Four, technological characteristics
4.1 By incorporating a “Γ”-shaped damping ring to the reliable magnetic poles, the motor can supply a big sufficient starting torque, a pulling torque and a decrease starting up existing, which can make sure the clean starting up and acceleration of the motor, and have a tiny influence on the electricity grid, and meet the consumer load specifications .
4.2 The use of new insulating resources and insulation technologies, with super powerful insulation and voltage resistance.
4.three The motor adopts class F insulation, and the temperature increase is assessed in accordance to the temperature increase limit price of class B insulation. It has a lengthy provider existence and a very good ventilation system, which makes the device beneath a variety of doing work problems this sort of as startup, overload, overexcitation, underexcitation, and shutdown. Guarantee that the temperature increase of each and every portion does not exceed the allowable limit.
four.four By way of accurate calculation and investigation, the construction of the rotor is established. The large-electricity motor adopts the integrated structure technology of shaft and choke to make the motor safe and trustworthy.
4.5 The defense unit is superior and total.
4.five.one The stator windings and bearings are equipped with temperature detection gadgets, which can detect, alarm and journey.
four.5.two Shutdown place heater with anti-condensation result.
5, construction type
5.one The composition of this collection of motors is usually horizontal, and the cooling technique is a shut circulating air cooling system, which is found at the bottom of the motor. For added-high-energy motors, it is of box-kind construction and drinking water-cooled.
5.two The motor magnetic materials adopts high-high quality cold-rolled silicon steel sheet with substantial magnetic permeability and low reduction, which improves the functioning performance of the motor and lowers the functioning cost of the motor. Rigid stator structure, 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 pressure, and all the forces are transmitted to the foundation by means of the frame, reducing vibration. The damping ring and the magnetic pole adopt a unique fixing approach to prevent malfunctions caused by inadequate make contact with all inside conductive human body connectors, fasteners, supports and screws on the rotating entire body have anti-loosening actions to make sure firmness and reliability.
5.3 The stator winding is dealt with with VPI as a entire dipping paint, which has higher electrical efficiency, mechanical toughness, insulation functionality, moisture resistance and thermal security.
5.4 The bearing is a sliding bearing with pressure oil circulation, which is set up in a bearing seat created of cast metal. The sliding bearing has a spherical bearing that can instantly adjust the heart. The interior surface of the bearing is coated with a layer of Babbitt alloy to avert energy era Lead-tin eutectic takes place when the device is managing at higher temperature. The bearings are insulated to stop shaft currents.
6. Problems of Use
six.1 Voltage fluctuation: ±5% (It can run at ±10% under the issue of 7.3 in GB755).
six.2 Frequency fluctuation: ±2%.
six.3 The altitude does not exceed 5000m
six.four The optimum ambient air temperature does not exceed +50ºC,
6.5 The inlet temperature of the cooling h2o of the air cooler ought to be held in the variety of six~33ºC, the strain of the cooling drinking water is .3Mpa, and the cooling water need to have no corrosion impact on copper and iron.
6.6 If the above simple circumstances of use are exceeded, corresponding steps or particular orders have to be taken.
