SPD ya Power Supply System Series Selection Guide
Kuyika kwa SPD pamalo aliwonse otetezedwa ndi mphezi, kutengera mawonekedwe amagetsi otsika, kuyika zida zamagetsi molingana ndi gulu lamagetsi opitilira voteji, kutchinjiriza kwake kupirira mphamvu yamagetsi kumatha kudziwa kusankha kwa SPD.Malinga ndi muyezo wa mawonekedwe amagetsi otsika, pangani zida zamagetsi molingana ndi gulu lamagetsi opitilira muyeso monga mulingo wamasigino, mulingo wotsitsa, mulingo wogawa ndi wowongolera, mulingo wamagetsi.Insulation yake yolimbana ndi mphamvu yamagetsi ndi: 1500V, 2500V, 4000V, 6000V.Monga pa malo otetezedwa zida unsembe malo osiyana ndi osiyana mphezi panopa osiyana mphezi zone chitetezo, kudziwa malo unsembe wa SPD kwa magetsi ndi mphamvu yopuma.
Mtunda woyika pakati pa gawo lililonse la SPD suyenera kupitirira 10m, mtunda pakati pa SPD ndi zida zotetezedwa uyenera kukhala waufupi momwe ungathere, osapitilira 10m.Ngati chifukwa cha kuchepa kwa malo oyika, sikungatsimikizire kutalika kwa mtunda, ndiye kuti muyenera kuyika gawo lolumikizirana pakati pa gawo lililonse la SPD, pangitsa kuti SPD ya pambuyo pake itetezedwe ndi gulu lakale la SPD.Mumagetsi otsika mphamvu zamagetsi, kulumikiza inductor kumatha kukwaniritsa cholinga cholumikizira.
SPD ya mfundo yosankha zopangira magetsi
Max.voteji yopitilira ntchito: yayikulu kuposa zida zotetezedwa, max system.voteji yogwira ntchito mosalekeza.
TT System: Uc≥1.55Uo (Uo ndi otsika voteji dongosolo kuti null line voteji)
TN System: Uc≥1.15Uo
IT System: Uc≥1.15Uo (Uo ndi dongosolo lotsika lamagetsi ku mzere voteji)
Mulingo wa Chitetezo cha Voltage: wocheperako kuposa kutsekereza kupirira mphamvu yamagetsi yazida zotetezedwa
Kutulutsa koyezera pakali pano: kutsimikiziridwa malinga ndi momwe mphezi zilili pamalo omwe adayikidwa komanso chitetezo cha mphezi.
