Dab tsi yog qhov sib txawv ntawm qhov seem tam sim no Circuit Court breaker thiab ib qho hluav taws xob tsis tu ncua?

Qhov tseem ceeb sib txawv ntawm aresidual tam sim no Circuit Court breaker (RCCB)thiab atsis tu ncua Circuit Court breakeryog tias ib qho kev tiv thaiv hluav taws xob tsis tu ncua tiv thaiv kab thiab khoom siv, thaum RCCB feem ntau tiv thaiv tus kheej kev nyab xeeb.

Lawv cov haujlwm tseem ceeb sib txawv

Ordinary circuit breakers feem ntau saib xyuas qhov loj ntawm qhov tam sim no, tiv thaiv cov xov hlau thiab cov khoom siv hluav taws xob los ntawm overheating thiab burning vim tam sim no ntau dhau, overload, los yog luv luv Circuit Court, yog li tiv thaiv hluav taws.

Qhov seem tam sim no Circuit Court breakers (RCCBs) feem ntau saib xyuas qhov sib npaug tam sim no, tiv thaiv tus kheej kev nyab xeeb los ntawm hluav taws xob poob vim los ntawm kev puas tsuaj los ntawm cov rwb thaiv tsev hauv cov xov hlau lossis cov khoom siv.

Cov ntsiab cai ua haujlwm thiab cov qauv sib txawv

1. Txheem Circuit Breaker

Txoj Cai: Saib xyuas qhov loj tam sim no. Thaum qhov tam sim no tshaj qhov ntsuas tus nqi, cov cuab yeej siv tshuab sab hauv (bimetallic strip / electromagnetic coil) mus ncig.

Structure: Feem ntau muaj cov kev hloov pauv thiab cov khoom siv tiv thaiv ob qho no, tsuas yog tsom mus rau tag nrho cov tam sim no ntawm cov hlau nyob (thiab cov xaim nruab nrab).

Key Parameter: Rated tam sim no

Cov Cim Cim Cim: Feem ntau tsuas yog qhov hloov pauv thiab qhov ntsuas tam sim no tau tshwm sim.

2. Residual Current Circuit Breaker (RCCB)

Txoj Cai: Saib xyuas qhov nyiaj tshuav tam sim no. Ib txhij kuaj xyuas qhov tam sim no hauv cov xov hlau nyob thiab nruab nrab; thaum qhov sib txawv ntawm ob (tam sim no ntws) mus txog tus nqi txaus ntshai, nws tawm mus sai sai.

Structure: tuaj yeem nkag siab tias yog ntxiv qhov ntsuas qhov ntsuas qhov ntsuas tam sim no rau cov qauv ntsuas hluav taws xob. Yog li ntawd, qee qhov RCCBs kuj muaj ntau dhau thiab luv luv -cov haujlwm tiv thaiv hluav taws xob (cov khoom no feem ntau hu ua RCBO).

Cov ntsiab lus tseem ceeb: ntsuas tam sim no + to tam sim no tripping tam sim no

Cov Cim Cim Cim: suav nrog lub pob xeem (yuav tsum nias txhua hli) thiab lub pob pib dua, feem ntau cim "30mA".

Sib txawv Application Scenario

1. Standard Circuit Breaker: Siv raws li kev tiv thaiv yooj yim rau tag nrho cov circuits, xws li lub ntsiab keyboards, teeb pom kev zoo circuits, thiab siab rau cua txias circuits.

Feem ntau tiv thaiv cov hluav taws kub nyhiab tshwm sim los ntawm kev laus txoj hlua, cov khoom siv tsis ua haujlwm, thiab kev xaim tsis zoo.

2. Residual Current Circuit Breaker (RCCB): Siv rau lub davhlau ya nyob twg Circuit Court uas ncaj qha lossis ncaj qha rau tib neeg lub cev, xws li txhua lub qhov hluav taws xob (tshwj xeeb tshaj yog nyob rau hauv qhov chaw ntub dej xws li chav ua noj, chav dej, thiab lub sam thiaj), cov khoom siv tes tuav, thiab cov khoom siv txawb.

Residual tam sim no Circuit Court breakers (RCCBs) yog tsim los tiv thaiv kev tuag hluav taws xob thiab tiv thaiv tus kheej kev nyab xeeb. Cov pa hluav taws xob hluav taws xob (CCBs), ntawm qhov tod tes, muab kev tiv thaiv yooj yim tiv thaiv hluav taws los ntawm kev ua txhaum hauv Circuit Court. Kev xaiv kom raug thiab teeb tsa ntawm ob qho tib si tseem ceeb heev rau kev tsim kom muaj kev nyab xeeb hluav taws xob.
