He aha te mahi a te Kaitiaki Ngaru?

Kei te maumahara tonu ahau ki te rā i pau ai te hawhe miriona tāra i taku kiritaki i te pānga o te uira kotahi. Kotahi te uira, ā, ka huri katoa tana whata PLC hei konganuku para utu nui.

Ka tahuri ke, ka mimiti rānei te parenga ngaru i ngā pikinga ngaohiko morearea i mua i te taenga atu ki ngā taputapu tairongo, kia noho haumaru ai ō mīhini, ō raraunga me ō hua. Kua mātakitaki ahau i tēnei taputapu māmā e whakaora ana i ngā raina whakaputa katoa i Haina, Tiamana, me te UK.

Ki te hoko koe ngā taputapu tiaki-arahiko Hei oranga mōu, e mōhio ana koe ki ngā mea nui o te utu. Pānui tonu, ā, māku e whakaatu ki a koe me pēhea te whakaiti i te utu katoa o te mana whakahaere me te kore e whakaiti i te tiakitanga.

Te Mārama ki a Ste Tiakitanga o te akiaki i roto i ngā Taiao Ahumahi me ngā Taiao Tauhokohoko?

I hikoi ahau i roto i tētahi wheketere wāhanga waka 24-hāora i Wenzhou i te marama kua taha ake nei. I kī mai te kaiwhakahaere ko te utu mō ia haora o te wā kore mahi he 38,000 USD. Ka taea e te pikinga kotahi te hanga i taua wā kore mahi i roto i te 3 nanohekona.

Ka ārai te parenga ngaru ahumahi i ngā ngaohiko nui e hangaia ana e te uira, te whakawhiti whatunga, me ngā Puku Auautanga Rerekē kei tae atu ki ngā PLC, ngā tūmau, me ngā karetao. Ka hoahoa au i ēnei pūnaha mō ngā raina motuka Tiamana me ngā pokapū raraunga o Peretānia i ia wiki.

Tērā pea koe e whakaaro he mura noa iho te ngaru hiko. Ko te pono he mea mōrearea ake, he iti ake hoki te utu ki te aukati i te whakatika.

Nō hea ngā ngaru nui

Ko te uira te pūtake tino haruru, engari ehara i te mea tino noa. He nui ake aku ine i ngā titi mai i roto i te rangi i te mea mai i te rangi. Ka taea e te motuka 100 hp te whakaweto te pana i te 1,800 V ki runga i te pahi kotahi e whāngai ana i tō pūoko. E 50 maikorohekona noa iho te roa o te ngaru, engari he roa ki te wero i te waikura kuaha o te MOSFET. Kua kite ahau i tēnei i roto i tētahi wheketere takai Vietnamese. I tāpirihia e mātou he parenga Momo 2 40 kA ki te papa-iti, ā, i heke te reiti rahunga mai i te 3 papa ia marama ki te kore i roto i ngā marama 14.

Kia pēhea te nui o te mōrearea?

I tono ahau ki taku tīma kia tangohia ngā raraunga mai i ngā wheketere e 200 e mahi ana mātou. I kitea e mātou he 7.4 ngā kati kore i whakaritea i te tau i tētahi wāhi kāore he parenga ngaru hiko. Ko te toharite o ia kati he 4.2 hāora. Mena ko tō moni whiwhi he 50 mano tāra USD ia rā, ko te 1.5 miriona tāra USD o te pānga i ia tau. Ko te utu mō tētahi parenga wheketere katoa he iti iho i te 0.3% o taua tau. Ko te wā whakahoki utu he 11 rā, ehara i te 11 marama.

Ngā paerewa me tutuki e koe

Ka tukuna e au ki Ūropi, nō reira ko ngā parepare katoa e hokona ana e au he tohu CE me te TÜV. Ka whakamātauhia e mātou kia rite ki te IEC 61643-11. Mena ka kawemai koe ki Tiamana, me whai VDE 0675 anō hoki koe. Ka puritia e au aua kōnae i te reo Ingarihi me te reo Tiamana, kia rite ai mō tō kōpaki tiwhikete. Ka taea e koe te tuku atu ki tō kiritaki whakamutunga i te rā tonu ka whiwhi koe i ngā taonga.

Ngā Mahi Matua o te Kaitiaki Ngaru?

I te hauwhā whakamutunga i āwhina ahau i tētahi kamupene tunu taro Wīwī. I tukuna e rātou tētahi raina hou ki Kanata, ā, i rahua te whakamātautau ngaru tuatahi. I tāpirihia e mātou tā mātou waeine mono-mai, ā, i pai te pūnaha i te ata i muri mai.

Ka kitea e te parenga ngaru te ngaohiko taikaha, ka herea ki te taumata haumaru, kātahi ka tautuhi anō i a ia anō kia haere tonu te mahi whakaputa me te kore e wawaotia ā-ringa.Ka whakamātauria e au ia waeine i runga i tā mātou whakaputa hiko 8/20 µs i mua i tōna wehenga atu i tō mātou tauranga Wenzhou.

Tērā pea ka whakaaro koe he pouaka whakarewa noa iho ngā taputapu ngaru hiko. I roto, e toru ngā wāhanga iti e whakatau ana mēnā ka rere, ka mura rānei tō raina.

Te kanikani e toru ngā wāhanga

E toru ngā taahiraa e whakamāramahia ana e au te mahi. Hipanga 1: ka pā te tuatahi ki te aukati hau. Ka mura i te 600 V ka puta he hiko poto. Hipanga 2: ka mimitihia te kaha nui e te varistor waikura-metara (MOV). Hipanga 3: ka tapahia e te diode TVS te 30 V whakamutunga kia kore ai e kite tō PLC 24 V i te neke atu i te 37 V. Kua tirotirohia e au tēnei i runga i tā mātou pae taiwhanga. Ka mutu te huihuinga katoa i roto i te 9 nanohekona, he tere ake i te tere o tō HMI.

Momotu wera

Ka tawhito haere ngā MOV. Ina rahua tētahi MOV, ka taea te poto, ka mura. Ka tāpirihia e au he fiusi wera kua whakapirihia ki te tinana MOV. I te 142 °C ka tuwhera te fiusi, ā, ka unuhia te MOV mai i waho o te ipurangi. Kei a au ngā whakaahua whakamātautau UL 1449 putanga tuawhā e whakaatu ana i te kore mura i muri i te 30 meneti. Ka pai ki tō kaiinihua ahi taua kōnae.

Whakapā mamao

E hiahia ana ngā tipu nui kia mōhio kua mate te parepare i mua i te ngaru e whai ake nei. Ka tāpirihia e au he hononga kore-pūmanawa. Ka taea e koe te hono atu ki tō SCADA. Ina pakaru te parepare, ka whiwhi tō PLC i te tohu 24 V, ā, ka whakaritea e koe he whakawhiti i te wā e whai ake nei. Kāore he waea waenganui pō, kāore he utanga tere.

He aha te hiranga o te parenga ngaru mō ngā pakihi?

I ngaro i ahau tētahi kiritaki o te UK i te tau 2019. I mahue i a ia ngā kaitiaki hei penapena i te 2,300 USD. I pā mai tētahi awha, ā, i whakangaromia e ia ngā taraiwa 18, ā, i whakakahoretia e tana kaiinihua te kereme. I kati ia i te wheketere i ngā marama e rua i muri mai.

Mā te parenga ngaru ka mau tonu te rere o ngā moni whiwhi, ka mau tonu te mana o ngā pūtāhui, ā, ka mau tonu te ingoa o te waitohu.Kei a au ngā reta mai i ngā kaiwhakahaere pūtea e kī ana i a mātou he toa, ehara i te kaiwhakarato.

Ka taea e koe te whai i te utu mō ia waeine. Ka whaihia e tō CFO te EBITDA. Ka taea e te pikinga kotahi te whakakore i ngā penapena tekau tau.

Ngā utu huna ka warewarehia e koe

Ina pakaru te puku, ka utua e koe te wāhanga, te tohunga hangarau, te kereni, me te puranga ngaro. Ka whakarārangihia e au ēnei ki tētahi pepa māmā mō ia whakatau utu. Ko te utu mō te puku 75 kW he 4,800 USD. Ko te utu mō te kereni he 600 USD. Ko te ngaronga o te puranga he 12,000 USD. Ko te katoa he 17,400 USD. Ko te utu mō taku parepare he 89 USD. He whanoke te pāngarau, engari he pono.

Ngā ture pūtāhui

E rima tau te roa o taku whakamana mō ia parepare, engari mēnā ka whai koe i te IEC 60364-5-53, ā, ka tāuta ki te taha matau. Ki te kore koe e whakamahi i te parepare, ka kore pea tō whakamana OEM i runga i te puku. Kua kite ahau i a Siemens e whakakahore ana i te kereme $25,000 nā te mea kāore he SPD i te pae. I whakapae te kiritaki i a mātou, engari ko tana whiringa te he.

Utu inihua

Kei te mahi tahi ahau me tētahi kaiinihua Tiamana e tuku ana i te 5% hekenga o te piremi mēnā he SPD whaimana kei te tipu i ia taumata. I runga i tētahi kaupapa here 400 mano tāra USD, arā, 20 mano tāra USD e penapenahia ana i ia tau. Ka utua e ngā kaitiaki ā rātou ake i roto i ngā wiki e 6, kātahi ka hanga he hua tūturu mō ngā tau 19 e whai ake nei.

Te Kōwhiri i te Otinga Tiaki Ngaru Tika?

I īmēra mai tētahi kaihoko mai i Milan ki ahau inapo. E toru āna whakatauranga, he rerekē te whakatauranga o nāianei o ia whakatauranga. I pātai ia, "Ko tēhea te mea e ranea ana?" I tukuna atu e au he whakautu kotahi te rārangi ki a ia: "Whakatauritehia te mōrearea, kaua te utu."

Kōwhiria he parepare e ōrite ana ki tō taumata pānga, ki tō ia hapa, ā, kei a ia ngā tiwhikete tika mō tō mākete.Ka whakahaerehia e au tēnei tataunga i runga i tētahi ripanga tātaitai i ia rā mō ngā kaihoko i ngā whenua 11.

Tērā pea ka ngaro koe i waenganui i ngā tapanga Momo 1, Momo 2, me Momo 3. Ka mutu taku ngangau, ka hoatu e au ki a koe ētahi pātai e toru.

Pātai 1: Kei hea te uira?

Ka whakatuwherahia e au a Google Maps, ka tirohia te matotoru o te uira. Mena kei roto tō tipu i te rohe e 4 ngā uira/km²/tau, me whai Momo 1 koe i te tomokanga ratonga. Mena kei raro iho koe i te 0.5 ngā uira, he nui te Momo 2. Kei a au he mapi o te ao me ēnei raraunga. Ka tukuna atu e au he kore utu me ia utu.

Pātai 2: He aha te iahiko poto o tō ara iahiko?

I pānuitia e au te ingoa o tō pūwhakawhiti hiko. Ka homai e te pūwhakawhiti hiko 1,600 kVA te iahiko hapa 35 kA. Me ora taku parepare i tēnā. Ka whiriwhiria e au tētahi waeine me te whakatauranga SCC 50 kA. Ki te hoko koe i tētahi taputapu 15 kA hei penapena 12 USD, ka pahū i te wā o te hapa tuatahi. He whakaahua āku, ā, he kino.

Pātai 3: Me mono atu?

Ko ētahi kaihoko e hiahia ana kia kore he wā whakaweto. Kei te tuku atu ahau i tētahi kātere mono. Ina pakaru te kōwae, ka taea te whakawhiti i roto i te 9 hēkona. Kāore he tīwiri, kāore he waea anō. Ka haere tonu te mahi a te tipu. Ko te utu mō te kōwae tāpiri he 28 USD. Kotahi te whakawhiti ka penapena i te wā whakaweto.

Ngā Auahatanga o te Hangarau Tiaki Ngaru ā-Mārama ā-Ao?

I tū ahau i runga i te atamira o Hannover Messe i te Paenga-whāwhā kua taha ake nei, ā, i whakaaturia e au tētahi ārai mate me te waehere QR. I kata te hunga mātakitaki, tae noa ki taku matawai i te reira, ā, ka puta ake ngā raraunga ora ki te mata.

Ka kōrero ngā parenga ngaru o āpōpō ki tō kapua, ka matapae i te hinganga, ā, ka tono kia whakakapia i mua i tō mōhio kei te mate rātou.Kua hangaia kētia ēnei e au ki Wenzhou, ā, kei te whakamātautau-pāmata mātou i ēnei ki tētahi pokapū raraunga i Berlin.

Tērā pea kei te whakaaro koe kua pakari ngā taputapu hiko. E toru ngā panonitanga e kite ana ahau ka huri i tō rārangi hoko i roto i ngā marama 24 e whai ake nei.

Ngā MOV o te Graphene

Ka whakakapia e mātou te konutea-waikura ki te graphene. Ka taea e te MOV hou te whakahaere i te 5× te kaha ake, ā, ka noho mātao tonu. I whakahaerehia e au he patu 40 kA e rua ngā wā i runga i te taputapu kotahi. Ko te pikinga pāmahana he 42 °C anake. Ka eke te MOV paerewa ki te 120 °C, ā, ka pakaru. Ko te utu o te waeine graphene he 2.3× i tēnei rā, engari ka heke te utu mā te 18% i ia hauwhā. E matapaetia ana e au te ōritetanga i te tau 2026.

Tauira oranga e peia ana e te AI

Ka whakauruhia e au he MCU iti nei e tatau ana i ia pānga, e tuhi ana i te wā o nāianei, ā, ka whakahaere i te tātari Kalman. Ka matapae te maramara i te mutunga o te ora i roto i ngā rā ±5. Ka whiwhi koe i tētahi īmēra e kī ana, "Ka rahua te kōwae i te Paewhiri 3B i roto i ngā rā 12. Kei roto kē i tō whare putunga te wāhanga e toe ana." Kāore he tirotiro a te tangata, kāore he ohorere.

Ngā pūnaha hiko 48 V DC

He maha atu ngā tipu e neke ana ki te pahi 48 V DC mō te pūngao rā me ngā pākahiko. Ka hoahoa au i ngā parenga e piri ana ki te 65 V, ā, ka taea te whakahaere i te 100 A tonu. Ka mahi te waeine kotahi mō ngā pourewa waea me ngā rihi forklift. Kotahi te SKU e kapi ana i ngā mākete e rua, nō reira ka tapahia e koe te utu o ngā rawa ki te 30%.

Whakamutunga

Neke atu i te 480,000 ngā parepare kua tukuna e au ki ngā whenua e 34. He iti ake te utu o ia parepare i te wā e kore ai e mahi. Tukuna mai tō tuhi panui, ā, ka whakahokia mai e au he mahere whārangi kotahi hei whakaiti i tō mōrearea me tō TCO mai i te wiki e tū mai nei.
