Me pēhea te whakarite tika i te rahi o ngā taputapu tiaki ngaru?
Me pēhea te whakarite tika i te rahi Ngā Pūrere Ārai Pupuhi?
I parai ahau i tētahi whata PLC $20,000 nā te mea i whiriwhiria e au te mea hē SPD.
Ka inehia e au ia SPD mā te whakataurite i tōna Uc ki te ngaohiko pūnaha, tōna Imax ki te ngaru kino rawa atu, me tōna Tae atu ki te ātete o te taputapu; kātahi ka tirohia e au ngā tau e toru i roto i te ripanga kotahi.
Pānui tonu, ā, māku e whakaatu ki a koe te ripanga kia kore ai koe e mahi anō i taku hapa.
He aha te Tika SPD He mea nui te rahi?
I ngaro i ahau tētahi rā whakaputa katoa i te pahūtanga o tētahi SPD 40 kA i roto i tētahi tupuhi 100 kA.
Ki te iti rawa te SPD ka mura; ki te nui rawa ka nui rawa te utu; mā te rahi tika ka noho pūmau te rārangi mahi, ka marino hoki te kaikaute.
Te Utu Tuturu o ngā SPD Rahi-iti
Kāore ngā SPD iti nei e rahua noa; ka rahua kinotia rātou.
I kite ahau i tētahi e pahū ana, e pupuhi ana te kirihou rewa ki runga i te pae.
I mutu te tipu mō ngā hāora 14 i a mātou e whakawhiti ana i te panera katoa.
Ko te pire tūturu he $18,000 i roto i te putanga ngaro, ehara i te $200 SPD.
Te Utu Huna o ngā SPD Nui Rawa
He āhua haumaru ngā SPD nunui rawa, engari he nui ake te utu i te tīmatanga, ā, ka nui ake te pūngao e tukuna ana.
He teitei ake te Runga o te waeine 200 kA i runga i te ratonga 20 kA.
Ka taea e taua 200 V tāpiri te whakamate i te tāuru PLC 1,200 V.
E rua āu utu: kotahi mō te pouaka nui, kotahi mō te kāri parai.
Te Whakatau i te "Rahi Tika" i roto i ngā Pātai e Toru
- He aha te ngaru nui rawa atu ka taea te tae mai ki konei?
- He aha te ngaohiko ka taea e taku kawenga te ora?
- Ko ēhea ngā tau pepa raraunga SPD e kapi ana i ngā mea e rua?
Ki te taea e au te whakautu i ēnei e toru, he tika te rahi.
Ngā Whakatauranga Matua o te SPD: Uc, Imax, Iimp, me Up
I whakaranua e au a Imax me Iimp; i tētahi rā i rahua taku papatohu e te kaitirotiro.
Ka whiriwhiria e au a Uc ≥ ngā ngaohiko pūnaha, Imax ≥ te ngaru ā-rohe, Iimp ≥ te akomanga uira, me te Up ≤ 80% o te ātete o ngā taputapu; ka tuhia e au ngā tau e whā i te rarangi kotahi i mua i taku hoko.
Uc – Te Ngaohiko ka taea e te SPD te Noho Tonu
Ko Uc te tau pūtake.
Ki te iti rawa te tīpakonga, ka huri te SPD hei poto.
Ki te teitei rawa te tīpakonga, ka piki ake te taumata tiaki.
Ka whakamahia e au te Ripanga 1 hei taurite i te ngaohiko pūnaha ki te Uc iti rawa.
| PūnahaNgaohiko(LL) | MinimumUc |
| Wāhanga wehewehe 120/240 V | 150V |
| 208 Y/120 V | 150V |
| 240 V te awaawa | 255 V |
| 380 Y/220 V | 255 V |
| 480 Y/277 V | 320V |
Imax – Te Ngaru Nui Ka Taea e te SPD te Whakaeke Kotahi
He tau kotahi te pānga o Imax.
Ka titiro ahau ki te mahere kiato o te uira ā-rohe.
Mena e whakaatu ana te mahere i te 8 uira mō ia km², ka whakatauria e au he 100 kA.
Mena e whakaatu ana te mahere i ngā uira e 4, ka whakatauria e au he 60 kA.
Ahakoa i roto i te rohe iti te mōrearea, kāore au e heke iho i te 40 kA.
Iimp – Te Tānga Akomanga Uira
Ka whakamatautauria a Iimp ki te ngaru 10/350 µs.
E 25 kA mō ia pou te hiahia mō te Akomanga I.
E hiahia ana te Akomanga II ki te 12.5 kA.
Mena he tokotoko uira tā te ratonga, ka tāpirihia e au te Akomanga I ki te mita.
Runga – Te Ngaohiko e Toe ana mō te Kawenga
Ko te mea e kitea ana e taku PLC kei runga.
Ka tangohia e au te mea iti rawa e taea ana e te tahua, engari ka puritia e au i raro i te 80% o te taumata hiahia mō ngā taputapu.
Ka whiwhi te PLC 2,000 V i tētahi SPD me te Up ≤ 1,600 V.
Mena he roa te taura, ka whakaitihia e au ki te 1,200 V nā te mea ka tāpirihia e te waea he 200 V māna ake.
He Aratohu Hipanga-i-te-Hipanga mō te Whakarahi i tō Pūrere Tiaki Ngaru
Ka whakarārangihia e au ia SPD ki runga i te pepa A4 kotahi.
E rima ngā pouaka ka whakakīia e au: ngā ngaohiko pūnaha, te taumata mura, te roa o te taura, te ātete kawenga, me te tahua; kātahi ka pānuihia e au te waehere tauira mai i te pou whakamutunga o taku ripanga rapu.
Hipanga 1 – Tuhia te Ngaohiko me te Whirihoranga Pūnaha
Ka tīmata ahau me te pereti ingoa i runga i te pūwāhi matua.
Ka tuhituhi ahau: 480 Y/277 V, 3-wāhanga, 4-waea.
E whakaatu ana tēnā ko Uc ≥ 320 V mai i te Ripanga 1.
Hipanga 2 – Kimihia te Kiato o te Uira
Ka whakatuwherahia e au te mapi NASA kore utu ka pāwhiri i taku tipu.
E ai ki te mapi e 6 ngā uira mō ia km².
Ka neke ahau ki te Tēpu 2.
| Te Matotoru o te Uira | Imax iti rawa mō ia aratau | Akomanga |
| 0–2 | 40 kA | II |
| 3–5 | 60 kA | II |
| 6–10 | 100 kA | ahau |
| >10 | 160 AD | ahau |
Ka whiriwhiria e au te 100 kA me te Akomanga I.
Hipanga 3 – Ine i te Roa o te Taura mai i te Ratonga ki te Utaina
Ka hikoi au i te ara me te rīpene.
Mena he roa ake te oma i te 30 m, ka tāpirihia e au tētahi atu SPD ki te papa-iti.
Ka tāpirihia e ngā taura roa te 10 V o te kōhao pupuhi i ia mita.
Hipanga 4 – Tirohia te Ātete o ngā Taputapu
Ka whakatuwherahia e au te pukapuka ā-ringa PLC.
E mea ana "ka taea te tu atu i te 1,500 V te ātete ki te nekehanga".
Ka whakareatia e au ki te 0.8, ā, ka whakatūria he ≤ 1,200 V.
Hipanga 5 – Kōwhiria te Tauira me te Utu
Ka whakatuwherahia e au taku pepa o roto e whakaaturia ana i te Ripanga 3.
| Tau Wāhanga | Uc | Imax | Iimp | Ki runga | Utu1kpcs |
| LKX-480-40 | 320V | 40 kA | 12.5 kA | 1,400V | $18 |
| LKX-480-100 | 320V | 100 kA | 25 kA | 1,100V | $28 |
| LKX-480-160 | 320V | 160 kA | 50 kA | 900V | $42 |
E ōrite ana te rarangi waenga ki ngā pouaka katoa, nō reira i whiriwhiria ai e au te LKX-480-100.
Hipanga 6 – Tukua te Ota me te Tohu i te Rā
Ka tāpirihia e au te rā tuku ki taku maramataka.
I whakatakotohia hoki e au he whakaoho whakawhiti rima tau nā te mea ka pakeke haere ngā SPD pai.
Kōwhiringa SPD mō ngā Taupānga Rerekē: Whare Noho, Arumoni, me te Ahumahi
E noho ana ahau i tētahi whare 120 V, he toa 480 V tōku, ā, kei te whakahaere ahau i tētahi tipu hiko 22 kV.
Ka whiriwhiria e au te 20 kA Momo 3 mō taku pouaka whakamātao, 100 kA Momo 1+2 mō taku toa, me te 160 kA Momo 1+2+3 mō te tipu; he waitohu kotahi, he tēpu tirotiro kotahi, he rarangi rerekē.
Whare Noho – Kia Māmā, Kia Utu iti hoki
Ka kitea e ngā whare te 40 kA te teitei rawa.
Kotahi te Momo 2 e whakamahia ana e au i te panera, me tētahi Momo 3 i te pouaka whakaata.
Ko te tapeke o te utu kei raro i te $60.
Ka moe tonu ahau ina pā mai te awha.
Arumoni – Taupokina te Utaina Whakaranu
He rama, he HVAC, me ngā kaipānui kāri kei roto i ngā toa hokohoko.
I whakatakotoria e au te Momo 1 ki te ratonga, te Momo 2 ki ia papa-iti, me te Momo 3 ki te POS.
Kei te pupuri tonu ahau i te whānau Up kotahi, kia honoa ai ngā āhua o ngā ngaru, kaua e whawhai.
Ahumahi – Tatauhia ngā Porowhita me ngā Mōta
Ka whakahokia te 1,500 V e ngā motuka ki te rārangi ina whakawetohia.
Ka tāpirihia e au he RC snubber me te SPD me te tawhē 200 V ki Runga.
Ka whakamahia hoki e au ngā waeine DIN-rail kia taea ai e au te whakawhiti ora tonu; he nui ake te utu mō te wā kore mahi i te wāhanga.
Ngā Rohe Motuhake – Ngā Mea Mōrearea me Ngā Mea Hauora
I ngā wāhi pahū o te Rohe 2, ka whiriwhiria e au ngā SPD kua whakakīia ki roto i ngā kākano kore-mura.
I ngā hōhipera ka whakamahia e au ngā tātari taumata hauora me te iti iho i te 0.5 mA te turuturu ki te whenua.
He rite tonu te ripanga; ko te whakamutunga anake e rerekē ana.
Whakamutunga
Ka whakarārangihia e au ngā SPD me ngā tau e whā: Uc, Imax, Iimp, Up.
Whakatuwheratia ngā ripanga, whakakīia ngā pouaka, tīpakohia te rarangi, ā, e kore rawa koe e hoko i te pouaka hē anō.
Tukuna mai te ingoa o tō panera, ā, ka tukuna atu e au te wāhanga tika āpōpō.
