1. Direct Lightning Strike Protection (LPS Kev Ntsuam Xyuas)
Hlau tso tsheb hlau luam (plhaub / ru tsev Thickness $\\ge$ 4mm Steel / $\\ge$ 7mm Aluminium):Lub plhaub tank nws tus kheej ua raws li cov huab cua hauv nruab nrab- qhov kev txiav tawm muaj peev xwm ua kom muaj kev nyab xeeb thiab cuam tshuam cov xob laim. Dedicated xob laim rods (air terminals) los yog overhead xov hlau yogtsis xav tau, yog hais tias lub tank yog grounded kom zoo thiab nruab nrog cov nplaim taws.
Hlau Tank (Phaub / ru tsev Thickness < 4mm Steel los yog Aluminium):Kev ywj pheej huab cua terminals ( xob laim rods, masts, los yog overhead shields) yuav tsum tau ntsia. Thaj tsam ntawm kev tiv thaiv (xws li siv lub dov kheej kheej lossis lub kaum sab xis) yuav tsum tau npog tag nrho lub plhaub tank, lub tshuab nqus pa, lub qhov tso pa tawm, thiab tag nrho lwm yam protrusions.
Tsis yog-Metallic / Fiberglass Reinforced Plastic (FRP) Tanks:Kev ywj pheej huab cua terminals los yog ib qho nyiaj siv ua haujlwm catenary hlau yuav tsum tau muab ntsia kom ntseeg tau tias xob laim tawm tsam kev tiv thaiv tsis yog lub plhaub tank. Tag nrho cov khoom siv hlau sib cais ntawm lub tank yuav tsum tau sib txuas thiab hauv av.
2. Earthing and Grounding (Lub ntsiab tseem ceeb tshaj plaws)
Grounding Point Quantity:Steel cia tank yuav tsum muaj yam tsawg kawg nkausob lub ntsiab lus groundingteem symmetrically raws perimeter ntawm lub tank puag.
Qhov yuav tsum tau muaj:Qhov sib nrug deb ntawm qhov chaw hauv av yuav tsum tsis pub tshaj30 meters(Lub taub ntim loj dua xav tau cov ntsiab lus ntxiv).
Av Resistance:Lub impulse grounding kuj yuav tsum yog$\\le$10$\\Omega$. Ib qho kev sib koom ua ke hauv av tau pom zoo, ua ke nrog kev tiv thaiv xob laim, zoo li qub dissipation, thiab cov khoom siv hluav taws xob muaj kev nyab xeeb hauv av.
Down Conductors:Lub plhaub steel tank tuaj yeem ua haujlwm raws li tus neeg xyuas pib. Yog tias siv cov khoom siv tshwj xeeb, kub -dip galvanized puag ncig lossis cov hlau tiaj tus yuav tsum tau hla mus rau sab, nrog rau kev sim disconnect txuas nruab nrab ntawm0.3m thiab 1.0mqib siab tshaj rau kev soj ntsuam niaj hnub.
Foundation Grounding:Txuas lub hauv paus pob zeb rebar (natural grounding electrode) mus rau cov khoom siv hauv av kom ua kom muaj kev ntseeg tau zoo tshaj plaws.
3. Equipotential Bonding ntawm Accessories & Nplaim Arresters
Metallic Component Bonding:Tag nrho cov khoom siv hlau nplaum-xws li lub siab- lub tshuab nqus tsev (ua pa li qub), nplaim taws ntes, ntsuas lub kaus mom, cov neeg taug kev, tub sab lub kaus mom, thiab cov kab ntws tawm - yuav tsum tau sib txuas nrog rau lub tank lub cev. (Flanged lossis bolted kev sib txuas nrog $ ge $ 5 bolts thiab xoom corrosion tsis tas yuav tsum muaj kev sib txuas nrog lwm tus jumpers; txwv tsis pub, cov hlua khi tooj liab hloov tau yuav tsum tau siv).
Flame Arresters:Txhua txoj kab hluav taws xob los yog lub siab- lub tshuab nqus tsev vacuum tawm mus rau hauv qhov chaw yuav tsum tau nruab nrog lub ntsuas hluav taws xob pom zoo kom tsis txhob muaj hluav taws xob los ntawm qhov hluav taws xob hauv zos.
Floating Roof Tanks (yog tias muaj):Shunts los yog hloov tau yooj yim tinned tooj liab cables (yam tsawg kawg nkaus -sectional cheeb tsam ntawm50 mm² os) yuav tsum khi lub ru tsev ntab mus rau lub plhaub tank ntawm ntau qhov chaw (qhov siab tshaj qhov sib nrug ntawm30 m) txhawm rau tshem tawm qhov sib txawv ntawm lub ru tsev thiab lub plhaub.
4. Piping, Bunding, thiab Static Bonding
Inlet / Outlet txheej txheem Piping:Tag nrho cov txheej txheem hlau txuas txuas nrog lub tank yuav tsum tau muab tso rau ntawm qhov chaw nkag. Parallel pipes spaced tsawg dua100 hlisib nrug yuav tsum tau hla- khi txhua30m. Cov yeeb nkab flanges nrog tsawg dua 5 bolts yuav tsum haum nrog kev sib txuas txuas txuas ntxiv.
Secondary Containment / Bunds:Steel dikes, bund phab ntsa, los yog spill containers pallets yuav tsum tau muab tso rau hauv daim phiaj hauv av. Yog hais tias lub tank zaum ntawm ib qho insulated anti-corrosion barrier uas tiv thaiv nws tus kheej lub ntuj- av, tshwj xeeb grounding rods yuav tsum tau tsav.
Static Dissipation (Loading / Unloading):Thaum lub sijhawm ua haujlwm hloov roj, cov tsheb thauj khoom thauj yuav tsum tau txuas rau hauv daim phiaj hauv av los ntawm kev mob siab rau hnyav -lub luag haujlwm zoo li qub hauv av clamps (txuas rau lub hauv paus tseem ceeb) txhawm rau tiv thaiv cov hluav taws xob zoo li qub thaum sau.
5. Instrumentation & Electrical Surge Protection (LEMP Mitigation)
Cov khoom siv hlau nplaum ntawm txhua qhov cuab yeej siv tau nruab rau ntawm lub tank (xws li kub, theem, lossis lub siab xa hluav taws xob) yuav tsum tau txuas hluav taws xob rau lub plhaub tank.
Cov kab hluav taws xob thiab lub zog hluav taws xob yuav tsum raug xa mus los ntawm kub-dip galvanized steel conduits los yog siv cov ntaub thaiv npog, nrog rau cov kav dej / cov ntaub thaiv npog hauv ob qho kawg.
Surge Protective Devices (SPDs) nrog cov qib tiv thaiv hluav taws xob sib txuam nrog cov cuab yeej tiv thaiv hluav taws xob yuav tsum tau muab ntsia rau ntawm qhov chaw nkag ntawm chav tswj lossis lub zog faib hluav taws xob los tiv thaiv cov tshuab hluav taws xob los ntawm xob laim hluav taws xob Impulse (LEMP) kev puas tsuaj.
