Kodi Chitetezo cha Surge Chingagwire Ntchito Popanda Pansi?
Choteteza mafunde sichingagwire ntchito bwino popanda kukhazikika. Kuti mutetezeke ku ma voltage spikes, onetsetsani kuti soketi yanu yakhazikika ndipo mawaya anu ali olondola.
Chifukwa Chiyani Chitetezo Chanu Cha Mphezi Chili Ndi Hafu Yokha Popanda Chitetezo Chamkati?
Chipangizo choteteza mafunde (SPD) chaukadaulo chimagwira ntchito kudzera mu njira zotumizira mphamvu zamagetsi m'magawo ambiri komanso njira zomangira mafunde. Pakati pake, chimagwiritsa ntchito zigawo monga MOVs ndi GDTs kuti chisinthe mphamvu ya mafunde mofulumira kupita pansi ndikutseka mafunde otsala mkati mwa malire otetezeka a zida zolumikizidwa. Kugwira ntchito kwake kumadalira mtundu wa zigawo, kutalika kwa lead ya nthaka, ndi chitetezo chogwirizana. Zizindikiro zazikulu za magwiridwe antchito (KPIs) monga mafunde omangira (Mmwamba) ndi nthawi ya moyo wa mafunde zimatsimikizira kudalirika kwa nthawi yayitali.
Buku Logulira Chipangizo Choteteza Surge: Malangizo Anzeru Atatu Osankhira Chochita Chenicheni
Dziwani momwe mungasankhire chipangizo chodalirika choteteza mafunde (SPD) poyesa njira zopangira, ziphaso, ndi mayeso a labu - zofunika kwambiri pachitetezo cha magetsi.
Chitetezo cha Mphezi Yamkati ndi Zipangizo Zothandizira Kuthamanga: Kodi Kusiyana N'kutani?
Chitetezo cha mkati mwa mphezi chimayang'ana kwambiri popewa nthunzi zoopsa zomwe zimayambitsidwa ndi mafunde a mphezi, makamaka kudzera mu equipotential bonding ndi insulation. Cholinga cha chitetezo cha mafunde ndi kuteteza machitidwe amkati ku mafunde oyambitsidwa ndi mphezi pogwiritsa ntchito ma SPD ogwirizana, kuteteza, kukhazikika, ndi njira zodzipatula. Mndandanda wa IEC 62305 umasiyanitsa bwino mfundo ziwirizi, ndi SPM ikulongosola za zotsatira za mafunde ndi LPS yamkati ikulongosola zoopsa za mafunde. Zonsezi pamodzi ndi zofunika kwambiri pa njira yonse yotetezera mphezi.
Kusankha Zipangizo Zoteteza Kuwonjezeka kwa Machitidwe a PV - Parameter ya SPDs
Nkhaniyi ikufotokoza momwe mungasankhire ma SPD oyenera mbali ya DC ya makina a dzuwa a padenga, ndikugogomezera kufunika kwa zipangizo za PV zokhala ndi ma voltage oyenera komanso ma current ratings. Ikufotokozanso kuti miyezo yokhazikika ndi yochepa chabe, kotero kapangidwe ka makina, kukhazikika, ndi chitetezo cha mphezi ziyenera kuganiziridwa mosamala.
Momwe Mungasankhire Moyenera Chipangizo Choteteza Kuwonjezeka (SPD)
Kusankha SPD kumafuna kuwunika kwathunthu kwa mphamvu yamagetsi ya dongosolo, chiopsezo cha mphezi, kuthekera kwa zida kupirira, komanso malo oyika.
Kusankha Zipangizo Zoteteza Kukwera kwa Machitidwe a PV - Kukhazikitsa kwa SPDs
Kupanga magetsi a Photovoltaic (PV) ndi gwero lofunika kwambiri la mphamvu zongowonjezwdwa ndipo kukupikisana kwambiri poyerekeza ndi kupanga magetsi kwachikhalidwe malinga ndi zachuma. Pakati pa mitundu yosiyanasiyana ya ma PV, makina ang'onoang'ono ogawidwa—monga kukhazikitsa ma PV padenga—ndi omwe amagwiritsidwa ntchito kwambiri.
Njira Zisanu Zotetezera Oteteza Opaleshoni
Akuti 75% ya kulephera kwa zinthu zamagetsi kumachitika chifukwa cha kusintha kwa zinthu ndi kukwera kwa zinthu. Kusintha kwa zinthu ndi kukwera kwa zinthu zamagetsi kumachitika paliponse—kaya kuchokera ku ma gridi amagetsi, kugunda kwa mphezi, kuphulika, kapena kuyenda pa kapeti, komwe kungapangitse ma volti zikwizikwi a induction yamagetsi. Zonsezi ndi zoopsa zosaoneka koma zoopsa kwambiri pazida zamagetsi.
Chifukwa chake, kuti zinthu zamagetsi zikhale zodalirika komanso kuti anthu azikhala otetezeka, njira zodzitetezera ku ma voltage transients ndi surges ziyenera kukhazikitsidwa.
Kusankha Zipangizo Zoteteza Kukwera kwa Machitidwe a PV - Mitundu ya SPDs
Makina a PV pamwamba pa denga amagwiritsa ntchito magetsi a AC ndi DC, ndipo ma voltage amafika mpaka 1500V. Makamaka, mbali ya DC—monga mapanelo a PV—ikhoza kuonekera mwachindunji kumadera omwe mphezi zimawomba, zomwe zimapangitsa kuti awonongeke kwambiri ndi mphezi. Ngakhale ma module a PV sakulephera kutetezedwa ndi magetsi chifukwa cha magetsi ochulukirapo, magwiridwe awo amagetsi angachepebe. Izi zimapangitsa kuti pakhale kufunika kwakukulu kwa chitetezo cha magetsi ochulukirapo pamakina a PV padenga.
Ma Parameter Ofunika ndi miyezo yoyesera ya Surge Protective Devices (SPDs)
Chipangizo Choteteza Kuthamanga (SPD): Chipangizo chomwe chimagwiritsidwa ntchito kuchepetsa kupitirira kwa mphamvu kwa magetsi komanso kusokoneza mafunde amagetsi.
