Rodha harmonic maitiro;epakati frequency kunyungudutsa mavira anowedzera uye zvakanyanya kushandiswa mukunyungudutsa, kukanda uye mamwe maindasitiri.Nekudaro, kana uchishanda, iyo yepakati frequency yemagetsi vira inotora kugadzirisa uye inverter tekinoroji, zvichikonzera huwandu hukuru hweazvino uye voltage harmonics.Harmonic kusvibiswa kune simba rekupa sisitimu inoita kuti midziyo chaiyo ishande mukukanganisa uye inowedzera kurasikirwa kwemagetsi ekushandisa.Iyo yemagetsi sisitimu yepakati frequency induction furnace yakakura pulse ikozvino sosi mumagetsi emagetsi system, uye kune kazhinji chinja magetsi epakati ma frequency induction furnaces uye yakakwira frequency induction furnaces.Kazhinji, 6 single-pulse yepakati frequency induction furnaces inonyanya kuburitsa hunhu hunoenderana hwe5, 7, 11, uye 13 nguva.Kune gumi nemaviri single-pulse converter yepakati frequency induction furnaces, makiyi eharmonics ndeye 11th, 13th, 23rd uye 25th hunhu harmonics.Kazhinji kutaura, 6 pulses anoshandiswa kune madiki ekushandura midziyo, gumi nemaviri pulses anoshandiswa kune hombe converter michina, senge Y/△/Y type furnace transformer, kana maviri echoto shandurudzo anoshandiswa kune magetsi system.
Zvinoenderana nezvinetso zvinosanganikwa nazvo muzviitiko zvinoshanda, iyo harmonic mwando yemukati yepakati frequency furenace iri pasi pe85%, asi sisitimu yekuchengetedza zvigadzirwa zvinonyanya kutungamirwa neharmonics, kuvandudzwa kweharmonics kunogona kufuratirwa, uye simba rekuchengetedza simba. kwete kugutsa.Chii chakanyanya kuoma ndechekuti simba reharonic rinopfuura iro rinotenderwa rekuchengetedza simba uye kuchengetedzwa kwezvakatipoteredza midziyo, uye zviri nyore kukuvadzwa mushure mekushandisa kwenguva refu, uye tsaona dzinowanzoitika.Naizvozvo, mukupindura kune chishuwo chekukurumidzira chezvigadzirwa zvakawanda zvekupedzisira, kuchengetedza kwezvakatipoteredza uye kuchengetedza kwesimba kwepakati frequency furnaces rave dambudziko renguva refu muindasitiri yekushandiswa kwesimba, izvo zvinokanganisa maindasitiri mazhinji nemabhizinesi.
1. Iyo yepakati frequency furnace inoburitsa huwandu hukuru hwemaharmoni panguva yekushandiswa, uye kusvibiswa kweharmonic mugedhi remagetsi kunova kwakanyanya.
2. Harmonics inoderedza kugona kwekufambiswa kwemagetsi uye kushandiswa, kupisa midziyo yemagetsi, kugadzira vibration uye ruzha, kushata kwekudzivirira, kuderedza hupenyu, uye kunyangwe kusashanda uye kupisa kunze.
3. Harmonics inokonzeresa yemuno parallel resonance uye nhevedzano resonance yesimba system,
4. Kurisa zvirimo harmonic, kupisa kunze capacitance muripo midziyo uye zvimwe midziyo;
5. Harmonics inokonzera relay kuchengetedza uye otomatiki mudziyo kusashanda zvakanaka;
5. Kunze kwesimba remagetsi, harmonics inopindira zvakanyanya nemidziyo yekukurukurirana uye zvigadzirwa zvemagetsi.
6. Kana simba racho risingasviki nemitemo ye0.90 yehofisi yemagetsi, chirango chekugadzirisa mari yemagetsi chichaiswa.
7. Iyo yakaderera simba chinhu chepakati-frequency induction furnace uye huwandu hukuru hwekuremerwa mutoro unopiwa neakakosha transformer inowedzera mutoro pane transformer.
8. Panewo mamiriro ezvinhu: simba revamwe vatengi 'intermediate frequency induction furnaces harina kuderera pavanenge vakaiswa mukushanda, uye vanongoda kudzora pulse ikozvino.
Naizvozvo, kuvandudza kunaka kwesimba repakati frequency choto chave kiyi yemhinduro.Mhinduro dzekusarudza kubva:
chirongwa 1
Centralized manejimendi (isa harmonic mafirita mukamuri yekugovera magetsi yakakodzera kushanda panguva imwe chete yeakawanda epakati frequency emagetsi emagetsi)
1. Shandisa harmonic control bazi (5, 7, 11 sefa) + reactive simba regulation bazi.Mushure mesefa yekubhadhara mudziyo waiswa mukushanda, iyo harmonic control uye reactive simba muripo weiyo magetsi system inosangana nezvinodiwa.
2. Adopt inoshanda sefa (bvisa kurongeka kwesimba rinosimba) uye harmonic countermeasure bazi redunhu (5, 7, 11 odha sefa) # + isingashande kugadzirisa bazi redunhu, uye mushure mekupa kune sefa muripo wemidziyo, isa mberi Chikumbiro chemuripo usina kukodzera iyo magetsi system.
Scenario 2
Pa-saiti manejimendi (seta pa-saiti yakakwira-odha harmonic kusefa mudziyo padivi pesimba remagetsi repakati frequency furefu)
1. Gamuchira anti-harmonic bypass (5th, 7th, 11th sefa), tevera otomatiki mashandiro echoto chepakati frequency, gadzirisa maharmonics panzvimbo, uye usakanganisa kushanda kwemimwe michina panguva yekugadzira, uye maharmonics haasvike. chiyero mushure mekushandiswa.
2. Adopt active filter (bandwidth adjustment unit) uye filter bypass circuit (5th, 7th filter), iyo yakakwirira-yakarongeka harmonics mushure mekushandura haisviki chiyero.
Sarudzo 3:
Inoratidzira yedu yepamusoro yekudzokorora kudzora yakakwirira simba rinoshanda simba sefa.Yedu Hongyan APF simba kumira-yega ine 100A, 200A, 300A, 500A uye zvimwe zvakatemwa, uye 6 mayunitsi anogona kufananidzwa.Inobata kubatana kwese frequency pairs.
