变频(pin)器(qi)配套(tao)设备供应(ying)(ying)商提醒您:在变频(pin)调速系统中(zhong),降(jiang)速的(de)(de)(de)(de)(de)(de)基本方法就(jiu)是(shi)通(tong)(tong)过(guo)逐步降(jiang)低(di)给定频(pin)率来实现。当(dang)拖(tuo)动(dong)(dong)(dong)(dong)(dong)(dong)系统的(de)(de)(de)(de)(de)(de)惯性较大,电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)(de)(de)转(zhuan)速的(de)(de)(de)(de)(de)(de)下降(jiang)将(jiang)(jiang)跟不(bu)上电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)同(tong)步转(zhuan)速的(de)(de)(de)(de)(de)(de)下降(jiang),即电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)(de)(de)实际(ji)速度(du)比其同(tong)步速度(du)高,此时(shi)(shi)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)转(zhuan)子绕组(zu)切(qie)割旋转(zhuan)磁场(chang)(chang)磁力线(xian)的(de)(de)(de)(de)(de)(de)方向(xiang)(xiang)和(he)(he)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)恒速运行(xing)时(shi)(shi)正好相(xiang)反(fan)(fan),转(zhuan)子绕组(zu)的(de)(de)(de)(de)(de)(de)感应(ying)(ying)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)动(dong)(dong)(dong)(dong)(dong)(dong)势和(he)(he)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)(de)方向(xiang)(xiang)也(ye)都(dou)相(xiang)反(fan)(fan),所产(chan)(chan)生(sheng)的(de)(de)(de)(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁转(zhuan)矩也(ye)就(jiu)和(he)(he)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)旋转(zhuan)方向(xiang)(xiang)相(xiang)反(fan)(fan),电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)动(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)将(jiang)(jiang)出现负(fu)(fu)转(zhuan)矩,此时(shi)(shi)的(de)(de)(de)(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)动(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)实际(ji)为(wei)发电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)(ji),系统处于再生(sheng)制(zhi)动(dong)(dong)(dong)(dong)(dong)(dong)状态,将(jiang)(jiang)拖(tuo)动(dong)(dong)(dong)(dong)(dong)(dong)系统的(de)(de)(de)(de)(de)(de)动(dong)(dong)(dong)(dong)(dong)(dong)能(neng)(neng)(neng)回馈(kui)到(dao)(dao)变频(pin)器(qi)直(zhi)流(liu)(liu)母(mu)(mu)线(xian)上,使直(zhi)流(liu)(liu)母(mu)(mu)线(xian)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)压不(bu)断(duan)上升(sheng),甚至(zhi)达(da)到(dao)(dao)危险(xian)的(de)(de)(de)(de)(de)(de)地步(变频(pin)器(qi)损坏等(deng))。  一、制(zhi)动(dong)(dong)(dong)(dong)(dong)(dong)单(dan)(dan)元概述  制(zhi)动(dong)(dong)(dong)(dong)(dong)(dong)单(dan)(dan)元,全称为(wei)“变频(pin)器(qi)专用型(xing)能(neng)(neng)(neng)耗制(zhi)动(dong)(dong)(dong)(dong)(dong)(dong)单(dan)(dan)元”,或(huo)者(zhe)是(shi)“变频(pin)器(qi)专用型(xing)能(neng)(neng)(neng)量(liang)(liang)回馈(kui)单(dan)(dan)元”,主要(yao)用于控制(zhi)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)械(xie)负(fu)(fu)载比较重的(de)(de)(de)(de)(de)(de)、制(zhi)动(dong)(dong)(dong)(dong)(dong)(dong)速度(du)要(yao)求非常快(kuai)的(de)(de)(de)(de)(de)(de)场(chang)(chang)合,将(jiang)(jiang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)所产(chan)(chan)生(sheng)的(de)(de)(de)(de)(de)(de)再生(sheng)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)通(tong)(tong)过(guo)制(zhi)动(dong)(dong)(dong)(dong)(dong)(dong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻消(xiao)耗掉,或(huo)者(zhe)是(shi)将(jiang)(jiang)再生(sheng)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)反(fan)(fan)馈(kui)回电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源。  二、制(zhi)动(dong)(dong)(dong)(dong)(dong)(dong)单(dan)(dan)元的(de)(de)(de)(de)(de)(de)作用  当(dang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)动(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)快(kuai)速停(ting)车(che)时(shi)(shi),电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)动(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)会反(fan)(fan)馈(kui)能(neng)(neng)(neng)量(liang)(liang)给变频(pin)器(qi),造成直(zhi)流(liu)(liu)母(mu)(mu)线(xian)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)压升(sheng)高甚至(zhi)损坏IGBT,因此需要(yao)用制(zhi)动(dong)(dong)(dong)(dong)(dong)(dong)单(dan)(dan)元消(xiao)耗这部分能(neng)(neng)(neng)量(liang)(liang)以保护变频(pin)器(qi)。  三、变频(pin)器(qi)的(de)(de)(de)(de)(de)(de)制(zhi)动(dong)(dong)(dong)(dong)(dong)(dong)方式  1.动(dong)(dong)(dong)(dong)(dong)(dong)力制(zhi)动(dong)(dong)(dong)(dong)(dong)(dong)。  指利(li)用设置在直(zhi)流(liu)(liu)回路中(zhong)的(de)(de)(de)(de)(de)(de)制(zhi)动(dong)(dong)(dong)(dong)(dong)(dong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻吸收电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)动(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)(de)(de)再生(sheng)能(neng)(neng)(neng)量(liang)(liang)的(de)(de)(de)(de)(de)(de)方式。  2.回馈(kui)制(zhi)动(dong)(dong)(dong)(dong)(dong)(dong)。  主要(yao)针对电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)型(xing)变频(pin)器(qi)或(huo)整流(liu)(liu)部份装有逆(ni)变器(qi)的(de)(de)(de)(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)压型(xing)变频(pin)器(qi),将(jiang)(jiang)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)动(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)(de)(de)再生(sheng)能(neng)(neng)(neng)量(liang)(liang)反(fan)(fan)馈(kui)回交(jiao)流(liu)(liu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)网。  3.共用直(zhi)流(liu)(liu)母(mu)(mu)线(xian)的(de)(de)(de)(de)(de)(de)多逆(ni)变器(qi)传(chuan)动(dong)(dong)(dong)(dong)(dong)(dong)。  电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)动(dong)(dong)(dong)(dong)(dong)(dong)机(ji)(ji)(ji)(ji)(ji)(ji)(ji)A的(de)(de)(de)(de)(de)(de)再生(sheng)能(neng)(neng)(neng)量(liang)(liang)反(fan)(fan)馈(kui)到(dao)(dao)公共的(de)(de)(de)(de)(de)(de)直(zhi)流(liu)(liu)母(mu)(mu)线(xian)上,再通(tong)(tong)过(guo)...
