Kutheni i-Zinc oxide ibamba isibane sokukhanyisa sithandwa?

IIZinc oxide ekubambiseni izibanezisetyenziselwa ukhuseleko lwezixhobo zombane kulo lonke uhlobo lwee-voltages ezingaphezulu ezibangelwa kukukhanya okanye ukutshintshwa kwemisebenzi.

(Umgca wokubamba isibane weZinc oxide usebenzisa)

I-Surge arresters esona sikhuseli siphezulu se-voltage emhlabeni, esenziwe nge-metal-oxide (MO) resistors ngaphandle kwe-spark izithuba ezibunjwe ngokuthe ngqo kwizindlu ze-silicone, ngombala ongwevu okanye umbala obomvu, kwaye ziyilwe kwaye zavavanywa ngokwe-IEC 60099-4 kunye ne-IEC. 62848-1.

I-Zinc Oxide yokukhanyisa isakhiwo sangaphakathi sokubamba

Khetha izixhasi ezinokusetyenzwa ngokwemfuneko

Xa kuthelekiswa nesibambisi se-silicon carbide esiqhelekileyo, lo myalelo wemveliso uphucula kakhulu iimpawu ze-volt-Ampere ze-resistor disc kunye nokwandisa amandla akhoyo ngoku kwi-over-voltage ukwenzela ukuba ngexesha lokutshintsha okukhulu kwiimpawu zokubamba.Ngaphantsi kwemeko yombane osebenzayo oqhelekileyo, langoku ngokubanjwa kukwiqondo le-microampere, Xa uhlaselwe yi-voltage engaphezulu, iimpawu ezibalaseleyo ezingahambelaniyo zombambeli ziya kwenza ukuba umsinga wombane unyuke ukuya kumawaka aliqela ampere, ngelixa umbambi uya kuba phantsi. imo ejikelezayo kunye nokukhulula amandla ombane angaphezulu kwe-voltage ukuze kukhuselwe isixhobo sokuhambisa umbane kumonakalo obangelwe kumbane ogqithileyo.

Uphawu lwemveliso

1.Ubungakanani obuncinci, Ubunzima bokukhanya, ukuchasana nempembelelo, akukho monakalo wokungqubana ngexesha lothutho, ukufakwa okuguquguqukayo, kulungele ukusetyenziswa kwi-switch cabin.

2.Isakhiwo esikhethekileyo, ukubunjwa koxinzelelo olupheleleyo, akukho msantsa womoya, ukusebenza kakuhle kokutywinwa, ubungqina bokufuma kunye nobungqina bokudubula.

I-3.Umgama omkhulu we-creepage, i-hydrophobicity enhle, ukuxhathisa okuqinileyo, ukusebenza okuzinzileyo kunye nokunciphisa ukugcinwa komsebenzi.

4.Ifomula eyahlukileyo ye-zinc oxide resistors, ukuvuza okuncinci okwangoku, ukuguga okucothayo, ubomi benkonzo ende.

I-5.Nge-voltage yereferensi ye-DC, umthamo wokuhamba kwe-rectangular kunye nomthamo ophezulu wangoku kunye nobukhulu bangoku obuphezulu bokumelana nomgangatho ophezulu kunemfuno eqhelekileyo.

Usetyenziso

I-Surge arresters ye-medium-voltage systems

Ukukhuselwa kwezixhobo ezivela kumandla ombane ukuya kwi-capacitors yamandla aphezulu, i-arc furnace transformers kunye nezinye

I-Surge arresters kwizicelo ezikhethekileyo kwiinkqubo zombane ophantsi

I-Surge arresters ye-AC traction systems

Izixhobo zokunciphisa amandla ombane kwiinkqubo zokutsala

Imeko yeNkonzo eqhelekileyo

Ubuninzi bamandla: 48Hz ~ 60Hz

Ubushushu be-Ambient:-40°C ~+40°C

Esona santya siphezulu somoya: hayi ngaphezulu kwe-35m/s

Ukuphakama: akudluli kwi-2000m

Ubunzulu benyikima: hayi ngaphezulu kwe-8 degrees

Ubunzima bomkhenkce: abudluli kwiimitha ezili-10.

Umbane osebenza ixesha elide awugqithisi kumandla ombane osebenzayo.

Izixhobo zokubamba

Ababambi banokukhethwa ngokweemfuno zezixhobo: i-Arrester cap, iDisconnector, iCopper line, iBracket njalo njalo.

Izixhobo ezahlukeneyo, imisebenzi eyahlukeneyo, ingasetyenziswa kunye, inokufakwa ngokwahlukileyo.Kodwa iinkcukacha ezahlukeneyo zababambeli, sebenzisa iinkcukacha ezahlukeneyo zezixhobo.

Izincedisi eziphambili zokubamba
