Momwe mungasinthire an Kuthetsa pafupipafupi thiransifoma?

The wapakatikati pafupipafupi kuzimitsa thiransifoma imafupikitsidwa ngati intermediate frequency transformer, yomwe imadziwikanso kuti matching transformer. Chojambula chake chikuwonetsedwa mu Chithunzi 2-14 posankha ma induction kutenthetsera ma frequency apano komanso kuyerekezera kwa mphamvu zamagetsi.

Chiyanjano chapakati pa ma voteji oyambilira (Ep) ndi voteji yachiwiri (Es) chikhoza kuwonetsedwa ndi chiŵerengero cha kutembenuka kwa mapiritsi awiriwa: Ep/Es=N/Ns. Ntchito yake makamaka kuchepetsa voteji, kotero kuti magawo a inductor zikugwirizana ndi magawo wapakatikati pafupipafupi magetsi. Pofuna kuchepetsa kutayika kwa zigawo zapakati pazigawo zamtundu wa ma frequency, mphamvu yamagetsi yomwe imagwiritsidwa ntchito ndi mphamvu yapakati pamagetsi imakhala pakati pa 375V ndi 1500V. Masiku ano, 650V ndi 750V amagwiritsidwa ntchito kwambiri. Magetsi a inductor omwe amagwiritsidwa ntchito pazida zozimitsa nthawi zambiri amakhala pakati pa 7 ndi 100V chifukwa chamitundu yosiyanasiyana. Pamagetsi apakatikati a 100kW, magetsi omwe amagwiritsidwa ntchito nthawi zambiri amakhala pakati pa 8 ndi 80V. Mwachitsanzo, magetsi ofunikira a crankshaft semi-annular inductor nthawi zambiri amakhala 65-80V pa 8-10kHz.

(1) Zofunikira zazikulu ndi zofunikira za thiransifoma yapakatikati ndi kV · A monga mphamvu yodziŵika. Zofunikira zaukadaulo za ma frequency apakati pafupipafupi ndizo: magwiridwe antchito okhazikika komanso odalirika, ntchito yabwino, kapangidwe kakang’ono, kutayika kochepa komanso mtengo wololera. Kuphatikiza apo, pali zofunika ziwiri zapadera:

1) The variable pressure coefficient ndi yosavuta kusintha.

2) Kuwonongeka kwafupipafupi kumakhala kochepa (izi ndizofunikira kuti muchepetse kusasunthika kwa kutentha kwa kutentha. Kusakhazikika kumeneku kudzachitika pamene thiransifoma sichimapunduka kwambiri, ndipo idzakhudza kukula kwa mpweya wochepa).
