Ntaub thaiv npog: kev cais tawm

Txhua yam khoom siv uas txuas mus rau lub hwjchim daim phiaj yuav tsum tau txais kev pabcuam los ntawm cov switchboards. Cov kev ua ub no nqa tawm nyob rau hauv raws li cov kev cov ntaub ntawv, raws li zoo raws li lub SAE.

Lub rooj sib txoos ntawm cov hluav taws xob panels yog qhov kawg ntawm lub installation cov hauj lwm, uas tsis yog lub installation ntawm cov ntaub thaiv npog nws tus kheej xwb, tab sis kuj nws equipping nrog cov tsim nyog "stuffing". Feem ntau muaj cov teem tawm lub mov kab ntawm lub cev, raws li zoo raws li lub automatic ntsiab ntawm kev tswj. Ntaub thaiv npog hluav taws xob yuav tsum sawv cev raws li ib tug hauv zos tswj tsev uas tej zaum yuav muaj xws li sib txawv hwj chim relays, Circuit Court tej fais fab, av log tsheb thiab vanishing, thiab ntau yam kev tswj hais.

Cov ntawv cog lus hluav taws xob muaj qee yam tshwj xeeb. Yog li, cais:

- Hloov zog.

- Cov teeb pom kev zoo.

- Kev tawm tswv yim thiab kev faib khoom thiab khoom siv.

- Shields rau kev ntsuas hluav taws xob.

- Cov ntsiab lus faib.

- Cov thawv, lub thoob, cov log tsheb, thiab lwm yam.

Kev lig kev cai, hluav taws xob shield tiav nrog txhua yam xav tau ntawm cov nroj tsuag, qhov chaw tshwj xeeb yog nruab. Qhov zoo thiab kev ntseeg ntawm cov khoom yuav tsum ua raws li high requirements, thiab yog li ntawd ncaj qha nyob ntawm qhov tseeb thiab raug ntawm installation.

Lub ntsiab faib khoom faib tawm (MDF) yog ib qho khoom siv uas muaj cov khoom siv rau kev npaj hluav taws xob. Qhov no ntaus ntawv yog dav siv nyob rau hauv pej xeem, chaw ua hauj lwm thiab tej vaj tse thiab tej chaw, raws li zoo raws li nyob rau hauv industrial cov nroj tsuag thiab substations. Lub xov tooj tseem ceeb yog tsim los faib hluav taws xob thoob plaws hauv lub tsev, nrog rau kev tiv thaiv tawm tsam tshaj thiab luv circuits ntawm sab hauv thiab sab nraud. Ib qho hluav taws xob ntawm hom no kuj ua tau ntau yam dej num ntsig txog kev tiv thaiv thaum muaj xwm ceev fais fab tuag, thaum nws yog ib qho tsim nyog yuav tau hloov lub hwj huam mus rau txoj kev cia siab.

VRUs yog siv los txais thiab xa hluav taws xob hluav taws xob. Hauv qhov no, kev faib khoom nruab nrab ntawm cov neeg txais kev pab yog nqa tawm, thiab kev tiv thaiv ntawm kev sib ceg tiv thaiv luv luv circuits thiab overloads. Tiv thaiv hluav taws xob hom ASU yog npaj los muab tsis ntau ua hauj lwm rau hauv thiab tawm mov chains. Rau nws qhov kev tso kawm nws yog ib qhov tsim nyog yuav tau nruab ib chav tsev tshwj xeeb, nyob ncaj nraim rau hauv qhov chaw nruab nrab ntawm cov nyiaj.

Tsis Siv Neeg tawm tswv yim (ATS) yog siv rau lub hwj chim rov qab los ntawm attaching lub receivers backup hwj chim qhov twg los rau-off lub sij hawm ua hauj lwm, raws li zoo raws li rau reclosing ua hauj lwm mov qhov twg los. Cov cuab yeej no tau ua nyob thoob plaws hauv cov tes hauj lwm uas muaj vaj tse, cov khw thiab cov lag luam, nrog rau kev sib txuas lus thiab kev sib txuas lus kom ua tau raws li qhov yuav tsum tau muaj kev cia siab ntawm cov khoom hluav taws xob.

Thaum tsim tus vaj huam sib luag rau yav tom ntej, nws yog qhov tsim nyog kom paub qhov tseeb pes tsawg txuas. Qhov no ua hauj lwm pab los mus txiav txim qhov ntev ntawm lub apparatus, thiab lub hom thiab tus naj npawb ntawm kev tiv thaiv pab kiag li lawm thiab tswj nyob rau ntawd.
