Circuit Court breaker lossis Circuit Court breaker yog ib qho khoom siv hloov pauv uas ua cov khoom siv tam sim no nyob rau hauv ib qho xwm txheej hauv Circuit Court thiab txiav tawm cov khoom siv hluav taws xob los ntawm lub mains mus rau cov neeg siv khoom thaum lub sij hawm luv luv lossis overload, koj tuaj yeem kuj tig lub Circuit Court rau thiab tawm manually.
Qhov sib txawv tseem ceeb ntawm lub tshuab bipolar thiab ib lub tshuab ib leeg yog qhov muaj lub automaton ob qho tib si hauv theem thiab ntawm xoom, uas yog, ntawm ob tug ncej. Ntxiv mus, thaum disconnected, ob theem thiab xoom yog ib txhij disconnected, ua tsaug rau cov sib cocking kov. Nws yog siv rau kev teeb tsa ntawm ib-theem Circuit Court. Rau peb-theem Circuit Court, 3- thiab 4-ncej Circuit Court breakers yuav tsum tau siv.
Scope of application
- Raws li kev taw qhia txog kev ntsuas hluav taws xob. Nov yog daim ntawv thov nrov tshaj plaws. Nrog rau kev sib txuas ib txhij ntawm theem thiab xoom, kev nyab xeeb siab tshaj plaws yog ua kom muaj kev nyab xeeb thaum ua haujlwm hauv Circuit Court, vim tias muaj kev ua tiav tag nrho. Tsis tas li ntawd, raws li cov cai tshiab ntawm Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob (clause 6.6.28, clause 3.1.18), kev ua haujlwm ntawm ib leeg-ncej tsis siv neeg tshuab ntawm cov tswv yim raug txwv.
- Tiv thaiv ib pab pawg neeg siv hluav taws xob sib cais. Disabling lub tshuab ob-ncejyuav tiv thaiv kev ua haujlwm ntawm RCD (cov cuab yeej seem tam sim no - tsim los tiv thaiv qhov sib txawv tam sim no) thaum muaj kev sib cuag tsis raug ntawm xoom thiab theem thaum kho ua haujlwm hauv circuits hauv qab load. Nws kuj tseem pab txhawb kev tshawb nrhiav ib ceg nrog kev ua haujlwm tsis zoo thaum RCD tshwm sim los ntawm cov dej ntws mus rau hauv av.
- Kev tiv thaiv thiab tswj cov kab hluav taws xob thaum txuas hluav taws xob. Piv txwv li, thaum lub tshuab hluav taws xob txuas nrog, ib theem tau muab rau cov khoom cua sov los ntawm ib tug ncej ntawm lub tshuab, thiab ib theem yog nkag mus rau lub kiv cua los ntawm lwm tus ncej. Yog tias ib qho khoom siv kaw, lwm qhov yuav kaw ib yam nkaus, tiv thaiv lub tshuab cua sov kom tsis txhob ua kom txias.
Qhov zoo tshaj ntawm cov cav ntoo ib leeg
Cia peb xav txog qhov xwm txheej uas ib tus neeg sib xyaw ua ke nrog xoom. Tom qab ntawd, thaum lub tshuab hluav taws xob ib leeg raug tua, cov kab xoom raug txiav, thiab cov theem tseem nyob hauv Circuit Court. Ib tug neeg, xav tias nws tau tiv thaiv nws tus kheej los ntawm kev kaw lub tshuab, pib ua haujlwm thiab tau txais hluav taws xob poob siab. Txhawm rau tiv thaiv qhov no tshwm sim, tom qab kaw lub tshuab ib leeg, koj yuav tsum tau kuaj xyuas qhov tsis muaj qhov hluav taws xob hauv Circuit Court nrog qhov ntsuas. Tab sis tseem nws yog qhov txhim khu kev qha ntau dua los siv lub tshuab ob-ncej, uas yuav ua kom lub zog tag nrho ntawm lub voj voog.
Nyob rau hauv rooj plaub thaum RCD tau tripped, nws yog ib qho tsim nyog yuav tau nrhiav qhov txhaum hauv Circuit Court. Ua ntej tshaj plaws, tag nrho cov khoom siv hluav taws xob los ntawm lub qhov (sockets) raug tua. Yog tias qhov no tsis ua haujlwm, cov ceg hluav taws xob tau raug hloov mus rau hauv ib ntus, tab sis ob qho tib si xoom thiab theem yuav tsum raug txiav. Lub tshuab ib-ncej tsis muab lub sijhawm zoo li no. Koj yuav tsum poob xoom ntawm lub npav, uas yog qhov teeb meem, vim nws yuav tsum muaj lub suab hu kom pom cov hlau zoo. Ob tug ncej Circuit Court breaker ua haujlwm zoo heev ntawm qhov no.
Yog li cov txiaj ntsig:
- Kev nyab xeeb - hluav taws xob hluav taws xob tawg tag.
- Kev daws teeb meem yooj yim.
Qhov tsis zoo ntawm kev siv ua ntej ib leeg-ncej tshuab
Qhov tseeb, muaj ob peb yam tsis txaus:
- Nqi - ob-ncej kim dua ib tus ncej.
- Ergonomic - siv ob zaug ntau qhov chaw hauv vaj huam sib luag hluav taws xob.
- Tus nqi ua haujlwm thaum lub sijhawm teeb tsa - cov xaim nruab nrab tsis tau muab tso rau hauv lub tsheb npav, tab sis txhua tus pib hauv nws lub tshuab.
- Qhov tsis tuaj yeem ntawm kev siv tus qauv faib cov npav - "combs", tsis yog lawv koj yuav tau siv jumpers.
Tsis siv neeg ntaus ntawv
Lub Circuit Court breaker yog cov ntaub ntawv yas uas muaj kev sib cuag thiab tus kov rau / tawm. Sab hauv yog qhov chaw ua haujlwm. Ib tug stripped hlau yog muab tso rau hauv lub terminals thiab clamped nrog ib tug ntsia hlau. Thaum cocked, lub zog tiv tauj raug kaw - txoj hauj lwm ntawm tus kov yog "On". Tus kov yog txuas nrog lub cocking mechanism, uas, nyob rau hauv lem, txav lub zog hu. Electromagnetic thiab thermal splitters muab kaw lub tshuab nyob rau hauv cov ntaub ntawv ntawm txawv Circuit Court tej yam kev mob. Lub arc chute tiv thaiv kev hlawv thiab tua cov arc sai. Cov pa hluav taws xob ua rau cov roj combustion tawm ntawm lub casing.
daim duab sib txuas
Nws tau thov kom xav txog daim duab txuas ntawm lub tshuab ob-ncej.
Ntawm BA 47-63 2/50A yog ib qho kev taw qhia ob-ncej tshuab. Nws tag nrho de-energizes tag nrho Circuit Court yog tias tsim nyog. Ib lub 'meter' thiab RCD txuas nrog tom qab nws. Tom ntej no, ib daim duab sib txuas rau ib tug xov tooj ntawm ib tug ncej Circuit Court breakers yog siv. Lawv tsuas yog ntsia tau rau ntawm cov kab hluav taws xob theem, thiab cov neeg nruab nrab nruab nrab raug faib los ntawm lub npav.
Muaj ib lub tswv yim rau kev sib txuas ntawm ob tug ncej automata, txhua tus tiv thaiv nws tus kheej ceg.
Ua ntej, RCD txuas nrog ntawm cov tswv yim, tom qab ntawd ob kab ntawm ob-ncej keyboards. Cov xaim nruab nrab yog cim rau hauv xiav, theem xaim yog xim liab, thiab cov xaim hauv av, faib siv lub tsheb npav hauv av, yog daj. Yog li, txhua ceg ntawm lub voj voog raug tiv thaiv.
Installation
Yuav ua li cas txhawm rau txhim kho cov hluav taws xob hluav taws xob hauv vaj huam sib luag? Ua ntej, din-rails yog screwed rau hauv nws nrog tus kheej-tapping screws - cov no yog hlau daim hlau, uas tag nrho cov tshuab tsis siv neeg thiab RCDs yog ces txuas. Qhov ntev ntawm DIN rail tuaj yeem hloov kho nrog lub hacksaw. Tsis tas li ntawd, cov terminals faib-cov log tsheb yog txuas nrog cov ntaub thaiv npog. Lawv tuaj yeem yog rau cov xov hlau nruab nrab thiab cais rau hauv av xaim. Kev teeb tsa busbar niaj hnub tso cai rau koj los txhim kho lawv ncaj qha rau ntawm din rail.
Txhim kho lub tshuab ob-ncej ntawm DIN rail yog yooj yim heev. Nrog lub hau ntswj tiaj tus, koj yuav tsum rub tawm lub snap-on bracket nyob rau sab saum toj ntawm rooj plaub, txuas lub tshuab rau DIN rail thiab tso lub mount. Kev tshem tawm kuj ua tiav. Raws li txoj cai, lub tshuab taw qhia tau teeb tsa nyob rau sab laug sab sauv.
Tom ntej koj yuav tsum txuas cov xov hlau. Koj yuav tsum nruj me ntsis ua raws li lub tswv yim. Cov kab hluav taws xob nkag ntawm theem thiab xoom txuas nrog lub tshuab ob-ncej los ntawm saum toj, thiab cov xaim xaim raug coj mus rau hauv Circuit Court los ntawm hauv qab no. Nws yog ib qho tseem ceeb kom tsis txhob confuse: qhov nkag yog los ntawm saum toj no, qhov tawm yog los ntawm hauv qab no, txwv tsis pub lub tshuab yuav poob thiab yuav tsis ua nws functions.
Koj tuaj yeem ua ke cov tshuab siv cov jumpers ua los ntawm tooj liab hlau ntawm tib ntu hla raws li cov xaim hluav taws xob. Jumpers yuav tsum tau txuas ob-ncej tshuab ua ke. Thiab kuj nrog kev pab los ntawm combs - cov no yog cov log tsheb insulated, siv los txuas ib leeg-ncej tshuab.
Qhov kawg ntawm cov xov hlau raug stripped siv lub cuab yeej tshwj xeeb stripper lossis riam ntse. Tom qab ntawd lawv yog crimped nrog cable lugs nrog ib tug crimper tes cuab tam. Yog tias tsis muaj cov cuab yeej zoo li no, koj tuaj yeem yooj yim tin xaus nrog cov hlau soldering siv rosin thiab tin. Thaum txuas cov xov hlau rau cov cav tov, nws yog ib qho tsim nyog yuav tsum ua kom nruj cov bolts nrog lub hau ntswj kom tsis muaj zog tiv tauj tsis ua rau cua sov thiab puas rau cov khoom siv hluav taws xob.
Cov xaim hauv av ib txwm mus dhau lub tshuab ncaj qha los ntawm tsheb npav hauv av. Cov kab nruab nrab txuas nrog lub npav xoom.
Marking
Kev saib xyuas tshwj xeeb yuav tsum tau them rau cov tshuab cim.
Cov cim tshwj xeeb yog siv rau ntawm lub cev ntawm cov tshuab:
- Rated tam sim no ntawm lub cuab yeej (hauv amps).
- Ntau pab pawg tam sim no (kev ua haujlwm tam sim no).
- siab tshajkev khiav hauj lwm tam sim no lossis luv luv tam sim no (hauv amps).
- Tam sim no txwv cov chav kawm (cov chav kawm siab dua, cov lus teb nrawm dua yog qhov luv luv).
- kos duab kos duab lossis daim duab kos duab ntawm lub cuab yeej.
- Machine series.
- Rated voltage uas lub tshuab yuav tsum tau siv.
Xaiv tshuab
Ua ntej koj yuav tsum xam tus nqi ntawm qhov ntsuas tam sim no rau koj lub network. Qhov no tuaj yeem ua tiav siv cov qauv (Ohm txoj cai):
I=P/U where:
I - ntsuas tam sim no hauv amperes "A".
P - lub zog ntawm txhua yam khoom siv (ntxiv lub zog) hauv watts "W".
U - mains voltage hauv volts "V" (tsuas yog 220 V). Koj yuav tsum xaiv lub tshuab nrog tus nqi siab tshaj ntawm qhov ntsuas tam sim no.
Tsis tas li ntawd, kev xaiv lub tshuab raws li tus nqi ntawm lub sijhawm ntev tso cai tam sim no yuav tsum tau ua, nyob ntawm tus yam ntxwv ntawm cov xaim cable. Cov kev cai rau kev teeb tsa cov khoom siv hluav taws xob muaj cov ntxhuav ntawm kev suav. Qhov loj ntawm cov kab hluav taws xob, qhov siab dua qhov kev tso cai txuas ntxiv tam sim no.
