Angakanani amathuba okuthi i-low-frequency transformer ihluleke
Amathuba okwehluleka ayahluka ngesayithi.
Sebenzisa i-multimeter ukukala ikhwalithi ye-low-frequency transformer
1.Ukutholwa okuqondile ngegiya le-capacitive
Amanye ama-multimeter edijithali anomsebenzi wokulinganisa amandla, futhi ububanzi bawo bokulinganisa buyi-2000p, 20n, 200n kanye no-2 μ Futhi 20 μ Igiya lesihlanu.Ngesikhathi sokulinganisa, izikhonkwane ezimbili ze-capacitor ekhishiwe zingafakwa ngokuqondile kujeke we-Cx ebhodini lamamitha.Ngemva kokukhetha ububanzi obufanele, idatha yokubonisa ingafundwa futhi i-transformer ingahlulelwa.
2. Thola ngegiya lokumelana
Inqubo yokushaja ye-capacitor ingabuye ibonwe nge-multimeter yedijithali, empeleni ebonisa ukuguqulwa kwe-voltage yokushaja ngamanani ahlukene edijithali.Uma izinga lokulinganisa le-multimeter yedijithali liyizikhathi ezingu-n / okwesibili, khona-ke ngesikhathi sokubhekwa kwenqubo yokushaja ye-capacitor, ukufundwa okuzimele nokukhula okulandelanayo kungabonakala njalo ngomzuzwana.Ngokusho kwalesi sici sokubonisa se-multimeter yedijithali, ikhwalithi ye-capacitor ingatholwa futhi i-capacitance ingalinganiswa.
Qaphela: Umgomo wokutholwa kanye nendlela kuyafana kukho kokubili i-high-frequency transformer kanye ne-low-frequency transformer.
Ukugcinwa Kwephutha Kwe-Low Frequency Transformer
Ukuhlukaniswa kanye nezimbangela zamaphutha ajwayelekile kuma-transformer
(1) Izinkinga ezikhona lapho i-transformer ilethwa.Okufana neziphetho ezixegayo, amabhulokhi e-cushion axegayo, ukushisela okungekuhle, ukufakwa kahle kwe-core, amandla wesekethe emfushane anganele, njll.
(2) Ukuphazamiseka komugqa.Ukuphazamiseka komugqa kuyisici esibaluleke kakhulu kuzo zonke izici ezibangela izingozi ze-transformer.Ihlanganisa ikakhulukazi: i-voltage engaphezu kwamandla akhiqizwa ngesikhathi sokuvalwa, 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 kufanele kwenziwe ku-transformer njalo ukuze kutholakale amandla e-transformer ngokumelene ne-inrush current.
(3) Ijubane lokuguga le-transformer insulation elibangelwa ukusetshenziswa okungalungile liyashesha.Isilinganiso sempilo yesevisi yabaguquli abajwayelekile yiminyaka eyi-17.8 kuphela, ephansi kakhulu kunempilo yesevisi elindelekile yeminyaka engu-35-40.
(4) I-voltage engaphezu kwamandla ebangelwa umbani.
(5) Ukugcwala.Ukulayisha ngokweqile kubhekisela ku-transformer esesimweni sokusebenza sokudlula amandla e-nameplate isikhathi eside.Ukulayisha ngokweqile kuvame ukuvela lapho isitshalo samandla siqhubeka nokwandisa kancane kancane umthwalo, idivayisi yokupholisa isebenza ngendlela engavamile, iphutha langaphakathi le-transformer, njll., futhi ekugcineni libangela ukuthi i-transformer ilayishe ngokweqile.Umphumela wokushisa ngokweqile uzoholela ekugugeni ngaphambi kwesikhathi kwe-insulation.Lapho ikhadibhodi le-insulating leminyaka ye-transformer, amandla ephepha azokwehla.Ngakho-ke, umthelela wamaphutha angaphandle ungaholela ekulimaleni kwe-insulation, okungase kubangele amaphutha.
(6) Ukudambisa: uma kunezikhukhula, ukuvuza kwepayipi, ukuvuza kwekhava yekhanda, ukungena kwamanzi ethangini likawoyela eduze komkhono noma izisekeli, futhi kukhona amanzi kuwoyela we-insulating, njll.
(7) Ukugcinwa ngendlela efanele akuzange kwenziwe.
