Panyaya ye-high-voltage transmission line kuvaka, vanhu vazhinji vanoshanda pamapurojekiti vanowanzosangana neakakwira-voltage magetsi tambo majoini. Nhasi, Ndinoda kukurukura mhando dze high voltage power cable joints uye mashandisirwo awo newe. Chekutanga, ngatitaure nezvei high voltage power cable joints vari.
High Power Cable Joint
High-voltage power cable joints inoshandiswa kubatanidza tambo dzemagetsi, kusanganisira majoini uye insulated pakati majoini. Kune tambo dzemagetsi dzakazadzwa nemafuta uye tambo dzemagetsi dzisina musono, kunewo majoini eplug nemamwe majoini.
1. General joint
Inoshandiswa kubatanidza tambo dzemagetsi mbiri dziri pedyo.
Mune high-voltage simba cable nzira, kunze kwekubatanidza mugadziri wemagetsi wetambo yetambo kuti ave nechokwadi chekubatanidza midziyo yemagetsi, iyo yekubatanidza yeino-capacitating mafuta-yakazadzwa tambo yemagetsi inofanirwa kuchengetedza mutsara weoiri mupakati zvakanaka.. Asi nekuti mubatanidzwa unogadzirwa nemaoko mumunda, maitiro ayo ekugadzirisa haana kunaka. Saka, iyo yakakosha yekubatanidza pamutsetse inosarudzwa pasi peiyo riveting standard, uye iyo electrostatic field concentration dambudziko pane imwechete pick core connection inogadziriswa nekusimudzira kusimba kwekuisa uye kuderedza simba remagineti mubasa rekubatana kuti ive nechokwadi chekushanda kwakachengeteka kwejoint.. Kazhinji, iyo insulation ye-high-voltage power cables inoputirwa kumativi ekumusoro kwekuvhara kwemhepo, uye mativi maviri evhavha inomonerera inoburitsa koni-yakaita pamusoro pepasi stress cone. Iyo insulation shield yakaputirwa kunze kweiyo insulation yekubatanidza mativi maviri e power cable insulation shield. Uye mupendero wayo wekunze une pombi yekunze inopenya isina musono kuvharisa nemhepo inovharira kuitira kuti ikwanise kutakura mhute yetambo yemagetsi yakazadzwa nemafuta..
2. Insulation joint
Insulation majoini ane chimiro chakafanana uye zvinotsanangurwa sezvizhinji majoini. 110 ~ 225kV mafuta-akazadzwa nemagetsi tambo yekuvharisa majoini anoshandiswa muhombe uye pfupi simba tambo nzira. Kuitira kuti majoini ari kumativi ese emagetsi tambo yesimbi zvinhu sheath kana simbi zvinhu zvivhare padhiri uye semi-conductivity layer mumidziyo yemagetsi inoputika., kufambisa muchinjika-mhando yekubatanidza, kuderedza kunze sheath (kana kuti vhara layer) kubvaruka.
3. Plug stop type joint
Iyo plug yekumira yemhando yekubatanidza ndiyo yakanyanya kushomeka nhanho yekushanda kwemagetsi emafuta-akazadzwa nemagetsi tambo fittings uye zvakare ndiyo yakanyanya kuoma kuvaka kwejoint.. Ndiyo kiyi yekushandisa kuburitsa kupfuura kukosha kwakajairika kwehunyengeri prep reg bepa-yakavharidzirwa magetsi tambo nzira., bvisa mugero wemafuta, kudzivirira kuvharwa kwetambo dzemagetsi epamusoro-soro kuti dziome, low-end power cable insulation vapor pressure inodarika kukosha kwakajairika.
115kV one-chamber plug stop positive intermediate joint, kazhinji ne epoxy resin rabha isina mvura sleeve yekuparadzanisa mutsara wemafuta wetambo mbiri dzemagetsi.
225kV double chamber type plug stop positive intermediate joint, ine maviri epoxy resin rabha isina mvura casing kuparadzanisa mutsara wemafuta wetambo mbiri dzemagetsi, muzvikamu zvakati wandei zvesimba tambo plug yekumisa chubhu padivi repamusoro pegomba rekunze, maviri ane mukati memadziro etambo yemagetsi uye yekunze mhango yemafuta mutsara wekudyidzana, ane maviri akavharwa chimiro.
4. Seamless simbi pombi mafuta akazadzwa simba tambo majoini
Kune marudzi maviri emhepo-conditioning yemhangura chubhu mafuta-akazadzwa simba tambo majoini: general kubatana majoini uye hafu yekumisa majoini.
General connection joint, inoshandiswa pakugadzira tambo dzemagetsi uye kugadzira mapfupi uye marefu ekubatanidza, chimiro chayo chemukati chekudzivirira chinowanzofanana neiyo yega capacitative mafuta-akazadzwa magetsi matambo majoini emavara maviri, imba yayo dhayamita zvishoma kudarika simba tambo pombi yemhepo-conditioning mhangura pombi. Half plug inomira yakabatana kwenguva refu isina musono pombi inozadzwa nemagetsi tambo nzira. Ijoinhi rakagadzirirwa kudzivirira kubuda kweakawanda emagetsi tambo dzemagetsi kana tsaona yekuchengetedzwa kwemafuta yaitika uye yakagadzirirwa kupatsanura zvikamu zvemafuta zvakapihwa kuitira kuti mafuta ari muzvikamu zviviri izvi afambe nepakati pesimba rekuvhara tambo kana bypass chubhu commodity.. Mupombi yesimbi isina musono yejojo uye pombi yesimbi isina musono yekubatanidza tambo yemagetsi, iyo yekuisa chisimbiso inosarudzwa kuti iparadzanise tambo yemagetsi chiteshi chemafuta.
