Cov txiaj ntsig ntawm 66kV zinc oxide arrester

Raws li qhov kev thov rau cov kab ke faib hluav taws xob txhim khu kev qha thiab ua haujlwm tau zoo txuas ntxiv mus, qhov kev xav tau rau cov khoom siv tiv thaiv kev kub ntxhov siab heev tau dhau los ua qhov tseem ceeb. Ib tug neeg ua si tseem ceeb hauv daim teb no yog66kV zinc oxide surge arrester,tsim los muab kev tiv thaiv overvoltage zoo tshaj plaws rau cov kab faib khoom thiab cov khoom siv hluav taws xob. Cov cuab yeej ntes hluav taws xob no siv zinc oxide thiab lwm yam hlau oxides ua lub disk tiv thaiv tseem ceeb, uas txhim kho nws cov yam ntxwv volt-ampere thiab cov peev xwm hla tam sim no piv rau cov cuab yeej ntes hluav taws xob ib txwm muaj.

Cov khoom siv tiv thaiv xob laim zinc oxide 66kV muaj ntau yam zoo uas ua rau lawv yog ib feem tseem ceeb ntawm txhua lub tshuab faib hluav taws xob niaj hnub no. Ib qho ntawm nws cov txiaj ntsig tseem ceeb tshaj plaws yog kev muaj peev xwm tswj tau tam sim no ntawm qhov hluav taws xob ua haujlwm nominal. Qhov no txhais tau tias cov khoom siv tiv thaiv xob laim tuaj yeem txo qhov cuam tshuam ntawm cov xwm txheej overvoltage, tiv thaiv cov khoom siv tseem ceeb thiab cov khoom siv los ntawm kev puas tsuaj. Tsis tas li ntawd, kev siv zinc oxide thiab lwm yam hlau oxides ua lub disk resistor tseem ceeb ua rau cov khoom siv tiv thaiv hluav taws xob ruaj khov thiab ntseeg tau, ua kom ntseeg tau tias kev ua haujlwm ntev hauv cov chaw ua haujlwm nyuaj.

Ntxiv rau qhov ua tau zoo dua, 66kV zinc oxide arresters muab kev tswj hwm lub zog zoo dua, ua rau lawv zoo tagnrho rau cov ntawv thov faib hluav taws xob uas xav tau ntau. Nws txoj kev tsim qauv thiab cov qauv siab heev ua rau lub zog ploj mus thaum muaj teeb meem overvoltage, tiv thaiv tag nrho lub kaw lus faib hluav taws xob los ntawm kev puas tsuaj ntawm xob laim thiab lwm yam kev cuam tshuam hluav taws xob. Qib kev tiv thaiv no yog qhov tseem ceeb rau kev tswj hwm kev ncaj ncees ntawm cov khoom siv tseem ceeb thiab txo qis lub sijhawm tsis ua haujlwm vim muaj hluav taws xob tsis ua haujlwm.

Tsis tas li ntawd xwb, cov cuab yeej tiv thaiv hluav taws xob zinc oxide 66kV tau tsim los muab kev tiv thaiv hluav taws xob overvoltage uas pheej yig thiab zoo, ua rau lawv yog ib qho kev nqis peev zoo rau cov chaw muab hluav taws xob thiab cov neeg ua haujlwm. Nws cov kev ua tau zoo thiab kev ntseeg siab txo qhov xav tau kev saib xyuas thiab hloov pauv ntau zaus, ua rau txuag tau nyiaj ua haujlwm mus sij hawm ntev. Tsis tas li ntawd xwb, nws lub peev xwm los tswj cov hluav taws xob siab tau zoo txo ​​qhov kev pheej hmoo ntawm kev puas tsuaj thiab kev ua tsis tiav ntawm cov khoom siv, ua rau kev txuag tau nyiaj tag nrho thiab kev ua haujlwm zoo.

Hauv kev xaus lus, 66kV zinc oxide arrester sawv cev rau kev nce qib loj hauv kev siv tshuab tiv thaiv overvoltage rau cov kab ke faib khoom. Nws qhov kev ua tau zoo tshaj plaws, kev tswj hwm lub zog thiab kev siv nyiaj tsim nyog ua rau nws yog ib qho tseem ceeb hauv kev ua kom ntseeg tau tias muaj kev ntseeg siab thiab kev ywj pheej ntawm cov khoom siv faib hluav taws xob niaj hnub no. Los ntawm kev siv cov ntaub ntawv siab heev thiab cov txheej txheem tsim kho, lub arrester teeb tsa tus qauv tshiab rau kev txo cov teebmeem ntawm cov xwm txheej overvoltage, tiv thaiv cov khoom siv tseem ceeb thiab txo qis kev pheej hmoo ua haujlwm. Raws li qhov kev thov rau kev faib hluav taws xob txhim khu kev qha thiab ua haujlwm tau zoo txuas ntxiv nthuav dav, 66kV zinc oxide surge arresters yog qhov kev daws teeb meem txhim khu kev qha thiab tsis tuaj yeem ua tau raws li qhov xav tau hloov pauv ntawm kev lag luam.
