Chii chinonzi RCBO?
RCBO inomirira Residual Current Breaker ine Over-Current protection.Iyo RCBO inosanganisa kushanda kweMCB uye RCD/RCCB.Kana paine kuvuza kwazvino, RCBO inofamba dunhu rese.Nekuda kweizvozvo, zvemukati magineti / zvinopisa wedunhu breaker zvikamu zvinogona kutsika mudziyo wemagetsi kana dunhu raremerwa.
1. Residual Current, kana Earth Leakage - Inoitika kana pakaita netsaona kuputsika kwedunhu kuburikidza nemagetsi asina kunaka ewaya kana tsaona dzeDIY dzakadai sekuboora netambo paunenge uchiisa chiredzo chepikicha kana kucheka netambo ine lawn mower.Muchiitiko ichi magetsi anofanirwa kuenda kumwe uye kusarudza nzira iri nyore kufamba nemuchina chekuchenura kana kudhiraivha kuenda kumunhu zvichikonzera kuvhunduka kwemagetsi.
2. Over-Curent inotora mafomu maviri:
a.Overload - Inoitika kana midziyo yakawandisa iri kushandiswa padunhu, ichidhirowa huwandu hwesimba rinopfuura kugona kwetambo.
b.Short Circuit - Inoitika kana paine hukama hwakananga pakati pevanogara uye vasina kwavakarerekera conductors.Pasina kupokana kunopihwa neakajairika wedunhu kuperera, magetsi emagetsi anomhanya achitenderedza dunhu muchiuno uye anowedzera amperage nezviuru zvakapetwa mumamilliseconds uye ane njodzi zvakanyanya kupfuura Overload.
Ipo RCCB yakagadzirirwa chete kudzivirira kubva mukudonha kwepasi uye MCB inodzivirira chete kubva kune-izvino, RCBO inodzivirira kubva kumarudzi ese ekukanganisa.
Kuti tirambe tichivandudza maitiro ekutonga, zvinoenderana nemusimboti we "kutendeseka, kukudzwa, mhando ndiyo hwaro hwekusimudzira bhizinesi", isu pamwe chete tinotora izvo zvakakosha zvezvigadzirwa zvepasi rese nemhinduro, uye tinogara tichivaka mhinduro nyowani dzekuzadzisa zvinodiwa nevatengi. .Vatengi vemhando yepamusoro-soro yeChinese yasara inotyora matunhu, ine sevhisi yakanakisa uye mhando yakanaka, pamwe nebhizimusi rekutengeserana kunze kwenyika rinoratidza kushanda uye kukwikwidza, vachavimbwa nekugamuchirwa nevatengi vavo uye kuunza mufaro kuvashandi.Yepamusoro-soro yakasara yemazuva ano mabreaker akagamuchira rumbidzo yepamusoro kubva kune wese mutengi.Kambani yedu yanga ichiomerera kune dzidziso ye "mutengi kutanga", uye yakazvipira kubatsira vatengi kuwedzera bhizinesi ravo nekuvaita mabhosi makuru!
Iyo leakage mudziviriri ine yakakwira senitivity uye nekukurumidza kuita mukupindura kuvhunduka kwemagetsi uye kudzivirirwa kwekuvhara, iyo isingaenzaniswi nezvimwe zvinodzivirira midziyo yakadai semafuse uye otomatiki switch.Kana iyo otomatiki switch uye fuse zvakajairika, ivo vanofanirwa kupfuudza mutoro wazvino, uye kukosha kwavo kwekudzivirira kunofanirwa kusetwa kuti vadzivise yakajairika mutoro wazvino, saka basa ravo guru nderekucheka chikamu-ku-chikamu chipfupi-chikanganiso chedunhu. iyo sisitimu (dzimwe otomatiki switch zvakare dzine yakawandisa kuchengetedza basa. ).Iyo leakage mudziviriri inoshandisa yasara ikozvino yehurongwa kuita uye kuita.Munguva yekushanda kwakajairika, iyo yakasara ikozvino yehurongwa inenge zero, saka kukosha kwayo kwekuita kunogona kuiswa kudiki kwazvo (kazhinji maA level).Kana iyo sisitimu iine kuvhunduka kwemagetsi kana midziyo Kana goko rachajwa, hombe yakasara inoitika, uye inodzivirira yekudonha inoita yakavimbika mushure mekuona uye kugadzirisa yasara ikozvino kuti ibvise magetsi.
