Ua ntej, qhov pib qhia ntawm high-voltage switchgear
Raws li lub npe qhia, high-voltage switchgear yog cov khoom siv hluav taws xob faib hluav taws xob siv hauv cov khoom siv hluav taws xob rau hluav taws xob faib hluav taws xob, tswj, ntsuas thiab txuas cov cables.
Cov khoom siv hluav taws xob tsawg tsawg yog nyob rau hauv lub vaj huam sib luag, tswj lub thawv, hloov lub thawv ntawm txhua qhov hluav taws xob, uas yog cov khoom siv uas ua tau raws li cov qauv tsim los ntawm kev sib sau ua ke qee cov khoom siv tiv thaiv xws li keyboards, Circuit Court breakers, fuses, nyees khawm, taw qhia teeb, cov twj paj nruag, xov hlau, thiab lwm yam. Feem ntau hu ua: siab thiab tsis tshua muaj hluav taws xob hloov hluav taws xob lossis hluav taws xob siab thiab qis hluav taws xob ua tiav cov khoom siv.
Qhov thib ob, lub luag haujlwm ntawm txhua lub txee faib khoom
High-voltage inlet txee, metering txee, high-voltage qhov hluav taws xob txee, low-voltage inlet txee, capacitor txee, low-voltage qhov hluav taws xob txee, cov tis txee yog cov pa configuration ntawm chav faib, tsis hais txog ntawm high voltage los yog tsawg voltage. ua ke raws li ib qho kev ua haujlwm.
(1) High-voltage incoming txee: Nws yog ib lub txee high-voltage uas tawg lub siab-voltage cov khoom siv hluav taws xob, qhov tseeb, nws tsis yog lub txee tuaj tiag tiag, thiab cov kab tuaj feem ntau tsis txuas nrog lub txee no, tab sis yog txuas nrog lub txee cais, tab sis nws muaj lub tshuab hluav taws xob (lub tshuab nqus tsev) txhawm rau txhawm rau cov khoom siv hluav taws xob, yog li nws yog hu ua lub txee nkag.
(2) Metering txee: Raws li lub npe qhia, nws yog siv los txhim kho lub watt-teev meter, ntsuas qhov tseeb npaum li cas koj siv hluav taws xob, lub txee tsis muaj cov khoom loj tshwj tsis yog PT thiab CT.
(3) high-voltage qhov hluav taws xob txee: nws lub luag hauj lwm yog siv los faib thiab xa hluav taws xob hluav taws xob, nws feem ntau nqa transformers los yog high-voltage hluav taws xob khoom (lub cev muaj zog) thiab high-voltage them nyiaj
(4) Tsawg-voltage inlet txee: - Feem ntau yog ib lub txee los ntawm lub transformer, tseem hu ua lub qis lub ntsiab txee, siv los tswj tag nrho cov khoom siv hluav taws xob hauv qab no, nws lub ntsiab hloov feem ntau yog siv lub thav duab Circuit Court breaker.
(5) Capacitor txee: nws lub luag hauj lwm yog los them nyiaj rau qhov zoo ntawm hluav taws xob thiab txhim kho lub hwj chim zoo!
(6) Tsawg-voltage qhov hluav taws xob txee: nws lub luag hauj lwm yog siv los faib thiab xa hluav taws xob hluav taws xob, nws txawv ntawm high-voltage yog pib ncaj qha mus rau cov khoom siv hluav taws xob, qhov hloov feem ntau yog siv cov molded case Circuit Court breaker.
