Isingeniso kumabhokisi egatsha lekhebula

Imisebenzi Eyinhloko 

Amabhokisi egatsha lekhebulakufeza izinjongo ezimbili eziyinhloko ekuphathweni kwegridi:

Ukwehlukaniswa Kwekhebula:Emigqeni kagesi ekude, ukusebenzisa ikhebula eliyinhloko elilodwa elinomthamo omkhulu kuyonga kakhulu kunokusebenzisa izintambo eziningi ezincane. Njengoba umugqa usondela endaweni yokusetshenziswa (isb., indawo yokuhlala noma isikhungo sezentengiselwano), ibhokisi legatsha lisetshenziselwa ukuhlukanisa ikhebula eliyinhloko libe izintambo eziningana ezincane ezixhunywe emithwalweni ngayinye, njengezibani zomgwaqo noma izakhiwo.

Ukuxhumeka Kwekhebula (I-Junction):Uma umzila wekhebula umude kunobude bekhebula elilodwa elijwayelekile, kudingeka indawo yokuxhuma. Kumabanga amafushane, kusetshenziswa ijoyinti elisemgqeni. Kodwa-ke, emizileni emide (isb., ngaphezu kwamamitha ayi-1000), ukusebenzisa ibhokisi legatsha lekhebula lokuxhuma kuvame ukuthandwa ukuze kuthuthukiswe ukuphepha nokuthembeka, njengoba kugwema amalunga amaningi asemgqeni angcwatshwe.

Izinhlobo Eziyinhloko Nokucushwa 

Amabhokisi egatsha lekhebula ngokuvamile zihlukaniswa ngezigaba ngokusekelwe ezingxenyeni zazo zangaphakathi kanye nefilosofi yokuklama.

Amabhokisi Okuhlangana Ayisisekelo:Lezi yizinhlobo ezilula kakhulu, ezingenazo imishini yokushintsha. Zigcina nje izindawo zokuqeda ikhebula kanye nezesekeli zokuxhuma. Izintambo ezingenayo neziphumayo zixhunywe ngogesi ngamandla afanayo. Zifanelekela ukuhlukaniswa noma ukuhlanganiswa okuqondile.

Amabhokisi Athuthukisiwe Anezinkinobho:Lawa mabhokisi awabandakanyi nje kuphela izindawo zokuxhuma kodwa futhi neyunithi eyodwa noma ngaphezulu ye-switchgear, njenge-SF6-insulated load-break switches. Lokhu kuvumela ukulawula isekethe, ukuhlukaniswa, kanye nokushintsha ukucushwa kwenethiwekhi. Angasebenza ngendlela efanayo namayunithi amakhulu endandatho yangaphandle (ama-RMU), enikeza ukuguquguquka okukhulu kokusebenza.

Isitayela saseMelika vs. Isitayela saseYurophu:Lona umehluko obalulekile osekelwe kubuchwepheshe bokuxhumana kwangaphakathi.

Isitayela saseMelika:Iziciukuhlanganisa okulinganayouhlelo olusebenzisa ibha yebhasi evalekile enezixhumi ze-plug-in. Izici ezibalulekile zifaka phakathi umnyango wangaphambili owodwa, ububanzi obuncane, kanye nekhono lezixhumi zegatsha ze-200A zokuxhumeka noma ukukhishwa ngaphansi komthwalo, okusebenza njengeswishi.

Isitayela saseYurophu:Ngokuvamile isebenzisaukuhlanganisa uchungechungeIndlela lapho izixhumi ezimise okwe-T zixhunywa khona ngeketanga. Ngokuvamile zineminyango ezinhlangothini zombili, zisebenzisa ama-bushings odongeni njenge-busbar, futhi zisebenzisa izixhumi ezinamabhawodi ezinesilinganiso esijwayelekile esingu-630A. Lo mklamo unikeza ukuhlelwa kwekhebula okucacile.

Izici Eziyinhloko Nezinzuzo 

Ifakwe Ukushisa Okugcwele Futhi Ivaliwe:Ihlinzeka ngezinga eliphezulu lokuphepha kubasebenzi futhi ivikelwe ezicini zemvelo ezifana nothuli, umswakama kanye nezikhukhula.

Incane futhi iyaguquguquka:Ukwakheka kwe-modular kuvumela ukucushwa okuhlukahlukene ukuhlangabezana nezidingo ezahlukene zocingo, okwenza kube kuhle ezindaweni zasemadolobheni ezincishisiwe.

Ukugcinwa Okuphansi:Yakhelwe ukusebenza ngaphandle isikhathi eside, okuthembekile futhi inakekelwa kancane.

Ukuphepha Okuthuthukisiwe:Amamodeli anamaswishi afaka phakathi ama-interlock okuphepha (“ama-interlock amahlanu”) kanye nezici ezifana nezinkomba zamaphutha ekhebula ukuthola izinkinga ngokushesha.

Izicelo Ezivamile 

Amabhokisi egatsha lekhebula asetshenziswa kabanzi ku:

Ukuthuthukiswa kwenethiwekhi yasemadolobheni kanye nezinhlelo zokusabalalisa ezisekelwe kukhebula.

Amapaki ezimboni, imiphakathi yokuhlala, kanye nezikhungo zezentengiselwano.

Izakhiwo ezinkulu ezifana nezimayini, amasimu kawoyela, kanye nezindawo zokukhiqiza.

Noma yiluphi uhlelo lokusebenza oludinga ukuhlanganiswa kwekhebula okuthembekile nokuguquguqukayo.
