Indlela yokukhetha isixhobo sokukhiya i-circuit Breaker esifanelekileyo
Makhe ndikuxelele ngesiganeko esenzeka ngokuphindaphindiweyo kumzi-mveliso: Ngaphambi kokuba kwenziwe ulungiso lombane, umntu wayesusa iswitshi ye-circuit breaker kwikhabhathi yokuhambisa izinto aye kwindawo ethi “OFF”, axhome uphawu, ecinga ukuba oku kukhuselekile. Nangona kunjalo, iqela elikufutshane, lingazi ukuba kukho umntu olungisa izinto, labuya laza layivula kwakhona i-circuit breaker – izixhobo zaqala ngequbuliso, kwaye abasebenzi bokulungisa baphantse baba nengozi.
Injongo yeCircuit Breaker Lockout kukutshintsha imeko ukusuka ekubeni “kucingelwa ukuba icinyiwe” ukuya ekubeni “akukho mntu unokuyivula”. Nangona kunjalo, ingxaki kukuba ii-circuit breakers ziza ngeendidi ezahlukeneyo zeemilo nobukhulu, kwaye izixhobo zokutshixa nazo zahlulwe zaba ziintlobo ngeentlobo. Eli nqaku likunceda ucacise indlela ocinga ngayo ngaphambi kokuba uthenge, ukuze ungathengi into uze ufumanise ukuba ayinakufakwa kamva.
Okokuqala, qiniseka ukuba uyayiqonda i-circuit breaker.
Ngaphambi kokuba uthenge isitshixo, qiniseka ukuba uyazi ukuba loluphi uhlobo lwesixhobo sokuvala isitshixo ojongene naso. Kuba izixhobo zokuvala isitshixo ezahlukeneyo zineendlela ezahlukeneyo zokukhiya.
I-Miniature circuit breaker (MCB). Uhlobo oluqhelekileyo olufumaneka kwiibhokisi zokusasaza, kunye nee-levers ezimnyama ububanzi bomnwe, zicwangciswe ngemigca. Olu lolona hlobo lulula ukutshixa kwaye lunenani elikhulu lee-locks ezihambelanayo.
I-Frame circuit breaker (MCCB). Inkulu kune-MCB, inesiphatho esibanzi nesityebileyo kunye nomthamo ophezulu wamandla. Ihlala isetyenziswa kwikhabhathi ephambili yokusasaza kwindawo yokusebenzela okanye kwisekethe yombane yesixhobo esinye esikhulu. Isitshixo kufuneka silingane ngokuchanekileyo nobukhulu besiphatho.
Isixhobo sokwaphula isekethe yesakhelo (i-ACB). Uhlobo olukhulu, oluyintloko yamagumbi okusasaza amashishini. Isiphatho sikhulu kakhulu, kwaye ezinye zazo azingohlobo lwe-lever kodwa ziluhlobo lwesiphatho esijikelezayo. Indlela yokutshixa yahluke ngokupheleleyo kwiintlobo ezimbini zangaphambili.
Isixhobo sokwaphula isekethe esijikelezayo. Asisoswitshi sokutshintsha, kodwa sisitshitshi esijikelezayo esijikelezayo esingasetyenziswa ngesitshixo okanye ngesiphatho. Indlela yokutshixa kukuvala indlela ejikelezayo.
Isixhobo sokucofa iqhosha lokucofa. Ezinye izixhobo ezindala zisebenzisa uhlobo lweqhosha lokucofa. Ukuyicinezela phantsi KUVALIWE, kwaye ukuyikhupha KUVALIWE. Oku kufuna isitshixo sohlobo lwesiciko.
Icebiso lokuqala: Yiya ngaphambili kwikhabhathi yokusasaza uze uthathe imifanekiso yophawu kunye nomzekelo wohlobo ngalunye lwesiphatho sesekethe. Bamba ngokucacileyo imo, ububanzi besiphatho, kunye nendawo esecaleni kwaso. Emva koko, bonisa umthengisi iifoto ukuze anxibelelane. Oku kuthembeke ngokuphindwe kalikhulu kunokuchaza "malunga nobubanzi obungako" ngefowuni.
Iindidi ezininzi eziqhelekileyo zezitshixo ze-circuit breaker
1. Uhlobo lokungena/ Uhlobo lokubophelela – Uhlobo olulula
Olu hlobo lokutshixa lubotshelelwa ngqo kwi-lever ye-circuit breaker. Xa ivaliwe, kufakwa i-lock pin ngomngxuma wokutshixa ukuze iqine. Ukufakelwa akudingi zixhobo kwaye kunokugqitywa ngemizuzwana embalwa nje.
Umgaqo wayo ulula kakhulu: Nje ukuba i-lever ibambekile, i-lever ayikwazi ukuhamba. Xa ikhululwa, iyanamathela, ixhomekeke kwindawo efileyo yoomatshini.
Izinto ezisebenzayo: Ii-standard width miniature circuit breakers (ii-MCB), logama nje ububanzi be-lever bumalunga ne-8-12mm.
Zithini izithintelo? Xa usebenza ngee-levers ezibanzi kakhulu okanye ezimxinwa kakhulu, azinakubanjwa ngokukhuselekileyo. Kwakhona, kwiimeko apho ii-circuit breakers ezininzi zibekwe ecaleni kwaye kungekho ndawo yaneleyo yokusebenza kufutshane, ii-clamps azinakufakwa.
2. Uhlobo lokungena/lokuchwetheza – Lweziphuli-sekethe ezifakwe kwiphaneli
Ezinye ii-circuit breakers zinomngxuma omncinci ongqukuva ecaleni kwe-toggle lever, eyenzelwe ngokukodwa ukutshixa. Faka iphini encinci kulo mngxuma uze uwuqinise ngesitshixo, kwaye isiphatho siya kutshixwa.
Izinto ezisebenzayo: Ii-circuit breakers ezibunjiweyo zeplastiki ezine-built-in locking mechanism (MCCB), kunye nezinye ii-MCB ezikumgangatho ophezulu.
Iingenelo: Nje ukuba ifakiwe, iqinile kakhulu kwaye akunakwenzeka ukuba ikhutshwe. Iingxaki: Ukuba akukho mngxuma mncinci kangaka obekelwe iphaneli yakho ye-circuit breaker, ayizukunceda nganto.
3. Isitshixo seSibambo esijikelezayo – Sifanelekile kwiiSwitshi ezijikelezayo
Ulwakhiwo lwesiphatho esijikelezayo lwahlukile kweso sesitshixo sohlobo lwe-lever. Isitshixo se-lever asinakufakelwa kwaphela. Isitshixo sesiphatho esijikelezayo sidla ngokuba nesigqubuthelo okanye iringi yokubambelela, ebekwa ijikeleze isiphatho ukuze singajikelezi.
Ingqwalasela yoThenga: Ububanzi bangaphandle kunye nemilo yesiphatho. Ezinye zingqukuva, ezinye zithe tyaba, kwaye ezinye zinemingxuma yezitshixo. Umahluko wemilimitha ezimbalwa ngobukhulu uya kuyithintela ukuba ingangeni. Sebenzisa i-caliper ukuze ulinganise; ungaxhomekeki kuqikelelo olubonakalayo.
4. Ifakiwe / Uhlobo lwebhokisi - Ukutshixa umqolo wonke
Ukuba imigca emininzi yezaphuli-mibane kwikhabhathi yokusasaza kufuneka itshixwe ngaxeshanye, ukuzitshixa nganye nganye kuya kuba yinto engasebenzi kakuhle. Isitshixo esivalekileyo sisigqubuthelo seplastiki esibonakalayo esigubungela umqolo okanye iqela lonke lezaphuli-mibane. Sibotshelelwa ngesitshixo emva kokuba sibotshelelwe kakuhle.
Iingenelo: Itshixa isiqwenga ngasinye ngaxeshanye. Amanyathelo okhuseleko: Ifanelekile kwiibhokisi zokusasaza apho ii-circuit breakers zicwangciswe kakuhle kwaye zinesithuba esiqhelekileyo. Ukuba ii-circuit breakers kwibhokisi yokusasaza zigobile okanye isithuba asihambelani kakuhle, isigqubuthelo sisenokungavaleki kakuhle.
5. Uhlobo lwe-Universal / Tsala-ntonga – Indlela yokugqibela yokukhetha
Ezinye ii-circuit breakers zinemilo engaqhelekanga kangangokuba akukho nanye i-standard lock ehambelanayo. Kwiimeko ezinjalo, i-"pull-rod type" okanye i-"universal type" Circuit Breaker Lockout ingasetyenziswa - ngokuyintloko, yindlela yokutshixa ehlengahlengiswayo. Ngokuqinisa izikrufu okanye ukutsala intambo, iswitshi inokutshixwa kwindawo ethi OFF, ize emva koko ivalwe nge-padlock.
Inyaniso kukuba, ukuzinza kolu hlobo lokutshixa akulunganga njengokwezo zikhethekileyo. Kungasebenza, kodwa ukuba unenketho engcono, kungcono ukhethe ekhethekileyo. Uhlobo oluqhelekileyo lolona khetho lokugqibela kwaye alulo ukhetho lokuqala.
