在(zai)(zai)變(bian)頻電(dian)機電(dian)纜(lan)生產過程(cheng)中(zhong)(zhong)，絕(jue)緣(yuan)(yuan)(yuan)(yuan)線芯(xin)擠包工(gong)序(xu)、成纜(lan)工(gong)序(xu)等是(shi)關鍵的工(gong)序(xu)。絕(jue)緣(yuan)(yuan)(yuan)(yuan)線芯(xin)擠包工(gong)序(xu)絕(jue)緣(yuan)(yuan)(yuan)(yuan)線芯(xin)的質(zhi)量將直接影響到(dao)電(dian)纜(lan)的電(dian)氣(qi)性能。為了提高電(dian)纜(lan)的質(zhi)量，我們(men)選擇高電(dian)性能絕(jue)緣(yuan)(yuan)(yuan)(yuan)材(cai)料生產，例如1.8/3kv變(bian)頻電(dian)機電(dian)纜(lan)，采(cai)用(yong)(yong)10kV交聯(lian)絕(jue)緣(yuan)(yuan)(yuan)(yuan)材(cai)料，6/10kv變(bian)頻電(dian)機電(dian)纜(lan)采(cai)用(yong)(yong)35kv交聯(lian)絕(jue)緣(yuan)(yuan)(yuan)(yuan)材(cai)料，導體屏(ping)蔽、絕(jue)緣(yuan)(yuan)(yuan)(yuan)屏(ping)蔽和絕(jue)緣(yuan)(yuan)(yuan)(yuan)材(cai)料均采(cai)用(yong)(yong)了進口材(cai)料。在(zai)(zai)生產過程(cheng)中(zhong)(zhong)，特別注(zhu)重原材(cai)料的凈化(hua)，屏(ping)蔽與(yu)絕(jue)緣(yuan)(yuan)(yuan)(yuan)材(cai)料擠包緊密，控(kong)制絕(jue)緣(yuan)(yuan)(yuan)(yuan)偏心度和絕(jue)緣(yuan)(yuan)(yuan)(yuan)外(wai)徑的均勻一致，這(zhe)樣可減少界面效(xiao)應，提高電(dian)纜(lan)電(dian)氣(qi)性能。
變頻(pin)裝置的(de)節(jie)(jie)能效(xiao)果(guo)十分(fen)明(ming)顯，在大功率電(dian)(dian)機中采用(yong)變頻(pin)調速(su)電(dian)(dian)機，整個(ge)發(fa)電(dian)(dian)機組可節(jie)(jie)電(dian)(dian)30%。并(bing)且(qie)使(shi)用(yong)變頻(pin)調速(su)后(hou)，實現了(le)(le)電(dian)(dian)機的(de)軟啟動，使(shi)電(dian)(dian)機工作平穩，電(dian)(dian)機軸承磨損減(jian)小(xiao)，延長了(le)(le)電(dian)(dian)機使(shi)用(yong)壽命(ming)和維(wei)護周期。因此，變頻(pin)調速(su)技術在石油、冶(ye)金、發(fa)電(dian)(dian)、鐵路、礦山(shan)等工業(ye)方面得(de)到了(le)(le)廣泛的(de)使(shi)用(yong)。
