Ezweni lanamuhla eliqhutshwa ubuchwepheshe, lapho ugesi uwumgogodla wezimboni eziningi, ukudluliswa okuphephile nokuphumelelayo kwamandla aphezulu kagesi (i-HV) kubalulekile. Amasokhethi ekhebula ane-voltage ephezulu adlala indima ebalulekile ekuqinisekiseni ukudluliselwa kwamandla kagesi okungenamthungo kusuka endaweni eyodwa kuya kwenye. Ake sijule kancane encazelweni kanye nomsebenzi wamasokhethi ekhebula ane-voltage ephezulu.
Funda ngezikhongozeli zekhebula ezine-voltage ephezulu:
Izitsha zekhebula ezinamandla aphezulu, eyaziwa nangokuthi izixhumi zekhebula ezine-voltage ephezulu, zenzelwe ukuqinisekisa ukudluliswa okuphephile nokuthembekile kwamandla ane-voltage ephezulu phakathi kwezintambo nemishini. Zisetshenziselwa ukuxhuma izintambo ezine-voltage ephezulu nemishini ehlukahlukene efana nama-transformer, ama-switchgear, ama-circuit breaker kanye neminye imishini kagesi esebenza emazingeni aphezulu e-voltage.
Ukubaluleka nezinzuzo:
1. Ukuphepha: Uma usebenzisa ugesi onamandla aphezulu, ukuphepha kuyinto ebaluleke kakhulu. Amasokhethi ekhebula anomthamo ophezulu aklanywe ngokufakwa kokushisa okuqinile ukuze kuncishiswe ingozi yokushaqeka kukagesi, ukushaqeka kwe-flashor kanye nama-short circuits. Ahlinzeka ngoxhumano oluphephile noluphephile, okunciphisa amathuba ezingozi nokulimala ngesikhathi sokufakwa noma ukulungiswa.
2. Ukusebenza Kahle: Amasokhethi ekhebula ane-voltage ephezulu aklanyelwe ukunciphisa ukulahleka kwamandla ngesikhathi sokudlulisa. Ngokuxhumeka okunamandla aphansi, aqinisekisa ukudluliselwa kwamandla okuhle kakhulu, andise ukusebenza kahle futhi anciphise imfucuza yamandla.
3. Ukuguquguquka nokuguquguquka: Kunezinhlobo eziningi kanye nemiklamo yama-cable sockets ane-voltage ephezulu ukuze kuhlangatshezwane nezinhlelo zokusebenza ezahlukene. Kungakhathaliseki ukuthi izindawo zangaphandle, ukufakwa komhlabathi noma ukuxhumeka kwesiteshi esincane, kune-cable socket efanelekile ene-voltage ephezulu ukuze kuhlangatshezwane nezidingo ezithile.
4. Ukuqina: Amasokhethi ekhebula anomthamo ophezulu ayakwazi ukumelana nezimo zemvelo ezinzima okuhlanganisa ukuguquguquka kwezinga lokushisa, umswakama kanye nokucindezeleka komshini. Amelana nokugqwala futhi aklanyelwe ukusetshenziswa isikhathi eside ezinhlotsheni ezidinga amandla amaningi, okuqinisekisa ukusebenza kwesikhathi eside kanye nokuthembeka.
5. Ukufakwa okusheshayo nokulula: Isokhethi yekhebula elinamandla aphezulu yenzelwe ukufakwa nokususwa kalula, ukunciphisa isikhathi sokungasebenzi ngesikhathi sokulungiswa noma ukuthuthukiswa kwesistimu. Izici zayo ezilula ukuzisebenzisa, njengezivikeli ezinemibala, izindawo zokuxhuma eziphawulwe ngokucacile kanye nezinketho zokufaka ezingenamathuluzi, zenza inqubo yokufaka ibe lula.
Umsebenzi:
Izisekelo zekhebula ze-voltage ephezulu ziqinisekisa ukuqhubeka kukagesi kanye nokuxhumeka okuphephile ekusetshenzisweni kwe-voltage ephezulu. Ziqukethe izixhumi zabesilisa nabesifazane, ngasinye sinomshini othize wokushisa kanye nezindlela zokuxhuma. Izixhumi zabesilisa zivame ukufakwa izikhonkwane zensimbi noma amatheminali, kuyilapho izixhumi zabesifazane ziqukethe izisekelo noma imikhono ehambisanayo.
Uma ikhebula le-voltage ephezulu lixhunywe ku-receiver efanele, izixhumi ziyahlangana bese zikhiywa kahle endaweni yazo. Lokhu kuqinisekisa uxhumano olungangeni moya noluvikelwe, okuvimbela ukuvuza, ukulahleka kwamandla kanye nomonakalo.
Ekuphetheni:
Izitsha zekhebula le-HVziyingxenye ebalulekile yezinhlelo zamandla ezinamandla aphezulu, ziqinisekisa ukudluliswa kwamandla ngendlela ephumelelayo ngenkathi ziqinisekisa ukuphepha. Ngokuqina kwazo, ukusebenza kahle kanye nokuguquguquka kwazo, zidlala indima ebalulekile emikhakheni ehlukahlukene njengamandla, ingqalasizinda kanye nokukhiqiza.
Ukuqonda ukubaluleka kanye nomsebenzi wama-cable sockets ane-voltage ephezulu kungasiza ochwepheshe ukuthi benze izinqumo ezinolwazi lapho bekhetha futhi befaka lezi zingxenye. Ngokubeka phambili ukuphepha, ukusebenza kahle kanye nokuqina, ama-cable sockets ane-voltage ephezulu enza umnikelo omkhulu ekudlulisweni kwamandla ane-voltage ephezulu okuthembekile nokungaphazanyiswa.
