imodeli yemveliso

usetyenziso oluqhelekileyo
Okwangoku, iimveliso eziphambili zihlulwe zibe ngamacandelo amabini: iimveliso zokulawula i-harmonic kunye neemveliso zembuyekezo yamandla asebenzayo.Amashishini abandakanyekayo: icuba, i-petroleum, amandla ombane, amalaphu, isinyithi, intsimbi, ukuhamba ngololiwe, ishishini lemichiza yeplastiki, iyeza, unxibelelwano, isikhululo sokutshaja, ishishini le-photovoltaic, uMasipala, isakhiwo kunye namanye amashishini, ezi zilandelayo ziimeko ezininzi eziqhelekileyo.
1. Ishishini lelaphu: Eyona mithwalo yi-UPS yomthamo omkhulu kunye nezixhobo zekhompyutha.I-UPS ibonelela ngomthwalo ngamandla ombane akumgangatho ophezulu kunye nokuchaneka kokuqina kombane ophezulu kunye nokuphazamiseka okuphantsi kwamaza.Nangona kunjalo, ekubeni i-UPS ingumthwalo ongeyena umgca, i-rectifier kwi-UPS ivelisa inani elikhulu le-harmonic current , ukwenzela ukuba izinga lokuphazamiseka kwangoku kwicala legridi liphezulu kakhulu, elingabangeli nje ukungcoliseka kwe-harmonic kwigridi, kodwa iphinda ithintele. igalelo eliqhelekileyo lekhabhinethi yamandla esebenzayo, kunye nolawulo lwe-harmonic kufuneka lwenziwe
2. Kwishishini lokucoca amanzi, i-motor yempompo yokungena kwamanzi iqhutywa yi-high-power frequency converter.Ekubeni i-frequency converter kufuneka iqhube ukulungiswa kwe-diode ephezulu kunye ne-high-power thyristor inverter, ngenxa yoko, i-harmonics ye-high-order yangoku iveliswa kwiisekethe zokufaka kunye nokuphuma, eziphazamisa inkqubo yokunikezelwa kwamandla.Umthwalo kunye nezinye izixhobo zombane ezikufutshane zichaphazela ukusebenza okungaqhelekanga kwesixhobo sokulinganisa, kwaye ulawulo lwe-harmonic kufuneka lwenziwe.
3. Umzi-mveliso wecuba: Umthwalo “yintambo yokubhula”.“Isixovulelo sokubhula” kukucoca ukungcola okukumagqabi ecuba ukuze kufumaneke amagqabi ecuba angenabumdaka.Le nkqubo yenziwa ngokusebenzisa iiconverter frequency and motors.Isiguquli se-frequency ngumthombo omkhulu kakhulu we-harmonic, ngoko ke izisa ungcoliseko olubi lwe-harmonic kunye nokuphazamiseka kwe-harmonic kwinkqubo, kwaye kufuneka kuqhutywe ulawulo lwe-harmonic.
4. Ishishini lomatshini wonxibelelwano: I-UPS ibe sisixhobo esiyimfuneko kwigumbi lekhompyuter, i-UPS inokubonelela ngomthwalo.
Amandla ombane akumgangatho ophezulu kunye nokuchaneka kozinzo lombane ophezulu, ukuphindaphindwa okuzinzile, kunye nokuphazamiseka kwe-waveform ephantsi, kwaye unokufikelela kunikezelo lwamandla olungaphazamisekiyo xa utshintsha nge-static bypass.Nangona kunjalo, ekubeni i-UPS ingumthwalo ongekho mgca, iya kuvelisa inani elikhulu lee-harmonics zangoku.Ngelixa igridi yamandla ibangela ungcoliseko lwe-harmonic, ikwachaphazela nezinye izixhobo ezinovakalelo kwigumbi lekhompyuter, ibangela uphazamiseko olukhulu okanye ingozi kwinkqubo yonxibelelwano.Ke ngoko, onke amagumbi ekhompyuter yonxibelelwano kufuneka ajongane nengxaki yolawulo lwe-harmonic.
5. Ukuhamba ngomzila kaloliwe: Ukuze kuphendulwe kwikhwelo lesizwe lokonga umbane kunye nokunciphisa ukusetyenziswa, inkampani yeqela le-subway yagqiba ekubeni isebenzise ii-inverters kuthutho lukaloliwe ukuze kuguqulwe amandla okonga, kwaye kwangaxeshanye iqhube ulawulo lwe-harmonic kwii-inverters.Emva kwexesha lophando, ukwenzela ukuba kuqhutywe ngcono iprojekthi yokulungiswa kokugcina amandla, iqela lagqiba ekubeni liqhube iprojekthi yokulinga kwi-Rail Transit Line 4. Phakathi kwabo, i-converter frequency ikhethwe kwiimveliso zeSchneider Co., Ltd. ., kwaye isihluzo samandla esisebenzayo sikhethwa kwiimveliso zeXi'an Xichi Power Technology Co., Ltd.
6. Insimbi ye-Metallurgical: Ngenxa yeemfuno zemveliso, izixhobo ezikwicala lesibini le-transformer kwinkqubo yokusabalalisa amandla aphantsi-i-voltage ikakhulu i-motor, kwaye i-frequency converter iqhuba i-motor ukuba isebenze.Ekubeni isakhiwo sangaphakathi somguquli we-frequency converter sisebenzisa inani elikhulu lamacandelo angabonakaliyo, inani elikhulu le-harmonics lenziwa ngexesha lokusebenza.Kukho umthwalo wempembelelo ethile ngexesha lenkqubo yokuqengqeleka kwepleyiti, kwaye inkqubo yokuvelisa ayiqhubeki, nto leyo ebangela ukuguquguquka kunye nokungaqhubeki kumbane osebenzayo/okhoyo, kunye notshintsho kumbane osebenzayo kwakhona kubangele ukuguquguquka kwangoku kwe-harmonic.
