Ka Papa Hana Manaʻo Kūwaena (SPD)

ʻO ka maʻamau, nānā nui ka poʻe i ka hana o kahi mea pale pale (SPD) e like me ka hiki ke piʻi. He mea nui ka hiki ke piʻi. Nui a hewahewa nā pale pale (SPDs) ma ka mākeke hiki ʻole ke hoʻokō i ka hiki ke piʻi aʻe i kūkala. Eia kahi kiʻi a me ke wikiō o kahi SPD i pohā i ka hoʻāʻo o kēia manawa (Imax 40kA):

Ka palekana no ka Pūnaewele Māiʻi (SPD)

Eia naʻe ua nānā iki ʻia i ka palekana o kahi mea pale pale. Eia nō naʻe, hiki i ka SPD hoʻolālā maikaʻi ʻole ke weliweli a ʻo ia kekahi o nā kumu nui no ka weliweli ahi. Ma lalo iho nei kekahi mau kiʻi SPD i kuni ʻia:

ʻO SPD / MOV ka mea i make i ka wā kahiko (TOV)

ʻAʻole hiki i ka SPDs ke hoʻohana pono a hoʻohana hewaʻole paha i nā MOV i hiki ke hele i loko o ka hoʻomehana wela, hiki i ke alakaʻi kaʻapuni, ka hoʻouluʻana, ka uahi a me ka pilikia ahi no ka:

• Ka hopena o ke ola
• Kākoʻo nuiʻia nā kūlana kiʻekiʻe / Temiʻo no ka nohoʻana (TOV)
• Hoʻopihaʻia me ka manahu i manaʻoʻoleʻia

ʻO MOV a SPD paha nā mea pale o ka Transient Overvoltage (aiʻole ka lōʻihi) akā nā mea i pōpilikia o ka Overvoltage Temporary.

Pāʻoihana palekana palekana ʻōpikipiki - ʻenehana TPAE

Ua hoʻomohala ʻo Prosurge i ka ʻenehana TPAE (Thermally Protected Arc Extinguishing) e hoʻonā i ka pilikia palekana o SPD a loaʻa iā mākou kēia ʻenehana i pateni ʻia ma USA, Kelemania, Korea a me Kina.

Ma muli o ka ʻenehana TPAE, ua hoʻomohala mākou i kā mākou kī nui SPD - SMTMOV a me PTMOV.

Hiki iā ʻoe ke ʻike pehea e palekana ai kā mākou huahana i kahi situtation overvoltage i kākoʻo ʻia i ka wā i puhi ʻia ka huahana a kā mākou mea hoʻokūkū.

I lalo o ka hoʻāʻo, ua hoʻāʻo ʻia nā SPD ʻelua ma lalo o TOV (overvoltage transient). E ʻike pehea ka ʻokoʻa o ka hopena no SPD me ka pale TPAE a me SPD me ka ʻole o ka pale TPAE:

ʻO ka palekana kiʻekiʻe ma ka mālamaʻana
