I-voltage ephephile yamanje nephephile
Ngokuvamile, umzimba womuntu ungakwazi ukuzwa inani lamanje lokukhuthazwa limayelana ne-1 mA.Lapho umzimba womuntu udlula i-5 ~ 20mA, imisipha izofinyela futhi inyakaze, ukuze umuntu angakwazi ukuhlukaniswa nocingo.Umkhiqizo we-electric shock current kanye nesikhathi esivunyelwe b...Funda kabanzi -
Isingeniso sezinzuzo kanye nokubi kokumelana nokuhlolwa kwamandla kagesi
Okubi Kokuhlola Okuqondile Kwamanje (DC) (1) Ngaphandle kwalapho kungekho amandla entweni elinganisiwe, i-voltage yokuhlola kufanele iqale “kuziro” futhi inyuke kancane ukuze igweme ukushaja kwamanje okukhulu.I-voltage eyengeziwe nayo iphansi.Uma i-chargency yokushaja inkulu kakhulu, izochaza...Funda kabanzi -
Izindaba ze-medical ukumelana ne-voltage instrument
Izinyathelo zokuphepha zokuhlola i-voltage tester Medical ukumelana ne-voltage test iyithuluzi elisetshenziselwa ukukala amandla okucindezela amasistimu ezokwelapha kanye nemishini yezokwelapha.Ingakwazi ukuhlola ngokunembile, ngokunembile, ngokushesha nangokuthembekile i-voltage yokuwohloka, ...Funda kabanzi -
Earth Resistance Test
Igama elithi "ukumelana nomhlabathi" igama elingachazwanga kahle.Kwamanye amazinga (njengamazinga okuphepha ezinto ezisetshenziswayo zasendlini), kubhekiselwa ekwaziseni phansi ngaphakathi kwempahla, kuyilapho kwamanye amazinga (njengakwikhodi yokuklama yaphansi), kubhekiselwe ekumelana ne ...Funda kabanzi -
Ukuhlolwa kwamanje kokuvuza
Ukuvuza kwamandla ezinto zasendlini kubhekiselwa kumandla avuzayo alinganiswa ngento esebenza ngogesi ngaphansi kwesenzo sikagesi.Kuzohlolwa.Umgomo wokuhlola uwukulingisa i-impedance yomzimba womuntu.Funda kabanzi -
Ukuhlolwa kwamandla e-Dielectric (ukumelana ne-voltage).
Ukuhlolwa kwamandla kagesi, okuvame ukwaziwa ngokuthi i-standard voltage test, isilinganiso sekhono le-insulation kagesi ukumelana nokuqhekeka ngaphansi kwesenzo sokugcwala ngokweqile.Futhi kuyindlela ethembekile yokuhlola ukuthi ingabe umkhiqizo uphephile yini ukusetshenziswa.Lapho...Funda kabanzi
