ʻO ka ʻenehana palekana surge (a i ʻole pōkole iā SPD) ʻaʻole ia he huahana e ʻike ʻia e ka lehulehu. ʻIke ka lehulehu e pilikia ka maikaʻi o ka mana i loko o ko mākou kaiāulu i mea e hoʻohana nui ʻia ai nā polokalamu uila loea a mea hoʻohana ʻia paha. ʻIke lākou e pili ana i ka UPS hiki ke hāʻawi i ka hoʻouka uila uninterrupted. ʻIke lākou i ka stabilizer kūlā ʻohana, e like me kona inoa i kuhikuhi ʻia, hoʻokū a hoʻoponopono ʻole i ka uila. Akā ʻo ka hapanui o ka poʻe e leʻaleʻa ana i ka palekana e lawe mai i ka mea palekana e hūnā i ka ʻike.

Introduction

Kuhi kēia ʻatikala ʻaʻohe ʻike o ka mea heluhelu i ka pale o ka piʻi. Hoʻomaʻalahi ʻia kekahi o nā ʻike no ka pono o ka ʻike maʻalahi. Ua hoʻāʻo mākou e hoʻolilo i ka ʻike loea i kā mākou ʻōlelo i kēlā me kēia lā akā i ka manawa like, ʻaʻole hiki ke alo ʻia e lilo ana kahi pololei iā mākou.

A i loko o kēia hōʻike, lawe mākou i kekahi mea hoʻomalu palekana i hoʻopuka ʻia e nā hui uila a me nā uila i loaʻa iā mākou mai nā kumu lehulehu. Ma kēia mea mahalo mākou iā lākou no kā lākou hana i ke aʻo ʻana i ka lehulehu. Inā he paio kekahi mea, e ʻoluʻolu kāhea iā mā ou.

ʻO kekahi mea nui i ka pale uila a me ka pale ʻana i ka luahi ʻaʻole ia he ʻepekema kikoʻī. ʻO kahi laʻana, ʻike mākou makemake ka uila i ka pā i nā mea kiʻekiʻe a kolohe. No laila mākou e hoʻohana ai i ka lāʻau uila e ʻumeʻume i ka uila a hoʻohuli i kona au i ka honua. Eia naʻe kahi hana i hoʻokumu ʻia ma ka likelika, ʻaʻole he lula. I nā manawa he nui, ua pā ka uila i nā mea ʻē aʻe ʻoiai aia kahi lāʻau uila lōʻihi a kūwā kokoke. ʻO kahi laʻana, ʻo ESE (Early Streamer Emission) i manaʻo ʻia he ʻano hou o ke koʻokoʻo uila a no laila pono e ʻoi aku ka maikaʻi o ka hana. Eia naʻe, he huahana hoʻopaʻapaʻa loa ia a ka poʻe loea he nui i manaʻoʻiʻo a ʻae ʻaʻohe ona maikaʻi ma mua o ka lāʻau uila māmā. E like me ka pale piʻi, ʻoi aku ka nui o ka paio. ʻO ke kūlana IEC, ka mea i noi nui ʻia a hoʻolālā ʻia e nā poʻe loea ʻEulopa, wehewehe i ka nalu o ka uila pololei e like me 10/350 μs impulse a UL standard, i manaʻo nui ʻia a i hoʻolālā ʻia e nā poʻe loea ʻAmelika, ʻaʻole ʻike i kēlā ʻano nalu

Mai kā mākou kuanaʻike, e lilo ana ko mākou ʻike i ka uila i mea kikoʻī a pololei a kūpono hoʻi i ka wā e hana hou ana mākou i ka noiʻi. ʻO kahi laʻana, hoʻomohala ʻia nā huahana pale pale ākea āpau i kēia mau lā ma muli o ke kumumanaʻo ʻo ke au uila kahi hoʻokahi nalu impulse. Eia nō naʻe kekahi mau SPD i hiki ke hala i nā hoʻokolohua a pau i loko o ka hale hana ke hāʻule mau nei ma ke kahua ke kani maoli ka uila. Pēlā nā makahiki i hala iho nei, ua nui a ʻoi aku ka nui o ka poʻe loea i manaʻoʻiʻo i ke au uila he ʻano nalu he nui. ʻO kēia ka holomua a ʻoiaʻiʻo e hoʻomaikaʻi i ka hana o nā pale pale ākea e hoʻomohala ma muli o kēlā.

Eia nō naʻe i kēia ʻatikala, e ʻeli mākou i nā kumuhana hoʻopaʻapaʻa. Hoʻomaʻo mākou e hāʻawi i kahi kula haʻahaʻa akā piha, piha i ka hoʻolauna pale a me ka pale pale. No laila, e hoʻomaka kākou.

1. Mālama uila Kuleana VS Surge

E nīnau paha ʻoe no ke aha e pono ai mākou e ʻike i kekahi mea e pili ana i ka pale uila inā kamaʻilio mākou e pili ana i ka pale o ka hōʻemi. ʻAe, pili kēia mau manaʻo ʻelua i ka nui o nā loea i kumu maoli ʻia e ka uila. Manaʻo mākou e pili ana i ke kumu o nā kauā ma ka mokuna aʻe. Manaʻo kekahi mau ʻōmaʻomaʻi ʻo ka pale o ka mālama ʻana he hapa o ka mālama uila. Ke manaʻo nei kēia mau ʻāno i hiki ke hoʻokaʻawale nā ​​mea uila i nā ʻāpana ʻelua: ʻo ka mālama o ka uila waho ka waiwai o ka uila. hoʻolako a i ʻole ka palena laina / hōʻailona.

ʻO ka pale uila he ʻōnaehana paʻakikī e pili ana i nā huahana like ʻole. ʻO ka pale ʻana he ʻāpana wale nō kahi o ka ʻōnaehana pale uila i hoʻonohonoho ʻia. No nā mea maʻamau, ʻaʻole pono e eli i ka kūkākūkā hoʻokūkū. Ma hope o nā mea a pau, e like me kā mākou i ʻōlelo ai, ʻaʻole ia he ʻepekema ākea maoli. No mākou, ʻaʻole paha ia he 100% maopopo maʻalahi e hoʻomaopopo i ka pale uila a me kona pilina me ka hāmeʻa pale palekana.

Mālama Māmā

2. Ke Hoihoi

ʻĀ, e kamaʻilio hou aʻe ana mākou e pili ana i nā piʻina i kēia kau. ʻOiai ua hoʻohana mākou i ka manawa i kēia manawa pinepine i ka manawa i hala, akā ʻaʻole mākou i hāʻawi i kahi wehewehe kūpono i kēia manawa. A nui a hewahewa e pili ana i kēia huaʻōlelo.

ʻAʻole wale ka lawe ʻana i ka lūlū i ka waiwai, akā ua lawe pū mai nō hoʻi ia i ka pilikia pilikino.

3. Hāʻawi i ka ʻeha Pūnaewele / Surge Pihi Pūnaewele

Me ka ʻike kumu o ka palekana o ka uila / hōʻemi a hoʻemi nui a hoʻolauna i hōʻike ʻia i ka hālāwai ma mua, e aʻo ana mākou e aʻo hou e pili ana i ka ʻōnaehana pale ʻoiʻi. Eia kekahi mea, e kapa ʻia ʻo ia o Surge Protective Device e hoʻokumu i nā palapala ʻona a me nā kūlana āpau. Akā he nui ka poʻe, ʻo ka ʻoihana i ke kahua pale o ka mālama ʻana e like me ka hoʻohana ʻana i ka ʻōnaehana pale ʻoiʻi. Malama no ka mea ke kani e like me ka ʻōlelo maʻamau i kēlā me kēia lā.

Hiki iā ʻoe ke ʻike i nā ʻano ʻelua o ka pale o ka pale ma ka mākeke e like me ka hōʻike o nā kiʻi ma lalo. Hoʻomaopopo pono ʻole nā ​​kiʻi i ke aʻa acutal o ia huahana. Panel type SPD ka nui o ka nui ma ka nui ma mua o ka DIN-rain SPD.

No laila he aha pololei ia kahi pale pale piʻi? E like me ka manaʻo o kona inoa, he mea pono ia e pale aku i nā piʻina. Akā, pehea? Hiki iā ia ke hoʻopau i ka nalu? E nānā i ka hana o kahi mea pale pale (SPD). Hiki iā mākou ke ʻōlelo ua hoʻohana ʻia kahi SPD e hoʻohuli i ka nui o ka uila a i kēia manawa me ka maluhia i ka honua ma mua o ka hiki ʻana i nā pono pale. Hiki iā mākou ke hoʻohana i nā lakohana pale pale i ka lab e ʻike ai i kāna hana.

Pehea e hana ai ʻo SPD?

Hoʻopili ka SPD. ʻO ke kūleʻa ʻana me ka hoʻohaʻahaʻa nui ʻana i ka piʻi ʻana aʻe. Hiki iā ʻoe ke noʻonoʻo iā SPD he puka a wīlī e like me ke kahe. Ma lalo o ke ʻano maʻamau, pani ʻia ka ʻīpuka akā ke ʻike nei ka neʻe o ka neʻe, e wehe koke ka puka a hiki ke hoʻoneʻe ʻia ka piʻi ʻana. E hoʻonohonoho maʻalahi i ke kūlana kiʻekiʻe ma hope o ka hoʻokō ʻana.

Lawe ʻo SPD i ka hōʻeha mai i ola nā mea i pale ʻia. Overtime, SPD e hiki mai i ka hopena o ke ola ma muli o nā hana he nui e hoʻomau ana. Mālama iā ia iho a hiki ke ola nā mea e pale ʻia.

ʻO ka hopena hope loa no kahi SPD ke kaumaha.

Hoʻonohonoho ʻana i nā ʻāpana uila

I kēia kau, e kamaʻilio mākou e pili ana i nā ʻāpana SPD. ʻO ke kumu, aia 4 mau mea nui SPD: hakahaka kahawai, Mov, GDT a me TVS. He ʻano ʻokoʻa ko kēia mau ʻāpana akā lawelawe lākou āpau i kahi hana like: maopopo i ke kūlana maʻamau, nui loa ke kūʻē ʻana i hiki ʻole i kahi au ke ukali ma lalo o ke kūlana piʻi e hāʻule koke ke kūʻē ʻana a kokoke i ka zero i hiki ai i ka nalu ke hele i ka honua ma kahi o e kahe ana i nā mea hana o lalo i pale ʻia. ʻO ia ke kumu a mākou i kapa aku ai i kēia mau ʻāpana 4 ʻaʻole nā ​​laina laina. Eia nō naʻe he ʻokoʻa ko lākou a hiki iā mākou ke kākau i kahi ʻatikala ʻē aʻe e kamaʻilio e pili ana i kā lākou ʻokoʻa. Akā i kēia manawa, nā mea a pau e pono ai mākou e ʻike, lawelawe lākou āpau i ka hana like: e hoʻohuli i ka ʻeʻewa i ka honua.

E nānā i kēia mau mea pale pale.

ʻO Prosurge's SMTMOV a me PTMOV ʻelua mau mana hou o ka Mov kuʻuna. Palekana lākou i nā palekana a palekana iā lākou iho i lawe ʻia e nā hana nui SPD e kūkulu i kā lākou huahana pale pale.

Hana i nā ʻenehana pale hoʻomalu

Ma ka laulā nui, he ʻelua mau ʻānina nui: IEC maʻamau a me ke ʻano UL. ʻO ka UL maʻamau e hoʻohana nui ʻia ma ʻAmelika ʻAmelika a me kekahi mau ʻāpana ma ʻAmelika Hema a me Philippines. ʻOi aku ka pili o IEC standard i kahi ākea a puni ka honua. ʻO ka moʻoʻōlelo China GB o 18802 ka mea i hōʻole ʻia mai ka maʻamau ʻo IEC 61643-11.

No ke aha e hiki ʻole ai iā mākou ke loaʻa i kahi pae honua a puni ka honua? ʻĀ, ʻo kekahi o nā wehewehe ʻana he mau manaʻo like ʻole ko ka poʻe loea ʻEulopa a me ka poʻe loea o ʻAmelika i ka hoʻomaopopo ʻana i ka uila a me ka ʻū.

He kumuhana ka holomua ʻana. No ka laʻana, ma mua aku ʻaʻohe mea maʻamau o ka IEC maʻamau i SPD i hoʻohana ʻia ma ka noi DC / PV. ʻO ka IEC 61643-11 ke lanakila nei no ka hoʻoulu ʻana o ka mana AC. Akā i kēia manawa ua loaʻa iā mākou ka mana no ka IEC 61643-31 maʻamau no SPD i hoʻohana ʻia ma ka palapala DC / PV.

Hoʻokomo pū ʻia kahi loiloi palekana

ʻ,, Eia paha kēia he papa maʻalahi loa e kākau no ka mea ke manaʻo nei mākou hiki iā ʻoe ke hele i Youtube no ka nui o nā wikiō e pili ana i ka hoʻokomo ʻana o SPD, a i ʻole he DIN-rail SPD a i ʻole panel panel. ʻOiaʻiʻo, hiki iā ʻoe ke nānā i kā mākou kiʻi kiʻi e aʻo hou aʻe e pili ana. Kuhi ʻia ʻia ʻo ka hoʻokomo ʻana o kahi mea palekana i mea e pale ʻia e nā mea uila loea ʻole.

Eia kekahi kiʻi kiʻi o ka mīkini pale palekana 1 / 2 / 3 ma ke kiko UL.

E like me nā mea ʻē aʻe, e wehewehe paha mākou iā lākou ma hope i kekahi mau mea i makemake ʻia e lōʻihi loa ia. I kēia manawa, ʻo nā mea āpau e pono ai ke ʻike, ua helu ʻia nā SPD ma nā ʻano ʻelua ma nā ʻUka a UL a me nā IEC.

Me nā kīʻaha koʻikoʻi o nā Hāmeʻa pale Surge

Inā ʻoe e nānā i kahi hāmeʻa pale pale, ʻike ʻoe i kekahi mau palena ma kāna māka ʻana, no ka laʻana, MCOV, In, Imax, VPR, SCCR. He aha nā manaʻo a no ke aha he mea nui? ʻĀ, i kēia kau, e kamaʻilio ana mākou e pili ana i ia.

Hōʻailona kūhelu (Un)

ʻO ka inoa nominal 'inoa'. No laila ʻo kahi uila uila ka uila i kapa ʻia ka inoa. ʻO kahi laʻana, ʻo ka volta nominal o ka ʻōnaehana hoʻolako i nā ʻāina he 220. Akā ua ʻae ʻia kona waiwai maoli e hoʻololi i waena o kahi pae ākea.

Ke Kuhi Hoʻolaha Kūlohelohe Kūʻai (MCOV / Uc) 

ʻO ka helu kiʻekiʻe loa e hoʻokuʻi ʻia ka mīkini e hele mau. ʻO ka MCOV maʻamau ka 1.1-1.2 manawa kiʻekiʻe ma mua o Un. Akā ma ka wahi me ka maka palena mana ʻole, e hele nui a ʻike ka pila, no laila e koho pono i kahi MCOV SPD kiʻekiʻe. No 220V Un, hiki i nā ʻāina ʻEulopa ke koho 250V MCOV SPD akā i kekahi o nā mākeke e like me India, manaʻo mākou iā MCOV 320V a i ʻole 385V. E hōʻike aku: Aia ka voltage ma luna o MCOV i kapa ʻia Temporary Overvoltage (TOV). ʻOi aku ma mua o 90% o ka wela o ka SPD ma muli o TOV.

Ka Hōʻuluʻulu Manaʻo Voltage (VPR) / Hōʻike iā-Voltage

ʻO ia ka nui o ka uila a ka SPD e ʻae ai e hele i ka hāmeʻa pale a ʻo ia ka haʻahaʻa ʻoi aku ka maikaʻi. ʻO kahi laʻana, hiki i ka hāmeʻa pale ke pale aku i ka 800V kiʻekiʻe loa. Inā 1000V ka SPD's VRP, e hōʻino ʻia a hōʻino ʻia ka hāmeʻa pale ʻia.

E hali i ka mana o kēia manawa

ʻO ia ka nui o ke kahe o kēia manawa a SPD hiki ke hoʻi i ka honua i ka wā o ka hanana a he hōʻailona ia o ke ola o kahi SPD. ʻO kahi laʻana, ʻoi aku ka lōʻihi o ke ola o 200kA SPD ma mua o 100kA SPD ma lalo o ke kūlana like.

Hoʻolaha inoa inoa

ʻO ia ka hopena o ka piʻiʻana o ka luʻi i kēia manawa ma o ka SPD. Pono ka SPD e noho hana ma hope o 15 i nā surges. ʻO kahi ke kuhikuhi o ka hiki o ka SPD a ʻo ke ana o ka hoʻokō ʻana o ka SPD i ka wā e hoʻokomo ʻia a kau ʻia i nā hanana hoʻokūkū pili kokoke i ke kūlana ola maoli ʻoi aku ka kiʻekiʻe.

Hoʻolaha nui loa (Imax)

ʻO ia ka hopena o ka piʻiʻana o ka luʻi i kēia manawa ma o ka SPD. Pono ka noho o SPD ma hope o ka 1 Imax kahakiʻi. ʻO ka maʻamau, ʻo ia ka 2-2.5 ka manawa o ka waiwai o In. ʻO ia hoʻi kahi hōʻailona o ka palaualelo o kahi SPD. Akā ʻoi aku kahi pōkole ʻoi aku ka mea nui ma mua o ka mea ʻo ka Imax kahi hōʻike koʻikoʻi a me ke kūlana maoli, loaʻa ʻole ka ikaika o ka pena ikaika. No kēia hiʻohiʻona, ʻoi aku ka kiʻekiʻe.

Ka Lālā Loa o ka Lā Leka Pākawā (SCCR)

ʻO ia ka pae kiʻekiʻe o ka pōkole pōkole o kēia ka mea hiki ke hoʻokūkū a hoʻonoho paha a ʻoi aku ka ʻoi aku ka kiʻekiʻe. Ua hala nā hōʻike nui o Prosurge ma 200kA SCCR hōʻike pālua ma kahi ʻUkau UL ʻole ʻole o ka mea hoʻokūkū kūwaho o waho a me ka hoʻopiha ʻo ia ka hana maikaʻi loa i ka ʻoihana.

Hoʻohana i nā Pūnaewele Pūnaewele Hona

Hoʻohana nui ʻia nā mea pale kaua i nā ʻenehana like ʻole, ʻo ia hoʻi no kēlā me kēia ʻoihana. Aia ma lalo iho nei kahi papa inoa o nā noi pale palekana a me nā hāmeʻa e hoʻomākaukau ai e Prosurge. Ma kēlā me kēia noi, hōʻike mākou i ka pono SPD a me nā wahi hoʻonohonoho. Inā makemake ʻoe i kekahi o nā noi, hiki iā ʻoe ke kaomi a aʻoi hou aku.

hōʻuluʻulu manaʻo

Ma ka hope loa, hele mākou i ka hopena o kēia ʻatikala. Ma kēiaʻatikala, e kamaʻilio mākou e pili ana i kekahi mau mea hoihoi e like me ka pale uila, ka mālama i ka hōʻeha, nā hōʻemi a me nā pale pale pale. Ke manaʻo nei wau ua maopopo ʻoe i ke kumu o ka pale palekana pale. Akā inā makemake ʻoe e aʻo hou e pili ana i kēia kumuhana, loaʻa a mākou i nā ʻatikala e pili ana i ka mahele hoʻonaʻauao koʻikoʻi ma kā mākou pūnaewele.

A ʻo ka mea hope loa o kēia ʻatikala ke hāʻawi aku i kā mākou mahalo i kēlā mau hui e hana ana i nā wikiō he nui, nā kiʻi, nā ʻatikala a me nā ʻano like ʻole o ke kumuhana o ka pale palekana. ʻO lākou ka mea mua ma kā mākou ʻoihana. E ala ʻia e lākou, ke hāʻawi nei mākou i kā mākou kuleana.

Inā makemake ʻoe i kēia ʻatikala, hiki iā ʻoe ke kōkua e kaʻana ia ia!
