Kungenzeka kangakanani ukuthi i-transformer enemvamisa ephansi yehluleke
Amathuba okwehluleka ayahlukahluka kuye ngendawo.
Sebenzisa i-multimeter ukukala ikhwalithi ye-transformer enemvamisa ephansi
1. Ukutholwa okuqondile ngegiya elinamandla
Amanye ama-multimeter edijithali anomsebenzi wokulinganisa amandla, futhi amabanga awo okulinganisa angama-2000p, 20n, 200n kanye no-2 μ kanye no-20 μ igiya lesihlanu. Ngesikhathi sokulinganisa, amaphini amabili e-capacitor akhishwe angafakwa ngqo ku-Cx jack ebhodini lemitha. Ngemva kokukhetha ububanzi obufanele, idatha yokubonisa ingafundwa futhi i-transformer ingahlulelwa.
2. Thola ngegiya lokumelana
Inqubo yokushaja ye-capacitor ingabonakala futhi nge-digital multimeter, ekhombisa ushintsho lwe-voltage yokushaja ngamanani edijithali ahlukene. Uma izinga lokulinganisa le-digital multimeter liyi-n times/second, khona-ke ngesikhathi sokubuka inqubo yokushaja ye-capacitor, ukufundwa kwe-n okuzimele nokukhula ngokulandelana kungabonakala njalo ngomzuzwana. Ngokusho kwalesi sici sokubonisa se-digital multimeter, ikhwalithi ye-capacitor ingatholakala futhi amandla angalinganiswa.
Qaphela: Isimiso sokuthola kanye nendlela kuyafana kokubili kwi-transformer enemvamisa ephezulu kanye ne-transformer enemvamisa ephansi.
Ukulungiswa Kwephutha Kwe-Low Frequency Transformer
Ukuhlukaniswa kanye nezimbangela zamaphutha avamile kuma-transformer
(1) Izinkinga ezikhona lapho i-transformer ilethwa. Njengeziphetho ezikhululekile, amabhlogo e-cushion akhululekile, ukushisela okubi, ukuvikela okuphansi kwe-core, amandla anele okujikeleza okufushane, njll.
(2) Ukuphazamiseka komugqa. Ukuphazamiseka komugqa kuyisici esibaluleke kakhulu kuzo zonke izici ezibangela izingozi ze-transformer. Kuhlanganisa kakhulu: i-over voltage ekhiqizwa ngesikhathi sokuvala, ukuphakama kwe-voltage esigabeni somthwalo ophansi, iphutha lomugqa, i-flash over nezinye izinto ezingavamile. Lolu hlobo lwephutha luthatha ingxenye enkulu kumaphutha e-transformer. Ngakho-ke, ukuhlolwa kokuvikela umfutho kumele kwenziwe njalo ku-transformer ukuze kutholakale amandla e-transformer ngokumelene nomsinga wokungena.
(3) Ijubane lokuguga kwe-transformer insulation elibangelwa ukusetshenziswa okungafanele liyasheshiswa. Isilinganiso sempilo yesevisi yama-transformer ajwayelekile siyiminyaka engu-17.8 kuphela, okuphansi kakhulu kunesikhathi senkonzo esilindelekile seminyaka engu-35-40.
(4) Amandla kagesi angaphezu kwamandla abangelwa ukushaywa umbani.
(5) Ukulayisha ngokweqile. Ukulayisha ngokweqile kubhekisela ku-transformer esesimeni sokusebenza sokudlula amandla e-nameplate isikhathi eside. Ukulayisha ngokweqile kuvame ukwenzeka lapho isitshalo samandla siqhubeka nokwandisa umthwalo kancane kancane, idivayisi yokupholisa isebenza ngendlela engajwayelekile, iphutha langaphakathi le-transformer, njll., futhi ekugcineni libangela ukuthi i-transformer ilayishe ngokweqile. Ukushisa okweqile okubangelwayo kuzoholela ekugugeni kwangaphambi kwesikhathi kwe-insulation. Lapho ikhadibhodi yokuvikela yokuguqula iguga, amandla ephepha azoncipha. Ngakho-ke, umthelela wamaphutha angaphandle ungaholela ekulimaleni kwe-insulation, okungaholela emaphutheni.
(6) Ukumanzisa: uma kukhona izikhukhula, ukuvuza kwepayipi, ukuvuza kwesembozo sekhanda, ukungena kwamanzi ethangini likawoyela eceleni kwesikhafu noma izesekeli, futhi kukhona amanzi ku-oyela wokuvikela, njll.
(7) Ukulungiswa okufanele akwenziwanga.
