Polymer Housed Hlau Oxide Arrester Lightning

Hlau-Oxide teeb pom kev zoo yog ib yam ntawm lub ntiaj teb no siab tshaj overvoltage tiv thaiv tam sim no. Vim tias nws tau qhab nia ntawm qhov tsis kam thov Zno thiab lwm yam hlau oxide los ua, piv nrog cov tsoos carborundum ntes, nws txhim kho VA cov yam ntxwv ntawm Resistance, tsub kom tau txais los ntawm kev muaj peev xwm ntawm kev tiv thaiv, yog li nws coj cov hauv paus hauv qab ua haujlwm voltage, tam sim no. Kev hla tus neeg ntes nkaus xwb A chav kawm, thaum coj tus kabmob overvoltage, qhov zoo tshaj plaws uas tsis yog-linear VA cov yam ntxwv ntawm tus neeg ntes yuav ua rau muaj txiaj ntsig, tam sim no dhau los ntawm tus neeg ntes tau nce siab mus rau ntau txhiab Ampere tam sim, tus neeg ntes tau nyob rau hauv lub xeev, tso tawm tshaj-voltage lub zog, yog li ntawd nws muaj txiaj ntsig txwv qhov kev puas tsuaj rau cov khoom siv hluav taws xob xa mus vim overvoltage.

Cov xwm txheej ntawm kev siv

Cov khoom no yog siv nyob rau hauv kev sib pauv ntawm 220KV thiab hauv qab lub zog tsim, kis tau tus mob, substation, tis systems, thiab systems rau lub sab hauv lub lag luam ntawm lub xob laim tshaj-voltage amplitude yog txwv rau ib tug predetermined theem, tag nrho cov txheej txheem rwb thaiv tsev nrog cov khoom siv yooj yim. Lub caij no, cov khoom siv tsis tuaj yeem siv los txwv cov resonance tshaj-voltage, harmonic tshem tawm cov tshuab yuav tsum tau txais lwm txoj hauv kev.
