Four, technological characteristics By adding a “Γ”-formed damping ring to the reliable magnetic poles, the motor can give a large ample starting torque, a pulling torque and a decrease starting up current, which can make certain the smooth starting up and acceleration of the motor, and have a modest influence on the electrical power grid, and meet up with the user load specifications .
4.two The use of new insulating supplies and insulation technologies, with tremendous robust insulation and voltage resistance.
4.three The motor adopts course F insulation, and the temperature rise is assessed according to the temperature rise limit price of course B insulation. It has a long service lifestyle and a great air flow method, which tends to make the device under numerous operating conditions such as startup, overload, overexcitation, underexcitation, and shutdown. Make certain that the temperature increase of every element does not exceed the allowable limit.
4.4 Via exact calculation and evaluation, the construction of the rotor is established. The higher-energy motor adopts the integrated construction engineering of shaft and choke to make the motor protected and reputable.
four.5 The protection device is innovative and full. The stator windings and bearings are equipped with temperature detection gadgets, which can detect, alarm and journey.
4.five.two Shutdown area heater with anti-condensation effect.
5, construction type The composition of this sequence of motors is typically horizontal, and the cooling method is a shut circulating air cooling system, which is situated at the bottom of the motor. For further-large-electrical power motors, it is of box-type framework and water-cooled.
five.2 The motor magnetic content adopts high-high quality chilly-rolled silicon metal sheet with substantial magnetic permeability and lower reduction, which enhances the functioning performance of the motor and minimizes the working value of the motor. Rigid stator construction, the iron main is fastened on the supporting ribs of the frame in the circumferential path by way of the dovetail groove and compressed in sections with high pressure, and all the forces are transmitted to the base via the body, reducing vibration. The damping ring and the magnetic pole adopt a specific fixing technique to avoid malfunctions induced by bad contact all interior conductive body connectors, fasteners, supports and screws on the rotating physique have anti-loosening measures to make sure firmness and trustworthiness.
5.3 The stator winding is dealt with with VPI as a whole dipping paint, which has higher electrical efficiency, mechanical power, insulation efficiency, 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 solid steel. The sliding bearing has a spherical bearing that can instantly change the heart. The interior surface of the bearing is coated with a layer of Babbitt alloy to prevent power generation Direct-tin eutectic takes place when the machine is managing at large temperature. The bearings are insulated to avert shaft currents.
6. Conditions of Use
six.1 Voltage fluctuation: ±5% (It can operate at ±10% beneath the problem of 7.three in GB755).
6.2 Frequency fluctuation: ±2%.
six.3 The altitude does not exceed 5000m
6.4 The greatest ambient air temperature does not exceed +50ºC,
six.five The inlet temperature of the cooling water of the air cooler should be stored in the range of 6~33ºC, the pressure of the cooling water is .3Mpa, and the cooling h2o must have no corrosion effect on copper and iron.
six.6 If the earlier mentioned standard situations of use are exceeded, corresponding steps or particular orders should be taken.
