conductive body connectors, fasteners, supports and screws on the rotating body have anti-loosening steps to ensure firmness and trustworthiness.
five.3 The stator winding is dealt with with VPI as a entire dipping paint, which has large electrical efficiency, mechanical energy, insulation overall performance, humidity resistance and thermal security.
5.4 The bearing is a sliding bearing with strain oil circulation, which is put in in a bearing seat manufactured of cast steel. The sliding bearing has a spherical bearing that can routinely modify the centre. The interior floor of the bearing is coated with a layer of Babbitt alloy to prevent power era Direct-tin eutectic happens when the equipment is managing at higher temperature. The bearings are insulated to prevent shaft currents.
6. Problems of Use
six.1 Voltage fluctuation: ±5% (It can run at ±10% under the problem of seven.three in GB755).
six.2 Frequency fluctuation: ±2%.
six.three The altitude does not exceed 5000m
six.4 The greatest ambient air temperature does not exceed +50ºC,
6.five The inlet temperature of the cooling drinking water of the air cooler ought to be held within the range of 6~33ºC, the force of the cooling water is .3Mpa, and the cooling h2o should have no corrosion impact on copper and iron.
six.6 If the previously mentioned basic problems of use are exceeded, corresponding steps or special orders must be taken.
