4, technological traits
4.one By adding a “Γ”-formed damping ring to the strong magnetic poles, the motor can supply a huge enough starting up torque, a pulling torque and a reduce commencing existing, which can guarantee the easy starting up and acceleration of the motor, and have a small affect on the electricity grid, and satisfy the consumer load requirements .
four.2 The use of new insulating components and insulation technological innovation, with tremendous robust insulation and voltage resistance.
four.3 The motor adopts class F insulation, and the temperature increase is assessed according to the temperature increase restrict worth of class B insulation. It has a lengthy provider life and a good ventilation method, which helps make the unit beneath various working circumstances these kinds of as startup, overload, overexcitation, underexcitation, and shutdown. Ensure that the temperature rise of each and every portion does not exceed the allowable restrict.
four.4 By way of accurate calculation and evaluation, the construction of the rotor is decided. The substantial-electrical power motor adopts the built-in construction technological innovation of shaft and choke to make the motor secure and trustworthy.
4.5 The security device is superior and total.
4.5.1 The stator windings and bearings are equipped with temperature detection units, which can detect, alarm and trip.
4.5.2 Shutdown space heater with anti-condensation impact.
5, construction variety
5.one The composition of this collection of motors is typically horizontal, and the cooling approach is a shut circulating air cooling method, which is located at the bottom of the motor. For extra-large-electrical power motors, it is of box-kind structure and h2o-cooled.
five.2 The motor magnetic content adopts higher-top quality cold-rolled silicon metal sheet with high magnetic permeability and minimal reduction, which increases the operating efficiency of the motor and minimizes the running price of the motor. Rigid stator composition, the iron main is set on the supporting ribs of the body in the circumferential direction by way of the dovetail groove and compressed in sections with higher force, and all the forces are transmitted to the foundation through the body, minimizing vibration. The damping ring and the magnetic pole undertake a particular correcting strategy to prevent malfunctions induced by inadequate make contact with all internal conductive physique connectors, fasteners, supports and screws on the rotating body have anti-loosening measures to make sure firmness and reliability.
five.three The stator winding is treated with VPI as a total dipping paint, which has large electrical functionality, mechanical power, insulation overall performance, humidity resistance and thermal security.
five.four The bearing is a sliding bearing with stress oil circulation, which is mounted in a bearing seat made of solid metal. The sliding bearing has a spherical bearing that can automatically change the middle. The interior surface area of the bearing is coated with a layer of Babbitt alloy to stop energy technology Guide-tin eutectic occurs when the equipment is managing at high temperature. The bearings are insulated to avoid shaft currents.
six. Situations of Use
6.1 Voltage fluctuation: ±5% (It can run at ±10% under the situation of 7.three in GB755).
six.2 Frequency fluctuation: ±2%.
6.3 The altitude does not exceed 5000m
6.4 The highest ambient air temperature does not exceed +50ºC,
six.5 The inlet temperature of the cooling drinking water of the air cooler need to be kept within the variety of six~33ºC, the strain of the cooling drinking water is .3Mpa, and the cooling h2o ought to have no corrosion impact on copper and iron.
6.six If the earlier mentioned standard circumstances of use are exceeded, corresponding steps or specific orders have to be taken.
