4, technological characteristics
4.1 By incorporating a “Γ”-formed damping ring to the sound magnetic poles, the motor can supply a huge sufficient beginning torque, a pulling torque and a reduced beginning current, which can guarantee the clean commencing and acceleration of the motor, and have a tiny impact on the power grid, and meet the user load needs .
four.two The use of new insulating materials and insulation technological innovation, with super powerful insulation and voltage resistance.
4.3 The motor adopts class F insulation, and the temperature rise is assessed according to the temperature increase restrict price of class B insulation. It has a long provider existence and a very good ventilation program, which tends to make the device under various doing work conditions these kinds of as startup, overload, overexcitation, underexcitation, and shutdown. Make certain that the temperature increase of each and every component does not exceed the allowable limit.
4.four Via precise calculation and investigation, the framework of the rotor is determined. The large-energy motor adopts the built-in construction technological innovation of shaft and choke to make the motor secure and reliable.
four.five The defense system is superior and comprehensive.
4.5.one The stator windings and bearings are equipped with temperature detection products, which can detect, alarm and journey.
four.5.2 Shutdown room heater with anti-condensation impact.
Five, structure kind
5.1 The structure of this collection of motors is generally horizontal, and the cooling technique is a closed circulating air cooling technique, which is situated at the base of the motor. For additional-higher-energy motors, it is of box-sort construction and h2o-cooled.
five.two The motor magnetic substance adopts substantial-high quality chilly-rolled silicon steel sheet with higher magnetic permeability and low reduction, which increases the functioning performance of the motor and reduces the working cost of the motor. Rigid stator composition, the iron main is fastened on the supporting ribs of the frame in the circumferential course by means of the dovetail groove and compressed in sections with large pressure, and all the forces are transmitted to the base by way of the body, minimizing vibration. The damping ring and the magnetic pole adopt a particular correcting approach to avert malfunctions triggered by very poor contact all inside conductive entire body connectors, fasteners, supports and screws on the rotating entire body have anti-loosening measures to ensure firmness and dependability.
five.three The stator winding is taken care of with VPI as a complete dipping paint, which has high electrical overall performance, mechanical power, insulation functionality, dampness resistance and thermal stability.
five.4 The bearing is a sliding bearing with stress oil circulation, which is put in in a bearing seat manufactured of forged metal. The sliding bearing has a spherical bearing that can immediately alter the center. The internal surface of the bearing is coated with a layer of Babbitt alloy to prevent electricity era Lead-tin eutectic occurs when the machine is managing at high temperature. The bearings are insulated to prevent shaft currents.
6. Problems of Use
6.1 Voltage fluctuation: ±5% (It can operate at ±10% under the situation of 7.3 in GB755).
six.two Frequency fluctuation: ±2%.
six.3 The altitude does not exceed 5000m
6.4 The highest ambient air temperature does not exceed +50ºC,
6.5 The inlet temperature of the cooling h2o of the air cooler should be kept in the variety of six~33ºC, the stress of the cooling drinking water is .3Mpa, and the cooling drinking water need to have no corrosion influence on copper and iron.
6.6 If the over simple problems of use are exceeded, corresponding measures or particular orders should be taken.
