Kutheni ii-MCBs zihamba rhoqo? Ukuphepha njani ukukhubeka kwe-MCB?

Iimpazamo zombane zinokutshabalalisa ubomi obuninzi ngenxa yokugcwala okanye iisekethe ezimfutshane, kunye nokukhusela ekugqithiseni kunye nakwisekethe emfutshane, kusetyenziswa iMCB.Abaphuli beSekethe abancinci(MCBs) zizixhobo ze-electromechanical ezisetyenziselwa ukukhusela isiphaluka sombane kwi-Overload & Short Circuit. Izizathu eziphambili ze-overcurrent ingaba yisekethe emfutshane, i-overload okanye idizayini ephosakeleyo. Kwaye apha kule bhlog, siza kube sikuxelela isizathu sokuba i-MCB igibele rhoqo kunye neendlela zokuyinqanda. Apha, jonga!

Izinto eziluncedo ze-MCB:

● Isekethi yombane iyazicima ngokuzenzekelayo xa kuvela imeko engaqhelekanga yothungelwano

● Indawo engalunganga yesekethe yombane inokuchongwa ngokulula, njengoko iqhosha lokusebenza liphuma kwindawo ngexesha lokukhubeka.

● Ukubuyisela ngokukhawuleza unikezelo kunokwenzeka kwimeko ye-MCB

● I-MCB ikhuseleke ngakumbi ngombane kune-fuse

Iimpawu:

● Amaxabiso akhoyo angekho ngaphezulu kwe-100A

● Iimpawu zohambo zidla ngokungalungelelanisi

● Ukusebenza kwe-Thermal kunye nemagnethi

Iimpawu kunye neenzuzo ze-MCB

1. Ukhuseleko ngokuchasene nokothuka nomlilo:

Okokuqala kunye neyona nto ibalulekileyo ye-MCB kukuba inceda ekupheliseni uqhagamshelwano ngengozi. Iyaqhutywa kwaye ilawulwe ngaphandle kwengxaki.

2. Abafowunelwa be-Anti welding:

Ngenxa yepropati echasene ne-welding, iqinisekisa ubomi obuphezulu kunye nokhuseleko olungaphezulu.

3. Itheminali yokhuseleko okanye izikrufu ezibanjwayo:

Uhlobo lwebhokisi uyilo lwetheminali lubonelela ngokupheliswa okufanelekileyo kwaye lunqanda unxibelelwano oluxekileyo.

Izizathu zokuba kutheni ii-MCBs zihamba rhoqo

Kukho izizathu ezi-3 zee-MCBs ezikhubeka rhoqo:

1. Isekethe egcwele kakhulu

Ukulayisha ngaphezulu kwesekethe kwaziwa njengesona sizathu sixhaphakileyo sokukhubeka kwe-breaker circuit. Kuthetha nje ukuba sisebenzisa izixhobo ezininzi ezisebenzisa amandla anzima ngaxeshanye kwisekethe enye.

2. Isiphaluka esifutshane

Isizathu esilandelayo esiyingozi kakhulu yisekethe emfutshane. Isiphaluka esifutshane senzeke xa ucingo / isigaba sithinta enye intambo / isigaba okanye ibambe ucingo "oluphakathi" kwisekethe. Ukuhamba okuphezulu kwangoku xa ezi ngcingo zimbini zichukumisa ukudala ukuhamba kwangoku okunzima, ngaphezu kokuba isekethe inokusingatha.

3. Impazamo ephantsi

Impazamo yomhlaba iphantse ifane nesekethe emfutshane. Eli tyala lenzeka xa ucingo olushushu luchukumisa ucingo lomhlaba.

Ngokusisiseko, sinokuthi umzuzu xa isekethe iqhawuka, ithetha ukuba yangoku idlula ii-AMPs inkqubo yakho ayikwazi ukuyiphatha, okt inkqubo igcwele kakhulu.

Izaphuli sisixhobo sokhuseleko. Yenzelwe ukukhusela izixhobo kuphela kodwa i-wiring kunye nendlu ngokunjalo. Ke, xa i-MCB ihamba, kukho isizathu kwaye esi salathisi kufuneka sithathwe ngokubaluleke kakhulu. Kwaye xa useta kwakhona i-MCB, kwaye iphinda ihambe kwakhona, ngoko idla ngokubonisa imfutshane ngqo.

Esinye isizathu esiqhelekileyo sokuba i-breaker ihambe kukudityaniswa kombane okuxekethileyo kwaye kunokulungiswa ngokulula ngokuziqinisa.

Ezinye iingcebiso ezibalulekileyo zokuthintela ukukhubeka kwe-MCBs

● Kufuneka sizikhuphe zonke izixhobo xa zingasetyenziswa

● Sifanele siqaphele ukuba zingaphi izixhobo zombane ezifakelweyo xa kushushu okanye kubanda

● Kufuneka uqinisekise ukuba akukho nanye kwintambo yesixhobo sombane eyonakeleyo okanye yophukileyo

● Kuphephe ukusebenzisa intambo yokwandisa kunye neentambo zombane ukuba uneendawo ezimbalwa zokuphuma

Iisekethe ezimfutshane

Iihambo zesaphuli sesekethe zivela xa isixokelelwano sakho sombane okanye esinye sezicelo osisebenzisayo sifutshane. Kwamanye amakhaya, kunzima ukubona ukuba iphi na imfutshane. Kwaye ukufumana ukufutshane kwisixhobo, sebenzisa inkqubo yokuphelisa. Vula umbane kwaye uplage isixhobo ngasinye nganye nganye. Jonga ukuba isixhobo esithile sibangela uhambo oluqhekezayo.

Ke, kungenxa yoko le nto i-MCB ihamba rhoqo kunye neendlela zokunqanda ukuhamba kwe-MCB.
