Ucingo engiluthola kakhulu kubakhi bezogesi luthi: “Umdwebo uthi i-ESE arrester. Yimuphi umodeli — 2500, 4500 noma 6000?” Impendulo ayiyona into ekhethwayo; ukubala, futhi inombolo yemodeli iwukufaka kokuqala. Kulo mndeni womkhiqizo inombolo ifaka ikhodi yesigaba sokuthuthuka kwekhanda — inani le-ΔT, emakilasini e-microsecond angu-25/45/60, lapho ifomula ye-NF C 17-102 radius iguqula khona ibe amamitha okumbozwa okuvikelwe. I-ESE2500 ikhanda elihlangene lokuphakama okulinganiselwe kanye nezinyathelo eziqinile; i-ESE4500 isigaba esiphakathi esimboza izakhiwo eziningi zezentengiselwano; i-ESE6000 ikhanda elifinyelela isikhathi eside lama-masts amade, izinyathelo ezibanzi noma amazinga okuvikela aqinile. Khetha ngomthetho wesithupha bese ushiya amakhona akude ophahla eveziwe noma uchithe imali eningi ekumbozweni isakhiwo esingenakukusebenzisa. Lo mhlahlandlela ukunika indlela yokukhetha njengoba nje ideski lethu lokuthumela ngaphandle liyisebenzisa: ukuthi inombolo isho ukuthini, ukuthi ifomula ye-radius iyiguqula kanjani ibe yimbozo, ithebula leklasi lemodeli ngokwakha, kanye ne-calculator ongayisebenzisa ngezibalo zakho zephrojekthi.

Inombolo Yemodeli Yiyona Ecacisiwe: Lokho Okubhalwe Ngempela Ku-2500, 4500 kanye No-6000

Abathengi ngezinye izikhathi bacabanga ukuthi izinombolo ziyizinga lokumaketha — zinhle, zingcono, zingcono kakhulu. Azinjalo; ziyizigaba zobunjiniyela. Inombolo ilandelela inzuzo yesikhathi sokuqala sekhanda i-ΔT: ukuthi zingaki imizuzwana emincane ngaphambi kokuba induku yokubhekisela engasebenzi ikhiphe i-upward streamer yayo, elinganiswa elabhorethri ene-voltage ephezulu.Ngobairediyasi evikelwe ikhula ngqo ngaleyo ndlela, inombolo yemodeli empeleni iyiklasi yerediyasi. Yingakho futhi umbiko wokuhlolwa kwe-ΔT ubaluleke kakhulu kunesithombe sekhathalogi: amakhanda amabili abukeka afanayo angaba yiklasi ehlukene, futhi ikilasi yilokho ukubalwa kwakho kokumbozwa okusebenzisayo. Uma sicaphuna imodeli, ikilasi le-ΔT kanye nemibhalo yalo yokuhlola kuhamba nekhotheshini, futhi ngeluleka wonke umakhi ukuthi afune okufanayo kunoma yimuphi umhlinzeki - umkhuba uchazwe kumhlahlandlela wethu we-amadokhumenti esitifiketi ngemuva kokuthola i-ESE.

Ukucacisa okukodwa engikufaka engxoxweni ngayinye yokuqala: izinombolo zekilasi zilandela umhlangano womndeni we-NF C 17-102 (izinga lama-25 / 45 / 60 μs), futhi i-ΔT eqinisekisiwe ngqo yeyunithi ethile yilokho okushiwo umbiko wayo webhulebhu - umbiko, hhayi ilebula, yilokho okufakwa efayeleni lokuklama elihambisanayo. Uma umhloli wakho wephrojekthi ecela inani, umbiko uyaphendula; igama lemodeli liyikhodi emfushane nje eyisa wonke umuntu emgqeni ofanele wethebula.

Ithini Ifomula Yerediyasi Ngesakhiwo Sakho?

Ifomula ye-NF C 17-102 yomndeni werediyasi, ye-mast emi ngamamitha angu-h ngaphezu kwendawo evikelwe, ingu-R_p= √(2rh − h² + Δ(2r + Δ)), lapho i-r iyirediyasi ye-rolling-sphere yezinga lokuvikela elidingekayo kanti i-Δ iyintuthuko ebangela ukuqhuma evezwe ngamamitha (iklasi lama-25 μs lifaka u-Δ = 25 m, ama-45 μs anikeza u-45 m, kanti ama-60 μs anikeza u-60 m). Izinguquko ezintathu, imiphumela emithathu. Ukuphakamisa i-mast kuphakamisa irediyasi kodwa ngokuncipha kokubuya njengoba i-h isondela ku-r. Ukuqinisa izinga lokuvikela kunciphisa u-r futhi kunciphisa yonke irediyasi kuphrojekthi. Futhi ukuphakamisa ikilasi le-ΔT kunezela ukumbozwa kunoma yikuphi ukuphakama kwe-mast okuhleliwe - okuyi-lever kanye ne-lever okulawulwa ukukhetha kwe-ESE2500/4500/6000. Ngisebenzisa le fomula kuzinombolo zangempela zeklayenti kuzo zonke izingcaphuno,ngobaukusebenzisana kunamandla ngokwanele ukuthi umuzwa wodwa ukhetha njalo imodeli engalungile.

Ikhanda le-air-terminal elihlanganyelwe emndenini we-ESE2500/4500/6000 — idivayisi yokuqalisa ngaphakathi iyahluka ngokwesigaba, futhi umbiko wayo we-ΔT yilokho okumelelwa yinombolo yemodeli.

Ukufanisa Amamodeli Nezigaba Zokwakha: Ithebula Lokukhetha Esilicaphuna Kuwo

Ifomula esandleni, nansi imephu ewusizo esetshenziswa yideski lethu njengokudlulisa imibuzo yokuqala yomakhi - umqondo ofanayo, ocindezelwe etafuleni esicaphuna kulo ngaphambi kokubuyekezwa komdwebo okuningiliziwe.

Qaphela umugqa wokugcina — yiwona abasabalalisi abasibonga ngawo kamuva. Amaphrojekthi okuvuselela afika nokuphakama kwensika sekuvele kuvikelwe yisakhiwo esikhona, uthango noma isineke somklami, futhi kuleyo misebenzi ikilasi lamamodeli yilona kuphela elisele ukuthenga ukumbozwa ngalo.NgobaIfomula ishintshana ngokuphakama ngokumelene ne-ΔT, ukusuka ku-4500 kuya ku-6000 ekuphakameni kwensika eqondile ithola ingxenye ebalulekile yerediyasi - ngokuvamile umehluko phakathi kwensika eyodwa nezimbili. Isifundo esiphambene naso sibalulekile: uma ithebula lithi u-2500 umboza isakhiwo, ukucaphuna u-6000 kuthengisa ngokweqile, futhi sizokutshela kanjalo kwikhotheshini uqobo.

Izinga Lokuvikela Lingena Kuphi Esinqumweni?

Izinga lokuvikelwa liyinguquko ethule osonkontileka abayithatha kalula.I-IEC 62305-1ifaka amazinga okuvikela amane ane-radii ye-rolling-sphere yamamitha angu-20, 30, 45 kanye no-60, futhi izinga livela ekuhlaziyweni kwengozi kwe-I-IEC 62305-3indawo — ukuthi isakhiwo siqukethe ini, ukuthi sivikela bani, nokuthi isiteleka singabiza malini ngemiphumela kunokuba silungiswe. Izinga I liyiklasi eliqinile lezindawo ezinemiphumela ephezulu; Izinga IV lihlanganisa izakhiwo ezijwayelekile. Izinga lingena kufomula yerediyasi ngo-r, ngakho izakhiwo ezimbili ezifanayo ezichazwe emazingeni ahlukene zidinga ukumbozwa okuhlukile kusuka ku-mast efanayo. Ngicela izinga elidingekayo lephrojekthi ngaphambi kokuthi ngicaphune imodeli,ngobaimodeli ehlangabezana neZinga lesi-3 ingashiya isidingo seZinga lesi-2 singamboziwe ekuphakameni okufanayo - futhi "umdwebo oshiwo i-ESE" awulona izinga.

Uma imibhalo yephrojekthi ingasho izinga, phatha lokho njengombuzo okufanele uwuphakamise, hhayi isikhala ongasibeka ephepheni. Ithimba lethu lizobala kusukela ezingeni elishiwo uma unalo bese limaka ukucabangela uma ungenalo; noma ngabe yikuphi inothi lokubala lingena efayeleni kanye nesincomo semodeli, ukuze umeluleki abone isisekelo kunokuba athathe imodeli ngokholo.

Itheminali ye-ESE yesitayela sekheji evela ebangeni lethu: i-geometry yekhanda iyahlukahluka ngochungechunge, kodwa i-logic yokukhetha — isigaba, ukuphakama, izinga — iyafana emndenini wonke.

Ukuphakama, Unyawo kanye Nokumbozwa Kwesigxobo Esisodwa: Wazi Kanjani Ukuthi Ikhanda Elilodwa Lanele?

Ukuhlolwa kulula futhi akunasihawu: dweba indilinga evikelwe ohlelweni lophahla. Uma irediyasi ebaliwe R_pKusukela endaweni yensika kufinyelela kuwo wonke amakhona onyawo ngomkhawulo, ikhanda elilodwa lanele; uma ikhona liwela ngaphandle, izinketho ziyinsika ende, uhlobo lwemodeli oluphezulu, noma isikhundla sesibili - ngaleyo ndlela yokukhetha ophahleni oluningi lwezentengiselwano oluyisicaba.NgobaAmakhona ahlala ewuphawu oluveziwe, ngicela osonkontileka ububanzi obuyisigamu sophahla, hhayi indawo: ibanga lekhoneni ukusuka esicongweni yinombolo okufanele i-radius iyishaye. Ophahleni olubunjwe ngo-L noma olunezitebhisi ukuhlolwa okufanayo kusebenza ngendawo ngayinye, kanti i-hybrid enezindawo zomoya ezivamile kumabhulokhi esibili iyimpendulo efanele - ukuqhathanisa kwethuIzinduku ze-ESE ngokumelene nezinduku zendabuko zikaFranklinihlanganisa lapho ubuchwepheshe ngabunye buthola indawo yabo.

Izikhumbuzo ezimbili ezisebenzayo ezivela emisebenzini eyahamba kahle. Okokuqala, umoya nokulungisa: insika ende enekhanda phezulu iyisitsha somoya esivunguvungwini, ngakho-ke ukwakheka kwensika, ukulungiswa kwesisekelo kanye nesilinganiso somoya wekhanda kufanele kube yinto efanayo nesibalo serediyasi — ama-terminal ethu omoya akhelwe isevisi eveziwe, kodwa insika iyinto yesakhiwo umfaki wakho anayo. Okwesibili, umhlaba: wonke ama-joule ikhanda eliwabambayo asahamba phansi kuma-conductor aye endaweni yokumisa umhlaba okumele ihlangabezane nomgomo wayo wokumelana, njengezingxenye nezidingo zomhlaba.I-IEC 62561-2cabanga. Imodeli ekhethwe kahle kakhulu emhlabeni ohlulekile uhlelo oluhlulekile; umugqa wethu wezinto zokwakha ukhona ngendlela yokuthi izingxenye zombili zochungechunge zivela kumhlinzeki oyedwa ophendulayo.

Ingxenye yobubanzi bethu be-air-terminal: Amakhanda e-ESE nezinduku ezivamile zithunyelwa eceleni, futhi imiklamo exubile iyimiphumela evamile yokuhlolwa kwe-radius kunokuba kube yinto ehlukile.

Yimaphi Amadokhumenti Okufanele Afike Nemodeli Ngayinye?

Noma ngabe imodeli ifika kumdwebo, ngitshela abathengi ukuthi bacele isethi efanayo yephepha, ngoba isimangalo sekilasi sihle kuphela njengefayela laso:umbiko wokuhlola wokuqalisa kusengaphambili (ΔT)kusuka elabhorethri egunyaziwe ene-high voltage, elinganiswa ngeI-IEC 62305-3kanye nephrothokholi yokuhlola ye-NF C 17-102; isimemezelo sezinto zokwakha kanye ne-plating sekhanda; incwadi yokufaka ene-torque kanye nemininingwane yokufaka; kanye nezitifiketi zohlobo lokuhlola ze-down-conductor kanye ne-termination hardware eziqeda uhlelo ngaphansiI-IEC 62561-2Ngokwami, umhlinzeki othumela zonke lezi zinto ezine ngaphandle kokuxoshwa umhlinzeki okuhlolwa kwakhe kwemboni kuhamba kahle.

Ngobaisibalo se-ΔT yinombolo eyodwa ehlukanisa amamodeli amathathu, angikaze ngamukele inani lencwajana ngokwalo — umbiko wokuhlola ogunyaziwe, hhayi ilebula, yilokho okufakwa kufayela lokuklama elihambisanayo.

imibuzo ejwayelekile ukubuzwa
