Ngwa eletrọnịkị ike nke ikpo oku ọkụ

A na-eji kpo oku induction eme ihe maka mgbaze igwe, ichekwa ọkụ, ịgbado ọkụ, ịgbado ọkụ, ọkụ, diathermy, ịdị ọcha ọla mmiri, ọgwụgwọ okpomọkụ, ịgbado ọkpọkọ, na uto kristal.Ngwunye ọkụ induction gụnyere sekit rectifier, sekit inverter, sekit ibu, njikwa na sekit nchebe.

Nkà na ụzụ na-enye ọkụ eletrik maka ikpo ọkụ induction bụ nkà na ụzụ na-emezigharị ike ugboro ugboro (50Hz) iji duzie ike wee gbanwee na ugboro ugboro (400Hz ~ 200kHz) site na ngwaọrụ semiconductor dị ka thyristor, MOSFET ma ọ bụ IGBT.Njirimara teknụzụ na ụzọ njikwa mgbanwe, ike nrụpụta dị ukwuu, yana arụmọrụ dị elu karịa otu, yana adaba iji gbanwee ugboro dịka achọrọ kpo oku.

Onye na-emezigharị nke obere na ọkara akụrụngwa na-enye ike na-emezigharị thyristor atọ.Maka akụrụngwa na-enye ike dị elu, a ga-etinye 12-pulse thyristor rectification iji meziwanye ọkwa ike nke ike ma belata grid-side harmonic current.The inverter ike unit na-emi esịnede elu-voltaji elu-ugbu a ngwa ngwa mgba ọkụ thyristor yiri wee usoro ejikọrọ na-aghọta na elu ike mmepụta.

Enwere ike kewaa sekit inverter na resonant ụzọ abụọ dị ka ihe nrụpụta: 1) ụdị resonant yiri ya, 2) ụdị resonant usoro.

Parallel resonant ụdị: elu-voltage elu-ugbu a mmiri jụrụ thyristor (SCR) na-eji na-etolite a ugbu a ụdị inverter ike unit, na elu ike mmepụta na-ghọtara site superposition nke thyristors.The resonant sekit n'ozuzu na-eji a zuru oke yiri resonance Ọdịdị, na-ahọrọ abụọ-voltaji ma ọ bụ transformer mode dịkwuo voltaji na inductor dị ka dị iche iche chọrọ, tumadi etinyere na kpo oku ọgwụgwọ usoro.

Series resonant ụdị: elu-voltage elu-ugbu a mmiri jụrụ thyristor (SCR) na ngwa ngwa diode na-eji na-etolite a voltaji-ụdị inverter ike unit, na elu ike mmepụta na-ghọtara site superposition nke thyristors.The resonance sekit na-eji usoro resonance Ọdịdị, na transformer na-nakweere ka dakọtara ibu chọrọ.Na mgbakwunye na uru nke ihe ike dị elu na Grid-n'akụkụ, oke mgbanwe ike dị ukwuu, arụmọrụ kpo oku dị elu na ọnụ ọgụgụ mmalite mmalite dị elu, ọ na-aghọwanyewanye nke a na-ejikarị n'ime afọ ugbu a ma tinye ya n'ọrụ na usoro agbaze.

Mgbe emeziwanye usoro nrụpụta, Runau rụpụtara thyristor ngwa ngwa na-eji radieshon neutron na usoro ndị ọzọ na-ebelata oge nkwụsị na ikike ike na-abawanye n'ihi ya.

Ọkụ ọkụ induction kpo oku na-anabata thyristor dị ka isi ngwaọrụ kpuchiri mpaghara niile na ugboro ole na-arụ ọrụ n'okpuru 8kHz.The mmepụta ike ike na-ekewa n'ime 50, 160, 250, 500, 1000, 2000, 2500, 3000kW, 5000KW, 10000KW ọrụ ugboro bụ 200Hz, 400Hz , 1kHz, 2.5kHz, 8kHz, 8kHz.10 tọn, tọn 12, tọn 20 maka agbaze ígwè na ndoputa thermal, akụrụngwa ike bụ isi bụ ọkụ ọkụ ugboro ugboro.Ugbu a ikike mmepụta kachasị na-abịa na 20000KW nke 40Ton.Na thyristor bụ isi ike ntụgharị & ngbanwe akụrụngwa a ga-etinye.
