Uhlalutyo lweZizathu zoKufudumeza okugqithisileyo kweTransformer

Uhlalutyo lweSizathu sokuFudumeza ngokugqithisileyo kweTransformer

Mna, unobangela wokusilela kwe-transformer ngokwayo

Ngexesha lokusebenza kwe-transformer, xa ukuveliswa kobushushu kunye nokuchithwa kobushushu kufikelela kwimeko yokulinganisela, ubushushu benxalenye nganye buhlala buzinzile. Ukuba phantsi kweemeko ezifanayo, ubushushu beoyile buphezulu kunesiqhelo ngaphezu kwe-10°C, okanye umthwalo uhlala ungatshintshi, kodwa ubushushu buqhubeka nokunyuka, kunokucingelwa ukuba kukho impazamo eyenzekileyo ngaphakathi kwe-transformer.

1. Unxibelelwano olubi lwesixhobo sokutshintsha itephu

Ngenxa yoxinzelelo olunganelanga lwendawo yoqhagamshelwano lwe-tap changer ngexesha lokusebenza okanye ungcoliseko lwendawo yoqhagamshelwano, uxhathiso loqhagamshelwano luyanda. Ukwanda koxhathiso loqhagamshelwano kuya kubangela ukuba ubushushu boqhagamshelwano bunyuke kwaye buvelise ubushushu. Ingakumbi emva kokutshintsha iimpompo kwaye xa i-transformer igcwele kakhulu, kulula ukwenza i-tap changer ingadibani kakuhle kwaye ivelise ubushushu.

Ukudibana kakubi kwesixhobo sokutshintsha itephu kunokugwetywa ngokusebenza rhoqo kwegesi ekhanyayo, kwaye ngokuthatha iisampulu zeoyile ukuze kuvavanywe, kunokufunyanwa ukuba ukudibana okubi kwesixhobo sokutshintsha itephu kwenza ukuba i-oyile flash point yehle ngokukhawuleza; ukongeza, itephu inokufunyanwa ngokulinganisa ixabiso le-DC resistance yekhoyili. Imeko yokunxibelelana kweswitshi.

2. Isekethe emfutshane ye-coil ejikajikayo ukuya kwejika

Ngenxa yomonakalo wokufakelwa kwe-insulation phakathi kokujika okukufutshane kwe-coil, kuya kuvela umsinga ojikelezayo we-short-circuit circuit ovaliweyo. Kwangaxeshanye, inani lokujika kwe-coil yale nqanaba liyancitshiswa, kwaye ubushushu obuphezulu obuveliswa ngumsinga ojikelezayo we-short-circuit buza kubangela ukunyuka kobushushu be-transformer kube phezulu kakhulu, kwaye kwiimeko ezinzima, i-transformer iya kutshiswa.

Kukho izizathu ezininzi zokuba kubekho i-short circuit phakathi kokujika kwe-coil. Umzekelo, inkqubo yokwenziwa kwe-coil erhabaxa ibangela ukuba i-insulation yonakale ngoomatshini; ubushushu obuphezulu bubangela ukuba i-insulation iguge; Izizathu eziphambili kukuba i-overvoltage kunye ne-overcurrent. I-short-circuit enzima yokujika ukuya ekujikeni yenza ukuba ubushushu be-oyile bunyuke, kwaye i-oyile ekujikeni kwe-short-circuit ibonakala ngathi iyabila, kwaye isandi "sokugungqa" sinokuvakala. Xa isampuli yeoyile yathathwa ukuze ivavanywe, umgangatho weoyile wehla kwaye waphuhliswa ukusuka kwisenzo segesi esilula ukuya kwisenzo segesi esinzima. Ngeli xesha, i-short circuit yokujika phakathi inokufumaneka ngokulinganisa ukumelana kwe-DC.

3. Umjikelo omfutshane phakathi kwamaphepha esinyithi esinyithi e-silicon

Ngenxa yomonakalo wamandla angaphandle okanye ukuguga kwe-insulation kunye nezinye izizathu, i-insulation phakathi kwamaphepha esinyithi e-silicon iyonakala, i-eddy current iyanda, kwaye kubangelwa ubushushu obuphezulu bendawo. Ukongeza, umonakalo kwi-insulation ye-core screw nayo yimbangela ye-eddy current. Ukukhanya okubangela ukufudumeza kwendawo, kwaye ngokubanzi ukunyuka kobushushu be-transformer oil akunakubonwa; Intshukumo enzima yegesi kwiimeko ezinzima.

4. Ukungabikho kweoyile okanye ukuvaleka kombhobho wokupholisa

Ioyile yetransformer yeyona nto iphambili ekugqumeni ngaphakathi kwitransformer, edlala indima yokugquma, ukupholisa kunye nokucima i-arc. Ukuba kukho ukunqongophala kweoyile okanye ingaphakathi lombhobho wokusasaza ubushushu livaliwe, isantya sokupholisa sokuhamba kweoyile siya kuncipha, nto leyo eya kubangela ukuba ubushushu betransformer bunyuke ngexesha lokusebenza.

II. izizathu zangaphandle zobushushu obuphezulu be-transformer

1. Ukugqithisa kakhulu

Ngexesha lokusebenza kwe-transformer, ukulahleka kwe-hysteresis kwe-iron core, ukulahleka kwe-eddy current kunye nokulahleka kwe-copper kwe-coil konke kuguqulwa kube bubushushu, okwenza ubushushu bunyuke. Ukulahleka kwe-iron kukulahleka okuhlala kuhleli, okunxulumene nesakhiwo se-transformer, ngoko ke akunakuncitshiswa okanye kususwe ngexesha lokusebenza, ngelixa ukulahleka kwe-copper kutshintsha ngokutshintsha komthwalo. Xa umthwalo unzima, ukwanda kokulahleka kwe-copper kuya kubangela ukuba ubushushu be-transformer bunyuke.

2. Ukungena komoya kunye nendawo yokuphuma yegumbi le-transformer ivaliwe okanye uthuli lubi kakhulu

Ukungena komoya kunye nendawo yokuphuma kwegumbi le-transformer ziindlela zokuhambisa umoya ngexesha lokusebenza kwe-transformer. Nje ukuba ivalwe okanye ixutywe kakhulu, iimeko zokufudumeza ze-transformer azitshintshi kodwa iimeko zokuchitha ubushushu ziba mandundu, kwaye ubushushu abunakusasazeka kwindawo engqongileyo ngexesha, nto leyo ebangela ukunyuka kobushushu be-transformer ngexesha lokusebenza. Linganisa ubushushu bomoya kwindawo eyi-1.5m ukuya kwi-2m ukusuka kwitanki yeoyile ye-transformer kunye nesiqingatha sokuphakama kwetanki yeoyile. Ukuba ubushushu obulinganisiweyo buphezulu nge-8-10°C kunobushushu bomoya obungqongileyo, kufuneka kuphuculwe umoya wegumbi le-transformer.

3. Ukusilela kwenkqubo yomjikelo wokupholisa wetransformer

Ukongeza ekusebenziseni imibhobho yokupholisa ukuphelisa ubushushu, ii-power transformers zikwanazo neendlela zokupholisa ezifana nokupholisa umoya ngokunyanzeliswa, ukujikeleza kweoyile ngokunyanzeliswa, kunye nokujikeleza kwamanzi. Xa inkqubo yokupholisa ingaphumeleli okanye iimeko zokupholisa zingaba zimbi, ubushushu be-transformer esebenzayo buya kunyuka.
