Dab tsi yog cov cim tseem ceeb uas cuam tshuam rau kev ua haujlwm ntawm epoxy iav fiber ntau kav?

1. Rwb thaiv tsev kuj thiab resistivity

Resistance yog reciprocal ntawm conductance, thiab resistivity yog qhov tsis kam ntawm ib chav tsev ntim. Qhov me me ntawm cov khoom siv hluav taws xob, qhov ntau dua nws qhov kev tiv thaiv. Ob leeg yog nyob rau hauv kev sib raug zoo. Rau cov ntaub ntawv insulating, nws yog ib txwm xav kom muaj lub siab tshaj plaws resistivity li sai tau.

2. txheeb ze permittivity thiab dielectric poob tangent

Cov ntaub ntawv rwb thaiv tsev muaj ob txoj kev siv: rwb thaiv tsev ntawm ntau yam ntawm cov hluav taws xob network thiab nruab nrab ntawm lub capacitor (lub zog cia). Cov yav tas yuav tsum tau ib tug me me txheeb ze permittivity, lub tom kawg yuav tsum tau ib tug loj tus txheeb ze permittivity, thiab ob leeg yuav tsum tau ib tug me me dielectric poob tangent, tshwj xeeb tshaj yog rau rwb thaiv tsev cov ntaub ntawv siv nyob rau hauv high zaus thiab high voltage, thiaj li yuav ua rau lub dielectric poob me me, ob qho tib si yuav tsum tau xaiv rwb thaiv tsev. cov ntaub ntawv nrog me me dielectric poob tangent.

3. Kev tawg hluav taws xob thiab lub zog hluav taws xob

Nyob rau hauv ib qho chaw muaj zog hluav taws xob, cov khoom siv rwb thaiv tsev puas lawm, thiab kev ua haujlwm rwb thaiv tsev poob thiab nws dhau los ua lub xeev conductive, uas yog hu ua kev puas tsuaj. Qhov hluav taws xob ntawm kev tawg yog hu ua breakdown voltage (dielectric zog). Lub zog hluav taws xob yog qhov quotient ntawm qhov hluav taws xob thaum muaj kev puas tsuaj tshwm sim nyob rau hauv cov xwm txheej tsis tu ncua thiab lub caij nyoog ntawm ob lub electrodes uas tau txais cov hluav taws xob siv hluav taws xob, uas yog, qhov hluav taws xob tawg ntawm ib chav tsev tuab. Rau cov ntaub ntawv rwb thaiv tsev, feem ntau yog qhov siab dua qhov tawg ntawm qhov hluav taws xob thiab lub zog hluav taws xob, qhov zoo dua.

4. Lub zog muaj zog

yog qhov siab tshaj plaws tensile stress uas tus qauv tau txais nyob rau hauv lub tensile xeem. Nws yog qhov kev siv dav tshaj plaws thiab feem ntau cov neeg sawv cev sim rau kev sim ua haujlwm ntawm cov khoom siv rwb thaiv tsev.

5. Hlawv tsis kam

hais txog lub peev xwm ntawm cov ntaub ntawv rwb thaiv tsev los tiv thaiv kev kub nyhiab thaum kov cov nplaim hluav taws lossis tiv thaiv kom tsis txhob kub hnyiab thaum tawm hauv cov nplaim taws. Nrog rau kev siv cov ntaub ntawv rwb thaiv tsev ntau ntxiv, qhov yuav tsum tau ua rau nws cov incineration kuj tseem ceeb dua. Cov tib neeg tau siv ntau txoj hauv kev los txhim kho thiab txhim kho qhov ua kom tsis muaj zog ntawm cov ntaub ntawv rwb thaiv tsev. Qhov siab dua qhov incineration kuj, qhov kev nyab xeeb zoo dua.

6. Arc tsis kam

Lub peev xwm ntawm cov khoom siv rwb thaiv tsev tuaj yeem tiv taus qhov kev ua haujlwm ntawm arc raws nws qhov chaw nyob rau hauv qhov kev sim tsis tu ncua. Hauv kev sim, AC high voltage thiab me me tam sim no raug xaiv, thiab arc tsis kam ntawm cov khoom siv rwb thaiv tsev yog txiav txim los ntawm lub sij hawm xav tau rau cov tsos ntawm cov khoom insulating los tsim ib txheej conductive los ntawm arc nyhuv ntawm high voltage ntawm lub ob electrodes. Qhov loj dua lub sij hawm tus nqi, qhov zoo dua qhov arc kuj.

7. Sealing degree

Lub sealing barrier tiv thaiv roj thiab dej zoo dua.
