1.全部元(yuan)器件(jian)(jian)應依照其生產制造要求的安裝(zhuang)應用(yong)標準開(kai)展安裝(zhuang)應用(yong),其坡(po)度不超5°,務必確保(bao)電氣設備的飛弧對(dui)作業(ye)者以及他元(yuan)器件(jian)(jian)不造成傷(shang)害,手(shou)動式實際操(cao)作的元(yuan)器件(jian)(jian),實際操(cao)作組織(zhi)應靈便(bian),無卡阻(zu)狀況。
2.大連高低壓開關柜產(chan)品上(shang)的全部顯示燈和按(an)鍵(jian)規格(ge)型(xing)號顏(yan)色應合(he)乎電路原(yuan)理圖或(huo)接線方法(fa)的要求(qiu)。
3.元器(qi)件務必(bi)選用獲得強制產(chan)品認證的廠家生(sheng)產(chan)的達(da)標產(chan)品,非認證產(chan)品不可應(ying)用。
4.大連(lian)高低壓開關柜產品(pin)內挑選(xuan)的(de)(de)電氣元(yuan)器件和(he)原材料,務必(bi)合(he)乎(hu)認證(zheng)產品(pin)規(gui)(gui)定和(he)消(xiao)費者工程圖紙的(de)(de)規(gui)(gui)定,不在危害產品(pin)本質(zhi)品(pin)質(zhi)規(gui)(gui)定的(de)(de)前提條件下,能(neng)夠 征求有關準許開展(zhan)認證(zheng)要(yao)求范疇(chou)內的(de)(de)代用。但同(tong)批成套設備產品(pin)的(de)(de)同(tong)一(yi)型號規(gui)(gui)格元(yuan)器件應挑選(xuan)同(tong)一(yi)生產廠家。
異(yi)步(bu)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機的(de)(de)定(ding)(ding)(ding)子(zi)(zi)繞(rao)組(zu)是嵌人定(ding)(ding)(ding)子(zi)(zi)鐵芯槽內的(de)(de),定(ding)(ding)(ding)子(zi)(zi)繞(rao)組(zu)的(de)(de)匝間以及定(ding)(ding)(ding)子(zi)(zi)繞(rao)組(zu)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機機座(zuo)之間均存在分(fen)布電(dian)(dian)(dian)(dian)(dian)(dian)容,當(dang)通用變(bian)頻(pin)器在高載頻(pin)下(xia)運行(xing)時,逆變(bian)器的(de)(de)共(gong)模電(dian)(dian)(dian)(dian)(dian)(dian)壓產(chan)生急(ji)劇變(bian)化(hua),會通過電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機繞(rao)組(zu)的(de)(de)分(fen)布電(dian)(dian)(dian)(dian)(dian)(dian)容由(you)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機的(de)(de)外殼(ke)到接地(di)端(duan)之間形成(cheng)漏電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)。電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機采用逆變(bian)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)運行(xing)時,供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓含有高次諧波(bo)分(fen)量,使定(ding)(ding)(ding)子(zi)(zi)繞(rao)組(zu)線(xian)圈端(duan)部、接線(xian)部分(fen)、轉軸之間產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)感(gan)應(ying)從而產(chan)生軸電(dian)(dian)(dian)(dian)(dian)(dian)壓。該漏電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)有可能形成(cheng)放射性和(he)傳導性兩類電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)干擾(rao)。而由(you)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機磁(ci)路的(de)(de)不平衡,靜電(dian)(dian)(dian)(dian)(dian)(dian)感(gan)應(ying)和(he)共(gong)模電(dian)(dian)(dian)(dian)(dian)(dian)壓又是產(chan)生軸電(dian)(dian)(dian)(dian)(dian)(dian)壓和(he)軸電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)起因。
