Ho netefatsa Tšireletseho le Ts'ebetso: Tataiso ho DC-Side Connection Wiring ho Household Energy Storage Inverters.

 

Ha litsamaiso tsa polokelo ea matla a malapa li ntse li tsebahala haholo, ho netefatsa polokeho le ts'ebetso ea lithapo tsa bona, haholo-holo ka lehlakoreng la DC, ke tsa bohlokoa. Khokahano e tobileng ea hona joale (DC) lipakeng tsa liphanele tsa letsatsi, libeteri, le li-inverters li bohlokoa bakeng sa ho fetolela matla a letsatsi hore e be motlakase o ka sebelisoang le ho o boloka hantle. Tataiso ena e fana ka kakaretso ea lintlha tsa bohlokoa, mekhoa e metle, le liphoso tse tloaelehileng tseo u lokelang ho li qoba ha u kenya le ho boloka lithapo tsa khokahanyo tsa DC li-inverters tsa polokelo ea matla a ntlo.

Ho Utloisisa Lehlakore la DC la Li-Inverters tsa polokelo ea Matla a Ntlo

Lehlakoreng la DC la inverter ea polokelo ea matla ke moo motlakase o tobileng o phallang lipakeng tsa liphanele tsa letsatsi le banka ea betri pele o fetoloa ho ba alternating current (AC) bakeng sa tšebeliso ea malapa. Lehlakore lena la sistimi le bohlokoa hobane le sebetsana ka kotloloho le phepelo ea matla le polokelo.

Sebakeng se tloaelehileng sa matla a letsatsi, liphanele tsa letsatsi li hlahisa motlakase oa DC, o tsamaeang ka likhoele le likarolo tse ling ho tjhaja libeteri. Matla a bolokiloeng ka har'a libeteri le ona a ka sebopeho sa DC. Joale inverter e fetola motlakase ona o bolokiloeng oa DC hore e be matla a AC ho fana ka lisebelisoa tsa ntlo.

Likarolo tsa bohlokoa tsa lehlakore la DC li kenyelletsa:

Lithapo tsa letsatsi tsa PV tse tsamaisang motlakase ho tloha liphanele ho ea ho inverter le betri.
Lihokelo tse hokahanyang likhoele le lisebelisoa, tse netefatsang phetisetso e bonolo ea matla.
Li-Fuse le li-switches bakeng sa polokeho, ho laola le ho hakolla matla ha ho hlokahala.

Lintlha Tse ka Sehloohong Tsa Tšireletso bakeng sa Wiring ea DC-Side

Mehato e nepahetseng ea polokeho bakeng sa wiring ea khokahanyo ea DC-lehlakoreng e bohlokoa ho thibela likotsi tsa motlakase le ho netefatsa ts'ebetso ea nako e telele. Lintlha tse ling tsa bohlokoa tseo u lokelang ho li hopola ke tsena:

Insulation ea Cable le Sizing: Ho sebelisa likhoele tse nang le mohatsela o nepahetseng ho thibela ho lutla ha motlakase le ho fokotsa kotsi ea li-circuits tse khutšoane. Tekanyo ea thapo e tlameha ho ts'oana le mojaro oa hajoale ho thibela mocheso o feteletseng le ho theoha ha motlakase, tse ka senyang ts'ebetso ea sistimi le ho baka tšenyo.

Polarity e nepahetseng: Lits'ebetsong tsa DC, ho khutlisa polarity ho ka baka ho hloleha kapa ho senyeha ha lisebelisoa. Ho bohlokoa ho etsa bonnete ba hore likhokahano tsa terata li nepahetse ho qoba ho se sebetse hantle haholo.

Tšireletso ea Overcurrent: Overcurrent e ka senya likarolo tsa motlakase tse hlokolosi 'me ea baka mollo. Sireletsa tsamaiso ka ho sebelisa li-fuse le li-circuit breakers tse lumellanang le phallo ea hona joale ho DC-side wiring.

Ho theola fatše: Ho beha fatše ho nepahetseng ho tiisa hore metsi leha e le afe a khelohileng a lebisoa lefatšeng ka mokhoa o sireletsehileng, ho fokotsa kotsi ea ho tsosoa ke motlakase le ho netefatsa botsitso ba tsamaiso. Litlhoko tsa motheo li fapana ho ea ka linaha empa kamehla li tlameha ho lateloa ka thata.

Mefuta ea Lithapo Tse Sebelisoang Bakeng sa Khokahano ea DC-Side

Ho khetha likhoele tse nepahetseng bakeng sa likhokahano tsa DC-lehlakoreng ho bohlokoa bakeng sa polokeho le ts'ebetso. Mefuta e meng e tloaelehileng e kenyelletsa:

Lithapo tsa Solar PV (H1Z2Z2-K, UL ​​4703, TUV PV1-F)**: Lithapo tsena li etselitsoe ho sebelisoa ka ntle 'me li hanyetsana le mahlaseli a UV, mocheso o phahameng, le khatello ea tikoloho. Li na le boemo bo phahameng ba ho feto-fetoha ha maemo, ho etsa hore e be tse loketseng bakeng sa lisebelisoa tsa matla a letsatsi.

Mamello e Phahameng ea Mocheso: Lithapo tsa DC-lehlakoreng li tlameha ho khona ho mamella mocheso o phahameng o hlahisoang ke phallo e sa khaotseng ea motlakase ho tloha liphanele tsa letsatsi ho ea ho inverter, haholo-holo nakong ea khanya ea letsatsi.

Boleng bo netefalitsoeng: Ho sebelisa likhoele tse netefalitsoeng ho netefatsa ho latela litekanyetso tsa polokeho mme ho thusa ho thibela liphoso tsa sistimi. Kamehla khetha lithapo tse lumellanang le maemo a IEC, TUV, kapa UL.

Mekhoa e Molemo ka ho Fetisisa ea ho Kenya Wiring ea DC-Side

Ho netefatsa polokeho le ts'epahalo lits'ebetsong tse lehlakoreng la DC, latela mekhoa ena e metle:

Cable Routing: Tsamaisa ka nepo 'me u sireletse likhoele tsa DC ho fokotsa ho pepesehela maemo a leholimo le tšenyo ea 'mele. Qoba ho kobeha ho hlabang, ho ka senyang lithapo le ho baka tšenyo e ka hare ka nako.

Ho fokotsa Voltage Drop: Ho boloka likhoele tsa DC li le khuts'oane kamoo ho ka khonehang ho fokotsa ho theoha ha motlakase, ho ka senyang ts'ebetso ea sistimi. Haeba maeto a malelele a ke ke a qojoa, eketsa boholo ba cable ho lefa.

Ho Sebelisa Lihokelo tse Loketseng: Netefatsa hore lihokelo ha li sireletsehe ho boemo ba leholimo 'me li lumellana le likhoele tse sebelisoang. Lihokelo tsa boleng bo tlase li ka baka tahlehelo ea matla kapa tsa baka likotsi tsa mollo.

Tlhokomelo le Tlhokomelo ea Kamehla: Hlahloba likhoele tsa DC khafetsa hore na ha li senyehile, ho kenyeletsoa le ho senyeha, lihokelo tse hlephileng le matšoao a ho bola. Tlhokomelo ea kamehla e ka thibela litaba tse nyane hore li fetohe mathata a maholo.

Liphoso Tse Tloaelehileng Tsa ho Qoba ho DC Wiring

Esita le mekhoa e entsoeng hantle e ka hlōleha ka lebaka la liphoso tse bonolo ts'ebetsong ea ho kenya. Qoba maraba ana a tloaelehileng:

Lithapo tse Nyenyane kapa tsa Boleng bo Tlase: Ho sebelisa lithapo tse nyane haholo bakeng sa mojaro oa hajoale oa sistimi ho ka baka mocheso o feteletseng, tahlehelo ea matla, esita le mollo. Kamehla khetha likhoele tse ka sebetsanang le tlhahiso e felletseng ea matla a sistimi ea hau.

Polarity e sa nepahalang: Ho khutlisetsa polarity tsamaisong ea DC ho ka baka tšenyo ea likarolo kapa ho hloleha ho felletseng ha sistimi. Lekola likhokahano habeli pele o matlafatsa sistimi.

Li-Cables tse Petetsanoang: Lithapo tse petetsaneng li ka etsa hore lithapo li futhumale ho feta tekano. Netefatsa sebaka se nepahetseng le moea o kenang, haholo-holo libakeng tse koaletsoeng joalo ka mabokose a mateano.

Ho hlokomoloha Likhoutu tsa Sebaka: Sebaka ka seng se na le likhoutu tsa eona tsa polokeho ea motlakase, joalo ka NEC ho litekanyetso tsa US kapa IEC machabeng. Ho hloleha ho latela tsena ho ka lebisa ho hloleheng ha sistimi kapa litaba tsa molao.

Ho lumellana le Melao le Melao ea Machaba

Sistimi ea polokelo ea matla, ho kenyeletsoa lithapo tsa bona tsa DC-side, li tlameha ho latela litekanyetso tse fapaneng tsa machabeng ho netefatsa ts'ebetso e bolokehileng le e tšepahalang:

Maemo a IEC: Litekanyetso tsa International Electrotechnical Commission (IEC) li fana ka tataiso ea lefats'e bakeng sa polokeho ea motlakase le ts'ebetso.

NEC (Khoutu ea Naha ea Motlakase): NEC e fana ka melao le melaoana ea ho kenya motlakase US. Ho latela litataiso tsa NEC ho netefatsa polokeho le tumellano.

Ho ikamahanya le maemo ana ha se taba ya polokeho feela; hangata ke tlhokahalo bakeng sa ts'ireletso ea inshorense 'me e ka ama ho tšoaneleha ha sistimi bakeng sa likhothaletso le litheolelo.

Ho beha leihlo le ho boloka likhokahano tsa DC-Side

Le litsamaiso tse kentsoeng hantle ka ho fetesisa li hloka tlhahlobo le tlhokomelo khafetsa ho netefatsa ts'ebetso e phahameng. Mona ke mokhoa oa ho lula u le mafolofolo:

Litlhahlobo tsa Kamehla: Rulahanya nako le nako ho hlahloba tšenyo ea 'mele, ho senyeha le ho senyeha ha likhokahano. Sheba matšoao a ho bola, haholo-holo libakeng tsa ka ntle.

Ts'ebetso ea Ts'ebetso ea Ts'ebetso: Li-inverter tse ngata li tla le lits'ebetso tsa ho beha leihlo tse hahelletsoeng tse lumellang basebelisi ho lekola tlhahiso le tšebeliso ea matla. Lisebelisoa tsa ho beha leihlo li ka u hlokomelisa ka mathata a kang tahlehelo ea matla e sa lebelloang, e ka supang hore ho na le bothata ba lithapo.
