Four, technical traits
four.one By including a “Γ”-formed damping ring to the solid magnetic poles, the motor can provide a massive ample beginning torque, a pulling torque and a reduce beginning current, which can ensure the sleek beginning and acceleration of the motor, and have a tiny effect on the electrical power grid, and fulfill the user load specifications .
4.2 The use of new insulating components and insulation technologies, with super powerful insulation and voltage resistance.
four.3 The motor adopts class F insulation, and the temperature increase is assessed according to the temperature rise limit benefit of course B insulation. It has a prolonged provider existence and a excellent ventilation system, which makes the device below a variety of operating situations such as startup, overload, overexcitation, underexcitation, and shutdown. Make certain that the temperature increase of every element does not exceed the allowable restrict.
four.4 Through exact calculation and evaluation, the composition of the rotor is established. The high-energy motor adopts the integrated construction engineering of shaft and choke to make the motor risk-free and dependable.
four.five The defense gadget is superior and total.
4.five.1 The stator windings and bearings are outfitted with temperature detection products, which can detect, alarm and trip.
four.five.2 Shutdown place heater with anti-condensation impact.
5, framework kind
5.one The construction of this sequence of motors is usually horizontal, and the cooling technique is a closed circulating air cooling method, which is situated at the base of the motor. For added-high-electrical power motors, it is of box-sort composition and h2o-cooled.
five.2 The motor magnetic content adopts higher-good quality cold-rolled silicon steel sheet with substantial magnetic permeability and reduced decline, which enhances the operating effectiveness of the motor and reduces the functioning expense of the motor. Rigid stator construction, the iron core is fixed on the supporting ribs of the body in the circumferential route via the dovetail groove and compressed in sections with higher force, and all the forces are transmitted to the base via the body, reducing vibration. The damping ring and the magnetic pole undertake a specific fixing method to avert malfunctions caused by bad get in touch with all interior conductive body connectors, fasteners, supports and screws on the rotating entire body have anti-loosening steps to make certain firmness and dependability.
5.three The stator winding is dealt with with VPI as a total dipping paint, which has large electrical overall performance, mechanical toughness, insulation efficiency, dampness resistance and thermal balance.
5.four The bearing is a sliding bearing with stress oil circulation, which is mounted in a bearing seat manufactured of forged metal. The sliding bearing has a spherical bearing that can routinely alter the centre. The internal surface area of the bearing is coated with a layer of Babbitt alloy to avoid electricity era Direct-tin eutectic happens when the equipment is running at higher temperature. The bearings are insulated to prevent shaft currents.
six. Problems of Use
six.one Voltage fluctuation: ±5% (It can operate at ±10% under the problem of 7.three in GB755).
6.2 Frequency fluctuation: ±2%.
six.3 The altitude does not exceed 5000m
six.4 The optimum ambient air temperature does not exceed +50ºC,
six.5 The inlet temperature of the cooling drinking water of the air cooler should be kept in the assortment of six~33ºC, the pressure of the cooling water is .3Mpa, and the cooling h2o must have no corrosion result on copper and iron.
6.6 If the over fundamental situations of use are exceeded, corresponding actions or special orders must be taken.
