FAQ

1) Yuav ua li cas cov kev mob ntawm zinc oxide ntes tau txiav txim raws li cov ntaub ntawv kuaj?

Kev ntsuas tam sim no tsis muaj cov kev cai sib thooj (tsuas yog ob peb lub xeev muaj cov qauv kev lag luam), yog li qhov kev sim no tsis tuaj yeem muab cov qauv ncaj qha rau kev txiav txim siab zoo. Cov ntaub ntawv ntsuam xyuas, zoo li qhov ntawd los ntawm lub tshuab hluav taws xob multimeter lossis lub tshuab hluav taws xob ntsuas waveform, tsuas tuaj yeem muab kev ntsuas qhov tseeb - nws tsis tuaj yeem qhia tias tus ntes tau zoo lossis phem.
Cov dej ntws tam sim no sib txawv nrog qhov ntsuas hluav taws xob ntawm zinc oxide ntes. Kev ntsuas hluav taws xob siab dua sib raug rau cov dej xau ntau dua. Rau qhov tseem ceeb tam sim no: - 10kV-35kV: Feem ntau qis dua 0.2mA - 110kV: Feem ntau nyob ib ncig ntawm 0.3mA - 220kV: Feem ntau nyob ib ncig ntawm 0.4mA - 500kV: Feem ntau nyob ib ncig ntawm 0.8mA Cov neeg siv khoom feem ntau tsim lawv tus kheej cov qauv tom qab kev sim ntau.
Kev ntsuas cov ntaub ntawv feem ntau suav nrog qhov tseem ceeb puv -tam sim no, ncov tag nrho-tam sim no, qhov tseem ceeb tiv thaiv tam sim no, ncov tiv thaiv tam sim no, thiab theem kaum sib txawv.
Peb txoj kev sib piv muaj nyob: muab cov ntaub ntawv sib piv nrog cov ntaub ntawv kuaj lub Hoobkas (tsim cov ntaub ntawv sib piv), sib piv cov ntaub ntawv xeem nrog cov ntaub ntawv xeem keeb kwm (cov ntaub ntawv ntev sib piv), thiab muab cov ntaub ntawv sib piv nrog rau lwm cov zinc oxide surge arresters ntawm tib tus qauv (cross-sectional data comparison).

(2) Yuav ua li cas kuaj valve- hom surge arresters?

Cov cuab yeej no tsis tuaj yeem kuaj lub valve - hom surge arresters. Lawv muaj ib lub pob - hom sib txawv mechanism uas qhov voltage tsis tuaj yeem tshaj qhov sib txawv voltage, ua rau muaj kev cuam tshuam nrog xoom to tam sim no.

(3) Vim li cas lub kaum sab xis sib txawv ntawm peb -theem zinc oxide surge arresters?

Qhov no tshwm sim thaum peb -theem siab- cov kab hluav taws xob nyob ze ze, ua rau qhov hluav taws xob cuam tshuam los ntawm ob theem los cuam tshuam rau theem hauv nqe lus nug. Qhov no ua rau lub kaum sab xis me me rau Theem A thiab lub kaum sab xis loj dua rau Phase C. Rau 110kV thiab hauv qab no, qhov cuam tshuam feem ntau tsis pom zoo. Ntawm 220kV, qhov tshwm sim yog kwv yees li 20%, thiab ntawm 500kV thiab siab dua, nws nce mus rau 50%. Feem ntau qhov sib txawv yog tsawg dua 2 degrees, txawm hais tias muaj tsawg zaus, qhov cuam tshuam tseem ceeb tshaj 5 degrees tuaj yeem tshwm sim, ua rau Phase C lub kaum sab xis sib txawv ntau dua 90 degrees.
Ua ntej, qhov no yog qhov tshwm sim ntawm lub cev ib txwm muaj, tsis yog qhov teeb meem nrog lub hauv paus ntsiab lus ntawm kev sim lossis ntsuas. Qhov thib ob, cov cuab yeej siv feem ntau siv los tiv thaiv - cuam tshuam kev suav cov txheej txheem. Siv ob qho tib si software thiab kho vajtse cov tswv yim, lawv suav cov kaum tiag tiag ntawm theem A thiab C raws li cov xwm txheej ntawm theem B.
