Ulwazi oluyisisekelo lwabasebenzisi
Inkampani yokukhipha ama-valve esangweni ikakhulukazi ikhiqiza imikhiqizo yama-valve.Imishini yokukhiqiza yenkampani ihlanganisa isithando somlilo sethani elilodwa le-medium-frequency induction, esebenzisa i-2000 kVA (10KV/0.75 kVA) uhlelo lobuchwepheshe lokunikezela ngogesi we-transformer professional, futhi lufakwe amakhabethe amabili esinxephezelo se-capacitor anomthamo ongu-600 kVA, a isithando somlilo sethani elilodwa le-medium-frequency induction, 800 kVA (10KV/0.4 kVA) uhlelo lokunikezela kwamandla kagesi ochwepheshile we-transformer, ikhabethe lesinxephezelo se-capacitor enomthamo ongu-300 kVA.Umdwebo wesistimu yokunikezwa kwamandla umi kanje:
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 wokunikezwa kwamandla okulungisiwe esithandweni sokungenisa imvamisa emaphakathi ama-ballast single pulse ballast.Imishini yokulungisa ikhiqiza ama-harmonics amaningi lapho iguqula i-AC yamanje ibe yi-DC, okuwumthombo ojwayelekile wama-harmonics.I-harmonic current eyethulwa kugridi yamandla izodala i-harmonic yokusebenza i-voltage ekuvimbeleni okuyisici kwegridi yamandla, okuholela ekulahlekeni kohlaka lwe-voltage esebenzayo kanye namandla egridi yamandla, kubeke engcupheni ikhwalithi nokusebenza kokuphepha kohlelo lokuphakelwa kukagesi, kukhuphuke. ukulahleka kolayini kanye nokuchezukiswa kwamandla kagesi okusebenza, nokudangala umonakalo kugridi yamandla nokucubungula Impahla kagesi yefekthri izodala izingozi ezimbi.Lapho ibhange le-capacitor yesinxephezelo samandla asebenzayo liqala ukusebenza, ngenxa yokuthi isici se-harmonic i-impedance ye-capacitor bank incane, inani elikhulu lama-harmonics lingeniswa ebhange le-capacitor, futhi amandla amanje akhula ngokushesha, okuthinta 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
Amadivayisi esinxephezelo esihlungi adizayinelwe ukuhlangabezana nezimfuneko zokulawula zokucindezelwa kwama-harmonics namandla asebenzayo.
Kumodi yokusebenza yezinhlelo ze-0.75KV kanye ne-0.4KV, ngemuva kokuthi okokusebenza kwesinxephezelo sesihlungi kushiye imboni, ama-harmonics we-oda eliphezulu acindezelwa ngesilinganiso samandla sanyanga zonke esingu-0.95 noma ngaphezulu.
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, ekwakhiweni kwesinxephezelo samandla asebenzayo wesihlungi sokungeniswa kwesithando somlilo, imvamisa engu-250HZ, 350HZ nendawo ezungezile kufanele yakhelwe ukuqinisekisa ukuthi iluphu yesinxephezelo sesihlungi ingacindezela ngokunengqondo ukushaya kwenhliziyo kuyilapho inxephezela umthwalo osebenzayo futhi ithuthukisa 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:
Ngemva kokuvulwa kwedivayisi yesinxephezelo sesihlungi, ijika lokushintsha isici samandla licishe libe ngu-0.97 (isici samandla lapho idivayisi yesinxephezelo sesihlungi sinqanyulwa cishe ngu-0.8)
Layisha ukusebenza
I-current ye-2000KVA transformer incishisiwe isuka ku-1530A iye ku-1210A, ukwehla kwe-21%;i-current ye-800KVA transformer incishisiwe isuka ku-1140A iye ku-920A, ukwehla kwe-19.3%, okulingana nokunciphisa i-20% ye-transformer, okungukuthi, i-560KVA, futhi umonakalo wamandla okukhipha ngemva kwesinxephezelo uyancipha ngo-21%.;Umonakalo wesiguquli wehliswe nge-WT=?Pd1S2) 2**[1-(1-1/cos2)2]=24{(0.78?2800)/280}20.415(kwh).Ukulahleka kwe-transformer ngama-yuan angama-24, futhi ukulahleka kwanyanga zonke kungu-15KW=150d;izindleko zokulondoloza zanyanga zonke ngu-1580d=230d*30d(2307){0.782800}20d.
isimo amandla factor
Kule nyanga, isici samandla esiphelele senkampani sikhuphuke sisuka ku-0.78 saya ku-0.97, inani elisebenzayo lanyanga zonke kanye nezikweletu zezinsiza zalungiswa zaba ngu-0, futhi inhlawulo yashintshwa yaba ngu-4,680 yuan.Kusukela lapho, isici samandla sanyanga zonke siye sahlala ku-0.97-0.98, futhi umvuzo wenyanga ubuphakathi kuka-3,000-5,000 yuan.
Ngokuvamile, lo mkhiqizo unekhono elihle kakhulu lokucindezela i-pulse yamanje kanye nokunxephezela amandla asebenzayo, ukuxazulula inkinga yenkampani yesikhathi eside yokuthela inzalo nezinhlawulo zezindleko zesevisi, ukuthuthukisa umthamo wokukhipha ama-transformers, futhi ulethe izinzuzo ezisobala zezomnotho enkampanini , Itholiwe. utshalomali lwekhasimende esikhathini esingaphansi konyaka.Ngakho-ke, isinxephezelo samandla asebenzayo sesithando somlilo esiphakathi esikhiqizwa yinkampani siyanelisa kakhulu, futhi sizoheha amakhasimende amaningi esikhathini esizayo.
