Zifundise indlela yokusebenzisa i ukuchithwa kwesithando somlilo

Umgangatho wokuqalisa wesithando sokunyibilikisa soveliso:

Ngaphambi kokuba uqalise, khangela ukuba isekethe yombane ilungile, ingaba izinto zonakele, nokuba indawo nganye yoqhagamshelwano ikhululekile okanye iqhawukile.

I-Phenomenon, ukuba le meko ingentla iyenzeka, ukunikezelwa kwamandla kunokuvulwa emva kokuba iphoso isuswe.

(1) Biza abasebenzi besikhululo esincinci abasemsebenzini ukuba bavale ikhabhinethi yokutshintsha kweziko lokunyibilikisa, banike amandla kwiziko lokunyibilikisa lokungeniswa, kunye nokusayina irekhodi yothumelo lwamandla;

(2) Nxiba iiglavu kwaye uvale izitshixo zezandla ezintandathu phantsi kwekhabhinethi yokuhambisa amandla, kwaye ujonge ukuba i-voltmeter engenayo kwiphaneli ihambelana nombane wokubonelela, kunye nesigaba sesithathu sombane ongenayo kufuneka ulungelelaniswe;

(3) Qalisa i-voltmeter yomgca ongenayo kwikhabhathi yonikezelo lwamandla ukubonisa amandla ombane ombane, ukukhanya kwesalathisi sombane (okutyheli) kulayitiwe, kunye nokukhanya komqondiso wombane woguqulo (obomvu) kulayitiwe, vula kuqala i-potentiometer yamandla ngokunxamnye newotshi. ukuya kwindawo ye-zero (ukuya ekupheleni), kwaye ucinezele i-inverter Iqhosha lomsebenzi (eliluhlaza), ukukhanya kwesalathisi somsebenzi we-inverter (okuluhlaza) kuvuliwe, kunye nesalathisi se-voltmeter ye-DC kwiphaneli yomnyango kufuneka ibe ngaphantsi kwesikali se-zero;

(4) Amandla eelitha. Okokuqala, lungisa i-potentiometer yamandla ngokuthe ngqo. Ngeli xesha, nikela ingqalelo ekusekweni kwe-frequency ephakathi kwaye uve isandi sokubetha umlozi, ebonisa ukuba unikezelo lwamandla ombane ophakathi luqaliswe ngempumelelo. Kulapho kuphela apho i-potentiometer yamandla inokuvunyelwa ukuba ijikeleze kancinci kwicala lewotshi, kwaye ungayitsali ngokukhawuleza. Amandla, nyusa amandla kancinci, ukuba i-IF frequency ayikasekwa, jikisa i-potentiometer kwaye uqalise kwakhona;

5 Ukuba amaxesha amaninzi awaphumelelanga, kufuneka ivalwe kwaye ihlolwe;

(6) Kwinqanaba lokuqala lokulayisha (xa ngokuqhubekayo ulayisha iingots zentsimbi), amandla kufuneka ahlengahlengiswe ukuya kwi-2000kW, ukuze i-potentiometer yohlengahlengiso lwamandla ibe nomda (i-potentiometer mayingalungiswa ngokupheleleyo) ukukhusela ukwanda ngokukhawuleza amandla kunye okwangoku ngenxa yenkqubo yokulayisha Ephakamileyo, ebangela umonakalo kwi-thyristor. Emva kokuba kugqityiwe ukulayishwa, wandise kancinci amandla ukuya ngaphezu kwe-3000kW;

(7) Kwinqanaba eliphakathi nelisemva lokunyibilikiswa, amandla kufuneka athotywe aye kuma-2000kW (amandla acuthiweyo). Emva kokuba ukuzaliswa kugqitywe, lungisa ngokukhawuleza amandla ngaphezu kwe-3000kW ukukhusela ngokukhawuleza ukunyuka kwamandla kunye nokukhoyo ngexesha lokutshaja. Umonakalo wempembelelo ye-thyristor;

(8) Ukuba kukho ukwakhiwa kwezinto kwisithando somlilo, musa ukulungelelanisa ngokupheleleyo i-potentiometer yamandla ngeli xesha, kwaye ungasebenzi kumandla aphezulu. Amandla kufuneka alawulwe kwi-2000kW ukukhusela i-ingots zetsimbi ukuba ziwele kwisithando somlilo ngokukhawuleza, kubangela ukwanda ngokukhawuleza kwamandla kunye nombane. , Ukubangela umonakalo wempembelelo kwi-thyristor;

(9) Ngexesha lenkqubo yokunyibilikisa, ukuba inkqubo ihambe ngesiquphe, kufuneka uchonge ngononophelo unobangela wohambo, kwaye ujonge ngononophelo ikhabhathi yamandla kunye nenkqubo yamandla ephakathi kwamaza okuvuza, uxinzelelo oluqhelekileyo, kunye neempawu zomlilo. Musa ukuphinda uqalise unikezelo lwamandla amaza aphakathi ngokumfameka. , Ukuthintela ukwandiswa kwesiphoso, kubangela umonakalo kwinkqubo yamandla, i-thyristor kunye nebhodi ephambili;

(10) Ubudlelwane obuqhelekileyo phakathi kwangoku kunye nombane xa umbane uhlengahlengiswa kwi-potentiometer yamandla apheleleyo yile:

UKUBA amandla ombane = DC amandla x 1.3

Umbane we-DC = umbane womgca ongenayo x 1.3

DC yangoku = umgca ongenayo wangoku x 1.2

(11) Emva kokuqinisekisa ukuba yonke into iqhelekile emva kokuvalwa, xhoma uphawu (lokuhanjiswa kombane) kwisiqhoboshi semanuwali.

Umgangatho wokuvalwa kwesithando sokunyibilikisa

(1) Qala ujike i-potentiometer yamandla echasene newotshi ukuya ekupheleni. Xa i-ammeter ye-DC, i-voltmeter ye-DC, i-frequency meter, i-voltmeter ephakathi, kunye nemitha yamandla kwikhabhathi yamandla e-inverter zonke ziyi-zero, cofa iqhosha lokumisa i-inverter (bomvu), Isibane se-inverter stop indicator (bomvu) sivuliwe.

(2) Tsala phantsi izitshixo zemanuwali ezintandathu kwindawo engezantsi yekhabhathi yokuhambisa umbane, kwaye uxhome uphawu (ukusilela kombane).

(3) Yazisa isikhululo esingaphantsi kwabasebenzi abasemsebenzini ukuba baqhawule isixhobo sokuvala kwaye banqumle umbane kwiziko lokunyibilikisa lokungeniswa.

(4) Ngethuba lokusebenza kombane wombane, izixhobo zombane kufuneka zirekhodwe kwaye zibekwe esweni njengoko zifunwa. Ukuba iimeko ezingaqhelekanga zifunyenwe, umatshini kufuneka uvalwe kwaye isizathu kufuneka sihlolwe ngokukhawuleza, kwaye umsebenzi unokuqhutyelwa emva kokuba iphoso isuswe.

(5) Ngexesha lokusebenza kombane oguquliweyo, ukuba ukuvuza kwamanzi okanye ukuvaleka kufunyenwe kwindlela yamanzi kunye nezixhobo zokupholisa amanzi, umatshini kufuneka uvalwe kwaye uhlolwe kwaye uphathwe. Emva kokulungiswa kunye nokumisa ngesomisi seenwele, inokuvulwa kwaye isetyenziswe kwakhona.

(6) Ngexesha lokusebenza kombane oguquguqukayo, akuvumelekanga ngokungqongqo ukwenza ukubonwa kwe-tilting, i-tilting tapping, kunye nemisebenzi yokutya ngamandla. Le misebenzi ingentla kufuneka yenziwe emva kokumisa unikezelo lwamandla ombane we-inverter.
