Peb-ncej Circuit Court breaker: ib tug txheej txheem cej luam, hom, yam ntxwv thiab kev txheeb xyuas

Circuit Court tej fais fab yog tsim los cuam tshuam qhov hluav taws xob network thaum tau siab tshaj lub kev khiav hauj lwm tam sim no thiab luv luv circuits. Lawv tiv thaiv cov xov thiab kev cob cog rua rau nws los ntawm cov kev pab tshooj thiab muaj ib tug mus rau plaub tug. Peb-ncej Circuit Court breaker yog tsim los tiv thaiv cov peb theem Circuit Court los yog nyob rau tib lub sij hawm peb-theem thaiv. Yog hais tias ib tug ntawm cov kab ntawm cov kev huam yuaj, yog neeg xiam tam sim ntawd peb tug.

Tus ntaus ntawv daws li nram qab no paub tab:

• kev tiv thaiv network seem;
• neej puas tiv thaiv Circuit Court feem;
• qhov tseeb kev xaiv ntawm cov kev tiv thaiv ntawm tsis tau tso cai mus ncig ua si.

yam ntxwv ntawm

Lub ntsiab yam ntxwv ntawm lub tshuab - nws yog nyob tawg peev xwm thiab txiav-off ceev. Lawv ua hauj lwm los ntawm ob shutdown mechanisms: thermal thiab electromagnetic. Tus thawj yuav qhib rau hauv Circuit Court thaum ib tug luv luv Circuit Court, thiab lub thib ob - qhov kev txiav txim ntawm tas mus li tam sim no tau siab tshaj lub nominal. Rab phom yuav siv tau raws li ib tug mus ntawm ib tug tswj tseem ceeb.

Nyob tawg peev xwm

Feature nqi qhia lub siab tshaj plaws permissible luv luv-Circuit Court tam sim no uas tus tes hloov qhov yog tau disconnect tus xov mus pab kiag li lawm kev cob cog rua thereto tsawg kawg ib zaug. Nws yog qhia rau lub tsev ntawm lub tshuab thiab muaj ib tug nqi ntawm:

• 4,5 kÅ - mus tiv thaiv luv luv Circuit Court teb kab ntawm lub khoom ntawm ntiag tug, nyob qhov twg kuj kab loads ntawm lub substation tsis muaj hwjchim loj dua 0.05 ohms;
• 6 kÅ - tiv thaiv lub thaj sector thiab pej xeem qhov chaw, qhov chaw uas txoj kab kuj yog tsis qis tshaj li 0,04 ohms;
• 10 kÅ - siv los mus tiv thaiv kev puas tsuaj rau lub hwj chim kav ib ncig ntawm lub substation.

pom zoo hloov kho 6 kÅ qauv rau kev circuits.

Lub sij hawm-tam sim no cov yam ntxwv

Thaum sis tsis ncaj zog noj tshwm sim los ntawm load variation thiab enabling los yog tu-ncua Circuit Court pab kiag li lawm, tej zaum yuav muaj cuav positives tiv thaiv pab kiag li lawm vim tau siab tshaj lub nyob tam sim no. Yuav kom txo tau qhov yuav ntawm triggering siv cav tov nrog predetermined lub sij hawm-tam sim no yam ntxwv (BTX). Parameter qhia lub cutoff lub sij hawm ntawm ib tug tej yam piv tam sim no mus rau lub nominal tus nqi. BTX yog li nram qab no.

1. B - ib tug electromagnetic txawv tebchaws chav tsev mus ua si tom qab 0,015 vib nas this ntawm txoj hlua peb nce nyob rau hauv tam sim no nrog rau kev hwm rau cov nominal tus nqi.
2. C - lub feem ntau cov yam ntxwv thaum kev tiv thaiv yog txhais los ntawm nce lub nominal tus nqi 5 lub sij hawm. Machine yog haum rau teeb pom kev zoo thiab cov khoom siv muaj mob loj tsawv inrush currents.
3. D - machines tsim rau cov loj inrush currents, xws li thaum lub fais boiler, electric motors thiab lwm yam peb-theem kiag li lawm. Mas siv nyob rau hauv qhov kev lag luam.

Txheej txheem cej luam tej fais fab

Tshuab yog kev cob cog rua ntawm lub hwj chim qhov twg los thiab thaiv, uas yuav tsum tau muaj kev tiv thaiv. Peb-ncej Circuit Court breaker comprises peb hu officers, qhov twg txhua yog kev cob cog rua nyob rau hauv series nrog ib tug thermal thiab electromagnetic txawv tebchaws units. Tsis Siv Neeg theem lov tes taw xwb tsis rhuav hauv nruab nrab, uas yog tsis cob cog rua rau nws. Yog hais tias koj xav tau los disconnect hauv nruab nrab hlau, siv plaub-ncej qauv. Feem ntau, lawv yog siv nyob rau hauv lub ntsiab tswv yim.

Lub qhov thiab lwm lub tsev siv cov cav tov ntawm cov chav kawm ntawv rau hauj sim loads. Tus tam sim no lub dag lub zog yog xaiv raws li lub hwj chim ntawm tus kev cob cog rua pab kiag li lawm, qhov twg rau lub chaw pib yog ob zaug cov denomination los mus tshem tawm cuav positives.

Faib cov khoom IEK npe, ntawm EKF, DEK, INTES thiab "contactor". Domestic cov khoom muaj txaus cia siab rau thiab tus nqi tsim nyog. Siv lug machines nyob rau hauv lub 16 A thiab 25 A. Imports yog kim kim, tab sis zoo-paub tuam txhab uas muag yuav ua kev zoo siab thiab txhim khu kev qha cov qauv. Nyob rau tes hloov qhov tsis siv neeg peb-ncej nqi los ntawm zoo-paub tuam txhab uas muag tej zaum yuav sib txawv heev, tab sis nws yog ib yam zoo.

Tiv ntaus nrog peb-theem tam sim no yog thov rau ntawm lub tswv yim ntawm lub tsev thiab rau kev hwj chim cov cuab yeej nrog ib tug voltage ntawm 380 V, piv txwv li, ib tug tsis siv peb-ncej 100A mus.

Lub hwj chim no yuav tsum sib haum mus rau lub txee, yog hais tias nws sawv tom qab tus tes hloov qhov. Feem ntau nws yog tsis ntau tshaj 63 A. Ib haib dua peb-ncej Circuit Court breaker yog siv nyob rau hauv qhov kev lag luam.

Los ntawm lub tswv yim thiab tswv yim ntawm tej electricians nws hais ntxiv hais tias cov cav tov nrog denominations overestimated nyob rau hauv txhua rooj plaub yuav siv tsis tau. Qhov no yog ib tug uas yuav muaj hluav taws los tsis ua hauj lwm ntawm lub twj paj nruag.

Cov plaub-hlau peb theem thiab pes tsawg yog txhab khoom mus rau ua hauj lwm lub tsev. Lawv tsis tshua muaj siv khoom nyob rau ntawm 380 V. Cov theem nyob rau hauv lub tis rau vaj huam sib luag yog sib cais. Qhov no yields 3 kab nrog ib tug voltage ntawm 220 V.

Qhov kom zoo dua ntawm multi-ncej machines yog cov muaj peev xwm ib txhij tswj ntau yam kab. By txhim kho ib qho automatic peb-ncej hloov 25A peb-unit coj hwj chim tswj yuav nqa tawm nyob rau hauv txhua tus neeg kab. Nyob rau hauv cov kev tshwm sim ntawm ib tug luv luv Circuit Court nyob rau hauv ib tug ntawm lawv kaw tag nrho ib zaug. Feem ntau, nyob rau txhua txoj kab rau nruab ntxiv ib leeg-theem Circuit Court tej fais fab. Thaum ib tug ntawm lawv tsis ua hauj lwm theem, uas tsub kom system ntseeg.

BA series cov cav tov

Domestic machines ua series AE thiab BA. Tus thawj hom yog obsolete, thiab nws yog tsis tshua muaj siv. Nws muaj tsawg zog ntawm lub cev, cov tsis muaj kev twb kev txuas mus rau lub DIN-rail. Rau domestic daim ntaub ntawv zoo suited khoom series VA payment rau currents mus txog 63 A, yam ntxwv B, C, D, thiab lub tawg peev xwm ntawm 4.5 kÅ.

Domestic peb-ncej Circuit Court tej fais fab VA siab raws li niaj hnub yuav tsum tau, thaum ua kom tus nqi considerably qis tshaj mas ua qauv.

Raws li heev heev xyuas, mas qauv yuav tsum tau meej nyob rau hauv xws siab nqi. Tab sis lawv misfire, tab sis yog tsawg domestic qauv.

xaus

Peb-ncej Circuit Court breaker yog ib qho tseem ceeb ib feem ntawm ib lub tsev lub qhov hluav taws xob system. Xaiv kim qauv, nws yuav tsum tau borne nyob rau hauv lub siab hais tias tus so ntawm cov khoom yuav tsum tau rau tib theem: thaiv, keyboards thiab nyob, hlws ris thawv, teeb pom kev zoo fixtures.

Lub ntsiab yam ntxwv ntawm cov cav tov yeej ib txwm muaj nyob rau hauv sab ntawm lub vaj tse nyob. Lawv raug xaiv raws li nyob rau hauv hlau loj thiab qhov ntau ntawm cov kev cob cog rua load.
