Four, technical qualities
4.one By incorporating a “Γ”-formed damping ring to the solid magnetic poles, the motor can give a huge sufficient starting up torque, a pulling torque and a reduce starting recent, which can guarantee the smooth starting up and acceleration of the motor, and have a modest impact on the energy grid, and meet up with the person load demands .
four.two The use of new insulating resources and insulation engineering, with super powerful insulation and voltage resistance.
four.three The motor adopts course 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 very good air flow program, which tends to make the unit beneath numerous working situations such as startup, overload, overexcitation, underexcitation, and shutdown. Make sure that the temperature rise of every single element does not exceed the allowable limit.
four.4 Through accurate calculation and analysis, the construction of the rotor is established. The large-electrical power motor adopts the integrated structure technologies of shaft and choke to make the motor risk-free and reliable.
four.five The security system is innovative and complete.
4.5.1 The stator windings and bearings are equipped with temperature detection products, which can detect, alarm and journey.
4.five.2 Shutdown room heater with anti-condensation impact.
5, composition sort
5.1 The composition of this sequence of motors is normally horizontal, and the cooling method is a closed circulating air cooling technique, which is found at the base of the motor. For further-high-electricity motors, it is of box-kind framework and h2o-cooled.
five.two The motor magnetic material adopts substantial-quality cold-rolled silicon metal sheet with large magnetic permeability and low loss, which increases the functioning performance of the motor and reduces the functioning cost of the motor. Rigid stator structure, the iron core is fixed on the supporting ribs of the frame in the circumferential course via the dovetail groove and compressed in sections with high pressure, and all the forces are transmitted to the foundation through the frame, minimizing vibration. The damping ring and the magnetic pole undertake a particular correcting method to prevent malfunctions triggered by poor make contact with all inside conductive human body connectors, fasteners, supports and screws on the rotating human body have anti-loosening actions to make certain firmness and reliability.
5.3 The stator winding is treated with VPI as a whole dipping paint, which has high electrical overall performance, mechanical energy, insulation efficiency, moisture resistance and thermal stability.
5.four The bearing is a sliding bearing with strain oil circulation, which is mounted in a bearing seat produced of forged steel. The sliding bearing has a spherical bearing that can routinely modify the centre. The inner floor of the bearing is coated with a layer of Babbitt alloy to prevent power technology Lead-tin eutectic happens when the equipment is managing at higher temperature. The bearings are insulated to avert shaft currents.
6. Conditions of Use
six.1 Voltage fluctuation: ±5% (It can operate at ±10% under the condition of seven.3 in GB755).
6.two Frequency fluctuation: ±2%.
6.3 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 must be stored in the selection of 6~33ºC, the pressure of the cooling h2o is .3Mpa, and the cooling drinking water ought to have no corrosion impact on copper and iron.
6.six If the earlier mentioned simple problems of use are exceeded, corresponding actions or special orders have to be taken.
