Izinzuzo Eziyinhloko Ze-ANSI Bushings

I. Izinhlobo Eziyinhloko Nezimo Zokusetshenziswa
Ama-bushing e-ANSI angahlukaniswa ngezinhlobo ezintathu ngokusekelwe emisebenzini nasezinhlelweni zawo, afanelana kahle nezidingo ezijwayelekile zegridi yamandla yaseNyakatho Melika:
1. I-ANSI post-type ceramic bushing (I-ANSI Post-Type Ceramic Bushing)
 Ukusetshenziswa: Ukusekelwa kwebhasi lesiteshi esincane, ukufakelwa komugqa ophumayo we-transformer, ukuhlukaniswa kwebhasi lebhasi eline-voltage ephezulu kumakhabethe okusabalalisa;
 Izici: Kufakwe ngokuma, ngama-flange ajwayelekile e-ANSI phezulu (njenge-flanges enezimbobo ezine/izimbobo eziyisithupha, enezikhala zemigobo ngokuhambisana ne-ANSI B16.5), kanye nama-terminal okuxhuma phansi ahambisana nama-busbar avamile angunxande noma izixhumi zekhebula eNyakatho Melika;
 Izimo ezijwayelekile: ama-transformer angu-10kV/35kV kumagridi kagesi asemadolobheni aseNyakatho Melika, ukwesekwa kwebhasi le-GIS yangaphandle (i-Gas Insulated Switchgear).
2. I-ANSI Wall-Penetration Ceramic Bushing efaka udonga (i-ANSI Wall-Penetration Ceramic Bushing)
 Ukusetshenziswa: Imigqa enamandla kagesi aphezulu edlula ezindongeni zesakhiwo, amakhabethe ensimbi (njengamakamelo okusabalalisa, izingxenye ze-workshop zasefektri);
 Izici: Ingxenye ephakathi iyisigaba esingena odongeni (ubude obuhlelwe ngokwezifiso ngokobukhulu bodonga, ngokuvumelana nokubekezelela ubude be-ANSI C37.34), zombili iziphetho zinezibani ezingangeni manzi ukuvimbela ukungena komhwamuko wamanzi ezinhlangothini zombili zodonga;
 Izimo ezijwayelekile: Izintambo zikagesi eziphezulu ezingu-138kV ezidlula ezindongeni ezakhiweni zezimboni, ama-bushing emigqa engenayo angu-10kV ezakhiweni zezentengiselwano.
3. I-ANSI transformer ceramic bushing (i-ANSI Transformer Ceramic Bushing)
 Ukusetshenziswa: Ukuxhumeka kwezintambo ezigoqayo zama-transformer acwiliswe ku-oyili kanye nama-transformer ohlobo olomile kugridi yamandla yangaphandle;
 Izici: Isakhiwo sokulinganisa amandla kagesi esakhelwe ngaphakathi ngokwezindinganiso ze-ANSI (ukunciphisa ukugcwala kwensimu kagesi yangaphakathi), amatheminali okuxhuma anama-valve okusiza ukucindezeleka (akhulula ngokuzenzakalelayo ingcindezi uma kwenzeka amaphutha), ahambisana nokwakheka "kokuphuma phezulu" noma "kokuphuma eceleni" okusetshenziswa kakhulu kuma-transformer aseNyakatho Melika;
 Izimo ezijwayelekile: ama-transformer e-voltage aphezulu kakhulu angu-500kV kugridi yamandla yaseNyakatho Melika, ama-transformer e-box-type angu-35kV emapulazini omoya.
II. Izinzuzo Eziyinhloko Zezinsika Ze-ANSI
1. Ukushintshana okujwayelekile: Ubukhulu kanye nezixhumi kuhambisana ngokugcwele nezindinganiso ze-ANSI, okuvumela ukushintshwa okuqondile kwe-bushings efanayo emishinini ekhona emakethe yaseNyakatho Melika, kunciphisa izindleko zokuvuselela;
2. Ukuthembeka okuqinile: Ngokusebenzisa “ukuhlolwa kohlobo oluphelele” ngokwezidingo ze-ANSI (njengokuhlolwa kokudlidliza komshini okungu-1000, ukuhlolwa kokujikeleza kokushisa), isikhathi sokuphila singafinyelela eminyakeni engaphezu kwengu-30, sihlangabezane nezidingo “zokugcinwa okuphansi” zegridi yamandla yaseNyakatho Melika;
3. Ukuzivumelanisa nezimo eziningi: Kuhlanganisa wonke amazinga kagesi kusukela ekusabalalisweni kwamandla kagesi aphansi kuya ekudlulisweni kwamandla kagesi aphezulu kakhulu, kucatshangelwa izindawo ezivamile zaseNyakatho Melika njengokungcola okukhulu ngaphandle, amazinga okushisa aphezulu angaphakathi, kanye nenkungu kasawoti ogwini;
4. Isiqinisekiso sokuthobela imithetho: Sihambisana nesitifiketi se-North American UL (Underwriters Laboratories), isitifiketi se-CSA (Canadian Standards Association), esivumela ukungena ngqo emakethe yaseNyakatho Melika ukuze kuthengiswe.
III. Isifinyezo
Ama-bushing e-ANSI awumphumela wokuhlanganiswa okujulile “kwezinzuzo zezinto ze-ceramic” kanye “nohlelo olujwayelekile lwaseNyakatho Melika”. Awagcini nje ngokuba nezici zokuvikela, ukumelana nesimo sezulu, kanye nokumelana nokugqwala kwama-bushing e-ceramic, kodwa futhi ngomklamo ojwayelekile wezindinganiso ze-ANSI, axazulula amaphuzu “okuhambisana” kanye “nokuthembeka” kwamaphrojekthi awela imingcele. Ayisisombululo esithandwayo sezingxenye zokuvikela ezinamandla aphezulu kugridi yamandla yaseNyakatho Melika kanye namaphrojekthi aphesheya kwezilwandle amabhizinisi aseNyakatho Melika. Kungakhathaliseki ukuthi yiziteshi ezintsha noma ukuvuselelwa kwamagridi kagesi amadala, ama-bushing e-ANSI ceramic angaqinisekisa ukusebenza okuzinzile kwesikhathi eside kohlelo lwamandla ngokusebenza okujwayelekile.
