Incazelo Yemikhiqizo
Uchungechunge lwe-ETM7RF RCBO lusebenza emshinini wokusabalalisa amandla kagesi aphansi embonini, isakhiwo somphakathi njengekhaya nendawo yokuhlala, amandla, ukuxhumana, ingqalasizinda, isistimu yokusabalalisa izibani noma ukusatshalaliswa kwezimoto nezinye izinkambu.Zihlinzeka ngokuvikela ukuvuza, ukuvikela isifunda esifushane, ukuvikela ukugcwala ngokweqile, nokuvikela ukuhlukaniswa, okungavikela umuntu ekulimaleni okubangelwa ukuvuza kwamandla, ikakhulukazi ngenkathi ekwazi ukuvikela isekethe nezinto zikagesi engozini yesibili ebangelwa ukugcwala nokufushane. isifunda.
I-ETM7RF yochungechunge lwe-RCBO ihambisana ne-IEC 61009-1standard.
Umthamo wokuphuka we-ETM7RF yi-10KA, noma i-6KA
Uhlobo lokukhubeka lwesekethe elifushane yi-B, C curve.
Isilinganiso samanje singu-6A, 10A, 16A, 20A, 25A, 32A, 40A.Amandla amanje alinganisiwe ahlobene nendawo ehlukene kusetshenziswa isibonelo isigxobo esisodwa esingu-10 kuya ku-16 i-ampere ngokuvamile sisetshenziselwa ukukhanyisa, ama-ampere angama-20 kuye kwangama-33 ngokuvamile asetshenziselwa ekhishini nendawo yokugezela, aphinde asetshenziselwa isifudumezi-moya nezinye izinto zokusebenza.
Ukuzwela kwamanje kwe-Residual Current, noma i-Earth Leakage tripping ngu-10mA, 30mA, 100mA, kuyilapho i-10mA kanye ne-30mA isetshenziswa kakhulu ekujikelezeni kwegumbi lokugeza nekhishi ukuvikela umuntu ekushayweni wugesi.
Uhlobo lokukhubeka lwe-Residual current yi-AC noma i-A class.I-AC class Tripping iqinisekiswa kuma-sinusoidal, ama-alternating currents, noma ngabe asetshenziswa ngokushesha noma akhuphuka kancane .I-Class Tripping iqinisekiswa kuma-sinusoidal, ama-residual currents ashintshanayo kanye namaza asele e-DC ashayayo, kungakhathaliseki ukuthi asetshenziswa ngokushesha noma akhuphuka kancane .
I-voltage elinganiselwe: 230V/240V (Isigaba nokumaphakathi)
Kukhona inkomba yesikhundla efakwe emikhiqizweni, Okubomvu kuvuliwe, Okuluhlaza kuvaliwe.
Amatheminali e-RCBO ayisivikelo se-IP20 esidizayinelwe ukuthinta umunwe nesandla kuphephile ukuze kugcinwe ukuphepha ngesikhathi sokufakwa.
I-ETM7RF RCBO ingasebenza ngokuthembekile endaweni enzima, endaweni yokushisa ephakathi -25°C kuya ku-55°C.
Impilo kagesi ingaba imisebenzi efinyelela ku-8000 kanye nempilo yemishini kuze kufike ku-20000, kuyilapho imfuneko ye-IEC ingukusebenza okungu-4000 kanye nokusebenza okungu-10000 kuphela.
Uhlobo lokukhweza lwamatheminali uhlobo lwepulaki ohlangothini lokokufaka, kanye nohlobo lwezintambo ohlangothini oluphumayo.
Yini i-RCBO?
I-RCBO imele i-Residual Current Breaker enokuvikelwa Kwamanje.I-RCBO ihlanganisa ukusebenza kwe-MCB ne-RCD/RCCB.Uma kukhona ukuvuza kwamanje, i-RCBO ijikeleza yonke isekethe.Ngakho-ke, izingxenye zangaphakathi ze-magnetic/thermal circuit breaker zingakhuba idivayisi ye-elekthronikhi lapho isekethe igcwele kakhulu.
1. I-Residual Current, noma Ukuvuza Komhlaba - Kwenzeka uma kuba nephutha ngephutha isekethe ngenxa yezintambo zikagesi ezingezinhle noma izingozi ze-DIY ezifana nokubhoboza ngekhebula lapho ugxumeka ihuku lesithombe noma ukusika ikhebula elinomshini wokugunda utshani.Kulokhu ugesi kufanele uye ndawana thize bese ukhetha umzila olula odlula kumshini wokugunda utshani noma ubhoboze uye kumuntu obangela ukushaqeka kukagesi.
2. I-Over-current ithatha izinhlobo ezimbili:
a.Ukulayisha Okuningi - Kuvela lapho kusetshenziswa amadivayisi amaningi kakhulu kusekethe, kudweba inani lamandla elidlula umthamo wekhebuli.
b.Isifunda Esifushane - Kwenzeka uma kunokuxhumana okuqondile phakathi kwamakhondaktha abukhoma naphakathi nendawo.Ngaphandle kokumelana okunikezwa ubuqotho besekethe evamile, amandla kagesi agijima azungeze isekethe ngeluphu futhi aphindaphinde i-amperage izikhathi eziyizinkulungwane ngama-millisecond nje futhi kuyingozi kakhulu kunokulayisha Okungaphezulu.
Nakuba i-RCCB yakhelwe ukuvikela kuphela ekuvuzeni komhlaba futhi i-MCB ivikela kuphela esikhathini esidlule, i-RCBO ivikela kuzo zombili izinhlobo zephutha.
Ngokuphatha kwethu okuhle kakhulu, amakhono aqinile ezobuchwepheshe kanye nezindlela eziqinile zokulawula ikhwalithi ephezulu, siyaqhubeka nokunikeza abathengi bethu ikhwalithi enokwethenjelwa, ububanzi bentengo obuzwakalayo nabahlinzeki abahle kakhulu.Sihlose ukuba omunye wozakwethu abathembeke kakhulu futhi sikunikeze ama-circuit breaker asebenzayo asezingeni eliphezulu, siyalamukela ithuba lokwenza ibhizinisi nawe futhi singathanda ukuhlonipha ukunamathisela imininingwane eyengeziwe yemikhiqizo yethu.Ukusebenza okuphezulu kwe-Chinese residual current circuit breaker switches, sinikeza inhlobonhlobo yemikhiqizo kulo mkhakha.Ngaphezu kwalokho, ama-oda wangokwezifiso nawo ayatholakala.Ngaphezu kwalokho, uzojabulela isevisi yethu yekhwalithi ephezulu.Ngamafuphi nje, ukwaneliseka kwakho kuqinisekisiwe.Siyakwamukela ukuvakashela inkampani yethu!Ukuze uthole ulwazi olwengeziwe, sicela uvakashele iwebhusayithi yethu.Uma uneminye imibuzo, sicela ukhululeke ukuxhumana nathi.
Njengamanje, lolu hlobo lwedivayisi yokuvikela ukuvuza yilo olusetshenziswa kakhulu.Amaswishi okuvikela ukuvuza emakethe avame ukusetshenziswa ezigabeni ezilandelayo ngokuya ngemisebenzi yawo:
(1) Inomsebenzi wokuvikela ukuvuza kuphela kanye nokucisha amandla, futhi kufanele isetshenziswe nezinto ezivikelayo ezifana nama-fuse, ama-thermal relay, nama-overcurrent relay.
(2) Ngesikhathi esifanayo, inomsebenzi wokuvikela ukulayisha ngokweqile.
(3) Ngesikhathi esifanayo, inomthwalo omningi kanye nemisebenzi yokuvikela isifunda esifushane.
(4) Ngesikhathi esifanayo, inomsebenzi wokuvikela isifunda esifushane.
(5) Ngesikhathi esifanayo, inemisebenzi ye-short circuit, overload, ukuvuza, overvoltage kanye undervoltage.Isokhethi yokuvikela ukuvuza isho isokhethi yamandla enekhono lokubona nokwahlulela umsinga ovuzayo futhi inqamule isekethe.Amanje alinganiselwe ngokuvamile angaphansi kuka-20A, amanje avuzayo angu-6-30mA, futhi ukuzwela kuphezulu uma kuqhathaniswa.
