Kodi ma SPD angateteze ku mitundu yonse ya kusokonezeka kwa magetsi?
Ma SPD apangidwa kuti ateteze ku kukwera kwadzidzidzi kwa nthawi zambiri, koma ali ndi malire kutengera kuwerengera kwawo. Sangateteze mokwanira ku kukwera kwamphamvu kwambiri kapena kugunda kwa mphezi mwachindunji ngati chipangizocho sichinayesedwe bwino. Kuti muteteze mokwanira, mitundu yosiyanasiyana ya SPD ingagwiritsidwe ntchito.
Kusiyana pakati pa Mtundu 1, Mtundu 2 Chitetezo cha Chipangizo SPD
Mtundu 1 SPD Yapangidwa kuti igwire ntchito yolimbana ndi kukwera kwa magetsi kwamphamvu kwambiri, komwe nthawi zambiri kumachitika chifukwa cha kugunda kwa mphezi mwachindunji. Zipangizozi nthawi zambiri zimayikidwa pakhomo lalikulu la magetsi la nyumba, zomwe zimateteza kwambiri ku zinthu zoopsa ngati zimenezi. Ma SPD amtundu wa 1 amatha kuyendetsa mafunde amagetsi mpaka 100 kA kapena kuposerapo, pogwiritsa ntchito zida zoteteza mphamvu zambiri monga zoletsa mpweya kuti zitsimikizire kuti dongosololi latetezedwa panthawi ya kukwera kwakukulu.
Mtundu wachiwiri wa SPD imapereka chitetezo ku magawo ogawa magetsi, pothana ndi mafunde otsala omwe angakhalepo pambuyo pa chitetezo cha Mtundu 1. Ma SPD a Mtundu 2, omwe amaikidwa pamapanelo ogawa kapena ma sub-panels, amapangidwa kuti azisamalira mafunde otsika, nthawi zambiri mpaka 20-40 kA pa gawo lililonse. Zipangizozi zimaphatikizapo zigawo monga Metal Oxide Varistors (MOVs) kapena Gas Discharge Tubes (GDTs) kuti apereke chitetezo chokwanira ku zida pambuyo pa chitetezo chachikulu cha mafunde.
T1+T2 SPD Zimaphatikiza ubwino wa ma SPD a Mtundu 1 ndi Mtundu 2, zomwe zimapereka chitetezo chokwanira pamakina onse amagetsi. Mwa kuyika Type 1 SPD pakhomo lalikulu lamagetsi kuti ithane ndi kukwera kwamphamvu kwamagetsi ndi Type 2 SPD mkati mwa makina ogawa kuti atetezedwe kachiwiri, ma SPD a T1+T2 amatsimikizira chitetezo champhamvu ku mitundu yosiyanasiyana ya kukwera kwamagetsi. Njira yophatikizana iyi ndi yabwino kwambiri m'malo omwe ali pachiwopsezo chachikulu monga malo osungira deta, zipatala, ndi mafakitale, komwe chitetezo chokwanira cha kukwera kwamagetsi ndikofunikira.
Ngati zipangizo zambiri zotetezera ma surge (SPD) zikufunika kuti ziteteze kuyika, ndikofunikira kuti zigwirizane kuti zigwire ntchito limodzi bwino. Ngati ma SPD achokera kwa opanga osiyanasiyana, ndikofunikira kuonetsetsa kuti akugwirizana. Wokhazikitsa ndi opanga zidazi ndi omwe amapereka upangiri wabwino kwambiri kuti atsimikizire kuti ma SPD azigwira ntchito bwino limodzi.
Kodi Chipangizo Choteteza cha Surge (SPDs) n'chiyani?
Chipangizo Choteteza Kuthamanga (SPD), chomwe chimadziwikanso kuti choteteza kukwera kwa magetsi, chapangidwa kuti chiteteze zida zamagetsi ku kukwera kwa magetsi ndi kukwera kwa magetsi kwakanthawi kochepa. Chimagwira ntchito ngati gawo lofunikira kwambiri mu dongosolo loteteza magetsi. SPD imalumikizidwa limodzi ndi dera loperekera magetsi la katundu yemwe imateteza, zomwe zikutanthauza kuti ingagwiritsidwe ntchito pamlingo wosiyanasiyana wa netiweki yamagetsi. Ikalumikizidwa limodzi, SPD imakhala ndi kupinga kwakukulu pansi pa mikhalidwe yabwinobwino. Komabe, pamene kukwera kwa magetsi kwakanthawi kochepa kumachitika, kupinga kwa SPD kumachepa, zomwe zimapangitsa kuti mphamvu yamagetsi isunthidwe kudzera mu chipangizocho komanso kutali ndi zida zobisika. Njirayi imathandiza kupewa kuwonongeka kwa zamagetsi zamtengo wapatali poonetsetsa kuti mphamvu yowonjezera yamagetsi ikuyendetsedwa bwino.
