4, technological attributes
4.1 By introducing a “Γ”-formed damping ring to the sound magnetic poles, the motor can offer a massive enough starting torque, a pulling torque and a reduced commencing present, which can make sure the smooth commencing and acceleration of the motor, and have a tiny effect on the energy grid, and satisfy the person load specifications .
4.two The use of new insulating supplies and insulation technology, with super sturdy insulation and voltage resistance.
4.3 The motor adopts class F insulation, and the temperature increase is assessed according to the temperature rise limit value of course B insulation. It has a extended provider existence and a great ventilation system, which makes the device below various operating conditions this sort of as startup, overload, overexcitation, underexcitation, and shutdown. Guarantee that the temperature rise of each portion does not exceed the allowable limit.
four.four Through correct calculation and analysis, the composition of the rotor is decided. The large-electrical power motor adopts the built-in composition technological innovation of shaft and choke to make the motor protected and trustworthy.
four.five The defense unit is innovative and total. The stator windings and bearings are geared up with temperature detection devices, which can detect, alarm and journey.
4.5.two Shutdown space heater with anti-condensation effect.
5, structure kind
5.1 The framework of this sequence of motors is generally horizontal, and the cooling technique is a shut circulating air cooling system, which is positioned at the base of the motor. For further-large-electrical power motors, it is of box-variety construction and drinking water-cooled.
five.two The motor magnetic substance adopts higher-quality cold-rolled silicon steel sheet with substantial magnetic permeability and minimal decline, which increases the functioning effectiveness of the motor and decreases the operating price of the motor. Rigid stator composition, the iron core is set on the supporting ribs of the body in the circumferential route by way of the dovetail groove and compressed in sections with higher stress, and all the forces are transmitted to the base via the body, minimizing vibration. The damping ring and the magnetic pole adopt a special repairing approach to stop malfunctions triggered by bad contact all inside conductive physique connectors, fasteners, supports and screws on the rotating entire body have anti-loosening actions to ensure firmness and dependability.
five.3 The stator winding is treated with VPI as a whole dipping paint, which has high electrical efficiency, mechanical energy, insulation efficiency, dampness resistance and thermal balance.
5.4 The bearing is a sliding bearing with pressure oil circulation, which is installed in a bearing seat manufactured of solid steel. The sliding bearing has a spherical bearing that can automatically modify the centre. The internal surface area of the bearing is coated with a layer of Babbitt alloy to prevent electricity technology Guide-tin eutectic occurs when the device is managing at higher temperature. The bearings are insulated to avoid shaft currents.
6. Problems of Use
six.1 Voltage fluctuation: ±5% (It can operate at ±10% under the issue of seven.3 in GB755).
6.2 Frequency fluctuation: ±2%.
6.3 The altitude does not exceed 5000m
6.four The optimum ambient air temperature does not exceed +50ºC,
six.five The inlet temperature of the cooling drinking water of the air cooler ought to be kept within the variety of 6~33ºC, the strain of the cooling h2o is .3Mpa, and the cooling h2o ought to have no corrosion influence on copper and iron.
six.6 If the above simple problems of use are exceeded, corresponding steps or special orders must be taken.
