| Abstract:The application of large synchronous high voltage motor in high concent ration disc refining system was introduced.According to the production needs of high concentrated disc refiner and the requirements of the factory power grid， the four ways of direct starting， reactor starting， autotransformer start and frequency converter start of the main motor were analyzed and calculated， to determine the right start mode.Moan while the instantaneous trip protection， overload protection and differential protection were analyzed and calculated during the running of the motor.The proper setting value was determined． |
