Nezve chikonzero chekutsva kwevaristor

Mudunhu, basa revaristor nderokuti: kutanga, overvoltage kudzivirira;chechipiri, kurwisa mheni zvinodiwa;chechitatu, kuchengeteka kuedza zvinodiwa.Saka nei varistor ichipisa mukati medunhu?Chikonzero chii?

Varistors vanowanzoita basa mukudzivirira kwemagetsi mumaseketi, uye inogona kushandiswa nemafuse ekurova kwemheni kana kumwe kudzivirira kwe overvoltage.Inowanzoshandiswa pakudzivirira mheni.Kana overvoltage ikaitika, varistor ichaputsika uye pfupi pfupi ichaitika, kuitira kuti mhepo pamagumo ose evaristor inosungirirwa panzvimbo yakaderera.Panguva imwecheteyo, iyo overcurrent inokonzerwa nepfupi yedunhu ichapisa fiyuzi yepamberi kana Kumanikidza kuchinjisa mhepo kuti ifambe, nekudaro nekumanikidza kudzima magetsi.Kazhinji kutaura, haina mhedzisiro pane zvimwe zvikamu zvemagetsi mushure mekukuvara, ingotarisa zvikamu zvedunhu zvakabatana nazvo.Munyaya yekukuvara kwepuncture, fuse inoputika.

Kana iyo voltage iri pasi peiyo yakatemerwa voltage yevaristor, kushorwa kwevaristor kusingagumi uye hakuna mhedzisiro mudunhu.Kana iyo voltage iri mudunhu ichipfuura varistor voltage, kushorwa kwevaristor kunodonha nekukurumidza, iyo ichaita basa re shunt uye voltage kudzikamisa, uye fuse iri mudunhu rimwe chete rinoputika kuita basa rekudzivirira.Kana pasina fuse munharaunda, varistor ichaputika zvakananga, kukuvara uye kukundikana, kurasikirwa nekudzivirira kwayo, uye kunokonzera kuti dunhu rinotevera rinopisa.
Zvikonzero zvitatu zviri pamusoro apa ndizvo zvikonzero zvinoita kuti varistor inopisa mukati medunhu.Kunyanya kukoshesa kunofanira kubhadharwa kune kushanda mune ramangwana kudzivirira kukanganisa kune capacitor.
