Ndezvipi zviratidzo zvikuru zvinokanganisa mashandiro epoxy glass fiber pombi?

1. Insulation kuramba uye resistivity

Resistance ndiko kudzokororwa kwekuita, uye resistivity ndiko kuramba pavhoriyamu yeyuniti. Iyo diki iyo conductivity yezvinhu, iyo yakakura kupikisa kwayo. Vaviri ava vari muhukama hwehukama. Kune insulating zvinhu, zvinogara zvichidikanwa kuve nepamusoro resistivity sezvinobvira.

2. Relative permittivity uye dielectric kurasikirwa tangent

Insulation zvinhu zvine maitiro maviri: kuvharwa kwezvikamu zvakasiyana-siyana 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 insulation zvinhu zvinoshandiswa pasi pepamusoro frequency uye high voltage, kuitira kuti kurasikirwa kwedielectric kudiki, zvese zvinoda kusarudzwa Insulation. zvinhu zvine dielectric diki kurasikirwa tangent.

3. Kuparara kwemagetsi uye simba remagetsi

Pasi peimwe nzvimbo yakasimba yemagetsi, iyo insulation material yakakuvadzwa, uye basa rekudzivirira rinorasika uye rinova conductive state, iyo inonzi kuparara. Iyo voltage pakuparara inonzi breakdown voltage (dielectric simba). Simba remagetsi ndiyo quotient yevoltage kana kuparara kunoitika pasi pemamiriro enguva dzose uye nguva pakati pema electrode maviri anogashira magetsi akaiswa, kureva, breakdown voltage per unit ukobvu. Zvemidziyo yekudzivirira, kazhinji kukwirisa voltage yekuputsa uye simba remagetsi, zviri nani.

4. Tensile simba

ndiyo yakanyanya kusimba kushushikana iyo sampuli inogamuchira muyedzo yekumanikidza. Ndiyo inonyanya kushandiswa uye yakanyanya kumiririra kuyedza yemakanika basa kuyedza yemidziyo yekuisa.

5. Kupisa kuramba

zvinoreva kugona kwemidziyo yekudzivirira kutsva kana ichibata murazvo kana kudzivirira kuramba uchipfuta kana uchinge wabva mumurazvo. Nekuwedzera kwekushandiswa kwezvinhu zvekudzivirira, izvo zvinodikanwa zvekupisa kwayo kuramba zvinova zvakakosha. Vanhu vakashandisa nzira dzakasiyana siyana kuvandudza uye kusimudzira kuramba kwekupisa kwezvinhu zvekudzivirira. Iyo yakakwirira yekudzivirira kwekupisa, zviri nani kuchengetedzwa.

6. Arc kuramba

Iko kugona kweiyo insulation material kumirisana nearc chiito pamwe nepamusoro payo pasi penguva dzese dzekuedza mamiriro. Mukuyedza, iyo AC yakakwira voltage uye diki ikozvino inosarudzwa, uye kupikisa kwearc kwechinhu chekudzivirira kunotongwa nenguva inodiwa kuti chitarisiko chechinhu chinodzivirira chiite conductive layer nearc mhedzisiro yemhepo yakakwira pakati pe ma electrode maviri. Iyo yakakura kukosha kwenguva, zviri nani kupikisa arc.

7. Dhigirii rekuisa chisimbiso

Chivharo chekuisa chisimbiso chinopesana nemafuta nemhando yemvura chiri nani.
