Indlela yokuhlola ukusebenza kwephampu kaphethiloli
Amanye amaphutha aqinile (njengokungasebenzi, njll.) ephampu kaphethiloli yemoto kulula ukuwahlulela, kodwa amanye amaphutha athambile ngezikhathi ezithile kunzima ukuwahlulela. Kulokhu, ukusebenza kwephampu kaphethiloli kungahlulelwa ngendlela yokuthola amandla okusebenza ephampu kaphethiloli nge-multimeter yedijithali yemoto. Indlela ethile yile elandelayo.
(1) Faka i-multimeter yedijithali yemoto kubhulokhi yamanje, cindezela inkinobho yokusebenza (SELECT) ukuze ulungise ibhulokhi yamanje eqondile (DC), bese uxhuma amapeni amabili okuhlola ngokulandelana emgqeni wokuxhuma wephampu kaphethiloli ozohlolwa.
(2) Qala injini, uma iphampu kaphethiloli isebenza, cindezela inkinobho yokurekhoda enamandla (MAX/MIN) ye-multimeter yedijithali yemoto ukuze urekhode ngokuzenzakalelayo ugesi ophezulu nowobuncane lapho iphampu kaphethiloli isebenza. Ngokuqhathanisa idatha etholakele nenani elijwayelekile, imbangela yokwehluleka ingatholakala.
Izinyathelo Zokuphepha Zokuthola Ukwehluleka Kwephampu Kaphethiloli Ukusakazwa Kokuhlela
1. Iphampu kaphethiloli endala
Uma kulungiswa amaphampu kaphethiloli ezimotweni ezisetshenziswe isikhathi eside, lawa maphampu kaphethiloli akufanele ahlolwe ngendlela eyomile. Ngoba uma iphampu kaphethiloli isuswa, kukhona uphethiloli osele ekhasethini lephampu. Ngesikhathi sokuhlolwa kokuvula amandla, uma ibhulashi kanye ne-commutator kungaxhumani kahle, inhlansi izothungela uphethiloli ekhasethini lephampu futhi ibangele ukuqhuma. Imiphumela iyingozi kakhulu.
2. Iphampu entsha kaphethiloli
Iphampu kaphethiloli esanda kufakwa esikhundleni akumele ihlolwe ngokomile. Ngenxa yokuthi injini yephampu kaphethiloli ivaliwe ekhasethini lephampu, ukushisa okukhiqizwa amandla ngesikhathi sokuhlolwa okomile akukwazi ukunyamalala. Uma i-armature isishisiwe kakhulu, imoto izoshiswa, ngakho-ke iphampu kaphethiloli kumele ifakwe kuphethiloli ukuze kuhlolwe.
3. Ezinye izici
Ngemva kokuba ipompo kaphethiloli iphumile ethangini likaphethiloli, ipompo kaphethiloli kufanele isulwe kahle ngesikhathi, futhi kufanele kugwenywe izinhlansi eduze kwayo, futhi kufanele kulandelwe isimiso sokuphepha "socingo kuqala, bese kuvulwa amandla".
