Okokuqala, makhe sihlalutye umsebenzi wei-low voltage circuit breakerkunye ne-fuse kwisekethe yombane yombane ophantsi:

1. I-Voltge Low Circuit Breakers

Isetyenziselwa ukukhuselwa komthwalo wangoku ekupheleni kokunikezelwa kwamandla, ukukhuselwa kwangoku komthwalo kwi-trunk kunye neziphelo zesebe lemigca yokusabalalisa, kunye nokhuseleko lwangoku lomthwalo ekupheleni kwemigca yokusabalalisa.

Xa i-overload, isiphaluka esifutshane, okanye ilahleko ye-voltage iyenzeka kumgca, uhambo olukhawulezayo lwe-low-voltage breaker circuit breaker off the power supply ukukhusela ukhuseleko lomgca.

Isaphuli seSekethe eshiyekileyoIsetyenziselwa uKhuseleko loMothuko woMntu

2. Iifusi

Isetyenziselwa ukukhuselwa kokugqithiswa komthwalo wangoku kumgca kunye nokukhusela isiphaluka esifutshane phakathi kwesigaba kunye nesigaba kunye nomhlaba ohambelanayo.

I-fuse sisixhobo sokukhusela.Xa i-current idlula ixabiso elimiselweyo kwaye idlula ixesha elaneleyo, i-melted iyancibilika, kwaye isiphaluka esixhunywe kuyo sinqanyuliwe, esibonelela ngokukhuselwa kokugqithiswa okanye ukukhuselwa kwesiphaluka esifutshane kwisiphaluka kunye nezixhobo.

Ngohlalutyo olulula, kunokwaziwa ukuba ii-breakers zesekethe kunye ne-fuses kufuneka zifakwe kwizixhobo zombane zombane ophantsi, nokuba zisetyenziselwa ushishino okanye ukusetyenziswa kwekhaya.

Ngaba ubugcisa bombane bonke bayazi: Umsebenzi wombane kufuneka uhambelane ngokunyanisekileyo "neMimiselo yeSixhobo soMbane esisezantsi".Kukho izahluko ezibini kwi-"Low Voltage Electrical Device Regulations" eziqulunqa ngokukodwa iinkcukacha zofakelo lwe-switch enkulu (i-breaker circuit) kunye ne-fuse.

Ukudibanisa i-breaker circuit kunye ne-fuse kunye nokudibanisa ucingo kufuneka kwakhona kuqwalaselwe kwisixhobo sesekethe sangempela.

I-fuse yangoku ye-fuse yefowuni kwisekethe kufuneka ibe mkhulu okanye ilingane ne-1.2 ukuya kwi-1.3 amaxesha ombane olinganisiweyo we-breaker circuit.

I-melting current ye-fuse ingaphantsi kwamaxesha angama-0.8 okhuseleko lwangoku lomqhubi wocingo.

Ngokuqhelekileyo, umsinga onyibilikayo we-fuse kufuneka ube mkhulu kunomlinganiselo obekiweyo we-breaker circuit kwaye ube ngaphantsi komthamo okhuselekileyo wokuthwala we-conductor.

Umlinganiselo olinganisiweyo we-circuit breaker kufuneka ube mkhulu okanye ulingane nomgca womgca, kwaye umgca wokulayisha umgca kufuneka ube ngamaxesha angama-1.2 njengomthwalo wangoku.Iyakwazi ukulungelelanisa umthwalo womgca ngokufanelekileyo ngokwendalo yomthwalo womgca, njengokufudumala kombane.Kodwa i-current rated current ye-breaker circuit kufuneka ibe ngaphantsi kwe-fuse melt current.

Ukongezelela, kukho izixhobo ezininzi zeesekethe ezingenazo iifuse, ezingakhuselekanga kwaye zingachanekanga.Xa kukho impazamo emgceni, kulula kakhulu ukubangela umlilo.Ngaphambili iingozi zomlilo, iifusi zazingafakelwanga okanye zifakwe kakubi.Zininzi izifundo ekufuneka zifundwe.Ngoko ke, i-fuses kunye ne-circuit breakers kufuneka zifakwe kwi-decoration yasekhaya.Ungaze ube nokungakhathali kwaye ukhuseleke kuqala.
