1P+N, RCBO, B, C curve, ETM8RF , I-Residual Current Breaker enokuvikelwa Kwamanje, i-din rail
Incazelo Yemikhiqizo
Uchungechunge lwe-ETM8RF RCBO lusebenza emshinini wokusabalalisa amandla kagesi aphansi embonini, isakhiwo somphakathi njengekhaya nendawo yokuhlala, 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-ETM8RF yochungechunge lwe-RCBO ihambisana ne-IEC 61009-1standard.
Umthamo wokuphuka we-ETM8RF 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-ETM8RF RCBO ingasebenza ngokwethembeka endaweni enokhahlo, 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.
Empilweni yangempela, izakhi zikagesi njengezinqamuleli zesekethe eziyinsalela (ezaziwa ngokujwayelekile ngokuthi amaswishi avuzayo) zisetshenziswa cishe kuzo zonke izindawo ezinogesi.Isetshenziselwa kakhulu ukuthola amandla asele, ukuqhathanisa inani lamanje elisele nenani lesithenjwa, futhi kunqanyulwe othintana naye wesekethe oyinhloko lapho inani lamanje elisele lidlula inani lereferensi.Lapho ukushaqeka kukagesi komuntu siqu noma ukuvuza kwegridi kudlula inani elishiwo, i-circuit breaker esele inganqamula ngokushesha ukunikezwa kwamandla okungalungile ngesikhathi esifushane kakhulu, ivikele ukuphepha kwemishini yomuntu siqu nekagesi, futhi ngesikhathi esifanayo ivikele ugesi ongalungile. ukulayisha ngokweqile noma isifunda esifushane somugqa kanye nemoto, futhi Ingasetshenziselwa ukushintsha okungajwayelekile kwemigqa kanye nokuqala okungajwayelekile kwamamotho, futhi iyisisetshenziswa sikagesi esisetshenziswa kabanzi ekukhiqizeni nasekuphileni.
1. I-relay yokuvikela ukuvuza ibhekisela kudivayisi yokuvikela ukuvuza enomsebenzi wokuthola nokwahlulela amandla avuzayo, kodwa engenawo umsebenzi wokusika nokuxhuma isifunda esikhulu.I-relay yokuvikela ukuvuza yakhiwe yi-zero-sequence transformer, ukukhululwa kanye nokuxhumana okuyisizayo kwesignali yokuphumayo.Ingakwazi ukusebenzisana nokushintsha okuzenzakalelayo kwamandla aphezulu njengesivikelo esijwayelekile segridi yamandla kagesi aphansi noma ukuvuza, ukubeka phansi noma ukuvikelwa kokuqapha komgwaqo omkhulu.Lapho kukhona ukuvuza kwamanje kumjikelezo oyinhloko, njengoba othintana naye osizayo kanye nokukhululwa kokuhlukaniswa kwe-switch yesifunda esikhulu kuxhunywe ochungechungeni ukuze kwakhiwe isekethe, othintana naye osizayo uxhunywe ekukhishweni kokuhlukanisa futhi anqamule inkinobho yomoya, i-AC contactor, njll. iluphu.Oxhumana nabo abasizayo nabo bangaxhunywa kumadivayisi esignali yomsindo neyokukhanya ukuze kukhishwe isignali ye-alamu yokuvuza ukuze ibonise isimo sokufakwa komugqa.2. Iswishi yokuvikela ukuvuza isho ukuthi ayikwazi kuphela ukuvula noma ukuvala isifunda esikhulu njengamanye ama-circuit breaker, kodwa futhi inomsebenzi wokuthola nokwahlulela ukuvuza kwamanje.Uma ukuvuza noma ukulimala kokufakelwa kwenzeka kumjikelezo oyinhloko, ukushintshwa kokuvikela ukuvuza kungase kusekelwe Isici sokushintsha esivula noma sivale isifunda esikhulu ngenxa yesahlulelo.Isebenzisana namafuse kanye nama-thermal relay ukuze kwakheke isici sokushintsha esinogesi ophansi esisebenza ngokugcwele.
