KhethaCDADAnjengomvelisi wakho kunye nomthengisi. Ngokusekelwe e-China, sinika i-Residual Current Circuit Breaker kunye noKhuseleko lwe-Overcurrent, kunye noluhlu olubanzi lwezinye izixhobo zombane eziphantsi kwe-voltage. Singaphuhlisa izisombululo zobungcali, ezilungiselelwe ngokweemfuno zakho zeprojekthi; iimveliso zethu ziza newaranti yeminyaka emi-3 kwaye ithobela imigangatho eyahlukeneyo yehlabathi.

Yintoni i-RCBO?

I RCBO (Residual Current Circuit Breaker with Overcurrent Protection) sisixhobo esiyimodyuli esidibanisa ukusebenza kwe MCB (ISaphuli seSekethe esiNcinane)kunye ne RCCB (Intsalela yangoku yeSekethe yeSaphuli).

Ngelixa i-MCB ikhusela kuphela iintambo ekutshiseni (umthwalo ogqithisileyo) kunye nokungaphumeleli kwentlekele (isiphaluka esifutshane), kwaye i-RCCB ikhusela kuphela abantu ekuthukeni (ukuvuza), i-RCBO yenza konke. Ukuba impazamo iyenzeka-nokuba kukushukuma okukhulu okusuka kwisekethi emfutshane okanye kukuvuza okuncinci emzimbeni womntu-i-RCBO iyahamba, ihlukanise isekethe ngoko nangoko. Lo mandla umbini uwenza umgangatho wegolide wofakelo lombane lwendawo yokuhlala kunye norhwebo.

Iintlobo kunye noHlelo

Amandla ethu okwenza i-RCBO agubungela uluhlu olubanzi lolungelelwaniso lobugcisa ukuhlangabezana neemfuno zemarike yehlabathi.

Uhlobo / Uphawu	Inkcazo	Ugqaliselo lweSicelo
Ijika elijikajikayo	Uhlobo B (3-5 Ngaphakathi), Udidi C (5-10 Ngaphakathi), Udidi D (10-20 Ngaphakathi)	B: Indawo yokuhlala (izibane/iziseko). C: EzoRhwebo (iimoto/AC). D: Iindustrial (inrush ephezulu).
Uhlobo lwangoku olushiyekileyo	Type AC (Standard), Type A (Pulsating DC)	Uhlobo A luya lusiba semgangathweni kumakhaya anamhlanje anezixhobo zombane (oomatshini bokuhlamba, iiPC, iidrive ze-LED).
Iteknoloji	I-Electromagnetic vs. Electronic	I-Electromagnetic: Ukuthembeka okuphezulu, i-voltage-independent (ikhuselekile). I-Electronic: Icwebile, iyonga imali.
Iipali	1P+N (Imodyuli enye/18mm), 2P (Imodyuli ephindwe kabini/36mm),3P+N,4P	1P+N: Ugcino lwendawo yokuhlala. 2P: Ukwahlulwa ngokupheleleyo kushishino/kwezorhwebo.

ImiSebenzi enguNdoqo kunye neeNdlela zoKhuselo

I-RCBO iyamangalisa ye-miniaturization, izindlu ezimbini zeenkqubo zokukhusela ezihlukeneyo ngaphakathi kwendawo enye.

uKhuseleko oluGqibelekayo (Icandelo le-MCB):

Uhambo lweThermal: I-bimetallic strip iyatshisa kwaye igobe phantsi komthwalo omninzi, ngoomatshini ukhulula umtshini. Oku kukhusela iintambo ekunyibilikeni.

Uhambo lwemagnethi: Ikhoyili yesolenoid isabela kwiisekethi ezimfutshane zangoku eziphezulu, ikhubekisa isaphuli ngemilliseconds ukunqanda ugqabhuko-dubulo okanye umlilo.

Ukhuseleko lwangoku olushiyekileyo (Icandelo leRCCB):

Zero-Sequence Transformer: Uhlala ebeka iliso kwibhalansi phakathi kwemisinga eLive kunye neNeutral.

Ukufunyanwa kokuvuza: Ukuba ivuza langoku emhlabeni (umzekelo, ngomntu), ukungalingani kubangela isilayidi esibuthathaka esinyanzela abafowunelwa ukuba bavuleke.

Ukhuseleko oludibeneyo: Umatshini wangaphakathi uyilwe ukuze inkqubo (i-thermal/magnetic OKANYE intsalela) ikwazi ukuvusa i-latch yohambo, iqinisekise ukuba akukho mpazamo ingabonwa.

Izicelo eziphambili kunye namatyala okusetyenziswa

Ukwabiwa kwendawo yokuhlala: Ukukhusela iisekethi zomntu ngamnye (umzekelo, iisokethi zasekhitshini, izifudumezi zegumbi lokuhlambela) apho zombini ukugcwala kunye nokhuseleko lokothuka lufuneka kwindawo ethile yephaneli.

Izakhiwo zorhwebo: Ukuqinisekisa ukuqhubeka kwenkonzo. Ukuba impazamo yenzeka kwisekethe enye (umzekelo, i-PC ephosakeleyo), kuphela loo RCBO ethile ihamba, kunokuba i-RCCB engundoqo yokusika amandla kuwo wonke umgangatho.

Amandla ahlaziyekayo (Solar PV): Ukukhusela iisekethe ze-inverter kwiimpazamo zesitofu se-DC kunye nee-overcurrents.

Ulawulo lwemizi-mveliso: Ukukhusela iisekethi zolawulo olubuthathaka kunye neenjini kwiimpazamo zesigaba ukuya emhlabeni.

Ukwenziwa ngokuchanekileyo: Ukusuka kwiMathiriyeli ekrwada ukuya kwiMveliso egqityiweyo

Ukuvelisa i-RCBO kunzima kakhulu kunokuvelisa i-MCB okanye i-RCCB ngokwahlukeneyo, njengoko kufuna ungqamaniso olugqibeleleyo lweendlela ezimbini ezahlukeneyo.

1. Izinto ezingundoqo:

Izindlu: I-High-grade, i-flame-retardant Polyamide (PA66) okanye i-Polycarbonate ukumelana nobushushu obuveliswa zizinto ezimbini zokhuseleko.

Inkqubo yoQhagamshelwano: Silver-Tin-Oxide (AgSnO2) abafowunelwa abakwaziyo ukuphatha imisinga yomoya emfutshane ephezulu kunye nokuvuza rhoqo.

IIMagnetic Core: Permalloy okanye Nanocrystalline cores yesiguquli sokubona ukuvuza.

Iyunithi yohambo: Indibano entsonkothileyo edibanisa i-bimetallic strip, i-solenoid coil, kunye nepolarized magnetic relay.

2. IMveliso kunye noKusetyenzwa komsebenzi:

I-I-Sub-Assembly: Isixhobo se-MCB (i-thermal/magnetic) kunye ne-RCCB indlela (isitshintshi/isidluliseli) zidityaniswe kwimigca eyahlukeneyo.

Ukudityaniswa: Ezisistim zimbini zidityanisiwe. "Ibar yohambo" ilinganiswe ukuze amandla omatshini asuka kumthwalo ogqithisiweyo okanye ubhaqo lokuvuza akwazi ukukhulula abafowunelwa ngempumelelo.

Iintambo: Iziqhagamshelo zangaphakathi eziguquguqukayo zidityaniswe ngokuchaneka ukuqinisekisa ukuxhathisa okuphantsi kunye nokuba bhetyebhetye koomatshini.

Ukulinganisa kabini: Eli lelona nyathelo libaluleke kakhulu. Iyunithi ivavanyelwa i-Amperage (In) (e.g., 16A) kunye neLeakage (IΔn) (umzekelo, 30mA). Zombini kufuneka zilinganiswe ngokugqibeleleyo ukuze iyunithi idlule.
