Kev Tshawb Fawb tob tob rau hauv Residual Current Operated Circuit Breaker (RCBO)

Hauv cov tshuab hluav taws xob niaj hnub no, kev nyab xeeb thiab kev ntseeg siab yog qhov tseem ceeb tshaj plaws.Cov Khoom Siv Hluav Taws Xob Uas Ua Haujlwm Tam Sim No (RCBO) yog ib lub cuab yeej tiv thaiv tseem ceeb uas tsim los tiv thaiv kev phom sij ntawm hluav taws xob xws li kev poob hluav taws xob thiab hluav taws kub los ntawm kev ua txhaum hluav taws xob. Los ntawm kev sib txuas ua ke ntawm kev tiv thaiv overload, luv luv, thiab kev tiv thaiv tam sim no, RCBO muab kev nyab xeeb rau ntau yam kev siv. Hauv tsab xov xwm no, peb yuav tshawb nrhiav cov yam ntxwv tseem ceeb thiab cov lus qhia txog kev siv RCBO thiab lawv lub luag haujlwm hauv kev tiv thaiv cov kab ke hluav taws xob.

Lub luag haujlwm tseem ceeb ntawm RCBO

RCBO muaj ntau txoj kev tiv thaiv ua ke hauv ib lub cuab yeej. Lawv lub luag haujlwm tseem ceeb yog nrhiav pom qhov overloads, luv circuits, lossis residual currents (leakage currents) thiab txiav tawm lub hwj chim tam sim ntawd kom tiv thaiv kev puas tsuaj rau tib neeg thiab khoom vaj khoom tsev. Qhov no ua rau RCBOs muaj ntau yam siv tau, vim lawv siv tau rau ntau qhov chaw, txij li kev teeb tsa hauv tsev mus rau kev lag luam thiab kev lag luam.

Cov Lus Qhia Tseem Ceeb thiab Cov Nta

1. Qhov Ntsuas Tam Sim No: RCBOs muaj ntau yam kev xaiv tam sim no kom haum rau ntau yam kev siv. Cov qauv feem ntau xws li CMTB1LE-32 thiab CMTB1LE-63 npog qhov ntsuas tam sim no txij li 3A txog 63A. Tshwj xeeb, CMTB1LE-32 muaj nyob rau hauv qhov ntsuas ntawm 3A, 6A, 10A, 16A, 20A, 25A, thiab 32A, ua rau nws zoo tagnrho rau cov xwm txheej thauj khoom me me mus rau nruab nrab. CMTB1LE-63, ntawm qhov tod tes, yog tsim los rau cov khoom thauj siab dua, nrog qhov ntsuas tam sim no ntawm 40A, 50A, thiab 63A, zoo meej rau cov ntawv thov muaj zog siab dua.

2. Lub Peev Xwm Tua Hluav Taws Xob Luv: RCBO tau tsim los kom tiv thaiv kev ntws ntawm cov hluav taws xob yog tias muaj hluav taws xob luv. Tus qauv CMTB1LE-32 muaj peev xwm tua hluav taws xob ntawm 6000A, uas ua kom muaj kev txiav tawm sai thaum muaj hluav taws xob ntau dhau. CMTB1LE-63 muab cov peev xwm tua hluav taws xob sib txawv nyob ntawm qhov ntsuas tam sim no: 6000A ntawm 40A thiab 4500A ntawm 50A thiab 63A. Cov peev xwm ruaj khov no ua rau RCBO txhim khu kev qha hauv kev tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob thaum muaj teeb meem.

3. Kev Teeb Tsa Ncej: RCBO muaj kev ywj pheej nrog kev teeb tsa ncej, suav nrog 1P + N, 2P, 3P + N, thiab 4P kev xaiv, ua rau lawv hloov tau rau ob qho tib si ib theem thiab peb theem hluav taws xob. Qhov kev hloov pauv no tso cai rau ntau yam kev siv thaum ua kom ntseeg tau tias cov circuits raug tiv thaiv los ntawm kev overload, luv luv circuits, thiab cov dej ntws seem.

4. Hom Kev Tiv Thaiv Cov Hluav Taws Xob seem: Muaj ob hom kev tiv thaiv cov hluav taws xob seem uas RCBO muab—Hom C thiab Hom D, tsim los rau cov hluav taws xob ntsuas ntawm 3A thiab 63A. Hom C yog tsim rau cov khoom thauj txheem, thaum Hom D yog tsim los rau cov khoom thauj siab lossis capacitive, xws li cov cav lossis cov khoom siv hauv kev lag luam. Qhov no tso cai rau RCBO los tswj ntau hom kev thauj khoom zoo, tiv thaiv kev thauj khoom ntau dhau lossis kev puas tsuaj.

5. Kev rhiab heev ntawm cov hluav taws xob seem: RCBOs muaj ntau qib kev rhiab heev rau cov hluav taws xob seem, uas yog qhov tseem ceeb rau kev tiv thaiv kev xau. Cov hluav taws xob seem ua haujlwm (IΔn) feem ntau muaj cov kev xaiv xws li 30mA, 50mA, thiab 100mA, kom ntseeg tau tias lub cuab yeej tuaj yeem ntes cov hluav taws xob xau thiab txiav lub zog yog tias xav tau. Tsis tas li ntawd, cov hluav taws xob seem tsis ua haujlwm (IΔno) xaiv ntawm 15mA, 25mA, thiab 50mA muab kev meej ntxiv hauv kev tiv thaiv kev tripping tsis xav tau thaum tswj kev nyab xeeb.

6. Lub Sijhawm Teb Sai: Thaum pom muaj qhov teeb meem hluav taws xob, RCBOs teb yuav luag tam sim ntawd, nrog lub sijhawm tripping tsawg dua 0.1 vib nas this. Qhov kev teb sai no txo ​​qhov kev pheej hmoo ntawm kev puas tsuaj loj lossis xwm txheej, muab kev tiv thaiv txhim khu kev qha rau ntau hom hluav taws xob sib txawv.

Cov Ntawv Thov RCBO

RCBOs siv dav hauv cov tsev nyob, cov lag luam, thiab cov chaw faib hluav taws xob qis. Lawv cov yam ntxwv tiv thaiv ua rau lawv tsis tseem ceeb rau cov chaw siv hluav taws xob niaj hnub no, qhov twg muaj ntau yam khoom thauj thiab nyuaj.

Rau cov kev siv hauv tsev, RCBO xyuas kom meej tias cov khoom siv hluav taws xob hauv tsev raug tiv thaiv los ntawm cov hluav taws xob xau, tiv thaiv kev phom sij ntawm hluav taws xob. Hauv cov chaw lag luam, RCBO tiv thaiv cov khoom siv tseem ceeb thiab cov khoom siv hauv paus los ntawm kev ua txhaum hluav taws xob, xyuas kom meej tias kev lag luam txuas ntxiv mus. Hauv cov ntawv thov kev lag luam, tshwj xeeb tshaj yog qhov twg cov khoom siv xws li lub cev muaj zog thiab cov tshuab hnyav siv, Hom D RCBO muab kev tiv thaiv zoo tshaj plaws tiv thaiv cov hluav taws xob siab uas tuaj yeem tshwm sim nrog cov khoom siv inductive zoo li no.
