China Wopereka Zotsalira Zotsalira Pakalipano Zophwanyika Ndi Chitetezo Chowonjezera

SankhaniCDADAmonga wopanga ndi wopereka. Kuchokera ku China, timapereka Residual Current Circuit Breaker ndi Chitetezo cha Overcurrent, komanso zida zina zambiri zamagetsi zotsika kwambiri. Titha kupanga mayankho aukadaulo, osinthidwa ogwirizana ndi zomwe mukufuna; katundu wathu amabwera ndi chitsimikizo cha zaka 3 ndipo amatsatira mfundo zosiyanasiyana zapadziko lonse lapansi.

Kodi RCBO ndi chiyani?

An RCBO (Residual Current Circuit Breaker with Overcurrent Protection) ndi chipangizo chomwe chimaphatikiza magwiridwe antchito a MCB (Miniature Circuit Breaker)ndi RCCB (Residual Current Circuit Breaker).

Ngakhale MCB imateteza zingwe kuti zisatenthedwe (kuchulukira) komanso kulephera kowopsa (chifupifupi), ndipo RCCB imateteza anthu kuti asagwedezeke (kutuluka), RCBO imachita zonse. Cholakwika chikachitika - kaya ndikuthamanga kwakukulu kuchokera kudera lalifupi kapena kudontha pang'ono kudzera mthupi la munthu - RCBO imayenda, ndikupatula dera nthawi yomweyo. Kuthekera kwapawiri kumeneku kumapangitsa kuti ikhale muyezo wagolide pazoyika zamakono zogona komanso zamalonda.

Mitundu ndi Magulu

Maluso athu opangira RCBO amaphatikiza masinthidwe osiyanasiyana aukadaulo kuti akwaniritse zofuna za msika wapadziko lonse lapansi.

Ntchito Zazikulu ndi Njira Zotetezera

RCBO ndi yodabwitsa ya miniaturization, yokhala ndi zida ziwiri zodzitchinjiriza mkati mwa casing imodzi.

Chitetezo Chowonjezera (Chigawo cha MCB):

Ulendo Wotentha: Mzere wa bimetallic umatenthedwa ndikupindika ndikuchulukana, ndikutsegula makinawo. Izi zimateteza zingwe kuti zisasungunuke.

Maginito Ulendo: Koyilo ya solenoid imagwira ntchito ikafika patali pang'ono, imapunthwa chophwanyira pama milliseconds kuteteza kuphulika kapena moto.

Chitetezo Chotsalira Pano (Chigawo cha RCCB):

Zero-Sequence Transformer: Imayang'anira mosalekeza kuchuluka kwa mafunde a Live ndi Neutral.

Kutulukira kwa Leakage: Ngati madzi akutsikira padziko (monga kudzera mwa munthu), kusalinganikako kumayambitsa chingwe cholumikizira chomwe chimakakamiza olumikizanawo kutsegula.

Chitetezo Chophatikizana: Makina amkati adapangidwa kuti dongosolo liwonse (thermal/magnetic OR residual) liziyambitsa latch yapaulendo, kuwonetsetsa kuti palibe cholakwika chilichonse.

Zofunikira Zoyambira ndi Zogwiritsa Ntchito

Kugawa Nyumba Zogona: Kuteteza ma circuits pawokha (monga soketi zakukhitchini, zotenthetsera m'bafa) komwe kumafunika chitetezo chambiri komanso kugwedezeka kwapanelo.

Nyumba Zamalonda: Kuonetsetsa kuti ntchito zikuyenda. Ngati cholakwika chichitika pa dera limodzi (mwachitsanzo, PC yolakwika), RCBO yokhayo ndiyomwe imayenda, osati mphamvu yayikulu yodulira ya RCCB pansi.

Mphamvu Zowonjezeranso (Solar PV): Kuteteza ma circuit inverter ku zolakwika za jakisoni wa DC ndi ma overcurrents.

Industrial Control: Kuteteza ma circuit ndi ma motors tcheru ku zolakwika za gawo-to-ground.

Kupanga Mwachindunji: Kuchokera Zopangira Zopangira Mpaka Kumaliza Zogulitsa

Kupanga RCBO ndikovuta kwambiri kuposa kupanga MCB kapena RCCB padera, chifukwa pamafunika kulumikizana kwabwino kwa njira ziwiri zosiyana.

1. Zida Zazikulu:

Nyumba: High grade, flame-retardant Polyamide (PA66) kapena Polycarbonate kuti zipirire kutentha kopangidwa ndi zinthu ziwiri zoteteza.

Contact System: Silver-Tin-Oxide (AgSnO2) malumikizana nawo omwe amatha kunyamula mafunde afupiafupi komanso kuthawitsa pafupipafupi.

Magnetic Core: Permalloy kapena Nanocrystalline cores za thiransifoma yozindikira kuti yatuluka.

Gawo la Ulendo: Zophatikiza zovuta kuphatikiza mzere wa bimetallic, nsolenoid coil, ndi polarized magnetic relay.

2. Kupanga & Kukonza Kayendetsedwe ka Ntchito:

Sub-Assembly: Makina a MCB (matenthedwe/maginito) ndi makina a RCCB (transformer/relay) amalumikizidwa pamizere yosiyana.

Kuphatikiza: Makina awiriwa aphatikizidwa. "trip bar" imawunikidwa kuti mphamvu yamakina yochokera pakuchulukira kapena kuzindikira kwatsikirako athe kumasula zolumikizana.

Wiring: Zolumikizira zotha kusinthasintha zamkati zimawoleredwa mwatsatanetsatane kuti zitsimikizire kulimba kochepera komanso kusinthasintha kwamakina.

Pawiri Calibration: Ili ndiye sitepe yovuta kwambiri. Chigawochi chimayesedwa Amperage (In) (monga 16A) ndi Leakage (IΔn) (monga 30mA). Zonsezi ziyenera kuyesedwa bwino kuti unit idutse.

Kuwongolera Kwabwino Kwambiri ndi Miyezo Yoyesera

Timatsatira IEC/EN 61009-1, muyezo wapadziko lonse wa ma RCBO. Kuyezetsa kwathu ndikokwanira chifukwa chipangizochi chimanyamula katundu wa ntchito ziwiri zotetezera.

Zinthu Zoyeserera Zokhazikika & Zoyendera Pafakitale:

Mphamvu Zathu Zopanga: Mzere, Zida, ndi Gulu

Malo athu adapangidwa kuti azitha kuthana ndi zovuta za msonkhano wa RCBO molondola kwambiri.

Production Line: Timagwiritsa ntchito mizere ya ma module yomwe imalola kuphatikizika kwa zigawo za MCB ndi RCCB malo ophatikizana asanafike.

Zida Zapamwamba:

Mabenchi Oyimilira Awiri-Channel: Makina apadera omwe amayesa nthawi imodzi ma overcurrent rating (Amps) ndi residual current rating (mA) pofuna kuonetsetsa kuti makina onsewa akugwira ntchito modziimira komanso moyenera.

Maloboti Owotcherera Odzichitira: Pa mawaya olondola amkati, kuchepetsa chiopsezo cha maulumikizidwe otayirira omwe ndi ofunikira mu chipangizo chophatikizika chotere.

Makamera Othamanga Kwambiri: Zogwiritsidwa ntchito mu R&D kuti ziwone kusiyana kwa olumikizana paulendo kuti muwongolere njira yolumikizirana.

Gulu la Katswiri:

Kuphatikiza Engineers: Akatswiri pamakina olumikizirana, kuwonetsetsa kuti "trip logic" imagwira ntchito mosalakwitsa ngakhale cholakwikacho ndi chochulukira kapena kutayikira.

Kuwongolera Ubwino: Wophunzitsidwa kuzindikira zovuta za "zosokoneza" ndikuwonetsetsa kuti chipangizocho sichikhudzidwa ndi ma volteji omwe siwolakwika.

Sankhani ma RCBO athu. Timapereka mankhwala omwe amapereka chitetezo chokwanira m'malo ochepa, opangidwira dziko lapansi omwe amafunikira chitetezo komanso kuchita bwino.
