Uhlolojikelele
I-Arrester iyisivikelo se-overvoltage, esisetshenziselwa ikakhulukazi ukuvikela izinto ezahlukene zikagesi (i-transformer, switch, capacitor, arrester, transformer, generator, motor, power cable, njll.) izinhlelo ezifana nesistimu yamandla, uhlelo lokufaka ugesi kaloliwe kanye nohlelo lokuxhumana Ukuvikelwa i-atmospheric overvoltage, i-operation overvoltage kanye nemvamisa yamandla i-overvoltage yesikhashana kuyisisekelo sokuxhumanisa ukufakwa kwesistimu yamandla.Impahla yayo eyinhloko i-zinc oxide.Isibambisi sombani ngokuvamile sixhunywa phakathi kwe-conductor yegridi kanye nentambo yaphansi, futhi ngezinye izikhathi siphinde sixhunywe eduze kwamajika kagesi noma phakathi kwama-conductor.
Isici esiwumgogodla (resistor) se-metal oxide arrester (MOA) samukela ifomula ethuthukisiwe esekelwe ku-zinc oxide, enezici ezinhle kakhulu ezingezona umugqa (i-volt ampere), okungukuthi, ngaphansi kwe-voltage evamile yokusebenza, ukudlula kwamanje kuyileveli encane ye-ampere kuphela. .Uma i-over-voltage yamukelwe, ukudlula kwamanje kungafinyelela izinkulungwane zama-ampere ngokushesha, ngakho-ke isiboshiwe sisesimweni sokuqhuba futhi sikhulula amandla angaphezu kwamandla kagesi, ngaleyo ndlela kukhawule ngempumelelo umonakalo ongaphezu kwamandla kagesi kumishini yokudlulisa nokuguqula.
Isibophisi se-SiC esivamile sinobubi bokukhipha amandla kagesi omqansa ngenxa yokubambezeleka kokukhishwa kwegagasi eliwumqansa, kanye ne-voltage yokukhishwa kwegagasi ephezulu esebenza ngenxa yokuhlakazeka okukhulu kokukhishwa kwegagasi elisebenzayo.Isibambi se-Zinc oxide sinezinzuzo zokusabela okuhle kwamagagasi, akukho ukubambezeleka kwamandla kagesi wamagagasi, ugesi osalayo ophansi, akukho ukuhlakazeka kokukhishwayo, njll. Imajini yokuvikela yamagagasi angumqansa kanye namagagasi okusebenza athuthukiswa kakhulu.Mayelana nokuxhumanisa ukufakwa kwe-insulation, imingcele yokuvikela yamagagasi angumqansa, igagasi lombani kanye negagasi elisebenzayo lingacishe lifane, ukuze kuhlinzekwe isivikelo esingcono kakhulu semishini yamandla.
I-composite sheathed metal oxide arrester yamukela inqubo yonke yokubumba umjovo wokupakisha okubili, okunokusebenza okuhle kokuvala, ukusebenza okuhle kakhulu kokuvikela ukuqhuma, ukumelana nokungcola, asikho isidingo sokuhlanza, kunganciphisa ukuvela kokubaneka okumanzi ezinsukwini ezinenkungu, futhi imelana nokugqwala kukagesi, ukuguga, usayizi omncane, isisindo esincane, futhi kulula ukuyifaka nokuyinakekela.Ingena esikhundleni se-porcelain bushing arrester.
Izici
1. Usayizi omncane, isisindo esilula, ukumelana nokushayisana, akukho monakalo, ukufakwa okuguquguqukayo, okulungele ukushintshwa
2. Isakhiwo esikhethekile, ukubumba sekukonke, alikho igebe lomoya, ukusebenza kahle kokuvalwa, umswakama-umswakama kanye nokuvikela ukuqhuma
3. Ibanga elikhulu le-creepage, ukuxosha amanzi okuhle, ikhono eliqinile lokulwa nokungcoliswa, ukusebenza okuzinzile, nokusebenza okuncishisiwe nokugcinwa kahle
4. I-Zinc oxide resistor, ifomula eyingqayizivele, ukuvuza okuncane, isivinini sokuguga kancane, izici ezinhle zokuphendula, akukho okwamanje okuqhubekayo, umthamo wamanje omkhulu, i-voltage ephansi eyinsalela, ikhono eliqinile lokucindezela ukugcwala ngokweqile, ukumelana nokungcola, ukulwa nokuguga, ukukhululeka emikhawulweni yokuphakama. , isakhiwo esilula, akukho igebe, ukuvalwa okuqinile, impilo ende nezinye izici.
5. I-voltage yangempela yereferensi ye-DC, umthamo wamanje wamagagasi ayisikwele kanye nokubekezelelana okuphezulu kwamanje kuphakeme kunamazinga omhlaba
6. Ngaphansi kwe-voltage yokusebenza yesistimu evamile, lesi sibophelelo sibonisa isimo sokumelana okuphezulu, futhi kudlula okwamanje i-microamp.Ngaphansi kwesenzo se-over-voltage kanye namandla amakhulu, iveza ukumelana okuphansi, ngaleyo ndlela ikhawulele i-voltage eyinsalela kuzo zombili iziphetho zesiboshwa.
Izimo Zokusebenzisa
- Izinga lokushisa le-ambient: -40°C~+40°C
-Isivinini somoya esiphezulu: akukho ngaphezu kwama-35m/s
-Altitude: kufika ku-2000 m
- Amandla okuzamazama komhlaba: akukho ngaphezu kwama-degree angu-8
- Ubukhulu beqhwa: hhayi ngaphezu kwamamitha ayi-10.
- I-voltage esetshenziswa isikhathi eside aweqi ubuningi bevoltheji yokusebenza eqhubekayo.
