隨(sui)著我(wo)國國民經濟的發展，城市建設日益繁榮(rong)，其裝飾布、線(xian)材產品(pin)的市場需求(qiu)更是旺盛。高壓(ya)(ya)電(dian)(dian)力電(dian)(dian)纜連(lian)接器用于電(dian)(dian)力電(dian)(dian)纜本(ben)身的連(lian)接。有人問(wen)高壓(ya)(ya)電(dian)(dian)力電(dian)(dian)纜的接頭(tou)有哪些？

1.普通連接器

用于(yu)(yu)連(lian)(lian)接(jie)相(xiang)鄰(lin)的(de)(de)(de)(de)(de)兩根電(dian)(dian)(dian)(dian)(dian)(dian)源線(xian)。在(zai)高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)線(xian)路中，直通(tong)(tong)連(lian)(lian)接(jie)器除了(le)連(lian)(lian)接(jie)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)芯導體以(yi)確保(bao)(bao)電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)連(lian)(lian)接(jie)外(wai)，還必須(xu)保(bao)(bao)持自容式充(chong)(chong)油電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)芯內的(de)(de)(de)(de)(de)油流(liu)連(lian)(lian)通(tong)(tong)。但(dan)是(shi)，由于(yu)(yu)連(lian)(lian)接(jie)器是(shi)在(zai)現場(chang)手動操作的(de)(de)(de)(de)(de)，其(qi)技(ji)術條件較(jiao)差。因(yin)此，在(zai)壓(ya)接(jie)線(xian)芯連(lian)(lian)接(jie)的(de)(de)(de)(de)(de)情況下(xia)，針對線(xian)芯連(lian)(lian)接(jie)處電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)集中的(de)(de)(de)(de)(de)問題，增加絕(jue)緣(yuan)(yuan)厚度以(yi)降(jiang)低(di)接(jie)頭的(de)(de)(de)(de)(de)工作場(chang)強，以(yi)保(bao)(bao)障連(lian)(lian)接(jie)器的(de)(de)(de)(de)(de)安全運行。通(tong)(tong)常，電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)絕(jue)緣(yuan)(yuan)層纏繞(rao)在(zai)絕(jue)緣(yuan)(yuan)層上，附(fu)加繞(rao)組的(de)(de)(de)(de)(de)絕(jue)緣(yuan)(yuan)層兩端形(xing)成一個錐(zhui)形(xing)表面應力錐(zhui)。絕(jue)緣(yuan)(yuan)屏蔽套(tao)在(zai)附(fu)加繞(rao)組絕(jue)緣(yuan)(yuan)的(de)(de)(de)(de)(de)外(wai)側，并連(lian)(lian)接(jie)兩端電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)絕(jue)緣(yuan)(yuan)屏蔽，外(wai)側有外(wai)光(guang)亮鋼(gang)管，將(jiang)絕(jue)緣(yuan)(yuan)與大氣(qi)隔離，使其(qi)能(neng)夠承受充(chong)(chong)油電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)油壓(ya)。

2.絕緣接頭

絕(jue)緣接頭的絕(jue)緣結構和尺寸與普通接頭相同。110～220kV充(chong)油電力電纜絕(jue)緣接頭，主要用于(yu)大長度(du)電力電纜線路，使(shi)接頭兩端電力電纜的金屬(shu)護套(tao)或金屬(shu)屏蔽(bi)(bi)層與半導電層電氣斷開，便于(yu)交叉連接，減少護套(tao)（或屏蔽(bi)(bi)）損耗。

3.插頭連接器

插(cha)頭連接器(qi)是(shi)(shi)充油(you)電(dian)(dian)力電(dian)(dian)纜(lan)(lan)附件電(dian)(dian)氣(qi)性能中(zhong)薄弱的一(yi)環(huan)，也是(shi)(shi)結構復雜的連接器(qi)。主要用于切斷壓(ya)降大(da)于規定值(zhi)的電(dian)(dian)力電(dian)(dian)纜(lan)(lan)線路中(zhong)的油(you)路，防止高壓(ya)電(dian)(dian)力電(dian)(dian)纜(lan)(lan)絕(jue)緣(yuan)(yuan)干涸(he)和低端電(dian)(dian)力電(dian)(dian)纜(lan)(lan)絕(jue)緣(yuan)(yuan)油(you)壓(ya)。超過(guo)規定值(zhi)。

110kV單室插塞(sai)式中間(jian)接(jie)頭，通(tong)常采用環氧套管隔(ge)開(kai)兩(liang)根電力電纜(lan)的油流(liu)(liu)(liu)。220kV雙腔堵(du)頭中間(jian)接(jie)頭，用兩(liang)個(ge)環氧樹脂套管隔(ge)開(kai)兩(liang)根電力電纜(lan)的油流(liu)(liu)(liu)，兩(liang)段(duan)電力電纜(lan)的堵(du)管上(shang)方有一個(ge)外腔，兩(liang)個(ge)內(nei)腔容納電力電纜(lan)一外腔與油流(liu)(liu)(liu)相通(tong)，為兩(liang)級密封結構(gou)。

4.鋼管充油電力電纜接(jie)頭

銅管(guan)(guan)充(chong)油(you)電(dian)(dian)(dian)(dian)力(li)(li)(li)(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)接(jie)(jie)頭(tou)(tou)(tou)有普通連接(jie)(jie)接(jie)(jie)頭(tou)(tou)(tou)和半插接(jie)(jie)頭(tou)(tou)(tou)兩(liang)種。普通連接(jie)(jie)接(jie)(jie)頭(tou)(tou)(tou)用(yong)于電(dian)(dian)(dian)(dian)力(li)(li)(li)(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)制造長(chang)(chang)度連接(jie)(jie)。其(qi)內絕(jue)緣結(jie)構一般與自給式充(chong)油(you)電(dian)(dian)(dian)(dian)力(li)(li)(li)(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)接(jie)(jie)頭(tou)(tou)(tou)交替，其(qi)外(wai)殼為銅管(guan)(guan)，其(qi)直徑略大(da)于電(dian)(dian)(dian)(dian)力(li)(li)(li)(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)導管(guan)(guan)的(de)(de)直徑。用(yong)于長(chang)(chang)鋼管(guan)(guan)充(chong)油(you)電(dian)(dian)(dian)(dian)力(li)(li)(li)(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)半插頭(tou)(tou)(tou)連接(jie)(jie)器。是為避免(mian)發(fa)生漏油(you)事故(gu)時大(da)量電(dian)(dian)(dian)(dian)力(li)(li)(li)(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)套(tao)管(guan)(guan)丟失而設計的(de)(de)接(jie)(jie)頭(tou)(tou)(tou)。用(yong)于將(jiang)供油(you)段隔(ge)開，使兩(liang)段油(you)液流經電(dian)(dian)(dian)(dian)力(li)(li)(li)(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)絕(jue)緣層或旁通管(guan)(guan)。在接(jie)(jie)頭(tou)(tou)(tou)鋼管(guan)(guan)與電(dian)(dian)(dian)(dian)力(li)(li)(li)(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)鋼管(guan)(guan)的(de)(de)連接(jie)(jie)處，采(cai)用(yong)密封結(jie)構將(jiang)電(dian)(dian)(dian)(dian)力(li)(li)(li)(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)油(you)路隔(ge)開。

我國(guo)有上(shang)千家(jia)高(gao)壓電力電纜生產廠家(jia)，規模和質(zhi)量各不相同，市面(mian)上(shang)家(jia)裝(zhuang)電線(xian)*也很(hen)多。對于廣大用戶來說，從眾多家(jia)裝(zhuang)線(xian)材(cai)*中挑選好的產品是一件很(hen)復雜的事(shi)情。
