1, Kev qhia yooj yim ntawm high-voltage switchgear
High voltage switchgear, raws li lub npe qhia, yog ib tug tis khoom siv nyob rau hauv lub hwj chim mov system rau lub zog faib, tswj, metering, thiab txuas cables. Feem ntau, cov khoom siv hluav taws xob thiab cov chaw siv hluav taws xob siv hluav taws xob hloov hluav taws xob siab, uas txuas nrog rau cov khoom siv hluav taws xob tsawg tsawg los ntawm cov hluav taws xob qis sab hneev ntawm lub transformer.
Cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob yog cov khoom siv uas sib sau ua ke tiv thaiv cov khoom siv xws li cov keyboards, Circuit Court breakers, fuses, nyees khawm, taw qhia teeb, ntsuas, thiab cov xov hlau kom tau raws li cov qauv tsim ua haujlwm hauv ntau lub zog faib vaj huam sib luag, tswj lub thawv, thiab hloov lub thawv. Feem ntau hu ua: high thiab low voltage switchgear los yog high thiab low voltage hluav taws xob cov khoom tiav.
2, Lub luag haujlwm ntawm txhua lub txee faib khoom
High voltage incoming txee, metering txee, high voltage outgoing txee, low voltage incoming txee, capacitor txee, thiab low voltage outgoing txee yog cov pa configurations ntawm chav faib, thiab ob qho tib si high thiab tsawg voltage yog ua ke raws li tej yam kev ua.
(1) High voltage incoming txee: Nws yog ib tug high voltage txee uas disconnects lub high voltage nkag fais fab mov. Nws tsis yog lub txee tuaj, thiab cov kab tuaj feem ntau tsis txuas nrog lub txee no, tab sis mus rau lub txee cais. Txawm li cas los xij, nws muaj lub tshuab hluav taws xob hluav taws xob (lub tshuab nqus tsev) uas tuaj yeem cuam tshuam cov khoom siv hluav taws xob tuaj, yog li nws hu ua lub txee nkag.
(2) Ntsuas ntsuas: Raws li lub npe qhia, nws yog lub txee siv los nruab cov ntsuas hluav taws xob thiab ntsuas qhov tseeb tias koj siv hluav taws xob ntau npaum li cas. Lub txee no tsis muaj cov khoom loj tshwj tsis yog PT thiab CT.
(3) High voltage outgoing txee: Nws txoj haujlwm yog xa tawm thiab xa hluav taws xob hluav taws xob. Nws feem ntau nqa transformers, high-voltage hluav taws xob khoom (lub cev muaj zog), thiab high-voltage them nyiaj, thiab lwm yam
(4) Tsis tshua muaj hluav taws xob nkag hauv txee: Feem ntau, nws yog lub txee uas los ntawm lub tshuab hluav taws xob, tseem hu ua lub txee qis, siv los tswj tag nrho cov khoom siv hluav taws xob hauv qab no. Nws lub ntsiab hloov yog feem ntau yog ib tug ncej Circuit Court breaker.
(5) Capacitor txee: Nws txoj haujlwm yog los them rau lub zog zoo thiab txhim kho lub zog!
(6) Tsis tshua muaj hluav taws xob tawm txee: Nws txoj haujlwm yog faib thiab xa hluav taws xob hluav taws xob. Tsis zoo li qhov hluav taws xob siab, nws yog qhov yooj yim txuas ncaj qha rau cov khoom siv hluav taws xob, thiab qhov hloov pauv feem ntau yog siv cov ntaub ntawv molded Circuit Court breaker.
