I-cable intermediate joint iyithuluzi elixhuma ikhebula nebhokisi lokuhlangana, futhi lisetshenziselwa ukuxhuma umgogodla wekhebula noma i-sheath, i-insulation kanye nesheath komunye nomunye.Kuzinhlelo zokusebenza zesistimu yamandla, inani loxhumo oluphakathi nendawo liphezulu.Amalungu avamile aphakathi nendawo anohlobo oluqondile (oluvame ukwaziwa ngokuthi "i-straight-through") kanye nohlobo lokugoba.
Izici zohlobo oluqondile yilezi:
(1) Isakhiwo esilula, usayizi omncane nesisindo esincane;
(2) Ukwakhiwa kulula, futhi kungenziwa ngaphandle kokuhlubula umgodla wangaphandle wekhebula ngesikhathi sokufakwa;
(3) Intengo ishibhile, kodwa ukulahlekelwa komugqa ngemva kokubeka kukhulu.
Izici zohlobo olugobile yilezi:
(1) Isakhiwo siyinkimbinkimbi kakhulu;
(2) Ukulahlekelwa kolayini okukhiqizwa ngemva kokubekwa kuncane kunohlobo oluqondile;
(3) Ukwakhiwa kuyinkinga kancane;
(4) Intengo iphakeme kancane.
Kubunjiniyela obusebenzayo, indlela yokumelana ne-DC ngokuvamile isetshenziswa ukuthola ukusebenza kwe- through.Umgomo wendlela yokumelana ne-DC ukuthi lapho i-voltage ye-DC isetshenziswa kuma-electrode amabili e- through, inani lokumelana lihambisana ngokuphambene nesikwele se-voltage esetshenzisiwe.
Ngakho-ke, inqobo nje uma usayizi wokumelana ne-DC ulinganiswa, ukuqhutshwa kwe-pass-pass kungaziwa.Izindlela zokulinganisa ukumelana ne-DC zihlukaniswe izigaba ezimbili: indlela eqondile kanye nendlela engaqondile:
Indlela eqondile ukukala ngokuqondile ukwehla kwe-voltage ye-DC phakathi kwama-electrode amabili nge-multimeter ukuze kutholakale ubuhle nobubi be-straight-through.
Indlela engaqondile ukwahlulela ukuthi ifanelekile yini noma cha ngokulinganisa amandla ashintshanayo phakathi kwama-electrode amabili, ebizwa ngokuthi indlela ye-AC impedance noma indlela yokuhlola amandla kagesi ukumelana ne-AC.Indlela yokuhlola i-voltage imvamisa yamandla ingenye yezindlela ezijwayelekile nezisebenzayo zokwahlulela ukuthi ingxenye ethile kakhondakta ifanelekile noma cha..
Uma i-voltage yefrikhwensi yamandla yenani elishiwo (imvamisa engu-50hz) isetshenziswa kuzo zombili iziphetho zekhondatha ehloliwe, bheka ukuthi umkhiqizo ohloliwe unento ehlukile yini.Akusebenzi kulesi sigaba socingo.
