To taub lub switchboard: ib qho tseem ceeb hauv lub tshuab hluav taws xob
Hauv cov tshuab hluav taws xob, cov switchboards ua lub luag haujlwm tseem ceeb hauv kev ua kom lub zog tau faib tawm kom muaj kev nyab xeeb thiab ua haujlwm tau zoo thoob plaws hauv lub tsev lossis chaw. Feem ntau hu ua switchboards, panels, lossis switchboards, switchboards yog lub hauv paus tseem ceeb rau kev tswj hwm thiab tiv thaiv cov hluav taws xob circuits. Hauv tsab xov xwm no, peb yuav tshawb nrhiav qhov tseem ceeb ntawm switchboards, lawv cov khoom, thiab lawv cov ntawv thov hauv ntau qhov chaw.
Dab tsi yog ib qholub thawv faib khoom?
Lub thawv faib khoom yog ib lub thawv uas muaj cov khoom siv hluav taws xob, suav nrog cov khoom siv hluav taws xob, cov fuses, thiab cov xov hlau. Nws lub luag haujlwm tseem ceeb yog faib hluav taws xob los ntawm ib qho chaw mus rau ntau lub voj voog thiab muab kev tiv thaiv overload thiab luv luv. Los ntawm kev tswj hwm lub voj voog hauv nruab nrab, cov thawv faib khoom tuaj yeem txhim kho kev nyab xeeb thiab yooj yim rau kev saib xyuas.
Cov Cheebtsam ntawm lub thawv faib khoom
1. Lub Tshuab Hluav Taws Xob Tua Hluav Taws Xob (Circuit Breaker): Qhov no yog lub qhov hloov pauv tsis siv neeg uas siv los 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 tshuab hluav taws xob tua hluav taws xob yuav txiav tawm, txiav lub zog thiab tiv thaiv kev puas tsuaj uas yuav tshwm sim.
2. Fuse: Lub fuse zoo ib yam li lub circuit breaker uas nws tiv thaiv lub circuit los ntawm kev yaj cov hlau thaum tam sim no tshaj qhov nqi nyab xeeb. Lub fuse yuav tsum tau hloov tom qab nws tawg, thaum lub circuit breaker tuaj yeem rov pib dua, uas yog qhov kev xaiv yooj yim dua hauv ntau kis.
3. Cov Busbars: Cov hlau conductive no yog siv los faib cov hluav taws xob mus rau ntau lub voj voog hauv lub thawv faib khoom. Lawv feem ntau yog ua los ntawm tooj liab lossis txhuas thiab tau tsim los tswj cov khoom siv hluav taws xob siab.
4. Cov Chaw Txuas thiab Cov Khoom Txuas: Cov khoom no pab txuas cov xov hlau nkag thiab tawm, kom ntseeg tau tias muaj kev sib txuas hluav taws xob zoo thiab txhim khu kev qha.
5. Lub thawv kaw: Lub thawv faib khoom raug kaw rau 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 thiab kev sib tsoo tsis tau xav txog.
Daim ntawv thov ntawm lub thawv faib khoom
Cov thawv faib hluav taws xob siv rau ntau yam kev siv, txij li cov tsev nyob mus rau cov chaw lag luam loj. Nov yog qee qhov kev siv dav dav:
- Ib puag ncig nyob: Hauv ib puag ncig nyob, cov thawv faib khoom feem ntau nyob hauv qab nthab lossis chav siv hluav taws xob. Lawv tswj hwm lub zog rau txhua chav thiab cov khoom siv, kom ntseeg tau tias txhua lub voj voog tau txais lub zog tsim nyog.
- Cov Tsev Lag Luam: Hauv cov chaw lag luam, cov thawv faib khoom yog qhov tseem ceeb rau kev tswj hwm cov kev xav tau hluav taws xob ntawm ntau tus neeg xauj tsev lossis chav haujlwm. Lawv pab ua kom txhua thaj chaw muaj kev muab hluav taws xob txhim khu kev qha thaum tswj hwm cov qauv kev nyab xeeb.
- Cov Chaw Lag Luam: Hauv cov chaw tsim khoom thiab cov chaw tsim khoom, cov thawv faib khoom yog qhov tseem ceeb rau kev tswj hwm cov tshuab hnyav thiab cov khoom siv. Lawv tau tsim los tswj cov khoom siv hluav taws xob siab thiab cov khoom siv tam sim no siab, muab kev tiv thaiv zoo tiv thaiv kev ua txhaum hluav taws xob.
- Kev Teeb Sab Nraum Zoov: Cov thawv faib khoom kuj siv rau hauv cov ntawv thov sab nraum zoov xws li teeb pom kev zoo ntawm txoj kev thiab kev sib txuas lus. Cov thawv faib khoom no feem ntau tiv taus huab cua thiab tuaj yeem tiv taus ntau yam xwm txheej ib puag ncig.
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 raug thiab kev saib xyuas tsis tu ncua. Ib txwm xyuas kom tseeb tias nws 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 nrhiav pom cov teeb meem uas yuav tshwm sim, xws li kev sib txuas xoob lossis cov cim ntawm kev hnav, yog li tiv thaiv kev phom sij hluav taws xob.
Tag nrho hauv txhua yam, lub switchboard yog ib qho tseem ceeb ntawm txhua lub tshuab hluav taws xob, muab txoj hauv kev nyab xeeb thiab ua haujlwm tau zoo los faib hluav taws xob. Kev nkag siab txog nws cov khoom thiab cov ntawv thov tuaj yeem pab cov tswv tsev, cov tswv lag luam, thiab cov thawj coj hauv chaw lees paub nws qhov tseem ceeb hauv kev tswj hwm lub zog hluav taws xob txhim khu kev qha. Los ntawm kev muab qhov tseem ceeb rau kev teeb tsa thiab kev saib xyuas kom zoo, peb tuaj yeem ua kom ntseeg tau tias lub tshuab hluav taws xob yuav ua haujlwm tau zoo thiab muaj txiaj ntsig rau ntau xyoo tom ntej.
