Rau kev tiv thaiv xob laim ntawm sab nraum zoov muaj tswv yim LED zaub screen cov qauv steel, cov kev ntsuas tshwj xeeb yuav tsum tau coj los ntawm plaub yam: kab teeb liab, hluav taws xob tawm tsam, tawm tsam- tawm tsam los ntawm cov qauv hlau, thiab cov kab hluav taws xob. Cov ntsiab lus yog raws li nram no:
Nyob rau hauv huab cua thunderstorm, cov kab teeb liab yuav tsim hluav taws xob tam sim no vim electromagnetic induction, uas tuaj yeem ua rau lub teeb pom kev zoo. Yog li ntawd, tshwj xeeb teeb liab surge protectors yuav tsum tau ntsia raws li hom teeb liab interface:
Yog hais tias nws yog ib tug network interface, nruab ib lub network teeb liab surge protector;
Yog hais tias nws yog ib tug serial interface (xws li RS-232 / RS-485), nruab ib tug xob tiv thaiv ntaus ntawv rau lub DB9 interface.
Lwm qhov sib cuam tshuam (xws li HDMI, DVI) yuav tsum tau sib xyaw nrog cov khoom siv tiv thaiv xob laim. Cov hluav taws xob ntes hluav taws xob yuav tsum tau txuas nrog hauv cov kab hauv cov teeb liab kis tau tus mob kom ntseeg tau tias cov hluav taws xob tam sim no tau tawm los ntawm cov hluav taws xob ntes mus rau hauv av thiab tsis nkag mus rau hauv cov khoom siv sab hauv.
Direct Lightning Protection Direct xob laim yog qhov kev pheej hmoo ntawm xob laim tawm tsam lub vijtsam lossis cov qauv hlau ncaj qha. Txhawm rau tiv thaiv qhov no, yuav tsum siv tus pas nrig xob laim los coj lub teeb tam sim no ua ntej:
Kev teeb tsa kev teeb tsa: Nruab ib lub pas nrig rau sab saum toj ntawm cov qauv kev txhawb nqa (xws li kab, thav duab) ntawm lub vijtsam sab nraum zoov. Qhov siab ntawm tus pas nrig xob laim yuav tsum npog tag nrho cov zaub screen kom ntseeg tau tias xob laim ua rau tus pas nrig ua ntej.
Kev zam txim: Yog tias lub vijtsam zaub nyob hauv tsev lossis muaj cov tsev siab nyob ze (xws li cov tsev siab lossis cov tsev sib txuas lus), thiab cov tsev twb muaj kev tiv thaiv xob laim, tus pas nrig tuaj yeem raug zam los ntawm kev teeb tsa.
Cov khoom siv: Cov hlua hluav taws xob feem ntau yog ua los ntawm galvanized round steel lossis steel kav, nrog txoj kab uas hla tsis tshaj 25mm. Sab saum toj yog ntse los txhim kho cov nyhuv ntxim nyiam ntawm xob laim.
Yog tias muaj qhov sib txawv ntawm cov qauv steel counterattack tiv thaiv qhov system thiab cov khoom siv tshuaj ntsuam, nws yuav ua rau muaj kev tawm tsam tam sim no, ua rau cov khoom puas. Txhawm rau tshem tawm qhov kev pheej hmoo no, equipotential kev sib txuas thiab hauv av yuav tsum tau txais yuav:
Kev sib npaug muaj peev xwm sib txuas: Txuas cov qauv hlau, tso saib lub npov, cov hlua hlau, thiab lwm yam nrog cov xov hlau los tsim lub cev muaj peev xwm sib npaug, yog li tsis txhob muaj qhov sib txawv.
Cov kev cai hauv av: Tus nqi hauv av yuav tsum tsawg dua 10 ohms. Yog hais tias lub hauv paus ntawm lub cev (xws li lub tsev hauv paus steel tuav) tsis ua raws li qhov yuav tsum tau ua, yuav tsum muaj cov khoom siv hauv av (xws li galvanized lub kaum sab xis steel lossis steel yeeb nkab vertically tsav mus rau hauv av, nrog qhov sib nrug tsis pub tsawg tshaj 5 meters) yuav tsum tau ntxiv.
Grounding ntawm xob laim ntes: Lub grounding terminals ntawm tag nrho cov hluav taws xob ntes (rau cov teeb liab thiab lub zog) yuav tsum tau txuas nrog rau hauv av, thiab yuav tsum tsis txhob muab cov xaim hauv av nrog lwm cov khoom siv.
Cov kab hluav taws xob tiv thaiv hluav taws xob tiv thaiv kab hluav taws xob yog ib txoj hauv kev tseem ceeb los ntawm kev siv hluav taws xob tam sim no nkag. Nws yog tsim nyog rau nruab surge protectors nyob rau hauv theem:
Ib zaug-theem / peb-theem fais fab surge tiv thaiv: Nruab thawj-theem surge protector ntawm lub thawv loj ntawm lub vijtsam zaub kom tso tawm feem ntau ntawm cov xob laim tam sim no; nruab qhov thib ob -theem surge protector nyob rau hauv pem hauv ntej kawg ntawm cov khoom siv ntxiv txwv qhov seem seem;
Hlau txoj kab uas hla: Tus ntoo khaub lig- ntu ntu ntawm theem xaim yuav tsum tsis pub tsawg dua 10mm², thiab tus ntoo khaub lig- ntu ntu ntawm cov xaim hauv av yuav tsum tsis pub tsawg dua 16mm² kom ntseeg tau tias lub peev xwm nqa tau ntawm cov xaim.
Kev teeb tsa qhov chaw: Lub teeb ntes hluav taws xob yuav tsum tau muab tso ze rau ntawm cov khoom tiv thaiv, thiab cov xov hlau txuas yuav tsum luv thiab ncaj li qhov ua tau kom txo qis lub voj induction.
Cov ntsiab lus tseem ceeb rau kev siv:
Cov kev tiv thaiv xob laim yuav tsum tau tsim ib txhij nrog cov duab screen steel qauv kom tsis txhob ua rau cov qauv kev ruaj ntseg thaum lub sij hawm tom qab installation;
Tsis tu ncua ntsuas tus nqi av tiv thaiv (tsawg kawg ib xyoos ib zaug) kom ntseeg tau tias muaj txiaj ntsig zoo ntawm kev tiv thaiv xob laim;
Xaiv cov khoom siv tiv thaiv xob laim uas ua raws li lub teb chaws cov qauv (xws li GB 50057 "Tsim Kev Tiv Thaiv Hluav Taws Xob Hluav Taws Xob") kom tsis txhob siv cov khoom tsis zoo;
Nyob rau hauv ib puag ncig nyuaj (xws li cov chaw ntug dej hiav txwv thiab toj roob hauv pes), qib kev tiv thaiv yuav tsum tau nce kom tsim nyog raws li kev siv hluav taws xob hauv zos.
Los ntawm kev siv cov kev ntsuas no, qhov kev pheej hmoo ntawm sab nraum zoov muaj tswv yim LED zaub screen steel qauv raug ntaus los ntawm xob laim tuaj yeem txo qis, ua kom muaj kev nyab xeeb ntawm cov khoom siv.
