Me pehea te whiriwhiri i te kaiwhakawhanake taputapu SPD kaiwhakanao
E 8 nga waahanga nui mo te hoko mai i Haina he taputapu tiaki ngaru
Ko taatau LSP he kaiwhakanao Haina mai i te 2010, e arotahi ana ki te whanaketanga o te ahuru ngaru me te hanga i nga taputapu paruru AC DC PV, e ngana ana ki te mahi ki o taatau kaihoko me nga hua o te kounga kairangi.
Mena he kaitautoko taputapu hiko koe, he kaihoko, he tohatoha, he kaihokohoko ranei, ka hoko koe i te AC me te DC me te SPD SP (nga taputapu paruru), me mohio koe ki nga waahanga nui e 8 mo te hoko taputapu paruru kiki (SPD) mai i Haina.
1. Te rauemi raw
(1.1) Varistor Otaa Kino - Mov
Hei waahanga matua o roto o nga SPD, kaore e kii, ko te kounga SPD e pa ana ki te kounga varistors. Kia kaha ki te whakamahi i te kounga kounga o te Mov, kia nui ake, he maha nga miihini waikura waitohu rongonui hei kowhiringa penei i a EPCOS / TDK, Littelfuse, Keko, Varsi…

Mena kei te hiahia tono koe i te SLP40-275 / 4 (UC = 275Vac, IMAX = 40kA), tirohia te teepu (ka tapa whero matou), te pou o Max. ngaohiko mahi tonu (UC) - VRMS (V), kimihia te raraunga 275V, ka kitea e maatau he tauira CJA34S-431.
PS
CJ: te tikanga o te waitohu CJ.
A: te tikanga AC
34S: te tikanga 34mm tapawha
431: te tikanga ko te ngaohiko varistor ko te 430V
I muri i te whiringa o te miihini waihora (MOV), me aro tonu tatou me pehea te whakauru atu ki roto i te whare SPD. e rua nga tikanga:
A. te miihini whakakii i te varistor, he mea whakakakahu ki te karaariki me te tae puru ranei hei whakama-makuku.
B. Ko etahi kaihanga SPD e whakamahi ana i te varistor tahanga me te hoapā, me whakamahi i te epoxy resin ki te whakauru. Me mohio ko te epoxy resin ehara i te taiao-hoa, ko nga waitohu SPD rongonui kaua e mahi pera.
C. Mo te whakaheke i te utu, ka whakamahia e etahi kaihanga SPDs te iti o te varistor hei whakakapi i te 34S varistor, me tauira, ki te hiahia koe ki te hoko i nga SPD kounga, me tumanako ko te rerenga whakaheke Tau (8 / 20μs) In = 20kA me te waatea moenga nui (8 / 20μs) Imax = 40kA, me whakamahi te 34S varistor (34 te tikanga 34mm; "S" te tikanga tapawha), engari ka whakamahia e ratau te varistor iti penei i te 20D, 25D, 32D hei whakakapi i te 34S.

(1.3) Hoahoa hanganga o roto
He maha rawa nga SPD waitohu i te maakete, ka kite koe he rua te ahua o te hoahoa hanganga o roto kei roto i te waahanga ngawari
Kāhua OBO:
ka haere mai ana te ngaru nui, ko te whanui o te hononga honohono he kuiti rawa, e kore e taea te tu atu i te 40kA ngaru.
Kāhua Dehn:
Mauruuru ki te hoahoa whaitake, ka taea e ia te tu atu i te Imax = 40kA ngaru o teianei.
(1.4) Whare kirihou
ko nga mea kounga PA66 he nylon ranei hei aukati i te ahi.
(1.5) Ko nga waahanga whakarewa, ko nga mea whakarewa nui kia mahi maitai, kaua ki te maitai.
Te whakamahi i te momo OBO i nga waahanga maitai maitai:
Dehn whakamahi i nga waahanga maitai maitai:
(1.6) Te rauemi tiaki taiao
Ko etahi wheketere e whakamahi ana i te epoxy resin ki te hiiri. He haunga te epoxy resin a kaore i te pai mo te tiaki i te taiao me te hauora.
Ka whakamahia e maatau te miihini whakakii i te varistor, kaore e hiahiatia te miihini epoxy, he pai ake mo te tiaki taiao.
2. Hanganga Whakaaturanga
Ko nga waahanga maitai e hono ana ki te Mov (varistor) me hono pono. ki te whakairinga a-ringa, ka iti noa te paera. Na ka taea e te taera aunoa te pupuri i te kounga o te kounga hua. https://www.youtube.com/watch?v=RHwNJv8hobE

8. Paera
Ahakoa nga waitohu wheketere OEM ranei, me whakarato e te kaiwhakanao he tohu tika (serigraphy), putea (kaata me te pouaka), pepa, pukapuka hiko ranei (tohutohu whakauru)
Me pehea te whiriwhiri i te kaiwhakawhanake taputapu SPD kaiwhakanao, Ko enei waahanga nui e 8 mo te hoko mai i te taputapu paruru kuru mai i Haina, ko te tumanako he pai.
He kamupene whanau matou mai i te mea kua tohaina mai nga taputapu tiaki ngaru (SPD) puta noa i te ao neke atu i te 10 tau. Kei a maatau ake rangahau me to whanaketanga, whakaputa, tautoko hangarau me te taiwhanga whakamatautau hoki.
LSP he mea hanga ehara i te mea mo nga kaainga kaainga me nga kaainga kaainga-kore anake, engari mo nga mahi umanga penei i nga raina hinu, raina hau, photovoltaics, teihana hiko me nga rerewe. Ka tiakina a maatau hua mai i nga momo hangarau, miihini, taputapu me nga taputapu puta noa i te ao.
Ka whakawhanakehia, ka hangaia hoki e maatau nga taputapu miihini kiriweti (IMD) mo nga hononga IT mana motuhake. Ka tohaina e maatau he whakautu matatini, uaua A ki te Z mo te aro turuki i te mana kiriweti i nga hohipera, umanga me nga tono motuhake.
Kaore matou e kii ka taea e matou nga mea katoa, Mena he paatai me te whakaaro mo nga mea SPD, ka koa ta matou roopu tohunga mohio ki te whakautu i o patai ka rapu i nga hua pai maau.
