1. Cov dej ntws ntawm cov zinc oxide teev yog qhov loj.
Qhov no yog feem ntau reflected hauv lub arrester tus muaj peev xwm nqus tau ntau yam hluav taws xob overvoltage, mus ntev overvoltage thiab kev khiav hauj lwm overvoltage. Cov dej ntws ntawm cov zinc oxide ntim ua los ntawm chuantai yog ua kom tiav rau hauv txoj kab nrog cov kev cai ntawm lub tebchaws. Kab khiav tawm, muaj peev xwm ua kom muaj zog, 4/10 nanosecond loj tsis sib haum, 2ms square wave peev thiab lwm yam kev ntsuas tau zoo tshaj plaws hauv kev ua haujlwm.
2. Cov yam ntxwv kev tiv thaiv zinc oxide tus tau ua tau zoo heev.
Zinc oxide cov ntaub thaiv tau raug siv los tiv thaiv cov khoom siv hluav taws xob hauv lub hwj chim tsim los ntawm kev puas tsuaj, thiab muaj kev tiv thaiv zoo. Vim tias zno nonlinear voltage-ampere yam ntxwv ntawm lub plhaub valve yog qhov zoo heev, ua ib ob peb puas tsawg lub zog ntawm kev ua haujlwm tam sim no nyob hauv kev ua haujlwm tsis muaj zog, pab tsim qauv tsis muaj kev txwv, ua kom nws muaj kev tiv thaiv zoo, . Tam sim no dhau los ntawm lub valve thaum lub siab siv hauj lwm ua haujlwm, nce ceev ceev, tib lub sij hawm txwv lub amplitude ntawm overvoltage, lub overvoltage ntawm lub zog tso tawm, ces zinc oxide valve plates rov qab siab impedance lub xeev, ua hluav taws xob zog ua hauj lwm.
3. Lub sealing ntawm cov zinc oxide cov ntawv tau zoo yog qhov zoo.
Cov khoom ntim tau zoo tshaj plaws yog kev ua kom zoo tshaj qub, kev nyab xeeb zoo, kev tswj foob kom sib ntau, thiab ua kom lub hnab ntim zoo dua, siv lub thawv kom zoo, ua kom lub sealing ruaj khov, ruaj khov ntawm kev tso npe ntes.
4.Cov khoom siv ntawm cov zinc oxide tub ceev xwm.
Peb yam hauv qab no peb pom tau tias:
Av qeeg quab yuam uas raug rau;
Cov nyhuv yog nyob ntawm qhov siab tshaj plaws ntawm cov cua ntawm cov ntaub ntawv teev npe.
Qhov siab tshaj plaws rub tawm ntawm tus neeg xyuas pib yog sab saum toj ntawm lub.
5. Kev ua kom zoo dua qub ntawm kev zinc oxide .
Tus non - clearance zinc oxide tus tau teev muaj kev sib tsoo muaj cov kab mob qis heev.
Nyob ntawm tam sim no, lub nplhaib ntawm tus cai hais txog cov cai hauv teb chaws yog:
Qib II nruab nrab qhov chaw muaj kuab paug: creepage ratio 20mm / kv.
Chav kawm III hnyav chaw muaj kuab paug: creepage piv ntawm 25mm / kv.
Chav kawm IV tshwj xeeb hnyav chaw muaj kuab paug: lub creepage piv yog 31mm / kv.
Kev ua haujlwm siab ntawm kev ua haujlwm zinc oxide.
6. Qhov kev cia siab ntawm lub sij hawm ntev yog nyob ntawm qhov zoo ntawm qhov khoom thiab seb qhov xaiv ntawm cov khoom tsim nyog. Cov khoom zoo uas cuam tshuam rau nws mas muaj cov nram qab no peb yam:
Lub rationality ntawm tag nrho cov qauv ntawm ib tug teev;
Tus cwj pwm txawv ntawm txoj kev ua haujlwm (volt-ampere) thiab kev laus ntawm cov zinc oxide valve phaj.
Lub sealing kev ua ntawm tus C teev.
7. Kev muaj peev xwm ua haujlwm ntau.
Vim tias lub zog muaj zog xws li ib theem zuj zus, nyob rau lub sij hawm ntev ntawm qhov muaj peev xwm thiab ntau yam, xws li kev thim rov qab yuav ua rau qhov nce ntawm qhov muaj zog ntau zaus los yog ua kom siab siab ntawm cov neeg sab nrauv, hluav taws xob ntes nrog ib qho lub sijhawm ntawm qee lub sijhawm muaj hluav taws xob ntau zaus muaj zog npaum li cas.
