I-Insulation Resistance Tester Ifanele Ukukala Inani Lokumelana Lezinto Ezihlukahlukene Zokugqumisa kanye Nokumelana Nokufakwa Kwe-Insulation Kwama-Transformers, Ama-Motor, Amakhebula Nezinto Zokusebenza Kagesi, Ukuqinisekisa Ukuthi Lezi Zisetshenziswa, Izinto zikagesi kanye Nolayini Basebenza Ezimeni Ezijwayelekile Ukugwema Ukushaqeka Kagesi, Imishini Kagesi kanye Nezinsimbi. Umonakalo.
Izinkinga Ezivamile Ze-Insulation Resistance Tester Zimi kanje:
1. Uma Kukalwa Ukumelana Nomthwalo Onamandla, Buyini Ubudlelwano Phakathi Kwesekethe Esifushane Sokukhiphayo Kwamanje Komhloli Wokumelana Nokufakwa Kwe-Insulation kanye Nedatha Ekaliwe, Futhi Kungani?
Usayizi Wokukhishwa Kwesekethe Emfishane Yamanje Yesihloli Sokumelana Nokufakwa Kwangaphakathi Ungabonisa Usayizi Wokumelana Kwangaphakathi Komthombo We-Voltge Ephezulu Ngaphakathi Kwe-Megger.
Izivivinyo Eziningi Zokugqumisa Ziqondise Imithwalo Enamandla, Njengezintambo Ezinde, Izimoto Ezinama-Windings Engeziwe, nama-Transformer.Ngakho-ke, Uma Ithagethi Elinganisiwe Inamandla, Ekuqaleni Kwenqubo Yokuhlola, Umthombo We-Voltge Ephakeme Ku-Insulation Resistance Tester Kufanele Ushaje I-Capacitor Ngokumelana Kwayo Kwangaphakathi, Futhi Kancane Kancane Ushaje I-Voltage Kokuphuma Kwe-Voltage Eyengeziwe Ye- I-Insulation Resistance Tester..Uma I-Capacitance Value Yethagethi Elinganisiwe Inkulu, Noma Ukumelana Kwangaphakathi Komthombo We-Voltge Ephakeme Kukhulu, Inqubo Yokushaja Izothatha Isikhathi Eside.
Ubude Bayo bunganqunywa Ngomkhiqizo Womthwalo We-R Wangaphakathi No-C (Iyunithi: Okwesibili), Okungukuthi, T=R I-Inner*C Yomthwalo.
Ngakho-ke, Ngesikhathi Sokuhlolwa, Kudingekile Ukushaja Umthwalo Onjalo Onamandla Kugesi Wokuhlola, Futhi Isivinini Sokushaja i-DV/Dt Silingana Nesilinganiso Sokushaja Kwamanje I Kumandla Womthwalo C. Okungukuthi, DV/Dt= I/C.
Ngakho-ke, Okuncane Ukumelana Kwangaphakathi Futhi Okukhulu Ukushaja Kwamanje, Okusheshayo Imiphumela Yokuhlola Izozinza.
2. Uyini Umsebenzi Wohlangothi Lwe-“G” Lokubukeka?Endaweni Yokuhlola I-High-Voltage Futhi Emelana Kakhulu, Kungani Kudingeka Ukuxhuma Itheminali “G” Ngaphandle?
Ukuphela "G" Komphezulu Kuyitheminali Evikelayo.Umsebenzi Wetheminali Yokuvikela Ukususa Umthelela Womswakama Nokungcola Endaweni Yokuhlola Emiphumeleni Yokulinganisa.Itheminali ethi “G” Yangaphandle Idlula Ukuvuza Kwamanje Komkhiqizo Ohloliwe, Ukuze Ukuvuza Kwamanje Kungadluli Kumjikelezo Wokuhlola Wangaphandle, Futhi Kuqede Iphutha Elidalwe Ukuvuza Kwamanje.Itheminali ye-G Isetshenziswa Lapho Uhlola Ukumelana Okuphezulu.
Ngokuvamile, Itheminali ye-G Ingacatshangelwa Ngaphezulu Kwe-10G.Nokho, Leli Range Lokuphikisa Aliqinisekile.Uma Ihlanzekile Futhi Yomile Futhi Ivolumu Yento Yokuhlola Incane, Ingakwazi Ukuzinza Ngaphandle Kokulinganisa I-500G Ekugcineni kwe-G.Ezindaweni Ezinomswakama Nezingcolile, Inani Lokumelana Eliphansi Lidinga Futhi Ukuphela Kwe-G.Ngokuqondile, Uma Uthola Ukuthi Imiphumela Inzima Ukuzinza Lapho Ukala Ukumelana Okuphakeme, Ungacabanga Ukusebenzisa I-G Terminal.Futhi Yazi Ukuthi Itheminali Eyisivikelo G Ayixhumene Nesendlalelo Esivikelayo, Kodwa Kusivikelo Phakathi kuka-L no-E Noma Intambo Eminyene, Hhayi Kwezinye Izintambo Ezingaphansi Kokuhlolwa.
3. Kungani Kungadingeki Kuphela Ukukala Inani Elimsulwa Lokumelana Lapho Kukalwa Ukufakwa Kwamanzi, Kodwa Futhi Ukukala Isilinganiso Sokumuncwa kanye Nenkomba Ye-polarization.Liyini Iphuzu?
I-PI Yinkomba Ye-Polarization, Ebhekisela Ekuqhathanisweni Phakathi Kokumelana Nokufakwa Kwama-Insulation Kwemizuzu eyi-10 kanye Nokumelana Nokufakwa Kwe-Insulation Kweminithi elingu-1 Ngesikhathi Sokuhlolwa Kokufakwa Kwe-Insulation;
I-DAR Isilinganiso Sokumuncwa Kwe-Dielectric, Okubhekisela Ekuqhathaniseni Phakathi Kokumelana Nokufakwa Kwe-Insulation Kweminithi elingu-1 kanye Nokumelana Nokufakwa Kwe-Insulation Kwama-15s Phakathi Nokuhlolwa Kokufakwa Kwe-Insulation;
Esivivinyweni Sokugqumisa, Inani Lokumelana Nokufakwa Kwamanzi Esikhathini Esithile Alikwazi Ukubonisa Ngokugcwele Umsebenzi Wokushisisa Wesampula Lokuhlola.Lokhu Kubangelwa Izizathu Ezimbili Ezilandelayo.Ngakolunye uhlangothi, Ukumelana Nokufakwa Kwe-Insulation Komsebenzi ofanayo Wezinto Zokufaka I-Insulation Kuncane Uma Ivolumu Inkulu., I-Insulation Resistance Ivela Lapho Ivolumu Incane.Ngakolunye uhlangothi, I-Insulating Material Inenqubo Yesilinganiso Sokumuncwa kanye Nenqubo Ye-Polarization Yeshaja Ngemva Kokusetshenziswa Kwe-Voltage Ephezulu.Ngakho-ke, Isistimu Yamandla Idinga Ukulinganiswa Kwesilinganiso Sokumuncwa-Isilinganiso Sama-R60 No-R15, Nenkomba Ye-polarization-I-Ratio Ka-R10min kanye No-R1min Ekuhlolweni Kwe-Insulation Yama-Main Transformers, Amakhebula, Izinjini Nezinye Izikhathi Eziningi, Futhi Sebenzisa Lokhu. Idatha yokunquma ukuthi i-insulation iyinhle noma imbi.
4. Kungani I-Electronic Insulation Resistance Tester Ikhiqiza I-DC High Voltage Ephakeme Uma Inikwa Amandla Amabhethri Amaningi?Lokhu Kusekelwe Kumgomo Wokuguqulwa Kwe-DC.I-Lower Power Supply Voltage Inyuselwa Ekuphumeni Okuphezulu I-DC Voltage Ngokusebenzisa I-Boost Circuit Processing.I-Voltage Ephakeme Ekhiqiziwe Iphakeme Kodwa Amandla Okukhiphayo Mancane (Amandla Aphansi Futhi Mancane Amanje).
Qaphela: Noma Amandla Emancane Kakhulu, Akunconyiwe Ukuthi Uzithinte Mathupha I-Test Probe, Kusazoba Nomuzwa Olumayo.
