Hauv cov tshuab hluav taws xob thiab ntau yam kev siv hluav taws xob, cov hluav taws xob hluav taws xob, ua cov khoom siv tiv thaiv tseem ceeb, dais lub luag haujlwm tseem ceeb ntawm kev cuam tshuam cov dej tsis zoo thiab tiv thaiv kev ua txhaum loj.Lawv yog "thawj kab ntawm kev tiv thaiv" kom ntseeg tau tias kev ruaj ntseg ntawm daim phiaj thiab kev nyab xeeb ntawm qhov kawg - cov neeg siv hluav taws xob.
Functionally, lub Circuit Court breaker yog ib qho kev hloov khoom siv uas tuaj yeem kuaj xyuas cov xwm txheej hauv Circuit Court thiab ua haujlwm qhib thiab kaw. Thaum muaj qhov txaus ntshai tam sim no tshwm sim hauv Circuit Court vim muaj qhov txawv txav xws li luv luv Circuit Court, overloads, los yog undervoltage, nws ua tau - nyob rau hauv tripping mechanism teb sai heev, txiav tawm Circuit Court nyob rau hauv milliseconds los tiv thaiv kev puas tsuaj thib ob xws li cov khoom burnout thiab kab hluav taws. Nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, nws muaj peev xwm ntseeg tau nqa load tam sim no, kom ntseeg tau ib tug tas mus li fais fab mov. Qhov "kev txiav txim siab ntse + kev txiav txim sai" tus yam ntxwv ua rau nws siv dav hauv qis-voltage fais fab kev faib tawm, kev tswj lub cev muaj zog, tsim hluav taws xob thiab kev faib tawm, thiab txawm tias lub zog hluav taws xob tshiab.
Los ntawm kev hloov pauv thev naus laus zis, kev ua haujlwm ntawm cov hluav taws xob hluav taws xob tau txuas ntxiv tawg los ntawm kev txwv. Cov tsoos hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob, tso siab rau cov txiaj ntsig thermal ntawm tam sim no rau kev ua, tau hloov los ntawm cov khoom siv hluav taws xob ntau dua los yog cov tshuab ntse. Cov tom kawg siv cov sensors los saib xyuas ntau yam tsis xws li tam sim no thiab qhov hluav taws xob hauv lub sijhawm tiag tiag, sib txuas cov algorithms kom ua tiav qib kev tiv thaiv. Qhov no tsis tsuas yog tiv thaiv kev ua haujlwm tsis zoo los ntawm kev cuam tshuam cov khoom siv hluav taws xob txuas ntxiv tab sis kuj raug cais tawm cov kev pheej hmoo hauv cov xwm txheej nyuaj. Tsis tas li ntawd, lawv cov qauv me me thiab cov qauv tsim ua rau lawv yooj yim rau kev sib koom ua ke rau hauv cov khoom siv hluav taws xob sib txuas, thaum lawv cov peev txheej siab (piv txwv li, siab dua 100kA) ua tau raws li qhov siab - muaj peev xwm, siab - hloov pauv kev xav tau ntawm cov phiaj xwm niaj hnub no.
Raws li "tus neeg saib xyuas kev nyab xeeb" ntawm lub zog hluav taws xob, kev ntseeg siab ntawm cov hluav taws xob hluav taws xob ncaj qha cuam tshuam rau qhov zoo ntawm hluav taws xob siv hauv kev tsim khoom thiab kev ua neej nyob txhua hnub. Nrog rau kev nce qib ntawm "dual-}carbon" cov hom phiaj thiab kev tsim kho cov tshuab hluav taws xob tshiab, lawv qhov kev hloov pauv mus rau DC qhov xwm txheej thiab siab -frequency harmonic ib puag ncig txuas ntxiv txhim kho, thiab lawv tab tom tso lub hauv paus ruaj ntseg rau kev hloov pauv hluav taws xob nrog txoj hauv kev ntse dua thiab muaj zog.
