电机系统未来发展方向在哪里

文章来源(yuan):发表时间(jian):2019-05-25 11:20:20

  电(dian)(dian)机(ji)(ji)体系(xi)节能也是大势所趋。为提高(gao)(gao)能效(xiao)(xiao)等级,工信(xin)部本年(nian)6月份(fen)公布了电(dian)(dian)机(ji)(ji)能效(xiao)(xiao)提高(gao)(gao)方案(an),到(dao)2015年(nian),实现(xian)电(dian)(dian)机(ji)(ji)产(chan)(chan)品升级换代,50%的低压(ya)三(san)相笼型异步(bu)电(dian)(dian)动(dong)机(ji)(ji)产(chan)(chan)品、40%的高(gao)(gao)压(ya)电(dian)(dian)动(dong)机(ji)(ji)产(chan)(chan)品达到(dao)高(gao)(gao)效(xiao)(xiao)电(dian)(dian)机(ji)(ji)能效(xiao)(xiao)标准规范;累计推行(xing)(xing)高(gao)(gao)效(xiao)(xiao)电(dian)(dian)机(ji)(ji)1.7亿千(qian)(qian)瓦(wa),筛选(xuan)在用(yong)低效(xiao)(xiao)电(dian)(dian)机(ji)(ji)1.6亿千(qian)(qian)瓦(wa),施行(xing)(xing)电(dian)(dian)机(ji)(ji)体系(xi)节能技(ji)改1亿千(qian)(qian)瓦(wa),施行(xing)(xing)筛选(xuan)电(dian)(dian)机(ji)(ji)高(gao)(gao)效(xiao)(xiao)再制造2000万(wan)千(qian)(qian)瓦(wa)。

  但是(shi)仅(jin)仅(jin)用(yong)(yong)高(gao)效电(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)替(ti)换一般(ban)电(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)对整个电(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)体(ti)系(xi)的节能(neng)(neng)(neng)效果提高(gao)并不显着,整个电(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)体(ti)系(xi)的节能(neng)(neng)(neng)才是(shi)真实(shi)的节能(neng)(neng)(neng)。因此,变(bian)(bian)频(pin)器(qi)(qi)(qi),伺(si)服,逆变(bian)(bian)器(qi)(qi)(qi)和专用(yong)(yong)电(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)驱动很多(duo)用(yong)(yong)在风机(ji)(ji)(ji)(ji)(ji)(ji)、泵、压(ya)缩机(ji)(ji)(ji)(ji)(ji)(ji)、升降(jiang)机(ji)(ji)(ji)(ji)(ji)(ji)、电(dian)(dian)(dian)(dian)焊机(ji)(ji)(ji)(ji)(ji)(ji)、电(dian)(dian)(dian)(dian)动车电(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)、空调压(ya)缩机(ji)(ji)(ji)(ji)(ji)(ji)、洗(xi)衣机(ji)(ji)(ji)(ji)(ji)(ji)电(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)和冰箱(xiang)压(ya)缩机(ji)(ji)(ji)(ji)(ji)(ji)中。变(bian)(bian)频(pin)器(qi)(qi)(qi)是(shi)电(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)体(ti)系(xi)节能(neng)(neng)(neng)的主(zhu)力,节能(neng)(neng)(neng)首要表现在风机(ji)(ji)(ji)(ji)(ji)(ji)、泵类的应用(yong)(yong)上(shang),选用(yong)(yong)变(bian)(bian)频(pin)器(qi)(qi)(qi)后(hou)(hou),可以经过下(xia)(xia)降(jiang)供(gong)(gong)电(dian)(dian)(dian)(dian)频(pin)率(lv)(lv)来下(xia)(xia)降(jiang)泵或(huo)风机(ji)(ji)(ji)(ji)(ji)(ji)的转速(su),跟着转速(su)的下(xia)(xia)降(jiang),功(gong)(gong)率(lv)(lv)会快速(su)下(xia)(xia)降(jiang)。同(tong)时(shi)变(bian)(bian)频(pin)器(qi)(qi)(qi)一般(ban)选用(yong)(yong)交直交变(bian)(bian)频(pin)供(gong)(gong)电(dian)(dian)(dian)(dian)的方法,交流异步电(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)吸收滞后(hou)(hou)的无功(gong)(gong)功(gong)(gong)率(lv)(lv),经过变(bian)(bian)频(pin)器(qi)(qi)(qi)供(gong)(gong)电(dian)(dian)(dian)(dian),对电(dian)(dian)(dian)(dian)网而言,功(gong)(gong)率(lv)(lv)因数也(ye)有了一定(ding)提高(gao),总体(ti)上(shang)节省(sheng)了一部(bu)分(fen)电(dian)(dian)(dian)(dian)网输电(dian)(dian)(dian)(dian)过程中损耗的电(dian)(dian)(dian)(dian)能(neng)(neng)(neng)。

  而变(bian)频器(qi),伺服(fu)驱动(dong),逆变(bian)器(qi)和专用控制器(qi)中(zhong)的(de)(de)(de)IPM模块,IGBT和MOSFET对节能降(jiang)耗(hao)起到(dao)关键性(xing)效果。客户对这些功(gong)率器(qi)材(cai)要求(qiu)也越(yue)来越(yue)多,比(bi)方(fang)要求(qiu)更低的(de)(de)(de)产品成本(ben)、更紧(jin)凑(cou)的(de)(de)(de)封装尺度、更好的(de)(de)(de)散热性(xing)能,对功(gong)率器(qi)材(cai)的(de)(de)(de)多样(yang)化也提出要求(qiu),比(bi)方(fang)低功(gong)耗(hao)器(qi)材(cai)、紧(jin)凑(cou)规划(hua)的(de)(de)(de)大(da)功(gong)率器(qi)材(cai)、低压大(da)功(gong)率器(qi)材(cai)、大(da)电(dian)流(liu)高电(dian)压器(qi)材(cai)等等。
