Txheej txheem cej luam
Arrester yog ib qho kev tiv thaiv overvoltage, uas yog siv los tiv thaiv ntau yam khoom siv hluav taws xob (transformer, hloov, capacitor, ntes, transformer, generator, lub cev muaj zog, fais fab cable, thiab lwm yam) cov tshuab xws li lub zog hluav taws xob, hluav taws xob hluav taws xob thiab kev sib txuas lus tiv thaiv. atmospheric overvoltage, kev khiav hauj lwm overvoltage thiab lub hwj chim zaus transient overvoltage yog lub hauv paus ntawm rwb thaiv tsev kev sib koom tes ntawm lub hwj chim system.Nws cov khoom tseem ceeb yog zinc oxide.Cov hluav taws xob ntes hluav taws xob feem ntau yog txuas nrog ntawm cov kab hluav taws xob thiab cov xaim hauv av, thiab qee zaum nws tseem txuas nrog ze ntawm cov hluav taws xob winding lossis nruab nrab ntawm cov neeg xyuas pib.
Cov ntsiab lus tseem ceeb (resistor) ntawm cov hlau oxide ntes (MOA) tau txais cov qauv qib siab raws li zinc oxide, uas muaj cov yam ntxwv zoo heev nonlinear (volt ampere), uas yog, nyob rau hauv ib txwm ua haujlwm voltage, tam sim no dhau los ntawm tsuas yog micro ampere theem. .Thaum dhau-voltage tau txais, qhov tam sim no dhau los tuaj yeem ncav cuag ntau txhiab amperes tam sim ntawd, yog li tus neeg ntes tau nyob rau hauv lub xeev conduction thiab tso tawm lub zog dhau-voltage, yog li txo qhov kev puas tsuaj ntawm over-voltage rau lub zog xa mus thiab cov khoom siv hloov pauv.
Cov tsoos SiC ntes muaj qhov tsis zoo ntawm qhov siab siab nthwv dej tawm qhov hluav taws xob vim qhov qeeb ntawm cov nthwv dej ntws tawm, thiab ua haujlwm siab nthwv dej tawm hluav taws xob vim qhov tawg loj ntawm kev ua haujlwm yoj tawm.Zinc oxide ntes tau qhov zoo ntawm cov lus teb zoo yoj yoj, tsis muaj ncua sij hawm rau cov yoj yoj voltage, tsis tshua muaj hluav taws xob, tsis muaj paug dispersion, thiab lwm yam.Nyob rau hauv cov nqe lus ntawm rwb thaiv tsev kev sib koom tes, kev tiv thaiv margins ntawm ntxhab nthwv dej, xob laim yoj thiab ua hauj lwm nthwv dej yuav luag tib yam, thiaj li muab kev tiv thaiv zoo tshaj plaws rau cov khoom siv fais fab.
Cov khoom sib xyaw sheathed hlau oxide ntes tau siv tag nrho cov txheej txheem txhaj tshuaj molding ntawm ob qhov kawg ntim, uas muaj kev sib khi zoo, kev ua haujlwm tawg tau zoo, kev ua qias tuaj, tsis tas yuav ntxuav, tuaj yeem txo qhov tshwm sim ntawm ntub flashes nyob rau hauv pos huab hnub, thiab yog resistant rau hluav taws xob corrosion, kev laus, me me, lub teeb hauv qhov hnyav, thiab yooj yim rau nruab thiab tswj.Nws yog ib qho kev hloov rau porcelain bushing arrester.
Nta
1. Cov me me, lub teeb yuag, kev sib tsoo tsis sib haum, tsis muaj kev puas tsuaj, hloov tau yooj yim, haum rau switchgear
2. Cov qauv tshwj xeeb, zuag qhia tag nrho molding, tsis muaj qhov sib txawv ntawm huab cua, kev ua haujlwm zoo sealing, noo noo-pov thawj thiab tawg-pov thawj
3. Loj creepage nrug, zoo dej repellency, muaj zog tiv thaiv muaj kuab paug muaj peev xwm, ruaj khov kev ua tau zoo, thiab txo lub lag luam thiab txij nkawm
4. Zinc oxide resistor, tshwj xeeb mis, me me to tam sim no, qeeb aging ceev, zoo teb cov yam ntxwv, tsis tas mus li tam sim no, loj tam sim no muaj peev xwm, tsis tshua muaj residual voltage, muaj zog muaj peev xwm mus suppress overvoltage, muaj kuab paug kuj, anti-aging, dawb los ntawm qhov siab txwv. , qauv yooj yim, tsis muaj qhov sib txawv, nruj sealing, lub neej ntev thiab lwm yam ntxwv.
5. Qhov tseeb DC siv voltage, square yoj tam sim no muaj peev xwm thiab siab tam sim no kam rau siab yog siab dua li cov qauv thoob ntiaj teb
6. Nyob rau hauv ib txwm ua haujlwm voltage, tus neeg ntes no nthuav tawm lub xeev siab, thiab tsuas yog microamp tam sim no dhau los.Nyob rau hauv qhov kev txiav txim ntawm dhau-voltage thiab tam sim no loj, nws nthuav tawm tsis kam, yog li txwv qhov seem seem ntawm ob qhov kawg ntawm tus ntes.
Tej yam kev mob ntawm kev siv
- Ambient kub: -40 ° C ~ + 40 ° C
-Qhov siab tshaj plaws cua ceev: tsis tshaj 35m / s
- Qhov siab: mus txog 2000 meters
- Av qeeg siv: tsis tshaj 8 degrees
- Ice thickness: tsis ntau tshaj 10 meters.
- Lub sijhawm siv hluav taws xob ntev tsis tshaj qhov siab tshaj plaws ua haujlwm tsis tu ncua.
