RCBO ke eng?

RCBO (Residual Current Circuit Breaker with Overcurrent Protection) ke sesebelisoa sa modular se kopanyang tšebetso ea MCB (Miniature Circuit Breaker)le RCCB (Residual Current Circuit Breaker).

Le hoja MCB e sireletsa feela lithapo hore li se ke tsa futhumala haholo (ho tlōla tekano) le ho hlōleha ha koluoa (nako e khutšoanyane), 'me RCCB e sireletsa batho feela hore ba se ke ba tšoha (ho lutla), RCBO e etsa tsohle. Haeba ho na le phoso—ebang ke ho phahama ho hoholo ha potoloho e khutšoane kapa ho lutla ho honyane ha ’mele oa motho—RCBO ea tsamaea, e arola potoloho hang-hang. Bokhoni bona bo habeli bo e etsa maemo a khauta bakeng sa lisebelisoa tsa motlakase tsa bolulo le tsa khoebo.

Mesebetsi ea mantlha le Mekhoa ea Tšireletso

RCBO ke ntho e makatsang ea miniaturization, e nang le lisebelisoa tse peli tse ikhethileng tsa ts'ireletso ka har'a casing e le 'ngoe.

Tšireletso ea Overcurrent (Karolo ea MCB):

Leeto la Mocheso: Mochini oa bimetallic oa futhumala 'me o kobeha ha o le tlas'a khatello e sa khaotseng, 'me mochine o tlangoa. Sena se sireletsa likhoele hore li se ke tsa qhibiliha.

Leeto la Magnetic: Coil ea solenoid e sebetsana le li-circuits tsa hona joale tse phahameng, e khopa se robehang ka milliseconds ho thibela ho phatloha kapa ho chesa.

Tšireletso ea Masala ea Hona Joale (Karolo ea RCCB):

Zero-Sequence Transformer: E beha leihlo boemo bo pakeng tsa Live le Neutral currents.

Ho fumanwa ha Leakage: Haeba hona joale ho lutla lefatšeng (ka mohlala, ka motho), ho se leka-lekane ho etsa hore ho be le phepelo e hlokolosi e qobellang likhokahano hore li bulehe.

Tšireletseho e Kopantsoeng: Mochine o ka hare o etselitsoe hore sisteme (ea mocheso/magnetic KAPA masalla) e khone ho kenya latch ea leeto, ho netefatsa hore ha ho phoso e sa lemoheng.

Likopo tsa mantlha le linyeoe tsa tšebeliso

Kabo ea Bolulo: Ho sireletsa li-circuits tsa motho ka mong (ka mohlala, li-sockets tsa kichine, lihitara tsa ho hlapa) moo ho hlokahalang tšireletso e ngata haholo sebakeng se lekanyelitsoeng sa phanele.

Mehaho ea Khoebo: Ho netefatsa hore litšebeletso li tsoela pele. Haeba phoso e etsahala potolohong e le 'ngoe (mohlala, PC e nang le phoso), ke RCBO feela e tsamaeang, ho e-na le matla a maholo a ho seha a RCCB mokatong oohle.

Matla a Tsosolositsoeng (Solar PV): Ho sireletsa li-circuits tsa inverter ho liphoso tsa ente tsa DC le li-overcurrents.

Taolo ea Liindasteri: Ho sireletsa li-circuits le li-motor tse hlokolosi hore li se ke tsa senyeha.

Precision Manufacturing: From Raw Material to Finished Product

Ho hlahisa RCBO ho rarahane haholo ho feta ho hlahisa MCB kapa RCCB ka thoko, kaha ho hloka khokahano e phethahetseng ea mekhoa e 'meli e fapaneng.

1. Lisebelisoa tsa mantlha:

Bolulo: Polycarbonate (PA66) ea boemo bo holimo, e thibelang malakabe (PA66) kapa Polycarbonate ho mamella mocheso o hlahisoang ke likarolo tse peli tsa tšireletso.

Mokhoa oa ho ikopanya: Silver-Tin-Oxide (AgSnO2) likhokahano tse khonang ho sebetsana le maqhubu a phahameng a nako e khuts'oane le ho lutla khafetsa.

Magnetic Core: Permalloy kapa Nanocrystalline cores bakeng sa transformer ea ho bona ha e lutla.

Yuniti ya Leeto: Kopano e rarahaneng e kopantseng sekotoana sa bimetallic, khoele ea solenoid, le polarized magnetic relay.

2. Tlhahiso le Ts'ebetso ea Ts'ebetso:

Kopano e nyane: Mochine oa MCB (thermal/magnetic) le oa RCCB (transformer/relay) li hokahantsoe meleng e arohaneng.

Kopanyo: Sistimi tsena tse peli li kopantsoe. "trip bar" e lekantsoe e le hore matla a ts'ebetso ho tsoa ho moroalo o mongata kapa ts'ebetso ea ho lutla e ka lokolla likhokahano ka katleho.

Wiring: Lihokelo tse feto-fetohang tsa ka hare li tšehelitsoe ka mokhoa o nepahetseng ho netefatsa hore ha li na matla le ho tenyetseha habonolo.

Karohano e habeli: Ena ke mohato o mahlonoko haholo. Yuniti e lekoa bakeng sa Amperage (In) (e.g., 16A) le Leakage (IΔn) (e.g., 30mA). Ka bobeli li tlameha ho lekanngoa hantle hore yuniti e fete.

Taolo e Matla ea Boleng le Maemo a Teko

Re latela IEC/EN 61009-1, maemo a machaba a li-RCBO. Teko ea rona e felile hobane sesebelisoa se jara moroalo oa mesebetsi e 'meli ea polokeho.

Lintho tse Tloaelehileng tsa Teko le Mekhoa ea Tlhahlobo ea Feme:

Ntho ea Teko	Reference Standard	Maemo a Feme ea rona le Mokhoa
Tekanyetso ea Overcurrent	E netefatsa leeto la mocheso/makenete.	E lekoa ho 1.13 Ka (ha ho leeto) le 1.45 Ka (leeto). Leeto la makenete le lekotsoe ho 3-5 In (Mofuta oa B).

Bokhoni ba rona ba Tlhahiso: Mohala, Lisebelisoa, le Sehlopha

Setsi sa rona se etselitsoe ho sebetsana le ho rarahana ha kopano ea RCBO ka nepo e phahameng.

Mohala oa Tlhahiso: Re sebelisa modular assembly lines tse re lumellang hore ho be le kopanelo ea likarolo tsa MCB le RCCB pele ho setsi sa ho qetela sa khokahanyo.

Thepa e tsoetseng pele:

Libenche tsa ho lekanya likanale tse peli: Mechini e khethehileng e lekang ka nako e le 'ngoe tekanyo ea overcurrent (Amps) le residual current rating (mA) ho netefatsa hore lisiseteme ka bobeli li sebetsa ka boikemelo le ka nepo.

Liroboto tsa ho Welding: Bakeng sa likhoele tse nepahetseng tsa kahare, ho fokotsa kotsi ea likhokahano tse hlephileng tse bohlokoa sesebelisoa se kopaneng joalo.

Lik'hamera tsa lebelo le phahameng: E sebelisoa ho R&D ho bona karohano ea likhokahano nakong ea leeto la ho ntlafatsa mokhoa oa likhokahano.

Sehlopha sa Litsebi:

Baenjineri ba Kopantsoeng: Litsebi tsa moralo oa likhokahano tsa mochini, ho netefatsa hore "trip logic" e sebetsa ntle le sekoli hore na phoso ke moroalo o mongata kapa ho lutla.

Taolo ea Boleng: E koetliselitsoe ho tseba litaba tsa "keketso ea likhathatso" le ho netefatsa hore sesebelisoa ha se na matla a motlakase a sa hlahiseng phoso.

Khetha li-RCBO tsa rona. Re fana ka sehlahisoa se fanang ka tšireletso e phahameng ka ho fetesisa sebakeng se fokolang, se etselitsoe lefatše le hlokang polokeho le katleho.
