4, technical attributes
four.one By including a “Γ”-formed damping ring to the strong magnetic poles, the motor can supply a large adequate starting up torque, a pulling torque and a lower beginning current, which can guarantee the sleek commencing and acceleration of the motor, and have a tiny influence on the power grid, and meet the person load demands .
4.two The use of new insulating resources and insulation engineering, with super robust insulation and voltage resistance.
four.3 The motor adopts course F insulation, and the temperature increase is assessed according to the temperature increase limit value of course B insulation. It has a lengthy support life and a very good air flow technique, which tends to make the device underneath various working situations such as startup, overload, overexcitation, underexcitation, and shutdown. Make sure that the temperature increase of each and every element does not exceed the allowable restrict.
4.four Via accurate calculation and analysis, the framework of the rotor is decided. The large-electricity motor adopts the built-in construction technology of shaft and choke to make the motor secure and trustworthy.
4.5 The safety gadget is innovative and comprehensive.
4.five.1 The stator windings and bearings are geared up with temperature detection devices, which can detect, alarm and excursion.
4.five.two Shutdown place heater with anti-condensation effect.
Five, composition type
5.one The framework of this sequence of motors is typically horizontal, and the cooling approach is a closed circulating air cooling system, which is positioned at the bottom of the motor. For added-substantial-energy motors, it is of box-kind structure and water-cooled.
5.two The motor magnetic substance adopts high-quality cold-rolled silicon steel sheet with substantial magnetic permeability and lower loss, which improves the doing work efficiency of the motor and minimizes the functioning price of the motor. Rigid stator framework, the iron main is fixed on the supporting ribs of the body in the circumferential course through the dovetail groove and compressed in sections with high strain, and all the forces are transmitted to the base by way of the body, minimizing vibration. The damping ring and the magnetic pole undertake a specific correcting technique to stop malfunctions brought on 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 make certain firmness and dependability.
5.3 The stator winding is handled with VPI as a entire dipping paint, which has large electrical efficiency, mechanical energy, insulation efficiency, moisture resistance and thermal stability.
five.four The bearing is a sliding bearing with force oil circulation, which is set up in a bearing seat manufactured of solid metal. The sliding bearing has a spherical bearing that can immediately change the centre. The inner surface of the bearing is coated with a layer of Babbitt alloy to prevent energy technology Direct-tin eutectic happens when the equipment is operating at higher temperature. The bearings are insulated to avert shaft currents.
6. Conditions of Use
six.one Voltage fluctuation: ±5% (It can operate at ±10% underneath the issue of 7.three in GB755).
six.two Frequency fluctuation: ±2%.
six.three The altitude does not exceed 5000m
6.four The optimum ambient air temperature does not exceed +50ºC,
6.five The inlet temperature of the cooling drinking water of the air cooler should be held in the range of six~33ºC, the strain of the cooling water is .3Mpa, and the cooling h2o must have no corrosion effect on copper and iron.
six.six If the above fundamental situations of use are exceeded, corresponding measures or special orders need to be taken.
