To taub lub switchboard: ib qho tseem ceeb hauv lub tshuab hluav taws xob
Hauv ntiaj teb ntawm cov tshuab hluav taws xob, cov switchboards ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm kev faib hluav taws xob thoob plaws hauv lub tsev lossis chaw. Cov khoom tseem ceeb no, feem ntau hu ua switchboard, vaj huam sib luag, lossis switchboard, yog lub hauv paus tseem ceeb rau kev tswj hwm thiab tiv thaiv cov hluav taws xob. Hauv tsab xov xwm no, peb yuav tshawb nrhiav qhov tseem ceeb ntawm cov switchboards, lawv cov khoom, thiab lawv cov ntawv thov hauv ntau qhov chaw.
Dab tsi yog ib qholub thawv faib khoom?
Lub switchboard yog ib lub thawv uas muaj cov khoom siv hluav taws xob, suav nrog cov circuit breakers, fuses, thiab wiring. Nws lub luag haujlwm tseem ceeb yog faib hluav taws xob los ntawm ib qho chaw mus rau ntau lub circuits thaum muab kev tiv thaiv overload thiab luv luv. Los ntawm kev tswj hwm circuit, switchboards tuaj yeem txhim kho kev nyab xeeb thiab yooj yim txij nkawm.
Cov Cheebtsam ntawm lub thawv faib khoom
1. Cov Circuit Breakers: Cov no yog cov qhov hloov pauv tsis siv neeg uas tiv thaiv cov hluav taws xob ntawm kev thauj khoom ntau dhau thiab luv luv. Thaum cov hluav taws xob ntau tshaj qhov txwv uas tau teem tseg, lub circuit breaker yuav txiav tawm, txiav lub zog thiab tiv thaiv kev puas tsuaj rau lub cev hluav taws xob.
2. Fuse: Cov fuses zoo ib yam li cov circuit breakers uas lawv tiv thaiv tau overcurrent. Txawm li cas los xij, tsis zoo li cov circuit breakers, cov fuses yuav tsum tau hloov thaum lawv hlawv tawm. Cov fuses muaj cov hlau hlau uas yaj thaum cov tam sim no tshaj qhov qib kev nyab xeeb, yog li txiav cov dej ntws ntawm tam sim no.
3. Cov Hlau Npav: Cov no yog cov hlau uas xa hluav taws xob mus rau cov voj voog hauv lub thawv faib hluav taws xob. Lawv tau tsim los tswj cov hluav taws xob siab thiab feem ntau yog ua los ntawm tooj liab lossis txhuas.
4. Cov Qws thiab Cov Khoom Txuas: Cov khoom no pab txuas cov xov hlau nkag thiab tawm. Cov qws uas ruaj khov zoo ua kom muaj kev sib txuas hluav taws xob zoo, txo qhov kev pheej hmoo ntawm kev kub hnyiab thiab kub dhau.
5. Lub thawv kaw: Lub thawv faib khoom nyob hauv lub thawv tiv thaiv, uas tuaj yeem ua los ntawm hlau lossis yas. Lub thawv kaw tiv thaiv cov khoom sab hauv los ntawm cov yam ntxwv ib puag ncig xws li hmoov av, dej noo, thiab kev puas tsuaj rau lub cev.
Daim ntawv thov ntawm lub thawv faib khoom
Cov thawv faib khoom siv rau ntau qhov chaw suav nrog kev nyob hauv tsev, kev lag luam, thiab kev lag luam.
- Siv rau hauv tsev: Hauv tsev, lub thawv faib hluav taws xob feem ntau nyob hauv chav siv hluav taws xob lossis hauv qab nthab. Nws faib hluav taws xob mus rau ntau qhov chaw ntawm lub tsev, xws li teeb pom kev zoo, qhov hluav taws xob tawm, thiab cov khoom siv hluav taws xob. Cov tswv tsev kuj tseem tuaj yeem teeb tsa cov hluav taws xob ntxiv rau cov hluav taws xob tshiab raws li qhov xav tau.
- Kev Siv Lag Luam: Hauv cov tsev lag luam, cov thawv faib khoom tswj hwm kev muab hluav taws xob rau ntau tus neeg xauj tsev lossis chav haujlwm. Lawv ua kom txhua thaj chaw tau txais hluav taws xob txaus thaum tswj hwm cov qauv kev nyab xeeb. Tsis tas li ntawd, cov thawv faib khoom lag luam yuav muaj cov yam ntxwv los saib xyuas kev siv hluav taws xob.
- Kev Siv Hauv Kev Lag Luam: Hauv cov chaw ua lag luam, cov thawv faib khoom yog qhov tseem ceeb rau kev tswj hwm cov tshuab hluav taws xob muaj zog siab. Lawv feem ntau muaj cov yam ntxwv kev nyab xeeb siab heev thiab cov txheej txheem saib xyuas kom tau raws li qhov xav tau ntawm cov tshuab hnyav thiab cov khoom siv.
Qhov Tseem Ceeb ntawm Kev Teeb tsa thiab Kev Saib Xyuas Kom Zoo
Qhov ua tau zoo ntawm lub thawv hloov pauv feem ntau nyob ntawm nws qhov kev teeb tsa kom zoo thiab kev saib xyuas tsis tu ncua. Ib txwm xyuas kom tseeb tias lub thawv hloov pauv tau teeb tsa los ntawm tus kws hluav taws xob uas tsim nyog uas ua raws li cov cai hluav taws xob hauv zos thiab cov qauv. Kev tshuaj xyuas tsis tu ncua tuaj yeem pab txheeb xyuas cov teeb meem uas yuav tshwm sim, xws li kev sib txuas xoob lossis cov khoom siv hnav, ua ntej lawv ua rau muaj teeb meem loj dua.
Hauv kev xaus lus, cov switchboards yog ib feem tseem ceeb ntawm txhua lub tshuab hluav taws xob, muab kev faib hluav taws xob kom muaj kev nyab xeeb, kev txiav txim siab thiab kev siv tau zoo. Kev nkag siab txog cov khoom thiab kev siv ntawm cov switchboards tuaj yeem pab cov tib neeg thiab cov lag luam txiav txim siab txog lawv cov kev xav tau hluav taws xob. Txawm hais tias nyob hauv tsev, chaw ua haujlwm lossis chaw ua haujlwm, cov switchboards yog ib feem tseem ceeb ntawm kev tswj hwm hluav taws xob kom muaj kev nyab xeeb.
