高(gao)压电(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)缆(lan)连(lian)(lian)接(jie)(jie)(jie)头(tou)(tou)用于电(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)缆(lan)自(zi)身的连(lian)(lian)接(jie)(jie)(jie)，有连(lian)(lian)接(jie)(jie)(jie)接(jie)(jie)(jie)头(tou)(tou)、绝(jue)缘中心(xin)接(jie)(jie)(jie)头(tou)(tou)，对(dui)充油电(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)缆(lan)及(ji)钢管电(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)缆(lan)还有塞止式接(jie)(jie)(jie)优等。

1.通俗连接头

它(ta)用于连(lian)接两根相邻(lin)电力电缆。

在高压电(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)缆(lan)(lan)线(xian)路中，纵贯接(jie)头(tou)除(chu)连(lian)(lian)接(jie)缆(lan)(lan)芯(xin)(xin)导体保证电(dian)(dian)(dian)(dian)气连(lian)(lian)通(tong)外，对自(zi)容式充油(you)电(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)缆(lan)(lan)的(de)连(lian)(lian)接(jie)头(tou)保持(chi)线(xian)芯(xin)(xin)中油(you)流通(tong)顺。但因连(lian)(lian)接(jie)头(tou)是(shi)在现场手工(gong)操作，其(qi)工(gong)艺条(tiao)(tiao)件差。因而在线(xian)芯(xin)(xin)连(lian)(lian)接(jie)采用压接(jie)条(tiao)(tiao)件下，对线(xian)芯(xin)(xin)连(lian)(lian)接(jie)处电(dian)(dian)(dian)(dian)场集中题目的(de)处理，通(tong)过增长绝(jue)(jue)(jue)缘厚度，以此降低接(jie)头(tou)工(gong)作场强来确(que)保连(lian)(lian)接(jie)头(tou)的(de)安全运行。通(tong)常是(shi)在电(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)缆(lan)(lan)绝(jue)(jue)(jue)缘上面绕包增绕绝(jue)(jue)(jue)缘，增绕绝(jue)(jue)(jue)缘的(de)两(liang)端形成锥形面应力(li)锥。在增绕绝(jue)(jue)(jue)缘表(biao)面绕包绝(jue)(jue)(jue)缘屏蔽(bi)，将两(liang)端电(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)缆(lan)(lan)绝(jue)(jue)(jue)缘屏蔽(bi)相(xiang)连(lian)(lian)，而其(qi)表(biao)面有一外亮钢管把绝(jue)(jue)(jue)缘与(yu)大(da)气隔绝(jue)(jue)(jue)，如许即可承受(shou)充油(you)电(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)缆(lan)(lan)的(de)油(you)压。

2.绝缘接头

绝缘(yuan)接(jie)头内(nei)绝缘(yuan)结(jie)构和尺寸与通(tong)俗接(jie)头雷同。110 ~ 220kV充油电(dian)力(li)电(dian)缆绝缘(yuan)接(jie)头，重(zhong)要用于大长度电(dian)力(li)电(dian)缆线(xian)路中，使(shi)接(jie)头两(liang)端电(dian)力(li)电(dian)缆的金属(shu)(shu)护(hu)套或金属(shu)(shu)屏蔽层及半导电(dian)层在电(dian)气(qi)上断开，以(yi)便交叉互连，削减护(hu)层(或屏蔽层〉损(sun)耗。

3.塞止式接头

塞止式(shi)接头(tou)是充油(you)(you)电(dian)力电(dian)缆附件电(dian)性能微(wei)弱的环节，也是结构复杂(za)的接头(tou)。它重要用于落差(cha)大于规定值的黠(xia)性浸渍纸绝(jue)缘(yuan)电(dian)力电(dian)缆线路中(zhong)，截断油(you)(you)路，防止电(dian)力电(dian)缆绝(jue)缘(yuan)干枯、低端电(dian)力电(dian)缆绝(jue)缘(yuan)油(you)(you)压超过规定值。

110kV单室(shi)式塞止中(zhong)心接(jie)头，通常用一个环氧(yang)树脂套管将两根电力(li)电缆的油(you)流分(fen)开。

220kV双室式塞(sai)止中心接头(tou)，用两(liang)(liang)(liang)个环氧(yang)树脂(zhi)套(tao)管(guan)将两(liang)(liang)(liang)根电(dian)力(li)(li)电(dian)缆的油流分开，在(zai)两(liang)(liang)(liang)段(duan)电(dian)力(li)(li)电(dian)缆的塞(sai)止管(guan)上面有(you)一外腔(qiang)，两(liang)(liang)(liang)个含有(you)电(dian)力(li)(li)电(dian)缆的内腔(qiang)及(ji)一个外腔(qiang)油流雷(lei)同，呈两(liang)(liang)(liang)道密(mi)封结构。

4.钢管(guan)充油电(dian)力电(dian)缆接头(tou)

铜(tong)管(guan)充油电力电缆接(jie)头(tou)有通俗连接(jie)接(jie)头(tou)和(he)半(ban)塞止接(jie)头(tou)两种(zhong)。

通俗连接(jie)(jie)接(jie)(jie)头(tou)(tou)(tou)，用于电(dian)(dian)(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)(dian)(dian)缆(lan)制(zhi)造(zao)(zao)长度(du)连接(jie)(jie)，它的(de)(de)(de)内绝(jue)(jue)缘结(jie)构一(yi)样平常与自容式充(chong)油电(dian)(dian)(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)(dian)(dian)缆(lan)接(jie)(jie)头(tou)(tou)(tou)相间(jian)，其外(wai)壳(qiao)是(shi)(shi)一(yi)个直径稍大于电(dian)(dian)(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)(dian)(dian)缆(lan)管(guan)道的(de)(de)(de)铜管(guan)。半(ban)塞止(zhi)接(jie)(jie)头(tou)(tou)(tou)，用于较长的(de)(de)(de)钢管(guan)充(chong)油电(dian)(dian)(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)(dian)(dian)缆(lan)线(xian)路(lu)。它是(shi)(shi)为(wei)避(bi)免一(yi)旦发(fa)生(sheng)漏油事(shi)故造(zao)(zao)成大量(liang)电(dian)(dian)(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)(dian)(dian)缆(lan)袖的(de)(de)(de)流失(shi)而设(she)计(ji)的(de)(de)(de)接(jie)(jie)头(tou)(tou)(tou)，用来分隔供(gong)油区段(duan)，使两区段(duan)的(de)(de)(de)油经(jing)过电(dian)(dian)(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)(dian)(dian)缆(lan)绝(jue)(jue)缘层(ceng)或旁(pang)路(lu)管(guan)流通。在接(jie)(jie)头(tou)(tou)(tou)的(de)(de)(de)钢管(guan)与电(dian)(dian)(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)(dian)(dian)缆(lan)钢管(guan)连接(jie)(jie)处，采用密封结(jie)构把电(dian)(dian)(dian)(dian)(dian)(dian)力(li)电(dian)(dian)(dian)(dian)(dian)(dian)缆(lan)油路(lu)分开。
