Puas yog Switchgear zoo ib yam li tus Breaker?

Taw qhia

Thaum nws los txog rau cov khoom siv hluav taws xob, muaj ob peb nqe lus uas tuaj yeem nkag siab tsis meej. Ib lub sij hawm zoo li no yog switchgear thiab breaker. Puas yog lawv tib yam, lossis lawv txawv? Hauv tsab xov xwm no, peb yuav dhia mus rau hauv cov ntsiab lus ntawm ob qho tib si switchgear thiab breaker, thiab sib tham txog qhov zoo sib xws thiab qhov sib txawv ntawm lawv.

Dab tsi yog switchgear?

Switchgear yog ib lo lus siv los piav txog kev sib txuas ntawm cov hluav taws xob sib txuas, fuses lossis Circuit Court breakers, thiab lwm yam khoom xws li relays, busbars, thiab tswj vaj huam sib luag. Lub luag haujlwm ntawm switchgear yog los tswj thiab cais cov khoom siv hluav taws xob hauv lub network hluav taws xob.

Muaj ntau hom switchgear, nrog rau cov hluav taws xob tsis tshua muaj hluav taws xob, nruab nrab voltage switchgear, thiab high voltage switchgear. Tsawg voltage switchgear yog siv nyob rau hauv cov tsev nyob thiab kev lag luam, thaum nruab nrab thiab high voltage switchgear yog siv nyob rau hauv industrial thiab utility daim ntaub ntawv.

Switchgear yog ntsia rau hauv substations, fais fab nroj tsuag, thiab lwm yam khoom siv hluav taws xob los tiv thaiv cov khoom siv hluav taws xob thiab tiv thaiv hluav taws xob los yog ua tsis tiav. Switchgear tuaj yeem ua haujlwm manually lossis automated, thiab tuaj yeem tsim rau cov ntawv thov tshwj xeeb.

Lub breaker yog dab tsi?

Lub breaker, ntawm qhov tod tes, yog ib qho khoom siv uas tsim los cuam tshuam lossis tawg hluav taws xob thaum muaj teeb meem lossis overload tshwm sim. Breakers yog siv los tiv thaiv cov khoom siv hluav taws xob los ntawm kev puas tsuaj thiab tiv thaiv hluav taws xob.

Lub breaker tuaj yeem yog cov cuab yeej siv tshuab, xws li fuse lossis Circuit Court breaker, lossis nws tuaj yeem yog software-based system, zoo li digital tiv thaiv relay. Breakers yog siv rau hauv vaj tse, kev lag luam, thiab kev lag luam kev lag luam, thiab yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ncaj ncees ntawm cov khoom siv hluav taws xob.

Muaj ntau hom breakers, xws li thermal breakers, magnetic breakers, thiab hydraulic-magnetic breakers. Txhua hom breaker muaj nws tus kheej cov yam ntxwv thiab kev siv.

Zoo sib xws ntawm switchgear thiab breaker

Thaum switchgear thiab breaker yog cov ntsiab lus sib txawv, muaj qhov sib xws ntawm ob. Ob lub switchgear thiab breaker yog siv los tiv thaiv cov khoom siv hluav taws xob, tiv thaiv hluav taws xob, thiab xyuas kom muaj kev nyab xeeb thiab kev ncaj ncees ntawm cov khoom siv hluav taws xob.

Switchgear thiab breaker tuaj yeem tsim los rau cov kev siv tshwj xeeb, thiab ob qho tib si yog cov khoom tseem ceeb ntawm lub tshuab hluav taws xob. Switchgear thiab breaker tuaj yeem ua haujlwm manually lossis automated, thiab tuaj yeem ua ke nrog lwm yam khoom siv hluav taws xob rau kev ua haujlwm tsis sib haum.

Qhov sib txawv ntawm switchgear thiab breaker

Thaum switchgear thiab breaker sib piv, kuj muaj qhov sib txawv ntawm ob. Thawj qhov sib txawv ntawm switchgear thiab breaker yog tias switchgear yog kev sib xyaw ntawm cov khoom hluav taws xob, thaum lub tshuab hluav taws xob yog ib qho cuab yeej tsim los cuam tshuam cov hluav taws xob hluav taws xob.

Switchgear yog tsim los tswj thiab cais cov khoom siv hluav taws xob hauv lub network hluav taws xob, thaum lub tshuab hluav taws xob tsim los cuam tshuam lossis tawg hluav taws xob hluav taws xob thaum muaj teeb meem lossis overload tshwm sim. Switchgear tuaj yeem tsim rau cov ntawv thov qis, nruab nrab, lossis siab voltage, thaum lub tshuab hluav taws xob feem ntau tsim los rau cov qib voltage tshwj xeeb.

Switchgear tuaj yeem ua haujlwm manually lossis automated, thaum breakers feem ntau automated thiab koom nrog kev tiv thaiv relays thiab tswj cov tshuab. Switchgear tuaj yeem tsim los muab lub zog thaub qab thiab rov ua dua, thaum lub tshuab tawg yog tsim los tiv thaiv cov khoom siv hluav taws xob los ntawm kev puas tsuaj thiab tiv thaiv hluav taws xob.

Xaus

Hauv kev xaus, switchgear thiab breaker yog ob yam tseem ceeb ntawm lub tshuab hluav taws xob. Thaum switchgear yog ib qho kev sib xyaw ntawm cov khoom siv hluav taws xob tsim los tswj thiab cais cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob, lub tshuab hluav taws xob yog ib qho cuab yeej tsim los cuam tshuam lossis tawg hluav taws xob hluav taws xob thaum muaj teeb meem lossis overload tshwm sim.

Switchgear thiab breaker muaj qhov sib xws, suav nrog lawv siv los tiv thaiv cov khoom siv hluav taws xob, tiv thaiv hluav taws xob, thiab ua kom muaj kev nyab xeeb thiab kev ncaj ncees ntawm cov khoom siv hluav taws xob. Txawm li cas los xij, lawv kuj txawv ntawm lawv cov haujlwm tseem ceeb, kev siv, thiab kev tsim qauv. Kev nkag siab qhov sib txawv ntawm switchgear thiab breaker tuaj yeem pab xyuas kom muaj kev xaiv thiab kev ua haujlwm ntawm cov khoom tseem ceeb no hauv lub tshuab hluav taws xob.
