Dab tsi yog qhov hloov pauv cais?Dab tsi yog qhov kev ua haujlwm ntawm kev cais tawm?Yuav xaiv li cas?
Qhov kev sib cais cais txhua tus tau hais txog yog ib qho nrog lub rooj vag machete me me qhib.Disconnect lub switching fais fab mov zoo.Nyob rau hauv high voltage, qhov kev rho tawm yuav tsum tsis txhob loaded.Kev thauj mus los ntawm qhov rub-hauv qhov hloov yuav ua rau hluav taws xob tsis sib haum xeeb, kub hnyiab me me, thiab muaj kev puas tsuaj loj rau lub neej.
Lub isolator yog siv ua ke nrog lub Circuit Court breaker nyob rau hauv siab ua hauj lwm siab.Thaum kho txoj kev, qhib thiab tua lub zog ua ntej kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm tu.
Cov khoom siv hluav taws xob cais tawm, ib qho hloov pauv hauv ntiaj teb, ob chav earthing hloov, tsheb npav khi hloov hauv 11kv substation.Nruab nrab grounding hloov.
Kev ntsuas qhov tseeb ntawm qhov hluav taws xob siab ua kom pom tseeb tias ib qho kev hloov pauv hauv av txhais tau hais tias thaum lub qhov hloov tau raug kaw, ib sab ntawm txoj kev yog hauv av kom muaj kev nyab xeeb.Ib yam yog muaj tseeb rau ob chav grounding hloov.Nyob rau hauv tag nrho cov txheej txheem ntawm kev kaw lub hwj chim, lub busbar tuaj yeem hloov tawm lub zog kom muaj kev ua haujlwm ntawm kev hloov hluav taws xob, thiab qhov nruab nrab hauv av hloov pauv yog qhov hloov pauv rau kev ua haujlwm.
Lub luag haujlwm tseem ceeb ntawm kev cais tawm yog raws li hauv qab no.
1. Thaum ua tiav kev saib xyuas cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob, siv qhov kev sib cais los cais cov khoom siv hluav taws xob thiab cov khoom tsis muaj hluav taws xob, tsim kom muaj qhov cuam tshuam kev cuam tshuam, cais kev saib xyuas ntawm cov khoom siv los ntawm cov khoom siv hluav taws xob loj tam sim no. , thiab xyuas kom muaj kev ruaj ntseg ntawm cov neeg ua haujlwm thiab cov khoom siv hluav taws xob faib khoom.
2. Cov kev hloov pauv thiab cov hluav taws xob hluav taws xob sib koom ua ke los hloov txoj haujlwm thiab hloov txoj kev ua haujlwm.
①Thaum lub Circuit Court breaker ntawm cov khoom tawm ntawm ib pawg ntawm cov chav tsev raug kaw vim lwm yam laj thawj, thaum lub bypass Circuit Court breaker siv rau lwm yam haujlwm, ib qho kev rho tawm tuaj yeem raug xaiv thiab txuas nrog cov tswj Circuit Court;
②Rau ib nrab-kaw thaiv, thaum lub voj voog luv luv hauv ib lub koob tsim cov kais dej, ib qho kev sib cais tuaj yeem siv los kho lub voj voog (tab sis nco ntsoov tias tag nrho cov kab hluav taws xob hauv lwm cov koob yuav tsum nyob rau hauv txoj hauj lwm rov qab);
③A ob txoj kev tsheb thauj mus los ib ntu txuas txoj kev.Thaum ib qho ntawm ob lub tsheb thauj mus los thiab cov segmented Circuit Court breaker raug kaw, nws tuaj yeem raug txiav tawm raws li qhov hloov pauv.
Kev faib tawm ntawm cov hluav taws xob rho tawm hluav taws xob.
Los ntawm txoj kev khiav hauj lwm ntawm cov hluav taws xob rwb thaiv tsev keyboards, cov khoom siv hluav taws xob cais cov keyboards tuaj yeem muab faib ua kab rov tav rotating, ntsug rotating, plug-in thiab lwm yam khoom siv hluav taws xob cais cov keyboards.Raws li tus naj npawb ntawm cov hluav taws xob hluav taws xob hloov hluav taws xob, hluav taws xob hluav taws xob hloov hluav taws xob tuaj yeem muab faib ua ib kem, ib-kem, thiab peb-kem hluav taws xob rho tawm hluav taws xob hloov.
Qhov tseeb, qhov no kuj yog ib hom kev hloov khoom siv, uas tuaj yeem txuas nrog lossis txiav tawm los ntawm kev hloov hluav taws xob.Tsuas yog qee qhov tseem ceeb me me ntawm kev hloov hluav taws xob cais tawm.Piv txwv li, thaum lub tshuab hluav taws xob cais tawm tau muab faib ua ntu, muaj qhov qhia meej meej ntawm qhov kev ncua deb ntawm cov kab hluav taws xob hauv nruab nrab ntawm Circuit Court breaker, thiab nws kuj muaj cov cim tseem ceeb ntawm kev sib txuas.Thaum cov hluav taws xob rho tawm hluav taws xob raug kaw, qhov hluav taws xob rho tawm hluav taws xob tuaj yeem dais tag nrho cov tam sim no nyob rau hauv ib txwm tswj loops thiab txawv txav tshwm sim, xws li luv luv-circuit faults nyob rau hauv cov ntaub ntawv ntawm short-circuit faults nyob rau hauv tus txheej txheem heev.
Xaiv txoj kev kaw lub hwj chim thiab kaw.Thaum lub hwj chim tawm, ua ntej disconnect lub Circuit Court breaker thiab cia lub hwj chim Circuit Court disconnect lub load.Yog hais tias tsis muaj load, disconnect tus rho tawm.Thaum xaim, xyuas seb lub load Circuit Court breaker puas raug txiav lawm., Tsuas yog thaum tag nrho cov load-sab Circuit Court breakers nyob rau hauv qhov kev tshwm sim, uas yog, thaum lub disconnecting keyboards raug kaw thiab tsis muaj load, nws yuav rov qab tau.Tom qab lub disconnecting hloov yog muab tua, lub Circuit Court breaker yuav raug kaw dua.
