Details:
An overview of
       
YB355-450 series high voltage flameproof three-phase asynchronous motor is a closed fan cooled squirrel cage electric company's own design with the international advanced level
Machine. The use of advanced design philosophy, absorbing domestic and foreign advanced technology in the design of such motor. With small size, light weight, power, efficiency
High temperature rise margin performance, vibration and ran a small, low noise, excellent performance, explosion-proof, high reliability, can meet a variety of needs, and easy maintenance.
       
YB355-450 series high voltage flameproof three-phase asynchronous motors of the latest national standards and the International Electrotechnical Commission (IEC) standard power range from 160kW to 500kW. YB355-450 series high voltage flameproof three asynchronous motors meet GB755 "rotary motor fixed and performance ", to GB3836.1 explosive gas atmospheres - Electrical equipment - Part 1: General requirements", and GB3836.2 explosive gas atmospheres - electrical equipment - Part 2: Flameproof "d" "provisions, made of flameproof motor, explosion-proof mark ExdI AT4 ExdII ExdII BT4,, ExdII CT4, apply to explosive gas atmospheres of Zone 1 and Zone 2 dangerous places.
       
Exd I apply to coal mine methane or coal dust, non-mining face for explosive gas atmospheres.
       
Exd II AT4 factory Class A, Class II temperature group T1, T2, T3 and T4 group explosive gas environment.
       
Exd II BT4 apply to the factory Class II Class B temperature groups T1, T2, T3 and T4 group explosive gas environment.
       
Exd II CT4 applicable to Class II Grade C, the temperature groups T1, T2, T3 and T4 group explosive gas environment in the factory.
       
The motor of the main shell and the junction box protection class is IP54, can also be made to IP55. Derived on this basis, outdoor (W), the Humid Tropics (TH), outdoor hot and humid with (THW-), indoor and anti-middle-corrosion type (F1), strong anti-corrosion type (F2) in the indoor and outdoor anti-middle-corrosion type ( WF1), outdoor, strong anti-corrosive (WF2), derived three-phase asynchronous motor performance, installation Dimensions and basic series of same
 
 
Second, the Structure
    
3.1YB355-450 series high voltage flameproof three-phase asynchronous motor (hereinafter referred to as the motor), insulation class F, stator windings with double glass and film wrapped with copper flat wound is made, Having VPI overall impregnated, more high dielectric strength, moisture resistance and thermal stability.
    
3.2 motor with a squirrel cage cast aluminum or copper structure.
    
3.3 The junction box has a spacious space for wiring, you can access the copper and aluminum cables. Fixed wiring bolt insulating sleeves made of high quality DMC pressure plastic, the location of the junction box at the top.
    
3.4 motor cooling method is IC411, and automatically cycle the way of ventilation and cooling.
    
3.5 motor, explosion-proof structure of the explosion-proof type of cylindrical, planar and axial curved road.
    
3.6 The motor may need to set the space heater, the components of the stator winding temperature and bearing temperature measurement devices and explosion-proof temperature monitoring instruments.
    
The 3.7 motor is generally rolling bearing greased with non-stop machine lubrication device. By optimizing the bearing structure design, improved bearing life, reduce the chance of motor axle accident occurred, and to improve the reliability of the motor is running.
Third, the conditions of use
      
4.1 ambient temperature changes with the seasons, but the minimum ambient air temperature of not less than -15 ℃, the highest ambient air temperature does not exceed 40 ℃.
      
4.2 altitude less than 1000m.
      
4.3 rated voltage 6kV, 10kV.
      
4.4 rated frequency of 50Hz.
      
4.5 The quota is the continuous duty (S1) is the benchmark for fixed.
