Four, complex attributes
four.1 By introducing a “Γ”-shaped damping ring to the strong magnetic poles, the motor can offer a huge enough starting up torque, a pulling torque and a reduced starting present, which can make certain the easy starting and acceleration of the motor, and have a small effect on the energy grid, and satisfy the person load needs .
4.two The use of new insulating resources and insulation technological innovation, 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 increase limit price of course B insulation. It has a prolonged support existence and a very good ventilation program, which makes the device below a variety of functioning conditions such as startup, overload, overexcitation, underexcitation, and shutdown. Guarantee that the temperature rise of each portion does not exceed the allowable restrict.
4.four Via accurate calculation and analysis, the framework of the rotor is identified. The higher-energy motor adopts the integrated composition technological innovation of shaft and choke to make the motor protected and dependable.
4.five The defense gadget is superior and complete.
four.5.1 The stator windings and bearings are outfitted with temperature detection units, which can detect, alarm and vacation.
4.five.2 Shutdown space heater with anti-condensation influence.
5, construction kind
five.1 The framework of this sequence of motors is generally horizontal, and the cooling approach is a closed circulating air cooling method, which is positioned at the base of the motor. For extra-substantial-power motors, it is of box-variety structure and h2o-cooled.
5.2 The motor magnetic substance adopts high-high quality cold-rolled silicon metal sheet with large magnetic permeability and low reduction, which increases the working performance of the motor and decreases the operating value of the motor. Rigid stator structure, the iron core is mounted on the supporting ribs of the body in the circumferential route by way of the dovetail groove and compressed in sections with higher force, and all the forces are transmitted to the base by way of the body, reducing vibration. The damping ring and the magnetic pole undertake a particular repairing method to avert malfunctions brought on by inadequate contact all interior conductive body connectors, fasteners, supports and screws on the rotating body have anti-loosening actions to guarantee firmness and dependability.
5.3 The stator winding is taken care of with VPI as a total dipping paint, which has substantial electrical efficiency, mechanical power, insulation overall performance, moisture resistance and thermal steadiness.
five.4 The bearing is a sliding bearing with strain oil circulation, which is set up in a bearing seat produced of solid metal. The sliding bearing has a spherical bearing that can routinely adjust the heart. The internal floor of the bearing is coated with a layer of Babbitt alloy to prevent electricity era Guide-tin eutectic occurs when the equipment is running at high temperature. The bearings are insulated to prevent shaft currents.
6. Situations of Use
six.1 Voltage fluctuation: ±5% (It can operate at ±10% under the issue of seven.three in GB755).
six.2 Frequency fluctuation: ±2%.
six.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 drinking water of the air cooler must be held inside the selection of six~33ºC, the stress of the cooling h2o is .3Mpa, and the cooling water should have no corrosion influence on copper and iron.
six.6 If the over standard situations of use are exceeded, corresponding measures or specific orders need to be taken.
