Umnxeba endiwufumana rhoqo kwiinkampani zombane uthi: “Umzobo uthi i-ESE arrester. Ngowuphi umodeli — 2500, 4500 okanye 6000?” Impendulo ayikhethi; kukubalwa, kwaye inombolo yomzekelo yeyona nto ifakwa kuqala. Kolu sapho lwemveliso, inombolo ifaka iklasi yentloko ebangela ukuqhubela phambili — ixabiso le-ΔT, kwiiklasi ze-25 / 45 / 60 microsecond, apho i-NF C 17-102 radius formula iguqula ibe ziimitha zokugubungela okukhuselekileyo. I-ESE2500 yintloko edibeneyo yokuphakama okuncinci kunye neenyawo eziqinileyo; i-ESE4500 luhlobo oluphakathi olugubungela uninzi lwezakhiwo zorhwebo; i-ESE6000 yintloko efikelela ixesha elide yeemasti ezinde, iinyawo ezibanzi okanye amanqanaba okhuseleko angqongqo. Khetha ngokomthetho kwaye ushiya iikona ezikude zophahla zityhilekile okanye uchithe imali eninzi kwisigqubuthelo isakhiwo esingenakusisebenzisa. Esi sikhokelo sikunika ingqiqo yokukhetha kanye njengoko idesika yethu yokuthumela ngaphandle isebenza: oko kuthethwa linani, indlela ifomyula yeradius eyiguqula ngayo ibe yi-coverage, itafile yeklasi yomzekelo ngokwakha, kunye nesixhobo sokubala onokusisebenzisa kwizibalo zakho zeprojekthi.

Inombolo yeModeli yiSpec: Yintoni i-2500, 4500 kunye ne-6000 ene-Encoding

Abathengi ngamanye amaxesha bacinga ukuba amanani ngamanqanaba okuthengisa - alungile, angcono, angcono. Akunjalo; ziiklasi zobunjineli. Inani lilandelela inzuzo yexesha lokuqalisa lentloko ΔT: zingaphi ii-microseconds ngaphambi kokuba intloko iqalise i-upward streamer yayo, elinganiswa kwilebhu ye-high-voltage.Kubai-radius ekhuselweyo ikhula ngokuthe ngqo ngaloo ndlela, inombolo yemodeli ngokuqinisekileyo yiklasi ye-radius. Yingakho ingxelo yovavanyo lwe-ΔT ibaluleke ngaphezu kwefoto yekhathalogu: iintloko ezimbini ezibonakala zifana zinokuba yiklasi eyahlukileyo, kwaye iklasi yinto esetyenziswa kukubalwa kwakho kwe-coverage. Xa sicaphula imodeli, iklasi ye-ΔT kunye namaxwebhu ayo ovavanyo ahamba nekowuteshini, kwaye ndicebisa wonke umntu oza kuthengisa ukuba afune okufanayo kuye nawuphi na umthengisi - lo mkhwa uchazwe kwisikhokelo sethu.amaxwebhu esiqinisekiso emva kokufumana i-ESE.

Ingcaciso enye endiyongeza kuyo yonke incoko yokuqala: amanani eklasi alandela i-NF C 17-102 family convention (25 / 45 / 60 μs tiers), kwaye i-ΔT eqinisekisiweyo yeyunithi ethile yiyo nayiphi na ingxelo yayo yelebhu - ingxelo, hayi ilebhile, yiyo efakwa kwifayile yoyilo ehambelanayo. Ukuba umphicothi weprojekthi yakho ucela ixabiso, ingxelo iyabaphendula; igama lemodeli yikhowudi emfutshane nje ekhokelela wonke umntu kumqolo osekunene wetafile.

Ithini iRadius Formula malunga neSakhiwo sakho?

Ifomula ye-NF C 17-102 yosapho lweradiyo, ye-mast emi iimitha ezingama-h ngaphezulu komphezulu okhuselweyo, yi-R_p= √(2rh − h² + Δ(2r + Δ)), apho i-r yi-rolling-sphere radius yenqanaba lokhuseleko elifunekayo kwaye i-Δ yindlela ebangela ukuba ibonakale kwiimitha (udidi lwe-25 μs lunegalelo kwi-Δ = 25 m, i-45 μs inika i-45 m, kwaye i-60 μs inika i-60 m). Izinto ezintathu eziguquguqukayo, iziphumo ezintathu. Ukuphakamisa i-mast kuphakamisa i-radius kodwa kunciphisa imbuyekezo njengoko i-h isondela kwi-r. Ukuqinisa inqanaba lokhuseleko kunciphisa i-r kwaye kunciphisa yonke i-radius kwiprojekthi. Kwaye ukuphakamisa iklasi ye-ΔT kongeza ukugubungela kuyo nayiphi na i-mast esisigxina - eyi-lever kanye i-ESE2500/4500/6000 choice elawulayo. Ndisebenzisa le fomula kumanani okwenyani omthengi kuyo yonke ikowuteshini,kubaunxibelelwano lunamandla ngokwaneleyo kangangokuba ingqiqo yodwa ihlala ikhetha imodeli engalunganga.

Intloko yesiphelo somoya esabelwana ngayo kusapho lwe-ESE2500/4500/6000 — isixhobo esibangela umsindo ngaphakathi sahlukile ngokweklasi, kwaye ingxelo yaso ye-ΔT yinto emele inombolo yemodeli.

Ukufanisa Iimodeli Neeklasi Zokwakha: Itheyibhile Yokukhetha Esiyicaphulayo

Ifomula esandleni, nantsi imephu esebenzayo esetyenziswa yidesika yethu njengolwazi lokuqala malunga nemibuzo yabakhi - ingqiqo efanayo, ecinezelwe kwitheyibhile esiyicaphulayo ngaphambi kophononongo oluneenkcukacha lomzobo.

Qaphela umqolo wokugqibela — ngulowo abasasazi basibulela ngawo kamva. Iiprojekthi zokulungisa izinto zifika nokuphakama kwe-mast sele kugqunywe sisakhiwo esikhoyo, udonga olubiyelweyo okanye umonde womyili wezakhiwo, kwaye kuloo misebenzi iklasi yemodeli yeyona nto ishiyekileyo yokuthenga ukhuseleko.KubaLe fomula itshintshiselana ngobude ngokuchasene ne-ΔT, ukusuka kwi-4500 ukuya kwi-6000 kubude bemasti obumiselweyo ifumana isilayi esibalulekileyo seradius - ngokuqhelekileyo umahluko phakathi kwemasti enye nezimbini. Isifundo esichaseneyo sibalulekile: ukuba itheyibhile ithi i-2500 igubungela isakhiwo, ukucaphula i-6000 kuthengisa kakhulu, kwaye siza kukuxelela njalo kwikowuteshini ngokwayo.

Inqanaba loKhuselo lingena phi kwiSigqibo?

Inqanaba lokhuseleko lutshintsho oluzolileyo oluthathwa ngabanini-zikontraka.I-IEC 62305-1ifreyimu amanqanaba okhuseleko amane ane-rolling-sphere radii yeemitha ezingama-20, 30, 45 kunye nama-60, kwaye eli nqanaba livela kuhlalutyo lomngcipheko weI-IEC 62305-3indawo — oko kuqulethwe sisakhiwo, ukuba ngubani osikhuselayo, kunye nokuba ukutshaya kuya kubiza malini kwimiphumo kunokuba kulungiswe. Inqanaba I ludidi oluqinileyo lwezibonelelo ezineziphumo eziphezulu; Inqanaba IV ligubungela izakhiwo eziqhelekileyo. Inqanaba lingena kwifomula yeradius nge-r, ngoko ke izakhiwo ezibini ezifanayo ezichazwe kumanqanaba ahlukeneyo zifuna ukugqunywa okwahlukileyo kwi-mast efanayo. Ndicela inqanaba elifunekayo leprojekthi ngaphambi kokuba ndicaphule imodeli,kubaimodeli ehlangabezana neNqanaba lesi-3 ingashiya imfuneko yeNqanaba lesi-2 ingatyhilwanga kubude obufanayo - kwaye "umzobo otshiwo yi-ESE" awulonqanaba.

Ukuba uxwebhu lweprojekthi aluchazi nqanaba, yiphathe loo nto njengombuzo omawuphakanyiswe, kungabi ngumsantsa oza kuphuma ephepheni. Iqela lethu liza kubala ukusuka kwinqanaba elichaziweyo xa unalo kwaye liphawule ingqikelelo xa ungenalo; nokuba yeyiphi na indlela inqaku lokubala lingena kwifayile kunye nengcebiso yomzekelo, ukuze umcebisi abone isiseko endaweni yokuthatha umzekelo ngokholo.

I-terminal ye-ESE efana nekheji evela kuluhlu lwethu: ijiyometri yentloko iyahluka ngokwee-series, kodwa i-logic yokukhetha — udidi, ukuphakama, inqanaba — iyafana kusapho lonke.

Ubude, Unyawo kunye Nokugqunywa Kwesigqubuthelo Esinye: Uyazi Njani Ukuba Intloko Enye Yanele?

Uvavanyo lulula kwaye alunanceba: zoba isangqa esikhuselekileyo kwisicwangciso sophahla. Ukuba irediyasi ebaliweyo R_pUkusuka kwindawo ye-mast kufikelela kwikona nganye yonyawo ngomda, intloko enye yanele; ukuba ikona iwela ngaphandle, ukhetho luyi-mast ende, udidi oluphezulu lwemodeli, okanye indawo yesibini - ngolo hlobo lokukhethwa kophahla oluninzi lwezorhwebo oluthe tyaba.KubaIikona zihlala zifana nejometri eveziweyo, ndicela abakhi ukuba bafumane ububanzi obuphakathi kophahla, hayi indawo: umgama wekona ukusuka kwi-mast linani elimele libethe i-radius. Kuphahla olunemilo ye-L okanye olunezitebhisi uvavanyo olufanayo luqhutywa ngokwendawo nganye, kwaye i-hybrid enezitishi zomoya eziqhelekileyo kwiibhloko zesibini yimpendulo efanelekileyo - uthelekiso lwethuI-ESE ngokuchasene neentonga zesiqhelo zikaFranklinigubungela xa iteknoloji nganye ifumana indawo yayo.

Izikhumbuzo ezimbini ezisebenzayo ezivela kwimisebenzi eyahamba kakuhle. Okokuqala, umoya nokulungisa: imasti ende enentloko phezulu yi-cantilever xa kukho isivuthuvuthu, ngoko ke uyilo lwemasti, ukulungiswa kwesiseko kunye nomgangatho womoya wentloko zifanelekile kwi-submittal efanayo nokubalwa kwe-radius - ii-air terminals zethu zakhiwe ngenkonzo evezwe, kodwa imasti yinto yolwakhiwo ephethwe ngumfaki wakho. Okwesibini, umhlaba: yonke i-joule intloko ethintelayo isahamba iye kwi-conductors ukuya kwi-earth term ekufuneka ihlangabezane nethagethi yayo yokuxhathisa, njengeemfuno zecandelo kunye nomhlaba.I-IEC 62561-2cinga. Imodeli ekhethwe kakuhle emhlabeni osileleyo yinkqubo esileleyo; umgca wethu wezinto ezisisiseko ukho ngokuchanekileyo ukuze zombini iziqingatha zekhonkco zivela kumthengisi omnye onoxanduva.

Inxalenye yoluhlu lwethu lwe-air-terminal: Iintloko ze-ESE kunye neentonga zesiqhelo zithunyelwa ecaleni, kwaye uyilo oluxutyiweyo luyisiphumo esiqhelekileyo sovavanyo lwe-radius endaweni yokuba yinto eyahlukileyo.

Ngawaphi amaxwebhu afanele eze neModeli nganye?

Nokuba imodeli ifika kumzobo, ndixelela abathengi ukuba bacele iseti yephepha efanayo, kuba ibango leklasi lilungile kuphela njengefayile yayo:Ingxelo yovavanyo lokuqalisa kwangaphambili (ΔT)evela kwilebhu evunyiweyo ene-high voltage, elinganiswe ngokweI-IEC 62305-3kunye neprotocol yovavanyo lwe-NF C 17-102; isibhengezo sezinto kunye neplating yentloko; incwadi yokufaka ene-torque kunye neenkcukacha zokufakela; kunye nezatifikethi zovavanyo lohlobo lwe-down-conductor kunye ne-termination hardware ezigqibezela inkqubo phantsiI-IEC 62561-2Ngokwamava am, umthengisi othumela zonke ezine ngaphandle kokugxothwa ngumthengisi ohlolo lwakhe lwefektri luhamba kakuhle.

KubaInani le-ΔT linani elinye elahlula ezi modeli zintathu, andikaze ndamkele ixabiso lencwadana ngokwalo — ingxelo yovavanyo evunyiweyo, hayi ilebheli, yiyo efakwa kwifayile yoyilo ehambelanayo.
