双速风机绕组接法与配电主回路设计简析

Brief Analysis of the Design of Winding Type and Main Circuit of Double Speed Fan

根据民用建筑中双速风机额定功率与电动机型号、同步转速的对应关系,以及电动机同步转速与定子绕组接线型式的对应关系,建立双速风机额定功率与配装的两速电动机定子绕组接法的对应关系,并分别图解△/YY型及Y/Y型接法双速风机的配电主回路。

According to the corresponding relationship between the rated power of double speed fan and the motor type and synchronous speed in civil buildings,as well as the corresponding relationship between the synchronous speed of motor and the wiring type of stator winding,the relationship between the related power of double speed fan and the type of stator winding of double speed motor is established,and the power distribution of double speed fan with△/YY wiring typeand Y/Y wiringtype are illustrated.
