Lattice steel yees ua haujlwm tseem ceeb ntawm cov phiaj xwm xa hluav taws xob, ncaj qha txiav txim siab kev ruaj ntseg thiab kev nyab xeeb ntawm kev xa hluav taws xob. Tom qab ua haujlwm ntev - lub sijhawm ua haujlwm, ntauwd kev ua tau zoo yuav txo qis vim kev yaig ib puag ncig, muaj zog ntxiv thiab cov qauv kev lag luam tshiab. Yog li ntawd, lub hom phiaj kev kho dua tshiab thiab kho dua tshiab ua raws li kev ntsuas tseem ceeb rau kev ua haujlwm ntawm kab hluav taws xob thiab kev saib xyuas nrog rau kev txhim kho kev ua tau zoo, thiab yog qhov tseem ceeb rau kev txhawb nqa siab - kev loj hlob zoo ntawm lub zog hluav taws xob.
Muaj ob tus thawj tsav tsheb rau kev txhim kho ntauwd thiab kho dua tshiab. Rau ib yam, cua, nag thiab corrosion nyob rau hauv tej yam ntuj tso tej yam kev mob ua rau aging Cheebtsam, xeb tsim thiab xoob bolts, undermining cov txheej txheem stability thiab ua rau muaj kev pheej hmoo rau lub hwj chim kis tau tus mob. Ntawm qhov tod tes, cov khoom siv hluav taws xob ua kom nce xyoo los ntawm ib xyoos nrog rau kev hloov kho tshiab kev nyab xeeb. Cov pej thuam qub ua tsis tau raws li cov qauv tam sim no thiab cov khoom siv hluav taws xob xav tau nyob rau hauv cov nqe lus ntawm kev thauj khoom -cov kabmob muaj peev xwm thiab hluav taws xob ua haujlwm, ua rau kev kho dua tshiab tsis tuaj yeem.
Kev tshuaj xyuas thiab kev soj ntsuam xyuas kev tshaj lij yuav tsum tau ua ua ntej kev kho dua tshiab. Cov kws kho mob tau txais cov cuab yeej tshaj lij xws li tsis yog- cov cuab yeej ntsuas kev puas tsuaj kom pom kev puas tsuaj nrog rau cov kab nrib pleb thiab xeb ntawm cov yees. Lawv kuj txheeb xyuas qhov kev ncaj ncees ntawm lub hauv paus, ntauwd ob txhais ceg thiab ntoo khaub lig- caj npab, thiab tsim cov txheej txheem kho dua tshiab raws li qhov chaw nyob thiab kab khiav haujlwm.
Kev kho dua tshiab feem ntau suav nrog kev txhim kho cov txheej txheem thiab txhim kho cov khoom siv hluav taws xob. Raws li cov qauv, cov kab pheeb ces kaum ntxiv thiab cov tswv cuab muaj zog steel tuaj yeem raug teeb tsa, thiab cov khoom corroded hloov los txhim kho tus pej thuam cua tiv thaiv, kev ua haujlwm seismic thiab lub zog ntawm cov qauv. Hluav taws xob, muaj kuab paug- tiv taus thiab ya raws- pov thawj cov insulators tshiab tuaj yeem siv tau, ua ke nrog kev txhim kho loj -section conductors thiab grounding systems, kom tsis txhob muaj teeb meem flashover thiab xob laim, thiab ua kom muaj peev xwm kis tau tus mob thiab kev nyab xeeb ntawm kev ua haujlwm.
Tsis tas li ntawd, cov cai tswj kev nyab xeeb yuav tsum tau ua raws li nruj me ntsis thoob plaws hauv cov txheej txheem kho dua tshiab. Cov neeg ua haujlwm yuav tsum tau nruab nrog cov cuab yeej tiv thaiv, thiab kev tiv thaiv ecological yuav tsum tau muab coj los xav. Kev kho dua tshiab thiab kho dua tshiab tuaj yeem ua tau zoo rau kev pabcuam lub neej ntawm cov yees thiab ua kom muaj kev ntseeg siab thiab kev nyab xeeb ntawm cov phiajcim hluav taws xob.
