Xa i-transformer core ibekwe ndawonye, ​​zeziphi iindlela zomthungo? Zithini iimpawu zayo nganye nganye? Eli nqaku liqala kwisayensi edumileyo yee-iron cores, kwaye liyakhula kwaye likwandise ukujonga indlela yomthungo yeeshiti zesinyithi ze-silicon xa ii-transformer iron cores zibekwe ndawonye. (Ukuba kukho naziphi na iimpazamo okanye izongezo, nceda ushiye umyalezo ekupheleni kwenqaku)

I-grounding transformer ibizwa ngokuba yi-grounding transformer ngamafutshane. Ngokwe-filling medium, i-grounding transformer inokwahlulwa ibe yi-oyile kunye ne-dry type; Ngokwenani lezigaba, i-grounding transformer inokwahlulwa ibe yi-grounding transformer yesigaba esithathu kunye ne-grounding transformer yesigaba esinye. Umsebenzi we-grounding transformer kukubonelela ngendawo engathathi hlangothi yokwenziwa kwenkqubo ene-underground neutral point, elungele ukusetyenziswa kwe-arc compression coil okanye i-grounding mode encinci yokumelana, ukuze kuncitshiswe i-capacitance current ukuya emhlabeni xa kuthe kwafakwa i-ground short circuit fail kwinethiwekhi yokusasaza kwaye kuphuculwe ukuthembeka kokunikezelwa kwamandla kwenkqubo yokusasaza.

Kukho izizathu ezibini eziphambili zokuvuza kweoyile yetransformer: kwelinye icala, iingxaki ezishiyekileyo kwinkqubo yoyilo lwetransformer kunye nenkqubo yokwenziwa kwayo; Kwelinye icala, ukuvuza kubangelwa kukufakelwa nokugcinwa kwayo ngendlela engafanelekanga. Iindawo eziphambili zokuvuza zetransformer zihlala zivela kwindawo yokujonga iradiator, isiciko sevalvu yebhabhathane esithe tyaba, isingxobo, ibhotile yeporcelain, i-weld, umngxuma wesanti, iflange kunye nezinye iindawo.

Ukhuseleko lwegesi lolona khuselo luphambili kwiimpazamo zangaphakathi zetransformer. Ingasebenza ngononophelo kwiisekethe ezimfutshane zetransformer eziphakathi kunye neze-inter-layer, iimpazamo zentsimbi, iimpazamo ze-bushing zangaphakathi, ukunqanyulwa kwe-insulation yangaphakathi, ukonakala kwe-insulation kunye nokuwa kwenqanaba leoyile. Xa kukho impazamo ngaphakathi kwetransformer entywilisiweyo kwioyile, i-arc iya kubolisa izinto zokukhusela kwaye ivelise inani elikhulu legesi, eliphuma kwitanki yeoyile ukuya kumqamelo yeoyile, kwaye ubunzulu bayo buyahluka ngokobunzima bempazamo, okubonakalisa ukuhamba komoya kunye nokuhamba kweoyile. Ukhuseleko lwesenzo lubizwa ngokuba lukhuselo lwegesi, olukwabizwa ngokuba lukhuselo lwegesi. Ngexesha lokusebenza kwetransformer, ngenxa yeempazamo zangaphakathi, ngamanye amaxesha asikwazi ukuchonga nokuthatha amanyathelo ngexesha, okulula ukubangela ezinye iingozi. Emva kokukhuselwa kwe-relay yegesi, ukwenzeka kweziganeko ezifanayo kunokuthintelwa ukuya kwinqanaba elithile.

1. Yintoni i-transformer?


Kwisekethe ye-AC, isixhobo esonyusa okanye esinciphisa i-voltage sibizwa ngokuba yi-transformer. I-transformer inokuguqula naliphi na ixabiso le-voltage libe lixabiso le-voltage esilifunayo nge-frequency efanayo ukuhlangabezana neemfuno zokuhambisa, ukusasaza kunye nokusetyenziswa kwamandla ombane.


Umzekelo, umbane ovela kwisikhululo samandla unenqanaba eliphantsi le-voltage, kwaye i-voltage kufuneka yonyuswe ngaphambi kokuba ithuthwe iye kwindawo ekude yokusebenzisa umbane. Indawo yokusebenzisa umbane kufuneka incitshiswe ibe kwinqanaba elifanelekileyo le-voltage ukuze kubonelelwe ngezixhobo zombane kunye nombane wemihla ngemihla. Izixhobo.

I-power transformer yindawo ephambili yokudlulisa nokusasaza amandla ombane, kwaye yeyona nto iphambili kwigridi yamandla. Ukusebenza kwayo okuthembekileyo akuhambelani nje kuphela nomgangatho wamandla wabasebenzisi abaninzi, kodwa kukwanxulumene nokhuseleko lwenkqubo yonke. Ukuthembeka kwe-power transformer kuxhomekeka kwimeko yayo yempilo, akuxhomekekanga kuphela kuyilo kunye nokuveliswa, izixhobo zokwakha, kodwa kukwanxulumene kakhulu nokulungiswa kunye nokugcinwa. Ingxaki yokuphucula ukumelana kwe-short-circuit ye-transformers kwiinkqubo zamandla iyaxoxwa.
