Izinto zokuvala umoya ukumelana Tester Futhi Ground Ukumelana Tester Te

Umehluko Kuzindlela Zokuhlola Phakathi Kokuvikela Ukumelana Nesivivinyo Kanye Ne-Ground Resistance Tester
(1) Indlela Yokuhlola Yesivikelo Sokuvikela Ukumelana
 
I-Insulation Resistance Tester Ukuhlola I-Degree Yokuvimbela Phakathi Kwezigaba, Izendlalelo Namaphoyinti Angathathi Hlangothi Wezintambo Nezintambo. Ukuphakama Kwenani Lokuhlolwa, Kungcono Ukusebenza Kokuvala Izinto. Ukumelana Nokuvala Izinto Kungalinganiswa Ngu-UMG2672 Megohmmeter Ye-elektroniki.
 
(2) Indlela Yokuhlola Yokuzama Ukumelana Nesisekelo
 
Isivivinyo Sokumelana Nesisekelo Yisisetshenziswa Samandla Esithola Ukuthi Ukumelana Okusisisekelo Kuyifanele Yini. Indlela Yokuhlola Yesisekelo Sokumelana Nesisekelo Ukuthi Izisetshenziswa Zikagesi Zixhunywe Kwamandla Afanayo NguMhlaba, Futhi Kungukusondelana Kwentambo Yokusabela Noma Umbani Oqhuba Phansi KuMhlaba. Inani Elilinganiswe Ngu-Grounding Resistance Tester Kuyindlela Elinganayo Yokuqinisekisa Ukuphepha Komuntu Siqu. Ungakhetha I-DER2571 Digital Grounding Resistance Tester Ekhiqizwe Ngu-WeiA Power.
 
Okwesine, Umehluko Wezimiso Phakathi Kokuvimbela Ukumelana Nomhloli Futhi Umhloli Wokumelana Nomhlabathi
 
(1) Umgomo Wokuvimbela Ukumelana Nokuvikela
 
Lapho Isivivinyo Sokumelana Nesivalo Sisetshenziswa Ukukala Ukumelana Nokuvimbela, I-DC Voltage U Isetshenzisiwe Ku-Insulation. Ngalesi sikhathi, Izinguquko Zamanje Ukuncishiswa Isikhathi, Futhi Ekugcineni Kuvame Inani Elizinzile.
 
Ngokuvamile, i-Current Of An Insulation Resistance Tester Is the Sum Of Capacitance Current, Absorption Current And Conduction Current. Inamandla Okwamanje Ic, Ijubane Layo Lokuncipha Lishesha kakhulu; Ukumuncwa Kwamanje Iaδc, Kubola Kancane Kancane Kunamandla Anamandla Okwamanje; Ukuqhutshwa Kwangaphakathi Inp, Kuvame Ukuzinza Esikhathini Esifushane.
 
Ngesikhathi Sokuhlolwa Usebenzisa Isivikelo Sokumelana Nokumelana, Uma Ukufakwa Kokuvikela Kungabi Nomswakama Futhi Ubuso Buhlanzekile, Izakhi Zesikhashana Ezidlulayo Ic Futhi Iaδc Izobola Ngokushesha Kuzero, Ishiya Kuphela Ukuqhutshwa Okuncane Okwamanje Ukudlula, Ngoba Ukumelana Nokuvala Izinto Kuphambene Ngokuphambene Elinganayo Ukuze Okwamanje Yijikeleza, I-Insulation Resistance Izovuka Ngokushesha Futhi Iqinise Ngenani Elikhulu. Ngakolunye uhlangothi, Uma Ukufakwa Kwezinto Zokushisa Kumanzi, I-Conduction yamanje Ikhuphuka Ngokuphawuleka, Noma Ishesha Kakhulu Kunenani Lokuqala Le-Absorption yamanje Iaδc, Ingxenye Yesikhashana Esidlulile Iyancipha Ngokuphawulekayo, Futhi Inani Lokumelana Nokuvikela Liphansi Kakhulu, Futhi Liguquka Kakhulu Ngokuhamba kwesikhathi. Incane.
 
Ngakho-ke, Esivivinyweni Sokuhlolwa Kwe-Insulation Resistance Tester, Okuqukethwe Komswakama Kwe-Insulation Kuvame Ukwahlulelwa Isilinganiselo Sokumuncwa. Lapho isilinganiso se-Absorption Isikhulu Kakhulu Kune-1.3, Sikhombisa Ukuthi Ukufakwa Kokuvikela Kuhle kakhulu. Uma i-Absorption Ratio Isondele Ku-1, Kubonisa Ukuthi Ukufakwa Kwezinto Kumanzi.
 
(2) Isimiso Sokuzama Ukumelana Nesisekelo
 
Isisekelo Sokumelana Nesisekelo Sibizwa nangokuthi Isisekelo Sokumelana Sokulinganisa Insimbi, Isisekelo Esiqinile. Umgomo Wokuhlola Wokuhlolwa Kwe-Ground Resistance Ukuthola I-Ground Resistance Value "Rx" Ngokusebenzisa i-AC Constant yamanje "I" Phakathi Kwe-Ground Electrode "E" Kanye ne-Power Supply Electrode "H (C)" Ye-Object Under Test, Futhi Isisekelo Siyatholakala Umehluko Wesikhundla “V” Phakathi Kwe-Electrode “E” Kanye Ne-electrode Yokulinganisa “S (P)”.
