Cov Zoo Tseem Ceeb ntawm ANSI Bushings

I. Cov Hom Tseem Ceeb thiab Cov Xwm Txheej Thov
ANSI bushings tuaj yeem muab faib ua peb hom raws li lawv cov haujlwm thiab cov qauv, phim cov kev xav tau ntawm North American power grid:
1. ANSI hom ceramic bushing (ANSI Hom Ceramic Bushing)
 Daim Ntawv Thov: Kev txhawb nqa lub busbar substation, kev rwb thaiv kab tawm ntawm lub transformer, kev rho tawm lub busbar hluav taws xob siab hauv cov txee faib khoom;
 Cov yam ntxwv: Nruab ntsug, nrog ANSI tus qauv flanges rau sab saum toj (xws li 4-qhov/6-qhov flanges, nrog qhov sib nrug raws li ANSI B16.5), thiab cov chaw txuas ntawm qab sib xws nrog cov busbars rectangular lossis cable connectors hauv North America;
 Cov xwm txheej ib txwm muaj: 10kV/35kV transformers hauv cov nroog fais fab hauv North America, sab nraum zoov GIS (Gas Insulated Switchgear) kev txhawb nqa busbar.
2. ANSI phab ntsa-nkag mus rau hauv cov khoom siv ceramic bushing (ANSI Wall-Penetration Ceramic Bushing)
 Daim Ntawv Thov: Cov kab hluav taws xob siab hla dhau phab ntsa tsev, cov txee hlau (xws li chav faib khoom, cov chaw faib khoom hauv Hoobkas);
 Cov yam ntxwv: Nruab nrab yog qhov nkag mus rau hauv phab ntsa (qhov ntev raws li qhov tuab ntawm phab ntsa, raws li ANSI C37.34 qhov ntev kam rau siab), ob qho kawg nrog cov flanges dej kom tiv thaiv cov pa dej nkag mus rau ob sab ntawm phab ntsa;
 Cov xwm txheej ib txwm muaj: 138kV cov xov hluav taws xob siab hla dhau phab ntsa hauv cov tsev lag luam, 10kV cov kab nkag hauv cov tsev lag luam.
3. ANSI transformer ceramic bushing (ANSI Transformer Ceramic Bushing)
 Daim Ntawv Thov: Kev sib txuas ntawm cov xov hlau ntawm cov roj-immersed transformers thiab cov hom qhuav-hom transformers rau lub zog sab nraud grid;
 Cov yam ntxwv: Cov qauv sib npaug ntawm lub zog hluav taws xob uas ua tau raws li ANSI cov qauv (txo qhov kev sib sau ua ke ntawm lub zog hluav taws xob sab hauv), cov qhov txuas nrog cov qhov tso pa tawm siab (tsis siv neeg tso pa tawm thaum muaj qhov yuam kev), sib xws nrog "sab saum toj" lossis "sab tawm" uas feem ntau siv hauv North American transformers;
 Cov xwm txheej ib txwm muaj: 500kV ultra-high voltage transformers hauv North American power grid, 35kV box-type transformers hauv cov chaw ua liaj ua teb cua.
II. Cov txiaj ntsig tseem ceeb ntawm ANSI Bushings
1. Kev sib pauv tau raws li tus qauv: Qhov loj me thiab cov interfaces ua raws li ANSI cov qauv, tso cai hloov pauv ncaj qha ntawm cov bushings specification tib yam hauv cov khoom siv uas twb muaj lawm hauv North American kev ua lag luam, txo cov nqi kho dua tshiab;
2. Kev ntseeg siab ruaj khov: Los ntawm "kev xeem hom puv ntoob" raws li ANSI cov kev cai (xws li 1000 qhov kev sim kev co, kev sim cua sov), lub neej ua haujlwm tuaj yeem ncav cuag ntau dua 30 xyoo, ua tau raws li "kev saib xyuas qis" ntawm North American power grid;
3. Kev hloov pauv tau ntau qhov xwm txheej: Npog txhua qib voltage los ntawm kev faib hluav taws xob qis mus rau kev xa hluav taws xob siab heev, xav txog cov chaw ib puag ncig hauv North America xws li muaj kuab paug ntau sab nraum zoov, kub hauv tsev siab, thiab pos huab ntsev ntug dej hiav txwv;
4. Kev lees paub ua raws li txoj cai: Ua raws li daim ntawv pov thawj North American UL (Underwriters Laboratories), daim ntawv pov thawj CSA (Canadian Standards Association), ua rau nkag mus rau hauv kev lag luam North American ncaj qha rau kev muag khoom.
III. Kev Txheeb Xyuas
ANSI bushings yog qhov tshwm sim ntawm kev sib koom ua ke ntawm "cov khoom siv ceramic zoo" thiab "North American standard system". Lawv tsis tsuas yog muaj cov yam ntxwv ntawm kev rwb thaiv tsev, kev tiv thaiv huab cua, thiab kev tiv thaiv corrosion ntawm cov ceramic bushings, tab sis kuj los ntawm kev tsim qauv ntawm ANSI cov qauv, daws cov teeb meem "kev sib raug zoo" thiab "kev ntseeg siab" ntawm cov haujlwm hla ciam teb. Lawv yog cov kev daws teeb meem zoo tshaj plaws rau cov khoom siv rwb thaiv tsev siab hauv North American power grid thiab cov haujlwm txawv teb chaws ntawm North American cov tuam txhab. Txawm hais tias nws yog cov chaw hloov pauv tshiab lossis kev kho dua tshiab ntawm cov hluav taws xob qub, ANSI ceramic bushings tuaj yeem ua kom lub zog ua haujlwm ruaj khov ntev nrog kev ua tau zoo.
