Ukulungiswa Kwesimo Nokusethwa Kwepharamitha Kubalulekile Ekukhethweni Kwe-RCBO

Ekukhetheni ukusatshalaliswa kwamandla ane-voltage ephansi, abathengi abaningi banombono ongalungile ovamile: lapho ukuzwela kwe-I-Residual Current Breaker enesivikelo se-Overcurrent, ukusetshenziswa kwamandla kuzoba kuphephile kakhulu. Eqinisweni, ingqikithi yokuvikelwa kwamanje okusele itholakala ekuzivumelaniseni nezimo kanye nokusetha amapharamitha ochwepheshe, kunokulandela ngokungazi lutho ukuzwela okuphezulu kakhulu.

Izilungiselelo zokuzwela okuphezulu ngokungafanele zingabangela kalula ukukhubeka njalo kwezinkinga kanye nokuphazamiseka kokunikezwa kwamandla okungalindelekile. Kuphela ngokuqhathanisa imingcele yezobuchwepheshe ngokuhambisana nomqondo wobungcweti wemboni lapho singalinganisela khona ngokuphelele ukuphepha komuntu siqu, ukuzinza kokusebenza kwemishini kanye nokuthembeka kwezintambo zikagesi.

I-Rated Residual Operating Current (IΔn) iyipharamitha yokusetha eyinhloko ye-residual current breaker enokuvikelwa kwe-overcurrent. Izilinganiso zamanje ezijwayelekile zifaka phakathi i-30mA, i-100mA kanye ne-300mA, kanti isilinganiso ngasinye sinomqondo wokuvikela ozimele ngokuphelele.

Imodeli engu-30mA ingeyamazinga okuzwela okuphezulu, eyenzelwe ngokukhethekile ukuvikelwa kokushaqeka kukagesi komuntu siqu. Amazinga angu-100mA kanye no-300mA ayizinketho zokuzwela okuphakathi nokuphansi, ezigxile ekuvimbeleni umlilo kagesi kanye nokuvikelwa kwemishini yamandla.

Uma amadivayisi angu-30mA anozwela oluphezulu esetshenziswa ngenkani ezimweni zezimboni nezentengiselwano ezinomthwalo omningi, ukuvuza okuvamile kwemishini yokusebenza kuzobangela ukukhubeka okungadingekile futhi kuphazamise ukunikezwa kwamandla ebhizinisi nawokukhiqiza. Ngokuphambene nalokho, ukusebenzisa ama-breaker anozwela oluphansi ezindaweni zokuhlala nezentengiselwano ezinabantu abaningi kwehluleka ukunqamula ugesi ngokushesha ngesikhathi sezingozi zokushaqeka kukagesi, okuletha izingozi ezinkulu zokuphepha ezingaba khona.

I-logic yokukhetha yobungcweti yamapharamitha okuvikela amanje asele ngokusekelwe ezimweni zohlelo lokusebenza icacile futhi ijwayelekile:

1.Izimo Zokuhlala Nezomphakathi

Beka ukuphepha komuntu siqu phambili futhi usebenzise i-residual current elinganiswe ngo-30mA. Ifanelekela amasekethe esigaba esisodwa angu-230V, imboza amasekethe okukhanyisa, amasokhethi kanye nekhishi kanye negumbi lokugezela lapho kulula khona ukuthinta izingxenye eziphilayo, okwenza kube lula ukunqamula ugesi ngokushesha ukuze kugwenywe izingozi zokushaqeka kukagesi.

2.Izimo Zezentengiselwano Nezimboni Ezilula

Linganisa ukuphepha kanye nokuzinza kokusebenza ngesethingi engu-100mA. Igwema ngempumelelo ukukhubeka okubangelwa ukuvuza okuvamile kwemishini enamandla amakhulu ezitolo ezinkulu kanye nasezimbonini ezincane, ngenkathi inikeza ukuvikelwa komlilo kagesi okuthembekile.

3.Izimo Zokusabalalisa Amandla Ezimboni Nezinzima

Gxila ekuvikelweni komugqa wamandla kanye nemishini ngesilinganiso esingu-300mA. Ilungele izinhlelo zokusatshalaliswa kwamandla zezigaba ezintathu ze-400V, ivumelana nezimo zokusebenza ezikude nezimo zokusebenza ezisindayo ukuqinisekisa ukunikezwa kwamandla okuqhubekayo nokuzinzile.

Ukuze kuhlangatshezwane nezidingo zokukhetha ezisekelwe esimweni esingenhla,Ugesi Wabantu RDL8-40 Uchungechunge lwe-RCBOIhlinzeka ngesisombululo sobungcweti esiphelele. Ngokuhambisana ngokuqinile nezindinganiso zomhlaba wonke ze-IEC/EN61009, lolu chungechunge lusekela ugesi osebenzayo osele olungisekayo ongu-30mA/100mA/300mA, kanye nogesi olinganiselwe osukela ku-6A kuya ku-40A.

Itholakala ngezilungiselelo ze-pole ze-1P+N kanye ne-3P+N, ihambisana ngokugcwele nezinhlelo zokusabalalisa amandla ze-230/400V, 50/60Hz AC kanye ne-DC. Ihlanganisa ukuvikelwa kwe-overcurrent, i-short circuit kanye ne-residual current triple, umklamo we-electromagnetic uqinisekisa isikhathi sokusebenza esingaphansi kwamasekhondi angu-0.1. Isebenzisa ukufakwa kwesitimela se-DIN esijwayelekile esingu-35mm ukuze kufakwe ngokushesha,Uchungechunge lwe-RDL8-40 RCBOKusebenza kabanzi emicimbini yokuhlala, yezentengiselwano neyezimboni, ukuxazulula inkinga evamile yokukhetha yokukhubeka ngenxa yokuzwela ngokweqile kanye nezingozi zokuphepha ezifihliwe ngenxa yokungazweli ngokwanele.

Inani lokuphepha le-I-RCBO residual current breakerAkunciki kuphela ekuzweleni okuphezulu, kodwa ekuhlanganisweni kwesayensi kokufanisa isimo kanye nokuhlelwa kwamapharamitha. Ngomklamo wamapharamitha ochwepheshe, i-People Electric RDL8-40 Series inikeza ukuvikelwa kwamanje okuthembekile kwezimo ezahlukahlukene zokusetshenziswa kwamandla, okuvumela ukukhetha okunembile kanye nokusetshenziswa kwamandla okuphephile kubasebenzisi bomhlaba wonke.
