Dab tsi yog IEC Standard for Impulse Test?
Sep 18, 2026
Nug seb tus txheej txheem twg tswj hwm qhov kev sim siab thiab cov lus teb luv yog IEC 60060-1 - tab sis qhov ntawd tsuas yog lub qhov rooj. Ib tsev neeg me ntawm cov ntaub ntawv zaum tom qab nws, thiab txhua tus teb cov lus nug sib txawv: dab tsi waveform, ntsuas li cas, nyob rau hauv qhov chaw twg.
IEC 60060-1: Qhov twg lub waveform nyob
IEC 60060-1 yog tus qauv hauv paus, thiab nws yog qhov uas koj hais thaum ib tus neeg nug tias xob laim yog dab tsi. 2025 tsab (Edition 4.0, luam tawm Lub Plaub Hlis 2025) yog lub npe "Cov ntsiab lus dav dav thiab cov kev xeem xeem" - hloov pauv los ntawm 2010 Edition 3.0, uas yog lub npe "Cov ntsiab lus dav dav thiab cov kev xav tau xeem." Nws siv thoob plaws dielectric xeem nrog alternating voltage, ncaj qha voltage, thiab impulse voltage, thiab nws txhais cov qauv duab ua ke nrog lawv tolerances:
| Waveform | Pem hauv ntej lub sij hawm (T1) | Lub sijhawm ntev (T2) |
|---|---|---|
| xob laim impulse (LI) | 1.2 µs ±30% (0.84–1.56 µs) | 50 µs ±20% (40–60 µs) |
| Hloov impulse (SI) | 250 µs ±20% (200–300 µs) | 2500 µs ±60% (1000–4000 µs) |
Cov qhov rais no yog tag nrho cov ntsiab lus. Lub tshuab hluav taws xob tuaj yeem tua hluav taws thiab ua kom pom qhov zoo tshaj plaws uas tseem ua tsis tau raws li tus Tsov tus tw drifted sab nraum ± 20%. Kev ntsuas qhov ntsuas waveform kom raug yog qhov sib txawv ntawm qhov kev sim siv tau thiab rov ua dua.
IEC 60060-2 thiab IEC 61083: Ua pov thawj qhov ntsuas
Tsim ib qho kev txhawb zog yog ib nrab ntawm txoj haujlwm - ib nrab yog ua pov thawj tias koj ntsuas qhov tseeb. IEC 60060-2 suav nrog kev ntsuas ntsuas: kev faib tawm, kauj ruam teb, thiab raug. Tsab ntawv 2025 (Ib tsab 3) txuas ntxiv siv tau rau kev ntsuas cov tshuab siv nyob rau hauv txhua qib txheej txheem rwb thaiv tsev teev tseg hauv IEC 60071-1. Rau cov digitizers thiab cov software uas ntsuas cov kab sau tseg, IEC 61083-1 thiab IEC 61083-2 teeb tsa cov cai.
IEC 60060-3 thiab IEC 62475: Kev ua haujlwm ntawm qhov chaw thiab impulse tam sim no
Ob cov ntaub ntawv tawm ntawm txoj kab tseem ceeb. IEC 60060-3: 2006 txhais cov ntsiab lus thiab cov tseev kom muaj rau kev sim ntawm qhov chaw, qhov chaw hauv av, txwv qhov chaw, thiab hluav taws xob cuam tshuam ua kom huv hauv chav kuaj tsis tuaj yeem ua tsis tau. Impulse currents yog ib zaj dab neeg sib cais tag nrho: exponential tam sim no impulses ntawm 1/20 µs, 4/10 µs, thiab 8/20 µs, ntxiv rau 10/350 µs xob laim tam sim no impulses, tam sim no tswj hwm los ntawm IEC 62475 es tsis yog 60060 series.
IEC vs IEEE: tib qhov kev xeem, sib txawv lej
North American tej yaam num feem ntau hais txog IEEE Std 4 hloov. Ob leeg yog broad harmonized tab sis tsis interchangeable. Lub sij hawm pem hauv ntej yog qhov piv txwv meej tshaj plaws: IEC 60060-1 muab tau nws li 1.67 npaug ntawm 30%-rau-90% ntu, thaum IEEE Std 4 ntsuas lub sijhawm nce 10%-rau-90% ncaj qha. Daim ntawv tshaj tawm kev ntsuas ntsuas rau ib tus qauv tsis tuaj yeem ua raws li lwm tus, uas yog qhov tseem ceeb thaum lub tshuab hloov hluav taws xob ua rau IEEE cov cai yuav raug xa mus rau qhov kev qhia tshwj xeeb rau IEC.
Siv nws rau cov khoom siv tiag tiag
Cov qauv hauv paus txhais qhov kev xeem; cov qauv khoom txhais cov nqi. Cable impulse testing ua raws li IEC 60230. Rau transformers, lub chopped xob laim impulse - ib tug tag nrho nthwv dej txhob txwm truncated los ntawm ib tug chopping sib txawv, feem ntau nyob rau hauv 2 mus rau 6 µs - yog ib tug yuav tsum tau hom kev xeem, nrog rau qhov ntsuas voltage thiab lub sij hawm rau chopping tabulated nyob rau hauv IEEE C507.15.12. Yog tias koj tab tom qhia txog qhov kev sim lossis yuav lub tshuab hluav taws xob impulse, paub meej tias tus qauv twg lees txais cov qauv siv ua ntej cov cuab yeej raug txiav txim, tsis yog tom qab thawj waveform ua tsis tiav.
