4, complex traits
four.one By including a “Γ”-formed damping ring to the reliable magnetic poles, the motor can give a big sufficient starting torque, a pulling torque and a reduce starting existing, which can make sure the easy commencing and acceleration of the motor, and have a small affect on the energy grid, and meet the consumer load needs .
4.2 The use of new insulating components and insulation engineering, with super robust insulation and voltage resistance.
four.3 The motor adopts class F insulation, and the temperature rise is assessed according to the temperature increase limit value of class B insulation. It has a lengthy services existence and a very good ventilation system, which can make the unit beneath various operating situations this sort of as startup, overload, overexcitation, underexcitation, and shutdown. Guarantee that the temperature increase of each and every element does not exceed the allowable restrict.
4.4 Via precise calculation and investigation, the framework of the rotor is determined. The large-electrical power motor adopts the built-in composition technology of shaft and choke to make the motor safe and reliable.
4.five The defense device is sophisticated and total.
four.5.one The stator windings and bearings are geared up with temperature detection products, which can detect, alarm and vacation.
4.five.2 Shutdown room heater with anti-condensation impact.
5, construction kind
5.1 The construction of this collection of motors is typically horizontal, and the cooling strategy is a closed circulating air cooling method, which is found at the base of the motor. For extra-higher-energy motors, it is of box-variety structure and water-cooled.
five.two The motor magnetic substance adopts large-quality chilly-rolled silicon metal sheet with higher magnetic permeability and minimal loss, which increases the doing work effectiveness of the motor and lowers the running expense of the motor. Rigid stator composition, the iron core is fixed on the supporting ribs of the frame in the circumferential path by way of the dovetail groove and compressed in sections with higher strain, and all the forces are transmitted to the foundation by way of the body, reducing vibration. The damping ring and the magnetic pole undertake a special repairing approach to avoid malfunctions caused by bad make contact with all internal conductive entire body connectors, fasteners, supports and screws on the rotating physique have anti-loosening measures to ensure firmness and dependability.
5.3 The stator winding is handled with VPI as a total dipping paint, which has large electrical overall performance, mechanical toughness, insulation functionality, dampness resistance and thermal stability.
five.4 The bearing is a sliding bearing with stress oil circulation, which is mounted in a bearing seat created of forged metal. The sliding bearing has a spherical bearing that can automatically adjust the centre. The inner floor of the bearing is coated with a layer of Babbitt alloy to avoid electrical power technology Guide-tin eutectic happens when the machine is managing at high temperature. The bearings are insulated to avoid shaft currents.
six. Conditions of Use
six.one Voltage fluctuation: ±5% (It can run at ±10% underneath the problem of seven.3 in GB755).
6.two Frequency fluctuation: ±2%.
six.three The altitude does not exceed 5000m
6.four The maximum ambient air temperature does not exceed +50ºC,
six.five The inlet temperature of the cooling h2o of the air cooler should be kept in the variety of 6~33ºC, the stress of the cooling water is .3Mpa, and the cooling drinking water need to have no corrosion impact on copper and iron.
6.six If the previously mentioned simple situations of use are exceeded, corresponding actions or special orders should be taken.
