Lub hli tas los no, tus tswv ntawm lub chaw tsim khoom me me, Mr. Carter, tau ntsib teeb meem nyuaj siab: nws lub chaw ua haujlwm lub teeb pom kev zoo tau tawg ntau zaus, thiab cov khoom siv hluav taws xob txawm tias puas tsuaj qee zaum. Tom qab caw tus kws hluav taws xob los tshuaj xyuas, qhov ua rau hauv paus yooj yim heev - nws tau teeb tsa 1P circuit breakers yuam kev hauv lub voj voog fais fab loj uas xav tau kev tiv thaiv 2P. Qhov yuam kev no tsis yog tsuas yog cuam tshuam kev tsim khoom xwb tab sis kuj ua rau cov nqi kho tsis tsim nyog. Rau ntau tus kws ua hluav taws xob, cov neeg ua haujlwm yuav khoom, lossis cov tswv lag luam me,xaiv tus lej ncej zoo rau cov khoom siv hluav taws xob yog ib txoj haujlwm yooj yim tab sis tseem ceeb heevKev xaiv tsis raug tuaj yeem ua rau muaj kev phom sij rau kev nyab xeeb, cov khoom siv tsis ua haujlwm, lossis txawm tias kev kaw cov khoom tsim tawm. Niaj hnub no, peb yuav tshuaj xyuas cov xwm txheej ntawm kev siv 1P, 2P, 3P, thiab 4P circuit breakers kom pab koj xaiv tau qhov tseeb.
Ua ntej, "Tus lej Naj Npawb" ntawm Circuit Breaker yog dab tsi?
Tus lej ntawm lub tshuab hluav taws xob Circuit Court breaker yog hais txog tus lej ntawm cov ncej uas nqa tam sim no (conductive loops) uas nws muaj, uas txiav txim siab tus lej ntawm cov kab uas nws tuaj yeem tswj thiab txiav tawm tib lub sijhawm. Hais yooj yim, tus lej ntawm lub ncej ncaj qha cuam tshuam rau qhov ntau thiab tsawg ntawm kev tiv thaiv Circuit Court thiab hom kev muab hluav taws xob uas nws hloov kho rau. Tom ntej no, peb yuav rhuav tshem cov yam ntxwv thiab cov xwm txheej ntawm txhua tus lej ntawm lub ncej.
1P Circuit Breaker: Haum rau Ib-Theem Ceg Circuits nrog Kev Tiv Thaiv Yooj Yim
Nta:1P circuit breakers tsuas yog tswj thiab txiav cov xov hlau uas muaj sia (L xov hlau), yam tsis muaj kev koom nrog cov xov hlau nruab nrab (N xov hlau). Lawv muaj cov qauv yooj yim thiab pheej yig, feem ntau muab kev tiv thaiv overload thiab luv luv rau cov circuits ib theem.
Cov Xwm Txheej Thov:Nws yog siv dav hauv cov voj voog ib-theem ceg nrog lub zog tsawg thiab cov khoom thauj yooj yim, xws li cov voj voog teeb pom kev zoo hauv cov tsev nyob, cov voj voog qhov (socket) rau cov khoom siv hauv tsev me me (xws li teeb rooj, lub xov tooj them), thiab cov voj voog ib-theem ceg hauv cov chaw ua haujlwm teeb pom kev zoo.
2P Circuit Breaker: Zoo tagnrho rau Ib-Theem Main Circuits lossis Cov Loads Tseem Ceeb
Nta:Cov cuab yeej hluav taws xob 2P tuaj yeem tswj thiab txiav ob qho tib si cov xov hlau muaj sia thiab cov xov hlau nruab nrab tib lub sijhawm. Piv nrog 1P, lawv muaj ntau yam kev tiv thaiv ntau dua, zam kev phom sij ntawm hluav taws xob los ntawm cov xov hlau nruab nrab raug them vim muaj qhov tsis zoo.
Cov Xwm Txheej Thov:Haum rau cov voj voog fais fab loj ib theem (xws li lub qhov hloov tseem ceeb ntawm cov tsev neeg nyob), cov khoom siv tseem ceeb ib theem (xws li cua txias, cua sov dej, thiab tub yees nrog lub zog loj), thiab cov voj voog ib theem uas xav tau kev tiv thaiv kev nyab xeeb siab (xws li cov voj voog khoom siv kho mob hauv cov chaw kho mob me thiab cov voj voog ntsuas tseeb hauv cov chaw soj nstuam).
3P Circuit Breaker: Rau Peb-Theem Peb-Hlau System Industrial Loads
Nta:Cov cuab yeej hluav taws xob 3P yog tsim los rau cov tshuab fais fab peb-theem peb-xaim (tsis muaj xov hlau nruab nrab). Lawv tswj thiab txiav peb txoj xov hlau uas muaj sia nyob (L1, L2, L3) tib lub sijhawm, muab kev tiv thaiv overload thiab luv luv rau cov khoom siv peb-theem.
Cov Xwm Txheej Thov:Feem ntau siv rau hauv kev lag luam thiab kev tsuas, cov chaw ua haujlwm, thiab lwm qhov chaw uas muaj cov kab ke peb-theem peb-xaim. Cov khoom siv feem ntau suav nrog peb-theem asynchronous motors, peb-theem cua compressors, peb-theem hluav taws xob cub tawg, thiab lwm yam khoom siv peb-theem kev lag luam uas tsis xav tau cov xov hlau nruab nrab rau kev muab hluav taws xob.
4P Circuit Breaker: Haum rau Peb-Theem Plaub-Hlau System nrog Neutral Wire Protection
Nta:Cov cuab yeej hluav taws xob 4P tswj thiab txiav peb txoj hlua hluav taws xob thiab ib txoj hlua nruab nrab tib lub sijhawm, hloov kho rau peb theem plaub txoj hlua fais fab. Lawv tuaj yeem tiv thaiv cov voj voog thiab cov khoom siv thaum muaj qhov tsis zoo ntawm txoj hlua nruab nrab, ua kom muaj kev nyab xeeb ntawm tag nrho lub zog fais fab.
Cov Xwm Txheej Thov:Siv dav hauv cov tshuab fais fab peb-theem plaub-xaim uas xav tau kev tiv thaiv cov xaim nruab nrab, xws li lub qhov hloov tseem ceeb ntawm cov tsev lag luam (txhawb nqa ob qho tib si cov khoom siv peb-theem thiab cov khoom siv hauv tsev ib-theem), peb-theem plaub-xaim faib cov thawv hauv cov khw loj, cov chaw khaws ntaub ntawv nrog cov khoom sib xyaw peb-theem thiab ib-theem, thiab cov chaw tsim hluav taws xob tshiab (xws li photovoltaic thiab cov tshuab khaws cia hluav taws xob) uas xav tau kev tiv thaiv xaim nruab nrab.
Cov Lus Qhia Tseem Ceeb rau Kev Xaiv
1. Rau cov voj voog ib ceg (teeb pom kev zoo, cov khoom siv me me):Xaiv 1P;
2. Rau cov voj voog ib theem tseem ceeb lossis cov voj voog tseem ceeb:Xaiv 2P;
3. Rau cov khoom siv hauv kev lag luam peb-theem peb-xaim (tsis muaj xaim nruab nrab):Xaiv 3P;
4. Rau peb-theem plaub-xaim system nrog cov xaim hluav taws xob nruab nrab (cov tsev lag luam, cov chaw khaws ntaub ntawv):Xaiv 4P.
Kev xaiv tus lej ncej ntawm lub tshuab hluav taws xob yog thawj kab tiv thaiv rau kev nyab xeeb hluav taws xob. Yog tias koj tseem tsis paub meej txog kev xaiv tus lej ncej rau koj qhov project tshwj xeeb, thov koj ua siab dawb los saibtiv tauj peb cov kws pab tswv yim txog kev tshaj lij kom tau txais cov lus qhia tshaj lij thiab cov kev daws teeb meem tshwj xeeb.
