Koj puas paub Dab tsi yog Circuit Breakers?

Dab tsi yog Circuit Breakers?

Ib qho hluav taws xob hloov hluav taws xob tsim los tiv thaiv hluav taws xob hluav taws xob tiv thaiv kev puas tsuaj uas tshwm sim los ntawm kev dhau tam sim no / overload lossis luv luv Circuit Court hu ua Circuit Court breaker.Nws lub luag haujlwm tseem ceeb yog cuam tshuam tam sim no ow tom qab kev tiv thaiv relays pom muaj teeb meem.

Kev ua haujlwm ntawm Circuit Breaker Hloov.

Lub Circuit Court breaker muaj nuj nqi los ntawm kev ua cov cuab yeej kev nyab xeeb yog li tiv thaiv kev puas tsuaj rau lub cev muaj zog thiab cov xaim hluav taws xob thaum tam sim no ntws los ntawm cov hluav taws xob hluav taws xob hloov pauv nws cov kev txwv tsim.Nws ua qhov no los ntawm kev tshem tawm tam sim no los ntawm lub voj voog thaum muaj xwm txheej tsis zoo tshwm sim.

DC Circuit Breakers ua haujlwm li cas?

Raws li lawv lub npe qhia, Direct Current (DC) Circuit Court breakers tiv thaiv cov khoom siv hluav taws xob uas ua haujlwm ntawm qhov hluav taws xob ncaj qha.Qhov tseem ceeb ntawm qhov sib txawv ntawm qhov ncaj qha tam sim no thiab hloov tam sim no yog tias qhov hluav taws xob tawm hauv DC yog tas li.Nyob rau hauv sib piv, qhov voltage tso zis nyob rau hauv Alternating Current (AC) cycles ob peb zaug ib ob.

Lub luag haujlwm ntawm DC Circuit Breaker yog dab tsi?

Tib yam kev tiv thaiv thermal thiab sib nqus siv rau DC breakers raws li lawv ua rau AC Circuit Court breakers:
Kev tiv thaiv cua sov tawm mus rau DC Circuit Court breaker thaum hluav taws xob tam sim no tshaj tus nqi ntsuas.Bimetallic contact heats nthuav dav thiab mus ncig lub Circuit Court breaker nyob rau hauv no tiv thaiv mechanism.Kev tiv thaiv thermal ua haujlwm sai dua vim tias qhov tam sim no tsim cov cua sov kom nthuav dav thiab qhib qhov hluav taws xob sib txuas raws li qhov tam sim no tseem ceeb heev.Lub DC Circuit Court breaker lub thermal tiv thaiv tiv thaiv lub overload tam sim no uas yog me ntsis siab dua qhov kev khiav hauj lwm tam sim no.
Thaum muaj qhov tsis zoo tam sim no, kev tiv thaiv kev sib nqus mus rau DC Circuit Court breaker, thiab cov lus teb yog ib txwm instantaneous.Zoo li AC Circuit Court breakers, DC Circuit Court breakers muaj lub peev xwm tawg uas sawv cev rau qhov tseem ceeb tshaj plaws tam sim no uas tuaj yeem cuam tshuam.
Qhov tseeb tias qhov tam sim no raug tso tseg tsis tu ncua nrog DC Circuit Court breakers txhais tau hais tias lub Circuit Court breaker yuav tsum qhib qhov hluav taws xob tiv tauj deb kom cuam tshuam qhov txhaum tam sim no.Lub DC Circuit Court breaker cov hlau nplaum tiv thaiv tiv thaiv luv luv Circuit Court thiab faults ntau tshaj li qhov overload.

Peb hom Miniature Circuit Breaker:

Hom B (kev mus ncig ntawm 3-5 zaug ntsuas tam sim no).
Hom C (kev mus ncig ntawm 5-10 lub sijhawm ntsuas tam sim no).
Hom D (kev mus ncig ntawm 10-20 lub sijhawm ntsuas tam sim no).
