1. Rwb thaiv tsev kuj thiab resistivity
Resistance yog reciprocal ntawm conductivity, thiab resistivity yog qhov tsis kam ntawm ib chav tsev ntim. Qhov tsawg dua cov khoom siv yog, qhov ntau dua nws qhov kev tiv thaiv, thiab ob qho tib si nyob rau hauv kev sib raug zoo. Rau cov ntaub ntawv insulating, nws yeej ib txwm cia siab tias qhov resistivity yog siab li sai tau.
2. Cov txheeb ze dielectric tas li thiab dielectric poob tangent
Insulating cov ntaub ntawv muaj ob txoj kev siv: kev sib nrig sib rwb thaiv tsev ntawm ntau yam ntawm cov hluav taws xob network thiab dielectric (lub zog cia) ntawm capacitors. Tus qub yuav tsum muaj tus txheeb ze me me dielectric tas li, thiab tom kawg yuav tsum muaj tus txheeb ze loj dielectric tas li. Ob leeg xav tau ib qho me me dielectric poob tangent, tshwj xeeb tshaj yog rau cov ntaub ntawv insulating siv nyob rau hauv high zaus thiab high voltages. Txhawm rau txo qhov poob dielectric, cov ntaub ntawv insulating nrog me me dielectric poob tangent yuav tsum tau.
3. Kev tawg hluav taws xob thiab hluav taws xob muaj zog
Insulating cov ntaub ntawv raug puas tsuaj nyob rau hauv ib tug muaj zog hluav taws xob teb, poob lawv cov rwb thaiv tsev zog thiab ua conductive, uas yog hu ua tawg. Qhov voltage thaum lub sij hawm tawg yog hu ua breakdown voltage (dielectric zog). Lub zog hluav taws xob yog qhov quotient ntawm qhov hluav taws xob thaum lub sij hawm tawg nyob rau hauv cov xwm txheej thiab qhov kev ncua deb ntawm ob lub electrodes raug rau sab nraud voltage, uas yog, qhov tawg voltage ntawm ib chav tsev thickness. Rau cov ntaub ntawv insulating, qhov siab dua qhov tawg voltage thiab lub zog hluav taws xob, qhov zoo dua.
4. Lub zog tensile
Nws yog qhov siab tshaj plaws tensile kev nyuaj siab uas tus qauv dais nyob rau hauv lub tensile xeem. Nws yog qhov siv dav tshaj plaws thiab cov neeg sawv cev xeem rau cov khoom siv hluav taws xob ntawm cov ntaub ntawv insulating.
5. Combustion tsis kam
Nws yog hais txog lub peev xwm ntawm cov ntaub ntawv insulating los tiv thaiv kev kub nyhiab thaum sib cuag nrog cov nplaim taws lossis tiv thaiv kom tsis txhob kub hnyiab thaum tawm hauv cov nplaim taws. Nrog rau kev nce ntxiv ntawm cov ntaub ntawv insulating, cov kev xav tau rau lawv cov combustion kuj tseem ceeb dua. Cov neeg siv ntau txoj kev los txhim kho thiab txhim kho kev sib txuas ntawm cov ntaub ntawv insulating. Qhov siab dua qhov combustion tsis kam, qhov kev nyab xeeb zoo dua.
6. Arc tsis kam
Nyob rau hauv cov ntaub ntawv teev kev xeem, lub peev xwm ntawm cov ntaub ntawv insulating los tiv thaiv arc ua raws lawv nto. Thaum lub sij hawm xeem, AC high voltage thiab tsis tshua muaj tam sim no siv. Qhov kev txiav txim arc tsim los ntawm qhov hluav taws xob siab ntawm ob lub electrodes yog siv los txiav txim qhov arc tsis kam ntawm cov khoom siv insulating. Qhov loj dua lub sij hawm tus nqi, qhov zoo dua qhov arc kuj.
7. Sealing degree
Nws yog qhov zoo dua rau kev sib khi thiab cais cov roj thiab dej.
