Four, technical qualities
four.one By adding a “Γ”-formed damping ring to the sound magnetic poles, the motor can supply a huge enough commencing torque, a pulling torque and a lower starting existing, which can guarantee the sleek commencing and acceleration of the motor, and have a small effect on the electrical power grid, and meet up with the person load demands .
4.two The use of new insulating supplies and insulation engineering, with super strong insulation and voltage resistance.
4.3 The motor adopts course F insulation, and the temperature increase is assessed according to the temperature rise limit worth of course B insulation. It has a prolonged support existence and a great air flow program, which helps make the unit underneath numerous working situations this sort of as startup, overload, overexcitation, underexcitation, and shutdown. Make sure that the temperature rise of every element does not exceed the allowable limit.
four.4 By means of correct calculation and analysis, the construction of the rotor is identified. The large-electricity motor adopts the built-in construction engineering of shaft and choke to make the motor protected and dependable.
4.five The defense gadget is superior and comprehensive.
four.five.one The stator windings and bearings are geared up with temperature detection units, which can detect, alarm and excursion.
4.five.2 Shutdown space heater with anti-condensation impact.
5, construction type
five.1 The construction of this collection of motors is usually horizontal, and the cooling technique is a shut circulating air cooling method, which is found at the bottom of the motor. For further-large-electrical power motors, it is of box-variety construction and water-cooled.
five.two The motor magnetic substance adopts higher-high quality cold-rolled silicon metal sheet with high magnetic permeability and reduced loss, which improves the working efficiency of the motor and decreases the functioning cost of the motor. Rigid stator framework, the iron core is set on the supporting ribs of the body in the circumferential path through the dovetail groove and compressed in sections with high pressure, and all the forces are transmitted to the foundation through the body, reducing vibration. The damping ring and the magnetic pole adopt a unique repairing approach to avert malfunctions brought on by inadequate contact all inner conductive entire body connectors, fasteners, supports and screws on the rotating entire body have anti-loosening steps to ensure firmness and dependability.
5.3 The stator winding is treated with VPI as a entire dipping paint, which has higher electrical overall performance, mechanical energy, insulation performance, humidity resistance and thermal stability.
5.four The bearing is a sliding bearing with stress oil circulation, which is put in in a bearing seat created of forged steel. The sliding bearing has a spherical bearing that can automatically change the center. The interior surface area of the bearing is coated with a layer of Babbitt alloy to stop energy generation Guide-tin eutectic occurs when the equipment is working at large temperature. The bearings are insulated to prevent shaft currents.
6. Situations of Use
six.one Voltage fluctuation: ±5% (It can run at ±10% under the situation of seven.three in GB755).
six.two Frequency fluctuation: ±2%.
6.three The altitude does not exceed 5000m
6.4 The highest ambient air temperature does not exceed +50ºC,
6.5 The inlet temperature of the cooling h2o of the air cooler should be retained inside of the range of 6~33ºC, the force of the cooling h2o is .3Mpa, and the cooling h2o must have no corrosion result on copper and iron.
six.6 If the over simple situations of use are exceeded, corresponding actions or special orders need to be taken.
