Cov SPDs puas tuaj yeem tiv thaiv txhua yam kev cuam tshuam hluav taws xob?
Cov SPDs yog tsim los tiv thaiv feem ntau ntawm cov hluav taws xob surges luv luv, tab sis lawv muaj cov kev txwv raws li lawv qhov kev ntsuas. Lawv yuav tsis tiv thaiv tag nrho cov hluav taws xob surges siab heev lossis xob laim ncaj qha yog tias lub cuab yeej tsis tau ntsuas kom raug. Rau kev tiv thaiv kom zoo, kev sib xyaw ua ke ntawm ntau hom SPD sib txawv yuav siv tau.
Qhov Sib Txawv ntawm Hom 1, Hom 2 Cov Khoom Siv Tiv Thaiv SPD
Hom 1 SPD yog tsim los tswj cov hluav taws xob siab uas muaj zog heev, feem ntau yog los ntawm xob laim ncaj qha. Cov khoom siv no feem ntau raug ntsia rau ntawm qhov nkag ntawm lub tsev, muab kev tiv thaiv thawj zaug tiv thaiv cov xwm txheej hnyav. Hom 1 SPDs muaj peev xwm tswj cov hluav taws xob siab txog li 100 kA lossis ntau dua, siv cov khoom tiv thaiv muaj zog siab xws li cov khoom tiv thaiv cua kom ntseeg tau tias lub kaw lus raug tiv thaiv thaum muaj hluav taws xob siab heev.
Hom 2 SPD muab kev tiv thaiv rau cov khoom faib tawm ntawm lub kaw lus hluav taws xob, daws cov teeb meem surges seem uas tseem muaj tom qab Hom 1 tiv thaiv. Nruab rau ntawm cov vaj huam sib luag faib tawm lossis cov vaj huam sib luag me, Hom 2 SPDs yog tsim los tswj cov hluav taws xob qis dua, feem ntau txog li 20-40 kA ib theem. Cov khoom siv no suav nrog cov khoom siv xws li Hlau Oxide Varistors (MOVs) lossis Gas Discharge Tube (GDTs) los muab kev tiv thaiv txaus rau cov khoom siv tom qab kev tiv thaiv surge thawj zaug.
T1+T2 SPD muab cov txiaj ntsig ntawm Hom 1 thiab Hom 2 SPDs ua ke, muab kev tiv thaiv rau tag nrho lub cev hluav taws xob. Los ntawm kev teeb tsa Hom 1 SPD ntawm qhov nkag hluav taws xob tseem ceeb los daws cov teeb meem hluav taws xob siab thiab Hom 2 SPD hauv lub cev faib khoom rau kev tiv thaiv thib ob, T1 + T2 SPDs ua kom muaj kev tiv thaiv zoo tiv thaiv ntau yam kev hluav taws xob siab. Txoj hauv kev sib koom ua ke no zoo tagnrho rau cov chaw muaj kev pheej hmoo siab xws li cov chaw khaws ntaub ntawv, tsev kho mob, thiab cov chaw ua haujlwm, qhov twg kev tiv thaiv hluav taws xob siab yog qhov tseem ceeb.
Thaum xav tau ntau lub cuab yeej tiv thaiv hluav taws xob ntau dhau (SPDs) los tiv thaiv kev teeb tsa, nws yog ib qho tseem ceeb uas lawv yuav tsum tau sib koom ua ke kom ua haujlwm tau zoo. Yog tias cov SPDs los ntawm ntau lub tuam txhab tsim khoom, nws yog ib qho tseem ceeb uas yuav tsum xyuas kom meej tias lawv sib haum xeeb. Tus neeg teeb tsa thiab cov neeg tsim khoom ntawm cov khoom siv yog cov lus qhia zoo tshaj plaws los xyuas kom meej tias cov SPDs yuav ua haujlwm tau zoo ua ke.
Cov Khoom Siv Tiv Thaiv Surge (SPDs) yog dab tsi?
Ib Lub Khoom Siv Tiv Thaiv Surge (SPD), tseem hu ua lub cuab yeej tiv thaiv surge, yog tsim los tiv thaiv cov khoom siv hluav taws xob los ntawm kev nce hluav taws xob thiab kev hloov pauv hluav taws xob. Nws ua haujlwm ua ib qho tseem ceeb hauv kev tiv thaiv kev teeb tsa hluav taws xob. Ib lub SPD txuas nrog lub voj voog fais fab ntawm cov khoom thauj uas nws tiv thaiv, uas txhais tau tias nws tuaj yeem siv tau ntawm ntau qib ntawm lub network fais fab. Thaum txuas nrog kev hloov pauv, SPD muaj impedance siab nyob rau hauv cov xwm txheej ib txwm muaj. Txawm li cas los xij, thaum muaj kev hloov pauv hluav taws xob, qhov impedance ntawm SPD txo qis, tso cai rau tam sim no surge kom raug xa mus los ntawm lub cuab yeej thiab deb ntawm cov khoom siv rhiab heev. Cov txheej txheem no pab tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob muaj nqis los ntawm kev ua kom ntseeg tau tias lub zog surge ntau dhau tau tswj hwm kom zoo.
