Xob laim muaj kev puas tsuaj loj heev, nrog rau qhov hluav taws xob ncav cuag ntau lab volts thiab cov hluav taws xob tam sim ntawd ncav cuag ntau pua txhiab amperes. Cov txiaj ntsig puas tsuaj ntawm xob laim pom muaj peb theem:
1. Kev puas tsuaj rau cov khoom siv thiab kev raug mob ntawm tus kheej;
2. Txo lub neej ntawm cov khoom siv lossis cov khoom;
3. Kev cuam tshuam lossis kev poob ntawm cov teeb liab thiab cov ntaub ntawv xa lossis khaws cia (analog lossis digital), txawm tias ua rau cov khoom siv hluav taws xob ua haujlwm tsis zoo, ua rau lub cev tsis ua haujlwm ib ntus lossis kaw lub kaw lus.
Qhov uas ib qho chaw saib xyuas yuav raug xob laim puas tsuaj ncaj qha yog me heev. Nrog rau kev txhim kho tas mus li ntawm cov thev naus laus zis niaj hnub no thiab kev siv dav dav thiab kev sib txuas lus ntawm ntau yam khoom siv hluav taws xob zoo, cov neeg ua rau puas tsuaj ntau yam khoom siv hluav taws xob yog vim muaj xob laim overvoltage, kev ua haujlwm overvoltage, thiab xob laim surge intrusion overvoltage. Txhua xyoo, muaj ntau qhov xwm txheej ntawm ntau yam kev tswj hwm kev sib txuas lus lossis network raug xob laim puas tsuaj, suav nrog cov kab ke saib xyuas kev ruaj ntseg uas cov khoom siv puas tsuaj thiab kev ua tsis tiav ntawm kev saib xyuas tsis siv neeg vim muaj xob laim ntaus. Cov koob yees duab pem hauv ntej yog tsim los rau kev teeb tsa sab nraum zoov; hauv cov cheeb tsam uas muaj cua daj cua dub, cov kab ke tiv thaiv xob laim yuav tsum tau tsim thiab teeb tsa.
Cov ncej koob yees duab kev ruaj ntseg hauv tsev feem ntau yog 3-4 meters siab nrog 0.8-meter caj npab, thaum cov ncej koob yees duab kev ruaj ntseg hauv nroog feem ntau yog 6 meters siab nrog 1-meter caj npab kab rov tav.
Xav txog peb yam hauv qab no thaum yuav khoomncej koob yees duab kev ruaj ntseg:
Ua ntej, ib tug ncej tseem ceeb zoo heev.Cov ncej tseem ceeb ntawm cov ncej koob yees duab kev ruaj ntseg zoo yog ua los ntawm cov kav hlau zoo. Qhov no ua rau muaj kev tiv thaiv siab ntxiv. Yog li ntawd, thaum yuav cov ncej koob yees duab kev ruaj ntseg, nco ntsoov xyuas cov khoom siv ntawm cov ncej tseem ceeb.
Qhov thib ob, cov yeeb nkab phab ntsa uas tuab dua.Cov phab ntsa yeeb nkab tuab dua, uas muaj zog tiv taus cua thiab siab zoo dua, feem ntau pom muaj nyob rau hauv cov ncej koob yees duab kev ruaj ntseg zoo. Yog li ntawd, thaum yuav ib tug ncej koob yees duab kev ruaj ntseg, nco ntsoov xyuas seb phab ntsa yeeb nkab tuab npaum li cas.
Qhov thib peb, kev teeb tsa yooj yim.Kev teeb tsa cov ncej koob yees duab zoo feem ntau yooj yim. Kev paub zoo dua ntawm tus neeg siv thiab kev sib tw ntau dua yog ob qho txiaj ntsig ntawm kev ua haujlwm yooj yim dua piv rau cov ncej koob yees duab txheem.
Thaum kawg, raws li hom koob yees duab kev ruaj ntseg uas yuav tsum tau teeb tsa, xaiv ib lub ncej koob yees duab kev ruaj ntseg uas tsim nyog.
Xaiv tus ncej kom tsim nyog los tiv thaiv kev thaiv lub koob yees duab: Yuav kom tau txais txiaj ntsig zoo tshaj plaws ntawm kev saib xyuas, qhov siab ntawm cov ncej rau kev saib xyuas kev ruaj ntseg pej xeem yuav tsum txiav txim siab los ntawm hom koob yees duab; qhov siab ntawm 3.5 txog 5.5 meters feem ntau yog qhov txais tau.
(1) Kev xaiv qhov siab ntawm lub koob yees duab mos txwv:Xaiv cov ncej qis qis, feem ntau ntawm 3.5 thiab 4.5 meters.
(2) Xaiv qhov siab ntawm tus ncej rau lub koob yees duab dome:Cov koob yees duab dome muaj qhov ntev focal uas hloov tau thiab tuaj yeem tig tau 360 degrees. Yog li ntawd, txhua lub koob yees duab dome yuav tsum muaj cov ncej uas siab li siab tau, feem ntau ntawm 4.5 thiab 5.5 meters. Rau txhua qhov siab no, qhov ntev ntawm caj npab kab rov tav yuav tsum tau xaiv raws li qhov deb ntawm tus ncej thiab lub hom phiaj uas tau saib xyuas, nrog rau qhov kev taw qhia ntawm lub thav duab, kom tsis txhob muaj caj npab kab rov tav luv dhau los ntes cov ntsiab lus saib xyuas tsim nyog. Ib txhais caj npab kab rov tav 1-meter lossis 2-meter yog qhov pom zoo kom txo qhov kev thaiv hauv thaj chaw uas muaj kev thaiv.
Tus neeg muag khoom xa ntawv hlauQixiang muaj peev xwm ua cov ncej koob yees duab ruaj ntseg loj. Txawm siv rau hauv cov chaw plaub fab, cov chaw tsim khoom, lossis thaj chaw nyob, peb tuaj yeem tsim cov qauv ncej koob yees duab ruaj ntseg uas tsim nyog. Thov koj xav tiv tauj peb yog tias koj muaj kev xav tau.
