RCD yog dab tsi?

Cov cuab yeej hluav taws xob no tau tsim tshwj xeeb los hloov qhov ntws ntawm cov hluav taws xob tam sim no thaum twg cov av xau tau pom nyob rau theem tseem ceeb uas tuaj yeem tsim kev phom sij rau tib neeg.RCDs muaj peev xwm hloov cov dej ntws tam sim no hauv 10 mus rau 50 milliseconds ntawm kev kuaj pom qhov xau tom ntej.

Txhua RCD yuav ua haujlwm los saib xyuas cov hluav taws xob tam sim no los ntawm ib lossis ntau lub voj voog.Nws nquag tsom mus rau kev ntsuas cov kab nyob thiab nruab nrab.Thaum nws pom tias cov hluav taws xob tam sim no ntws los ntawm ob lub xov hlau tsis zoo ib yam, RCD yuav kaw lub voj voog.Qhov no qhia tau hais tias cov hluav taws xob tam sim no muaj txoj hauv kev uas tsis xav tau uas yuav ua rau muaj kev phom sij, xws li tus neeg kov cov xaim nyob lossis cov khoom siv uas ua yuam kev.

Hauv ntau qhov chaw nyob, cov cuab yeej tiv thaiv no yog siv hauv chav ntub dej thiab rau txhua yam khoom siv kom cov tswv tsev muaj kev nyab xeeb.Lawv kuj zoo tagnrho rau khaws cov khoom lag luam thiab kev lag luam kom zoo los ntawm hluav taws xob ntau dhau uas tuaj yeem ua rau puas tsuaj lossis txawm tias pib hluav taws xob tsis xav tau.

Koj Yuav Ntsuas RCDs li cas?

Kev ncaj ncees ntawm RCD yuav tsum tau sim ua ntu zus.Txhua lub qhov (socket) thiab ruaj RCD yuav tsum tau kuaj txhua txhua peb lub hlis.Portable units yuav tsum tau sim txhua zaus koj siv lawv.Kev ntsuam xyuas pab kom paub tseeb tias koj cov RCDs ua haujlwm tau zoo thiab yuav tiv thaiv koj los ntawm kev phom sij hluav taws xob.

Cov txheej txheem ntawm kev sim RCD yog ncaj ncaj.Koj xav ntaus lub pob xeem nyob rau pem hauv ntej ntawm lub cuab yeej.Thaum koj tso nws, lub pob yuav tsum disconnect lub zog tam sim no ntawm lub Circuit Court.

Kev tsoo lub pob tsuas ua rau lub ntiaj teb to qhov txhaum.Txhawm rau tig lub voj voog rov qab, koj yuav tsum tau qhib / tawm hloov rov qab mus rau qhov chaw nyob.Yog tias lub Circuit Court tsis kaw, ces muaj teeb meem nrog koj RCD.Nws yog qhov zoo tshaj plaws los sab laj ib tus kws kho hluav taws xob uas muaj ntawv tso cai ua ntej siv lub voj voog lossis cov khoom siv dua.

Yuav ua li cas txuas RCD - INSTALLATION DIAGRAM?

Kev sib txuas ntawm cov khoom seem-tam sim no kuj yooj yim, tab sis ob peb txoj cai yuav tsum ua raws.Ib qho RCD yuav tsum tsis txhob siv los ua ib qho ntawm cov khoom siv hluav taws xob thiab cov khoom thauj.Nws tsis tiv thaiv luv luv lossis overheating ntawm cov xov hlau.Rau kev nyab xeeb ntau dua, kev sib xyaw ntawm RCD thiab overcurrent Circuit Court breaker, tsawg kawg yog ib qho rau txhua RCD, raug pom zoo.

Txuas cov theem (xim av) thiab nruab nrab (xiav) xov hlau mus rau RCD input nyob rau hauv ib lub voj voog ib-theem.Tus neeg xyuas pib tiv thaiv yog txuas nrog xws li lub davhlau ya nyob twg strip.

Cov theem xaim ntawm RCD cov zis yuav tsum tau txuas nrog lub overcurrent Circuit Court breaker, thaum cov hlau nruab nrab tuaj yeem txuas ncaj qha rau lub installation.
