Four, specialized traits
four.1 By adding a “Γ”-shaped damping ring to the sound magnetic poles, the motor can provide a massive enough starting up torque, a pulling torque and a reduced commencing current, which can make sure the sleek starting and acceleration of the motor, and have a little influence on the power grid, and meet up with the consumer load requirements .
4.2 The use of new insulating supplies and insulation technological innovation, with tremendous powerful insulation and voltage resistance.
4.three The motor adopts course F insulation, and the temperature rise is assessed in accordance to the temperature increase restrict price of class B insulation. It has a long provider existence and a good ventilation technique, which tends to make the device under a variety of functioning problems this sort of as startup, overload, overexcitation, underexcitation, and shutdown. Guarantee that the temperature increase of every single part does not exceed the allowable restrict.
4.4 By means of exact calculation and evaluation, the structure of the rotor is established. The higher-electrical power motor adopts the integrated composition technology of shaft and choke to make the motor safe and reliable.
four.5 The security device is sophisticated and full.
4.five.1 The stator windings and bearings are equipped with temperature detection units, which can detect, alarm and vacation.
4.5.2 Shutdown place heater with anti-condensation impact.
Five, structure type
5.1 The composition of this series of motors is usually horizontal, and the cooling method is a shut circulating air cooling method, which is located at the bottom of the motor. For additional-high-electricity motors, it is of box-type composition and water-cooled.
five.two The motor magnetic materials adopts large-high quality chilly-rolled silicon steel sheet with high magnetic permeability and lower decline, which improves the functioning efficiency of the motor and reduces the functioning value of the motor. Rigid stator structure, the iron core is mounted on the supporting ribs of the body in the circumferential direction through the dovetail groove and compressed in sections with large strain, and all the forces are transmitted to the foundation by way of the frame, minimizing vibration. The damping ring and the magnetic pole adopt a special repairing strategy to stop malfunctions induced by bad get in touch with all inner conductive human body connectors, fasteners, supports and screws on the rotating entire body have anti-loosening actions to guarantee firmness and dependability.
5.three The stator winding is treated with VPI as a total dipping paint, which has high electrical overall performance, mechanical energy, insulation performance, dampness resistance and thermal stability.
five.4 The bearing is a sliding bearing with strain oil circulation, which is set up in a bearing seat created of solid steel. The sliding bearing has a spherical bearing that can immediately change the center. The internal floor of the bearing is coated with a layer of Babbitt alloy to prevent power generation Lead-tin eutectic takes place when the device is working at substantial temperature. The bearings are insulated to prevent shaft currents.
six. Problems of Use
six.one Voltage fluctuation: ±5% (It can operate at ±10% beneath the issue of 7.3 in GB755).
6.2 Frequency fluctuation: ±2%.
six.three The altitude does not exceed 5000m
six.4 The highest ambient air temperature does not exceed +50ºC,
6.5 The inlet temperature of the cooling drinking water of the air cooler should be kept within the assortment of 6~33ºC, the force of the cooling water is .3Mpa, and the cooling drinking water must have no corrosion impact on copper and iron.
six.six If the over basic circumstances of use are exceeded, corresponding actions or special orders need to be taken.
