Dab tsi yog cov kev cai rau SMC rwb thaiv tsev board

SMC rwb thaiv tsev pawg thawj coj saib yog ib qho khoom siv rwb thaiv tsev nrov heev. Rau cov neeg muas zaub uas xav yuav nws, thawj yam uas lawv xav kom nkag siab yog nws cov kev cai. Tsuas yog los ntawm kev paub txog cov no lawv tuaj yeem xaiv qhov raug. Tom ntej no, cia peb ua raws li cov neeg tsim khoom lag luam kom nkag siab txog cov kev cai ntawm SMC rwb thaiv tsev board.

1. Rwb thaiv tsev kuj thiab resistivity

Resistance yog reciprocal ntawm conductance, thiab resistivity yog qhov tsis kam ntawm ib chav tsev ntim. Cov khoom siv tsawg dua, 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 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 khoom siv hluav taws xob thiab qhov 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 insulating cov ntaub ntawv siv nyob rau hauv high zaus thiab high voltage, thiaj li yuav ua rau lub dielectric poob me me, ob leeg yuav tsum tau xaiv insulating. cov khoom siv nrog me me dielectric poob tangent.

3, tawg voltage thiab hluav taws xob lub zog

Cov khoom siv rwb thaiv tsev yog puas nyob rau hauv ib qho chaw muaj zog hluav taws xob, thiab nws poob qhov kev ua tau zoo ntawm cov rwb thaiv tsev thiab dhau los ua lub xeev conductive, uas yog hu ua kev puas tsuaj. 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 tawg tshwm sim nyob rau hauv cov xwm txheej tsis tu ncua thiab qhov kev ncua deb ntawm ob lub electrodes uas dais qhov siv hluav taws xob, uas yog qhov tawg ntawm qhov hluav taws xob ntawm ib chav tsev tuab. Hais txog cov ntaub ntawv insulating, feem ntau, qhov siab dua qhov tawg voltage thiab hluav taws xob lub zog, qhov zoo dua.

4, lub zog tensile

yog lub tensile stress uas tus qauv dais nyob rau hauv lub tensile xeem. Nws yog ib qho kev siv dav thiab cov neeg sawv cev sim rau cov khoom siv ntawm cov khoom siv insulating.

5. Combustion tsis kam

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 kev kub nyhiab tas li thaum lawv tawm ntawm cov nplaim taws. Nrog rau kev siv cov ntaub ntawv insulating ntau zuj zus, cov kev xav tau rau lawv cov nplaim taws kuj tseem ceeb heev. Cov neeg tau txhim kho thiab txhim kho cov nplaim hluav taws kub ntawm cov ntaub ntawv insulating los ntawm ntau txoj kev. Qhov siab dua qhov combustion resistance, qhov kev nyab xeeb zoo dua.

6, arc tsis kam

Nyob rau hauv kev sim tsis tu ncua, cov khoom siv insulating muaj peev xwm tiv taus cov nyhuv arc raws nws qhov chaw. Hauv kev sim, AC high voltage thiab me tam sim no raug xaiv, thiab cov nyhuv arc ntawm qhov hluav taws xob siab ntawm ob lub electrodes yog siv los txiav txim qhov arc tsis kam ntawm cov khoom insulating thaum lub sij hawm xav tau rau cov khoom siv insulating los tsim cov txheej txheem conductive. . Qhov loj dua lub sij hawm tus nqi, qhov zoo dua qhov arc kuj.

7, sealing degree

Nws yog qhov zoo dua rau kaw thiab cais cov roj thiab dej zoo.
