Incazelo Yemikhiqizo
Uchungechunge lwe-ETM3RF RCBO lusebenza emshinini wokusabalalisa amandla kagesi aphansi embonini, isakhiwo somphakathi njengekhaya nokuhlala, amandla, ukuxhumana, ingqalasizinda, uhlelo lokusabalalisa 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-ETM3RF yochungechunge lwe-RCBO ihambisana ne-IEC 61009-1standard.
Umthamo wokuphuka we-ETM3RF 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-ETM3RF 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 lwayo lokukhweza kufanele lufakwe ku-din rail EN60715 35mm.
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.
Ukuze sithuthukise ngokuqhubekayo inqubo yokuphatha, ngokuhambisana nesimiso esithi "abaqotho, abahloniphekile, ikhwalithi iyisisekelo sokuthuthukiswa kwebhizinisi", sibamba ngokuhlanganyela ingqikithi yemikhiqizo yamazwe ngamazwe efanele nezisombululo, futhi sakhe njalo izixazululo ezintsha ukuhlangabezana nezidingo zamakhasimende. .Abathengi bekhwalithi ephezulu yama-circuit breaker amanje aseShayina, anesevisi enhle kakhulu nekhwalithi enhle, kanye nebhizinisi lohwebo lwangaphandle elibonisa ukusebenza kahle nokuncintisana, bazothenjwa futhi bamukelwe abathengi babo futhi balethe injabulo kubasebenzi.Ama-circuit breaker amanje asezingeni eliphezulu athole ukunconywa okuphezulu kakhulu kuwo wonke amakhasimende.Inkampani yethu ibilokhu ibambelela kumgomo othi "ikhasimende kuqala", futhi izibophezele ekusizeni amakhasimende ukuthi akhulise ibhizinisi lawo futhi awenze abaphathi abakhulu!
Isivikeli sokuvuza sinokuzwela okuphezulu kanye nesenzo esisheshayo ekuphenduleni ukushaqeka kukagesi nokuvikelwa kokuvuza, okungenakuqhathaniswa nezinye izinto ezivikelayo ezifana nama-fuse kanye nokushintsha okuzenzakalelayo.Uma ukushintshwa okuzenzakalelayo kanye ne-fuse kujwayelekile, kufanele kudlule umthamo wamanje, futhi inani labo lokuvikela isenzo kufanele libekwe ukuze kugwenywe umthamo ovamile wamanje, ngakho umsebenzi wabo oyinhloko ukunqamula iphutha le-short-circuit lesigaba nesigaba uhlelo (amanye amaswishi azenzakalelayo nawo anomsebenzi wokuvikela ukugcwala ngokweqile. ).Isivikeli sokuvuza sisebenzisa amandla asele esistimu ukuze asabele futhi enze okuthile.Ngesikhathi sokusebenza okuvamile, amandla asalayo esistimu acishe abe yiziro, ngakho-ke inani laso lokusetha isenzo lingasethwa libe lincane kakhulu (imvamisa izinga le-mA).Uma uhlelo lunokushaqeka kukagesi noma okokusebenza Lapho igobolondo lishajwa, kuvela umsinga omkhulu oyinsalela, futhi isivikelo sokuvuza sisebenza ngokwethembeka ngemva kokuthola nokucubungula amandla asalayo ukuze kunqandwe ukunikezwa kwamandla.
