Kweli nqanaba, izixhobo zokuhambisa amandla kunye nonikezelo lwamandla kunye nenkqubo yokuhambisa kushishino lwepetrochemical ngokubanzi zisebenzisa amandla e-AC enkqubo yonikezelo lwamandla e-UPS.Emva kokuba amasebe amaninzi alawulwe kwaye acutshungulwe ngamaqhekeza e-low-voltage circuit breakers, akhupha i-24V DC kunye ne-110V AC ngokusebenzisa i-AC / DC converters okanye i-transformers kunye nezinye izixhobo zokubonelela ngemithwalo yombane kwiipaneli ezihambelanayo.
I-switchboard (ibhokisi) efakwe kwishishini le-petrochemical kufuneka ifakwe ngaphakathi kunye neemeko ezilungileyo zokusingqongileyo.Ukuba ukufakwa kwangaphandle kuyadingeka, iindawo ezineemeko ezinzima kufuneka zigwenywe, kwaye iibhokisi zokuhambisa (iibhokisi) ezifanelekileyo kwimigangatho yendalo yendalo yendawo yokufakela kufuneka ikhethwe.
Ngenxa yeemfuno zokuvelisa, kukho imithwalo yempompo emininzi kwishishini lepetrochemical, kwaye imithwalo yempompo emininzi ixhotyiswe ngeziqalo ezithambileyo.Ukusetyenziswa kweziqalisi ezithambileyo kwandisa ngakumbi umxholo okhoyo ngoku weenkqubo zokuhambisa amandla kushishino lwepetrochemical.Okwangoku, uninzi lwabaqalayo abathambileyo basebenzisa i-6 i-single-pulse rectifiers ukuguqula i-AC yangoku kwi-DC, kwaye i-harmonics ephumelayo ikakhulu yi-5th, 7th kunye ne-11th harmonics.Umonakalo we-harmonics kwi-software ye-petrochemical system ibonakaliswe ngokukodwa kwingozi yobunjineli bamandla kunye nephutha lokulinganisa ngokuchanekileyo.Uphando lwezenzululwazi lubonisa ukuba i-harmonic currents iya kubangela ilahleko eyongezelelweyo kwi-transformers, enokuthi iholele ekugqithiseni, ukukhawuleza ukuguga kwezinto ezikhuselayo kunye nokukhokelela kumonakalo we-insulation.Ubukho be-pulse yangoku buya kwandisa amandla abonakalayo kwaye kube nefuthe elibi kakhulu ekusebenzeni kwe-transformer.Ngelo xesha, i-harmonics ngokuthe ngqo inefuthe elibi kwi-capacitors, i-breakers circuit, kunye nezixhobo zokukhusela i-relay kwinkqubo yamandla.Kwizixhobo ezininzi zokuvavanya, ingcambu yokwenene ithetha ixabiso lesikwere alinakulinganiswa, kodwa ixabiso eliqhelekileyo linokulinganiswa, kwaye i-imaginary waveform iphindaphindwe ngesalathisi esilungileyo ukufumana ixabiso lokufunda.Xa i-harmonics inzulu, ufundo olunjalo luya kuba nokutenxa okukhulu, okukhokelela ekuphambukeni komlinganiselo.
Iingxaki onokudibana nazo?
1. Ukuqala iingxaki zokuvuthela ezahlukeneyo kunye neepompo
2. I-converter frequency ivelisa inani elikhulu le-harmonics, elichaphazela ukusebenza okukhuselekileyo kwezixhobo zombane kwinkqubo.
3. Izohlwayo ezingasebenziyo ezibangwe kumbane ophantsi ngokwentelekiso (ngokungqinelana “neMilinganiselo yeMrhumo yoLungiso lweFactor yoMbane” eyenziwe nguMphathiswa weMithombo yaManzi noMbane wenkampani yethu kunye neBurewu yeXabiso yenkampani yethu).
4. Ishishini lepetrochemical yinkampani edla amandla amaninzi.Ngenxa yotshintsho kwimigaqo-nkqubo kunye nemimiselo yokusetyenziswa kombane yenkampani yethu, inokuchatshazelwa ngumahluko kwiintlawulo zombane.
Isisombululo sethu:
1. Fakela i-hy-type high-voltage reactive power reactive device oluzenzekelayo kwicala le-6kV, 10kV okanye i-35kV yenkqubo ukuhlawulela amandla asebenzayo enkqubo, ukuphucula umlinganiselo wamandla, ukuyila umlinganiselo wokusabela osebenzayo, kunye nokulawula ngokuyinxenye ngokuzenzekelayo inkqubo yokubetha kwangoku;
2. Icala le-high-voltage yenkqubo isebenzisa inkqubo yokubuyisela umgangatho wamandla ukubuyisela ngokukhawuleza imithwalo esebenzayo ngexesha langempela kunye nokugcina ukuthembeka komgangatho wamandla wenkqubo;
3. Isihluzo esisebenzayo i-Hongyan APF ifakwe kwicala eliphantsi-voltage 0.4kV ukulawula i-harmonics yenkqubo, kunye nesixhobo sembuyekezo ye-static yokhuseleko isetyenziselwa ukubuyisela amandla asebenzayo enkqubo yokuphucula amandla ombane.
