Cov kab hluav taws xob qis qis yog hais txog cov kab uas txo cov high-voltage 10KV mus rau 380/220v theem los ntawm kev faib transformer, uas yog, cov kab uas tsis tshua muaj hluav taws xob xa tawm los ntawm lub substation mus rau cov khoom siv.

Cov kab hluav taws xob qis qis yuav tsum tau txiav txim siab thaum tsim txoj kev xaim ntawm lub substation.Rau qee qhov kev cob qhia nrog kev siv hluav taws xob loj, lub rooj cob qhia kuj tau nruab nrog lub tshuab hluav taws xob substation.Lub transformer muab lub zog rau cov khoom siv hluav taws xob, thaum lub rooj cob qhia uas siv hluav taws xob tsawg, cov khoom siv hluav taws xob ncaj qha los ntawm kev faib khoom transformer.

Tsawg-voltage fais fab faib txoj kev

Cov kab hluav taws xob tsis tshua muaj hluav taws xob yog tsim thiab tso tawm raws li hom, qhov loj me, kev faib tawm thiab qhov xwm txheej ntawm cov khoom thauj.Feem ntau, muaj ob hom kev faib tawm, hom radial thiab pob tw, raws li pom hauv daim duab ntawm sab xis.

Radial kab muaj kev ntseeg tau zoo, tab sis cov nqi peev siab, yog li tam sim no qhov hluav taws xob qis hluav taws xob xaim hluav taws xob feem ntau yog siv lub cev, uas tuaj yeem tau txais kev hloov pauv txaus.Thaum cov khoom siv thev naus laus zis hloov pauv, cov kab xa tawm tsis tas yuav tsum muaj kev hloov pauv loj.Tus nqi hluav taws xob kuj tsawg, uas yog nws ob yam tseem ceeb.Ntawm chav kawm, nyob rau hauv cov nqe lus ntawm kev ntseeg siab ntawm lub hwj chim mov, nws tsis zoo li lub radial hom.

Hom ntawm cov kab hluav taws xob tsawg tsawg

Muaj ob txoj kev teeb tsa rau cov kab hluav taws xob qis, uas yog, txoj kev tso kab hluav taws xob thiab cov txheej txheem nyiaj siv ua haujlwm.

Vim tias cov kab hluav taws xob tau muab tso rau hauv av, nws muaj kev cuam tshuam me ntsis rau lub ntiaj teb sab nraud, xws li cua daj cua dub thiab dej khov, thiab tsis muaj cov xov hlau raug rau hauv av, yog li beautifying lub nroog zoo li thiab ib puag ncig ntawm lub tsev, tab sis tus nqi peev. ntawm cov kab hluav taws xob yog siab, thiab kev saib xyuas yog qhov nyuaj dua., qhov zoo ntawm cov kab nyiaj siv ua haujlwm tsuas yog qhov sib txawv.Yog li ntawd, rau qhov chaw uas tsis muaj qhov tshwj xeeb, cov xaim hluav taws xob tsawg siv cov txheej txheem nyiaj siv ua haujlwm.

Cov kab hluav taws xob qis qis feem ntau yog ua los ntawm cov ncej ntoo lossis cov cement ncej los ua cov xov tooj, thiab cov fwj porcelain yog siv los kho cov xov hlau ntawm tus ntoo khaub lig ntawm tus ncej.Qhov kev ncua deb ntawm ob tug ncej yog li ntawm 30 ~ 40M hauv lub tshav puam, thiab nws tuaj yeem ncav cuag 40 ~ 50M hauv thaj chaw qhib.Qhov kev ncua deb ntawm cov xaim yog 40 ~ 60 cm.Lub erection ntawm txoj kab yog luv li sai tau.Yooj yim rau tu thiab kho.

Distribution box ntawm qhov chaw tsim kho

Cov thawv xa khoom ntawm qhov chaw tsim kho tuaj yeem muab faib ua cov thawv xa khoom dav dav, cov thawv ntim khoom ruaj khov thiab cov thawv xa khoom txawb.
