Nrov cov hloov chaw thiab nws cov yam ntxwv thiab cov qauv kev lag luam thoob ntiaj teb

Cov lus qhia luv luv hloov pauv hloov

Switchgear ua lub luag haujlwm tseem ceeb hauv lub zog niaj hnub rau lub zog hluav taws xob, kis tau, xa tawm, thiab kev faib khoom. Nws lub ntsiab ua haujlwm suav nrog:

Kev tiv thaiv cov khoom siv hluav taws xob thiab khoom siv: Switchgear siv cov khoom siv hluav taws xob zoo li cov hluav taws xob sib xyaws kom rov ua kom nrawm nrawm, ntau dua, lossis lwm yam kev puas tsuaj ntxiv.

Tswj Ua Haujlwm: Nws tso cai rau phau ntawv lossis tsis siv neeg hloov pauv ntawm cov hluav taws xob, ua kom muaj zog siv hluav taws xob yooj ywm thiab tswj kev ua haujlwm.

Muab cais nyob ib leeg: Lub sijhawm tu lossis kho, hloov pauv tuaj yeem cais cov feem tshwj xeeb ntawm cov kab ke, kom muaj kev nyab xeeb.

Switchgear yog feem ntau categorized rau hauvHigh-voltage switchear(rau volfages siab tshaj 3.6 kV) thiabTsawg-voltage switchgear(rau voltages hauv qab no 1 kV), nyob ntawm nws cov kev ua haujlwm voltage ntau. Nws yog dav siv nyob rau hauv kev lag luam xws li cov nqi hluav taws xob, metallurgy, tshuaj tsuag cov nroj tsuag, thiab vaj tse.

Cov Qauv Thoob Ntiaj Teb rau Switchgear

Switchgear Design, kev tsim khoom, kev sim, thiab kev ua haujlwm yog tswj hwm los ntawm ntau tus qauv nruj thoob ntiaj teb. Hauv qab no yog qee qhov ntawm tus qauv tseem ceeb:

Cov Qauv Txheej Txheem Thoob Ntiaj Teb (IEC)

IEC 62271 Series: High-voltage switchgear thiab Contregear

Iec {62271-200: AC hlau-hlau hloov thiab tswj hwm

Iec {62271-100: High-voltage alcating tam sim no Circuit Court

Iec {62271-102: AC Disconnectors thiab eque hloov

Iec {62271-1: Cov kev xav tau rau high-voltage switchgear thiab tswj hwm

IEC 61439 Series: Tsawg-voltage switchgear thiab Contregear

Iec {61439-1: Cov kev cai dav dav rau cov hluav taws xob tsawg-voltage switchgear sib dhos

Iec {61439-2: Faiv fab hloov mus thiab tswj kev sib sau ua ke

Iec {61439-3: Faib cov laug cam

Cov Qauv European (En Cov Qauv)

European cov teb chaws feem ntau tau txais IEC cov qauv, xws liEn 62271-200, uas ua kom haum nrog iec 62271-200} rau high-voltage switchgear chaw sib dhos.

American Cov Qauv (Ansi / Ieee / NEMA)

Hauv Tebchaws Meskas, Switchear yog feem ntau teev los ntawm cov qauv hauv qab no:

Ansi / IEEE C37 Series:

Ansi / IEEE C37.20.1: Hlau-Nrog Cov Hluav Taws Xob Tsawg-Voltage Switchgear

Ansi / IEEE C37.20.2: Hlau-Clad High-Voltage Switchgear

Ansi / IEEE C37.20.7: Arc-resistant switchgear kuaj

NEMA Cov Qauv:

Nema sg -5: Faiv fab hloov tes

Cov Qauv Suav (GB tus qauv)

Hauv Suav teb, cov qauv hloov pauv yog cov txheej txheem iC tab sis suav nrog kev hloov kho lub teb chaws tshwj xeeb:

GB / T 3906:) {{{{6-40. 5 kV AC hlau-ua ke Swaygear thiab Contregear

GB / T 11022: Kev Xav Tau Kev Xav Rau High-Volfage Switchgear thiab Contregear

GB / T 7251 Series: Tsawg-voltage switchgear thiab tswj kev sibtham

Lub ntsiab

Switchgear yog qhov tseem ceeb ntawm cov tshuab hluav taws xob hluav taws xob, thiab nws cov qauv tau tsim qauv thoob ntiaj teb. TusIC tus qauvyog qhov feem ntau dav siv thiab ua lub hauv paus rau ntau tus qauv hauv tebchaws thiab cheeb tsam (piv txwv li, ensi / ieee hauv Asmeskas, thiab GB hauv Suav teb). Cov qauv no kom ntseeg tau tias kev nyab xeeb, kev ntseeg tau, thiab kev sib tshuam ntawm lub tshuab hloov ntawm cov tshuab nqus av thoob ntiaj teb.
