Ib lub tshuab hluav taws xob yog lub tshuab hloov hluav taws xob uas tso cai rau hluav taws xob tam sim no thiab tua lub zog thaum nws tshaj tus nqi nominal. Nws pab tiv thaiv hluav taws xob circuits los ntawm overloads. Ib qho hluav taws xob hluav taws xob ib leeg muab kev tiv thaiv rau ib lub xaim xwb.

Tsim thiab lub hauv paus ntsiab lus ntawm kev ua haujlwm

Cov yam ntxwv tseem ceeb ntawm lub Circuit Court breaker yog qhov ntsuas thiab nrawm nrawm. Lub tshuab ib-ncej yog ua los ntawm ob lub tshuab: thermal thiab electromagnetic tso tawm. Thawj disconnects lub Circuit Court nyob rau hauv cov kev tshwm sim ntawm ib tug ntxiv load rau lub sij hawm ntev, thiab lub thib ob - instantly, nyob rau hauv cov ntaub ntawv ntawm ib tug luv luv Circuit Court.

Cov khoom siv tiv thaiv thermal yog lub phaj bimetal. Thaum ib qho tam sim no siab tshaj qhov siab tshaj plaws tau dhau los ntawm nws, nws maj mam ua kom sov thiab khoov, thawb lub zog uas tig tawm lub tshuab. Tom qab txias, lub phaj rov qab mus rau nws qhov chaw, thiab qhov hloov pauv tau npaj ua haujlwm dua. Txhawm rau muab nws ua haujlwm, koj yuav tsum txuas nws manually.

Ib qho khoom siv hluav taws xob muaj cov kauj nrog ibtub ntxhais. Thaum ib qho luv luv Circuit Court tam sim no dhau los ntawm winding, electromagnetic teb tshwm sim uas txav cov tub ntxhais, uas tig tawm lub tshuab. Hauv qhov no, lub zog tiv tauj qhib, de-energizing lub circuit. Txij li thaum ib tug loj tam sim no dhau los ntawm lawv, ib tug arc tshwm sim. Nws nkag mus rau hauv arc chute, qhov chaw uas cov hlau sib txuas yog nyob. Nrog lawv pab, lub arc tawg thiab tawg.

Lub tshuab kuj tseem siv los ua qhov hloov pauv los ntawm kev tig lub pob qhov rooj.

Daim ntawv thov ntawm ib tus ncej Circuit Court breaker

Kev xaim hauv chav tsev cov ceg hauv ob peb pawg. Kev sib txuas ntawm ib leeg-ncej tshuab yog tsim los ntawm kev tawg ntawm theem hlau. Nws yog mounted rau ib tug DIN rail, thiab ib tug fais fab hlau yog muab tso rau hauv nws lub qaum clamp. Cov hlau yuav tsum tau tiv thaiv yog txuas nrog lub davhlau ya nyob twg qis. Yog hais tias cov xov hlau raug nias nrog screws, lawv yuav tsum tau nruj me ntsis quab yuam.

Raws li txoj cai, cov terminals sab saud ntawm ib leeg-ncej Circuit Court breakers yog txuas nrog lub hwj chim mov los ntawm ib tug zuag, thiab cov nram qab terminals yog wired rau hauv pab pawg neeg. Muaj ntau qhov chaw rov ua dua tuaj yeem teeb tsa.

Marking

Cov kab hluav taws xob muaj cov cim cim uas nyeem los ntawm sab saum toj mus rau hauv qab.

Lub cev ntawm lub cuab yeej muaj qhov tseem ceeb ntawm nws qhov tseem ceeb:

• trademark - EKF;
• series naj npawb - BA47-29;
• yam ntxwv "C" thiab ntsuas tam sim no rau lub tshuab ib-ncej - 25A;
• ntsuas voltageLub hwj chim - 230/415V;
• siab tshaj qhov tso cai luv luv-circuit breaking tam sim no - 4500 A;
• tam sim no txwv cov chav kawm - 3.

Koj tuaj yeem txheeb xyuas cov chaw tsim khoom los ntawm hom. Nws raug nquahu kom xaiv cov vending tshuab los ntawm cov npe nrov: Legrand, ABB, IEK, EKF, thiab lwm yam.

Daim ntawv sau rau ntawm lub tshuab 230/415 V txhais tau tias lub cuab yeej muaj peev xwm ua haujlwm hauv ib-theem thiab peb-theem tes hauj lwm. Feem ntau cov khoom siv hauv tsev xaim muaj peev xwm.

Rated tam sim no yog tus nqi tam sim no uas lub tshuab yuav tsis ua haujlwm ntev. Yog tias nws nce los ntawm 13%, nws yuav tua hauv ib teev. Qhov loj dua tus nqi ntawm qhov tsis tu ncua ntws tam sim no, kev ua haujlwm sai dua. Lub hom phiaj tseem ceeb ntawm lub tshuab yog los tiv thaiv overheating ntawm cov hlau thaum lub load txuas. Nws yog ib qho tseem ceeb uas tam sim no tso cai rau tus neeg xyuas pib ntau dua li qhov ntsuas ntawm lub cuab yeej, thiab tsis hloov pauv.

Lub sijhawm-tam sim no tus yam ntxwv "C" txhais tau hais tias kev ua haujlwm ntawm ob qho tib si tripping mechanisms yuav tshwm sim tom qab nce tsib npaug ntawm qhov ntsuas tam sim no. Nws yog tsim rau cov teeb pom kev zoo thiab cov khoom siv hauv tsev feem ntau. Yog tias muaj lub tshuab tsis siv neeg nrog cov yam ntxwv zoo li no hauv kev nkag, tom qab ntawd hauv chav tsev vaj huam sib luag nws yog qhov tsim nyog los nruab ib lub cuab yeej nrog tus yam ntxwv "B" ntawm lub ntsiab lus nkag. Qhov no txhais tau tias nrog rau tag nrho lwm yam zoo tib yam, nws yuav ua hauj lwm sai dua. Tom qab ntawd koj tsis tas yuav khiav mus rau qhov nkag thiab qhib lub tshuab rau ntawd. Xaiv cov cuab yeej tsim nyog nrog tus yam ntxwv zoo kom ntseeg tau qhov kev xaiv mus txawv tebchaws.

Qhov siab tshaj plaws tso cai tawm mus tam sim no qhia nws tus nqi siab tshaj plaws ntawm qhov twglub tshuab tuaj yeem tua tsawg kawg ib zaug.

Ntau tus ncej

Yog tias koj xaiv lub tshuab ib-ncej lossis ob-ncej, nws yog qhov tseem ceeb rau qhov chaw nruab. Ib tug ob-terminal network yuav tsum tau ntsia rau ntawm lub ntsiab lus ntawm lub tsev ntaub thaiv npog. Qhov no yuav cia siab rau de-energize lub tsev thaiv thaum kho, thaum lub sij hawm yuav tsum tau disconnected nrog rau qhov nruab nrab. Thaum 2 xov hlau nkag mus rau hauv tsev, koj tuaj yeem nruab ib lub tshuab tsis siv neeg nrog ib tus ncej. Nyob rau hauv lub xub ntiag ntawm ib tug grounding conductor, ib tug ob-ncej input tshuab yog ntsia.

Ib lub tshuab ib leeg txuas nrog txhua ceg ntawm lub tsev network nrog rau RCD.

Yog hais tias lub tsev yog siv los ntawm peb-theem Circuit Court, lub tshuab plaub-ncej yuav tsum tau nruab rau ntawm lub ntsiab lus nkag.

ib-pole tshuab: nqe

ib leeg-ncej tshuab yog pheej yig dua li lwm tus hauv kab nrog ntau tus ncej. Cov khoom lag luam hauv tsev tuaj yeem yuav rau 40-50 rubles, thaum cov khoom lag luam txawv teb raug nqi 150-200 rubles. Nws yog ib qho tseem ceeb uas yuav tau xaiv cov khoom siv raws li qhov zoo-tus nqi piv, thiab tsis yog cov uas pheej yig dua.

Yuav yuam kev thaum xaiv tshuab

Thaum xaiv lub tshuab hluav taws xob, cov neeg siv ua yuam kev ntau.

1. Tsom ntsoov rau kev siv hluav taws xob tag nrho es tsis txhob tiv thaiv cov xaim hluav taws xob ntau dhau. Kev txhim kho lub tshuab muaj zog ntawm cov xaim tsis muaj zog ua rau nws muaj cua sov. Nws yog ib qho tseem ceeb uas yuav tau xaiv cov cuab yeej raws li cov seem xaim.
2. Feem ntau tib lub tshuab tau nruab rau ntawm txhua kab, vim qee qhov ntawm covlawv overloaded. Cov qhov (sockets) xav tau 25 A tiv thaiv, thiab teeb pom kev zoo xav tau 16 A. Cov kab uas ua rau lub chaw nres tsheb tuaj yeem thauj khoom hnyav nrog cov cuab yeej muaj zog. Ntawm no yog qhia kom nruab lub tshuab ntawm 32 A.
3. Tsis txhob xaiv cov qhov raws li tus nqi. Nws yog qhov zoo dua los yuav cov khoom lag luam uas muaj npe nrov, qhov zoo yog lav.

Zaj lus

Txhawm rau xaiv lub tshuab ib leeg-ncej uas xav tau yam tsis muaj qhov yuam kev, koj yuav tsum nkag siab cov cim sau rau ntawm rooj plaub ntawm sab xub ntiag. Cov yam ntxwv ntawm cov cuab yeej raug xaiv nyob ntawm seb hom kev sib txuas ntawm kev thauj khoom thiab qhov chaw hla ntawm cov xaim.
