Dzidzisa iwe maitiro ekushandisa kudonhedzwa kunyorera vira

Kutanga-up mwero we induction inonyungudika choto:

Usati watanga, tarisa kuti dunhu remagetsi rakanaka here, kana zvikamu zvakakanganisika, kana nzvimbo yega yega yekusangana yakasununguka kana kubviswa.

Phenomenon, kana mamiriro ari pamusoro akaitika, magetsi anogona kuvhurwa mushure mekunge kukanganisa kwabviswa.

(1) Shevedza vashandi vechiteshi chepasi vari pabasa kuti vavhare switch kabati yechoto chekunyunguduka, kuisa moto wekunyungudika induction, uye kusaina rekodhi rekufambisa kwemagetsi;

(2) Pfeka magirovhosi uye uvhare zvitanhatu zvemanyorero pasi pekabati yekugovera magetsi, uye tarisa kana voltmeter iri kuuya papaneti inofanana nemagetsi ekupa, uye matatu-chikamu chinopinda voltage chinodiwa kuti chienzane;

(3) Tanga iyo inouya mutsara voltmeter pamagetsi emagetsi kabati kuratidza magetsi emagetsi, mwenje-pachiratidzo chemwenje (yero) wakabatidzwa, uye inverter yemagetsi chiratidzo mwenje (tsvuku) yakabatidzwa, tanga watendeudzira simba remagetsi rinopesana newachi. kune zero chinzvimbo (kusvika kumagumo), uye dzvanya iyo inverter Bhatani rebasa (girini), iyo inverter yebasa chiratidzo mwenje (girinhi) iripo, uye pointer yeDC voltmeter pamusuwo wepaneti inofanira kunge iri pazasi zero chiyero;

(4) Lita simba. Kutanga, gadzirisa simba potentiometer neclockwise zvishoma. Panguva ino, teerera kune kugadzwa kwepakati frequency uye inzwa kurira kwemuridzo, zvichiratidza kuti yepakati frequency simba rekupa yakatangwa zvinobudirira. Ipapo ndipo panogona kutenderwa simba rekuti potentiometer kuti ritenderere zvishoma nezvishoma munzira yewachi, uye kwete kurikwevera kumusoro nekukurumidza. Simba, wedzera simba zvishoma nezvishoma, kana IF frequency isati yasimbiswa, shandura potentiometer kumashure uye tangazve;

(5) Kana simba rikavhurwa, kana pasina kana ruzha rusina kujairika pane yepakati frequency frequency, haifanirwe kumanikidzwa kutanga, ipapo iyo potentiometer inofanira kudzoserwa pakatarisana kusvika kumagumo, uye yozotangazve. Kana kakawanda dzikasabudirira, inofanira kuvharwa uye kuongororwa;

(6) Padanho rekutanga rekutakura (kana uchiramba uchitakura ingots dzesimbi), simba rinofanira kugadziriswa kusvika ku2000kW, kuitira kuti simba rekugadzirisa potentiometer rive nemargin (iyo potentiometer haifaniri kuchinjwa kuti izere) kudzivirira kuwedzera kamwe kamwe. simba uye ikozvino nekuda kwekurodha maitiro Pamusoro, zvichikonzera kukuvadza kune thyristor. Mushure mekurodha kwapera, zvishoma nezvishoma wedzera simba kune anopfuura 3000kW;

(7) Pakati nepakati uye yekupedzisira matanho ekunyungudika, simba rinofanira kuderedzwa kusvika 2000kW (rakaderedzwa simba). Mushure mekunge kuzadza kwapera, zvishoma nezvishoma gadzirisa simba kune anopfuura 3000kW kudzivirira kuwedzera kamwe kamwe kwesimba uye ikozvino panguva yekuchaja. Kukanganisa kukanganisa kwe thyristor;

(8) Kana pane kuvakwa kwezvinhu muchoto, usagadzirisa zvizere simba re potentiometer panguva ino, uye usashande nesimba guru. Simba rinofanira kudzorwa pa 2000kW kudzivirira ingots dzesimbi kuti dzirege kuwira muchoto kamwe kamwe, zvichikonzera kuwedzera kamwe kamwe kwesimba uye ikozvino. , Kukonzera kukanganisa kukanganisa kune thyristor;

(9) Munguva yekunyungudutsa, kana sisitimu ikangoerekana yafamba, iwe unofanirwa kunyatso tarisa chikonzero cherwendo, uye nyatso tarisa kabati yemagetsi uye yepakati frequency simba system yekuvuza, yakajairika kudzvanywa, uye zviratidzo zvekudzima. Usatangirezve magetsi epakati ma frequency neupofu. , Kudzivirira kuwedzera kwechikanganiso, kukonzera kukanganisa kumagetsi emagetsi, thyristor uye bhodhi guru;

(10) Hukama hwakajairwa pakati pezvino uye voltage kana simba ragadziriswa kune yakazara simba potentiometer ndeiyi:

IF voltage = DC voltage x 1.3

DC voltage = inouya mutsetse voltage x 1.3

DC yazvino = mutsara unouya ikozvino x 1.2

(11) Mushure mekusimbisa kuti zvese zvakajairika mushure mekuvhara, sungirira chiratidzo che (simba rekutumira) pabhureki remanyorero.

Induction yakanyunguduka choto shutdown standard

(1) Kutanga shandura simba potentiometer counterclockwise kusvika kumagumo. Kana iyo DC ammeter, DC voltmeter, frequency meter, yepakati frequency voltmeter, uye simba mita pane inverter magetsi kabati zvese zviri zero, tinya inverter stop bhatani (tsvuku), Iyo inverter stop indicator mwenje (tsvuku) iripo.

(2) Dhonza masiwichi matanhatu echinyorwa pazasi pekabati yekugovera magetsi, uye sungirira chiratidzo che (simba rekutadza).

(3) Zivisa chiteshi chevashandi kuti vabvise switchgear uye vadzime simba kune induction inonyungudika choto.

(4) Panguva yekushanda kwemagetsi e-inverter, zvigadzirwa zvemagetsi zvinofanira kunyorwa uye kuongororwa sezvinodiwa. Kana mamiriro asina kujairika akawanikwa, muchina unofanirwa kuvharwa uye chikonzero chinofanirwa kuongororwa nekukurumidza, uye oparesheni inogona kuenderera mberi mushure mekunge kukanganisa kwabviswa.

(5) Munguva yekushanda kwemagetsi inverter, kana mvura inoputika kana kuvhara kunowanikwa mumvura uye mvura-inotonhorera zvikamu, muchina unofanirwa kuvharwa uye kuongororwa uye kugadziriswa. Mushure mekugadzirisa uye kuomeswa nevhudzi rebvudzi, rinogona kuvhurwa uye kushandiswa zvakare.

(6) Munguva yekushanda kweiyo inverter magetsi emagetsi, zvinorambidzwa zvachose kuita kutarisa kwekurerekera, tilting tapping, uye kudyisa mashandiro ane simba. Mabasa ari pamusoro anofanirwa kuitwa mushure mekumisa inverter magetsi.
