Cov kev cai ntawm kev teeb tsa hluav taws xob qhia tias muaj ntau hom kev txhawb nqa hluav taws xob siv hluav taws xob. Lawv qhov kev faib tawm yog qhov tsim nyog, vim hais tias txhua tus ncej muaj nws tus kheej muaj nuj nqi, khaws cov khoom siv hluav taws xob ntau. Tsis tas li ntawd, cov ncej cua yog ua los ntawm cov khoom sib txawv, uas ua rau lawv muaj qee qhov tsis zoo, qhov zoo, thiab tseem muaj ntau txoj hauv kev kho ntawm qhov chaw teeb tsa.
Kev faib tawm los ntawm cov khoom lag luam
Qhov kev faib tawm ntawm lub zog xa hluav taws xob txhawb nqa no yog tsim los ntawm qhov xwm txheej ntawm qhov pom tau tias muaj kev thauj khoom, uas yog, muaj cov ncej uas muaj peev xwm tuav lub zog nruj ntawm cov xov hlau, cables, thiab tseem muaj kev txhawb nqa uas tsim los. rau qhov sib txawv load. Yog li, cov khoom siv hluav taws xob txhawb nqa tau muab faib ua nruab nrab thiab thauj tog rau nkoj. Thawj yog mounted ntawm ncaj seem. Muaj peev xwm tiv taus ntsug loadslos ntawm cable saturation thiab hnyav ntawm insulators, nrog rau kab rov tav cua tsis kam.
Kev txhawb nqa thauj tog rau nkoj yog ib qho qauv uas tau muab tso rau hauv thaj chaw uas cov kev taw qhia ntawm txoj kab hluav taws xob hloov pauv, thaum pib thiab xaus ntawm txoj kev, ntawm kev sib tshuam ntawm txoj kev tsheb ciav hlau, cov dej hauv av, ravines. Nws ruaj khov, ruaj khov piv rau nruab nrab posts. Kev teeb tsa pom tau tias qhov nro (lub zog) ntawm cov xov hlau, cov kab hluav taws xob los ntawm qhov txuas txuas mus rau qhov kev txhawb nqa, yog li kev teeb tsa ntawm kev txhawb nqa thauj tog rau nkoj yog qhov tsim nyog loj rau kev tsim cov kab hluav taws xob muaj zog.
Hom kev txhawb nqa
Nyob ntawm tus qauv tsim, lub hom phiaj ntawm ib ntu ntawm kab, kev txhawb nqa thauj tog rau nkoj tuaj yeem ua rau ntau qhov sib txawv. Namely:
- kawg - mounted ntawm qhov pib thiab qhov kawg ntawm txoj kev, muaj peev xwm ntawm absorbing unilateral rog;
- Lub Anchor Anchor Support - ntsia rau hauv thaj chaw uas cov kev taw qhia ntawm txoj kab hluav taws xob hloov pauv;
- ceg - mounted rau ib ceg ntawm txoj kev loj;
- hla - qhia qhov chaw nyob hauv qhov chaw uas cov kab hluav taws xob sib tshuam;
- transpositional - tau teeb tsa hauv thaj chaw thaum cov theem ntawm kev txhawb nqa nws tus kheej hloov pauv;
- kev hloov pauv - kev teeb tsa cov thauj tog rau nkoj ntawm hom no yog qhov tsim nyog nyob rau hauv qhov chaw uas koj yuav tsum hla kev tsheb ciav hlau lossis txoj kev, dej ntws, dej ntws, dej ntws, thiab lwm yam.
Kev faib tawm los ntawm cov khoom tsim khoom
Tseem muaj ntoo, hlau, pob zeb pob zeb txhawb nqa. Daim duab ua rau nws ua tau kom pom tseeb qhov txawv qhov txawv. Txhua yam khoom muaj nws qhov zoo thiab qhov tsis zoo raws li nws cov yam ntxwv. Nyob ntawm qhov load, qhov ntim ntawm cov kabmob loj ntawm cov xov hlau, qee tus ncej yog mounted. Hlau ncej yog siv los coj txoj kev nrog lub zog siab thiab rau cov ntu ntev. Rau lub vaj, ntiag tug lub hom phiaj, kev txhawb nqa ntoo yog tsim nyog. Txhawm rau muab cov zaub mov hauv nroog, cov khoom siv pob zeb muaj zog feem ntau yog siv. Tsis tas li ntawd, txhawm rau daws qhov teeb meem ntawm kev txhim kho kev txhawb nqa, lawv thov rau lub zog uas qhov kev npaj tau npaj.
Lub hom phiaj, qhov zoo thiab qhov tsis zoo ntawm hom kev txhawb nqa
Kev txhawb nqa ntoo yog siv rau lub zog txog 110 kV. Qhov zoo yog nyob rau hauv tus nqi qis ntawm cov khoom, vim tias ntoo, ib txoj kev tsim khoom, tsis tshua kim dua lwm tus. Qhov tsis zoo, zoo ib yam li cov qauv ntoo, yog qhov cuam tshuam rau rotting, tsim cov pwm tsim kev puas tsuaj, swb ntawm ntoo kab, noog. Cov qauv ntoo yuav tsum tau kho raws sij hawm kom tswj tau nws lub peev xwm thauj khoom.
Hlau ncej yog tsim los rau qhov hluav taws xob ntawm 35 kV. Lawv muaj ntau yam, xav tau kev kho mob raws sij hawm, tab sis muaj kev ruaj khov, hnyav hnyav.
Cov khoom siv ua vaj tse pob zeb yog ntsia rau hauv cov ntu ntawm txoj kev nrog lub zog txog li 500 kV. Qhov zoo dua yog durability, tsis xav taukev pabcuam thaum lub sijhawm ua haujlwm tag nrho. Tam sim no, kev tsim cov pob zeb ua pob zeb muaj qhov loj, xav tau ntawm cov neeg cog lus ua haujlwm rau lub nroog lub zog hluav taws xob sib txuas, thiab tseem yog cov khoom lag luam qis nqi qis.
Ntawm thev naus laus zis rau kev tsim cov pob zeb ua kom muaj peev xwm tsim cov khoom hnyav hnyav, uas txo cov nqi zog, cov khoom ntim, tus nqi, nqi tsheb thauj mus los, txo kev siv cov khoom loj (tshwj xeeb) rau lawv cov installation, tab sis tib lub sij hawm tsis txo lub zog ntawm cov khoom. Qhov tsis zoo ntawm kev txhawb nqa pob zeb yog nws qhov fragility. Piv txwv li, thaum muaj kev huam yuaj, thaum lub tsheb sib tsoo rau hauv tus ncej, nws tawg, ntog, tawg txoj hlua khi, uas tuaj yeem ua rau luv luv thiab hluav taws.
Txhim kho kev txhawb nqa
Txhua hom ncej muaj nws tus kheej thev naus laus zis ntawm kev ntxiv dag zog ntawm qhov chaw teeb tsa. Cov ntoo txhawb nqa yog ntsia los ntawm kev tso ncaj qha rau hauv av, los yog siv cov pob zeb uas muaj zog ntxiv. Thaum txhim kho cov ncej hauv av, nws yog qhov zoo dua los siv ib hom ntoo xws li larch los txo qhov kev pheej hmoo ntawm kev lwj sai ntawm qhov chaw ntawm kev sib cuag ntawm cov khoom nrog cov av. Cov qauv hlau yog ntsia rau ntawm cov pob zeb uas muaj zog ntxiv. Qhov no yog vim qhov tseeb tias cov hlau txhawb nqa muaj qhov siab loj, qhov loj, thiab yog li ntawd yuav tsum tau ruaj khov rau hauv av. Reinforced qhob ncej yog txuas nrog tshwj xeeb anchors uas tau tsim rau hauv lub hauv paus. Fastening feem ntau yog ua los ntawm bolting.
