2. Kev Ruaj Ntseg Siab: Hom B RCCBs yog tsim los nrog kev ruaj ntseg siab, feem ntau ntsuas ntawm 30 mA rau kev tiv thaiv tus kheej thiab 300 mA rau kev tiv thaiv cov khoom siv. Qhov kev ruaj ntseg no yog qhov tseem ceeb rau kev tiv thaiv kev poob hluav taws xob thiab txo qhov kev pheej hmoo ntawm hluav taws xob hluav taws xob.

3. Kev Siv Dav Dav: Cov RCCBs no tsis yog tsuas yog siv rau hauv tsev xwb tab sis kuj tsim nyog rau kev siv rau kev lag luam thiab kev lag luam. Lawv lub peev xwm los tswj cov hluav taws xob DC ua rau lawv zoo tagnrho rau cov tsheb fais fab, cov roj teeb khaws cia lub zog, thiab lwm yam khoom siv DC.

4. Cov Qauv Ua Raws Li**: Hom B RCCBs ua raws li cov qauv kev nyab xeeb thoob ntiaj teb, xyuas kom meej tias lawv ua tau raws li qhov yuav tsum tau ua rau kev teeb tsa hluav taws xob. Qhov kev ua raws li no yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov kab ke hluav taws xob.

Cov txiaj ntsig ntawm kev siv Hom B RCCB

1. Kev Nyab Xeeb Zoo Dua: Qhov txiaj ntsig tseem ceeb ntawm kev siv lub tshuab hluav taws xob seem hom B (RCCB) yog kev nyab xeeb zoo dua uas nws muab. Los ntawm kev ntes cov hluav taws xob AC thiab DC xau, cov khoom siv no txo ​​qhov kev pheej hmoo ntawm kev raug hluav taws xob thiab hluav taws xob, tiv thaiv lub neej thiab khoom vaj khoom tsev.

2. Kev Tiv Thaiv Cov Khoom Siv Rhiab: Hauv cov chaw uas siv cov khoom siv hluav taws xob rhiab heev, xws li cov chaw khaws ntaub ntawv lossis cov chaw kuaj mob, Hom B RCCBs muab kev tiv thaiv ntxiv. Lawv pab tiv thaiv kev puas tsuaj rau cov khoom siv los ntawm kev ua txhaum hluav taws xob, ua kom ntseeg tau tias kev ua haujlwm tsis tu ncua.

3. Kev Koom Tes Nrog Cov Txheej Txheem Zog Rov Ua Dua Tshiab: Thaum lub ntiaj teb hloov mus rau lub zog rov ua dua tshiab, qhov kev xav tau rau Hom B residual current circuit breakers tab tom loj hlob. Muaj peev xwm tswj tau cov hluav taws xob ncaj qha, Hom B residual current circuit breakers yog qhov tseem ceeb rau cov txheej txheem photovoltaic hnub ci thiab lwm yam kev siv hluav taws xob rov ua dua tshiab, pab kom muaj kev nyab xeeb koom ua ke cov thev naus laus zis no rau hauv lub grid.

4. Kev daws teeb meem uas pheej yig: Txawm hais tias tus nqi pib ntawm Hom B RCCB yuav siab dua li tus qauv RCCB, nws lub peev xwm los muab kev tiv thaiv dav dav tuaj yeem ua rau txuag tau nyiaj mus sij hawm ntev. Los ntawm kev tiv thaiv kev puas tsuaj ntawm hluav taws xob thiab kev puas tsuaj uas yuav tshwm sim, Hom B RCCB tuaj yeem txo cov nqi kho thiab ua kom koj lub tshuab hluav taws xob siv tau ntev.

Hauv luv luv

Hauv kev xaus lus, Hom B residual current circuit breakers (RCCBs) yog ib qho tseem ceeb ntawm cov txheej txheem kev nyab xeeb hluav taws xob niaj hnub no. Lawv lub peev xwm tshwj xeeb los ntes ob qho tib si AC thiab DC leakage currents ua rau lawv muaj txiaj ntsig zoo rau ntau yam kev siv, tshwj xeeb tshaj yog hauv kev lag luam hluav taws xob rov ua dua tshiab. Los ntawm kev nqis peev rau Hom B residual current circuit breaker (RCCB), cov tib neeg thiab cov lag luam tuaj yeem txhim kho kev nyab xeeb, tiv thaiv cov khoom siv rhiab heev, thiab xyuas kom ua raws li cov qauv hluav taws xob. Thaum thev naus laus zis txuas ntxiv mus, qhov tseem ceeb ntawm Hom B residual current circuit breakers (RCCBs) hauv kev tiv thaiv cov khoom siv hluav taws xob yuav txuas ntxiv mus.
