Insulation mlingo wa thiransifoma

Monga zida zofunikira zamagetsi mumagetsi amagetsi, mulingo wotsekemera wa transformer umagwirizana mwachindunji ndi magwiridwe antchito otetezeka komanso okhazikika amagetsi. Mulingo wa kutchinjiriza ndi kuthekera kwa thiransifoma kupirira ma overvoltages osiyanasiyana komanso voteji yanthawi yayitali yogwira ntchito panthawi yogwira ntchito, ndipo ndichinthu chofunikira kwambiri chomwe sichinganyalanyazidwe pakupanga, kupanga, kugwira ntchito ndi kukonza thiransifoma.

1. Tanthauzo la mulingo wotsekemera wa thiransifoma Mulingo wotsekemera umatanthawuza kuthekera kwa kapangidwe ka thiransifoma kukhalabe kukhulupirika ndi chitetezo pamene imalimbana ndi ma overvoltages osiyanasiyana komanso ma voltages anthawi yayitali. Izi zikuphatikiza mulingo wamagetsi womwe ungaloledwe molumikizana ndi chomangira mphezi yoteteza ndipo mwachindunji zimadalira mphamvu yayikulu ya Um ya zida.

2. Mapangidwe opangira magetsi a thiransifoma Malingana ngati mulingo wotsekemera wa mzere wokhotakhota umatha ndi malo osalowererapo ndi ofanana, thiransifoma ikhoza kugawidwa m'magulu awiri otsekemera: kutsekemera kwathunthu ndi kutsekemera kwapakati. The thiransifoma ndi zonse kutchinjiriza dongosolo ali ndi chimodzimodzi kutchinjiriza mlingo wa mapeto a mzere wokhotakhota ndi mfundo ndale, ndi apamwamba kutchinjiriza malire, ndipo ndi oyenera thiransifoma ndi milingo mkulu voteji ndi madera ovuta ntchito. Transformer yokhala ndi grade insulation structure imayika milingo yosiyanasiyana yotsekera pakati pa malekezero a mzere wokhotakhota ndi malo osalowererapo malinga ndi zofunikira zenizeni kuti mukwaniritse kapangidwe kake ndikuchepetsa mtengo.

3. Kuyesedwa kwa mlingo wa kusungunula kwa transformer Kuonetsetsa kuti mlingo wotsekemera wa transformer umakwaniritsa zofunikira za mapangidwe, mndandanda wa mayesero otsekemera amafunikira. Kwa ma transformer okhala ndi mulingo wa voteji wa 220kV ndi pansi, mphindi imodzi yamphamvu yamagetsi yolimbana ndi kuyesa kwamagetsi ndi kuyesa kwamagetsi amagetsi nthawi zambiri kumachitika kuti awone mphamvu zawo zotsekereza. Kwa ma transfoma omwe ali ndi milingo yayikulu yamagetsi, kuyezetsa kwamphamvu kwambiri kumafunikanso. M'mayesero a fakitale, kuyesa kwamagetsi kupirira nthawi zambiri kumachitika mowirikiza kawiri ma voliyumu ovotera nthawi imodzi kuwunika momwe ntchito yotchingira imagwirira ntchito komanso kutsekereza kotalika.

Kuphatikiza apo, kuyeza kukana kwa insulation, chiŵerengero cha mayamwidwe ndi polarization index of the windings pamodzi ndi bushing ndi njira yofunikira yowunikira momwe thiransifoma imakhalira. Miyezo iyi imatha kuzindikira bwino chinyezi chonse cha kusungunula kwa thiransifoma, chinyezi kapena dothi pamwamba pazigawozo, komanso zolakwika zolowera.

4. Zomwe zimakhudza mlingo wa kusungunula kwa transformer Panthawi yogwiritsira ntchito thiransifoma, zinthu zomwe zimakhudza mlingo wa kusungunula makamaka zimaphatikizapo kutentha, chinyezi, njira yotetezera mafuta ndi zotsatira za overvoltage. 1) Kutentha: Kutentha ndichinthu chofunikira kwambiri chomwe chimakhudza magwiridwe antchito a thiransifoma. Kutentha kwazinthu zotetezera kumachepa ndi kuwonjezeka kwa kutentha, ndipo kukhalapo kwa chinyezi mu mafuta kudzafulumizitsanso kukalamba kwa kutsekemera. Choncho, kulamulira kutentha ntchito ya thiransifoma ndi kusunga chikhalidwe chabwino cha insulating zakuthupi ndi njira zofunika kusintha mulingo kutchinjiriza.

2) Chinyezi: Kukhalapo kwa chinyezi kumathandizira kukalamba kwa zinthu zoteteza ndikuchepetsa ntchito yake yotchinjiriza. Chifukwa chake, panthawi yogwira ntchito ya thiransifoma, chinyezi chozungulira chiyenera kuyendetsedwa mosamalitsa kuti zinthu zotchingira zisawonongeke.

3) Njira yotetezera mafuta: Njira zosiyanasiyana zotetezera mafuta zimakhala ndi zotsatira zosiyana pa ntchito yotsekemera. Popeza mafuta pamwamba pa thiransifoma yosindikizidwa ndi insulated kuchokera mlengalenga, amatha kuteteza kusungunuka ndi kufalikira kwa CO ndi CO2 mumafuta, potero kusunga ntchito yabwino ya mafuta otetezera.

4) Zotsatira za Overvoltage: Zotsatira za overvoltage ndi chinthu china chofunikira chomwe chimakhudza mulingo wa kutchinjiriza kwa thiransifoma. Kuchuluka kwa mphezi komanso kuwonjezereka kwamagetsi kungayambitse kuwonongeka kwa kapangidwe ka thiransifoma. Chifukwa chake, popanga ndikugwiritsa ntchito thiransifoma, kukhudzidwa kwa overvoltage kuyenera kuganiziridwa mokwanira ndipo njira zodzitetezera ziyenera kuchitidwa.

5. Njira zowonjezerera mulingo wa kutchinjiriza kwa thiransifoma
Kuti muwonjezere mulingo wa insulation ya transformer, njira zotsatirazi zitha kuchitidwa:
1) Sankhani zida zapamwamba zotchingira: Zida zapamwamba zotchingira zimakhala ndi magwiridwe antchito abwino komanso moyo wautali wautumiki, womwe ungathe kusintha kwambiri mulingo wa thiransifoma.
2) Konzani kamangidwe ka kutchinjiriza: Malinga ndi malo enieni ogwirira ntchito ndi zofunikira za thiransifoma, konzani kapangidwe kake ndikuyika malire otsekera kuti mutsimikizire kuti chosinthiracho chimatha kukhalabe ndi ntchito yabwino yotchinjiriza pansi pamikhalidwe yosiyanasiyana yogwirira ntchito.
3) Limbikitsani kuyang'anira ndi kukonza zotchingira: Onetsetsani nthawi zonse ndikusunga kutentha kwa thiransifoma, zindikirani mwachangu ndikuthana ndi zovuta zotchingira ndi ukalamba, ndikuwonetsetsa kuti mulingo wa thiransifoma nthawi zonse umasungidwa pamalo apamwamba.
4) Tekinoloje yolimbikitsira ukadaulo: Potengera ukadaulo wowonjezera kutentha, mafunde a asoblique, spiral kapena cosine wave boosting, mulingo wa kutchinjiriza wa thiransifoma ukhoza kutsogola kwambiri ndipo mphamvu zake zotsutsana ndi kusokoneza komanso kulolerana zitha kupitilizidwa.
Mwachidule, mulingo wa kutchinjiriza wa thiransifoma ndi chinthu chofunikira kwambiri pakugwira ntchito kwake kotetezeka komanso kokhazikika. Mwa kusankha zida zapamwamba zotchinjiriza, kukhathamiritsa kapangidwe kake, kulimbitsa kuwunikira ndi kukonza, komanso kutengera ukadaulo wowonjezera kutentha, mulingo wa thiransifoma ukhoza bwino bwino ndipo moyo wake wautumiki ukhoza kukulitsidwa.
