Izizathu zovavanyo lwempembelelo yabaguquli abatsha okanye abaguquli-ziguquli emva kokulungiswa kwakhona ngaphambi kokuba baqalise ukusebenza ngokusemthethweni zezi zilandelayo:
(1) Khangela i-insulation ye-transformer kunye neesekethe zayo zobuthathaka okanye iziphene. Xa i-transformer engekho-load ikhutshwe ngaphandle, kunokwenzeka ukuvelisa i-overvoltages yokusebenza. Xa indawo engathathi hlangothi yenkqubo yamandla ingamiselwanga okanye isekelwe kwi-coil yokunciphisa i-arc, i-amplitude yokugqithisa i-overvoltage inokufikelela ku-4-4.5 amaxesha ombane wesigaba; xa indawo engathathi hlangothi isekelwe ngokuthe ngqo, i-overvoltage amplitude inokufikelela kumaxesha angama-3 i-voltage yesigaba. Ukuze ukhangele ukuba amandla okugquma kwe-transformer anokumelana nefuthe le-voltage epheleleyo okanye i-overvoltage yokusebenza, kuyimfuneko ukwenza uvavanyo olupheleleyo lwe-voltage impulse engenalo umthwalo ngaphambi kokuba i-transformer isetyenziswe. Ukuba i-transformer kunye neesekethe zayo zinobuthathaka be-insulation, ziya kubonakaliswa ekusebenzeni ukuchithwa kwe-overvoltage.
(2) Khangela ukuba ukukhuselwa okwahlukileyo kwe-transformer ayisebenzi kakuhle. Xa i-transformer engekho-load inikwe amandla, i-inrush current iya kuveliswa, kwaye ixabiso layo linokufikelela kumaxesha angama-6-8 ngoku. I-magnetizing inrush yangoku iqala ukuthothisa ngokukhawuleza, ngokubanzi inokuncitshiswa ukuya ku-0.25-0.5 amaxesha alinganisiweyo ngoku emva kwe-0.5-1s, kodwa kuthatha ixesha elide ukuba konke ukuthotywa kugqitywe, malunga nemizuzwana embalwa kumlinganiselo omncinci kunye nophakathi. i-transformers, kunye ne-10-20 ye-transformers enkulu, ngoko i-magnetizing inrush yangoku iyancipha Kwinqanaba lokuqala, ukukhuselwa kokwahlukana kudla ngokungahambi kakuhle, kubangela ukuba i-transformer ingakwazi ukufakwa ekusebenzeni. Ngoko ke, xa ukuvalwa kwempembelelo yokungabikho komthwalo, phantsi kwesenzo se-excitation inrush current, i-wiring, iimpawu kunye nokusetwa kokhuseleko lokwahlukana kunokuhlolwa ngokwenene, kunye novavanyo kunye nesiphelo sokuba ukhuseleko lunokufakwa. yenziwe.
(3) Jonga amandla omatshini we-transformer. Ekubeni i-excitation inrush current ivelisa isixa esikhulu samandla ombane, ukwenzela ukuvavanya amandla omatshini we-transformer, uvavanyo lwempembelelo yokungabikho komthwalo luyafuneka.
Ngokwemigaqo, inani lovavanyo lwempembelelo ye-voltage epheleleyo yokungabikho komthwalo kufuneka ichaphazeleke ngokuqhubekayo ngamaxesha e-5 xa iimveliso ezintsha zifakwa ekusebenzeni; emva kolungiso, kufuneka ichaphazeleke ngokuqhubekayo ngamaxesha ama-3. Ikhefu phakathi kwempembelelo nganye ayikho ngaphantsi kwe-5min. Ngaphambi kokusebenza, umntu kufuneka athunyelwe kwindawo yokubeka iliso kwi-transformer ukujonga ukuba kukho ukungaqhelekanga kwi-transformer. Ukuba kukho nakuphi na ukungaqhelekanga, utyando kufuneka lunqunyanyiswe ngoko nangoko.
Emva kwempembelelo yokuqala, kufuneka iqhubeke isebenza ngaphezu kwemizuzu eyi-10, kwaye impembelelo elandelayo kufuneka ilinde ngaphezu kwemizuzu emi-5 ngaphambi kwempembelelo elandelayo. Ngokumalunga nokuba kutheni ibekwe kumaxesha e-5, ichazwe kwimimiselo, kwaye uqikelelo oluthile sisigqibo esithathwe kuqwalaselo olubanzi lwamandla omatshini, ukugqithisa kunye nokuvuselela ngokungena ngokuqhubekayo.
