Tsis siv neeg hloov pauv yog tsim los tua hluav taws xob sib txuas thaum muaj kev khiav hauj lwm tam sim no thiab luv luv. Lawv tiv thaiv cov xaim hluav taws xob thiab cov neeg siv khoom txuas nrog nws los ntawm overloads thiab muaj los ntawm ib mus rau plaub tus ncej. Peb-ncej Circuit Court breaker yog tsim los tiv thaiv peb-theem Circuit Court lossis peb-theem ib-theem thaiv tib lub sijhawm. Yog tias muaj xwm txheej tshwm sim ntawm ib qho ntawm cov kab, peb tus ncej raug kaw ib zaug.
Lub cuab yeej daws cov haujlwm hauv qab no:
- kev tiv thaiv ntawm ntu network;
- tiv thaiv kev tawg ntawm ib ntu ntawm cov saw;
- nrog kev xaiv raug, tiv thaiv kev kaw tsis raug cai.
Ntse
Cov yam ntxwv tseem ceeb ntawm cov tshuab yog qhov ntsuas qhov muaj peev xwm tawg thiab qhov txiav nrawm. Lawv tau tshwm sim los ntawm ob lub tshuab kaw: electromagnetic thiab thermal. Thawj qhib lub Circuit Court thaum lub sij hawm luv luv Circuit Court, thiab qhov thib ob - los ntawm qhov kev txiav txim ntawm ib tug nruam load tshajnpe. Lub tshuab tuaj yeem siv los ua kev hloov pauv los ntawm tus yuam sij tswj.
Rated tawg peev
Tus yam ntxwv qhia tau hais tias tus nqi ntawm qhov siab tshaj plaws tau tso cai luv luv tam sim no, ntawm qhov hloov pauv tau tuaj yeem de-energize cov xaim nrog cov khoom siv txuas nrog nws tsawg kawg ib zaug. Nws tau qhia rau ntawm lub cev ntawm lub tshuab thiab muaj cov ntsiab lus hauv qab no:
- 4, 5 kA - rau kev tiv thaiv luv luv ntawm cov kab hluav taws xob ntawm cov tsev ntiag tug, qhov twg cov kab tiv thaiv los ntawm lub chaw nres tsheb mus rau cov khoom thauj tsis pub tshaj 0.05 Ohm;
- 6 kA - tiv thaiv thaj chaw nyob thiab cov chaw pej xeem uas cov kab tsis kam qis dua 0.04 Ohm;
- 10 kA - siv los tiv thaiv kev puas tsuaj rau cov kab hluav taws xob ze ntawm lub chaw nres tsheb.
Rau cov hluav taws xob hauv tsev, nws raug pom zoo kom siv 6 kA kev hloov kho qauv.
Tim sijhawm-tam sim no tus yam ntxwv
Yog tias qhov kev siv hluav taws xob tsis sib xws tshwm sim los ntawm kev hloov pauv thiab hloov pauv lossis tawm ntawm cov khoom siv hluav taws xob, kev mus ncig tsis raug ntawm cov cuab yeej tiv thaiv yuav tshwm sim vim muaj ntau tshaj qhov ntsuas tam sim no. Txhawm rau txo qhov tshwm sim ntawm lawv txoj haujlwm, automata nrog cov yam ntxwv ntawm lub sijhawm tam sim no (VTX) tau siv. Tus parameter qhia lub sij hawm txiav tawm ntawm ib qho piv txwv ntawm tam sim no rau tus nqi nominal. VTX muaj raws li nram no.
- B - cov khoom siv hluav taws xob tso tawm tom qab 0.015 vib nas this nrog qhov nce peb npaug ntawm tam sim no cuam tshuam rau tus nqi nominal.
- C - tus yam ntxwv tshaj plaws, thaum muaj kev tiv thaiv tshwm sim thaum qhov ntsuas tau nce 5 zaug. Cov cav tov yog tsim rau cov teeb pom kev zoo thiab cov khoom siv hauv tsev nrog rau nruab nrabpib tam sim no.
- D - cov cav tov yog tsim los rau siab pib tam sim no, piv txwv li, thaum tig rau hluav taws xob boiler, hluav taws xob motors thiab lwm yam peb-theem li. Feem ntau siv hauv kev lag luam.
Circuit Breakers Overview
Lub tshuab txuas ntawm qhov tam sim no thiab cov xaim hluav taws xob, uas yuav tsum tau tiv thaiv. Peb-ncej Circuit Court breaker muaj peb qhov kev sib cuag, qhov twg txhua khub txuas nrog cov khoom siv thermal thiab electromagnetic tawm. Lub tshuab disconnects tsuas yog cov theem, yam tsis muaj kev cuam tshuam qhov nruab nrab, uas tsis txuas nrog nws. Yog tias muaj qhov xav tau los txiav cov kab nruab nrab, plaub-ncej qauv siv. Feem ntau lawv yog siv rau ntawm lub ntsiab lus nkag.
Hauv cov tsev thiab cov tsev ntiag tug, chav kawm C tshuab yog siv rau cov khoom nruab nrab. Lub zog tam sim no raug xaiv raws li lub zog ntawm cov khoom siv txuas nrog, qhov twg tus nqi pib yog ob npaug ntawm tus nqi nominal thiaj li tsis suav nrog qhov tsis zoo.
Cov khoom lag luam IEK, EKF, DEK, INTES thiab "Kontaktor" raug faib. Cov khoom siv hauv tsev muaj kev ntseeg txaus thiab tus nqi tsim nyog. Cov tshuab tsis siv neeg rau 16 A thiab 25 A tau siv dav, cov khoom lag luam tuaj yeem kim dua, tab sis cov tuam txhab paub zoo tsim cov qauv zoo thiab txhim khu kev qha. Rau qhov hloov pauv peb-ncej tsis siv neeg, tus nqi ntawm cov tuam txhab paub zoo tuaj yeem sib txawv heev, tab sis nws zoo ib yam nrog qhov zoo.
Cov cuab yeej tiv thaiv nrog peb-theem tam sim no yog siv rau ntawm qhov nkag mus rau hauv tsev thiab rau kev siv lub tshuab ua haujlwm nrogvoltage 380 V, piv txwv li, peb-ncej tsis siv neeg hloov 100A.
Lub zog no yuav tsum sib haum mus rau lub ntsuas, yog tias nws yog tom qab hloov pauv. Feem ntau nws tsis ntau tshaj 63 A. Ib qho hluav taws xob hluav taws xob peb-ncej hluav taws xob ntau dua yog siv hauv kev lag luam.
Los ntawm kev tshuaj xyuas thiab cov lus qhia ntawm cov kws paub txog hluav taws xob, nws ua raws li cov tshuab uas muaj qhov ntsuas ntsuas siab tshaj yuav tsum tsis txhob siv. Qhov no hem ua rau hluav taws kub lossis khoom siv tsis ua haujlwm.
Plaub-core xaim nrog peb theem thiab xoom ua haujlwm raug coj mus rau cov tsev nyob. Lawv tsis tshua siv cov cuab yeej tsim los rau 380 V. Cov theem hauv cov keyboards sib cais. Qhov no ua rau 3 kab sib cais nrog qhov hluav taws xob ntawm 220 V.
Qhov kom zoo dua ntawm ntau tus ncej hluav taws xob yog lub peev xwm tswj tau ob peb kab tib lub sijhawm. Los ntawm kev txhim kho qhov tsis siv neeg peb-ncej 25A hloov ntawm peb cov khoom siv ntawm lub zog tsim nyog, nws muaj peev xwm tswj tau txhua txoj kab. Yog hais tias ib tug luv luv Circuit Court tshwm sim ntawm ib tug ntawm lawv, tag nrho cov ntawm lawv yuav tua ib zaug. Feem ntau, ntxiv ib-theem hloov pauv tau nruab rau ntawm txhua kab. Yog tias ib qho ntawm lawv ua tsis tiav, peb theem ib yuav ua haujlwm, uas ua rau muaj kev ntseeg siab ntawm qhov system.
BA series machines
Cov tshuab hauv tsev yog tsim nyob rau hauv AE thiab BA series. Thawj hom yog siv tsis tau thiab tsis tshua siv. Nws muaj lub cev tsis muaj zog, tsis muaj kev sib txuas rau DIN rail. Zoo dua rau kev siv hauv tsevCov khoom tsim nyog ntawm VA series, ntsuas rau tam sim no txog 63 A, yam ntxwv B, C, D thiab tawg peev xwm ntawm 4.5 kA.
Lub tsev peb-ncej tsis siv neeg VA hloov ua tau raws li cov kev xav tau niaj hnub no, thaum muaj tus nqi qis dua cov qauv txawv teb chaws.
Raws li kev tshuaj xyuas ntau, cov qauv tuaj txawv teb chaws ntawm tus nqi siab yuav tsum yog qhov zoo tagnrho. Tab sis lawv misfire, txawm tias tsawg dua li cov qauv hauv tsev.
Zaj lus
Lub tshuab hluav taws xob peb-ncej yog ib feem tseem ceeb ntawm cov hluav taws xob hauv tsev. Thaum xaiv cov qauv kim, koj yuav tsum coj mus rau hauv tus account tias tag nrho lwm yam khoom siv yuav tsum yog tib theem: thaiv, hloov thiab qhov (sockets), hlws ris thawv, teeb pom kev zoo fixtures.
Cov yam ntxwv tseem ceeb ntawm cov tshuab yog ib txwm nyob ntawm rooj plaub ntawm sab xub ntiag. Lawv raug xaiv los ua tus lej hla ntawm cov xaim thiab qhov loj ntawm qhov txuas txuas.
