Lub gantry yog cov qauv uas txhawb nqa cov khoom siv lossis cov tshuab, feem ntau siv rau ntau yam kev lag luam, suav nrog cov chaw ua haujlwm substations. Nws feem ntau muaj ib lub thav duab uas spans ib qhov chaw thiab yog siv los txav cov ntaub ntawv los yog nruab cov khoom siv hluav taws xob. Hauv substations, gantries ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov kab nyiaj siv ua haujlwm thiab cov khoom siv hluav taws xob, kom ntseeg tau tias muaj kev nyab xeeb thiab ua haujlwm ntawm kev faib hluav taws xob.
Substations yog ib qho tseem ceeb ntawm daim phiaj hluav taws xob thiab yog qhov chaw hluav taws xob hloov hluav taws xob los ntawm qhov hluav taws xob siab mus rau qhov hluav taws xob tsawg rau kev xa mus rau cov tsev thiab cov lag luam. Substations yog cov txheej txheem nyuaj thiab feem ntau siv ntau yam khoom siv thiab cov qauv tsim kom tau raws li kev ua haujlwm tshwj xeeb. Ib qho ntawm cov ntaub ntawv tseem ceeb siv hauv kev tsim kho substation yog steel, uas muab lub zog tsim nyog thiab kav ntev.
Cov qauv hlau feem ntau yog siv rau hauv kev tsim kho substation vim lawv lub zog thiab muaj peev xwm tiv taus ib puag ncig hnyav. Steel qauv factories tshwj xeeb nyob rau hauv zus tau tej cov steel Cheebtsam, xws li steel hlab thiab steel ces kaum, uas yog ib qho tseem ceeb rau tsim ib tug muaj zog substation ncej. Cov raj hlau feem ntau siv rau kev txhawb nqa kev tsim kho, thaum lub kaum sab xis steel muab kev ruaj ntseg ntxiv thiab kev txhawb nqa rau tag nrho cov qauv.
Lub substation qauv nws tus kheej yog tsim los rau tsev ntau yam hluav taws xob Cheebtsam, xws li transformers, circuit breakers, thiab switchgear. Cov khoom no feem ntau yog ntsia rau ntawm lub gantry kom yooj yim nkag mus thiab tu. Kev siv lub gantry nyob rau hauv ib lub substation tsis tsuas yog txhim kho kev ua hauj lwm efficiency, tab sis kuj xyuas kom meej tias cov cuab yeej muaj kev nyab xeeb nyob rau hauv, txo qhov kev pheej hmoo ntawm kev huam yuaj.
Ntxiv nrog rau lawv txoj haujlwm ua haujlwm, gantry pab txhawb rau tag nrho cov qauv tsim thiab kev zoo nkauj ntawm lub substation. Kev sib xyaw ua ke ntawm cov qauv hlau thiab cov gantry tsim ib qho kev pom zoo thiab kev teeb tsa ib puag ncig, uas yog qhov tseem ceeb rau ob qho tib si kev ua haujlwm thiab kev xav ntawm pej xeem. Ua tib zoo npaj thiab siv cov qauv no yog qhov tseem ceeb los xyuas kom meej tias lub substation ua haujlwm tau zoo thiab tswj xyuas cov qauv kev nyab xeeb.
Kev tsim ntawm substation gantry yuav tsum coj mus rau hauv tus account ntau yam, nrog rau lub peev xwm thauj khoom, qhov siab, thiab cov cuab yeej tshwj xeeb uas nws yuav txhawb nqa. Cov kws tsim khoom thiab cov tsim qauv tau ua haujlwm ze los tsim lub gantry uas tuaj yeem tiv taus qhov hnyav ntawm cov khoom siv hluav taws xob hnyav thaum muab qhov chaw txaus rau kev saib xyuas. Qhov kev txiav txim siab zoo no tau ua kom ntseeg tau tias cov qauv gantry tsis yog tsuas yog siv tau, tab sis kuj muaj kev nyab xeeb rau cov neeg ua haujlwm uas yuav xav tau nkag mus rau cov khoom siv.
Tsis tas li ntawd, kev siv cov kaum sab xis steel hauv kev tsim kho ntawm lub gantry ua rau nws lub zog thiab ruaj khov. Cov ces kaum no feem ntau yog siv los tsim ib lub thav duab ruaj khov uas tuaj yeem tiv taus lub zog los ntawm cua, seismic kev ua, thiab qhov hnyav ntawm cov khoom siv. Kev sib xyaw ua ke ntawm cov raj steel thiab cov ces kaum hauv lub gantry tsim tsim cov qauv ruaj khov uas yog qhov tseem ceeb rau kev ua haujlwm nyab xeeb ntawm lub substation.
Hauv cov ntsiab lus, gantries yog ib qho tseem ceeb ntawm cov chaw nres tsheb, muab kev txhawb nqa tsim nyog rau cov khoom siv hluav taws xob thiab ua kom muaj kev nyab xeeb rau kev saib xyuas. Kev siv cov txheej txheem steel, nrog rau cov raj steel thiab cov ces kaum, txhim kho cov kav ntev thiab ruaj khov ntawm cov gantries, ua rau lawv yog ib qho tseem ceeb ntawm kev tsim substation. Raws li qhov kev thov rau lub zog txhim khu kev qha txuas ntxiv zuj zus, qhov tseem ceeb ntawm cov khoom tsim tau zoo thiab cov txheej txheem substation tsuas yog nce ntxiv, qhia txog qhov xav tau kev tsim kho tshiab thiab kev ua tau zoo hauv steel qauv cog kev lag luam.
