Iindaba zeShishini

Ngokungafaniyo nokulahleka kobhedu, ukulahleka kwesinyithi kwetransformer akuxhomekekanga kwizinto ezifana nokujika kunye nobukhulu bangoku. Ngokwembono yegama, ukonakala kwesinyithi kunxulumene kakhulu nesinyithi, kuveliswa yintsimbi engundoqo. Ukulahleka kwesinyithi kwetransformer kwaziwa ngokuba "kukulahleka komthwalo", oku kungenxa yokuba ukulahleka kwesinyithi kuhlala kukho kwitransformer, nokuba ngumthwalo opheleleyo okanye umthwalo ongekhoyo, kwaye kuxhomekeke ekulahlekelweni okusisigxina kwetransformer. Nangona kunjalo, ngexesha lenkqubo yomthwalo, ukulahleka kwamandla kuya kuncipha ngokuncipha kwamandla ombane.

Iitransformer ze-voltage ephezulu zisebenza njengezixhobo ezibalulekileyo ekudluliseni umbane nakwimveliso yemizi-mveliso, kunye nezicelo eziquka amandla, imveliso, ukhathalelo lwempilo, kunye namanye amacandelo abalulekileyo. Eli nqaku liphonononga iindima ezibalulekileyo zeetransformer ze-voltage ephezulu kuluntu lwanamhlanje ngokusebenzisa imigaqo yobugcisa, iimeko zesicelo, kunye nezifundo zamatyala zoshishino.

Ngokuphuhliswa kweenjongo zokungathathi cala kwekhabhoni, ukusebenza kakuhle kwamandla okuguqula kuye kwaba yindlela ephambili yokulinganisa amashishini ukunciphisa iindleko zokusebenza nokufezekisa uxanduva loluntu. Ngokusekelwe kwimigangatho yesizwe efanaI-GB 20052-2024, eli nqaku libonelela ngohlalutyo olunzulu lweeklasi zokonga amandla, iindlela zokuvavanya, kunye namaqhinga okukhetha ukunceda abasebenzisi bafikelele ekongeni amandla.

IiTransformers zohlobo olomileyo:

Ukufakwa kwe-insulation: I-Epoxy resin casting okanye i-non-encapsulated solid insulation (umz., iphepha le-Nomex).

Ulwakhiwo: Ii-core/windings ezibonakalayo ezinee-bushings zerabha ze-silicone.

IiTransformers ezintywiliselwa kwiOyile:

Ubushushu: Ioyile yeminerali okanye ye-ester eyenziweyo; ifakwa ngokupheleleyo etankini.

Ulwakhiwo: Itanki evaliweyo enezikhonkwane zeporcelain.

Njengenxalenye ephambili kwigridi yombane, ii-power transformers ziphambili kwindlela esisasaza kwaye sisebenzise ngayo umbane. Kodwa umbane ohamba phakathi kwezi transformers uza ngeendlela ezimbini eziphambili: i-Alternating Current (AC) kunye ne-Direct Current (DC). Ukuqonda umahluko kubalulekile ekuqondeni iinkqubo zamandla zanamhlanje.

Ii-transformers ze-alloy ezi-amorphous, ezinelahleko eziphantsi kakhulu kunye nokusebenza kakuhle kwamandla, ziye zavela njengezitshintshi zenguqu kwii-transformers zesinyithi ze-silicon zemveli. Eli nqaku lihlola imigaqo yazo yobugcisa, iingenelo, usetyenziso, kunye nokwamkelwa okuqhutywa yimigaqo-nkqubo ukukhokela ukwenziwa kwezigqibo ezinolwazi.

I-transformer entywilisiweyo ngeoyile luhlobo lwe-transformer yombane esebenzisa ioyile njengendlela yokukhusela nokupholisa. Le transformer isebenza ngokuguqula i-alternating current (AC) ukusuka kwinqanaba le-voltage ukuya kwelinye, nokuba yonyusa (inyuka) okanye yehlise (ihla) i-voltage. I-transformer ine-magnetic core, ii-windings, kunye ne-bushings, zonke zifakwe kwi-transformer oil, edlala indima ebalulekileyo ekugcineni ukusebenza kwesixhobo.

Kuya kufuneka uzazi izixhobo eziphambili kunye neendawo ezinceda ii-transformer zakho ezifakwe kwi-pad zisebenze ngokukhuselekileyo nangokufanelekileyo. Ii-bushings zivumela iingcingo ukuba zidlule kwibhokisi ye-transformer. Ii-tap changer zikuvumela ukuba ulungise amanqanaba ombane. Ii-fuses kunye ne-surge arresters zikhusela ii-transformer ezifakwe kwi-pad kwimiba kunye nokubethwa ngumbane. Iinkqubo zokumisa umhlaba ziqinisekisa ukhuseleko kuwo wonke umntu. Iigeyiji zokujonga, izixhobo zokunciphisa uxinzelelo, kunye nezibonakaliso zempazamo zinceda ekufumaneni iingxaki kwangethuba. Izixhobo zoomatshini zenza kube lula ukuhambisa nokufaka ii-transformer ezifakwe kwi-pad. Isixhobo ngasinye sibalulekile ukuze ii-transformer ezifakwe kwi-pad zisebenze ngokufanelekileyo.

Isitishi esingaphantsi kwesinyeisiguquliluhlobo oluthile lwe-transformer eyenzelwe ukuguqula amanqanaba ombane ngaphakathi kwesitishi esingaphantsi. Inceda ukudluliselwa kwamandla ombane ukusuka kwimigca yokudlulisela amandla aphezulu ukuya kumanqanaba ombane aphantsi afanelekileyo ukusasazwa kubathengi.

Iitransformer ezifakelwe iipad (ii-PMT) zezona ngqwele zingadunyiswanga zokusasazwa kombane kwanamhlanje. Njengezinto ezibalulekileyo kwiinethiwekhi zamandla zasezidolophini nasezidolophini, ezi yunithi zincinci, ezikumgangatho ophantsi zizisa umbane ngokukhuselekileyo emakhayeni, kumashishini nakwiziseko zophuhliso zikawonke-wonke. Kodwa yintoni kanye kanye eyenza ukuba zingabi yimfuneko?
