Four, complex characteristics
4.one By incorporating a “Γ”-formed damping ring to the strong magnetic poles, the motor can provide a huge enough beginning torque, a pulling torque and a reduce beginning recent, which can guarantee the easy commencing and acceleration of the motor, and have a little influence on the power grid, and meet the consumer load specifications .
4.2 The use of new insulating resources and insulation engineering, 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 increase restrict benefit of course B insulation. It has a long services daily life and a good air flow method, which tends to make the device underneath numerous operating problems such as startup, overload, overexcitation, underexcitation, and shutdown. Guarantee that the temperature increase of every component does not exceed the allowable restrict.
4.four By way of exact calculation and evaluation, the composition of the rotor is established. The high-energy motor adopts the built-in construction technology of shaft and choke to make the motor safe and dependable.
4.five The safety gadget is advanced and total.
4.five.one The stator windings and bearings are outfitted with temperature detection devices, which can detect, alarm and vacation.
four.5.two Shutdown space heater with anti-condensation result.
Five, framework type
five.one The composition of this sequence of motors is usually horizontal, and the cooling approach is a closed circulating air cooling program, which is positioned at the bottom of the motor. For added-higher-energy motors, it is of box-sort composition and water-cooled.
five.2 The motor magnetic material adopts high-quality chilly-rolled silicon steel sheet with substantial magnetic permeability and minimal reduction, which improves the functioning efficiency of the motor and reduces the working expense of the motor. Rigid stator construction, the iron core is set on the supporting ribs of the frame in the circumferential route by means of the dovetail groove and compressed in sections with substantial strain, and all the forces are transmitted to the base through the frame, minimizing vibration. The damping ring and the magnetic pole adopt a unique fixing method to stop malfunctions triggered by bad make contact with all internal conductive human body connectors, fasteners, supports and screws on the rotating entire body have anti-loosening actions to make certain firmness and dependability.
5.three The stator winding is taken care of with VPI as a complete dipping paint, which has higher electrical functionality, mechanical power, insulation functionality, dampness resistance and thermal stability.
5.four The bearing is a sliding bearing with pressure oil circulation, which is put in in a bearing seat created of forged metal. The sliding bearing has a spherical bearing that can routinely change the center. The interior surface of the bearing is coated with a layer of Babbitt alloy to stop electricity generation Guide-tin eutectic occurs when the machine is operating at large temperature. The bearings are insulated to avert shaft currents.
6. Situations of Use
6.one Voltage fluctuation: ±5% (It can operate at ±10% underneath the issue of seven.3 in GB755).
six.two Frequency fluctuation: ±2%.
six.3 The altitude does not exceed 5000m
6.four The maximum ambient air temperature does not exceed +50ºC,
6.5 The inlet temperature of the cooling h2o of the air cooler ought to be stored within the assortment of six~33ºC, the strain of the cooling drinking water is .3Mpa, and the cooling drinking water need to have no corrosion impact on copper and iron.
six.six If the above fundamental situations of use are exceeded, corresponding steps or specific orders must be taken.
