广东万瑞通电缆讲解(jie)高(gao)压电力电缆连接头种类有什么

高压电(dian)(dian)(dian)(dian)力(li)(li)电(dian)(dian)(dian)(dian)缆连(lian)接(jie)头(tou)(tou)用于电(dian)(dian)(dian)(dian)力(li)(li)电(dian)(dian)(dian)(dian)缆自身的连(lian)接(jie)，有连(lian)接(jie)接(jie)头(tou)(tou)、绝缘中心接(jie)头(tou)(tou)，对充油电(dian)(dian)(dian)(dian)力(li)(li)电(dian)(dian)(dian)(dian)缆及钢管电(dian)(dian)(dian)(dian)力(li)(li)电(dian)(dian)(dian)(dian)缆还有塞(sai)止式接(jie)优等。

1.通俗连接头

它用于(yu)连接两(liang)根相邻电力电缆(lan)。

在(zai)高压电(dian)(dian)(dian)力(li)(li)电(dian)(dian)(dian)缆(lan)(lan)线(xian)路(lu)中，纵贯接(jie)(jie)头(tou)除连接(jie)(jie)缆(lan)(lan)芯导体保证(zheng)电(dian)(dian)(dian)气(qi)(qi)连通(tong)外(wai)(wai)，对(dui)自容式充(chong)油(you)电(dian)(dian)(dian)力(li)(li)电(dian)(dian)(dian)缆(lan)(lan)的(de)(de)连接(jie)(jie)头(tou)保持线(xian)芯中油(you)流通(tong)顺。但因(yin)连接(jie)(jie)头(tou)是在(zai)现(xian)场手工(gong)操作(zuo)，其工(gong)艺(yi)条件差。因(yin)而在(zai)线(xian)芯连接(jie)(jie)采用压接(jie)(jie)条件下，对(dui)线(xian)芯连接(jie)(jie)处(chu)电(dian)(dian)(dian)场集(ji)中题目的(de)(de)处(chu)理，通(tong)过(guo)增(zeng)长绝缘厚(hou)度，以此降(jiang)低接(jie)(jie)头(tou)工(gong)作(zuo)场强来确(que)保连接(jie)(jie)头(tou)的(de)(de)安全运行。通(tong)常是在(zai)电(dian)(dian)(dian)力(li)(li)电(dian)(dian)(dian)缆(lan)(lan)绝缘上面绕(rao)(rao)包(bao)增(zeng)绕(rao)(rao)绝缘，增(zeng)绕(rao)(rao)绝缘的(de)(de)两端形成锥形面应力(li)(li)锥。在(zai)增(zeng)绕(rao)(rao)绝缘表(biao)面绕(rao)(rao)包(bao)绝缘屏(ping)蔽，将(jiang)两端电(dian)(dian)(dian)力(li)(li)电(dian)(dian)(dian)缆(lan)(lan)绝缘屏(ping)蔽相连，而其表(biao)面有一外(wai)(wai)亮(liang)钢管把绝缘与(yu)大气(qi)(qi)隔(ge)绝，如许(xu)即可承受充(chong)油(you)电(dian)(dian)(dian)力(li)(li)电(dian)(dian)(dian)缆(lan)(lan)的(de)(de)油(you)压。

2.绝缘接头

绝(jue)缘接头内(nei)绝(jue)缘结构(gou)和(he)尺寸(cun)与通俗接头雷同。110 ~ 220kV充油(you)电(dian)(dian)力(li)电(dian)(dian)缆绝(jue)缘接头，重要用于大(da)长度(du)电(dian)(dian)力(li)电(dian)(dian)缆线路中，使(shi)接头两端电(dian)(dian)力(li)电(dian)(dian)缆的金属护套或金属屏蔽层及半导(dao)电(dian)(dian)层在(zai)电(dian)(dian)气上断开，以(yi)便交叉互连，削减(jian)护层(或屏蔽层〉损耗。

3.塞止式接头

塞止(zhi)式接头(tou)是(shi)(shi)充油(you)电(dian)(dian)力电(dian)(dian)缆附件电(dian)(dian)性能(neng)微弱的(de)(de)环节，也是(shi)(shi)结构复杂的(de)(de)接头(tou)。它(ta)重(zhong)要用(yong)于落差大于规定值(zhi)的(de)(de)黠(xia)性浸渍纸绝缘电(dian)(dian)力电(dian)(dian)缆线路(lu)中(zhong)，截断油(you)路(lu)，防(fang)止(zhi)电(dian)(dian)力电(dian)(dian)缆绝缘干(gan)枯、低(di)端电(dian)(dian)力电(dian)(dian)缆绝缘油(you)压超过规定值(zhi)。

110kV单室式塞止中心接头，通常用(yong)一个环(huan)氧(yang)树(shu)脂套管将两根电力电缆(lan)的油(you)流分(fen)开。

220kV双室式塞(sai)(sai)止(zhi)中心接头，用两个(ge)环(huan)氧树脂(zhi)套管将两根电(dian)力电(dian)缆(lan)(lan)的油流分开，在两段(duan)电(dian)力电(dian)缆(lan)(lan)的塞(sai)(sai)止(zhi)管上面(mian)有(you)一(yi)外(wai)腔，两个(ge)含(han)有(you)电(dian)力电(dian)缆(lan)(lan)的内腔及(ji)一(yi)个(ge)外(wai)腔油流雷同，呈两道密封结构。

4.钢管充油电(dian)力电(dian)缆接头

铜管(guan)充油电力电缆(lan)接(jie)头(tou)有通(tong)俗连接(jie)接(jie)头(tou)和半塞止接(jie)头(tou)两种。

通(tong)俗(su)连接(jie)接(jie)头(tou)，用(yong)(yong)于电(dian)(dian)(dian)(dian)力(li)(li)(li)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)制(zhi)造长度连接(jie)，它的(de)内绝缘(yuan)结(jie)构一样(yang)平常与(yu)自容(rong)式充(chong)油(you)(you)电(dian)(dian)(dian)(dian)力(li)(li)(li)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)接(jie)头(tou)相间，其外壳是一个直径稍大于电(dian)(dian)(dian)(dian)力(li)(li)(li)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)管道的(de)铜管。半塞止接(jie)头(tou)，用(yong)(yong)于较长的(de)钢(gang)(gang)管充(chong)油(you)(you)电(dian)(dian)(dian)(dian)力(li)(li)(li)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)线路。它是为避免(mian)一旦(dan)发生漏油(you)(you)事故造成(cheng)大量电(dian)(dian)(dian)(dian)力(li)(li)(li)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)袖的(de)流(liu)失(shi)而设计(ji)的(de)接(jie)头(tou)，用(yong)(yong)来分(fen)隔供油(you)(you)区段，使两区段的(de)油(you)(you)经过电(dian)(dian)(dian)(dian)力(li)(li)(li)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)绝缘(yuan)层或旁(pang)路管流(liu)通(tong)。在(zai)接(jie)头(tou)的(de)钢(gang)(gang)管与(yu)电(dian)(dian)(dian)(dian)力(li)(li)(li)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)钢(gang)(gang)管连接(jie)处，采用(yong)(yong)密封结(jie)构把电(dian)(dian)(dian)(dian)力(li)(li)(li)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)油(you)(you)路分(fen)开。
