Intengo Eqondile Yefektri Yamanje Ye-Curcuit Breaker Residual

I-I-CDADAyasungulwa ngo-2004, nakuba imvelaphi yethu isukela kuma-1980s. Ngokusebenzisa amashumi eminyaka ochwepheshe obukhethekile, siguqukele ekubeni umkhiqizi ovuthiwe nochwepheshe kanye nomphakeli wama-Residual Current Circuit Breakers. Sikumema ukuba ubambisane nathi ukuze uzuze ezinhlelweni zosekelo lobuchwepheshe ezithembekile kanye namanani asuka embonini.

Yini I-Residual Current Circuit Breaker (RCCB)?

I RCCB iyisisetshenziswa esikhethekile sokuphepha sikagesi esiklanyelwe ukunqamula isekethe noma nini lapho ithola ukungalingani kwamanje phakathi kwamakhondaktha abukhoma (isigaba) kanye nama-neutral. Lokhu kungalingani, okwaziwa ngokuthi i-residual current noma leakage current, kubonisa ukuthi ugesi ugeleza ngendlela engahlosiwe—okungenzeka ukuthi udlula emzimbeni womuntu noma ukuwohloka kokufakwa kwamanzi.

Ngokungafani ne-I-I-MCBnomaI-I-MCCB, i-RCCB ayikunikezi ukugcwala ngokweqile noma ukuvikelwa kwesiyingi esifushane ngokwayo (ngaphandle kwalapho kuhlanganiswe nakho ku-RCBO). Inhloso yawo ukuphepha kwempilo nokuvikela umlilo. Isebenza ngokususelwe Kumthetho Wamanje We-Kirchhoff, lapho isamba sama-currents angena empambanweni kufanele ilingane nesamba sama-currents ayishiyayo. Uma ama-currents "in" kanye "out" ehluka ngaphezu kokuzwela kwedivayisi (isb., 30mA), i-RCCB iyahamba.

Izinhlobo Nezigaba

Iphothifoliyo yethu yokukhiqiza ihlanganisa izinhlobonhlobo zezinhlobo ze-RCCB ukuze zivumelane nezimo ezihlukahlukene zikagesi, kusukela ezindlini zesigaba esisodwa kuya kumagridi ezimboni ayinkimbinkimbi ezigaba ezintathu.

Uhlobo	Izigxobo / Ukucushwa	Izici Eziyinhloko	Uhlelo lokusebenza olujwayelekile
Thayipha i-AC	I-2-Pole (1P+N) / 4-Pole (3P+N)	Ithola imisinga eyinsalela ye-AC ye-sinusoidal.	Amasekhethi okukhanya/amandla avamile okuhlala kanye nokuhweba.
Uhlobo A	2-Isigxobo / 4-Isigxobo	Ithola i-AC kanye namaza asalayo e-DC.	Izifunda ezinemithwalo ye-elekthronikhi (imishini yokuwasha, amakhompyutha, ama-dimmers).
Uhlobo F	2-Isigxobo / 4-Isigxobo	Ithola i-AC, i-pulsating DC, nama-multi-frequency currents ayinhlanganisela.	Amasekhethi akhethekile anamadrayivu esivinini aguquguqukayo (VSD) nezinto zikagesi zeClass I.
Uhlobo B	4-Isigxobo	Ithola wonke amaza ohlobo lwe-A/F kanye nama-DC abushelelezi.	Iziteshi zokushaja ze-EV zezigaba ezintathu, iziguquli zelanga, kanye nemishini yezokwelapha.

Imisebenzi Esemqoka Nokuvikelwa Okukhaliphile

Inhliziyo ye-RCCB yethu i-Zero-Sequence Current Transformer (Toroid). Le ngxenye ngokuqhubekayo iqapha inkambu kazibuthe ekhiqizwa ukugeleza kwamanje.

Ukutholwa kokuvuza: Ngaphansi kwezimo ezijwayelekile, izinkundla kazibuthe zama-Live and Neutral currents ziyakhansela. Uma indlela yokuvuza eya emhlabeni yenzeka (isb., umuntu uthinta intambo ephilayo), ibhalansi iphukile.

Ukunqanyulwa Okusheshayo: I-transformer ithola lokhu kuguquguquka "okusele" bese idala i-voltage ekujikeni kwayo kwesibili. Le signali iyakhuliswa (ngezinhlobo zama-elekthronikhi) noma isebenze ngokuqondile i-relay ezwelayo (ezinhlotsheni ze-electromagnetic), okubangela ukuthi i-latch yomshini ikhulule futhi ivule abathintwayo.

Izilinganiso Zokuzwela:

Ukuzwela Okuphezulu (10mA - 30mA): Ngokuvikela othintana naye ngokuqondile (ukuphepha komuntu). Kuyimpoqo kumagumbi okugezela, amasokhethi, namasekhethi angaphandle.

Ukuzwela Okumaphakathi (100mA - 300mA): Ngokuvikela ukuthintana okungaqondile nokuvikela umlilo. Isetshenziswa kumabhodi okusabalalisa amakhulu ukuze kuvikelwe izintambo emaphutheni e-insulation.

Izicelo Eziyinhloko Nezimo Zokusebenzisa

Ukuphepha Kwendawo yokuhlala: Ukufakwa okuyisibopho ezindlini zangasese, emakhishini, nasezindaweni ezingaphandle ukuze kuvinjelwe ukushaqeka okubulalayo okuvela ezintweni zikagesi ezifana nezomisa izinwele noma amathuluzi kagesi.

Imishini Yezimboni: Ukuvikela ama-opharetha ekushayweni kukagesi lapho ephethe impahla yensimbi noma amathuluzi aphathekayo.

Izinsiza Zokunakekelwa Kwezempilo: Ukuqinisekisa ukuphepha kwesiguli ezibhedlela lapho ngisho nokuvuza okuncane kungabulala (kusetshenziswa Uhlobo B noma amasistimu e-IT ezokwelapha akhethekile).

Amandla Avuselelekayo: Ukuvikela izinhlangothi ze-DC ne-AC zamasistimu e-solar PV kanye neziteshi zokushaja ze-EV kumaphutha asemhlabeni.

Ukukhiqiza Okunembayo: Kusuka ku-Raw Material kuya kuMkhiqizo Oqediwe

Inqubo yethu yokukhiqiza iyi-symphony yokunemba kazibuthe nobunjiniyela bemishini.

1. Izinto Ezisetshenziswa Kakhulu:

I-I-Zero-Sequence Transformer Core: Yenziwe nge-high-permeability Permalloy (i-Nickel-Iron alloy) noma ama-Nanocrystalline strips. Lokhu okubalulekile kubalulekile ukuze kutholwe ukuvuza kwamaminithi okuvuza ngaphandle kokugcwaliswa kwesikhala.

I-I-Trip Relay/Solenoid: I-relay e-polarized ezwela kakhulu eguqula isignali kagesi isuke ku-transformer ibe ukunyakaza kokusebenza.

Izindlu: I-Flame-retardant Polycarbonate (PC) noma Nylon (PA66), edizayinelwe ukuthi ingaqhubeki futhi imelane nomthelela.

Oxhumana nabo: I-Silver-Cadmium-Oxide (AgCdO) noma I-Silver-Nickel (AgNi) yokushintsha okuthembekile nokumelana okuphansi.

2. Ukukhiqiza Nokucubungula Ukuhamba komsebenzi:

I-I-Toroid Winding: I-precision transformer core inezinkulungwane zokujika kwentambo yethusi ecwebe kakhulu. Lokhu kumele kwenziwe ngokucophelela okukhulu ukuze kugwenywe ukufinyeza amajika.

I-I-Core Encapsulation: I-magnetic core ifakwe ku-epoxy resin ukuze ivikeleke ekudlidlizeni nasekuswakeni, okuqinisekisa ukuzinza kwesikhathi eside.

Umhlangano: I-toroid ibekwe eduze kwendlela kakhondatha (noma amakhondatha adlula kuyo). Indlela yohambo ixhunywe ku-latch yokuxhumana eyinhloko.

Ukulinganisa (Ukusetha Ukuzwela): Lesi isinyathelo esibucayi kakhulu. Sisebenzisa imithombo yamanje enembayo ukujova amandla avuzayo (isb., 30mA). Ikhoyili yohambo ilungiswa ngomshini ize isebenze ncamashi embundwini.

Ukulawulwa Kwekhwalithi Eqinile kanye Namazinga Okuhlola

Sithobela izindinganiso ze-IEC/EN 62423 kanye ne-IEC/EN 61008 . Umbuso wethu wokuhlola uklanyelwe ukuqinisekisa ukuthi idivayisi ihamba kuphela uma kufanele, futhi njalo lapho kufanele.

Izinto Ezijwayelekile Zokuhlola Nemibandela Yokuhlola Imboni:

Into yokuhlola	Isithenjwa Esijwayelekile	I-Factory Standard & Indlela yethu

Isikhathi Sokubambezeleka Test	Iqinisekisa isivinini sokusebenza.	Jova 5 x IΔn (isb., 150mA). Idivayisi kufanele ihambe ngo < 40ms (Uhlobo Oluvamile) noma phakathi nesikhathi esishiwo soHlobo S (Olukhethiwe).
Amandla e-Dielectric	Iqinisekisa ukuhlukaniswa.	Kusetshenziswe 2000V AC iminithi elingu-1 phakathi kwamatheminali okokufaka/okukhiphayo kanye nozimele. Akukho ukwehlukana.
Operation Mechanical	Iqinisekisa ukuqina kwe-latch.	Imijikelezo engu-2,000 yokusebenza YOKUVULA/KUVALE ngaphandle kokwehluleka.
I-Short-Circuit Withstand	Iqinisekisa amandla okusinda.	I-RCCB kufanele imelane ne-short-circuit current (isb., 3kA noma 6kA) ngaphandle kokuqhuma noma ukubamba umlilo (okuqinisekiswa ngokuvikelwa kwe-fuse).

Amakhono Ethu Okukhiqiza: Ulayini, Izisetshenziswa, kanye Nethimba

Isikhungo sethu sihlonyiselwe ukuphatha imvelo ethambile yezingxenye zokuzwa kazibuthe.

Ulayini Wokukhiqiza: Sisebenzisa imishini yokufaka umoya ye-toroidal ezenzakalelayo eqinisekisa ukubala okungaguquguquki nokushuba, okubalulekile ukuzwa kwamanje okunembile.

Okokusebenza Okuthuthukile:

Ukuvuza Okunembile Izikali Zamanje: Amathuluzi anembe kakhulu akwazi ukukhiqiza ukuvuza kwamanzi anokulungiswa okungu-0.1mA ukuze kulungiswe kahle izilungiselelo zohambo.
