廣東萬瑞通電纜講解高壓電力電纜連接(jie)頭種(zhong)類(lei)有什么

高(gao)壓電力(li)電纜連(lian)(lian)接(jie)(jie)頭(tou)用(yong)于電力(li)電纜自(zi)身的(de)連(lian)(lian)接(jie)(jie)，有連(lian)(lian)接(jie)(jie)接(jie)(jie)頭(tou)、絕緣中(zhong)心接(jie)(jie)頭(tou)，對充油電力(li)電纜及(ji)鋼管電力(li)電纜還有塞止(zhi)式接(jie)(jie)優(you)等。

1.通俗連接頭

它用于連接兩根相鄰電力電纜。

在高壓電(dian)力(li)(li)電(dian)纜(lan)(lan)(lan)線路中(zhong)，縱(zong)貫接(jie)(jie)(jie)(jie)頭(tou)(tou)除連接(jie)(jie)(jie)(jie)纜(lan)(lan)(lan)芯導體保(bao)(bao)證電(dian)氣連通(tong)(tong)外，對自容(rong)式充(chong)油電(dian)力(li)(li)電(dian)纜(lan)(lan)(lan)的連接(jie)(jie)(jie)(jie)頭(tou)(tou)保(bao)(bao)持線芯中(zhong)油流通(tong)(tong)順。但因連接(jie)(jie)(jie)(jie)頭(tou)(tou)是在現場手工(gong)操作，其(qi)工(gong)藝(yi)條件差。因而(er)在線芯連接(jie)(jie)(jie)(jie)采用壓接(jie)(jie)(jie)(jie)條件下，對線芯連接(jie)(jie)(jie)(jie)處(chu)電(dian)場集中(zhong)題目的處(chu)理，通(tong)(tong)過增(zeng)長(chang)絕(jue)緣(yuan)(yuan)厚度，以此降低接(jie)(jie)(jie)(jie)頭(tou)(tou)工(gong)作場強來確保(bao)(bao)連接(jie)(jie)(jie)(jie)頭(tou)(tou)的安全運行。通(tong)(tong)常是在電(dian)力(li)(li)電(dian)纜(lan)(lan)(lan)絕(jue)緣(yuan)(yuan)上(shang)面(mian)繞(rao)(rao)(rao)包增(zeng)繞(rao)(rao)(rao)絕(jue)緣(yuan)(yuan)，增(zeng)繞(rao)(rao)(rao)絕(jue)緣(yuan)(yuan)的兩端(duan)形成(cheng)錐(zhui)形面(mian)應力(li)(li)錐(zhui)。在增(zeng)繞(rao)(rao)(rao)絕(jue)緣(yuan)(yuan)表(biao)面(mian)繞(rao)(rao)(rao)包絕(jue)緣(yuan)(yuan)屏蔽(bi)，將兩端(duan)電(dian)力(li)(li)電(dian)纜(lan)(lan)(lan)絕(jue)緣(yuan)(yuan)屏蔽(bi)相連，而(er)其(qi)表(biao)面(mian)有一外亮鋼(gang)管把絕(jue)緣(yuan)(yuan)與大氣隔絕(jue)，如許即可承受充(chong)油電(dian)力(li)(li)電(dian)纜(lan)(lan)(lan)的油壓。

2.絕緣接頭

絕緣接(jie)頭內絕緣結構和尺(chi)寸(cun)與通俗接(jie)頭雷(lei)同。110 ~ 220kV充油電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)絕緣接(jie)頭，重要用于(yu)大(da)長度電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)線路中，使接(jie)頭兩端電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)的(de)金屬護(hu)套或金屬屏(ping)蔽層及半(ban)導電(dian)(dian)(dian)層在電(dian)(dian)(dian)氣上斷(duan)開，以便(bian)交叉(cha)互連，削減護(hu)層(或屏(ping)蔽層〉損耗。

3.塞止式接頭

塞止(zhi)式接頭是充油電(dian)力(li)電(dian)纜(lan)附(fu)件電(dian)性能微弱的環節，也是結(jie)構復雜(za)的接頭。它重要(yao)用于落差大(da)于規定值(zhi)的黠性浸漬紙絕(jue)緣電(dian)力(li)電(dian)纜(lan)線路(lu)中，截斷油路(lu)，防止(zhi)電(dian)力(li)電(dian)纜(lan)絕(jue)緣干枯、低端(duan)電(dian)力(li)電(dian)纜(lan)絕(jue)緣油壓超過規定值(zhi)。

110kV單室式塞止(zhi)中心(xin)接頭，通常用一個(ge)環氧樹脂(zhi)套管(guan)將兩(liang)根電(dian)力(li)電(dian)纜的油流分(fen)開。

220kV雙(shuang)室式塞止中心接頭，用兩(liang)個環(huan)氧(yang)樹脂套管將兩(liang)根電力電纜的(de)油流(liu)分(fen)開，在兩(liang)段電力電纜的(de)塞止管上面有一(yi)外(wai)腔(qiang)，兩(liang)個含有電力電纜的(de)內腔(qiang)及一(yi)個外(wai)腔(qiang)油流(liu)雷(lei)同，呈兩(liang)道密封結構。

4.鋼管充(chong)油電力電纜(lan)接頭(tou)

銅管(guan)充油電力電纜接(jie)頭有通俗(su)連(lian)接(jie)接(jie)頭和半塞(sai)止接(jie)頭兩種(zhong)。

通俗連接(jie)接(jie)頭，用于(yu)電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)制造(zao)長度(du)連接(jie)，它(ta)的(de)(de)內絕緣(yuan)結(jie)構(gou)一(yi)樣(yang)平常(chang)與(yu)自容(rong)式充油(you)(you)電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)接(jie)頭相間，其外殼是一(yi)個直(zhi)徑稍大于(yu)電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)管道的(de)(de)銅管。半塞止接(jie)頭，用于(yu)較長的(de)(de)鋼(gang)管充油(you)(you)電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)線路。它(ta)是為(wei)避免(mian)一(yi)旦發(fa)生漏油(you)(you)事故造(zao)成大量電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)袖的(de)(de)流失而設計(ji)的(de)(de)接(jie)頭，用來分隔供油(you)(you)區(qu)段，使兩(liang)區(qu)段的(de)(de)油(you)(you)經(jing)過電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)絕緣(yuan)層或旁路管流通。在接(jie)頭的(de)(de)鋼(gang)管與(yu)電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)鋼(gang)管連接(jie)處，采(cai)用密封結(jie)構(gou)把電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)油(you)(you)路分開。
