Daim ntawv no feem ntau piav qhia txog cov qauv ntawm cov nyiaj siv ua haujlwm, kev xaiv ntawm txhua qhov yuav tsum tau ua, kab khiav ib puag ncig thiab kev suav kab nrog kev sib xyaw ua ke ntawm cov xwm txheej huab cua, cov txheej txheem tsim kab hluav taws xob.Nkag siab txog qhov tseem ceeb ntawm cov khoom siv kho tshuab thiab lub cev ntawm cov hlau;Master tus neeg kho tshuab cuam tshuam ntawm huab cua tej yam kev mob ntawm cov conductors thiab tsim ntawm ua ke meteorological tej yam kev mob, thiab nkag siab txog qhov yooj yim khiav ntawm Circuit Court tsim.

Kev faib tawm thiab cov qauv ntawm cov kab hluav taws xob overhead
1. Kev faib tawm ntawm cov kab sib kis
Cov kab hluav taws xob yog ib feem tseem ceeb ntawm lub zog hluav taws xob, uas yog lub luag haujlwm rau kev sib kis thiab kev faib hluav taws xob.Cov kab uas xa hluav taws xob hluav taws xob los ntawm qhov chaw mus rau qhov chaw thauj khoom hluav taws xob yog hu ua kab sib kis.Txhawm rau txo qhov poob ntawm lub zog hluav taws xob hauv cov txheej txheem sib kis, cov kab sib kis tau txais cov qib sib txawv raws li qhov sib txawv ntawm qhov sib kis thiab muaj peev xwm kis tau tus mob.Tam sim no, qhov sib txawv voltage siv nyob rau hauv Suav teb yog 35, 60, 110, 220, 330, 500kV, thiab lwm yam nyob rau hauv Suav teb, cov kab ntawm 35 ~ 220kV yog hu ua high voltage kis kab, thiab kab ntawm 330 ~ 500kV yog hu ua ultra high voltage kis kab.Tsis tas li ntawd, txoj kab uas muaj lub luag haujlwm rau kev faib hluav taws xob yog hu ua kab xa khoom.Cov theem hluav taws xob ntawm Tuam Tshoj cov kab xa tawm yog: 380V / 220V, 6KV, 10KV, uas yog hais txog cov kab hauv qab 1kV raws li cov kab hluav taws xob qis qis, 1 ~ 10KV kab raws li cov kab hluav taws xob siab.
Cov kab sib kis tuaj yeem muab faib ua cov kab hluav taws xob thiab cov kab hluav taws xob ua haujlwm raws li lawv cov qauv.Piv nrog rau cov kab hluav taws xob, cov kab hluav taws xob siv hluav taws xob muaj ntau qhov zoo, xws li cov qauv yooj yim, siv sijhawm luv luv, kev tsim kho qis, kev saib xyuas yooj yim, kev ua haujlwm zoo thaum tshav kub kub dissipation, muaj peev xwm kis tau tus mob loj thiab lwm yam.Daim ntawv no tsuas yog qhia txog cov kev paub yooj yim ntawm high voltage overhead transmissions.
2. Cov qauv ntawm cov kab hluav taws xob siv hluav taws xob
Cov kab sib kis feem ntau yog siv los txuas cov chaw tsim hluav taws xob hauv cheeb tsam nrog cov chaw sib txuas ntawm sab txais.Txhawm rau khaws qee qhov kev ncua deb ntawm cov xov hlau nyob ntawm lub zog xa hluav taws xob thiab hauv av, siv cov ncej thiab cov yees los txhawb cov xov hlau, raws li pom hauv daim duab 1-1.Kab rov tav nrug nruab nrab ntawm cov kab nruab nrab ntawm cov yees uas nyob ib sab hu ua lub iav nrug.Ib qho tensioning seem yog tsim los ntawm ntau qhov kev ncua deb ntawm ob lub hauv paus yees.Raws li pom nyob rau hauv daim duab #5 ~ #9, tensioning seem yog tsim los ntawm plaub nrug.Yog tias tsuas muaj ib qho kev ncua deb ntawm qhov tensioning seem, nws yog hu ua cais, raws li qhia nyob rau hauv daim duab ntawm pej thuam #9 thiab ntauwd #10.Ib qho kev sib kis kab yog ib txwm tsim los ntawm ntau ntu ntu, suav nrog ntu cais.

Qee cov ntsiab lus hais txog cov kab hla dhau
Ua ntej ntawm tag nrho cov, qee cov ntsiab lus tseem ceeb ntsig txog cov txheej txheem nyiaj siv ua haujlwm tau piav qhia raws li hauv qab no:
(1) Iav nrug - Qhov kev ncua deb ntawm kab rov tav ntawm cov ntsiab lus raug ncua ntawm cov xov hlau ntawm ob lub yees uas nyob ib sab hu ua lub iav nrug, uas feem ntau yog qhia los ntawm, raws li qhia hauv daim duab 1-2.
(2) sag (so) - qhov kev ncua deb ntawm txhua qhov taw tes ntawm cov xaim thiab qhov kev ncua sij hawm nyob rau hauv txoj kev ncaj yog hu ua sag, kuj hu ua so.
Feem ntau, sag yog hais txog qhov siab tshaj plaws sag hauv ib lub iav tshwj tsis yog tias tau teev tseg, thiab feem ntau qhia los ntawm tsab ntawv F, raws li pom hauv daim duab 1-2.Thaum cov hlau raug tshem tawm ntawm qhov sib npaug (qhov siab yog sib npaug), qhov siab tshaj plaws sag nyob rau hauv lub iav nrug nyob rau hauv qhov chaw;Thaum cov hlau raug tshem tawm tsis sib npaug ntawm qhov siab (qhov siab tsis sib npaug), qhov siab tshaj plaws sag hauv lub iav yog kwv yees li ntawm qhov nruab nrab ntawm lub iav qhov deb.

(3) Txwv - Qhov tsawg kawg nkaus tso cai nyob deb ntawm cov hlau thiab hauv av yog hu ua qhov txwv, raws li qhia los ntawm H hauv daim duab 1-2.Tus nqi ntawm kev txwv kev ncua deb tau teev nyob rau hauv kom meej nyob rau hauv cov kev cai rau kev tsim ntawm cov nyiaj siv ua haujlwm kis tau tus mob kab thiab cov kev cai rau kev tsim cov nyiaj siv ua haujlwm faib kab tawm los ntawm Ministry of Electric Fais Fab ntawm peb lub teb chaws.Cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob yog cov khoom siv hluav taws xob, hluav taws xob, hluav taws xob, hluav taws xob, ntauwd, cable thiab lub hauv paus

Cheebtsam ntawm overhead kis kab

Peb muab cov lus piav qhia luv luv ntawm cov haujlwm yooj yim thiab hom ntawm cov khoom siv hluav taws xob hauv hluav taws xob.

1, conductor

Cov hlau yog siv los nqa hluav taws xob tam sim no thiab lub zog hluav taws xob.Feem ntau, cov kab sib kis tau siv ib tus neeg xyuas pib rau txhua theem, tab sis rau ultra high voltage thiab loj muaj peev xwm kis tau tus kab mob, thiaj li yuav txo tau corona kom txo hwj chim poob thiab txo kev cuam tshuam rau xov tooj cua thiab TEEV, theem split conductors feem ntau yog siv, uas yog, ob. , peb, plaub lossis ntau cov xov hlau (feem ntau yog tsau rau hauv lub nplhaib) yog siv.

2. xob laim conductor thiab grounding lub cev

Lub teeb hluav taws xob yog dai rau saum tus ncej pej thuam, thiab txuas nrog lub cev hauv av los ntawm cov xaim hauv av ntawm txhua lub hauv paus ncej.Thaum xob laim huab cua tawm tsam ib txoj kab hluav taws xob, lub teeb hluav taws xob nyob rau saum tus neeg xyuas pib, thiab lub teeb hluav taws xob tam sim no nyob hauv av tau tawm mus rau lub ntiaj teb.Nyob rau hauv txoj kev no, qhov tshwm sim ntawm xob laim ntaus tus neeg xyuas pib raug txo qis, cov kab hluav taws xob rwb thaiv tsev tiv thaiv los ntawm kev puas tsuaj ntawm xob laim overvoltage, thiab kev tiv thaiv xob laim yog muab los ua kom muaj kev nyab xeeb ntawm txoj kab.Tsuas yog saum toj no 110kV voltage qib kab feem ntau teeb tsa, nws cov khoom feem ntau yog galvanized steel strand.

3, loj

Tus ncej ntauwd yog siv los txhawb tus neeg xyuas pib thiab tus neeg xyuas pib xob laim thiab nws cov khoom siv, thiab kom muaj kev nyab xeeb nyob deb ntawm tus neeg xyuas pib, tus neeg xyuas pib thiab tus pej thuam, nrog rau nruab nrab ntawm tus neeg xyuas pib thiab hauv av thiab hla cov khoom lossis lwm lub tsev. .

4. Insulators thiab rwb thaiv tsev hlua

Insulators yog cov khoom tseem ceeb ntawm cov kab hluav taws xob, uas yog siv los txhawb lossis tshem tawm cov xaim los ntawm cov pej thuam thiab xyuas kom cov kab muaj kev ruaj ntseg hluav taws xob rwb thaiv tsev.Vim hais tias nws tsis yog tsuas yog raug rau txhua yam quab yuam thiab voltage, tab sis kuj yuav tiv taus qhov yaig ntawm cov pa phem hauv cov huab cua.

Yog li ntawd, nws yuav tsum muaj lub zog txhua yam txaus, qib rwb thaiv tsev thiab corrosion kuj.

5, kho vajtse

Cov kab hluav taws xob sib txuas ua lub luag haujlwm ntawm kev txhawb nqa, kho thiab txuas cov xov hlau tiv thaiv thiab kev tiv thaiv xob laim hauv cov kab hluav taws xob hla dhau.Thiab tuaj yeem ua kom cov hlua ruaj khov.Muaj ntau hom kub fittings, uas tuaj yeem muab faib ua tsib pawg: hlau clamp, txuas, tiv thaiv thiab xaim kos duab raws li lawv cov khoom thiab siv.

Ncej ntauwd foundation yog tsau rau hauv av kom ntseeg tau tias tus ncej ntauwd tsis qaij, tawg, tawg thiab lwm qhov chaw.Yog hais tias lub pob zeb muaj zog yog ncaj qha faus rau hauv av, vim hais tias qhov chaw hla ntawm tus ncej me me, tus ncej yuav tog hauv cov av dav dav.Thaum lub sij hawm no los tiv thaiv tus ncej tog, feem ntau nyob rau hauv qab ntawm tus ncej cushion ib tug loj cheeb tsam ntawm reinforced pob zeb phaj - chassis, chassis yog los tiv thaiv tus ncej sinking foundation.Ntawm qhov tod tes, txoj haujlwm ntawm lub cable yog txhawm rau txhim kho lub zog ntawm tus pej thuam, dais cov khoom sab nraud ntawm tus pej thuam quab yuam, thiaj li txo cov khoom siv ntawm cov pej thuam;Ntawm qhov tod tes, ua ke nrog cov hlua hlau thiab cov tais hlau, txhawm rau txhim kho tus pej thuam hauv av, kom ntseeg tau tias tus pej thuam tsis qaij, tawg.Ntauwd lub hauv paus raws li qhov sib txawv, geology thiab kev tsim kho, hom siv kuj txawv.
