Kodi ma frequency frequency reaction a transformer winding ndi chiyani?

Transformer mapindikidwe mapindikidwe amatanthauza kusintha kosasinthika kukula ndi mawonekedwe a mapindikidwe pansi pa zochita za makina ndi magetsi.Zimaphatikizapo kusintha kwa miyeso ya axial ndi ma radial, kusamuka kwa thupi, kupindika kokhotakhota, kuphulika ndi kabudula wapakati, ndi zina zotero.Makamaka zovulaza thiransifoma.

Ngakhale kuti wosweka dera amatha kuthetsa vuto lachidule la dera, chipangizo chodziwikiratu nthawi zambiri sichigwira ntchito pazifukwa zina, kotero kuti koyilo ya thiransifoma imapunduka pakapita nthawi yochepa kwambiri. kutentha, magetsi, ngakhale kwambiri interphase short-circuit ndi Mapiringidzo ndi kuwotchedwa;nthawi yomweyo, thiransifoma imathanso kugwedezeka ndikukhudzidwa panthawi yoyendetsa ndi kukhazikitsa, zomwe zimapangitsa kuti pakhale mapindikidwe, zingwe zosweka, kusamuka, kumasula ndi zochitika zina.

Kodi cholinga choyezetsa kusintha kwa transformer winding ndi chiyani?

A: Kupindika kwa mphepo ndi ngozi yaikulu yobisika ku ntchito yotetezeka yamagetsi.M'zaka zaposachedwa, ndi kuwonjezeka kwa mphamvu ya mphamvu yamagetsi, mphamvu yafupikitsa yowonjezera ikuwonjezeka, ndipo ngozi yowonongeka kwa mawondo chifukwa cha kufupikitsa kwa mzere wotuluka ikukweranso.

Pambuyo popindika chopindika cha thiransifoma, choyamba ndikusintha mtunda wa kutchinjiriza kapena kuwonongeka kwa pepala lotsekera.Pamene overvoltage ikukumana, ma windings adzakhala ndi inter-keke kapena inter-turn breakdown, kapena pansi pa mphamvu ya nthawi yayitali yogwira ntchito, kuwonongeka kwa insulation kumakula pang'onopang'ono, pamapeto pake kumatsogolera ku transformer.Kuwonongeka: Chachiwiri, pamene mapiringirowo apunduka, mphamvu zamakina zimachepa.Pakachitika ngozi yachidule yozungulira, chifukwa sichingathe kupirira mphamvu yayikulu, ngozi yowonongeka idzachitika, ndipo imatha kugwirabe ntchito kwa nthawi yayitali.

Transformer winding deformation ndi chimodzi mwa zifukwa zofunika zowonongeka kwa thiransifoma.Kuyesa kwamagetsi wamba monga kuyeza kukana, kuyeza kwa chiŵerengero cha kusintha, ndi kuyeza kwa capacitance ndizovuta kupeza mapindikidwe opindika, omwe angawononge kwambiri ntchito yotetezeka ya gridi yamagetsi.Pachifukwa ichi, m'pofunika kwambiri kuti azindikire ndi kuzindikira mapindikidwe a thiransifoma windings pansi mawotchi ndi mphamvu zamagetsi.
