Cov yam ntxwv tseem ceeb ntawm submerged arc rauv transformers
Nruam, ruaj khov, thiab siab load tus nqi:
Cov txheej txheem smelting yog uninterrupted 24 teev ib hnub twg. Lub transformer ua haujlwm ntawm lossis ze rau qhov ntsuas load rau lub sijhawm ntev, nrhiav kev ua haujlwm siab heev thiab kev ntseeg tau. Qhov no txawv kiag li los ntawm lub sij hawm cuam tshuam load ntawm arc furnaces.
Tsis tshua muaj hluav taws xob tsawg theem nrab thiab tsis tshua muaj siab theem nrab tam sim no:
Txhawm rau kom mloog zoo rau lub zog hauv qhov cub hluav taws xob thiab tsis txhob poob hluav taws xob thiab kev puas tsuaj rau lub qhov cub hauv ob sab phlu uas tshwm sim los ntawm cov arcs ntev heev, submerged arc furnaces txais yuav "submerged arc" lossis "subsurface arc" ua haujlwm. Qhov no yuav tsum muaj qhov tsawg kawg nkaus kev khiav hauj lwm voltage (feem ntau kaum mus rau pua pua ntawm volts), uas ua rau ib tug xav tsis thoob tam sim no theem nrab (txog kaum tawm txhiab mus rau ntau tshaj 100,000 amperes).
Tshwj xeeb impedance yuav tsum:
Txaus impedance yog xav tau los txwv luv luv -circuit tam sim no, txawm hais tias tsis yog mus rau theem siab mus rau refining furnace transformers. Tus nqi impedance (feem ntau yog nruab nrab ntawm 6% thiab 12%) yuav tsum phim cov nqi them rau kev pom lub zog tawm tswv yim.
Qhov tseem ceeb ntawm peb -phase tshuav nyiaj li cas:
Qhov sib npaug ntawm qhov tam sim no thiab kev ua haujlwm ntawm peb -theem electrodes yog ncaj qha ntsig txog kev ruaj ntseg ntawm cov khoom siv hluav taws xob, cov khoom zoo, thiab kev siv hluav taws xob. Tus tsim ntawm transformer thiab luv network system yuav tsum xyuas kom meej peb -theem sib npaug ntau npaum li sai tau.
Txhim kho qhov tseem ceeb ntawm cov nthwv dej loj loj ntawm daim phiaj hluav taws xob:
Submerged arc furnaces yog "cov neeg siv hluav taws xob loj" ntawm daim phiaj hluav taws xob, uas feem ntau tsis tshua muaj hluav taws xob (natural power factor yog li 0.65-0.8), thiab yuav tsum tau nruab nrog cov khoom siv hluav taws xob loj loj.
Daim ntawv thov thiab xaiv cov ntsiab lus
Txheej txheem ua ntej:
Transformer tsis (tshwj xeeb tshaj yog qhov nruab nrab voltage ntau) yuav tsum nruj me ntsis sib phim thiab suav nrog cov txheej txheem tsis xws li hom rauv, khoom ntau yam, cov yam ntxwv ntawm cov khoom siv raw, thiab cov kab hluav taws xob electrode.
Lub "luv network" yog qhov txuas ntxiv ntawm qhov system:
Lub impedance thiab qhov sib npaug ntawm ntu los ntawm qhov hluav taws xob thib ob kawg ntawm lub tshuab hluav taws xob mus rau lub tshuab hluav taws xob (hu ua "luv network") muaj kev cuam tshuam rau lub qhov cub hluav taws xob uas yuav luag yog qhov tseem ceeb ntawm lub transformer nws tus kheej. Lub transformer thiab lub network luv luv (tooj tooj liab, dej-txias cables, conductive puab tsaig, thiab lwm yam) yuav tsum tau tsim los ua ib qho kev sib txuas hluav taws xob.
Reactive zog them nyiaj thiab harmonic tswj:
Loj -scale dynamic reactive zog them nyiaj thiab lim cov cuab yeej xws li TCR/TSC hom SVC los yog FC yuav tsum tau nruab los txhim kho lub hwj chim, stabilize daim phiaj voltage, thiab nqus harmonics.
Kev ntseeg siab ntawm lub tshuab cua txias:
Txhua qhov kev cuam tshuam cua txias tuaj yeem ua rau muaj kev puas tsuaj loj hauv ib lossis ob feeb.
Kev tswj kom zoo:
Cov txheej txheem tsim khoom, kev kho rwb thaiv tsev, thiab cov qauv hluav taws xob ntawm siab - windings tam sim no yog cov yuam sij rau kev ua haujlwm zoo thiab kev pabcuam lub neej.
Peb muaj kev paub dhau los hauv kev tsim submerged arc rauv transformers. Hauv kev teb rau cov kev xav tau ntawm kev sib txuas ua ke tag nrho, rau cov khoom siv hluav taws xob nrog lub peev xwm ntawm 15,000 kVA thiab siab dua, peb tsim lawv ua ib zaug -theem transformers nrog cov qauv uas muaj dej-cooled tube (adjustable copper tube) sab qhov hluav taws xob, ntawm -load voltage regulating, thiab unified voltage regulating. Rau qhov loj - nplai ntawm -load voltage regulation thiab 110kV class khoom, peb txais yuav "8"-zoo li tus coils uas yog tag nrho cov qhov txhab thiab tsim nyob rau hauv ib tug mus, uas txhim khu lub zog coil thiab txo eddy tam sim no poob. Rau transformer roj tso tsheb hlau luam, peb ua qhov tseem ceeb ntawm kev siv cov tais tais tais, txo cov vuam seams kom ntau li ntau tau, thiab nruj me ntsis ua qhov zoo thiab qhov tsis zoo ntawm kev ntsuas siab kom ntseeg tau tias cov khoom sealing.
