Four, complex attributes
4.one By incorporating a “Γ”-formed damping ring to the strong magnetic poles, the motor can provide a big sufficient commencing torque, a pulling torque and a reduced starting existing, which can make certain the sleek beginning and acceleration of the motor, and have a little affect on the energy grid, and meet the user load specifications .
four.2 The use of new insulating resources and insulation technologies, with tremendous strong insulation and voltage resistance.
4.3 The motor adopts course F insulation, and the temperature rise is assessed according to the temperature increase limit worth of class B insulation. It has a long provider daily life and a great air flow method, which helps make the device underneath various working conditions these kinds of as startup, overload, overexcitation, underexcitation, and shutdown. Make sure that the temperature rise of every component does not exceed the allowable restrict.
4.4 Through exact calculation and analysis, the composition of the rotor is identified. The substantial-electricity motor adopts the built-in composition engineering of shaft and choke to make the motor protected and trustworthy.
4.five The safety unit is advanced and full.
four.5.1 The stator windings and bearings are outfitted with temperature detection products, which can detect, alarm and vacation.
4.5.two Shutdown space heater with anti-condensation result.
Five, composition kind
five.1 The structure of this series of motors is typically horizontal, and the cooling technique is a shut circulating air cooling program, which is found at the bottom of the motor. For further-high-electricity motors, it is of box-type construction and drinking water-cooled.
five.2 The motor magnetic materials adopts large-high quality cold-rolled silicon steel sheet with high magnetic permeability and reduced reduction, which improves the functioning efficiency of the motor and decreases the operating cost of the motor. Rigid stator construction, the iron main is mounted on the supporting ribs of the frame in the circumferential course by way of the dovetail groove and compressed in sections with substantial stress, and all the forces are transmitted to the foundation via the body, minimizing vibration. The damping ring and the magnetic pole undertake a special fixing approach to avoid malfunctions caused by very poor make contact with all inside conductive human body connectors, fasteners, supports and screws on the rotating human body have anti-loosening actions to guarantee firmness and trustworthiness.
5.three The stator winding is taken care of with VPI as a entire dipping paint, which has substantial electrical performance, mechanical toughness, insulation performance, humidity resistance and thermal stability.
five.four The bearing is a sliding bearing with pressure oil circulation, which is put in in a bearing seat produced of forged metal. The sliding bearing has a spherical bearing that can automatically adjust the middle. The inner floor of the bearing is coated with a layer of Babbitt alloy to avoid power generation Lead-tin eutectic happens when the device is working at substantial temperature. The bearings are insulated to avert shaft currents.
six. Situations of Use
6.1 Voltage fluctuation: ±5% (It can operate at ±10% underneath the problem of seven.3 in GB755).
six.two Frequency fluctuation: ±2%.
6.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 drinking water of the air cooler need to be retained inside of the selection of six~33ºC, the pressure of the cooling water is .3Mpa, and the cooling drinking water ought to have no corrosion result on copper and iron.
six.six If the earlier mentioned basic circumstances of use are exceeded, corresponding measures or particular orders should be taken.
