Four, specialized traits
four.one By introducing a “Γ”-formed damping ring to the strong magnetic poles, the motor can provide a massive sufficient commencing torque, a pulling torque and a decrease commencing current, which can guarantee the smooth starting up and acceleration of the motor, and have a small affect on the electricity grid, and meet up with the person load needs .
four.two The use of new insulating supplies and insulation technological innovation, with super strong insulation and voltage resistance.
four.three The motor adopts course F insulation, and the temperature rise is assessed in accordance to the temperature rise restrict value of course B insulation. It has a long service life and a very good ventilation program, which can make the device under a variety of functioning circumstances these kinds of as startup, overload, overexcitation, underexcitation, and shutdown. Guarantee that the temperature rise of each element does not exceed the allowable limit.
four.four By means of precise calculation and examination, the framework of the rotor is identified. The substantial-electrical power motor adopts the integrated framework technology of shaft and choke to make the motor risk-free and dependable.
four.five The safety gadget is superior and comprehensive.
four.five.1 The stator windings and bearings are geared up with temperature detection devices, which can detect, alarm and excursion.
four.five.two Shutdown area heater with anti-condensation influence.
5, structure kind
5.1 The construction of this series of motors is typically horizontal, and the cooling approach is a shut circulating air cooling method, which is situated at the bottom of the motor. For additional-substantial-electrical power motors, it is of box-kind construction and drinking water-cooled.
5.two The motor magnetic materials adopts higher-high quality chilly-rolled silicon steel sheet with substantial magnetic permeability and lower loss, which improves the operating effectiveness of the motor and lowers the operating value of the motor. Rigid stator framework, the iron core is set on the supporting ribs of the frame in the circumferential direction by means of the dovetail groove and compressed in sections with substantial stress, and all the forces are transmitted to the foundation through the body, minimizing vibration. The damping ring and the magnetic pole undertake a particular correcting approach to avoid malfunctions brought on by very poor make contact with all inner conductive human body connectors, fasteners, supports and screws on the rotating physique have anti-loosening steps to make sure firmness and dependability.
five.three The stator winding is taken care of with VPI as a entire dipping paint, which has high electrical functionality, mechanical energy, insulation efficiency, humidity resistance and thermal stability.
5.4 The bearing is a sliding bearing with stress oil circulation, which is installed in a bearing seat made of cast metal. The sliding bearing has a spherical bearing that can immediately change the heart. The inner floor of the bearing is coated with a layer of Babbitt alloy to stop electricity generation Lead-tin eutectic happens when the equipment is running at high temperature. The bearings are insulated to prevent shaft currents.
six. Conditions of Use
6.1 Voltage fluctuation: ±5% (It can run at ±10% below the problem of 7.three in GB755).
6.2 Frequency fluctuation: ±2%.
6.three The altitude does not exceed 5000m
6.4 The optimum ambient air temperature does not exceed +50ºC,
six.5 The inlet temperature of the cooling h2o of the air cooler should be retained in the range of 6~33ºC, the pressure of the cooling water is .3Mpa, and the cooling drinking water must have no corrosion impact on copper and iron.
six.6 If the earlier mentioned fundamental circumstances of use are exceeded, corresponding actions or unique orders need to be taken.
