Residual Current Circuit Breaker Factory Direct Nqe

CDADAtau tsim nyob rau xyoo 2004, txawm tias peb lub hauv paus pib rov qab mus rau xyoo 1980s. Kos raws li kaum xyoo ntawm kev txawj ntse tshwj xeeb, peb tau hloov zuj zus mus rau hauv cov neeg paub tab thiab cov kws tshaj lij cov chaw tsim khoom thiab cov chaw muag khoom ntawm Residual Current Circuit Breakers. Peb caw koj los koom tes nrog peb kom tau txais txiaj ntsig los ntawm cov kev pabcuam kev txhawb nqa kev ntseeg siab thiab tus nqi ncaj qha los ntawm lub Hoobkas.

Residual Current Circuit Breaker (RCCB) yog dab tsi?

RCCB yog ib qho khoom siv hluav taws xob tshwj xeeb kev nyab xeeb tsim los txiav tawm lub voj voog thaum twg nws pom qhov tsis sib xws tam sim no ntawm cov nyob (theem) thiab cov neeg nruab nrab nruab nrab. Qhov kev tsis txaus ntseeg no, hu ua qhov seem tam sim no lossis cov dej ntws tawm, qhia tau hais tias hluav taws xob tau ntws los ntawm txoj kev tsis xav tau - muaj peev xwm los ntawm tib neeg lub cev lossis cov rwb thaiv tsev tsis zoo.

Tsis zoo li ibMCBlos yogMCCB, RCCB tsis muab kev tiv thaiv overload lossis luv-circuit tiv thaiv ntawm nws tus kheej (tshwj tsis yog ua ke nrog lawv hauv RCBO). Nws lub hom phiaj ib leeg yog kev nyab xeeb lub neej thiab kev tiv thaiv hluav taws. Nws ua haujlwm raws li Kirchhoff Txoj Cai Tam Sim No, qhov twg cov txiaj ntsig ntawm cov dej ntws nkag mus rau hauv kev sib tshuam yuav tsum sib npaug ntawm cov dej ntws tawm. Yog hais tias qhov "hauv" thiab "tawm" tam sim no sib txawv los ntawm ntau tshaj li ntawm cov cuab yeej rhiab heev (piv txwv li, 30mA), RCCB mus ncig ua si.

Hom thiab Classifications

Peb qhov chaw tsim khoom lag luam npog ntau yam ntawm RCCB hom kom haum rau ntau qhov chaw hluav taws xob, los ntawm ib-theem tsev mus rau txoj kev lag luam peb-theem.

Hom	Ncej / Configuration	Cov yam ntxwv tseem ceeb	Daim ntawv thov

Core Functions thiab Intelligent Protection

Lub plawv ntawm peb RCCB yog Zero-Sequence Tam Sim No Transformer (Toroid). Cov khoom no tsis tu ncua saib xyuas cov magnetic teb uas tsim los ntawm cov dej ntws tam sim no.

Kev kuaj pom dej: Raws li cov xwm txheej ib txwm muaj, cov chaw sib nqus ntawm Live thiab nruab nrab tam sim no tshem tawm ib leeg. Yog tias txoj kev xau mus rau lub ntiaj teb tshwm sim (piv txwv li, ib tus neeg kov cov hlau nyob), qhov sib npaug yuav tawg.

Ceev Disconnection: Lub transformer kuaj pom qhov "cov seem" flux thiab induces ib tug voltage nyob rau hauv nws ob peb winding. Cov teeb liab no yog amplified (hauv hom hluav taws xob) los yog ncaj qha actuates ib tug rhiab relay (nyob rau hauv electromagnetic hom), ua rau lub tshuab latch tso tawm thiab qhib cov neeg.

Sensitivity Ratings:

Siab rhiab heev (10mA - 30mA): Rau kev tiv thaiv ncaj qha (tib neeg kev nyab xeeb). Yuav tsum tau rau chav dej, qhov (socket), thiab sab nraum zoov circuits.

Nruab nrab rhiab heev (100mA - 300mA): Rau kev tiv thaiv kev tiv thaiv thiab tiv thaiv hluav taws. Siv nyob rau hauv lub ntsiab faib boards los tiv thaiv cables los ntawm rwb thaiv tsev faults.

Cov ntawv thov tseem ceeb thiab siv rooj plaub

Kev Nyab Xeeb Hauv Chaw Nyob: Yuav tsum tau teeb tsa hauv chav dej, chav ua noj, thiab qhov hluav taws xob sab nraum zoov kom tsis txhob muaj kev puas tsuaj los ntawm cov khoom siv xws li cov tshuab plaub hau lossis cov cuab yeej hluav taws xob.

Muaj Machinery: Tiv thaiv cov neeg ua haujlwm los ntawm hluav taws xob poob thaum tuav cov khoom siv hlau los yog cov cuab yeej nqa tau yooj yim.

Cov Chaw Kho Mob: Ua kom cov neeg mob muaj kev nyab xeeb hauv tsev kho mob qhov twg txawm tias cov dej ntws me me tuaj yeem ua rau tuag taus (siv hom B lossis tshwj xeeb kev kho mob IT systems).

Renewable Zog: Tiv thaiv DC thiab AC sab ntawm lub hnub ci PV systems thiab EV them chaw nres tsheb los ntawm av txhaum.

Precision Manufacturing: Los ntawm raw khoom mus rau cov khoom tiav

Peb cov txheej txheem ntau lawm yog ib lub suab ntawm precision magnetics thiab mechanical engineering.

1. Cov Khoom Siv Tseem Ceeb:

Zero-Sequence Transformer Core: Ua los ntawm high-permeability Permalloy (Nickel-Iron alloy) los yog Nanocrystalline strips. Cov khoom siv no yog qhov tseem ceeb rau kev kuaj xyuas cov dej ntws tawm hauv feeb yam tsis muaj saturation.

Trip Relay / Solenoid: Ib tug rhiab heev polarized relay uas hloov lub teeb liab hluav taws xob los ntawm lub transformer mus rau hauv txhua yam txav.

Tsev: Nplaim-retardant Polycarbonate (PC) los yog Nylon (PA66), tsim los ua kom tsis muaj hluav taws xob thiab cuam tshuam.

Tiv tauj: Silver-Cadmium-Oxide (AgCdO) los yog Silver-Nickel (AgNi) rau kev hloov pauv tau zoo thiab tsis muaj zog.

2. Kev Tsim Khoom & Kev Ua Haujlwm Ua Haujlwm:

Toroid Winding: Lub precision transformer core yog mob nrog ntau txhiab lem ntawm ultra-zoo tooj liab hlau. Qhov no yuav tsum tau ua nrog kev saib xyuas hnyav kom tsis txhob ua kom luv luv.

Core Encapsulation: Cov tub ntxhais sib nqus yog encapsulated hauv epoxy resin los tiv thaiv nws ntawm kev co thiab av noo, ua kom muaj kev ruaj ntseg ntev.

Kev sib dhos: Lub toroid muab tso rau ib ncig ntawm tus neeg xyuas pib txoj kev (los yog tus neeg xyuas pib hla nws). Cov txheej txheem mus txawv tebchaws yog txuas nrog lub ntsiab kev sib cuag latch.

Calibration (Sensitivity Setting): Nov yog kauj ruam tseem ceeb tshaj plaws. Peb siv cov peev txheej tam sim no los txhaj cov xau tam sim no (piv txwv li, 30mA). Cov kauj ruam mus txawv tebchaws yog kho kho kom haum kom txog thaum nws ua haujlwm raws nraim ntawm qhov pib.

Rigorous Quality Control thiab Test Standards

Peb ua raws li IEC / EN 62423 thiab IEC / EN 61008 tus qauv. Peb qhov kev sim ntsuas yog tsim los xyuas kom meej tias cov cuab yeej mus ncig tsuas yog thaum nws yuav tsum, thiab ib txwm thaum nws yuav tsum.

Standard Test Yam khoom & Lub Hoobkas Kev Ntsuam Xyuas Cov Cai:
