Phunzitsani momwe mungagwiritsire ntchito chowotcha kutentha

Muyezo woyambira wa ng’anjo yosungunuka ya induction:

Musanayambe, yang’anani ngati dera lamagetsi lili bwino, kaya zigawozo zawonongeka, ngati malo aliwonse okhudzana ndi otayirira kapena otsekedwa.

Chodabwitsa, ngati zomwe zili pamwambapa zichitika, magetsi amatha kuyatsidwa pambuyo poti cholakwikacho chichotsedwa.

(1) Itanani ogwira ntchito pa siteshoni kuti atseke kabati yosinthira ng’anjo yosungunula, kuyatsa ng’anjo yosungunula, ndi kusaina mbiri yotumizira mphamvu;

(2) Valani magolovesi ndikutseka masiwichi asanu ndi limodzi pansi pa kabati yogawa mphamvu, ndikuwona ngati voltmeter yomwe ikubwera pagawo ikufanana ndi magetsi operekera, ndipo voteji yomwe ikubwera ya magawo atatu ikufunika kuti ikhale yoyenera;

(3) Yambitsani voltmeter yomwe ikubwera pa kabati yoperekera mphamvu kuti muwonetse mphamvu yamagetsi, kuwala kwamphamvu (yachikasu) kuyatsa, ndipo kuwala kwamagetsi a inverter (kufiira) kumayatsidwa, tembenuzirani mphamvu ya potentiometer motsatana. mpaka zero malo (mpaka kumapeto), ndipo akanikizire inverter The ntchito batani (wobiriwira), inverter ntchito chizindikiro kuwala (wobiriwira) ali, ndi cholozera cha DC voltmeter pa khomo gulu ayenera kukhala pansi zero sikelo;

(4) Lita mphamvu. Choyamba, sinthani mphamvu ya potentiometer mozungulira pang’ono. Panthawiyi, tcherani khutu ku kukhazikitsidwa kwa mafupipafupi apakati ndikumva phokoso la mluzu, kusonyeza kuti magetsi apakati ayamba bwino. Pokhapokha pamene mphamvu ya potentiometer ingaloledwe kusinthasintha pang’onopang’ono molunjika, ndipo osayikoka mofulumira. Mphamvu, onjezani mphamvu pang’onopang’ono, ngati ma frequency a IF sanakhazikitsidwe, tembenuzirani potentiometer ndikuyambiranso;

(5) Mphamvu ikatsegulidwa, ngati palibe kapena phokoso losamveka pamafupipafupi apakatikati, sayenera kukakamizidwa kuti ayambe, ndiye kuti potentiometer iyenera kubwezeredwa motsatana mpaka kumapeto, ndikuyambiranso. Ngati kangapo sizikuyenda bwino, iyenera kutsekedwa ndikufufuzidwa;

(6) Pa gawo loyambirira la kutsitsa (pamene mukukweza ma ingots achitsulo mosalekeza), mphamvu iyenera kusinthidwa kukhala 2000kW, kuti potentiometer yosinthira mphamvu ikhale ndi malire (potentiometer sayenera kusinthidwa kuti ikhale yodzaza) kuti mupewe kuwonjezeka kwadzidzidzi. mphamvu ndi panopa chifukwa Mumakonda ndondomeko High, kuwononga thyristor. Pambuyo Mumakonda anamaliza, pang’onopang’ono kuwonjezera mphamvu kuposa 3000kW;

(7) Pakati ndi mochedwa magawo a smelting, mphamvu iyenera kuchepetsedwa kukhala 2000kW (kuchepa mphamvu). Kudzazidwa kukamalizidwa, pang’onopang’ono sinthani mphamvuyo kuti ikhale yoposa 3000kW kuti mupewe kuwonjezeka kwadzidzidzi kwa mphamvu ndi zamakono panthawi yolipiritsa. Kuwonongeka kwa thyristor;

(8) Ngati pali zinthu zowonjezera mu ng’anjo, musasinthe mphamvu ya potentiometer panthawiyi, ndipo musagwiritse ntchito mphamvu zambiri. Mphamvuyi iyenera kuyang’aniridwa pa 2000kW kuti zitsulo zachitsulo zisagwere mu ng’anjo mwadzidzidzi, zomwe zimayambitsa kuwonjezeka kwadzidzidzi kwa mphamvu ndi zamakono. , Kuchititsa kuwonongeka kwa thyristor;

(9) Panthawi yosungunula, ngati dongosolo likuyenda mwadzidzidzi, muyenera kudziwa bwino chomwe chimayambitsa ulendowu, ndipo yang’anani mosamala kabati yamagetsi ndi mphamvu yapakatikati yamagetsi kuti iwonongeke, kuthamanga kwabwino, ndi zizindikiro za kuyatsa. Osayambitsanso magetsi apakatikati mwakhungu. , Pofuna kupewa kufalikira kwa cholakwikacho, kuwononga mphamvu yamagetsi, thyristor ndi bolodi lalikulu;

(10) Ubale wabwinobwino pakati pa masiku ano ndi voteji pamene mphamvu isinthidwa kukhala potentiometer yamphamvu yonse ndi:

IF voteji = DC voteji x 1.3

DC voltage = voteji yomwe ikubwera x 1.3

DC panopa = mzere wolowera panopa x 1.2

(11) Mukatsimikizira kuti zonse nzabwino mukatha kutseka, gwirani chizindikiro (chotumiza mphamvu) pa brake yamanja.

Induction kusungunula ng’anjo shutdown muyezo

(1) Choyamba tembenuzani mphamvu ya potentiometer motsatira koloko mpaka kumapeto. Pamene DC ammeter, DC voltmeter, frequency mita, intermediate frequency voltmeter, ndi mita yamagetsi pa inverter power cabinet zonse zili ziro, dinani batani loyimitsa inverter (lofiira), Kuwala kwa inverter stop indicator (red) kuyatsa.

(2) Kokani masiwichi amanja asanu ndi limodzi m’munsi mwa kabati yogawa mphamvu, ndikupachika chizindikiro (kulephera kwa mphamvu).

(3) Dziwitsani ogwira ntchito pagawo laling’ono kuti atsegule chosinthira ndikudula mphamvu ya ng’anjo yosungunuka.

(4) Panthawi yogwiritsira ntchito magetsi a inverter, zida zamagetsi ziyenera kulembedwa ndi kuyang’aniridwa ngati zikufunikira. Ngati zinthu zachilendo zipezeka, makinawo ayenera kutsekedwa ndipo chifukwa chake chiyenera kuyang’aniridwa nthawi yomweyo, ndipo ntchitoyo ikhoza kupitilizidwa pambuyo pochotsa cholakwikacho.

(5) Panthawi yogwiritsira ntchito magetsi a inverter, ngati kutuluka kwa madzi kapena kutsekedwa kumapezeka m’madzi ndi zigawo zoziziritsa madzi, makinawo ayenera kutsekedwa ndikuyang’aniridwa ndi kuchitidwa. Pambuyo pokonza ndi kuyanika ndi chowumitsira tsitsi, ikhoza kutsegulidwa ndikugwiritsidwanso ntchito.

(6) Pa ntchito ya magetsi inverter ndi zoletsedwa kuchita kupendekera kuonerera, tilting pogogoda, ndi kudyetsa ntchito ndi mphamvu pa. Zochita pamwambapa ziyenera kuchitidwa pambuyo poyimitsa magetsi a inverter.
