Umehluko ezindleleni zokuhlola phakathi kokuhlolisisa ukumelana nokungamelana nomhlaba
(1) Indlela yokuhlola yomhloli wokumelana wokufakelwa
Umhloli wokumelana wokufakelwa ukuvivinya izinga lokufakelwa phakathi kwezigaba, izingqimba namaphuzu angathathi hlazo izintambo nezintambo. Inani lokuhlola, elingcono ukusebenza kokufakwa. Ukumelana nokufakelwa kungalinganiswa nge-Electronic Megohmmeter.
(2) Indlela yokuhlola yomhloli wokumelana nokubekeka phansi
Umhloli wokumelana nesendlalelo yimishini yamandla ethola ukuthi ukumelana okuyisisekelo kufanelekile yini. Indlela yokuhlola yomhloli wokumelana onesisekelo ukuthi imishini kagesi ixhumeke emandleni afanayo aphakathi komhlaba, futhi kungukusondelana kocingo lokuphendula noma umlobi phansi komqhubi phansi emhlabeni. Inani elinganiselwa ngabe umhloli wokumelana esitebalayo liyisilinganiso esisebenzayo sokuqinisekisa ukuphepha komuntu siqu. Ungakhetha umhloli wokumelana wedijithali we-der2571 wedijithali okhiqizwe amandla we-weia.
Okwesine, umehluko wemigomo phakathi kokuhlolisisa ukumelana nokuqina komsizi
(1) Umgomo wokuhlolisisa ukumelana kokufakelwa
Lapho kusetshenziswa umhloli wokumelana nokufakelwa ukukala ukumelana kokufakelwa, i-DC Voltage U usetshenziswa ekufakweni. Ngalesi sikhathi, ushintsho lwamanje lwe-at hatstenuation ngokuhamba kwesikhathi, futhi ekugcineni luvame ukuvelela inani elizinzile.
Ngokuvamile, okukhona kwe-inhloso yokumelana kokufakelwa yisamba se-capcacitance yamanje, ukumuncwa kwamanje kanye nokwenziwa kwamanje. I-capacitive yamanje, ijubane layo le-attenunuation lishesha kakhulu; Ukutholwa kwamanje i-IAΔC, ibola kancane kancane kune-capacive yamanje; I-Conction I-INP yamanje, ivame ukuzinza ngesikhathi esifushane.
Ngesikhathi sokuhlolwa usebenzisa umhloli wokumelana wokufakelwa, uma ukufakwa kungabi mnyama futhi ingaphezulu lihlanzekile, izingxenye zamanje ze-IC kanye ne-IACH zizokubola ngokushesha ku-zero, ngoba ukumelana kwamanje kwe-insuration Ngokulingana nokujikeleza kwamanje, ukumelana kokufakelwa kuzovuka ngokushesha futhi uzinze ngenani elikhulu. Ngakolunye uhlangothi, uma ukufakwa kungumanzi, ukufakwa kwamanje kwandiswa kakhulu, ngisho nokushesha kunenani lokuqala le-Ivac yamanje, futhi inani lokumelana lokufakelwa liphansi kakhulu, futhi lishintsha kakhulu ngokuhamba kwesikhathi. Micro.
Ngakho-ke, ekuhlolweni komhloli wokumelana nokufakelwa, okuqukethwe umswakama wokufakelwa kuvame ukwahlulelwa yisilinganiso sokumuncwa. Lapho isilinganiso sokufaka umhlobiso sikhulu kune-1.3, kukhombisa ukuthi ukufakwa kuhamba kahle. Uma isilinganiso sokumuncwa siseduze no-1, kukhombisa ukuthi ukufakwa kungumanzi.
(2) Umgomo wokuhlolisisa ukumelana nokumelana
Umhloli wokumelana nokumelana nawo ubizwa nangokuthi ithuluzi lokulinganisa lokumelana, iShaker eyisansi. Umgomo wokuhlola wokuhlolwa kokumelana nomhlabathi ukuthola inani lokumelana nomhlabathi "RX" nge-AC njalo yamanje "I" phakathi kwe-Electrode ye-Ground Electrode "e" kanye ne-Power Vall Electrode "kanye ne-Power Verlectrode" Futhi isisekelo sitholakala umehluko wesikhundla "v" phakathi kwe-electrode "e" kanye ne-s (P) ".
