General hais txog IEC:
Lub International Electrotechnical Commission (IEC) yog lub koom haum thoob ntiaj teb cov qauv uas npaj thiab tshaj tawm cov qauv thoob ntiaj teb rau txhua yam khoom siv hluav taws xob, hluav taws xob, thiab lwm yam thev naus laus zis - suav nrog hu ua "electrotechnology". IEC cov txheej txheem npog ntau yam thev naus laus zis los ntawm kev tsim hluav taws xob, kev sib kis, thiab kev xa mus rau cov khoom siv hauv tsev thiab cov khoom siv hauv chaw ua haujlwm, semiconductors, fiber ntau optics, roj teeb, hnub ci zog,
nanotechnology, thiab marine zog thiab lwm yam. Lub IEC kuj tseem tswj hwm plaub] thoob ntiaj teb kev ntsuas kev sib raug zoo uas tau lees paub tias cov khoom siv, cov tshuab, lossis cov khoom ua tau raws li nws cov qauv thoob ntiaj teb Switchgear IEC cov qauv:
IEC Standards ua lub luag haujlwm tseem ceeb hauv kev paub thiab ntsuas cov khoom siv sib txawv. Cov qauv yog ib qho tseem ceeb rau kev nkag siab, kev sim, thiab kev qhia ntau yam ntawm switchgear.
Hais txog IEC 62271-100:
Cov qauv no yog ib feem 100 ntawm IEC 62271 luam tawm txog switchgear. Cov qauv no feem ntau yog siv rau nruab nrab-voltage thiab high-voltage Circuit Court breakers. Qhov no ntawm IEC 62271 qhia txog cov hluav taws xob hluav taws xob tsim rau sab hauv tsev lossis sab nraum zoov thiab kev ua haujlwm ntawm zaus ntawm 50 Hz thiab 60 Hz ntawm cov tshuab uas muaj qhov hluav taws xob siab tshaj 1000 V., Nws tsuas yog siv tau rau peb-ncej Circuit Court breakers siv peb theem systems thiab ib-ncej Circuit Court breakers rau siv nyob rau hauv ib-theem systems. Nco tseg: Txawm hais tias feem ntau mob siab rau peb-theem systems, tus qauv no kuj tuaj yeem siv rau ib-theem lossis ob theem systems.
IEC62271-100 tsuas yog siv tau rau peb-ncej circuit-breakers rau siv nyob rau hauv peb-theem systems thiab ib-ncej Circuit Court breakers rau siv nyob rau hauv ib-theem systems. Ob-ncej Circuit Court-breakers rau siv nyob rau hauv ib-theem systems thiab kev siv ntawm zaus qis dua 50 Hz yog nyob rau hauv kev pom zoo ntawm cov chaw tsim tshuaj paus thiab cov neeg siv.
Cov qauv no kuj tseem siv tau rau cov khoom siv ua haujlwm ntawm Circuit Court breakers thiab rau lawv cov cuab yeej pabcuam. Txawm li cas los xij, lub Circuit Court-breaker nrog lub kaw lus rau kev ua haujlwm ntawm kev ua haujlwm tsis raug them los ntawm tus qauv no, vim tias qhov ntsuas luv luv-circuit ua-tam sim no tsis tuaj yeem raug teev tseg, thiab cov kev ua haujlwm ntawm phau ntawv no tuaj yeem tsis pom zoo vim kev xav txog kev nyab xeeb.
Cov kev cai rau high voltage Circuit Court-breakers nrog rau kev txhob txwm tsis-simultaneity ntawm tus ncej yog nyob rau hauv kev txiav txim siab; circuit-breakers muab ib-ncej auto-reclosing yog nyob rau hauv lub Scope ntawm tus qauv no.
