Ka kino rānei ngā parenga ngaru?
I ngaro i ahau tētahi pūmana CNC $3,000 i mua nā te mea i mutu puku te whiri "hou". Nā taua wero i ako ahau ki te whakahē i ia rama LED e mura ana.
Āe, ngā parenga ngaru ka pakaru. Ka pakaru ā rātou MOV, ka iti ake te kaha e mimitia ana, ā, ka mutu ka tukua te wero e whai ake nei ki roto i ō taputapu.Ka ine au i tēnei pirau i roto i taku taiwhanga Wenzhou i ia wiki.
Pānuihia tonutia, ā, māku e whakaatu atu ki a koe ngā tohu, ngā tau, me ngā ture whakakapinga e whakamahia ana e mātou ina tukuna ana e mātou ngā ipu 40-putu te roa ki Berlin me Birmingham.
Me pēhea Ngā Tiaki Pupuhi Mahi?
Kei te maumahara tonu ahau ki taku kitenga tuatahi i tētahi MOV pupuhi pērā i te pahū iti i roto i tētahi pouaka kirihou mā. Nā taua whakaahua ahau i whakatenatena he toa ēnei wāhanga he poto te roa o te ora.
He parenga ngaru ka ringihia ngā volts tāpiri ki roto i ngā varistors waikura-konganuku. Ka mimitihia e ngā varistor te pānga, engari ka kainga e ia pānga kia pakaru rā anō, kia mutu rā anō te kawe hiko.Ka whakamātauria e au tēnei i roto i tā mātou wheketere 2,000 m² te rahi.
He aha kei roto i te Rīpene?
Ko te nuinga o ngā kaihoko ka kite noa i te pana kanapa me te rama matomato. Ka whakatuwherahia e au te pouaka ka whakakitea ki a rātou ngā wāhanga e toru:
| Wāhanga | Hopa | Ngāwari |
| MOV | Ngā rawhi hiko teitei | Ngā pakaru i muri i te ~300 J |
| Ngongo hau | Ka whakahaere i ngā raina waea | Ka puhoi ake te mau i te MOV |
| Pūhiko | Ka tapahia rawatia | Whakamahinga kotahi |
E hia ngā joule ka taea e koe te whakapau?
He rite ngā joule ki te moni i roto i te pēke moni. Ka taea e te waeine 1,000 J te tu atu i te kotahi pānga 1,000 J, tekau rānei pānga 100 J. I tuhia e au ngā ngaru i roto i te tipu o Hamburg mō ngā marama e ono. E whakaatu ana te ripanga i raro nei i ngā mea i pā ki ā rātou raina:
| Marama | Pūngao Pupuhi(J) | Te maha o ngā Painga |
| Hanuere | 120 | 14 |
| Pēpuere | 85 | 9 |
| Maehe | 350 | 3 |
| Tapeke | 555 | 26 |
I te taenga ki Poutū-te-rangi, e 445 J anake te toenga o te hinu i toe i te kaitiaki. Mēnā ka pēhia pērā, kua kore rawa i mua i te raumati.
He aha te teka o te rama matomato
Ko te rama LED anake hei whakaatu kei te ora te fuse. Ka taea te wehe i te MOV kia rua, ā, ka tiaho tonu te rama. Ka tono atu ahau ki ngā kaihoko kia whakamātauria mā te whakamahi i tētahi taputapu whakamātautau putanga māmā me tētahi pēke uta kotahi i te tau. Ki te piki ake te hekenga o te ngaohiko i runga ake i te 5%, kua ngaro te MOV.
Ngā Tohu e Pakaru Ana Tō Kaitiaki Ngaru
I te tau kua hipa, i tukuna mai e tētahi kiritaki Wīwī tētahi puranga he tino ataahua te āhua o waho. I roto, he rite ngā ara parauri kua wera ki ngā rori ririki. Ko te haunga o te kirihou kua tunua he whakatūpato kāore au e wareware.
Ka pakaru tō parenga ngaru mena ka mahana te pouaka, ka kimo te rama LED, ka rangona rānei he haruru iti. Ka whakawhitihia e au tetahi rīpene e whakaatu ana i ēnei tohu.Ka tirohia e au 100% o ā mātou kātene e tukuna atu ana mō ēnei tohu.
Te Pā o te Anga
I muri i te haora kotahi o te uta, me noho tonu te pāmahana o te mata i raro i te 40 °C. Ka whakamahia e au he pū IR $20, ka matawai i ia putanga. Ko te tikanga o te wāhi wera ko te turuturu o te iahiko o te MOV, ā, ka hurihia te pūngao hei wera.
Whakamātautau hongi
He kakara kirihou, he kakara whakarewa te papa hauora. Ka puta he kakara reka, he kakara koi i te MOV e memeha haere ana. Ka whakangungu ahau i tā mātou tīma QC kia kite i tēnei i raro iho i te rima hēkona i runga i te raina.
Pepa Tinihanga LED
I hanga e mātou he tēpu iti ka tāpirihia e mātou ki roto i ia kātene kaweake:
| Āhua LED | Te tikanga | Mahi |
| Kakariki pumau | He pai katoa | Me whakamahi tonu |
| Whakaweto | Kua pakaru te fiusi | Whakakapia inaianei |
| Pōuriuri, kanapa rānei | MOV e mate ana | Whakakapia wawe |
Kia pēhea te roa o te ora o ngā parenga ngaru?
Kei te pupuri ahau i tētahi whata tauira e rere ana i ngā rā katoa, i ngā rā e whitu, i te 1.5× te ngaohiko whakatauranga. I muri i ngā marama 36, kua heke te haurua o ngā MOV ki raro iho i te 70% te ngaohiko rawhi. E whakaatu ana tēnā kei te haere tonu te karaka.
E toru ki te rima tau te roa o te oranga o te nuinga o ngā parenga ngaru i roto i tētahi tari ma. I roto i tētahi toa hokohoko wera me ngā pikinga ngaru i ia rā, me tatari kia kotahi ki te rua tau.Ka tāia e au te rā whakaputa ki ia waeine ka hokona e mātou.
Ngā Mea e Kiia Ana e ngā Paerewa
E ai ki te IEC 61643-11 me mahi tonu te MOV i muri i te 1,000 ngaru kotahi-amp. He nui te ahua o tēnā, engari ka taea e te tupuhi raumati kotahi te tuku i te 20 ngau. Whakamahia te pāngarau, ā, ka kite koe he aha ahau i akiaki ai i ngā kaihoko ki te whakakapi i ngā rīpene i runga i te maramataka, kaua i runga i te tumanako.
Ripanga Raraunga Tuturu mai i tā Mātou Taiwhanga
I whakahaerehia e mātou he 200 tauira i te 40 °C me te 230 V. E whakaatu ana te ripanga i te pikinga o te ngaohiko o te rawhi mā te 10%:
| Whakatauranga Joule | Te Ora Waenga (ngā marama) | 5% I rahua i (ngā marama) |
| 600 J | 28 | 18 |
| 900 J | 42 | 30 |
| 1,500 J | 60 | 48 |
Ko te rua o ngā joule ka tata rua te roa o te ora. Koia ahau i hoko atu ai i ngā papa he nui ake te joule ki ngā wheketere Tiamana ahakoa he 18% te utu nui ake.
Kei te tiakina tonutia koe?
I tukuna e au he mēra mō ngā pātene whakamātautau e 500 ki ngā kiritaki i te hauwhā whakamutunga. E 23% noa iho i pēhi i aua pātene. Ko ētahi atu kei te rere matapo, kei te petipeti i runga i tētahi ara petipeti kua mate kē pea.
Pēhia te pātene whakamātautau kia rua ngā wā i te tau. Ki te noho pōuri tonu te rama LED matomato i muri i te whakamātautau, kua pau ngā MOV, ā, kāore koe e tiakina ana.Ka tāpirihia e au tēnei kāri ki ia kātene.
Aratohu Tirotiro Whaiaro Tere
- Momotuhia ngā uta katoa.
- Pēhia me te pupuri i te pātene whakamātautau mō te 3 hēkona.
- Tukua, ka mātaki i te LED.
- Ki te hoki mārama mai, kei a koe tonu te ora.
- Ki te noho pōuri, ki te memeha rānei, whakamahia anō te rīpene.
Taku Otinga $0.25
Ka tāia e mātou he waehere QR ki ia pouaka. Matawaihia, ā, ka kite koe i te tatau joule tika e toe ana, i runga i te waehere rā me te raupaparorohiko māmā. Ehara i te mea mai i te taiwhanga, engari he pai ake te matapae.
Āhea koe me whakakapi i tētahi parenga ngaru?
Ka whakakapia e au ngā rīpene katoa o taku ake tari i te rā mahi tuatahi i muri i te Tau Hou Hainamana. E rite ana ki te whakawhiti pākahiko o te pūoko paoa ki ahau—he inihua iti te utu mō te mate nui.
Whakakapia te parenga ngaru i muri i tētahi pānga uira nui, i ia toru tau, i te wā rānei e mahana ai te pouaka, e rerekē ai rānei te mahi a te LED.Ka tukuna e au ngā taonga hou ki Milan i ia hauwhā kia taea ai e ngā kaihoko te whai i tēnei ture.
Te utu mō te tatari
E rima tau te roa o te tatari a tētahi kiritaki o te UK. Nā te pikinga o te utu, e toru ngā PLC i mate, ā, e £4,800 te utu mō ia rīpene. £12 te utu mō ngā rīpene hou. He mamae te pāngarau.
Maramataka Whakakapinga Māmā
Ka whakapirihia e mātou tēnei ki roto i te taupoki o te kātene:
| Tau i roto i te Whakamahinga | Mahi |
| 0–1 | Whakamātautau anake |
| 2 | Whakamātauria kia rua ngā wā |
| 3 | Ngā whakakapinga ota |
| 4+ | Whakakapia inaianei, kāore he whakamātautau e hiahiatia ana |
Whakapiria tēnei ki tō tatau panera, ā, e kore koe e whakapae anō.
Whakamutunga
Kua ngaro taku moni, nō reira kāore koe e hiahia ki te mahi pera. Whakamātauria kia rua ngā wā, whakawhitihia ia toru tau, ā, hoko joule pērā i te hoko kawhe—he pai ake te nui. Tukuna mai he karere ki caroline@leikexing.com, ā, ka tukuna atu e au ngā papa hou mai i Wenzhou i mua i te pānga mai o te awha e whai ake nei.
