Tshawb Nrhiav Qhov Cuam Tshuam ntawm Creepage Distance

Xob laim yog ib qho xwm txheej ntuj tsim uas ua rau peb xav tsis thoob nrog nws qhov zoo nkauj thiab lub zog. Txawm li cas los xij, nws kuj tseem tuaj yeem ua rau peb lub neej thiab khoom muaj kev phom sij. Yuav kom tiv thaiv tau xob laim, cov khoom ntes tau tshwm sim, ntawm cov khoom ntes zinc oxide yog ib qho kev daws teeb meem zoo thiab txhim khu kev qha. Hauv tsab xov xwm no, peb yuav kawm txog cov ncauj lus nthuav txog kev cuam tshuam ntawm qhov deb ntawm cov khoom ntes hluav taws xob thiab qhia txog nws qhov tseem ceeb hauv kev ua kom muaj kev tiv thaiv xob laim zoo.

Ua ntej peb yuav tham txog qhov deb ntawm cov hluav taws xob uas nkag mus rau hauv av, cia peb xub nkag siab txog lub tswv yim ntawm lub cuab yeej tiv thaiv hluav taws xob. Lub cuab yeej tiv thaiv xob laim yog ib lub cuab yeej tsim los tiv thaiv cov kab ke hluav taws xob thiab cov khoom siv los ntawm xob laim. Nws lub hom phiaj tseem ceeb yog kom hloov cov hluav taws xob ntau dhau los ntawm xob laim mus rau hauv av kom muaj kev nyab xeeb, yog li ntawd thiaj li tiv thaiv cov khoom muaj nqis.

Ib qho tseem ceeb hauv kev ntsuam xyuas kev ua haujlwm ntawm lub surge arrester yog qhov deb ntawm creepage. Creepage distance txhais tau tias qhov deb ntawm qhov insulating nto ntawm lub arrester uas xav tau rau lub zog hluav taws xob kom arc thiab tsim txoj hauv kev mus rau hauv av. Hauv cov lus yooj yim, nws txiav txim siab tias lub teeb yuav tsum mus deb npaum li cas hla lub ntsej muag ntawm lub arrester ua ntej mus txog hauv av.

Qhov deb ntawm lub cuab yeej ntes hluav taws xob yog ib qho tseem ceeb uas yuav tsum tau xav txog vim nws cuam tshuam ncaj qha rau qhov ua tau zoo ntawm lub kaw lus tiv thaiv xob laim. Qhov deb ntawm lub cuab yeej ntes hluav taws xob luv dua ua kom muaj kev tso tawm hluav taws xob sai dua thiab ua haujlwm tau zoo dua, tiv thaiv kev puas tsuaj rau cov kab ke hluav taws xob. Ntawm qhov tod tes, qhov deb ntawm lub cuab yeej ntes hluav taws xob ntev dua ua rau muaj kev pheej hmoo ntawm arcing, ua rau muaj kev phom sij overvoltages thiab ua rau cov khoom siv tsis ua haujlwm.

Tam sim no, cia peb tsom mus rau cov zinc oxide arresters thiab lawv cov yam ntxwv tshwj xeeb uas ua rau lawv yog thawj qhov kev xaiv rau kev tiv thaiv xob laim. Zinc Oxide (ZnO) muaj cov khoom siv hluav taws xob zoo heev uas tso cai rau nws nqus cov hluav taws xob siab, ua rau nws yog cov khoom siv zoo tshaj plaws rau cov surge arresters. Tsis tas li ntawd, ZnO surge arresters muaj tus qauv me me rau kev tiv thaiv zoo dua hauv cov ntawv thov uas muaj qhov chaw txwv.

Hais txog qhov deb ntawm qhov nkag mus, cov zinc oxide arresters muaj qhov deb ntawm qhov nkag mus luv dua li lwm hom arresters. Qhov deb ntawm qhov nkag mus no ua rau lub sijhawm teb rau cov xwm txheej xob laim, ua kom muaj kev tiv thaiv cov kab ke hluav taws xob raws sijhawm. Kev tsim qauv thiab cov khoom siv ntawm ZnO arresters ua lub luag haujlwm tseem ceeb hauv kev ua tiav qhov zoo no.
