Foni yomwe ndimalandira nthawi zambiri kuchokera kwa akatswiri amagetsi imakhala motere: “Chithunzicho chikunena kuti ESE arrester. Ndi mtundu uti — 2500, 4500 kapena 6000?” Yankho silili lokonda; ndi kuwerengera, ndipo nambala ya chitsanzo ndiyo yoyamba kulowetsedwa. Mu banja la chinthuchi nambala imalemba kalasi yoyambitsa patsogolo ya mutu — mtengo wa ΔT, m'makalasi a 25 / 45 / 60 microsecond, yomwe fomula ya NF C 17-102 radius imasandulika mamita a chophimba chotetezedwa. ESE2500 ndi mutu wocheperako wa kutalika kochepa ndi mapazi olimba; ESE4500 ndi gulu lapakati lomwe limaphimba nyumba zambiri zamalonda; ESE6000 ndi mutu wautali wa masts ataliatali, mapazi otakata kapena milingo yolimba yotetezera. Sankhani mwalamulo ndipo musiye ngodya zakutali za denga zikuwonekera kapena mugwiritse ntchito ndalama zambiri pa chophimba chomwe nyumbayo singagwiritse ntchito. Bukuli limakupatsani njira yosankha momwe desiki yathu yotumizira zinthu imagwirira ntchito: tanthauzo la nambala, momwe njira yolumikizirana imasinthira kukhala yophimba, tebulo la chitsanzo ndi kapangidwe, ndi chowerengera chomwe mungayendetsere pogwiritsa ntchito ziwerengero zanu za polojekiti.

Nambala ya Chitsanzo Ndi Chodziwikiratu: Kodi 2500, 4500 ndi 6000 Amalemba Chiyani Kwenikweni?

Ogula nthawi zina amaganiza kuti manambala ndi a magawo otsatsa — abwino, abwino, abwino kwambiri. Siwo; ndi makalasi aukadaulo. Nambala imatsata ubwino wa nthawi yoyambitsa mutu ΔT: kuchuluka kwa ma microseconds angati mutu usanatulutse ndodo yowunikira yomwe imayambitsa kukwera kwake, yoyesedwa mu labotale yamagetsi apamwamba.ChifukwaChigawo chotetezedwa chimakula mwachindunji ndi kupita patsogolo kumeneko, nambala ya chitsanzo ndi kalasi ya radius. Ichi ndichifukwa chake lipoti la mayeso a ΔT ndi lofunika kwambiri kuposa chithunzi cha kabukhu: mitu iwiri yomwe imawoneka yofanana ikhoza kukhala yosiyana ndi kalasi, ndipo kalasiyo ndi yomwe kuwerengera kwanu kwa coverage kumagwiritsa ntchito. Tikatchula chitsanzo, kalasi ya ΔT ndi zikalata zake zoyeserera zimayendera limodzi ndi mtengo, ndipo ndikulangiza kontrakitala aliyense kuti apemphe chimodzimodzi kwa wogulitsa aliyense - chizolowezicho chafotokozedwa mu bukhu lathu lazikalata zotsimikizira zomwe zili kumbuyo kwa ESE sourcing.

Kufotokozera kumodzi komwe ndimawonjezera pa zokambirana zonse zoyambirira: manambala a kalasi amatsatira mwambo wa banja wa NF C 17-102 (magawo 25 / 45 / 60 μs), ndipo ΔT yotsimikizika yeniyeni ya gawo linalake ndi chilichonse chomwe lipoti lake la labotale likunena - lipotilo, osati chizindikiro, ndi lomwe limayikidwa mu fayilo yokonza yogwirizana. Ngati woyang'anira polojekiti yanu akufunsani mtengo wake, lipotilo limayankha; dzina la chitsanzo ndi khodi yayifupi yomwe imafikitsa aliyense pamzere woyenera wa tebulo.

Kodi Radius Formula Imati Chiyani Ponena za Nyumba Yanu?

Fomula ya NF C 17-102 ya radius ya banja, ya mast yoyima mamita h pamwamba pa malo otetezedwa, ndi R_p= √(2rh − h² + Δ(2r + Δ)), komwe r ndi radius yozungulira ya mulingo wofunikira wa chitetezo ndipo Δ ndiye kupita patsogolo koyambitsa komwe kumawonetsedwa mu mamita (kalasi ya 25 μs imathandizira Δ = 25 m, 45 μs imapereka 45 m, ndipo 60 μs imapereka 60 m). Zosintha zitatu, zotsatira zitatu. Kukweza mast kumakweza radius koma ndi kuchepa kwa kubwerera pamene h ikuyandikira r. Kulimbitsa mulingo woteteza kumachepa r ndikuchepetsa radius iliyonse mu projekiti. Ndipo kukweza kalasi ya ΔT kumawonjezera kuphimba kutalika kulikonse kwa mast - komwe ndiko komwe ESE2500/4500/6000 imalamulira. Ndimayendetsa fomula iyi pa manambala enieni a kasitomala mu quotation iliyonse,chifukwaKuyanjana kwa zinthu kumakhala kolimba mokwanira kotero kuti chidziwitso chokha chimasankha chitsanzo cholakwika nthawi zonse.

Mutu wa air-terminal womwe umagawidwa m'banja la ESE2500/4500/6000 — chipangizo choyatsira mkati chimasiyana malinga ndi gulu, ndipo lipoti lake la ΔT ndilo lomwe nambala ya chitsanzo imayimira.

Kodi Chitetezo Chimalowa Kuti Pachisankho?

Chitetezo ndi chosinthasintha chete chomwe makontrakitala amachinyalanyaza.IEC 62305-1Ili ndi mafelemu anayi a chitetezo okhala ndi ma radii ozungulira a mamita 20, 30, 45 ndi 60, ndipo mulingowo umachokera ku kusanthula kwa zoopsa zaIEC 62305-3gawo — zomwe nyumbayo ili, omwe amabisala, ndi zomwe kugunda kungapangitse kuti pakhale zotsatirapo m'malo mokonza. Gawo I ndi gulu lokhwima la malo okhala ndi zotsatirapo zazikulu; Gawo IV limaphimba nyumba wamba. Gawo limalowa mu radius formula kudzera mu r, kotero nyumba ziwiri zofanana zomwe zatchulidwa pamlingo wosiyana zimafunikira kuphimba kosiyana kuchokera ku mast yomweyo.

Ngati zolemba za polojekitiyi sizikunena mulingo, tengani zimenezo ngati funso loti mufunse, osati kungolemba mpata. Gulu lathu lidzawerengera kuchokera pa mulingo womwe watchulidwa pamene muli ndi umodzi ndipo lidzalemba chizindikiro pamene mulibe; njira iliyonse, cholembera chowerengera chidzaikidwa mufayilo limodzi ndi malangizo a chitsanzo, kuti mlangizi athe kuona maziko m'malo motengera chitsanzocho pa chikhulupiriro.

Ma terminal a ESE ofanana ndi khola ochokera kumadera athu: mawonekedwe a mutu amasiyana malinga ndi mndandanda, koma mfundo yosankha — kalasi, kutalika, mulingo — ndi yofanana m'banja lonse.

Kutalika, Mapazi ndi Kuphimba Mtanda Umodzi: Kodi Mukudziwa Bwanji Kuti Mutu Umodzi Ndi Wokwanira?

Mayesowa ndi osavuta komanso opanda chifundo: jambulani bwalo lotetezedwa pa pulani ya denga. Ngati radius yowerengedwa R_pKuchokera pamalo a mlongoti kufika pa ngodya iliyonse ya phazi ndi malire, mutu umodzi ndi wokwanira; ngati ngodya yagwa kunja, zosankha ndi mlongoti wautali, kalasi yapamwamba, kapena malo achiwiri - motsatira zomwe amakonda pa denga lanyumba zambiri zathyathyathya.ChifukwaMakona nthawi zonse amakhala ngati mawonekedwe owonekera, ndimafunsa akatswiri opanga madenga kuti apeze theka la m'lifupi la denga, osati dera: mtunda wa ngodya kuchokera ku mzati ndi nambala yomwe radius iyenera kupambana.
