Raug tus tiv thaiv thiab xob laim ntes lub cev tsis yog qhov qub.
Txawm hais tias ob qho tib si muaj kev ua haujlwm ntawm kev tiv thaiv overvoltage, tshwj xeeb tshaj yog tiv thaiv xob laim overvoltage, tseem muaj ntau yam sib txawv hauv daim ntawv thov.
1. Cov neeg raug ntes muaj ntau qhov ntsuas hluav taws xob, txij li 0. 38 KV hluav taws xob tsawg rau 500 KV UHV, thaum cov tiv thaiv kab hluav taws xob feem ntau tsuas muaj cov khoom siv hluav taws xob tsawg;
2. Lub ntes raug teeb tsa ntawm lub hauv paus txheej txheem kom tiv thaiv kev nkag ncaj qha ntawm xob laim ntawm cov hluav taws xob tsis txaus. Cov tiv thaiv phais neeg ncaj qha feem ntau ntsia ntawm lub kaw lus theem nrab. Tom qab lub laim ntawm ntes hluav taws xob tshem tawm txoj kev nkag ncaj qha ntawm xob laim ntawm xob laim, xob laim ntes tsis tshem tawm cov xob laim ntawm xob laim. Ntxiv kev ntsuas
3, tus neeg raug ntes yog los tiv thaiv cov cuab yeej hluav taws xob, thiab tus tiv thaiv phais feem ntau yog tiv thaiv cov twj siv hluav taws xob lossis twj siv;
4. Vim tias lub tshuab ntes hluav taws xob txuas nrog lub hauv paus hluav taws xob hluav taws xob, nws yuav tsum muaj qhov ua tau zoo sab nraud rwb thaiv tsev, thiab lub ntsej muag lub cev kuj loj, thiab cov kws tiv thaiv kab mob tuaj yeem ua tau me me vim qhov hluav taws xob tsawg.
Qhov sib txawv ntawm cov neeg tiv thaiv kab mob thiab tus ntes
1, daim ntawv thov daim teb tuaj yeem faib los ntawm theem hluav taws xob. Cov ntsuas hluav taws xob ntawm qhov raug ntes tau yog< 3="" kv="" rau="" 1="" 000kv,="" tsis="" tshua="" muaj="" voltage="" 0.="" 28="" kv,="" 0..="" 5="">
Cov ntsuas hluav taws xob ntsuas ntawm cov tiv thaiv mob siab yog k 1. 2 kV, 380, 2 2 0 ~ 1 0V ~ {{5 .}} V.
2, cov khoom tiv thaiv nws txawv: tus neeg ntes yog tiv thaiv cov khoom siv hluav taws xob, thiab SPD cov tiv thaiv kab hluav taws xob feem ntau tiv thaiv lub teeb liab theem nrab lossis mus rau qhov kawg ntawm qhov ntsuas hluav taws xob thiab lwm lub zog sib txuas.
3. Rwb thaiv tsev theem lossis qib siab txawv yog txawv: qhov ntsuas hluav taws xob theem ntawm cov cuab yeej hluav taws xob thiab cov khoom siv hluav taws xob tsis yog kev txiav txim ntawm qhov ntau, thiab qhov seem hluav taws xob ntawm overvoltage tiv thaiv cov cuab yeej yuav tsum sib phim nrog qhov voltage theem ntawm kev tiv thaiv lub zog.
4. Cov haujlwm sib txawv sib txawv: Cov neeg raug ntes feem ntau tau nruab rau hauv lub kaw lus kom tiv thaiv kev nkag ncaj qha ntawm xob laim ntawm xob laim thiab tiv thaiv cov kab txuas saum toj thiab cov cuab yeej hluav taws xob. SPD tus tiv thaiv kab mob tiv thaiv tau nruab rau hauv lub vev xaib theem ob, uas tshem tawm cov xob laim ntawm cov khoom ntes hauv kev ntes. Tom qab nkag ncaj qha, lossis tus neeg raug ntes tsis muaj cov kev ntsuas ntxiv kom tshem tawm xob laim ntawm xob laim; yog li ntawd, tus ntes raug teeb tsa ntawm kab nkag; SPD raug teeb tsa rau ntawm qhov hluav taws xob kawg lossis lub teeb liab Circuit Court.
5. Ndlwg txaus sib txawv: xob laim ntes vim hais tias lub luag haujlwm tseem ceeb yog tiv thaiv xob overvoltage, yog li nws cov txheeb ze muaj peev xwm loj dua; thiab rau cov khoom siv hluav taws xob, nws cov txheej txheem rwb thaiv tsev muaj ntau me dua li cov cuab yeej hluav taws xob hauv kev nkag siab dav dav, nws yog qhov yuav tsum tau ua rau SPD ntawm xob laim overvoltage Nws tiv thaiv kev ua haujlwm overvoltage, tab sis nws dhau-ntws muaj peev xwm feem ntau me me. (SPD feem ntau nyob rau ntawm qhov kawg thiab yuav tsis txuas ncaj qha rau cov nyiaj siv ua haujlwm ntxiv. Tom qab qhov txwv tam sim no ntawm theem sab saud, xob laim tam sim no tau txwv rau tus nqi qis dua, yog li SPD nrog lub qhov dej ntws tsawg muaj peev xwm tiv thaiv tau tag nrho cov ntws tawm. Tus nqi tsis tseem ceeb, qhov tseem ceeb yog qhov seem ntawm cov seem.)
6, lwm txheej txheej rwb thaiv tsev, ua kom pom tseeb ntawm cov tsis, thiab lwm yam kuj muaj qhov sib txawv loj.
7. Tus tiv thaiv kab hluav taws xob yog qhov tsim nyog rau kev tiv thaiv zoo tiv thaiv ntawm lub tshuab hluav taws xob qis-qis zog. Ntau yam AC / DC khoom siv fais fab tuaj yeem raug xaiv raws li cov kev sib txawv. Lub zog hluav taws xob tiv thaiv muaj qhov sib nrug loj los ntawm kev tiv thaiv pem hauv ntej-kawg tiv thaiv hluav taws xob, kom lub Circuit Court nquag nquag oscillating overvoltage lossis lwm yam dhau-voltage. Kev nplua hluav taws xob tiv thaiv zoo rau cov khoom siv davhlau ya nyob twg, ua ke nrog kev tiv thaiv ua ntej-theem kev tiv thaiv kab mob, tiv thaiv ua haujlwm tau zoo dua.
8. Cov khoom tseem ceeb ntawm tus raug ntes feem ntau yog zinc oxide (ib qho ntawm cov hlau oxide varistor), thiab cov khoom tseem ceeb ntawm tus tiv thaiv hluav taws xob txawv raws qib kev tiv thaiv thiab kev tiv thaiv kev faib tawm (IEC 61312), thiab tus qauv tsim yog txawv. Luag ntes cov neeg laim txhom tib neeg zoo dua.
9. Kev hais lus hauv kev hais lus, tus neeg raug ntes tsis ncav cuag theem ntawm tus neeg saib xyuas kev tiv thaiv nyob rau hauv cov lus teb rau lub sijhawm teb, siab dhau kev cuam tshuam, tiv thaiv kev tiv thaiv zoo, thiab tiv thaiv kev laus.
