Txawv ntawm qhov tsos thiab cov qauv, cov txee tswj hluav taws xob thiabcov txee faib khoom(cov switchboards) yog tib hom, thiab cov thawv tswj hluav taws xob thiab cov thawv faib khoom yog tib hom.
Lub thawv tswj hluav taws xob thiab lub thawv faib hluav taws xob tau kaw rau rau sab thiab feem ntau yog ntsia rau ntawm phab ntsa. Muaj cov qhov khob tawm rau sab saum toj thiab hauv qab ntawm lub thawv kom yooj yim nkag thiab tawm ntawm cov xov hlau thiab cov cables mus rau hauv lub thawv tswj hluav taws xob thiab faib hluav taws xob.
Cov txee tswj hluav taws xob thiab cov txee faib khoom raug kaw rau tsib sab thiab tsis muaj hauv qab. Feem ntau lawv raug teeb tsa rau hauv pem teb tiv thaiv phab ntsa.
Feem ntau lub switchboard raug kaw rau ob sab, thiab kuj muaj peb, plaub thiab tsib sab. Lub switchboard raug ntsia rau hauv pem teb, tab sis sab nraub qaum tsis tuaj yeem tiv thaiv phab ntsa. Yuav tsum muaj chaw rau kev ua haujlwm thiab kev saib xyuas tom qab lub switchboard.
Cov sab tshwj xeeb ntawm lub switchboard raug kaw, thiab koj yuav tsum tau ua ib qho kev thov thaum xaj khoom. Piv txwv li, yog tias tsib lub switchboards raug teeb tsa ua ke thiab txuas ntxiv mus, tsuas yog sab laug ntawm thawj qhov xav tau lub baffle, sab xis ntawm qhov thib tsib xav tau lub baffle, thiab sab laug thiab sab xis ntawm qhov thib ob, thib peb, thiab thib plaub txhua tus qhib.
Yog tias muaj ib lub qhov hluav taws xob uas raug teeb tsa thiab siv ywj pheej, yuav tsum muaj cov baffles rau sab laug thiab sab xis. Feem ntau, sab nraub qaum ntawm lub switchboard qhib. Kuj tseem muaj lub qhov rooj nyob tom qab raws li tus neeg siv xav tau, uas tuaj yeem tiv thaiv cov hmoov av thiab pab txhawb kev ua haujlwm thiab kev saib xyuas.
Los ntawm kev xav txog kev ua haujlwm, cov vaj huam sib luag faib khoom,cov txee faib khoomthiab cov thawv faib khoom yog cov uas koom nrog tib pawg, thiab cov thawv tswj hluav taws xob thiab cov txee tswj hluav taws xob yog cov uas koom nrog tib pawg.
Feem ntau hais lus, cov laug cam faib hluav taws xob faib cov zog hluav taws xob mus rau cov txee faib hluav taws xob qis dua thiab cov thawv faib hluav taws xob, lossis faib hluav taws xob ncaj qha mus rau cov khoom siv hluav taws xob. Cov txee faib hluav taws xob thiab cov thawv faib hluav taws xob ncaj qha mus rau cov khoom siv hluav taws xob. Qee zaum cov txee faib hluav taws xob kuj siv tau. Nws faib hluav taws xob mus rau cov thawv faib hluav taws xob qis dua.
Cov thawv tswj hluav taws xob thiabcov txee tswj hluav taws xobfeem ntau yog siv los tswj cov khoom siv hluav taws xob, thiab tseem muaj lub luag haujlwm ntawm kev faib hluav taws xob rau cov khoom siv hluav taws xob.
Cov riam hloov, riam-fusion hloov, cua hloov, fuses, magnetic starters (contactors) thiab thermal relays feem ntau yog ntsia rau hauv cov txee faib khoom, cov thawv faib khoom thiab cov laug cam faib khoom. Qee zaum cov transformers tam sim no, voltage transformers, ammeters, voltmeters, watt-hour meters, thiab lwm yam kuj raug ntsia.
Ntxiv rau cov khoom siv hluav taws xob uas tau hais los saum toj no, cov thawv tswj hluav taws xob thiabcov txeekuj tseem yuav nruab nrog cov relays nruab nrab, lub sijhawm relays, cov nyees khawm tswj, teeb qhia, hloov pauv hloov pauv thiab lwm yam kev ua haujlwm hloov pauv thiab cov khoom siv tswj. Qee qhov txawm tias suav nrog cov hloov pauv zaus, PLC, ib lub microcomputer, I / O hloov pauv khoom siv, AC / DC transformer regulator, thiab lwm yam tau teeb tsa hauv lub thawv tswj hluav taws xob thiab lub txee tswj hluav taws xob. Hauv qee kis, qhov kub, siab, thiab cov cuab yeej tso saib ntws kuj tau teeb tsa hauv lub thawv tswj hluav taws xob thiab lub txee tswj hluav taws xob. saum toj no.
Peb tau kawm txog kev faib tawm ua ntej lawm, cia peb saib ze dua nws cov qauv:
Lublub txee tswj hluav taws xobyog ib feem tseem ceeb ntawm cov tshuab tshem plua plav. Lub txee tswj hluav taws xob ua tus thawj coj hauv kev txhim kho kev lag luam nrog nws cov khoom siv tes ua zoo heev thiab cov thev naus laus zis ua thawj coj. Cia peb saib qee cov qauv yooj yim ntawm lub txee tswj hluav taws xob.
Lub txee tswj hluav taws xob siv PLC programmable module ua lub khoos phis tawj tswj hwm kom paub txog kev ntxuav tshauv tsis siv neeg, tshem tawm tshauv, tso saib qhov kub thiab txias, hloov pauv hla thiab lwm yam kev tswj hwm, ua tau raws li qhov yuav tsum tau ua ntawm tus neeg yuav khoom.
Lub txee tswj hluav taws xob muaj kev ntseeg siab heev. Nws siv cov khoos phis tawj IPC niaj hnub no, cov chassis lag luam embedded, LCD monitors, thiab cov vaj huam sib luag hluav taws xob kom ntseeg tau tias tus tswv tsev muaj kev ntseeg siab. Lub txee tswj hluav taws xob siv cov khoom siv hluav taws xob muaj kev ntseeg siab, cov nyees khawm xa tuaj, thiab cov hloov pauv. , relay tsis sib cuag, kom ntseeg tau tias muaj kev ntseeg siab hluav taws xob.
Lublub txee tswj hluav taws xobsiv lub tshuab ua haujlwm DOS, uas muaj kev ntseeg siab thiab kev ua haujlwm tiag tiag, uas ua rau muaj kev ntseeg siab ntawm cov software ntau ntxiv; lub txee tswj hluav taws xob siv cov sensors txoj haujlwm tsis sib cuag, cov cuab yeej siv thev naus laus zis siab, thiab cov sensors fais fab ua haujlwm siab kom ntseeg tau tias muaj kev ntseeg siab ntawm cov sensors; Qhov kev teeb tsa tsim nyog thiab kev tsim qauv siab ntawm lub txee tswj hluav taws xob txo qis kev sib txuas ntawm lub kaw lus thiab txo cov kab tsis ua haujlwm. Lub txee tswj hluav taws xob muaj peev xwm tiv thaiv kev cuam tshuam zoo. Nws siv cov thev naus laus zis photoelectric cais tag nrho thiab cov thev naus laus zis tiv thaiv kev cuam tshuam software los txhim kho lub peev xwm tiv thaiv kev cuam tshuam ntawm lub kaw lus.
Lub txee tswj hluav taws xob siv cov software thiab kho vajtse lim dej thev naus laus zis los txhim kho lub peev xwm tiv thaiv kev cuam tshuam thiab qhov tseeb ntawm lub sensor. Qhov kev teeb tsa tsim nyog ntawm lub txee tswj hluav taws xob tuaj yeem daws qhov kev sib tshuam ntawm cov hluav taws xob muaj zog thiab tsis muaj zog.
