Four, specialized characteristics
four.1 By incorporating a “Γ”-formed damping ring to the reliable magnetic poles, the motor can provide a big sufficient starting up torque, a pulling torque and a reduce starting recent, which can guarantee the clean commencing and acceleration of the motor, and have a small affect on the electrical power grid, and meet up with the user load needs .
four.2 The use of new insulating supplies and insulation engineering, with super powerful insulation and voltage resistance.
four.3 The motor adopts class F insulation, and the temperature rise is assessed in accordance to the temperature rise limit price of class B insulation. It has a lengthy services existence and a good ventilation technique, which tends to make the device below different doing work circumstances such as startup, overload, overexcitation, underexcitation, and shutdown. Guarantee that the temperature increase of each element does not exceed the allowable limit.
four.4 Via precise calculation and evaluation, the composition of the rotor is determined. The higher-power motor adopts the integrated construction technologies of shaft and choke to make the motor secure and trustworthy.
4.five The security system is advanced and total.
four.five.1 The stator windings and bearings are geared up with temperature detection units, which can detect, alarm and excursion.
four.five.two Shutdown space heater with anti-condensation influence.
5, composition sort
five.1 The construction of this series of motors is usually horizontal, and the cooling method is a closed circulating air cooling program, which is positioned at the base of the motor. For additional-large-energy motors, it is of box-sort structure and h2o-cooled.
5.two The motor magnetic materials adopts substantial-quality cold-rolled silicon steel sheet with substantial magnetic permeability and minimal decline, which improves the functioning performance of the motor and minimizes the working expense of the motor. Rigid stator composition, the iron main is mounted on the supporting ribs of the body in the circumferential route 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 adopt a particular correcting approach to stop malfunctions brought on by poor speak to all internal conductive entire body connectors, fasteners, supports and screws on the rotating entire body have anti-loosening steps to guarantee firmness and trustworthiness.
5.three The stator winding is treated with VPI as a entire dipping paint, which has substantial electrical performance, mechanical toughness, insulation functionality, dampness resistance and thermal stability.
5.four The bearing is a sliding bearing with pressure oil circulation, which is set up in a bearing seat manufactured of forged metal. The sliding bearing has a spherical bearing that can immediately modify the center. The inner floor 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 stop shaft currents.
six. Situations of Use
6.1 Voltage fluctuation: ±5% (It can run at ±10% underneath the condition of 7.three in GB755).
six.two Frequency fluctuation: ±2%.
six.three 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 stored inside the variety of six~33ºC, the pressure of the cooling water is .3Mpa, and the cooling drinking water ought to have no corrosion effect on copper and iron.
6.six If the previously mentioned simple conditions of use are exceeded, corresponding steps or unique orders should be taken.
