Incazelo Yomkhiqizo

Ngokusetshenziswa okubanzi kweziguquli ezihlukahlukene, iziguquli zemvamisa, iziko likagesi ze-arc nezinye izinto zikagesi ezingezona umugqa, ama-harmonic currents azo avame ukweqa amanani avumelekile wezindinganiso kazwelonke ezifanele, okuthinta kakhulu ikhwalithi yamandla wegridi yamandla.
Isihlungi se-high-voltage sesethi esiphelele siyidivayisi yokuhlunga "i-passive", okungukuthi, i-reactor yokuhlunga kanye ne-high-voltage filter capacitor kuhlanganiswe ngokufanelekile.Ngemuva kokulungiswa okunembile, igatsha lokuhlunga lingakha isiteshi esine-impedance ephansi ye-harmonic ngayinye ye-high-order, ukuze i-harmonic current ehambisanayo ibe nkulu.Ingxenye yawo igelezela kusihlungi ukuze ihlunge i-harmonic current futhi inciphise izinga lokuhlanekezela kagesi we-harmonic wendawo yokufinyelela yomphakathi.Ngaphezu kwalokho, iphinde inikeze isinxephezelo samandla asebenzayo futhi ithuthukise isici samandla.
Lolu cingo lufakwe kakhulu ohlangothini lwebhasi engu-6kV, 10kV, 35kV, 110kV, futhi lufanele izindawo ezinamagagasi amakhulu avumelanayo njengamasistimu kagesi, insimbi, insimbi, izitshalo ze-aluminium, i-petroleum, imboni yamakhemikhali, izitimela zikagesi, ukwenza amaphepha kanye nokwakhiwa kwemikhumbi. .

Izici zomkhiqizo kanye nobubanzi bokusetshenziswa

1. I-capacitor yesihlungi yenziwe ngamayunithi amaningi e-capacitor, futhi i-capacitor yesihlungi esisodwa ithatha isakhiwo sesigaba esisodwa sokushuna kokuhlukaniswa kwesigaba.I-filter capacitor yamukela yonke ifilimu eyinhlanganisela ephakathi, enezici zobukhulu obuncane, ukulahlekelwa okuphansi kanye nezinga lokushisa eliphansi lokusebenza.
2. I-reactor yesihlungi isebenzisa ukwakheka kwe-air-core eyomile yesigaba esisodwa, futhi inani le-inductance lishintshwa ngokuqhubekayo ngo-5%.I-reactor ingafakwa ngokuvundlile ngesimo esithi "-" noma "pin".
3. Isakhiwo sesethi ephelele yamadivayisi okuhlunga siyaguquguquka, futhi singaba uhlobo lwekhabhinethi noma uhlobo lohlaka.Lapho isakhiwo sefreyimu samukelwa, yonke idivayisi ihlukaniswa ngocingo.
4. Idivayisi yokuhlunga iklanywe ngezindlela zokulawula okwenziwa ngesandla nezizenzakalelayo, okwenza ukusebenza kube lula futhi kuphephe.
5. Yamukela idivayisi edidiyelwe yokuvikela ezenzakalelayo yekhompyutha ukuze ulandelele izinguquko zesistimu ngesikhathi sangempela.Yenza okokusebenza kusebenze ngokuphepha nangokuthembekile.
6. Ngokwezidingo zesistimu yomsebenzisi, ingakwazi ukuhlunga ngokuphumelelayo ukuhleleka okuphezulu kwegridi yamandla, inxephezele amandla asebenzayo, futhi ithuthukise ikhwalithi ye-voltage.
Imibandela Yokusebenzisa:
1. Ukuphakama: <1000m;
2. Izinga lokushisa le-ambient: -25℃～+45℃;
3. Umswakama ohlobene: <90% ku-20℃;
4. Indawo yokufaka ayinakho ukudlidliza kwemishini okunzima, ayinawo igesi egqwalayo nesitimu, ayinakho ukuqhutshwa kukagesi futhi ayinakho uthuli oluqhumayo.

Izici zesakhiwo somkhiqizo kanye nemiyalelo yoku-oda

isakhiwo:
Iqukethe iswishi ehlukanisayo ene-voltage ephezulu, i-vacuum vacuum contactor ephezulu-voltage noma i-vacuum circuit breaker, i-transformer yamanje, uhlobo olomile lwesihlungi esingenalutho, i-zinc oxide.
Isibambisi sombani, i-capacitor yokuhlunga, i-fuse enamandla amakhulu, ikhoyili yokukhipha ugesi kanye ne-non-inductive resistor kwakhiwa ngokufanelekile idivayisi yesihlungi esishuthwe kanye noma isihlungi esidlula phezulu.
idivayisi.Idivayisi yesihlungi eshunwe kanye isetshenziswa ikakhulukazi ukuhlunga izici ezihambisanayo eziyinhloko emthonjeni we-harmonic, njenge-3rd, 5th, 7th, 11th, njll.;iphasi eliphezulu
Idivayisi yokuhlunga ifinyelela ikakhulukazi inhloso yokuhlunga ama-harmonics we-oda eliphezulu we-13 nangaphezulu.Idivayisi ye-TAL ifakwe idivayisi yokulawula ukushintsha okuzenzakalelayo kanye nokuvikelwa kwekhompyutha encane
idivayisi.
umgomo wokusebenza:
Idivayisi yokuhlunga ye-TAL yakhiwe ikakhulukazi ama-capacitor okuhlunga, ama-reactors okuhlunga, njll. ukuze kwakhe izihlungi ze-LC.
isinxephezelo somsebenzi.Amadivayisi okuhlunga e-LC ikakhulukazi ahlanganisa amadivayisi okuhlunga ashunwe kanye, izisetshenziswa zokuhlunga ezishunwe kabili, izihlungi ezisezingeni eliphezulu, namadivayisi okuhlunga ohlobo lwe-C.Ekusetshenzisweni okungokoqobo, amaqembu amaningana wamadivayisi okuhlunga aklanywa ngokuya ngokusatshalaliswa nosayizi wesidingo samandla asebenzayo esivumelanayo.
Ukusetha le harmonic kulingana nesiteshi se-impedance ephansi, ukuze iningi lamanje le-harmonic ligeleze kumjikelezo wesihlungi.Isihlungi sokudlula okuphezulu sisho imvamisa yokunqamuka
Ama-harmonic angenhla wonke abonisa ukuncibilika okuphansi, futhi idivayisi yokuhlunga yohlobo lwe-C inezici zokushuna kwebhendi ebanzi nokulahlekelwa okuphansi.Ukuqoqwa kwemishini yokuhlunga kumele kwenziwe
Ukubala okunembile, hhayi nje ukuhlunga i-harmonic yamanje eyinhloko, kodwa futhi ukuhlangabezana nezidingo zesinxephezelo samandla asebenzayo, kodwa futhi ukuvimbela imvamisa ethile ephelele.
I-harmonic current ikhuliswa ngenxa ye-parallel resonance yedivayisi yokuhlunga kanye ne-impedance yesistimu.Isofthiwe yenkampani yethu yokuklama idivayisi yokuhlunga ingasekelwe
Izici ezithile zomsebenzisi ngamunye zinganikeza ngokushesha nangokunengqondo isikimu sedizayini yesihlungi esinembile ngemodeli yokulingisa enembile.
