Kev rwb thaiv tsev piv rau qhov hluav taws xob uas tiv taus tau: Cov lus txhais thiab qhov sib txawv ntawm ob lub cim qhia tseem ceeb rau kev nyab xeeb hluav taws xob

Hauv kev ua haujlwm thiab kev sim cov khoom siv hluav taws xob, kev ua haujlwm rwb thaiv tsev thiab lub peev xwm tiv taus hluav taws xob yog ob qho cim tseem ceeb uas ua kom muaj kev nyab xeeb ntawm cov khoom siv thiab cov neeg ua haujlwm. Lawv feem ntau tsis meej pem, tab sis lawv qhov sib txawv tseem ceeb yog qhov tseem ceeb. Kev piav qhia cov lus txhais thiab qhov sib txawv ntawm lawv yog lub hauv paus ntawm kev tswj hwm kev nyab xeeb hluav taws xob thiab tus yuam sij rau kev zam kev ua tsis tiav ntawm cov khoom siv thiab kev raug mob kev nyab xeeb.

Ua ntej,piav qhia cov ntsiab lus tseem ceeb ntawm ob qho cim qhia:

1.Kev rwb thaiv tsevhais txog lub peev xwm ntawm cov khoom siv hluav taws xob los tiv thaiv kev xau hluav taws xob thiab zam kev tsim cov kev hla ntawm cov khoom siv hluav taws xob lossis ntawm cov khoom siv hluav taws xob thiab av. Nws lub luag haujlwm tseem ceeb yog "cais cov hluav taws xob", uas feem ntau ntsuas los ntawm kev tiv thaiv rwb thaiv tsev, cov ntaub ntawv rwb thaiv tsev (xws li roj hmab, yas), thiab lwm yam, thiab yog qhov kev tiv thaiv yooj yim rau kev ua haujlwm ib txwm ntawm cov khoom siv. 2.Tiv taus qhov hluav taws xobLub zog dielectric, tseem hu ua lub zog dielectric, yog hais txog qhov siab tshaj plaws uas cov khoom siv hluav taws xob lossis cov ntaub ntawv rwb thaiv tsev tuaj yeem tiv taus hauv lub sijhawm teev tseg yam tsis muaj kev puas tsuaj lossis flashover. Nws lub luag haujlwm tseem ceeb yog "tiv taus qhov cuam tshuam ntawm lub zog siab ib ntus", sim qhov ruaj khov ntawm rwb thaiv tsev nyob rau hauv cov xwm txheej hluav taws xob hnyav.

Qib Thib Ob,tqhov sib txawv tseem ceeb ntawm ob qho no feem ntau pom tseeb hauv peb yam:

1.Tlub hom phiaj tseem ceeb txawv

Kev rwb thaiv tsev tsom mus rau "kev tiv thaiv txhua hnub" kom tiv thaiv kev xau tam sim no hauv qab qhov hluav taws xob ua haujlwm ib txwm; qhov hluav taws xob tiv taus tsom mus rau "kev tiv thaiv siab tshaj plaws" kom tiv taus qhov hluav taws xob siab ib ntus xws li xob laim thiab overvoltages.

2.Tcov qauv ntsuas sib txawv

Kev rwb thaiv tsev feem ntau yog txiav txim siab los ntawm tus nqi tsis kam ntawm rwb thaiv tsev, thiab tus nqi siab dua, qhov kev ua tau zoo ntawm rwb thaiv tsev zoo dua; qhov hluav taws xob tiv taus yog txiav txim siab los ntawm qhov hluav taws xob siab tshaj plaws uas nws tuaj yeem tiv taus los ntawm kev sim hluav taws xob tiv taus.

3.Tnws txoj kev sib raug zoo yog sib txawv

Kev ua tau zoo ntawm kev rwb thaiv tsev yog lub hauv paus ntawm lub peev xwm tiv taus hluav taws xob. Cov khoom siv uas tsis rwb thaiv tsev yuav tsis muaj peev xwm tiv taus hluav taws xob txaus, tab sis cov khoom siv uas muaj kev rwb thaiv tsev zoo kuj yuav tsum dhau qhov kev sim hluav taws xob tiv taus kom paub tseeb tias nws muaj kev nyab xeeb hauv qab qhov xwm txheej ua haujlwm hnyav.

Xaus lus, hauv kev sim kev nyab xeeb ntawm cov khoom siv hluav taws xob, ob qho tib si rwb thaiv tsev thiab cov ntsuas hluav taws xob yuav tsum tau them sai sai rau, thiab tsis muaj ib qho twg uas ploj lawm.Hauv kev saib xyuas txhua hnub, tsom mus rau kev sim kev ua haujlwm rwb thaiv tsev thiab kuaj xyuas lub sijhawm rau kev laus thiab kev puas tsuaj ntawm rwb thaiv tsev; ua qhov kev ntsuam xyuas voltage tsis tu ncua kom paub tseeb tias cov khoom siv muaj peev xwm tiv thaiv tau zoo hauv qab qhov hluav taws xob hnyav, kom ntseeg tau tias kev ua haujlwm zoo thiab ruaj khov ntawm lub tshuab hluav taws xob.
