Load daim ntawv thov dav siv nyob rau hauv smelting thiab cua sov ntawm non-ferrous thiab ferrous hlau.Xws li cam khwb cia hlau hauv smelters, dav hlau, stainless hlau phaj, hlau alloy, tooj liab, txhuas, kub, nyiaj thiab txhuas alloy, thiab lwm yam.;Hlau thiab tooj liab qhov chaw rau diathermy forging, aluminium ingots rau extrusion molding, thiab lwm yam. Ua kom quenching thiab tempering kev kho mob xws li kev kho cua sov thiab kev kho cua sov ntawm cov ntaub ntawv hlau.Cov khoom siv hluav taws xob nruab nrab ntawm lub tshuab cua sov yog qhov me me, lub teeb hauv qhov hnyav, kev ua haujlwm siab, zoo heev hauv thermal ua haujlwm zoo, thiab zoo rau ib puag ncig.Nws yog lub cim tom ntej ntawm cov khoom siv cua sov hlau rau kev tshem tawm cov hluav taws xob hluav taws xob sai sai, cov hluav taws xob hluav taws xob, cov roj hluav taws xob, thiab cov cua sov zoo tib yam.
Load harmonic yam ntxwv;intermediate zaus melting furnaces yog ntau thiab ntau lug siv nyob rau hauv smelting, casting thiab lwm yam lag luam.Txawm li cas los xij, thaum ua haujlwm, qhov nruab nrab zaus hluav taws xob qhov cub siv hluav taws xob hloov kho thiab inverter thev naus laus zis, ua rau muaj coob tus tam sim no thiab voltage harmonics.Harmonic kuab paug rau lub zog muab hluav taws xob ua rau cov cuab yeej precision ua haujlwm nyob rau hauv cov txheej txheem ntawm kev ua yuam kev thiab ua rau kom poob ntawm cov khoom siv hluav taws xob.Cov hluav taws xob hluav taws xob ntawm qhov nruab nrab zaus induction rauv yog cov mem tes loj tam sim no hauv cov khoom siv hluav taws xob, thiab feem ntau hloov cov khoom siv hluav taws xob rau nruab nrab zaus induction furnaces thiab high zaus induction furnaces.Feem ntau, 6 ib leeg-pulse intermediate zaus induction furnaces feem ntau tsim cov yam ntxwv sib haum xeeb ntawm 5, 7, 11, thiab 13 zaug.Rau 12 ib leeg-pulse converter nruab nrab zaus induction furnaces, cov harmonics tseem ceeb yog 11th, 13th, 23rd thiab 25th yam ntxwv harmonics.Feem ntau hais lus, 6 pulses yog siv rau cov khoom siv me me, 12 pulses yog siv rau cov khoom siv loj loj, xws li Y / △ / Y hom rauv transformer, lossis 2 lub tshuab hluav taws xob hloov hluav taws xob yog siv rau cov khoom siv hluav taws xob.
Raws li cov teeb meem tshwm sim hauv kev ua ub ua no, qhov sib haum xeeb ntawm cov dej hauv nruab nrab ntawm lub tshuab hluav taws xob nruab nrab yog tsawg dua 85%, tab sis cov khoom siv kho tshuab feem ntau yog tswj hwm los ntawm kev sib haum xeeb, kev txhim kho ntawm kev sib haum xeeb tuaj yeem tsis quav ntsej, thiab kev txuag hluav taws xob yog tsis txaus siab.Dab tsi yog qhov hnyav dua yog tias lub zog sib haum xeeb nyob deb tshaj qhov tso cai ntawm cov khoom siv hluav taws xob txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, thiab nws yooj yim rau kev puas tsuaj tom qab siv mus ntev, thiab kev sib tsoo tshwm sim ntau zaus.Yog li ntawd, nyob rau hauv kev teb rau qhov kev xav tau sai ntawm ntau cov khoom kawg, kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob ntawm nruab nrab zaus furnaces tau dhau los ua teeb meem mus sij hawm ntev hauv kev lag luam ntawm kev siv hluav taws xob, uas cuam tshuam ntau yam kev lag luam thiab kev lag luam.
1. Lub tshuab hluav taws xob nruab nrab ntawm lub tshuab hluav taws xob ua kom muaj ntau qhov sib haum xeeb thaum siv, thiab kev sib haum xeeb hauv daim phiaj hluav taws xob ua rau muaj teeb meem loj.
2. Harmonics yuav txo qhov kev ua tau zoo ntawm kev xa hluav taws xob thiab kev siv hluav taws xob, cov khoom siv hluav taws xob overheat, tsim kev co thiab suab nrov, tsis zoo rwb thaiv tsev, txo lub neej, thiab txawm tias malfunction thiab hlawv tawm.
3. Harmonics yuav ua rau lub zos nyob rau hauv parallel resonance thiab series resonance ntawm lub hwj chim system,
4. Amplify lub harmonic cov ntsiab lus, hlawv tawm cov capacitance them nyiaj thiab lwm yam khoom siv;
5. Harmonics ua rau kev tiv thaiv relay thiab tsis siv neeg lub tshuab ua haujlwm tsis zoo;
5. Sab nraum lub zog hluav taws xob, kev sib haum xeeb cuam tshuam nrog cov khoom siv sib txuas lus thiab cov khoom siv hluav taws xob.
6. Yog tias lub hwj chim tsis ua raws li cov cai ntawm 0.90 ntawm lub chaw ua haujlwm fais fab, qhov kev nplua rau kev kho cov nqi hluav taws xob yuav raug nplua.
7. Lub zog qis ntawm qhov nruab nrab zaus induction rauv thiab qhov loj ntawm reactive load muab los ntawm qhov tshwj xeeb transformer nce lub nra ntawm lub transformer.
8. Kuj tseem muaj qhov xwm txheej: lub hwj chim ntawm qee cov neeg siv khoom nruab nrab zaus induction rauv tsis qis thaum lawv muab tso rau hauv kev ua haujlwm, thiab lawv tsuas yog yuav tsum tswj cov mem tes tam sim no.
Yog li ntawd, kev txhim kho lub zog zoo ntawm qhov nruab nrab zaus qhov cub tau dhau los ua tus yuam sij rau cov lus teb.Cov kev daws teeb meem xaiv los ntawm:
npaj 1
Centralized tswj (nruab cov lim dej sib haum xeeb hauv chav faib hluav taws xob tsim nyog rau kev ua haujlwm ib txhij ntawm ntau lub tshuab hluav taws xob nruab nrab zaus)
1. Siv cov ceg tswj kev sib haum xeeb (5, 7, 11 lim) + reactive zog tswj ceg.Tom qab cov cuab yeej lim dej tau muab tso rau hauv kev ua haujlwm, kev tswj hwm kev sib haum xeeb thiab kev siv hluav taws xob rov ua haujlwm ntawm cov khoom siv hluav taws xob ua tau raws li qhov yuav tsum tau ua.
2. Txais cov lim dej ua haujlwm (tshem tawm qhov kev txiav txim ntawm dynamic harmonics) thiab harmonic countermeasure ceg Circuit Court (5, 7, 11 txiav txim lim) # + invalid adjustment ceg Circuit Court, thiab tom qab muab rau lub lim cov khoom them nyiaj, muab tso rau pem hauv ntej Thov rau invalid nyiaj ntawm lub zog mov system.
Scenario 2
Kev tswj hwm ntawm qhov chaw (teeb tsa rau ntawm qhov chaw siab tshaj plaws kev sib haum xeeb lim dej ntawm ib sab ntawm lub zog vaj huam sib luag ntawm qhov nruab nrab zaus qhov cub)
1. Txais kev tiv thaiv kev sib haum xeeb bypass (5th, 7th, 11th lim), cia li taug qab kev ua haujlwm ntawm lub tshuab hluav taws xob nruab nrab, daws cov kev sib haum xeeb ntawm qhov chaw, thiab tsis cuam tshuam rau kev ua haujlwm ntawm lwm cov khoom siv thaum lub sij hawm tsim khoom, thiab cov harmonics tsis ncav cuag. tus qauv tom qab muab tso rau hauv kev siv.
2. Txais siv cov lim dej (bandwidth adjustment unit) thiab lim bypass circuit (5th, 7th filter), high-order harmonics tom qab switching on do not reach the benchmark.
Kev xaiv 3:
Nta peb cov kev tswj hwm rov ua dua siab dua lub zog ua haujlwm lub zog lim.Peb lub zog Hongyan APF stand-alone muaj 100A, 200A, 300A, 500A thiab lwm yam specifications, thiab 6 units tuaj yeem ua ke.Kov kev koom tes ntawm txhua tus khub zaus.
