Paub txog cov kab hluav taws xob thiab hluav taws xob ntauwd

---

Cov kab nyiaj siv hluav taws xob tau txais kev txhawb nqa los ntawm ntu ntawm cov kav xa hluav taws xob.

Hluav taws xob pylons yog siv rau cov kab nro siab dua.

Thiab ntoo lossis pob zeb ncej feem ntau yog siv rau cov kab nro qis.

Qhov no yog vim cov kab nro siab dua (siab tshaj nro kab) yuav tsum tau ntsia ntawm qhov siab zoo, vim lawv xav tau kev nyab xeeb ntau dua.

Tsuas yog hluav taws xob pylons tuaj yeem them taus nqa cov kab ntawm kaum tawm tons.

Qhov koj pom ntawm txoj kev nyob rau hauv suburbs feem ntau yog kis tau tus yees.

Raws li rau hom towers, muaj miv-head towers, wine-iav yees, rooj vag-zoo li tus yees, V-shaped towers, tus lwm yam.

Voltage ntawm cov kab hluav taws xob overhead

Rated voltage yog hais txog qhov voltage ntawm ob ntawm peb theem ABC.

Tus qauv domestic voltage ntawm 220 volts yog qhov voltage ntawm ib qho ntawm peb theem mus rau hauv av.

Hauv kev muaj tiag, txoj kab uas xa hluav taws xob mus rau hauv tsev yog 380 hluav taws xob.

Thiab peb theem yog sib cais ua ntej nkag mus rau hauv tsev.

Piv txwv, txhua qhov ntawm peb theem ABC txuas nrog rau txhua chav nyob hauv ib lub tsev.

Overhead hauv av kab

Cov kab sib kis kuj tau muab faib ua tam sim no ncaj qha thiab hloov tam sim no (DC thiab AC).

Ib AC mus ncig yog tsim los ntawm theem A, B thiab C.

Sab saum toj ntawm lub tuam tsev kis tau tus mob yog cov kab hluav taws xob, kuj hu ua overhead ground wire.

Cov kab nyob rau hauv cov cheeb tsam uas muaj cua daj cua dub los yog high voltage muaj ob txoj kab hluav taws xob.

Cov kab uas muaj cua daj cua dub tsawg lossis tsis tshua muaj hluav taws xob siv tau tsuas yog ib txoj kab hluav taws xob xwb.

Cov kab hluav taws xob txuas nrog rau cov ncej kom coj cov hlua hluav taws xob mus rau hauv av.

Cov kab hluav taws xob overhead

Hauv qab cov kab hluav taws xob yog cov kab sib kis.

Tus naj npawb ntawm cov xov hlau yog tag nrho cov ntau ntau 3. Cov kab hluav taws xob ib leeg muaj 3 cov hlau, ob-circuit kab muaj 6 cov hlau, thiab plaub-circuit kab muaj 12 cov hlau.

Hauv txhua lub voj voog muaj peb cov xov hlau rau txhua qhov ntawm peb theem A, B thiab C.

Yog vim li cas vim li cas thiaj muaj ntau lub voj voog nyob rau hauv ib lub pej thuam yog vim qhov kev xav ntawm kev sib kis tau thiab hneev taw. This is why the concepts of “line length” and “circuit length” have also been developed.

Rau ob-circuit kab, qhov ntev ntawm Circuit Court yog ob npaug ntawm kab ntev thiab lwm yam.

Nyob rau hauv cov ntaub ntawv ntawm txawv voltage theem, qhov voltage ntawm tus neeg xyuas pib yog siab dua li ntawm tus neeg xyuas pib qis dua.

Qhov no yog vim qhov siab dua qhov voltage, qhov ntau dua qhov yuav tsum tau muaj kev nyab xeeb deb mus rau hauv av.

Cov kab hluav taws xob zoo sib txawv ntawm cov kab sib kis.

Tus qub yog ncaj qha rau saum tus pej thuam, thaum kawg yuav tsum tau muab tshem tawm los ntawm tus pej thuam los ntawm insulators.

Yog tsis muaj insulators, tus neeg xyuas pib luv luv ncaj qha mus rau tus pej thuam.

Insulator yog ib qho khoom siv ntxiv rau cov xov hlau (cov kab hluav taws xob) siv los txhawb thiab ruaj ntseg tus neeg xyuas pib.

Nws tuaj yeem ua kom muaj kev ncua deb thiab rwb thaiv tsev ntawm cov conductors lossis nruab nrab ntawm cov conductors thiab hauv av.

Insulators yuav tsum muaj cov hluav taws xob rwb thaiv tsev muaj zog txaus thiab dej tsis kam.

Peb cia siab tias tsab xov xwm no yuav pab tau koj kom nkag siab txog cov kab nyiaj siv ua haujlwm thiab cov pej thuam hluav taws xob kom raug.

Peb muab cov khoom zoo thiab tus nqi qis ntawm ntau yam overhead kab thiab lawv accessories.

Thov hu rau peb yog tias koj xav tau lawv.
