Intermediate zaus induction rauv
Lub tshuab hluav taws xob nruab nrab siv hluav taws xob nruab nrab siv hluav taws xob rau induction cua sov, melting thiab kev txuag hluav taws xob.Lub tshuab hluav taws xob nruab nrab feem ntau yog siv rau smelting carbon steel, alloy steel, hom hlau, tab sis kuj tuaj yeem siv rau tooj liab, txhuas thiab lwm yam tsis-ferrous hlau smelting thiab kub raising.Me me, lub teeb yuag, siab npaum, tsawg zog noj. , ceev melting, yooj yim los tswj lub cub tawg kub, siab productivity.Intermediate zaus rauv feem ntau yog siv nyob rau hauv Hoobkas casting thiab kev kho cua sov.Lub tshuab hluav taws xob nruab nrab tau maj mam hloov cov hluav taws xob hluav taws xob hluav taws xob, hluav taws xob hluav taws xob, roj cub hluav taws xob thiab lub tshuab hluav taws xob zoo tib yam, thiab tau dhau los ua ib qho kev nyiam tshiab hauv Hoobkas casting thiab kev kho cua sov.Ib qho, nruab nrab zaus rauv ua hauj lwm hauv paus ntsiab lusIntermediate zaus furnace los ntawm silicon tswj rectifier inverter los tsim nruab nrab. zaus lub hwj chim, xa mus rau lub cub tawg lub cev coil, rauv (coil) nyob rau hauv nruab nrab ntawm lub nruab nrab zaus electromagnetic teb, thiaj li hais tias cov hlau nyob rau hauv lub cub tawg lub cev tsim eddy tam sim no, eddy tam sim no thiab ces ua rau cov hlau tsim ib tug loj npaum li cas ntawm tshav kub. Cov hlau melting.Intermediate zaus rauv yog tsim los ntawm cov khoom siv hluav taws xob, lub nplhaib induction thiab crucible ua los ntawm cov khoom siv refractory nyob rau hauv induction nplhaib.In lub crucible uas muaj hlau rauv nqi, sib npaug rau txhua winding transformer, induction coil, thaum nyob rau hauv ac zog, tsim alternating magnetic teb nyob rau hauv induction kauj, lub magnetic quab yuam kab nyob rau hauv lub crucible cub tawg nqi, hlau yog tsim nyob rau hauv lub cub tawg nqi induction electromotive quab yuam, vim lub nra nws tus kheej tsim ib lub voj kaw, qhov taw tes ntawm no vice winding tsuas yog tig thiab yog. kaw.Yog li ntawd, inductive tam sim no yog generated ib txhij nyob rau hauv tus nqi.Thaum lub induced tam sim no dhau los ntawm tus nqi, tus nqi yog rhuab kom nws yaj.Cov txheej txheem ua hauj lwm ntawm qhov nruab nrab zaus rauv kuj yog ib hom induction cooker, raws li nram no: ua ntej, los ntawm ib tug inverter fais fab mov, peb-theem alternating. tam sim no rectifier (SCR) mus rau hauv ib theem dc, ces los ntawm inverter choj inverter rau hauv ib hom alternating tam sim no (ac), 500-1000 Hz zaus mem tes los ntawm tooj liab nplhaib tsim nyob rau hauv lub cub tawg magnetic teb, ua lub voj voog hlau ua eddy tam sim no. Sib nqus teb, eddy tam sim no ntws los ntawm cov hlau rhuab, tsim kom sov, thiaj li ua tiav lub hom phiaj ntawm smelting steel.Qhov feem ntau zaus ntawm nruab nrab zaus hluav taws xob rauv yog 800-20000Hz.Ob, nruab nrab zaus rauv ua hauj lwm hauv paus ntsiab lus daim duab lub ntsiab Circuit Court thaiv daim duab ntawm Lub tshuab yog pom nyob rau hauv daim duab.The rectifier txais peb-theem choj tswj rectifier Circuit Court, lub inverter txais ib-theem choj inverter Circuit Court, lub load yog parallel resonant daim ntawv, DC filtering txuas yog loj inductance filtering, thiaj li ua tau raws li cov input kev xav tau ntawm parallel inverters.
AC-DC-AC converter
Peb theem choj tswj rectifier Circuit Court
Cov zis voltage ntawm peb-theem choj tswj rectifier Circuit Court yog: Ud = 2.34 U2cosa…(1) Ud yog tus nqi nruab nrab ntawm cov zis DC voltageU2 — Grid theem voltageA — Trigger theem hloov AngleThe waveform ntawm cov zis voltage ntawm txawv A ces kaum (nyob rau hauv inductive load thiab non-intermittent tam sim no). Lub a> Lub xeev ntawm 90 ° yog hu ua lub inverting ua hauj lwm lub xeev ntawm rectification, nws essence yog hais tias lub load pub rov qab zog rau lub hwj chim kab.
