Hauv cov chaw tsim khoom lag luam, kev tiv thaiv kev nyab xeeb ntawm kev saib xyuas cov khoom siv hluav taws xob thiab kev saib xyuas lub kaw lus faib hluav taws xob yog cov ntsiab lus tseem ceeb ntawm kev tsim khoom lag luam kev nyab xeeb. LubLOTO (Xauv/Tagout)Lub kaw lus, uas cuam tshuam nrog kev xauv thiab cim npe los thaiv lub zog hluav taws xob txaus ntshai thiab tiv thaiv kev ua haujlwm tsis raug ntawm cov circuit breakers, yog "kab kev tiv thaiv tseem ceeb" rau kev tiv thaiv kev nyab xeeb ntawm cov neeg ua haujlwm thiab tiv thaiv kev puas tsuaj hluav taws xob. Raws li cov ntaub ntawv, ntau dua ib nrab ntawm kev sib tsoo hluav taws xob yog cuam tshuam nrog qhov tsis muaj lossis kev siv tsis raug ntawm LOTO txheej txheem. Ntawm lawv, kev sib tsoo los ntawm kev ua haujlwm tsis raug ntawm cov circuit breakers, xws li hluav taws xob poob siab, cov khoom siv luv luv, thiab txawm tias hluav taws, suav rau feem ntau. Lub circuit breaker xauv, ua lub cuab yeej xauv tseem ceeb rau kev cais cov khoom siv hluav taws xob hauv cov txheej txheem LOTO, yog cuam tshuam ncaj qha rau kev xaiv tus qauv thiab kev siv raug ntawm ntau hom circuit breakers thiab yog cov ntsiab lus tseem ceeb uas cov kws tshaj lij kev nyab xeeb hauv kev lag luam thiab cov neeg ua haujlwm hluav taws xob yuav tsum paub txog. Tsab xov xwm no yuav muab kev tshuaj xyuas ntxaws ntxaws thiab kev qhia txog ntau hom circuit breakers los ntawm qhov pom ntawm LOTO, nrog rau cov phiaj xwm xauv, thiab teb cov lus nug hauv kev lag luam los pab cov tuam txhab ua kom tus qauv siv ntawm LOTO system thiab txhawb nqa kab kev tiv thaiv kev nyab xeeb hluav taws xob hauv kev lag luam.
Hauv qab no, kuv yuav tshuaj xyuas, qhia, thiab muab cov phiaj xwm xauv rau ntau hom circuit breakers los ntawm kev xav ntawm LOTO.
I. Cov Hluav Taws Xob Me Me
Cov cuab yeej hluav taws xob me me yog cov khoom siv hluav taws xob tiv thaiv yooj yim tshaj plaws hauv cov tshuab faib hluav taws xob hauv kev lag luam. Lawv feem ntau yog siv rau kev tiv thaiv overload thiab luv luv, muaj qhov me me, muaj peev xwm tawg nruab nrab, thiab kev ua haujlwm yooj yim. Lawv yog cov khoom tseem ceeb ntawm kev faib hluav taws xob hauv cov chaw ua haujlwm hauv kev lag luam, cov thawv faib khoom, thiab cov khoom siv me me. Hauv LOTO kev ua haujlwm, cov cuab yeej hluav taws xob me me ua lub node tseem ceeb rau kev cais lub zog hluav taws xob ntawm qhov kawg pem hauv ntej. Yog tias tsis xauv raws li cov cai, lawv tuaj yeem ua rau cov khoom siv kho vaj tse hauv qab tam sim ntawd muaj zog vim tias cov neeg ua haujlwm kaw lub cuab yeej hluav taws xob tsis raug, ua rau muaj xwm txheej xws li hluav taws xob poob siab, khoom siv puas tsuaj, thiab lwm yam. Yog li ntawd, yuav tsum tau xauv lub cev los ntawm kev xauv tshwj xeeb kom ua raws li cov kev cai cais lub zog LOTO.
Cov hom lag luam ntawm cov hluav taws xob me me:
⑴. Hauv tebchaws: CHINT, DELIXI, PEOPLE, TENGEN, Nader, thiab lwm yam. ⑵. Txawv tebchaws: Schneider Electric, ABB, Siemens, Eaton, Legrand, thiab lwm yam.
a. Cov xwm txheej ntawm daim ntawv thov:
5. Kev tiv thaiv kab thiab kev cais hluav taws xob hauv cov thawv faib khoom me me thiab cov thawv tswj khoom siv hauv cov chaw ua haujlwm hauv kev lag luam;
⑵. Kev saib xyuas cov tshuab faib hluav taws xob qis hauv cov chaw ua haujlwm thiab cov chaw pabcuam kev lag luam;
⑶. Kev saib xyuas cov ceg me me thiab cov hluav taws xob rau cov cuab yeej siv precision hauv cov kab ntau lawm tsis siv neeg.
II. Moulded Case Circuit Breaker
Lub tshuab hluav taws xob molded case muaj cov haujlwm ntawm kev tiv thaiv overload, luv luv, thiab tsis muaj zog. Nws muaj peev xwm tawg tau zoo thiab muaj ntau yam tam sim no. Lub thawv yog ua los ntawm cov khoom siv yas rwb thaiv tsev, uas tuaj yeem tiv thaiv kev raug hluav taws xob arc. Nws yog lub hauv paus tseem ceeb ntawm lub kaw lus faib hluav taws xob hauv kev lag luam thiab siv dav rau kev tiv thaiv thiab tswj cov khoom siv hluav taws xob siab, kev faib hluav taws xob tseem ceeb hauv chaw ua haujlwm, thiab cov kab hluav taws xob faib hluav taws xob.
Ua ib qho chaw tseem ceeb rau kev cais hluav taws xob hauv cov chaw lag luam, lub tshuab hluav taws xob molded case txuas lub zog ntawm cov khoom siv hluav taws xob siab. Kev ua haujlwm tsis raug ntawm kev kaw lub qhov hloov pauv yuav ua rau muaj hluav taws xob ntau heev, ua rau raug mob hnyav thiab cov khoom siv puas tsuaj. Yog li ntawd, thaum lub sijhawm LOTO ua haujlwm, nws yog qhov tsim nyog los ua kom tiav lub xauv ruaj ntseg los ntawm kev siv lub xauv hnyav thiab ua ke ntau yam kev tiv thaiv kom ntseeg tau tias muaj kev cais hluav taws xob zoo.
III. Lub Tshuab Hluav Taws Xob Rau Hauv Ncej
Ib lub frame circuit breaker, tseem hu ua universal circuit breaker, muaj cov hluav taws xob loj, muaj peev xwm cuam tshuam tau zoo heev, thiab muaj kev tiv thaiv zoo. Nws siv tau hluav taws xob thiab tes ua haujlwm, thiab feem ntau yog siv ua lub qhov hloov tseem ceeb hauv lub tshuab faib hluav taws xob ntawm cov tuam txhab lag luam. Nws yog lub hauv paus tswj thiab tiv thaiv ntawm tag nrho lub network faib hluav taws xob hauv kev lag luam. Lub frame circuit breaker tswj lub zog hluav taws xob ntawm tag nrho lub chaw ua haujlwm lossis thaj chaw Hoobkas. Kev ua haujlwm LOTO (Lockout-Tagout) ntawm LOTO vaj huam sib luag yog qhov tseem ceeb tshaj plaws rau kev nyab xeeb hluav taws xob hauv kev lag luam. Yog tias nws ua haujlwm tsis raug, nws yuav ua rau muaj kev puas tsuaj loj, ua rau cov khoom siv puas tsuaj, lossis txawm tias muaj kev phom sij loj rau kev nyab xeeb ntawm tus kheej. Yog li ntawd, nws yog qhov tsim nyog ua raws li tag nrho cov txheej txheem ntawm LOTO thiab siv cov xauv muaj zog siab kom ua tiav ntau qhov kev cais tawm lub cev, thiab siv lub hauv paus ntsiab lus ntawm "leej twg xauv, leej twg qhib".
a. Cov xwm txheej ntawm daim ntawv thov
5. Lub qhov hloov tseem ceeb rau kev cais hluav taws xob hauv chav faib khoom tseem ceeb ntawm cov chaw tsim khoom lag luam thiab cov chaw ua lag luam loj;
⑵. Kev saib xyuas lub tshuab faib hluav taws xob hauv cov lag luam loj xws li metallurgy, fais fab, thiab tshuaj lom neeg;
⑶. Cov qhov hloov tswj kev faib khoom tseem ceeb rau cov kab ntau lawm loj thiab cov chaw tsim khoom ntse rau LOTO kev ua haujlwm.
