KutloisisoLitšireletso tsa DC Surge: Ntho ea Bohlokoa Bakeng sa Polokeho ea Motlakase
Lefatšeng la kajeno, ka ho ata ha lisebelisoa tsa elektroniki le litsamaiso tsa matla a nchafatsoang, bohlokoa ba tšireletso ea ho phahama ha maqhubu bo ke ke ba nyenyefatsoa. Mosireletsi oa DC surge (DC SPD) ke e 'ngoe ea likarolo tsa bohlokoa tsa ho sireletsa litsamaiso tsena. Sengoloa sena se teba ka botebo moelelong, ts'ebetsong le ts'ebeliso ea mosireletsi oa DC surge, se shebane le karolo eo se e bapalang ho netefatseng nako e telele le ho tšepahala ha litsamaiso tsa motlakase.
Mosireletsi oa DC surge ke eng?
Litšireletso tsa DC surge li etselitsoe ho sireletsa lisebelisoa tsa motlakase ho tsoa ho li-voltage spikes tse bakoang ke ho otloa ke lehalima, ts'ebetso ea ho fetola, kapa liketsahalo tse ling tsa nakoana. Ho fapana le litšireletso tsa setso tsa AC surge tse sebelisoang hangata malapeng le likhoebong, litšireletso tsa DC surge li etselitsoe lits'ebetso tsa DC. Sena se li etsa hore e be tsa bohlokoa ho sireletseng litsamaiso tsa matla a letsatsi, litsamaiso tsa polokelo ea matla a betri, le lisebelisoa tse ling tse tsamaisoang ke DC.
Lisebelisoa tsa tšireletso ea DC surge li sebetsa joang?
Sesireletsi sa DC surge (SPD) se sebetsa ka ho faposa motlakase o feteletseng hole le disebediswa tse bonolo. Ha ho hlaha ho phahama, sesebediswa se lemoha keketseho ya motlakase mme se qala mokgwa wa tshireletso, hangata se sebedisa dikarolo tse kang metal oxide varistors (MOVs) kapa di-gas discharge tubes (GDTs). Dikarolo tsena di monya matla a feteletseng mme di a fetisetsa fatshe, di a thibela ho fihlella disebediswa tse hokahantsweng.
Katleho ea setšireletso sa DC surge hangata e lekanngoa ka motlakase oa eona oa ho khomarela, nako ea karabelo le bokhoni ba ho monya matla. Ha motlakase oa ho khomarela o le tlase, tšireletso e ba betere, kaha ho bolela hore sesebelisoa se ka fokotsa motlakase o fihlang sesebelisoa. Ho phaella moo, nako ea karabelo e potlakileng le eona ea bohlokoa ho fokotsa nako ea ho pepesehela surge.
Tšebeliso ea mosireletsi oa DC surge
Litšireletso tsa DC surge li bohlokoa lits'ebetsong tse fapaneng, haholo-holo lits'ebetsong tsa eneji e nchafatsoang. Mona ke tse ling tsa libaka tsa bohlokoa tseo litšireletso tsa DC surge li sebelisoang hangata ho tsona:
1. Mekhoa ea ho Hlahisa Matla a Letsatsi: Ha matla a letsatsi a ntse a fetoha mohloli o tsebahalang oa motlakase, tlhoko ea tšireletso e sebetsang ea ho phahama ha matla a letsatsi lits'ebetsong tsa photovoltaic (PV) e ntse e hola. Litšireletso tsa DC surge (SPD) li kentsoe boemong ba inverter le combiner box ho thibela ho phahama ho ka senyang liphanele tsa letsatsi le li-inverter.
2. Sistimi ea Polokelo ea Matla a Betri: Ka ho phahama ha litharollo tsa polokelo ea matla, ho bohlokoa ho sireletsa litsamaiso tsa betri ho tsoa ho li-voltage spikes. Li-DC surge protectors (SPDs) li thibela tšenyo e bakoang ke ho phahama ho ka bang teng nakong ea ho tjhaja le ho ntša tjhaja, ho netefatsa polokeho ea betri le nako e telele.
3. Lipuisano: Lipuisanong tsa mehala, li-DC SPD li sebelisoa ho sireletsa lisebelisoa tse bonolo tse kang li-router, li-switch le likhoele tsa puisano ho tsoa ho matla a motlakase a ka sitisang ts'ebeletso le ho baka ho hloleha ha lisebelisoa.
4. Likoloi tsa Motlakase (EV): Ha ho kenella ha likoloi tsa motlakase ho ntse ho eketseha, tlhoko ea tšireletso ea ho phahama ha motlakase liteisheneng tsa ho tjhaja motlakase le eona ea eketseha. Litšireletso tsa DC surge (SPD) li thusa ho sireletsa meralo ea motheo ea ho tjhaja motlakase ho tsoa ho li-voltage tse ka bang teng nakong ea ts'ebetso ea ho tjhaja motlakase.
Ka bokhutšoane
Ka bokhutšoanyane, litšireletso tsa DC surge li bapala karolo ea bohlokoa ho sireletseng litsamaiso tsa motlakase ho tsoa ho li-voltage tse senyang. Ka tsoelo-pele e tsoelang pele ea theknoloji le ho itšetleha ka ho eketsehileng ka lisebelisoa tse tsamaisoang ke DC, bohlokoa ba ho kenya tšebetsong mehato e sebetsang ea tšireletso ea li-surge bo ke ke ba hlokomolohuoa. Ka ho tsetela ho li-surge tsa DC tsa boleng bo holimo, batho ka bomong le likhoebo ba ka netefatsa polokeho, ts'epo le bophelo bo bolelele ba litsamaiso tsa bona tsa motlakase, qetellong ba fokotsa litšenyehelo tsa nako ea ho se sebetse le tsa tlhokomelo. Ha re ntse re ea bokamosong bo nang le motlakase haholoanyane, ho utloisisa le ho sebelisa tšireletso ea DC surge ho bohlokoa ho mang kapa mang ea amehang moralong, ho kenya, kapa tlhokomelong ea litsamaiso tsa motlakase.
