Cov qauv hauv tsev thiab thoob ntiaj teb rau Tsawg-voltage Switchgear
Jul 13, 2023
Cov qauv hauv tsev thiab thoob ntiaj teb rau cov khoom siv hluav taws xob tsawg
ANSI yog siv los xa mus rau North American cov qauv feem ntau, thaum IEC yog siv rau cov qauv thoob ntiaj teb hauv cheeb tsam uas tsis yog North America, tshwj tsis yog cov qauv tshwj xeeb tau hais txog. UL, NEMA, thiab ANSI cov qauv qhia kom meej qhov sib txawv ntawm cov khoom sib txawv ntawm cov khoom siv hluav taws xob tsawg thiab cov khoom siv tswj tau tsim los rau kev lag luam sib txawv. Hlau enclosed switchgear, low-voltage txee, faib txee, Bus duct thiab lub cev muaj zog tswj txee txais cov qauv sib txawv. Cov no yog tsim los ntawm cov qauv sib txawv ntawm lub cev. Qee cov khoom muaj ntau tus qauv, txhua tus tsim los ntawm ib lub cev sib txawv, suav nrog ntau yam ntawm kev tsim thiab kev siv, thiab qee zaum muaj cov cai sib txawv rau tib yam ntxwv. Tus qauv IEC tsuas yog npog tag nrho cov khoom siv hluav taws xob tsawg no hauv ib tus qauv thiab muab lawv tag nrho rau hauv ib qho khoom.
Qhov sib txawv tshaj plaws ntawm ANSI thiab IEC cov qauv yog tias tus qauv ANSI yog tsim rau ib qho, tshwj xeeb hauv hluav taws xob, nrog rau kev faib thoob ntiaj teb thiab hauv av (grounding) architecture. Lawv kuj tau tsim los rau cov lej hluav taws xob. Ntawm qhov tod tes, IEC cov qauv yuav tsum them rau ntau yam ntawm cov tshuab hluav taws xob thiab yuav tsum muaj feem xyuam rau ntau qhov sib txawv ntawm cov hluav taws xob.
Tus qauv ANSI muab cov txheej txheem ntxaws ntxaws dua li IEC, yog li tso cai rau ntau txoj kev daws teeb meem. Tus qauv ANSI tseem muab cov ntaub ntawv ntawm cov khoom siv nrog cov khoom siv, nrog rau IEC npog cov khoom siv no hauv cov qauv sib cais thiab ywj pheej.
UL (Underwriters Laboratories) thiab CSA (CSA Group) saib xyuas kev ua raws li ANSI cov qauv. Feem ntau, lawv siv cov qauv qis-voltage hauv qab no thiab ntxiv qee qhov kev xav tau:
ANSI / IEEEEC37.20.1, UL1558 thiab ANSI C37.51 yog siv rau cov hlau kaw uas tsis tshua muaj hluav taws xob hluav taws xob Circuit Court breaker switchgear;
ANSI / UL845 thiab NEMA ICS1 thiab ICS3 yog tsim rau cov khoom siv hluav taws xob qis qis;
ANSI/IEEEEC37.21 yog siv los tswj cov khoom faib khoom;
ANSI/UL891 thiab NEMAPB2 thiab PB2.1 yog siv rau cov thawv xa khoom;
ANSI / UL67 thiab ANSI / NEMA PB1 yog siv los ua cov qauv kev nyab xeeb rau cov keyboards.
UL857 thiab NEMA BU1 yog siv rau Bus duct.
Feem ntau, kev ua raws li IEC cov qauv tsis raug saib xyuas. Cov neeg tsim khoom thiab cov neeg siv khoom yog lub luag haujlwm los ua kom muaj kev ua raws li cov qauv siv rau hauv zos. Nws yog qhov ib txwm muaj rau qhov chaw sim ua qhov ntsuas luv luv thiab arc txwv kev sim, zoo li yog tias lwm qhov kev sim ua tsis tiav, cov kev sim no yuav ua pov thawj txoj kab kawg ntawm kev tiv thaiv. Tus qauv IEC tsuas muaj ib qho IEC 60439-1, tab sis nws muaj ntau yam qauv derivative.
Txhawm rau muag cov khoom siv hluav taws xob tsawg hauv European Union (EU), nws yuav tsum ua raws li cov cai ntawm European tus qauv EN60439-1 thiab dais CE cim. Qhov no yog IEC, thiab kom cov cuab yeej siv tau zoo hauv EU, yuav tsum muaj qhov sib txawv. Tam sim no, ob qho qauv no yeej zoo ib yam, tab sis tsis muaj kev cai lij choj kom ua li ntawd. EU lub teb chaws feem ntau muaj cov qauv sib npaug hauv tebchaws rau EN, xws li BSEN60439-1 (UK) lossis CEI17-13/1 (Ltalis), uas yog EN cov qauv nrog cov ntawv txuas hauv tebchaws. Cov kab lus ntxiv no ua rau EN cov cuab yeej siv nyab xeeb hauv cov tebchaws / cheeb tsam no. EU txoj cai txwv tsis pub nws siv raws li kev txwv kev lag luam, yog li cov kev sib txawv no yuav tsum raug txo kom tsawg li ntau tau. Cov neeg tsim khoom yuav tsum ua kom pom kev ua raws li cov qauv. Muaj cov ntsiab lus nruj thiab txwv txoj hauv kev los tawm tsam xws li kev lees paub.
Yuav kom muag cov khoom siv hluav taws xob tsawg hauv Suav teb raug cai, lawv yuav tsum ua raws li cov kev cai ntawm peb lub teb chaws tus qauv GB/T7251-1 thiab dais daim ntawv pov thawj CCC. Qhov no yog rau kev nyab xeeb ntawm cov khoom siv uas txawv ntawm IEC cov qauv.
Lwm lub tebchaws, xws li Australia thiab Brazil, kuj muaj lawv tus kheej IEC tus qauv derivatives (AS 3439 thiab NBR 6808), tab sis kev ua raws li cov qauv no feem ntau yog ib qho kev cog lus es tsis yog kev cai lij choj, thiab zoo li EN cov qauv, kev hloov pauv feem ntau yog tsawg.
