Zifundise ukuthi ungayisebenzisa kanjani i- ukuchithwa kwesithando somlilo

Izinga lokuqala lesithando somlilo esincibilikisa induction:

Ngaphambi kokuqala, hlola ukuthi isekethe kagesi ilungile, noma izingxenye zonakele, ukuthi indawo ngayinye yokuxhumana ixega noma inqanyuliwe.

I-Phenomenon, uma isimo esingenhla senzeka, ukunikezwa kwamandla kungavulwa ngemuva kokususwa kwephutha.

(1) Bizela abasebenzi besiteshi esincane abasemsebenzini ukuthi bavale ikhabhinethi yokushintsha isithando somlilo esincibilikayo, banike amandla isithando somlilo esincibilikayo, futhi basayine irekhodi lokudluliswa kwamandla;

(2) Gqoka amagilavu ​​futhi uvale amaswishi ayisithupha okwenziwa ngesandla ngaphansi kwekhabhinethi yokusabalalisa amandla, futhi ubheke ukuthi ingabe i-voltmeter engenayo kuphaneli iyahambisana yini nogesi wokuhlinzeka, kanye nogesi ongenayo wezigaba ezintathu udinga ukulingana;

(3) Qala i-voltmeter yolayini ongenayo ekhabetheni lokuphakela amandla ukuze ubonise amandla kagesi, ukukhanya kwenkomba yamandla (okuphuzi) kuvuliwe, nokukhanya kwesiginali yamandla okushintshashintshayo (okubomvu) kuvuliwe, qala ngokuvula i-potentiometer yamandla ngokuphambene newashi. endaweni eyiziro (kuze kube sekupheleni), bese ucindezela inverter Inkinobho yomsebenzi (eluhlaza okotshani), ukukhanya kwenkomba ye-inverter yomsebenzi (okuluhlaza) kuvuliwe, futhi i-pointer ye-voltmeter ye-DC kuphaneli yomnyango kufanele ibe ngaphansi kwesikali se-zero;

(4) Ilitha lamandla. Okokuqala, lungisa i-potentiometer yamandla ngokwewashi kancane. Ngalesi sikhathi, naka ukusungulwa kwefrikhwensi emaphakathi futhi uzwe umsindo wekhwela, okubonisa ukuthi ukunikezwa kwamandla okuvama okumaphakathi kuqaliswe ngempumelelo. Kulapho kuphela lapho i-potentiometer yamandla ingavunyelwa khona ukuthi ijikelezise kancane ngendlela yewashi, futhi ingawudonseli phezulu ngokushesha. Amandla, khulisa amandla kancane, uma imvamisa ye-IF ingakasungulwa, buyisela i-potentiometer bese uqala kabusha;

(5) Uma amandla avuliwe, uma kungekho noma umsindo ongajwayelekile kumafrikhwensi amaphakathi, akufanele aphoqwe ukuthi aqale, khona-ke i-potentiometer kufanele ihoxiswe ngokuphambene newashi kuze kube sekugcineni, bese iqalwa kabusha. Uma izikhathi eziningana zingaphumeleli, kufanele ivalwe futhi ihlolwe;

(6) Esigabeni sokuqala sokulayisha (lapho ulayisha ngokuqhubekayo ama-ingots ensimbi), amandla kufanele ashintshwe abe ngu-2000kW, ukuze i-potentiometer yokulungisa amandla ibe nomphetho (i-potentiometer akumele ilungiswe igcwale) ukuvimbela ukwanda okungazelelwe amandla kanye namanje ngenxa yenqubo yokulayisha Okuphezulu, okwenza umonakalo ku-thyristor. Ngemva kokuqedwa kokulayisha, kancane kancane wandise amandla abe ngaphezu kuka-3000kW;

(7) Ezigabeni ezimaphakathi nezakamuva zokuncibilika, amandla kufanele ehliswe abe ngu-2000kW (amandla ancishisiwe). Ngemva kokuqedwa kokugcwalisa, lungisa kancane amandla amandla abe ngaphezu kuka-3000kW ukuze uvimbele ukwanda okungazelelwe kwamandla kanye namanje ngesikhathi sokushaja. Ukulimala komthelela we-thyristor;

(8) Uma kukhona izinto zokwakha esithandweni somlilo, ungalungisi ngokugcwele i-potentiometer yamandla ngalesi sikhathi, futhi ungasebenzi ngamandla amakhulu. Amandla kufanele alawulwe ku-2000kW ukuvimbela ingots yensimbi ukuthi ingaweli esithandweni ngokuzumayo, okubangela ukwanda okungazelelwe kwamandla namandla. , Ukubangela ukulimala komthelela ku-thyristor;

(9) Phakathi nenqubo yokuncibilikisa, uma isistimu ikehla ngokuzumayo, kufanele uhlonze ngokucophelela imbangela yohambo, futhi uhlole ngokucophelela ikhabethe lamandla kanye nesistimu yamandla yamafrikhwensi aphakathi nendawo ukuze avuze, ukucindezela okuvamile, nezimpawu zokushisa. Ungaqalisi kabusha ukunikezwa kwamandla okuvama okumaphakathi ngobumpumputhe. , Ukuvimbela ukwanda kwephutha, kubangela ukulimala ohlelweni lwamandla, i-thyristor kanye nebhodi eliyinhloko;

(10) Ubudlelwano obujwayelekile phakathi kwamanje kanye ne-voltage lapho amandla elungiswa ku-potentiometer yamandla aphelele yilokhu:

IF voltage = DC voltage x 1.3

I-DC voltage = i-voltage yomugqa engenayo x 1.3

DC yamanje = umugqa ongenayo wamanje x 1.2

(11) Ngemva kokuqinisekisa ukuthi yonke into ijwayelekile ngemva kokuvala, lengisa uphawu (lokudluliswa kwamandla) kubhuleki lemanuwali.

Izinga lokucibilika kwesithando somlilo sokungeniswa

(1) Qala ngokujikisa i-potentiometer yamandla ngokuphambene newashi ukuya ekugcineni. Lapho i-ammeter ye-DC, i-DC voltmeter, imitha yefrikhwensi, i-voltmeter yefrikhwensi emaphakathi, nemitha yamandla ekhabetheni lamandla okushintshashintshayo konke kunguziro, cindezela inkinobho yokumisa inverter (bomvu), Isibani sesikhombi sokumisa isiguquli (bomvu) sivuliwe.

(2) Donsela phansi amaswishi ayisithupha okwenziwa ngesandla engxenyeni engezansi yekhabhinethi yokusabalalisa amandla, bese ulengisa uphawu (lokuhluleka kwamandla).

(3) Yazisa isiteshi esincane esisemsebenzini ukuthi sinqamule i-switchgear futhi sinqamule amandla esithandweni somlilo esincibilikayo.

(4) Ngesikhathi sokusebenza kwe-inverter power supply, izinsimbi zikagesi kufanele zirekhodwe futhi ziqashwe njengoba kudingeka. Uma izimo ezingavamile zitholakala, umshini kufanele uvalwe futhi imbangela kufanele ihlolwe ngokushesha, futhi ukusebenza kungaqhutshwa ngemva kokususwa kwephutha.

(5) Ngesikhathi sokusebenza kwe-inverter power supply, uma ukuvuza kwamanzi noma ukuvinjelwa kutholakala emzileni wamanzi kanye nezingxenye zokupholisa amanzi, umshini kufanele uvaliwe futhi uhlolwe futhi kusetshenzwe. Ngemuva kokulungisa nokomisa ngesomisi sezinwele, kungavulwa futhi kusetshenziswe futhi.

(6) Ngesikhathi sokusebenza kwamandla kagesi we-inverter, kwenqatshelwe ngokuphelele ukubheka ukutshekisa, ukucofa ukunyakazisa, kanye nemisebenzi yokuphakela ngamandla. Le misebenzi engenhla kufanele yenziwe ngemuva kokumisa ukunikezwa kwamandla kagesi we-inverter.
