Tiv thaiv ntsuas rau qhov ntsuas hluav taws xob siab hloov pauv tsis ua hauj lwm

1. Ua tsis tiav los ntawm cov txheej txheem kev tsim khoom lag luam thiab nws txoj kev kho:

Cov khoom siv hluav taws xob hloov pauv yog raws li cov txheej txheem tsim khoom ntawm lub txee. Thaum tsim cov khoom hloov pauv, ua ntej xaiv lub kaum sab xis steel, channel steel thiab lwm cov ntawv siv. Raws li qhov yuav tsum ua ntawm lub txee qauv, cov phaj tsim nyog cov tswvcuab, cov kav hlau tshwj xeeb yog cov welded, thiab kev hloov pauv thiab xav tau kev kho kom haum yog txuas nrog fasteners. Txhawm rau txhawm rau tiv thaiv cov teeb meem tsis zoo uas tshwm sim los ntawm kev sib nrig sib ntxiv ntawm kev sib koom ntawm cov pob qij txha ntawm cov qauv txheej txheem vim yog thermal nthuav ntawm vuam. Cov kev tiv thaiv muaj xws li: kho tom qab vuam; twv seb qhov deformation ntau npaum li cas ua ntej, thiab fim cov kev coj ua tsis ncaj ntawm deformation thaum vuam; yog tias tsim nyog, kev kho cua sov ntawm tus qauv kom zoo; txhawm rau ua rau lub convex ib feem tom qab vuam tib lub zog ntawm kev poob siab raws li qhov txuas, nws yog qhov tsim nyog yuav tsum tau ua kom sov ib feem tau nce.

2. Ua tib zoo saib xyuas cov khoom siv xaiv:

Hauv kev tsim qauv ntawm lub zog, nws yog ib qho tsim nyog yuav tsum tau soj ntsuam xyuas tag nrho cov txiaj ntsig uas tuaj yeem ua rau tsis ua haujlwm ntawm lub pob hloov pauv, yog li yuav tsum ua raws li kev tiv thaiv kev tshawb fawb thiab kev tiv thaiv zoo thaum lub sij hawm tsim. Tam sim no, muaj ntau hom hluav taws xob muaj muag nyob rau ntawm kev ua lag luam, thiab qhov zoo tsis sib xws, uas yuav tsum muaj cov neeg ua haujlwm tsim qauv, yuav tsum tau soj ntsuam qhov kev ua haujlwm thiab siv nyob ntawm cov khoom siv hluav taws xob sib txawv, xaiv cov khoom siv zoo, thiab xyuas kom meej lub teeb hloov pauv yog nyob rau hauv txoj haujlwm zoo tshaj plaws. Zoo mob. Tsis tas li ntawd, qee cov ntaub ntawv ua haujlwm siab kuj tseem tuaj yeem xaiv hauv tus qauv tsim, uas muaj qhov zoo dua ntawm kev txhim kho kev nyab xeeb ntawm cov cuab yeej siv.

3. Ua tib zoo saib rau qhov tsim ntawm creepage piv:

Nyob rau hauv tus txheej txheem ntawm kev tsim switchgear, qhov nkag ntawm qhov chaw nyob deb yog ib qho tseem ceeb heev. Tsuas yog ua kom tau raws li qhov yuav tsum tau ua ntawm qhov ntsuas no tuaj yeem ua kom tag nrho cov hluav taws xob muaj zog ua haujlwm ruaj khov thiab nyab xeeb. Txog qhov nkag ntawm qhov chaw nyob deb, lub tebchaws muaj cov kev cai meej, qhov chaw sab nraud nkag qhov deb ntawm txhua qhov sib xyaw hauv qhov hloov hluav taws xob ntau tsis tsawg tshaj 18mm / kV, thiab cov rwb thaiv tsev organic tsis tsawg dua 20mm / kV. Yuav kom ua tau raws li tus qauv no, chav tsim kho hluav taws xob yuav tsum nruj tswj hwm cov tshwj xeeb ntawm cov khoom siv ntsig txog, thiab yog tias tsim nyog, lawv tuaj yeem nrhiav cov tuam txhab tsim cov khoom lag luam kom tau cov khoom lag luam tshwj xeeb kom ntseeg tau tias muaj kev ntseeg tau thiab ruaj khov ntawm cov hluav taws xob.

4. Lub tshuab nqus tsev Circuit Court tsis ua hauj lwm thiab kho:

Daim duab lub tshuab nqus hluav taws xob qhia yog muaj npe tom qab cov kab hluav taws xob nruab nrab thiab qhov nruab nrab qhov hluav taws xob hauv qhov sib tiv tauj tom qab lub arc tua hluav taws yog ob lub tshuab nqus tsev siab. Nws lub ntsiab yog qhov nqus plua plav kom ua haujlwm thiab ua haujlwm ua haujlwm. Cov kev ua txhaum ntawm lub tshuab nqus tsev Circuit Court feem ntau suav nrog kev kho cua ntawm lub tog paug nyob hauv arc extinguishing chav, uas ua rau lub tshuab hluav taws xob ua tsis ua hauj lwm qhib ib txwm. Yog li ntawd, nws yog qhov yuav tsum tau nce lub tshuab nqus tsev hauv lub tshuab nqus tsev arc extinguishing chav; lub sij hawm ntev txuas ntawm lub tshuab nqus tsev Circuit Court breaker. Kev ua haujlwm ntawm lub rooj vag yuav ua rau qhov chaw txav ntawm lub tshuab txhawm rau plam lossis poob tawm, yog li txo qhov nrawm ntawm lub rooj vag thiab lub rooj vag, thiab ua rau muaj teeb meem xws li kev nkag mus ntawm lub rooj vag ntawm lub qhov rooj solenoid nyob rau hauv lub voj tswj.

5. Xyuam xim rau kev tsim kev nyab xeeb:

Kev Nyab Xeeb yog qhov kev txiav txim siab ua ntej rau txhua qhov haujlwm. Tib yam muaj tseeb hauv txoj kev lag luam fais fab. Kev nyab xeeb ntawm kev siv hluav taws xob yog qhov tseem ceeb tshaj plaws rau kev txhim kho rau lub sijhawm ntev ntawm kev lag luam fais fab. Txhawm rau kom muaj kev nyab xeeb ntawm kev ua haujlwm ntawm lub zog hluav taws xob, qhov kev lag luam fais fab tau tsim cov qauv txheej txheem cuam tshuam. Piv txwv li, cov huab cua sib txawv ntawm cov theem pib ntawm cov hluav taws xob hloov pauv siab thiab hauv av yuav tsum siab dua 125mm. Thaum siv load-insulating qauv, yuav tsum tau them nyiaj rau kev sib koom tes ntawm dielectric constants ntawm cov ntaub ntawv insulating sib txawv. Tsuas yog txoj hauv kev no tuaj yeem tshwm sim ntawm kev raug xwm txheej thiab kev xeb ntawm busbar los ntawm cov pa taws los yog lub cev raug mob tau raug zam.

6. Hais txog qhov ua tau zoo:

Thaum tsim qauv tiv thaiv kev tiv thaiv ntawm lub zog, nws tsis yog tsuas yog yuav tsum tau nruab rau hauv nruj raws li tus qauv, tab sis kuj tseem txuas ntxiv txhim kho kev ua haujlwm ntawm cov kev tiv thaiv txuas kom ua rau nws muaj kev ua tau zoo dua thiab zoo dua kev nyab xeeb kev ua haujlwm ntawm kaw lus fais fab. Cov. Thiab thaum cov kev xa mus hloov, qee qhov tseem ceeb yuav tsum tau rov ua dua tshiab.
