變頻器自動切換柜也叫做一拖一自(zi)(zi)動旁(pang)(pang)路柜，性(xing)能滿足GB3906、IEC298等標準要(yao)求(qiu)，具有防止誤(wu)分合斷路器(qi)、接觸器(qi)、隔離開關等、防止誤(wu)入帶電隔室等“五防”聯(lian)鎖功能。可配用(yong)真空(kong)(kong)斷路器(qi)，又可配用(yong)真空(kong)(kong)接觸器(qi)實現(xian)自(zi)(zi)動旁(pang)(pang)路方(fang)案，那么能用(yong)隔離開關實現(xian)手(shou)動旁(pang)(pang)路方(fang)案嗎？

變(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)(qi)一次回路由3個高(gao)(gao)(gao)壓真空接(jie)觸(chu)器(qi)(qi)(qi)(qi)K1、K2、KM和2個高(gao)(gao)(gao)壓隔(ge)離(li)開關(guan)(guan)(guan)(guan)QS1、QS2組成。高(gao)(gao)(gao)壓電(dian)(dian)源(yuan)經(jing)高(gao)(gao)(gao)壓隔(ge)離(li)開關(guan)(guan)(guan)(guan)QS1、真空接(jie)觸(chu)器(qi)(qi)(qi)(qi)K1到高(gao)(gao)(gao)壓變(bian)(bian)頻(pin)(pin)裝置，變(bian)(bian)頻(pin)(pin)裝置輸出經(jing)真空接(jie)觸(chu)器(qi)(qi)(qi)(qi)K2、高(gao)(gao)(gao)壓隔(ge)離(li)開關(guan)(guan)(guan)(guan)QS2送(song)至(zhi)電(dian)(dian)動(dong)機(ji)，電(dian)(dian)動(dong)機(ji)變(bian)(bian)頻(pin)(pin)運(yun)行(xing)；高(gao)(gao)(gao)壓電(dian)(dian)源(yuan)還可經(jing)真空接(jie)觸(chu)器(qi)(qi)(qi)(qi)KM直(zhi)接(jie)起動(dong)電(dian)(dian)動(dong)機(ji)，電(dian)(dian)動(dong)機(ji)工(gong)頻(pin)(pin)運(yun)行(xing)。KM與K2電(dian)(dian)氣閉鎖，保(bao)證(zheng)(zheng)任何時(shi)候不能(neng)同時(shi)合閘。隔(ge)離(li)開關(guan)(guan)(guan)(guan)QS1、QS2作用是：隔(ge)離(li)變(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)(qi)以保(bao)證(zheng)(zheng)在工(gong)頻(pin)(pin)進(jin)行(xing)時(shi)維(wei)護(hu)變(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)(qi)，保(bao)證(zheng)(zheng)維(wei)護(hu)人員安全。非(fei)維(wei)護(hu)期兩個隔(ge)離(li)開關(guan)(guan)(guan)(guan)處于閉合狀態；高(gao)(gao)(gao)壓開關(guan)(guan)(guan)(guan)QF1與電(dian)(dian)動(dong)機(ji)為原有(you)設備(bei)。優點是在變(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)(qi)出現嚴重故障時(shi)，系統(tong)能(neng)夠自動(dong)轉入工(gong)頻(pin)(pin)電(dian)(dian)網(wang)中，斷開變(bian)(bian)頻(pin)(pin)調速(su)系統(tong)時(shi)，而負載不需要停機(ji)，滿足現場不能(neng)停機(ji)的要求。
