Ko te waea e tino whiwhihia ana e au mai i ngā kaihanga hiko e penei ana: "Kei te tuhi te tohu ESE arrester. Ko tēhea tauira — 2500, 4500, 6000 rānei?" Ehara te whakautu i te mea whiriwhiri; he tataunga noa iho, ā, ko te tau tauira te whakaurunga tuatahi. I roto i tēnei whānau hua, ko te tau e tohu ana i te akomanga whakaoho-whakamua o te pane — te uara ΔT, i roto i ngā akomanga 25/45/60 microsecond, e hurihia ana e te tātai radius NF C 17-102 hei mita o te kapinga tiaki. Ko te ESE2500 te pane mahi-kiato mō ngā teitei iti me ngā tapuwae kikī; ko te ESE4500 te akomanga waenga e kapi ana i te nuinga o ngā whare arumoni; ko te ESE6000 te pane toronga-roa mō ngā pou teitei, ngā tapuwae whānui, ngā taumata tiaki pakari ake rānei. Kōwhiria mā te ture matua, ā, ka waiho e koe ngā kokonga tawhiti o te tuanui kia kitea, ka nui rawa rānei te whakapau moni ki te kapinga kāore e taea e te whare te whakamahi. Mā tēnei aratohu ka hoatu ki a koe te arorau kōwhiringa e rite ana ki te whakahaere a tā mātou tēpu kaweake: te tikanga o te tau, me pēhea te hurihanga e te tātai pūtoro hei taupoki, he ripanga tauira-mā-te-whare-akomanga, me te tātaitai ka taea e koe te whakahaere i runga i ō ake whika kaupapa.

Ko te Tau Tauira te Whakatakotoranga: He aha te mea e Whakawaeherehia ana e 2500, 4500 me te 6000

I ētahi wā ka whakaaro ngā kaihoko he taumata hokohoko ngā tau — pai, pai ake, pai rawa atu. Ehara i te mea pērā; he akomanga hangarau. Ka whai te tau i te painga wā whakaoho o te pane ΔT: e hia ngā maikorohekona i mua i te whakarewatanga o te pane i tana awa ki runga i te tokotoko tohutoro kore mahi, i inehia i roto i te taiwhanga ngaohiko teitei.Nā te meaKa tipu tika te pūtoro tiaki me taua ahunga whakamua, ko te tau tauira he akomanga pūtoro. Koinei hoki te take he nui ake te hiranga o te pūrongo whakamātautau ΔT i te whakaahua o te rarangi pukapuka: e rua ngā pane e āhua ōrite ana, ā, ko te akomanga te mea e whakamahia ana e tō tataunga kapinga. Ina whakahuahia e mātou he tauira, ka haere tahi te akomanga ΔT me ōna tuhinga whakamātautau me te whakahua, ā, ka tohutohu ahau ki ia kaiwhakatū kia tono i te mea kotahi mai i tētahi kaiwhakarato - kua whakamāramahia te tikanga i roto i tā mātou aratohu kingā tuhinga whakamana kei muri i te pūtake ESE.

Kotahi te whakamārama ka tāpirihia e au ki ia kōrero tuatahi: ko ngā tau akomanga e whai ana i te tikanga whānau NF C 17-102 (ngā taumata 25 / 45 / 60 μs), ā, ko te ΔT kua whakamanahia tika o tētahi waeine kua hoatu ko te mea e kīia ana e tana pūrongo taiwhanga - ko te pūrongo, ehara i te tapanga, te mea e whakaurua ana ki roto i tētahi kōnae hoahoa e tutuki ana i ngā whakaritenga. Mena ka pātaihia e tō kaitātari kaupapa te uara, ka whakautua e te pūrongo; ko te ingoa tauira he waehere poto noa iho e kawe ana i te katoa ki te rarangi matau o te ripanga.

He aha te kī a te Tātai Radius mō tō whare?

Ko te tātai pūtoro whānau NF C 17-102, mō te pou e tū ana he h mita i runga ake i te mata tiakina, ko R_p= √(2rh − h² + Δ(2r + Δ)), ko r te radius porowhita hurihuri mō te taumata tiaki e hiahiatia ana, ā, ko Δ te nekehanga whakaoho e whakaatuhia ana i roto i ngā mita (ko te akomanga 25 μs e whai wāhi ana ki a Δ = 25 m, ko te 45 μs ka homai he 45 m, ā, ko te 60 μs ka homai he 60 m). E toru ngā taurangi, e toru ngā hua. Mā te whakaara ake i te pou ka ara ake te radius engari ka heke haere ngā hokinga mai i te whakatata atu o h ki a r. Mā te whakawhāiti i te taumata tiaki ka whakaiti i a r, ka whakaiti hoki i ia radius i roto i te kaupapa. Ā, mā te whakaara ake i te akomanga ΔT ka tāpirihia he kapinga i tētahi teitei pou pumau - koinei tonu te rīwhi e whakahaeretia ana e te kōwhiringa ESE2500/4500/6000. Ka whakahaerehia e au tēnei tātai i runga i ngā tau tūturu a te kiritaki i roto i ia kōrero,nā te meaHe kaha rawa ngā taunekeneke, ā, mā te pūmanawa anake e whiriwhiri te tauira hē.

Ko te pane o te taunga hau e whakamahia whānuitia ana puta noa i te whānau ESE2500/4500/6000 — he rerekē te taputapu whakaoho i roto i ia akomanga, ā, ko tana pūrongo ΔT te tohu o te tau tauira.

Te Whakataurite i ngā Tauira ki ngā Akomanga Hanga: Te Ripanga Kōwhiringa i Tukuna Mai e Mātou

Kei te ringa te tauira, anei te mahere mahi e whakamahia ana e tā mātou tēpu hei huarahi tuatahi ki ngā patai a te kaikānata — ko te arorau kotahi, i whakaurua ki te ripanga i whakahuatia e mātou i mua i te arotake tuhi taipitopito.

Kia mōhio ki te rarangi whakamutunga — koinei te mea e mihi mai ai ngā kaituku mō muri mai. Ka tae mai ngā kaupapa whakahou me te teitei o te pou kua oti kē te whakawhāiti e te hanganga o nāianei, te parepare, te manawanui rānei o te kaihoahoa, ā, i roto i aua mahi, ko te momo tauira anake te taurangi e toe ana hei hoko hipoki.Nā te meaKa whakawhitihia te teitei e te tātai ki te ΔT, mā te neke mai i te 4500 ki te 6000 i te teitei o te pou kua whakaritea ka whakahokia mai he poro nui o te radius - he maha ngā wā ko te rerekētanga i waenga i te pou kotahi me te pou e rua. He mea nui anō hoki te tikanga whakamuri: ki te mea kei te ripanga he 2500 e kapi ana i te whare, he hoko nui rawa te whakahua i te 6000, ā, mā mātou e kī atu ki a koe i runga i te whakahua tonu.

Kei hea te Taumata Tiakitanga e uru atu ai ki te Whakataunga?

Ko te taumata tiaki te taurangi puku e whakaititia ana e ngā kaimahi kirimana.IEC 62305-1e wha ngā taumata tiaki e anga ana me ngā radius porowhita hurihuri o te 20, 30, 45 me te 60 mita, ā, ko te taumata i ahu mai i te tātaritanga mōrearea oIEC 62305-3rohe — ngā mea kei roto i te whare, ko wai e noho ana, me te utu mō ngā hua o te patu, kaua mō ngā whakatikatika. Ko te Taumata I te akomanga tino pakari mō ngā whare whai hua nui; ko te Taumata IV e kapi ana i ngā hanganga noa. Ka uru te taumata ki te tātai radius mā r, nō reira e rua ngā whare ōrite kua tohua i ngā taumata rerekē me rerekē te hipoki mai i te pou kotahi. Ka pātai atu ahau mō te taumata e hiahiatia ana mō te kaupapa i mua i taku whakahua i tētahi tauira,nā te meaka taea e te tauira e tutuki ana i te Taumata III te waiho i te whakaritenga Taumata II kia takoto kau ana i te teitei kotahi — ā, "ko te tuhi i kīia ko te ESE" ehara i te taumata.

Ki te kore e whakahuatia he taumata i roto i ngā tuhinga kaupapa, me whakaaro he pātai hei whakaara ake, kaua hei āputa hei tāpiri. Ka tatau tā mātou tīma mai i te taumata kua tohua ina kei a koe tētahi, ā, ka tohua te whakaaro ina kāore; ahakoa pēhea, ka whakaurua te tuhipoka tatau ki roto i te kōnae me te taunakitanga tauira, kia kite ai te kaitohutohu i te pūtake, kaua e whakawhirinaki ki te tauira.

He momo kāpeka ESE tēnei mai i tā mātou awhe: he rerekē te āhua o te pane i runga i te raupapa, engari he ōrite te arorau kōwhiringa — te akomanga, te teitei, te taumata — puta noa i te whānau.

Te Teitei, te Tapuwae me te Taupoki Kotahi-Rārangi: Me pēhea koe e mōhio ai he rawaka te kotahi te upoko?

He māmā noa iho te whakamātautau, ā, he nanakia: tuhia te porowhita tiakina ki runga i te mahere o te tuanui. Mena ko te radius R kua tatauhia_pmai i te tūranga o te pou ka tae ki ngā kokonga katoa o te tapuwae me te tawhā, kotahi te upoko e ranea ana; ki te taka tetahi kokonga ki waho, ko ngā kōwhiringa he pou teitei ake, he tauira teitei ake, he tūranga tuarua rānei — i taua raupapa e pai ana mō te nuinga o ngā tuanui arumoni papatahi.Nā te meaKo ngā kokonga he āhuahanga e kitea ana i ngā wā katoa, ka pātai atu ahau ki ngā kaimahi kirimana mō te haurua-whānui o te tuanui, ehara i te horahanga: ko te tawhiti o te kokonga mai i te pou ko te tau me eke e te radius. I runga i ngā tuanui āhua-L, i ngā tuanui arawhata rānei, ka oma te whakamātautau kotahi mō ia rohe, ā, he whakautu tika te ranu me ngā taunga hau tuku iho i runga i ngā poraka tuarua — ko tā mātou whakataurite iESE me ngā tokotoko Franklin tuku ihoe kapi ana i te wā e whiwhi ai ia hangarau i tōna tūranga.

E rua ngā whakamaumaharatanga whai hua mai i ngā mahi i pai te haere. Tuatahi, te hau me te whakatika: he pou teitei me te pane i te tihi he cantilever i roto i te tupuhi, nō reira ko te hoahoa o te pou, te whakatika turanga me te whakatauranga hau o te pane me uru ki te tuku kotahi me te tatau radius - kua hangaia ā mātou taunga hau mō te ratonga kua kitea, engari he taonga hanganga te pou nā tō kaiwhakauru. Tuarua, ko te whenua: ko ia joule e hopukia ana e te pane ka haere tonu ki raro i ngā kaiarataki ki roto i te pito whenua me tutuki i tana whāinga ātete, i te mea ko ngā whakaritenga wāhanga me te whenua oIEC 62561-2whakaaroaro. Ko te tauira tino pai rawa atu i runga i te whenua pakaru ko te pūnaha pakaru; kei te tū tika tā mātou raina rauemi whenua kia puta mai ai ngā haurua e rua o te mekameka i te kaiwhakarato kotahi e whai kawenga ana.

Ko tētahi wāhanga o ā mātou awhe taunga rererangi: Ka tukuna taha ngā pane ESE me ngā tokotoko tuku iho, ā, he hua noa iho ngā hoahoa whakauru o te whakamātautau pūtoro, ehara i te mea rerekē.

Ko ēhea ngā tuhinga me haere tahi me ia tauira?

Ahakoa te tauira e tau ana ki te tuhi, ka kī atu ahau ki ngā kaihoko kia tono mō te huinga pepa kotahi, nā te mea ko te kereme akomanga anake te mea e pai ana ki tana kōnae: tepūrongo whakamātautau whakaoho-whakamua (ΔT)mai i tētahi taiwhanga ngaohiko teitei whaimana, i inehia mō iaIEC 62305-3me te kawa whakamātautau NF C 17-102; te whakapuakitanga rauemi me te whakakikorua mō te pane; te pukapuka tāutanga me ngā taipitopito taipana me te whakairinga; me ngā tiwhikete whakamātautau-momo mō te taputapu kawe-iho me te whakamutu e whakaoti ana i te pūnaha i raro iIEC 62561-2E ai ki aku wheako, ko te kaiwhakarato e tuku ana i ngā mea e whā me te kore e whaia, he kaiwhakarato ia e pai ana te haere o ana arotake wheketere.

Nā te meaKo te āhua ΔT te tau kotahi e wehewehe ana i ngā tauira e toru, kāore au e whakaae ki tētahi uara pukapuka takitahi — ko te pūrongo whakamātautau kua whakamanahia, ehara i te tapanga, te mea e whakaurua ana ki roto i tētahi kōnae hoahoa e tutuki ana i ngā whakaritenga.
