Hauv cov chaw tsim khoom, kev tiv thaiv kev nyab xeeb ntawm cov khoom siv hluav taws xob tu thiab kev saib xyuas ntawm lub zog xa hluav taws xob yog qhov tseem ceeb ntawm kev tsim khoom lag luam kev nyab xeeb. CovLOTO (Lockout / Tagout)system, uas suav nrog kev kaw thiab tagging los thaiv cov hluav taws xob muaj kev phom sij thiab tiv thaiv kev ua haujlwm tsis zoo ntawm cov hluav taws xob hluav taws xob, yog "txoj kab tseem ceeb ntawm kev tiv thaiv" rau kev tiv thaiv tus kheej kev nyab xeeb ntawm cov neeg ua haujlwm thiab tiv thaiv hluav taws xob. Raws li cov ntaub ntawv, ntau tshaj li ib nrab ntawm cov khoom siv hluav taws xob kho hluav taws xob muaj feem cuam tshuam nrog kev tsis tuaj lossis kev siv tsis raug ntawm LOTO txheej txheem. Ntawm lawv, cov xwm txheej tshwm sim los ntawm kev ua haujlwm tsis zoo ntawm cov hluav taws xob hluav taws xob, xws li hluav taws xob poob siab, cov khoom siv hluav taws xob luv luv, thiab txawm tias hluav taws kub hnyiab, suav nrog cov feem ntau. Lub ntsuas hluav taws xob ntsuas hluav taws xob, raws li cov khoom siv tseem ceeb rau kev cais cov hluav taws xob hluav taws xob hauv cov txheej txheem LOTO, yog ncaj qha ntsig txog cov txheej txheem xaiv thiab siv tau zoo ntawm ntau hom hluav taws xob hluav taws xob thiab yog cov ntsiab lus tseem ceeb uas cov kws tshaj lij kev nyab xeeb thiab cov neeg ua haujlwm hluav taws xob yuav tsum paub txog. Tsab ntawv xov xwm no yuav muab cov ncauj lus kom ntxaws ntxaws thiab qhia txog ntau hom kev sib txuas ntawm Circuit Court breakers los ntawm kev xaav ntawm LOTO, nrog rau cov txheej txheem kaw, thiab teb cov lus nug hauv kev lag luam los pab cov tuam txhab tsim qauv kev siv LOTO thiab ntxiv dag zog rau kev lag luam hluav taws xob tiv thaiv kab.
Hauv qab no, kuv yuav txheeb xyuas, qhia, thiab muab cov phiaj xwm xauv rau ntau hom kev sib txuas ntawm cov khoom siv hluav taws xob los ntawm LOTO txoj kev xav.
I. Me me Circuit Court Breakers
Cov kab hluav taws xob me me yog cov khoom siv hluav taws xob tiv thaiv yooj yim tshaj plaws hauv kev lag luam hluav taws xob faib hluav taws xob. Lawv feem ntau yog siv rau overload thiab luv luv - tiv thaiv Circuit Court, featuring me me, nruab nrab tawg peev xwm, thiab kev ua haujlwm yooj yim. Lawv yog cov khoom siv hluav taws xob tseem ceeb hauv cov chaw ua haujlwm hauv kev lag luam, cov thawv xa khoom, thiab cov khoom siv me me. Hauv kev ua haujlwm LOTO, cov khoom siv hluav taws xob me me ua lub luag haujlwm tseem ceeb rau kev cais hluav taws xob hluav taws xob nyob rau pem hauv ntej kawg. Yog tias tsis raug kaw raws li cov cai, lawv tuaj yeem yooj yim ua rau cov khoom siv hauv qab dej tau yooj yim ua rau muaj zog vim tias cov neeg ua haujlwm yuam kev kaw lub Circuit Court breaker, ua rau muaj kev sib tsoo xws li hluav taws xob poob siab, khoom siv puas tsuaj, thiab lwm yam. Yog li ntawd, kev kaw lub cev yuav tsum tau ua tiav los ntawm kev ntsuas tshwj xeeb los ua raws li LOTO lub zog cais tawm.
Hom hom ntawm me me Circuit Court breakers:
⑴. Hauv tsev: CHINT, DELIXI, PEOPLE, TENGEN, Nader, thiab lwm yam. ⑵. Txawv teb chaws: Schneider Electric, ABB, Siemens, Eaton, Legrand, thiab lwm yam.
a. Daim ntawv thov scenarios:
⑴. Kev tiv thaiv kab thiab kev sib cais hluav taws xob hauv cov thawv me me thiab cov khoom siv tswj lub thawv hauv kev cob qhia kev lag luam;
⑵. Kev saib xyuas ntawm qis-voltage fais fab faib tshuab hauv chaw ua haujlwm thiab chaw ua haujlwm pabcuam;
⑶. Kev saib xyuas ntawm cov ceg me me thiab cov khoom siv hluav taws xob rau cov cuab yeej precision hauv cov kab ntau lawm.
II. Moulded Case Circuit Breaker
Lub molded case Circuit breaker muaj lub luag haujlwm ntawm overload, luv Circuit Court, thiab nyob rau hauv -voltage tiv thaiv. Nws muaj zog tawg muaj peev xwm thiab ib tug dav rated tam sim no ntau yam. Lub kaw lus yog ua los ntawm cov khoom siv yas insulating, uas tuaj yeem tiv thaiv kev cuam tshuam ntawm arc. Nws yog lub hauv paus tseem ceeb ntawm cov hluav taws xob faib hluav taws xob hauv kev lag luam thiab tau siv dav rau kev tiv thaiv thiab tswj cov khoom siv hluav taws xob siab -, rhiav lub ntsiab hluav taws xob faib hluav taws xob, thiab cov kab hluav taws xob faib hluav taws xob.
Raws li ib qho tseem ceeb ntawm hluav taws xob hluav taws xob cais qhov chaw nyob rau hauv cov chaw tsim khoom, lub molded case Circuit Court breaker txuas lub zog ntawm high - khoom siv fais fab. Kev ua haujlwm tsis zoo ntawm kev kaw qhov hloov pauv yuav ua rau muaj kev tso tawm hluav taws xob loj, ua rau tus kheej raug mob hnyav thiab khoom siv puas tsuaj. Yog li ntawd, thaum lub sijhawm ua haujlwm LOTO, nws yog ib qho tsim nyog yuav tsum ua kom muaj kev ruaj ntseg xauv los ntawm kev mob siab rau hnyav - lub luag haujlwm xauv thiab sib txuas ntau yam kev tiv thaiv kom ntseeg tau tias muaj zog sib cais.
III. Ncej Circuit Breaker
Lub thav duab Circuit Court breaker, tseem hu ua universal circuit breaker, nta ib tug loj rated tam sim no, muaj zog heev cuam tshuam lub peev xwm, thiab kev tiv thaiv kev ua haujlwm. Nws tuaj yeem ua haujlwm ob qho tib si hluav taws xob thiab manually thiab feem ntau yog siv los ua lub ntsiab hloov hauv lub zog faib hluav taws xob ntawm cov tuam txhab lag luam. Nws yog qhov tseem ceeb ntawm kev tswj hwm thiab kev tiv thaiv ntawm tag nrho cov khoom siv hluav taws xob faib hluav taws xob. Lub thav duab Circuit Court breaker tswj cov hluav taws xob lub zog ntawm tag nrho cov rhiav lossis lub Hoobkas cheeb tsam. LOTO (Lockout-Tagout) kev ua haujlwm ntawm LOTO vaj huam sib luag yog qhov tseem ceeb tshaj plaws rau kev lag luam hluav taws xob kev nyab xeeb. Yog tias nws ua haujlwm tsis raug, nws yuav ua rau muaj hluav taws xob loj - hluav taws xob tawg, kev puas tsuaj rau pawg khoom siv, lossis txawm tias muaj xwm txheej loj ntawm tus kheej. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum ua raws li cov txheej txheem tag nrho ntawm LOTO thiab siv siab siab siab - lub zog ntsuas phoo kom ua tiav ntau qhov kev sib cais ntawm lub cev, thiab siv lub hauv paus ntsiab lus ntawm "leej twg xauv, leej twg qhib".
a. Daim ntawv thov scenarios
⑴. Kev hloov pauv tseem ceeb rau kev sib cais lub zog hauv chav faib khoom loj ntawm cov nroj tsuag thiab cov chaw ua haujlwm loj;
⑵. Fais fab kev faib system txij nkawm hauv kev lag luam loj xws li metallurgy, fais fab, thiab tshuaj lom neeg kev lag luam;
⑶. Main faib tswj keyboards rau loj automated ntau lawm kab thiab ntse factories rau LOTO ua hauj lwm.
