Momwe mungasankhire wopanga zida zoteteza SPD
Mfundo 8 zofunika pakugula zida zoteteza ku China
Ife LSP wopanga China kuyambira 2010, timayesetsa kukhazikitsa chitetezo chokwanira komanso kupanga zida zoteteza za AC DC PV, kuyesetsa kuthandiza makasitomala athu ndi zinthu zabwino kwambiri.
Ngati mukugulitsa zamagetsi, wothandizila, wogulitsa, wogulitsa kapena kugulitsa, mukamagula AC ndi DC kapena PV SPDs (zida zotetezera), muyenera kudziwa mfundo zisanu ndi zitatu zofunika pogula chida choteteza choteteza (SPD) chochokera ku China
1. Zopangira
(1.1) Metal oxide Varistor - MOV
Monga gawo lalikulu lama SPD amkati, osafunikira kunena, mtundu wa SPD umadalira mtundu wa varistors. Mwachidziwikire gwiritsani ntchito MOV wabwino kukhala wofunikira kwambiri, pali zida zambiri zotchuka zachitsulo zosankha monga EPCOS / TDK, Littelfuse, Keko, Varsi…
