Hnub ci DC lsolator Hloov, WTIS (rau lub thawv sib txuas)

Lus piav qhia luv luv:

WTIS hnub ci DC rho tawm hloov yog ib qho cuab yeej siv nyob rau hauv photovoltaic (PV) systems los cais DC input los ntawm lub hnub ci vaj huam sib luag. Nws feem ntau yog ntsia rau hauv lub thawv sib txuas, uas yog lub thawv sib txuas uas txuas ntau lub hnub ci vaj huam sib luag ua ke.
DC rho tawm hloov pauv tuaj yeem cuam tshuam DC fais fab mov thaum muaj xwm txheej ceev lossis kev saib xyuas, ua kom muaj kev nyab xeeb ntawm lub tshuab hluav taws xob photovoltaic. Nws yog tsim los tswj qhov siab DC voltage thiab tam sim no tsim los ntawm cov hnub ci vaj huam sib luag.
Lub luag haujlwm ntawm lub hnub ci DC rho tawm keyboards suav nrog:
Huab cua tiv taus thiab ruaj khov qauv: Qhov hloov yog tsim rau kev teeb tsa sab nraum zoov thiab tuaj yeem tiv taus huab cua hnyav.
Bipolar hloov: Nws muaj ob tug ncej thiab muaj peev xwm ib txhij disconnect qhov zoo thiab tsis zoo DC circuits, kom ntseeg tau tias tag nrho kev sib cais ntawm lub system.
Lockable kov: Lub qhov hloov pauv yuav muaj lub qhov rooj xauv los tiv thaiv kev nkag mus tsis raug cai lossis ua haujlwm tsis raug.
Pom pom qhov taw qhia: Qee cov keyboards muaj lub teeb pom kev pom uas qhia txog cov xwm txheej ntawm qhov hloov pauv (on / off).
Ua raws li cov qauv kev nyab xeeb: Kev hloov pauv yuav tsum ua raws li cov qauv kev nyab xeeb, xws li IEC 60947-3, txhawm rau ua kom muaj kev nyab xeeb.
