Application of Electrical Installation Technology for Large Synchronous Motors in Project Engineering
Based on the experience of electrical installation of three 10 kV 7350KW positive pressure shell type variable frequency starting brushless excitation synchronous motors in the 2.2 million ton/year hydrocracking unit of Hengyi(Brunei)PMB petrochemical project,this paper analyzes the electrical installation points of on-site assembly of positive pressure shell type variable frequency starting brushless excitation synchronous motors.The focus is on exploring how to ensure the insulation characteristics and dehumidification methods of this synchronous motor in humid and rainy environments all year round,which can provide reference for the electrical installation of large synchronous motors of the same type.
