4, complex attributes
4.1 By incorporating a “Γ”-formed damping ring to the reliable magnetic poles, the motor can provide a massive sufficient beginning torque, a pulling torque and a reduced starting up existing, which can make sure the sleek commencing and acceleration of the motor, and have a little influence on the power grid, and satisfy the person load requirements .
four.2 The use of new insulating supplies and insulation engineering, with tremendous powerful insulation and voltage resistance.
four.three The motor adopts class F insulation, and the temperature increase is assessed in accordance to the temperature rise restrict value of course B insulation. It has a extended services existence and a good air flow system, which tends to make the unit underneath different functioning conditions this sort of as startup, overload, overexcitation, underexcitation, and shutdown. Guarantee that the temperature increase of every element does not exceed the allowable restrict.
four.4 Through correct calculation and evaluation, the composition of the rotor is determined. The high-electricity motor adopts the integrated structure technologies of shaft and choke to make the motor risk-free and dependable.
4.5 The security unit is advanced and complete.
four.five.one The stator windings and bearings are geared up with temperature detection units, which can detect, alarm and trip.
four.5.two Shutdown area heater with anti-condensation result.
5, construction variety
five.one The construction of this collection of motors is typically horizontal, and the cooling method is a shut circulating air cooling program, which is situated at the base of the motor. For further-higher-electrical power motors, it is of box-kind structure and water-cooled.
5.2 The motor magnetic substance adopts substantial-good quality cold-rolled silicon metal sheet with higher magnetic permeability and lower decline, which improves the working effectiveness of the motor and reduces the running expense of the motor. Rigid stator structure, the iron main is set on the supporting ribs of the frame in the circumferential course by means of the dovetail groove and compressed in sections with high force, and all the forces are transmitted to the foundation by means of the frame, minimizing vibration. The damping ring and the magnetic pole adopt a unique repairing approach to prevent malfunctions brought on by very poor speak to all interior conductive human body connectors, fasteners, supports and screws on the rotating entire body have anti-loosening steps to make sure firmness and reliability.
5.3 The stator winding is treated with VPI as a complete dipping paint, which has substantial electrical efficiency, mechanical toughness, insulation efficiency, humidity resistance and thermal balance.
5.four The bearing is a sliding bearing with force oil circulation, which is put in in a bearing seat produced of solid metal. The sliding bearing has a spherical bearing that can instantly alter the middle. The internal surface of the bearing is coated with a layer of Babbitt alloy to stop energy generation Direct-tin eutectic takes place when the machine is operating at high temperature. The bearings are insulated to avert shaft currents.
six. Circumstances of Use
6.1 Voltage fluctuation: ±5% (It can run at ±10% underneath the condition of 7.three in GB755).
six.2 Frequency fluctuation: ±2%.
six.three The altitude does not exceed 5000m
6.four The greatest ambient air temperature does not exceed +50ºC,
six.five The inlet temperature of the cooling h2o of the air cooler need to be stored inside the selection of 6~33ºC, the force of the cooling drinking water is .3Mpa, and the cooling water ought to have no corrosion result on copper and iron.
six.six If the over standard circumstances of use are exceeded, corresponding steps or unique orders need to be taken.
