Ulwazi oluyisisekelo lwabasebenzisi
Inkampani yokukhipha ama-valve esangweni ikakhulukazi ikhiqiza imikhiqizo yama-valve.Imishini yokukhiqiza yenkampani ihlanganisa isethi yesithando somlilo esingamathani ama-2-frequency medium-frequency induction, enikwa amandla uhlelo lokuphakela amandla kagesi olungu-2000 kVA (10KV/0.75 kVA).Ifakwe amakhabethe esinxephezelo angu-2 anomthamo ongu-600 kVA, isithando somlilo esiyithani elingu-1 le-intermediate intermediate induction, ama-800 kVA (10KV/0.4KV) ama-transformer obuchwepheshe kanye nabasebenzi, kanye nekhabethe lesinxephezelo somthamo wevolumu engu-300 kVA .Umdwebo wesistimu yokunikezwa kwamandla umi kanje:
Idatha yangempela yokusebenza
Amandla asobala wesithando somlilo esiphakathi nendawo esifakwe isiguquli esingu-2000KVA singama-700KVA-2100KVA, amandla asebenzayo angu-P=280KW-1930KW, umthwalo osebenzayo ngu-Q=687KAR-830KAR, isici samandla yi-PF=0.4-0.92, yamanje esebenzayoⅰ = 538 A-1660 A, amandla abonakalayo wesithando somlilo esiphakathi nendawo esifakwe isiguquli esingu-800KVA singama-200KVA-836KVA.Amandla asebenzayo ngu-P=60KW-750KW, umthwalo osebenzayo ngu-Q=190KAR-360KAR, isici samandla ngu-PF=0.3-0.9, kanye namandla asebenzayo angu-i=288 A-1200 A. Ngoba ikhabhinethi yesinxephezelo se-capacitor ayikwazi ukubekwa ukusebenza (isinxephezelo esizenzakalelayo sihluleka, lapho i-capacitor isetshenziswa ngesandla, umsindo we-capacitor awujwayelekile, i-circuit breaker ihamba, i-capacitor ihlanganisiwe, uwoyela uvuzile, uqhekekile, futhi awukwazi ukusetshenziswa), amandla aphelele wenyanga. PF=0.78, futhi izinga lenzalo yemali ebolekiwe yanyanga zonke lilungiswa libe ngaphezu kuka-32,000 yuan.
Ukuhlaziywa Kwesimo Sesistimu Yamandla
Umthwalo oyinhloko we-intermediate frequency electric furnace rectifier amandla kagesi ukulungiswa kwe-6-pulse.Imishini yokulungisa iguqula i-AC ibe yi-DC kuyilapho ikhiqiza inani elikhulu lama-harmonics.Umthombo ovamile we-harmonic wamanje we-harmonic ujovwa kugridi, futhi ukuvinjelwa kwegridi kukhiqiza amandla kagesi e-harmonic, okubangela amandla kagesi wegridi Ukuhlanekezela kwamanje kuthinta ikhwalithi yokunikezwa kwamandla kanye nokuphepha kokusebenza, kwandisa ukulahlekelwa kolayini kanye nokunciphisa amandla kagesi, futhi kwandisa amandla.Lapho ibhange le-capacitor yesinxephezelo samandla asebenzayo liqala ukusebenza, ngenxa yokuthi isici se-harmonic i-impedance ye-capacitor bank incane, ama-harmonics amaningi angeniswa ebhange le-capacitor, kanye nenani le-capacitive current Ukwanda okusheshayo kuthinta kakhulu impilo yayo yesevisi.Ngakolunye uhlangothi, lapho i-harmonic capacitive reactance yebhange le-capacitor ilingana ne-harmonic inductive reactance yohlelo kanye ne-resonance ewuchungechunge, i-harmonic current ikhuliswa kakhulu (izikhathi ezingu-2-10), okuholela ekushiseni kanye nokulimala i-capacitor.Ngaphezu kwalokho, ama-harmonics azobangela ukuthi igagasi le-DC sinusoidal lishintshe, okuholela kugagasi eliphakeme le-sawtooth, okulula ukubangela ukukhishwa okuyingxenye ku-insulating material.Ukukhishwa kwengxenye yesikhathi eside kuzophinde kusheshise ukuguga kwezinto zokuvikela futhi kubangele kalula ukulimala kwe-capacitor.Ngakho-ke, ikhabhinethi yesinxephezelo samandla asebenzayo we-capacitor ayikwazi ukusetshenziselwa isinxephezelo sesithando somlilo esiphakathi nendawo, futhi idivayisi yesinxephezelo samandla asebenzayo esihlungi enomsebenzi wokucindezela wamanje we-pulse kufanele ikhethwe.
Uhlelo lokwelapha isinxephezelo samandla asebenzayo
Imigomo yokubusa
Idizayini yempahla yesinxephezelo yesihlungi ihlangabezana nezidingo zokucindezelwa kwe-harmonic kanye nokuphathwa kokucindezelwa kwamandla okusebenzayo.
Ngaphansi kwemodi yokusebenza yezinhlelo ze-0.75KV kanye ne-0.4KV, ngemva kokuba okokusebenza kwesinxephezelo kwesihlungi kusetshenziswe, i-pulse current iyacindezelwa, futhi isilinganiso samandla sanyanga zonke sidlula u-0.95.Okokufaka kweluphu yesinxephezelo sesihlungi ngeke kubangele i-pulse current resonance noma i-resonance overvoltage kanye ne-overcurrent.

Design imibono
Ngokwesimo esithile senkampani, inkampani yethu idizayine isethi yesikimu sesinxephezelo sesinxephezelo samandla amaphakathi aphakathi nendawo esishisayo.Cabangela ngokugcwele isici samandla omthwalo kanye nokucindezelwa kwe-harmonic, bese ufaka isethi yezihlungi zesinxephezelo samandla asebenzayo ane-voltage ephansi ohlangothini olungezansi lwe-voltage yenkampani engu-0.75KV kanye neziguquli ze-0.4KV ukuze ucindezele ama-harmonics, unxephezele amandla asebenzayo, futhi uthuthukise isici samandla.Ngesikhathi sokusebenza kwesithando somlilo esiphakathi nendawo, idivayisi yokulungisa ikhiqiza ama-harmonic angu-6K+1, futhi uchungechunge lwe-Fourier lusetshenziselwa ukubola nokuguqula okwamanje ukuze kukhiqizwe ama-harmonic angu-5 we-250HZ kanye nama-harmonics angu-7 ngaphezu kuka-350HZ.Ngakho-ke, lapho uklama isinxephezelo esingasebenzi sesihlungi sesithando somlilo, kufanele kuqinisekiswe ukuthi isifunda segatsha lesinxephezelo sesihlungi sinxephezela amandla angasebenzi ngokucindezela ngokuphumelelayo ukuhambisana kwamafrikhwensi angaphezu kuka-250HZ no-350HZ, futhi kwandisa isici samandla.
umsebenzi wokuklama
Isici samandla esibanzi se-2-ton intermediate frequency induction induction factor ehambisana nesiguquli esingu-2000 kVA sinxeshezelwa ukusuka ku-0.78 kuya cishe ku-0.95.Idivayisi yesinxephezelo yesihlungi idinga ukuhlonyiswa ngomthamo ongu-820 kVA, futhi iguqule ngokuzenzakalelayo ibe ngamaqembu angu-6 amakhono, ngalinye elifana nokujikajika ohlangothini olungezansi lwamandla kagesi we-transformer ukuze bathole isinxephezelo.Umthamo wokulungisa ukuhlukaniswa kwebanga ngu-60KVAR, ongahlangabezana nezidingo ezihlukahlukene zamandla zesithando somlilo esiphakathi nendawo.Isici samandla esibanzi sethani elingu-1 lesithando somlilo esimaphakathi esifaniswa nesiguquli esingu-800 kVA sinxeshezelwa sisuka ku-0.78 siye cishe ku-0.95.Impahla yesinxephezelo yesihlungi idinga ukuhlonyiswa ngomthamo ongu-360 kVA, engaguqulwa ngokuzenzakalela ibe ngamaqembu angu-6 omthamo, futhi umthamo wokulungisa ohleliwe ungu-50 kVA, ongahlangabezana nezidingo ezihlukahlukene zamandla zesithando somlilo esiphakathi nendawo.Lolu hlobo lomklamo luqinisekisa ngokugcwele ukuthi isici samandla esilungisiwe siphezulu kuno-0.95.
Ukuhlaziywa komthelela ngemva kokufakwa kwesinxephezelo sesihlungi
Ekuqaleni kukaJuni 2010, idivayisi yesinxephezelo samandla esinxephezelo sesithando somlilo esimaphakathi esimaphakathi safakwa futhi saqala ukusebenza.Isisetshenziswa silandelela ngokuzenzakalelayo ushintsho lomthwalo wesithando somlilo esimaphakathi esimaphakathi, sinxephezela ngokukhethekile umthwalo osebenzayo, futhi sithuthukisa isici samandla.imininingwane kanjena:
