Four, technical characteristics
four.1 By including a “Γ”-shaped damping ring to the reliable magnetic poles, the motor can give a huge enough starting torque, a pulling torque and a lower starting up present, which can make sure the clean starting and acceleration of the motor, and have a little affect on the power grid, and meet the user load requirements .
4.two The use of new insulating materials and insulation technological innovation, with tremendous strong insulation and voltage resistance.
4.3 The motor adopts course F insulation, and the temperature increase is assessed in accordance to the temperature increase restrict value of course B insulation. It has a extended services life and a great ventilation system, which tends to make the unit under various doing work circumstances this kind of as startup, overload, overexcitation, underexcitation, and shutdown. Ensure that the temperature rise of every single part does not exceed the allowable restrict.
four.4 Through accurate calculation and examination, the framework of the rotor is identified. The substantial-electricity motor adopts the built-in composition technologies of shaft and choke to make the motor protected and reliable.
four.5 The security device is superior and complete.
four.five.one The stator windings and bearings are equipped with temperature detection devices, which can detect, alarm and excursion.
four.five.two Shutdown place heater with anti-condensation influence.
Five, composition variety
5.one The composition of this series of motors is typically horizontal, and the cooling method is a shut circulating air cooling method, which is found at the bottom of the motor. For added-higher-power motors, it is of box-sort construction and water-cooled.
five.2 The motor magnetic substance adopts substantial-top quality chilly-rolled silicon metal sheet with substantial magnetic permeability and lower decline, which increases the operating effectiveness of the motor and minimizes the functioning value of the motor. Rigid stator construction, the iron core is set on the supporting ribs of the body in the circumferential path by way of the dovetail groove and compressed in sections with substantial pressure, and all the forces are transmitted to the base by way of the body, minimizing vibration. The damping ring and the magnetic pole undertake a unique correcting method to stop malfunctions caused by inadequate make contact with all interior conductive human body connectors, fasteners, supports and screws on the rotating human body have anti-loosening steps to ensure firmness and trustworthiness.
five.3 The stator winding is taken care of with VPI as a complete dipping paint, which has large electrical overall performance, mechanical power, insulation functionality, humidity resistance and thermal steadiness.
5.four The bearing is a sliding bearing with pressure oil circulation, which is installed in a bearing seat manufactured of cast metal. The sliding bearing has a spherical bearing that can immediately change the center. The inner area of the bearing is coated with a layer of Babbitt alloy to avert electrical power era Direct-tin eutectic occurs when the device is working at large temperature. The bearings are insulated to avert shaft currents.
six. Conditions of Use
6.1 Voltage fluctuation: ±5% (It can run at ±10% under the situation of seven.three in GB755).
six.2 Frequency fluctuation: ±2%.
6.3 The altitude does not exceed 5000m
six.four The highest ambient air temperature does not exceed +50ºC,
six.5 The inlet temperature of the cooling drinking water of the air cooler should be held within the assortment of 6~33ºC, the force of the cooling drinking water is .3Mpa, and the cooling water ought to have no corrosion influence on copper and iron.
6.six If the above simple circumstances of use are exceeded, corresponding actions or specific orders need to be taken.
