Ndezvipi zvinodiwa zvehunyanzvi zveSMC insulation board

SMC kuputira bhodhi chinhu chakanyanya kufarirwa insulation board chigadzirwa. Kune vatengi vanoda kuitenga, chinhu chekutanga chavanoda kunzwisisa ndechekuda kwayo kwehunyanzvi. Nekuziva chete izvi vanogona kuita sarudzo chaiyo. Tevere, ngatiteverei vagadziri vane hunyanzvi kuti vanzwisise zvinodiwa zveSMC insulation board.

1. Insulation kuramba uye resistivity

Resistance ndiko kudzokororwa kwekuita, uye resistivity ndiko kuramba pavhoriyamu yeyuniti. Izvo zvishoma conductive zvinhu, iyo yakakura kuramba kwayo, uye izvo zviviri zviri muhukama hwehukama. Kune insulating zvinhu, zvinogara zvichidikanwa kuve nepamusoro resistivity sezvinobvira.

2, mvumo yehukama uye dielectric kurasikirwa tangent

Insulating zvinhu zvine maitiro maviri: kuvharwa kwezvikamu zvakasiyana zvemagetsi network uye yepakati ye capacitor (simba rekuchengetedza). Iyo yekutanga inoda diki diki mvumo, iyo yekupedzisira inoda yakakura hama yemvumo, uye ese ari maviri anoda diki dielectric kurasikirwa tangent, kunyanya kune insulating zvinhu zvinoshandiswa pasi pepamusoro frequency uye high voltage, kuitira kuti kurasikirwa kwedielectric kuve kudiki, zvese zvinoda kusarudzwa Insulating. zvinhu zvine dielectric diki kurasikirwa tangent.

3, breakdown voltage uye simba remagetsi

Iyo insulation material yakakuvadzwa pasi peimwe simba remagetsi munda, uye inorasikirwa nekushanda kwekudzivirira uye inova conductive state, iyo inonzi kuparara. Iyo voltage panguva yekuparara inonzi breakdown voltage (dielectric simba). Simba remagetsi ndiyo quotient yevoltage kana kuparara kunoitika pasi pemamiriro enguva dzose uye chinhambwe chiri pakati pemaelectrode maviri anotakura magetsi akaiswa, inova voltage yekuparara payuniti ukobvu. Nezve insulating zvinhu, kazhinji, iyo yakakwirira yekuputsa voltage uye simba remagetsi, zviri nani.

4, kusimba simba

ndiko kushushikana kwekunetseka kunotakurwa nesample muyedzo yekusimba. Inoshandiswa zvakanyanya uye inomiririra kuyedza kweiyo mechanical properties ye insulating materials.

5. Kupikisa kupisa

zvinoreva kugona kwezvidziviriro zvinodzivirira kutsva kana zvasangana nerimi remoto kana kudzivirira kutsva kunoramba kuchibvira kana moto wabuda. Nekuwedzera kwekushandiswa kwezvinhu zvinodzivirira, izvo zvinodikanwa zvekudzivirira kwavo murazvo zvakakosha. Vanhu vakanatsiridza uye vakanatsiridza murazvo wekudzivirira wemidziyo yekumisikidza kuburikidza nenzira dzakasiyana siyana. Iyo yakakwirira yekudzivirira kupisa, zviri nani kuchengetedza.

6, arc kuramba

Pasi pemamiriro ekuyedzwa nguva dzose, iyo insulating material kugona kumira nearc mhedzisiro pairi pamusoro payo. Mukuyedza, iyo AC yakakwira voltage uye diki ikozvino inosarudzwa, uye iyo arc mhedzisiro yeyakakwira voltage pakati pema electrode maviri inoshandiswa kuona kupikisa kwearc yechinhu chinodzivirira panguva inodiwa kuti iyo insulating iite conductive layer. . Iyo yakakura kukosha kwenguva, zviri nani kupikisa arc.

7, dhigirii rekuisa chisimbiso

Zviri nani kuvhara uye kuparadzanisa mafuta nemvura.
