摘要
交流电动机变频调速已成为当代电动机调速的潮流,它以体积小、质量轻、转矩大、精度高、功能强、可靠性好、操作简便和便于通信等功能优于以往的任何调速方式,如变极调速、调压调速、滑差调速、串级调速、整流子电动机调速、液力耦合调速乃至直流调速。因而在钢铁、有色金属、石油、石化、化纤、纺织、机械、电力、电子、建材、煤炭、医药、造纸、注塑、卷烟、吊车、城市供水及污水处理行业得到普遍应用。目前,日本的名牌变频器进入中国,占据变频器主要市场,欧美变频器也大量进入中国,占领变频器重要市场,台湾地区变频器在大陆也占有一席之地。21世纪,国产变频器大发展,以长三角、珠三角为主,全国约有百家。深圳有国产变频器生产厂27家,是变频器生产最发达地区。
Frequency converter has become dominant speed- controller in comporary years, because it is small in volume, light in weight, large in torque , high in precision, maniford in function, high is reliability, easy in handling and in communication. It is much better than any other speed controller, such as that by means of changing pole number of motor, voltage-regulation, slip-regulation, cascade regulation, commutation motor, hydraulic coupling regulation and directcurrent motor. It＇s application field includes industries in steel, color metal, petrol, petrol chemisty, chemistry fiber, texture, machinery, electric power, electronics, building, matereial, coalmining, medicine, paper, plastics, cigarettes, elevator, water treatment and supply. Japanese products of frequency changer has shared major parts in Chinese market, Europian and American products has also constantly flowed into our market; Taiwan products share a certain part of it. Since beginning of 21 century, domestic frequency converter product got a greater development, esp. in Yangzi Delta and Pear-river Delta, Shenzhen alone has 27 manufacturers of frequency convertor.
