E hia ngā Joule mō te Surge Protector? He Aratohu Hoko Katoa
I paraihia e au tētahi papa CNC $3,000 i te tau kua hipa nā te mea i iti te utu mō tētahi rīpene 200-Joule; kei te ara tonu ahau i te haunga.
Ka tīmata te kaha o te parenga ngaru pai i te 600 Joules mō ngā taputapu iti, ā, ka piki ake i te 2,000 Joules mō ngā tūmau, ngā mīhini CNC rānei. Tātaitia te tau ki te uara o te mea ka monohia e koe.
Kei raro nei ka whakamāramahia e au ngā tau e hiahiatia ana e koe, te hiranga o te whakatauranga, me te pehea e tohua ai e au ngā rīpene mō taku ake tipu kia taea ai e koe te tārua i te pepa, ā, kia kore ai e ngaro te papa.
He aha koe me aro nui ai ki te Whakatauranga Joule?
I tētahi wā, kāore au i aro ki ngā kupu "Joules" me te mea he mahi noa iho nā te hokohoko—tae noa ki te pikinga kotahi i whakakorea ai te wiki o te mahi whakaputa, ā, i utua ai ahau mō ngā utu mō ngā utanga rererangi.
Ki te iti rawa te whakatauranga Joule, ka mate te rīpene i muri i te kotahi pānga, ā, ka kai tonu ō mīhini i ngā titi. Kōwhiria te tau tika, ā, ka mimiti te rīpene kotahi i ngā pānga maha mō ngā tau.
I mua i taku tono i tētahi ipu rīpene, ka whakahaerehia e au he matawai tere mō te mōrearea: whakarārangihia ia taputapu kei runga i te paepae, tuhia te utu whakakapinga, kātahi ka tāpirihia he 20% o te tawhē haumaru. Mā taua ripanga māmā ahau e whakaatu mai te iti rawa o ngā Joule ka taea e au te whakaae. Mena kei raro iho i taua tau te tauira wheketere, ka whakakahoretia e au te rota—kāore he īmēra tuarua, kāore he whiriwhiringa. I ako ahau i te ara uaua ka taea e te rīpene iti iho i te $0.50 te muku i te ota $50,000.
Te Mahi a ngā Joule i te Ao Tūturu
Whakaarohia He rite ngā joule ki te tāke wahie i roto i tō waka. Ka taea e te tāke 500-Joule te mimiti i te 500 "wae" o te pūngao pītiti i mua i te paunga o ngā varistor waikura whakarewa (MOV). E whā ngā wā ka roa ake te roa o te tāke 2,000-Joule i raro i ngā pītiti kotahi. He rārangi te pāngarau, nō reira ka piri tonu taku pepa tinihanga ki taku tēpu:
| Momo Pūrere | Rahi Tūtae Noa | Ngā Joule Haumaru |
| Rīhi waea | 50 J | 300 J |
| Pūnaha Whakahaere Pūnaha Pona | 150 J | 600 J |
| Papa CNC 3-tuaka | 400 J | 1,800 J |
| PSU whatanga tūmau | 600 J | 2,500 J |
Te Utu Huna o ngā Joule "He Rawaka"
He pai ki ngā kaihoko te tango i te hēneti whakamutunga o te BOM, engari ka mate te rīpene i muri i te pānga kotahi ka akiaki koe ki te haehae me te whakakapi i te wā tiaki e whai ake nei. Ka nui ake te utu o taua wā whakatā i te tahua tiaki-ngaru katoa. Inaianei ka whakaritea e au kia rua pea ngā Joules kua tatauhia kia ora ai te rīpene tae noa ki te wā whakatā kua whakaritea e whai ake nei.
He aha ngā Joule o te Kaitiaki Ngaru?
Kei te maumahara tonu ahau ki te mata o taku kaiwhakarato i taku tono atu ki a ia kia whakakitea mai ngā tau wāhanga MOV—i mōhio ia kua mutu te kēmu.
Ko ngā joule te pūngao katoa ka taea e te kete MOV te horomi i mua i te paunga poto. Pānuihia te tapanga UL, kaua te momotuhi matotoru kei mua, nā te mea ka tāpirihia e ētahi waitohu ngā tau o ngā MOV e toru ahakoa kotahi anake te ara e hohe ana.
I roto i ia rīpene ka kitea e koe tētahi, neke atu rānei o ngā kōpae kikorangi, tata ki te hauwhā te rahi. He MOV ēnā. Ko tō rātou whānui me te matotoru te mea e whakatau ana i te whakatauranga pūngao, ehara i te whare kirihou. E hiahia ana ahau ki tētahi kōpae 14 mm mō te 1,000 Joules me te 20 mm mō te 2,000 Joules. Ki te tukuna mai e te wheketere he kōpae 10 mm, ka haere atu ahau.
Ripanga Diameter MOV vs. Pūngao
| Diameter o te Kōpae | Ngā Joule Noa | Ngā Huringa Ora i te 500 J ngā pānga |
| 10 mm | 400 J | 1 |
| 14 mm | 1,000 J | 2 |
| 20 mm | 2,000 J | 4 |
| 34 mm (2 ngā wahi) | 3,000 J | 6 |
He aha i teka ai ētahi whakatauranga
He mahi tinihanga te hono i ngā MOV e toru mai i te raina ki te koretake, mai i te raina ki te whenua, mai i te koretake ki te whenua, kātahi ka tāpirihia ō rātou whakatauranga takitahi. Ko te ara iti rawa anake ka tatauhia e te UL, nō reira ko te tau tūturu ko te hautoru o te pane matua. Ka tono tonu ahau mō te pūrongo whakamātautau UL 1449, ā, ka porowhitahia te whakatauranga kotahi-ira. Ki te whakaroa te kaihoko, ka mukua e ahau te korero.
E hia ngā joule e hiahiatia ana mō ngā horopaki rerekē?
Kei roto i taku pēke moni uruwhenua he kāri whakakikoruatia kei roto ngā taipitopito Joule mō ia hua ka hokona e au; e whakaaro ana ngā kaihoko tikanga he rerekē ahau, engari kāore taku nama e mutu.
Whakamahia te 600 J mō ngā waea me ngā rama, 1,000 J mō ngā pūreretā, 1,500 J mō ngā pouaka whakaata, me te 2,000 J, neke atu rānei, mō ngā mea katoa e nui atu ana te utu i tō utu ia marama.
He māmā noa te ture: ko te utu whakakapinga ka wehea ki te tekau ka rite ki te iti rawa o ngā Joules. E hiahia ana te mata $200 ki te 200 J iti rawa, engari ka tāpirihia e au he 50% o te wāhi mātakitaki mō te tawhito. Kāore anō taua pokatata kia rahua i ahau.
Pepa Tinihanga Horopaki
| Rūma, Mīhini rānei | Uara Pūrere Mōrahi | Ngā Joule iti rawa I Spec | Wetekina te SKU i roto i taku Whare Putunga |
| Rūma tari | Pona rorohiko $800 | 1,000 J | LKX-OP1K |
| Pouaka Whakaata rūma hui | Whakaaturanga $1,500 | 1,500 J | LKX-TV15 |
| Kāpata whakahaere CNC | $18,000 te poari | 2,500 J | LKX-CNC25 |
| Whatanga pāmu tūmau | taputapu $50,000 | 3,000 J | LKX-SF30 |
Ngā Take Tapa e Warewaretia ana e te Iwi
Ka whakahokia mai e ngā puku motuka ngā pikinga EMF e rua pea te nui ake o te ngaohiko raina. Ka rua tonu taku whakatauranga Joule ina he āputa te kawenga. Ko ngā rihi pākahiko tētahi atu mahanga—he āhua korekore, engari ka taea e te tuku aratau-whakawhiti te tuku 800 J ki roto i te raina ina tuwhera te whakawhiti. I ngaro i ahau tētahi oscilloscope $900 i taua ara; inaianei ka whiwhi ia papa whakamātautau i te iti rawa 1,500 J.
He aha te mea nui ai te whakatauranga Joule teitei mō āu taputapu hiko
I te rā i mutu ai taku raina tiki-ā-tū, tekau mā rua ngā kaiwhakahaere e tū noa ana, e $80 te utu mō ia kaiwhakahaere i te hāora—$960 i te hāora nā te mea i mutu te utu o tētahi raina 400-Joule.
He rite te mahi a ngā rīpene Joule Teitei ki tētahi hautai nui ake; ka mimiti i ngā pānga maha kia haere tonu ai te mahi a ō mīhini, ā, ka noho kore he kereme mō te whakamana.
Ka iti te kaha o ia wero. Ka mate te waeine 500-Joule i muri i te pānga o te 400-Joule kotahi, engari ka kore e aro te waeine 2,000-Joule ki ngā pānga e whā. Ko te tikanga ka whakawhitihia ngā rīpene i te PM kua whakaritea e whai ake nei, kaua i te wā o te karanga ohorere.
Ripanga Utu Katoa o te Mana Whakahaere
| Whakatauranga Rīpene | Utu @ 1 mano ngā wahi | Te Oranga i te Toa Kino | Te Utu mō te Mōrearea Wā Whakamutu | TCO 5-Tau |
| 600 J | $3.20 | 1 tau | $2,000 | $2,003 |
| 1,500 J | $4.80 | 3 tau | $500 | $505 |
| 3,000 J | $7.10 | 5 tau | $0 | $7 |
He tino kino te pāngarau: ko te penapena $1.60 i mua ka taea te utu i te rua mano i muri mai. I mutu te tautohetohe a taku CFO i taku whakaatu i tēnei pepa ki a ia.
Whakaahua o te Rahunga o te Ao Tūturu e Pupuri Ana Au
I whakapirihia e au tētahi rīpene 600-Joule kua pupuhi ki te papa pānui i te taha o te karaka wā. Kua pakaru te MOV, pērā i te pihikete, ā, kua wera te kirihou. I tōna taha he rīpene 3,000-Joule i pāngia e te uira kotahi, ā, kei te pai tonu te whakamātautau. Kāore he hiahia mō te kōrero; mā te pikitia e whakangungu.
E hia ngā Joule he Kaitiaki Ngaru Pai?
Ka kī atu ahau ki ngā kaihoko hou katoa i te rerenga kotahi: "Ka tīmata te pai i te 1,000 Joules ka piki ake kia iti ake te mamae o te utu i te wā e kore ai e whakamahia."
Ko te kaha o te parenga ngaru pai he 1,000 Joules te iti rawa, he tiwhikete UL 1449, ā, he ngaohiko kume kei raro iho i te 400 V. Mēnā he iti iho i te 400 V, he whiri hiko tērā, ehara i te parenga.
Ka whakahaerehia e au tētahi rārangi arowhai whakamutunga i mua i taku hainatanga i te PO: te nama kōnae UL, te whakatauranga Joule kotahi-ira, te iti rawa o te MOV 14 mm, me te whakamātautau ara iahiko poto 100 kA. Mēnā ka tirohia e te wheketere ngā mea e whā, ka whiwhi te rīpene i taku waitohu me te whakamana rima tau.
Rārangi Arowhai Kaihoko Tere
- [ ] Kōnae UL 1449 Putanga Tuawhā kua tāia
- [ ] Ngā joule i tāia ki te taha MOV, ehara i te pouaka anake
- [ ] Ngaohiko here ≤ 400 V
- [ ] Wā urupare
- [] Whare ātete ahi V0 whakatauranga
Ka tāpirihia e au tēnei ki te kōpaki haere, ka hoatu ki te kaimahi QC e rere ana ki Wenzhou mō ia oma tuatahi. Nā te ngaronga o tētahi taonga, ka ngaro te ipu 20-putu te roa i whakahokia mai i Hamburg—kāore anō kia pērā anō.
Whakamutunga
Kōwhiria te whakatauranga Joule teitei rawa atu e taea ana e tō tahua, whakamātauria ngā MOV e koe, ka moe pērā i ahau—me te mōhio ka ngunguru tonu te aho i muri i te awha e whai ake nei.
