Inverter intermediate frequency furnaces must have advantages over parallel intermediate frequency furnaces

1. The thyristor parallel circuit bụ a yiri resonance etiti ugboro ọkụ. N’oge usoro mgbaze, karịsịa maka agbaze aluminum, ọla kọpa na ihe ndị ọzọ, ibu dị nnọọ mfe, na ike ya dị nnọọ obere, nke nwere ọtụtụ ihe jikọrọ ya na ọdịdị nke ibu ahụ, ya mere ọsọ ọsọ ya na-agbaze ngwa ngwa , Ihe isi ike. na kpo oku elu. The thyristor usoro intermediate ugboro agbaze ọkụ na-edozi ike site ugboro modulation, otú ọ bụ dịtụ obere mmetụta site na ọdịdị nke ibu. Usoro dum nke ịgbaze ọ fọrọ nke nta ka ọ nọgide na-enwe mmepụta ike mgbe niile. N’ihi na ọ bụ usoro resonance, ya bụ, voltaji resonance, induction coil voltaji dị elu na nke ugbu a dị obere, ya mere ọnwụ ike dị obere.

2. N’ihi na ọ bụ usoro inverter usoro, ihe ike na-akpata dị elu na harmonics dị ntakịrị, n’ihi ya, ọ dịghị mkpa ịwụnye ngwaọrụ nkwụghachi ụgwọ ọrụ. Nke a nwere ike ịzọpụta ndị ọrụ nnukwu ego, ọ bụkwa akụrụngwa dị elu nke ngalaba na-enye ọkụ na-akwalite ike.

3. Mgbe usoro etiti ugboro ọkụ na-arụ ọrụ, na rectifier mgbe niile na-arụ ọrụ na n’ụzọ zuru ezu-na ala, na mmepụta ike nke inverter circuit gbanwere site ịchịkwa inverter ịkpalite usu ugboro. Na ibu ugbu a bụ sine ife, otú usoro etiti ugboro ọkụ agaghị kpọrọ merụọ ike okporo na elu harmonics, na ike ihe dị elu. Parallel inverters enweghị ike nweta otu-na-abụọ akpaka ike ukpụhọde ọrụ, n’ihi na ike ukpụhọde nke yiri inverter ike ọkọnọ nwere ike nweta naanị site n’ịgbanwe voltaji mmepụta nke rectifier akwa. Mgbe parallel inverter rectifier akwa na-arụ ọrụ na obere voltaji, ihe rectifier conduction akụkụ dị nnọọ obere. Na steeti, ike ihe nke akụrụngwa ga-adị nnọọ ala, na myirịta inverter ibu ugbu a bụ a square ife, nke ga-merụsịrị grid. Ọ bụrụ na a na-edozi ike site n’ịgbanwe n’akụkụ nrụgide inverter azụ, oke ngbanwe ike dị warara. Ya mere, myirịta ike inverter ike nweta otu-na-abụọ ọrụ.
