Tjheseletsa rectifier le sesebediswa lona

Ho thata ho nahana hore ho hahoe indasteri kapa mechine ntle ho tjheseletsa. E e arotsoe mefuta e 'meli: ho toba le fapanyetsana jwale.

Sebelisa DC e fana ka boleng bo phahameng ao cheseletse. Sena ke ka lebaka la ho haella ha lefela jwale, mme ka hona ho arcing fetoha tsitsitseng haholoanyane, ho fokotsa spattering ho tswa ho chesoa ha eleketrode e, tšepe tebileng ho kenella ka hare e fumana, ka ntlafala ao cheseletse matla thepa.
Ho phaella moo, thepa e kang tšepe e kentsoeng samente, phahameng-motsoako steels, lits'epe tse kopantsoeng nikele tse thehiloeng Bibeleng, koporo, thaethaniamo, ka sebelisoa bakeng sa ho tjheseletsa feela ka hona joale ka ho toba.

Ho sokolla ho fapanyetsana jwale ho ba le maqhubu a ya 50 Hz, e sa khaotseng e sebediswa tjheseletsa rectifier. Ho sebedisa khethehileng semiconductor valve le lisebelisoa taolo ka transformer e. Ho na le mefuta e sa tšoaneng ea lihlahisoa tse joalo. E mong le e ba bona ba nang le eona ka sebopeho lona e rectifying yuniti, tsitsisang unit trust bakeng sa ho sireletsa le ho ditlabelwa le matla transformer.

Tjheseletsa rectifier e sebediswa bakeng sa pukwanana selikalikoe tjheseletsa ha eleketrode qhibiliha le pulsed selikalikoe tjheseletsa, eo ho eona e thusa tšusumetso e tsoang ho ka karohano ya terata eleketrode tšepe marotholi.

Bakeng sa boiketlo, e khethehileng phetha molao tjheseletsa rectifier tjheseletsa VD transformer mofuta, ho ba le ka thōko mokgwa wa switjha. converters joalo ba tšoauoa ka tharollo mathomo botekgeniki:

• ka mefuta e fapaneng e tšoanang bakeng sa ho tjheseletsa phetoho jwale ke le boreleli;
• chesele e etsoang ka mechine khoheli shunt tshekaletseng moralo, e fana ka phetha molao phetoho ea cheseletsa, ho na le sebopeho e bonolo;
• transformer windings li entsoe ka koporo;
• ha ho na ho fallela kela;
• Cooling moeeng;
• thothetsang molelo e habonolo ile a etsa, le selikalikoe o tsitsitse;
• kwahelang sehlopha sa - H;
• dikgokelo jwale ka tsela e sireletsehileng 'me ka potlako e qala;
• ka maemo a ho tjheseletsa go tseleganya rectifier tsa mofuta ona ke ho le bonolo ho falla.

Ka linako tse ling, lapeng ho hlokahala hore a etse mosebetsi oa tjheseletsa. Boemong boo ho na le dikgetho tse peli - ho reka itokiselitse entsoeng mochine kapa etsa tjheseletsa bona rectifier ka matsoho a bona.

Karolo ea bohlokoa ke e improvised rectifier transformer bakeng sa ho fetola lenaihana mola gagamalo le ho fana ka boholo ba hlokahala 'me boleng ba cheseletsa jwale. Hokela hoa khoneha ho Network le gagamalo ea 220 V, le khumo eo ho lokelang ho fana ka 40-70 V.

Haufi le boemelong ba transformer e lokela ho solder matla thapo ka millimeters 2,5 lisekoere le bophara ba 'me a e-ba bolelele ba ka bang 5 limithara tse, bakeng sa mokhatlo oa bonolo tsa mochine tjheseletsa. Terata ke molemo ho sebelisa ho itšehla thajana habeli.

Mokhahlelo latelang - itokisetsa ho ba le lik'hebole tjheseletsa. Bakeng sa morero ona ho ke ke molemo ho sebelisa terata bonolo le e kwahelang rabara, limithara tse ka bang mabeli ka bolelele. Ka lehlakoreng le leng la kabel tlamella clothespin "matšoele" (ka linako tse ling koloi "bobebe" ka sebelisoa), ka tse ling tse kabel - pane eleketrode.

Joale u lokela ho beha hammoho le tjheseletsa rectifier. From ena e itšetlehile ka hore na sesebediswa e loketseng tshebetsong. Ka ho sebetsa, o tla halefile, joale matlo lokela ho fana le mekoti bonahatsa. Bakeng sa ho tsamaisa bonolo ka matlo le Fasten e mohele le beha mabili. Khoneha peho ea lithapo le lik'hebole ho kenya metsoako eketsehileng ka sebōpeho sa lihakisi, washers, ka masakaneng.
