YB2-400-2/4/6 10kV HV Explosion Proof Motor
-
YB2 series 6kV flameproof three-phase asynchronous motors (frame size: 355~560) shall comply with the industry standard JB/T 8674-2007 Technical Specifications for YB2 series high-voltage flameproof three-phase asynchronous motors (Frame size: 355~560).Three-phase AC power supply is adopted, the allowable fluctuation value of power supply voltage is ±5% of rated voltage under rated frequency. When the power supply voltage is within a certain fluctuation limit, the allowable temperature rise limit of the motor is allowed to rise no more than 5K (motors with 1,000kW and below) or 10K (motors more than 1,000kW). When motor operates under rated voltage, the allowable fluctuation value of power supply frequency is ±1% of rated operating frequency.When motor operates under supply voltage and frequency that are synchronous under some fluctuation values within fluctuation limit, sum of absolute values of the two fluctuation values shall be within 5%. ven if the plateau anti corona treatment is adopted, the altitude of the installation site of this series of motors should not exceed 4,000 m.
