Kungani Kufanele Usebenzise Isiphetho sika-“G” Sangaphandle Ukuze Ulinganise Ukuphikiswa Okuphezulu
Itheminali “G” (Itheminali Yokuvikela) Yengaphandle, Umsebenzi Wayo Ukususa Ithonya Lokuswakama Nokungcola Endaweni Yokuhlola Emiphumeleni Yokulinganisa.Lapho Ukala Ukumelana Okuphakeme, Uma Uthola Ukuthi Imiphumela Inzima Ukuzinzisa, Ungacabanga Ukusebenzisa I-G Terminal Ukuqeda Amaphutha.
03
Ukwengeza Ekulinganiseni Ukumelana, Kungani Kufanele Silinganise I-Absorption Ratio kanye Nenkomba Ye-Polarization?
Esivivinyweni Sokugquma, Inani Lokumelana Nokufakwa Kwamanzi Esikhathini Esithile Alikwazi Ukubonisa Ngokugcwele Ubuhle Nebubi Bomsebenzi Wokugqumisa Wesampula Lokuhlola.Ngakolunye uhlangothi, ngenxa ye-Insulation Material Yomsebenzi ofanayo, Ukuphikiswa Kwe-Insulation Kuvela Lapho Ivolumu Inkulu, Futhi Ukumelana Ne-Insulation Kuvela Lapho Ivolumu Incane.Okukhulu.Ngakolunye uhlangothi, I-Insulating Material Inenqubo Ye-Charge Absorption Ratio (DAR) kanye Nenqubo Ye-Polarization (PI) Ngemva Kokufaka I-Voltage Ephezulu.
04
Kungani I-Electronic Insulation Resistance Tester Ikhiqiza I-DC High Voltage Ephakeme
Ngokuvumelana Nomgomo Wokuguqulwa Kwe-DC, Isihloli Sokumelana Ne-Electronic Insulation Esinikezwa Amabhethri Amaningana Sicutshungulwa Yisekethe Yokulekelela.I-Lower Power Supply Voltage Izokwenyuswa Ifinyelele Ekuphumeni Okuphezulu I-DC Voltage.I-Voltage Ephakeme Ekhiqiziwe Iphakeme Kodwa Amandla Okukhiphayo Aphansi.
Izinyathelo Zokuqaphela Ukusetshenziswa Kwe-Insulation Resistance Tester
1. Ngaphambi Kokulinganisa, Yenza Ukuhlola Kwesekethe Evulekile Kanye Neseyingi Efushane Kumhloli Wokumelana Nokufakwa Kwe-Insulation Ukuhlola ukuthi Umhloli We-Insulation Resistance Tester Ujwayelekile.Ukusebenza Okuthize Kuwukuthi: Vula Izintambo Ezimbili Ezixhumayo, Isikhombi Sesibambi Sokujikijela Kufanele Sikhombe Ku-Infinity, Bese Sifinyeza Izintambo Ezimbili Ezixhumayo, Isikhombi Kufanele Sikhombe Kuziro.
2. Idivayisi Engaphansi Kokuhlolwa Kufanele Inqanyulwe Kweminye Imithombo Yamandla.Ngemva kokuthi Ukulinganisa Sekuqediwe, Idivayisi Engaphansi Kokuhlolwa Kufanele Ikhishwe Ngokugcwele (Cishe 2~3 Amaminithi) Ukuze Kuvikelwe Izisetshenziswa Nokuphepha Komuntu Siqu.
3. I-Insulation Resistance Tester kanye Nedivayisi Engaphansi Kokuhlolwa Kufanele Ihlukaniswe Futhi Ixhunywe Ngokuhlukana Ngocingo Olulodwa, Futhi Ubuso Besekethe Kufanele Kugcinwe Kuhlanzekile Futhi Komile Ukuze Kugwenywe Amaphutha Abangelwa Ukufakwa Okubi Phakathi Kwezintambo.
4. Ngesikhathi Sokuhlolwa Okuzamazamayo, Beka I-Insulation Resistance Tester Endaweni Evundlile, Futhi Akukho Circuit Emfushane Phakathi Kwezinkinobho Zetheminali Evunyelwe Uma Isibambo Sigingqika.Lapho Uhlola Ama-Capacitor Namakhebula, Kuyadingeka Ukunqamula Intambo Lapho Isibambo Se-Crank Sigingqika, Ngaphandle kwalokho Ukushaja Okuhlehlayo Kuzolimaza Isihloli Sokumelana Ne-Insulation.
5. Lapho Ushwiba Isibambo, Kufanele Sihambe Kancane Futhi Sisheshe, Futhi Sisheshise Ngokulinganayo Sifike ku-120r/min, Futhi Unake Ukuze Uvimbele Ukushaqeka Kagesi.Ngesikhathi Senqubo Yokushwibeka, Lapho Isikhombi Sesifinyelele Kuziro, Asisakwazi Ukuqhubeka Sishwiba Ukuze Sivimbele Ukushisisa Nokulimala Kwekhoyili Ewashini.
6. Ukuze Ugweme Ukumelana Nokuvuza Kwedivayisi Ngaphansi Kokuhlolwa, Lapho Usebenzisa Isihloli Sokumelana Nokufakwa Kwe-Insulation, Isendlalelo Esimaphakathi Sedivayisi Esingaphansi Kokuhlolwa (Okufana Nokufakwa Kwangaphakathi Kwangaphakathi Phakathi Kwe-Cable Shell Core) Kufanele Sixhunywe Kwindandatho Yokuzivikela.
7. Isihloli Esifanelekile Sokumelana Nokufakwa Kwamanzi Kufanele Sikhethwe Kuye Ngezinga Lamandla Kagesi Wezinto Ezisetshenziswayo Ezivivinywayo.Ngokuvamile, Okokusebenza Okune-Voltage Ekalwe Ngaphansi Kwama-Volt angu-500, Khetha I-Insulation Resistance Tester Yama-Volt angu-500 Noma Ama-Volt angu-1000;Okokusebenza Okune-Voltage Elinganiselwe Yama-Volt angu-500 Nangaphezulu, Khetha I-Insulation Resistance Tester Yama-Volts angu-1000 kuya kwangu-2500.Ekukhetheni Isikali Sobubanzi, Kufanele Kuqashelwe Ukungenzi Isikali Sokulinganisa Seqe Ngokweqile Inani Lokumelana Nokufakwa Kwezinto Ezingaphansi Kokuhlolwa Ukuze Kugwenywe Amaphutha Amakhulu Ekufundweni.
8. Vimbela Ukusetshenziswa Kwabahloli Be-Insulation Resistance Ukulinganisa Isimo Sezulu Sombani Noma Izinto Eziseduzane Nama-Conductor Anamandla Aphezulu.
