4, complex characteristics
4.one By adding a “Γ”-formed damping ring to the strong magnetic poles, the motor can supply a big ample commencing torque, a pulling torque and a reduced commencing present, which can make sure the smooth beginning and acceleration of the motor, and have a modest affect on the electricity grid, and satisfy the person load demands .
four.2 The use of new insulating resources and insulation technologies, with super strong insulation and voltage resistance.
four.3 The motor adopts class F insulation, and the temperature increase is assessed in accordance to the temperature rise restrict benefit of course B insulation. It has a extended service lifestyle and a very good air flow technique, which tends to make the unit underneath numerous functioning situations this kind of as startup, overload, overexcitation, underexcitation, and shutdown. Make sure that the temperature rise of each element does not exceed the allowable limit.
4.4 By way of precise calculation and investigation, the composition of the rotor is decided. The substantial-electrical power motor adopts the integrated framework technology of shaft and choke to make the motor secure and trustworthy.
4.5 The defense unit is sophisticated and complete.
4.5.one The stator windings and bearings are geared up with temperature detection products, which can detect, alarm and trip.
4.5.two Shutdown area heater with anti-condensation result.
5, composition kind
five.1 The construction of this series of motors is usually horizontal, and the cooling method is a shut circulating air cooling method, which is located at the base of the motor. For further-higher-power motors, it is of box-kind construction and h2o-cooled.
five.two The motor magnetic substance adopts large-high quality cold-rolled silicon metal sheet with higher magnetic permeability and minimal decline, which increases the functioning efficiency of the motor and decreases the operating price of the motor. Rigid stator composition, the iron core is set on the supporting ribs of the frame in the circumferential direction via the dovetail groove and compressed in sections with higher pressure, and all the forces are transmitted to the base via the body, minimizing vibration. The damping ring and the magnetic pole adopt a special repairing strategy to stop malfunctions induced by very poor get in touch with all internal conductive physique connectors, fasteners, supports and screws on the rotating physique have anti-loosening steps to guarantee firmness and dependability.
5.three The stator winding is taken care of with VPI as a complete dipping paint, which has high electrical performance, mechanical toughness, insulation efficiency, dampness resistance and thermal security.
5.four The bearing is a sliding bearing with strain oil circulation, which is set up in a bearing seat created of forged metal. The sliding bearing has a spherical bearing that can automatically modify the centre. The interior area of the bearing is coated with a layer of Babbitt alloy to avert energy era Direct-tin eutectic happens when the equipment is operating at high temperature. The bearings are insulated to avoid shaft currents.
six. Circumstances of Use
6.1 Voltage fluctuation: ±5% (It can operate at ±10% beneath the issue of seven.3 in GB755).
six.two Frequency fluctuation: ±2%.
six.three The altitude does not exceed 5000m
6.4 The optimum ambient air temperature does not exceed +50ºC,
six.five The inlet temperature of the cooling water of the air cooler need to be retained inside of the variety of six~33ºC, the force of the cooling h2o is .3Mpa, and the cooling water must have no corrosion influence on copper and iron.
six.6 If the over simple problems of use are exceeded, corresponding steps or special orders should be taken.
