DGQ-G系(xi)列高壓固態軟起動柜

型 號：DGQ-G

大(da)型電(dian)(dian)動(dong)(dong)機(ji)(ji)在全壓直接起(qi)(qi)(qi)動(dong)(dong)時(shi)，起(qi)(qi)(qi)動(dong)(dong)電(dian)(dian)流會(hui)達(da)到額定電(dian)(dian)流的5～7倍(bei)，全壓起(qi)(qi)(qi)動(dong)(dong)將使所在電(dian)(dian)網系(xi)統壓降合理大(da)，這(zhe)會(hui)破壞同網其(qi)它設備的正常運(yun)行，嚴重時(shi)甚(shen)至會(hui)引起(qi)(qi)(qi)電(dian)(dian)網失去穩(wen)定，產(chan)生(sheng)系(xi)統故障跳閘。如(ru)果直接起(qi)(qi)(qi)動(dong)(dong)，也會(hui)產(chan)生(sheng)較高(gao)的峰值(zhi)轉矩，從(cong)而對電(dian)(dian)動(dong)(dong)機(ji)(ji)及整個機(ji)(ji)械裝(zhuang)置造成有害的沖(chong)擊。因此，200kW以(yi)上電(dian)(dian)機(ji)(ji)需采用(yong)軟啟動(dong)(dong)。


      高壓(ya)軟起(qi)動(dong)(dong)(dong)是(shi)一種新(xin)型智能電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機起(qi)動(dong)(dong)(dong)裝(zhuang)置, 適(shi)用(yong)于(yu)鼠(shu)籠(long)式(shi)異步(bu)、同步(bu)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機。它是(shi)集(ji)起(qi)動(dong)(dong)(dong)、顯示(shi)、保護、數(shu)據采集(ji)于(yu)一體的(de)電(dian)(dian)(dian)(dian)(dian)機終端控(kong)制(zhi)(zhi)設(she)備。用(yong)戶使用(yong)較少的(de)元件，就可實(shi)(shi)現較復雜(za)的(de)控(kong)制(zhi)(zhi)功(gong)能。高壓(ya)軟起(qi)動(dong)(dong)(dong)通過控(kong)制(zhi)(zhi)晶閘(zha)管的(de)導通角對輸入電(dian)(dian)(dian)(dian)(dian)壓(ya)進(jin)行(xing)控(kong)制(zhi)(zhi)，實(shi)(shi)現改變電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機定(ding)子(zi)端電(dian)(dian)(dian)(dian)(dian)壓(ya)值(zhi)的(de)大小，即控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機的(de)起(qi)動(dong)(dong)(dong)轉(zhuan)矩和起(qi)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)流的(de)大小，從而實(shi)(shi)現電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機的(de)軟起(qi)動(dong)(dong)(dong)控(kong)制(zhi)(zhi)。高壓(ya)軟起(qi)動(dong)(dong)(dong)可按照設(she)定(ding)的(de)起(qi)動(dong)(dong)(dong)參(can)數(shu)平滑(hua)加(jia)速，從而減(jian)少對電(dian)(dian)(dian)(dian)(dian)網，電(dian)(dian)(dian)(dian)(dian)機及設(she)備的(de)電(dian)(dian)(dian)(dian)(dian)氣和機械沖擊。當電(dian)(dian)(dian)(dian)(dian)機達(da)到額定(ding)轉(zhuan)速后，旁(pang)路(lu)接(jie)觸(chu)器自動(dong)(dong)(dong)接(jie)通。高壓(ya)軟起(qi)動(dong)(dong)(dong)起(qi)動(dong)(dong)(dong)完畢(bi)后繼續監控(kong)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機，并提供各種故障保護。.
