3. Lub tshuab hluav taws xob tau teeb tsa ua peb-seem, uas muaj cov yam ntxwv ntawm cov qauv compact thiab me me, lub kaw lus tiv tauj tau kaw rau hauv lub phaj insulating, thiab txhua theem ntawm kev sib cuag kuj tau sib cais los ntawm lub phaj insulating los ua lub chamber me me, thiab lub tshuab tswj hwm ntse, lub tshuab ua haujlwm phau ntawv, thiab lub tshuab ua haujlwm hluav taws xob tau teeb tsa ua ntej nws tig los tsim lawv tus kheej cov chav nyob ywj pheej. Yog tias ib qho ntawm cov chav tsev tawg, nws tuaj yeem raug tshem tawm thiab hloov nrog ib qho tshiab.
4. Lub tub rau khoom siv hluav taws xob yog tsim los ntawm lub tshuab hluav taws xob ntsaws thiab lub hauv paus tub rau khoom. Lub tsheb ciav hlau hauv lub hauv paus tub rau khoom tuaj yeem rub tawm thiab rub tawm, thiab lub tshuab hluav taws xob ntsaws rau ntawm lub tsheb ciav hlau kom tawm ntawm lub tub rau khoom, thiab lub voj voog tseem ceeb txuas nrog los ntawm kev sib txuas ntawm lub busbar ntsaws rau hauv lub tshuab hluav taws xob ntsaws thiab lub choj sib cuag ntawm lub hauv paus tub rau khoom.
5. Lub tub rau khoom hom Circuit Court breaker muaj peb txoj haujlwm ua haujlwm: qhov chaw "kev sib txuas", qhov chaw "sim", thiab qhov chaw "kev sib cais". Kev hloov txoj haujlwm yog ua tiav los ntawm kev ntsia hlau rau hauv lossis tawm ntawm tus kov. Qhov qhia txog peb txoj haujlwm yog tso tawm los ntawm tus pointer ntawm lub nqaj ntawm lub hauv paus qis ntawm lub tub rau khoom.
6. Thaum nyob rau hauv txoj hauj lwm "kev sib txuas", ob lub voj voog tseem ceeb thiab lub voj voog thib ob raug qhib; thaum nyob rau hauv txoj hauj lwm "kev sim", lub voj voog tseem ceeb raug txiav tawm thiab sib cais los ntawm cov khoom siv rwb thaiv tsev. Tsuas yog lub voj voog thib ob raug qhib, thiab qee qhov kev sim ua haujlwm tsim nyog tuaj yeem ua tau, thaum nyob rau hauv txoj hauj lwm "kev sib cais", lub voj voog tseem ceeb thiab lub voj voog thib ob raug txiav tawm tag nrho. Ntxiv mus, lub tub rau khoom hom circuit breaker muaj lub cuab yeej sib txuas lus. Lub circuit breaker tsuas yog kaw tau ntawm txoj hauj lwm txuas lossis txoj hauj lwm sim. thiab lub circuit breaker tsis tuaj yeem kaw ntawm txoj hauj lwm nruab nrab ntawm kev sib txuas thiab kev sim.
Lub tshuab sib txuas ntawm lub tshuab hluav taws xob (siv tau rau hom tub rau khoom thiab hom ruaj khov) tau qhia hauv Daim Duab 6. Tus neeg siv tuaj yeem siv lub tshuab sib txuas cais los hloov ob lossis peb chav.

Yog tias ob lub circuit breakers sib txuas ua ke tsuas yog yuav tsum tshem tawm lub circuit breaker sab saum toj.
Kev sib txuas mos mos (Muaj rau kab rov tav thiab ntsug, tsim nyog rau ntawm cov txee sib ze lossis hauv tib lub txee)
Txoj kev tiv thaiv kev ua txhaum av
Tus maub los tswj tau muab faib ua ob txoj kev tiv thaiv sib txawv, ib qho yog hom sib txawv (T), thiab tus maub los tswj tiv thaiv raws li qhov sib sau ua ke ntawm peb-theem tam sim no thiab lub vector tam sim no ntawm kab nruab nrab. Raws li tus lej ntawm cov ncej ntawm lub tshuab hluav taws xob, nws tau muab faib ua peb daim ntawv: 3PT, 4PT., thiab (3P + N) T, uas tau qhia hauv daim duab hauv qab no (a. b, thiab c). Lwm txoj kev yog hom tam sim no hauv av (W). Tus maub los tswj ncaj qha coj cov teeb liab tam sim no ntawm lub transformer tam sim no ntxiv ntawm qhov nruab nrab ntawm lub zog tseem ceeb thiab hauv av rau kev tiv thaiv. Lub transformer nyob nruab nrab ntawm kab N thiab kab PE, saib Daim Duab d hauv qab no.
Kev tiv thaiv kab hluav taws xob sab nraud ib theem (saib Daim Duab 7)
Ib lub transformer sab nraud (neutral pole transformer lossis ib puag ncig current transformer) yog muab rau tus neeg siv ua ib qho khoom siv. Tus neeg siv teeb tsa nws rau hauv lub busbar ntawm nws tus kheej, thiab txuas qhov kev sib txuas (ntev yog 2m) rau cov secondary terminal blocks # 25 thiab # 26 ntawm lub circuit breaker.
Kev faib theem
Siv los ua kom lub zog rwb thaiv tsev ntawm cov busbars (rau hom tub rau khoom).
