Kwihlabathi lanamhlanje eliqhutywa bubuchwephesha, apho umbane ungoyena ndoqo kumashishini amaninzi, ukuhanjiswa okukhuselekileyo nokuphumelela kwamandla ombane aphezulu (HV) kubalulekile. Iziseko zeentambo zombane ophezulu zidlala indima ephambili ekuqinisekiseni ukuhanjiswa kwamandla ombane ngaphandle komthungo ukusuka kwenye indawo ukuya kwenye. Masimbe nzulu kancinci kwintsingiselo kunye nomsebenzi wesokethi zentambo zombane ophezulu.
Funda malunga nezixhobo zentambo zombane ophezulu:
Izixhobo zentambo zombane ophezulu, eyaziwa ngokuba yi-high-voltage cable connectors, yenzelwe ukuqinisekisa ukuhanjiswa okukhuselekileyo nokuthembekileyo kwamandla aphezulu ombane phakathi kweentambo kunye nezixhobo. Zisetyenziselwa ukudibanisa iintambo zombane ophezulu kwizixhobo ezahlukeneyo ezifana neziguquli, ii-switchgear, izaphuli zesekethe kunye nezinye izixhobo zombane ezisebenza kumanqanaba ombane aphezulu.
Ukubaluleka kunye neenzuzo:
1. Ukhuseleko: Xa usebenzisa i-high-voltage power supply, ukhuseleko lolona qwalaselo luphambili. Iisokethi zentambo zombane ophezulu ziyilwe ngokugquma okomelele ukuze kuncitshiswe umngcipheko wokothuka kombane, i-flashover kunye neesekethe ezimfutshane. Banikezela uxhulumaniso olukhuselekileyo nolukhuselekileyo, ukunciphisa ithuba leengozi kunye nokulimala ngexesha lofakelo okanye ukulungiswa.
2. Ukusebenza kakuhle: Iisokethi zentambo zombane eziphezulu zenzelwe ukunciphisa ukulahleka kwamandla ngexesha lokuhambisa. Ngoxhumo oluphantsi lokumelana, baqinisekisa ukugqithiswa kwamandla afanelekileyo, ukwandisa ukusebenza kakuhle kunye nokunciphisa inkunkuma yamandla.
3. Ukuguquguquka kunye nokuguquguquka: Kukho iintlobo ezininzi kunye noyilo lweesokethi zentambo zombane ophezulu ukuhlangabezana nezicelo ezahlukeneyo. Nokuba ziimeko ezingqongileyo zangaphandle, ufakelo oluphantsi komhlaba okanye uqhagamshelo lwesikhululo esingaphantsi, kukho isokethi yentambo yombane ophezulu ofanelekileyo ukuhlangabezana neemfuno ezithile.
4. Ukuqina: Iisokethi zentambo zombane ophezulu ziyakwazi ukumelana neemeko ezirhabaxa zokusingqongileyo ezibandakanya ukuguquguquka kobushushu, ukufuma kunye noxinzelelo lomatshini. Ziyi-resistant-resistant kwaye zenzelwe ukusetyenziswa kwexesha elide kwizicelo ezifunwayo, ziqinisekisa ukusebenza kwexesha elide kunye nokuthembeka.
5. Ufakelo olukhawulezayo nolulula: Isokhethi yekhebula ephezulu ye-voltage yenzelwe ukufakwa lula kunye nokususwa, ukunciphisa ixesha lokunciphisa ngexesha lokugcinwa okanye ukuphuculwa kwenkqubo. Iimpawu zayo ezisebenzisekayo, ezifana ne-insulators ezinombala, amanqaku okudibanisa aphawulwe ngokucacileyo kunye nezixhobo zokufakela izixhobo ezingaphantsi, ukwenza lula inkqubo yokufakela.
Umsebenzi:
Iziseko zeentambo zombane ophezulu ziqinisekisa ukuqhubeka kombane kunye noqhagamshelo olukhuselekileyo kwizicelo zombane ophezulu. Ziquka izihlanganisi zamadoda nabasetyhini, nganye ine-insulation ethile kunye neendlela zokudibanisa. Izixhumi zamadoda zidla ngokuxhotyiswa ngezikhonkwane zetsimbi okanye iitheminali, ngelixa izihlanganisi zabasetyhini ziquka iisokethi ezihambelanayo okanye imikhono.
Xa intambo yamandla ombane aphezulu iqhagamshelwe kummkeli ofanelekileyo, iziqhagamshelo zijolisa kwaye zitshixe ngokukhuselekileyo endaweni. Oku kuqinisekisa uxhulumaniso olungangeni moya kunye ne-insulated, ukuthintela ukuvuza, ukulahleka kwamandla kunye nomonakalo.
ukuququmbela:
Izixhobo zentambo zeHVziyinxalenye ebalulekileyo yeenkqubo zamandla ombane aphezulu, ziqinisekisa ukuhanjiswa kwamandla ngokufanelekileyo ngelixa uqinisekisa ukhuseleko. Ngokuhlala kwabo, ukusebenza kakuhle kunye nokuguquguquka, badlala indima ebalulekileyo kwiinkalo ezahlukeneyo ezifana namandla, iziseko zophuhliso kunye nokuvelisa.
Ukuqonda ukubaluleka kunye nomsebenzi weesokethi zentambo zombane ophezulu kunokunceda iingcali ukuba zenze izigqibo ezinolwazi xa zikhetha kwaye zifakela la macandelo. Ngokubeka phambili ukhuseleko, ukusebenza kakuhle kunye nokuqina, iisokethi zentambo zombane ophezulu zenza igalelo elibalulekileyo ekuhanjisweni okuthembekileyo kunye nokungaphazanyiswa kwamandla ombane aphezulu.
