Kungani i-Zinc Oxide lighting arrester idumile?

IIsibambi sokukhanyisa i-Zinc oxideasetshenziselwa ukuvikela izinto zikagesi kuzo zonke izinhlobo zama-over-voltage ezibangelwa ukukhanyisa noma ukushintsha ukusebenza.

(Umugqa wokubopha izibani weZinc Oxide usebenzisa)

Ama-Surge arresters ayisivikeli esithuthuke kakhulu se-over-voltage emhlabeni, esenziwe ngezimbangi ze-metal-oxide (MO) ezingenazikhala zenhlansi ezibunjwe ngokuqondile ezindlini ze-silicone, ezinombala ompunga noma ngombala obomvu, futhi zaklanywa futhi zahlolwa ngokuvumelana ne-IEC 60099-4 ne-IEC. 62848-1.

Isakhiwo sangaphakathi se-Zinc oxide lighting arrester

Khetha ama-resistors asebenzayo ngokwesidingo

Uma kuqhathaniswa nesibambisi esivamile se-silicon carbide, lokhu kugunyazwa komkhiqizo kuthuthukisa kakhulu izici ze-volt-Ampere ze-resistor disc futhi kukhuphule amandla amanje ku-over-voltage ukuze kube phakathi nezinguquko ezinkulu ezicini zababophisi.Ngaphansi kwesimo se-voltage evamile yokusebenza, i-current through arrester in just in microampere degree, Uma ihlushwa u-over-voltage, izici ezinhle kakhulu ezingezona umugqa zomuntu oboshiwe zizokwenza amandla amanje ngesibophi anyuke aye ezinkulungwaneni ezimbalwa ze-ampere, kuyilapho oboshiwe ezobe engaphansi. isimo esijikelezayo kanye nokukhulula amandla e-over-voltage ukuze kuvikelwe okokusebenza kokudlulisa amandla emonakalweni odalwe yi-over-voltage.

Isici somkhiqizo

1.Usayizi omncane,Isisindo esilula,ukumelana nomthelela,akukho monakalo wokushayisana ngesikhathi sokuthutha,ukufakwa okuguquguqukayo,okulungele ukusetshenziswa ku-switch cabin.

2.Isakhiwo esikhethekile, ukubunjwa kokucindezelwa sekukonke, alikho igebe lomoya, ukusebenza kahle kokuvala, umswakama-ubumanzi kanye nokuvikela ukuqhuma

3.Ibanga elikhulu le-creepage, i-hydrophobicity enhle, ukumelana namabala okuqinile, ukusebenza okuzinzile nokunciphisa ukulungiswa kokusebenza.

4.Ifomula eyingqayizivele ye-zinc oxide resistors, ukuvuza okuncane kwamanje, ukuguga kancane, impilo ende yesevisi.

5.Nge-voltage yereferensi ye-DC, umthamo wokugeleza ongunxande namandla aphezulu wamanje kanye nomthamo omkhulu wamanje wokubekezelela kuphezulu kunesidingo esijwayelekile.

Izinhlelo zokusebenza

Ama-Surge arresters amasistimu we-medium-voltage

Ukuvikelwa kwezinto zokusebenza kusuka kugesi wamandla kuya kuma-capacitor wamandla aphezulu, ama-arc furnace transformers nokunye

Izibambisi ezihlinzayo zezicelo ezikhethekile kumasistimu angenawo amandla kagesi aphansi

Ama-Surge arresters amasistimu wokudonsa we-AC

Ama-Surge arresters we-DC traction systems

Amadivayisi anciphisa amandla kagesi wezinhlelo zokudonsa

Isimo Sesevisi Esijwayelekile

Imvamisa yamandla:48Hz ~60Hz

Izinga lokushisa le-ambient:-40°C~+40°C

Isivinini somoya esiphezulu: asidluli ku-35m/s

Ukuphakama: akudluli ku-2000m

Amandla okuzamazama komhlaba: angeqi ama-degree angu-8

Ukuqina kweqhwa: akumele kudlule amamitha ayi-10.

I-voltage esebenza isikhathi eside aweqi i-voltage ephezulu yokusebenza eqhubekayo.

Izesekeli zokubopha

Ababoshiwe bangakhethwa ngokuya ngezidingo zezesekeli: Ikepisi yokubopha, Isixhumi, umugqa wethusi, uBracket nokunye.

Izesekeli ezahlukene, imisebenzi ehlukene, ingasetshenziswa ndawonye, ​​ingafakwa ngokuhlukana.Kodwa ukucaciswa okuhlukile kokubopha, sebenzisa ukucaciswa okuhlukile kwezesekeli.

Izesekeli eziyinhloko zokubopha
