Kuitira kuzadzisa zvinodikanwa zvezvikepe zvakakura uye zvepakati uye kubatanidzwa kwehupfumi hwenyika, pamwe nezvipingamupinyi zvekusimudzira hupfumi nemagariro pane zviwanikwa uye zvakatipoteredza uye kusimudzira budiriro yezvakatipoteredza mumahombekombe emahombekombe, kusimudzira uye dhizaini yemvura yakadzika. nzira uye nzvimbo dzekupaka, uye dhizaini yemichina yekufambisa yechiteshi Hukuru-hukuru uye hunyanzvi, ruzivo uye kutonga kubatanidzwa mukutarisira chiteshi, kusimudzira kwakarongeka kunoenderana nehunhu hwemhando dzakasiyana dzezvinhu, hukuru, hungwaru uye ecological masisitimu ndiwo zvinhu zvakakosha zveramangwana rekugadzirisa chiteshi uye hunyanzvi.
Nekuda kwezvinodiwa zvekugovera, kune huwandu hukuru hwendege crane mitoro muindasitiri yekurodha senge madoko, uye inverters akaiswa pamitoro yakawanda.Huwandu hukuru hwema frequency converters anowedzera zvakanyanya harmonic zvirimo musimba rekugovera sisitimu yeindasitiri yechiteshi.Parizvino, maitiro ekugadzirisa evazhinji inverters anoshandisa matanhatu-pulse rectification kushandura AC simba kuita DC simba, saka maharmonics anogadzirwa anonyanya kuve yechishanu, yechinomwe, uye yegumi neimwe harmonics.Kukuvadza kweharmonics mu petrochemical system software inonyatso kuratidzwa mukukuvadza kumagetsi einjiniya uye kukanganisa kwechiyero chaicho.Zvidzidzo zvakaratidza kuti harmonic currents ichakonzera kumwe kurasikirwa mu transformer, izvo zvinokonzeresa kupisa, kukurumidza kuchembera kweiyo insulating medium, uye kukonzeresa kukanganisa.Kuvapo kweharmonics kunowedzera simba rinoratidzika uye kune kukanganisa kukuru kwekushanda kweshanduro.Uye zvakare, iyo pulse ikozvino ine yakananga yakashata kukanganisa kune capacitors, disconnectors uye relay kuchengetedza midziyo mumagetsi ekupa system.Kune akawanda ezviridzwa zvekuyedza, iyo chaiyo mudzi inoreva square value haigone kuyerwa, asi avhareji kukosha inogona kuyerwa, uyezve yekufungidzira waveform inowedzerwa neiyo yakanaka index kuti uwane kukosha kwekuverenga.Kana iyo harmonics yakakomba, kuverenga kwakadaro kuchava nekutsauka kukuru, zvichikonzera kuyerwa kwechiyero.
Matambudziko aungasangana nawo?
1. Matambudziko ekutanga eakasiyana siyana endege cranes nemapombi
2. Iyo frequency converter inoburitsa nhamba yakakura yeharmonics, iyo inokanganisa kushanda kwakachengeteka kwemidziyo yemagetsi yehurongwa.
3. Reactive simba chirango chinokonzerwa neakaderera simba chinhu (maererano neiyo simba factor mvura uye magetsi mubhadharo wekugadzirisa nzira yakagadzirwa neBazi reMvura Zviwanikwa uye Magetsi Power yekambani yedu uye Price Bureau yekambani yedu);
Mhinduro yedu:
1. Isa HD yakakwira-voltage reactive simba otomatiki muripo wemidziyo pa6kV, 10kV kana 35kV kudivi resisitimu kutsiva reactive simba rehurongwa, kuvandudza simba remagetsi, gadzira iyo inoshanda reactance rate, uye zvishoma otomatiki kudzora pulse ikozvino. yehurongwa;
2. Iyo yepamusoro-voltage side yegadziriro inoshandisa simba rehutano dynamic recovery system kuti iite dynamically kubhadhara mitoro inoshandiswa munguva chaiyo uye kuchengetedza kuvimbika kwehutano hwemagetsi ehurongwa;
3. Iyo inoshanda sefa Hongyan APF automatic control system pulse current yakaiswa padivi rezasi voltage 0.4kV, uye iyo static data security compensation equipment Hongyan TSF compensation system software reactive load inosarudzwa kuvandudza simba chinhu.
