Kodi Mukudziwa Izi Terminology ya Varistor

Varistor amagwira ntchito yofunika kwambiri pozungulira.Pamene overvoltage kumachitika pakati pa magawo awiri a varistor, makhalidwe a varistor angagwiritsidwe ntchito achepetsa voteji kuti ndi okhazikika voteji mtengo, kuti kupondereza voteji mu dera, kuteteza dera wotsatira.

Ndiye kodi mukudziwa mawu awa: mphamvu yamagetsi, varistor voltage, residual voltage ratio, insulation resistance, mphamvu yapano, ndi kutayikira kwapano kumatanthauza ma varistors?Ngati simukudziwa, werengani nkhaniyi kuti mudziwe.

1. Mphamvu yamagetsi (V): Imadziwikanso kuti voliyumu yamagetsi, imatanthawuza mtengo wamagetsi pa varistor pamene magetsi a DC a 1m adutsa.

2. Varistor voliyumu: Mtengo wa voteji woyezedwa pa malekezero onse a varistor pamene mphamvu yeniyeni (1mA DC) imayenda kupyolera mu mitsempha.

3. Chiŵerengero chamagetsi otsalira: Pamene mphamvu yamakono kupyolera mu varistor ndi mtengo wina, magetsi opangidwa pamapeto onse a varistor amatchedwa voliyumu yotsalira ya mtengo wamakonowu.Chiŵerengero cha voteji yotsalira ndi chiŵerengero cha voteji yotsalira ku voliyumu yamwadzina.

4. Kukana kwa insulation: kukana kwa DC kwa insulator pansi pazikhalidwe zina.Kukaniza kwamtundu wa varistor kumatanthawuza mtengo wokana pakati pa waya wotsogolera (pini) wa varistor ndi malo otchingira a resistor.

5. Kuthamanga kwa mphamvu (kA): nsonga yapamwamba yamtengo wapatali yomwe imaloledwa kudutsa mu varistor pansi pa nthawi yeniyeni ya nthawi ndi chiwerengero cha nthawi, pansi pa kugwiritsa ntchito mphamvu zamakono zamakono.

6. Kutayikira panopa (mA): amatanthauza panopa akuyenda mu varistor pansi pa kutentha kwapadera ndi nsonga DC voteji.

Kumvetsetsa mawu apadera a varistors kungathandize posankha ma varistors.Sankhani wopanga wodalirika pogula ma capacitor a ceramic angapewe mavuto ambiri osafunikira.JYH HSU (kapena Dongguan Zhixu Electronics)sikuti ili ndi mitundu yonse ya ma capacitor a ceramic okhala ndi mtundu wotsimikizika, komanso imaperekanso kutsatsa kopanda nkhawa.Takulandirani kuti mutithandize ngati mukufuna zida zamagetsi.
