Panguva ino, magetsi ekugovera magetsi uye magetsi uye kugovera sisitimu muindasitiri yepetrochemical inowanzo shandisa iyo AC simba reUPS magetsi ekupa system.Mushure mekunge matavi mazhinji achidzorwa uye kugadziridzwa neakadzika-voltage circuit breakers, anoburitsa 24V DC uye 110V AC kuburikidza neAC/DC converters kana matransformer nemimwe michina yekupa mitoro yemagetsi kumapanera anoenderana.
Iyo switchboard (bhokisi) yakaiswa muindasitiri yepetrochemical inofanira kuiswa mukati meimba ine yakanaka mamiriro ekunze.Kana kuiswa kwekunze kuchidikanwa, nzvimbo dzine hutsinye nharaunda dzinofanira kudziviswa, uye mabhokisi ekugovera (mabhokisi) akakodzera kune yakasarudzika mamiriro enzvimbo yekuisa anofanirwa kusarudzwa.
Nekuda kwezvinodiwa zvekugadzira, kune akawanda pombi mitoro muindasitiri yepetrochemical, uye mitoro yakawanda yepombi ine zvinyoro zvekutanga.Iko kushandiswa kwezvinyoro zvinyoro kunowedzera kuwedzera pulse ikozvino yemukati yemagetsi ekugovera michina masisitimu muindasitiri yepetrochemical.Parizvino, matangi akapfava akawanda anoshandisa 6 single-pulse rectifiers kushandura AC yazvino kuita DC, uye zvinokonzeresa harmonics zvinonyanya 5th, 7th uye 11th harmonics.Kukuvadza kweharmonics mu petrochemical system software inonyatso kuratidzwa mukukuvadza kumagetsi einjiniya uye kukanganisa kwechiyero chaicho.Tsvagiridzo yesainzi inoratidza kuti harmonic currents inokonzeresa kumwe kurasikirwa kune vashanduri, izvo zvinogona kutungamira mukupisa, kukurumidza kuchembera kwezvinhu zvinodzivirira uye zvinotungamira mukukuvadzwa kwekudzivirira.Kuvapo kwepulse ikozvino kuchawedzera simba rinoratidzika uye kuva nemigumisiro yakaipa pakubudirira kweshanduro.Panguva imwecheteyo, harmonics yakananga ine kukanganisa kwakashata pane capacitors, circuit breakers, uye relay kuchengetedza midziyo musimba remagetsi.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. Kutanga matambudziko ezviputi zvakasiyana-siyana nemapombi
2. Iyo frequency converter inogadzira nhamba yakakura yeharmonics, iyo inokanganisa kushanda kwakachengeteka kwemidziyo yemagetsi muhurongwa.
3. Mafaindi asina kunaka anokonzerwa nemagetsi mashoma (maererano ne "Power Factor Adjustment Electricity Fee Measures" yakagadzirwa neBazi reMvura neMagetsi eMagetsi ekambani yedu uye Price Bureau yekambani yedu).
4. Indasitiri yepetrochemical ikambani inopedza simba.Nekuda kwekuchinja kwemitemo nemirairo yekambani yedu yekushandisa magetsi, inogona kukanganiswa nekusiyana kwemitengo yemagetsi.
Mhinduro yedu:
1. Isa hy-type high-voltage reactive power automatic compensation equipment pa6kV, 10kV kana 35kV side of the system kubhadhara system reactive power, kuvandudza simba remagetsi, kugadzira kunobudirira reactance rate, uye zvishoma nezvishoma kudzora system pulse current;
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 yakaiswa pane yakaderera-voltage 0.4kV parutivi kuti itarise system harmonics, uye iyo static kuchengetedza muripo mudziyo inoshandiswa kutsiva reactive simba rehurongwa kuvandudza simba chinhu.
