Hlaziya Isimiso Sokumelana Nezokwelashwa Kwe-Voltage Tester Fr

Izinto Ezisetshenziswa Kagesi Ezinamandla Kagesi Eziphezulu Kumelwe Zigcine I-Insulation Enhle Kakhulu Ngesikhathi Sokusebenza, Ngakho-ke Uchungechunge Lwezilingo Zokugqumisa Kufanele Kwenziwe Kusukela Ekuqaleni Kokukhiqizwa Kwezisetshenziswa.Lezi Zivivinyo Zihlanganisa: Ukuhlolwa Kwempahla Engavuthiwe Enqubweni Yokukhiqiza, Izivivinyo Ezimaphakathi Enqubweni Yokukhiqiza, Ukuhlolwa Kwekhwalithi Yomkhiqizo Kanye Nefekthri, Sebenzisa Ukuhlolwa Kokufakwa Esayithini, kanye Nokuhlolwa Kokuvimbela I-Insulation Ukuvikela Nokusebenza Ngesikhathi Sokusetshenziswa.Ubufakazi Bezinto Zokusebenza Kagesi Nezivivinyo Zokuvimbela Yizivivinyo Ezimbili Ezibaluleke Kakhulu.I-People's Republic of China Ikhodi Yemboni Yamandla Kagesi Kanye Nekhodi Yezwe: DL/T 596-1996 “Izinqubo Zokuhlola Zokuvimbela Izinto Zamandla” Kanye ne-GB 50150-91 “Izincazelo Zokuhlolwa Kokushintshwa Kwezisetshenziswa Kagesi” Cacisa Okuqukethwe Nokucaciswa Kwesivivinyo Ngasinye.

2. I-Insulation Preventive Experiment

Ukuhlolwa Kokuvinjelwa Kokufakwa Kwezinsimbi Zogesi Kuyisinyathelo Esibalulekile Sokuqinisekisa Ukusebenza Okuphephile Kwezisetshenziswa.Ngemuva kokuhlolwa, isimo sokufakwa kwe-insulation ye-Equipment singabanjwa, Ingozi Ye-Insulation Ingatholakala Ngesikhathi, Futhi Ukuvikelwa Kungasuswa.Uma Kunenkinga Engathi sína, Kudingekile Ukushintshwa Kwezinto Ezisetshenziswayo Ukuze Ugweme Ukulahlekelwa Okungenakulungiseka, Okufana Nokucisha Ugesi Noma Ukulimala Kwezisetshenziswa Okubangelwa Ukwehluleka Kokufakwa Kwamandla Ngesikhathi Sokusebenza.

Izivivinyo Zokuvimbela Ukufakwa Kwemishuqulo Zingahlukaniswa Izigaba Ezimbili: Eyodwa Isivivinyo Esingabhubhisi Noma Ukuhlolwa Kwesici Sokufakwa Kwamashuqa, Okubhekise Kumapharamitha Wezici Ezihlukahlukene Akalwa Ngamandla Amandla Aphansi Noma Ngezinye Izindlela Ezingeke Zilimaze I-Insulation, Kubandakanya Ukulinganisa Ukumelana Ne-Insulation, I-Dielectric Loss Tangent, Njll. Bese Unquma Ukuthi I-Insulation Inanoma Imaphi Amaphutha.Ukuhlola Kukhombisile Ukuthi Le Ndlela Iwusizo, Kodwa Ayinakusetshenziselwa Ukunquma Ngokwethembekile Amandla Kagesi Okufakwa Kwe-Insulation.Okunye Ukuvivinya Okulimazayo Noma Ukuhlolwa Kwengcindezi.I-Voltage Esetshenziswe Ekuhlolweni Iphakeme KuneVoltage Yokusebenza Yezisetshenziswa, Futhi Izimfuneko Zokuhlola I-Insulation Ziqine Kakhulu.Ikakhulukazi, Kukhona Ingozi Ekhudlwana Yokuveza Nokuhlanganisa Amaphutha, Nokuqinisekisa Ukuthi I-Insulation Inamandla Athile Kagesi, Okuhlanganisa I-DC Withstand Voltage, I-Communications Withstand Voltage, Njll. Ububi Be-Windstand Voltage Test Ukuthi Kuzodala Okunye Ukulimala Kwe-Insulation.

3. Ukuhlolwa Kokunikezwa Kwezisetshenziswa zikagesi

Ukuze Uhlangabezane Nezidingo Zobunjiniyela Bokufakwa Kagesi Nokuhlolwa Kokubuyisela Impahla Kagesi, Futhi Kuthuthukiswe Ukuphromothwa Nokusetshenziswa Kobuchwepheshe Obusha Bokuhlolwa Kokushintshwa Kwezisetshenziswa Kagesi, I-National Standard GB 50150-91 "Izicaciso Zokushintshwa Kwezisetshenziswa Kagesi" Iveza Ngokuqondile Okuqukethwe Imininingwane Yemilingo Ehlukahlukene.Ukwengeza Kwezinye Izivivinyo Zokuvimbela Ukufakwa Kwamanzi, Izivivinyo Zokushintshwa Kwezisetshenziswa Kagesi Zihlanganisa Okunye Ukuhlolwa Kwesici, Okufana Nokuhlolwa Kwe-Transformer DC kanye Nesilinganiso Sesilinganiso, I-Circuit Breaker Loop Resistance Experiments, Njll.

4. Isimiso Esiyisisekelo Sokuhlolwa Kokuvimbela Ukufakwa Kwamanzi

4.1 Ukuhlola Ukumelana Nokufakwa Kwe-Insulation Ukuhlola Ukumelana Nezinto Ezisetshenziswa Kagesi Yinto Esetshenziswa Kakhulu Futhi Elula Kakhulu Ekuhlolweni Kwezinto Ezisebenza Kagesi.Inani Lokumelana Ne-Insulation Lingabonisa Ngokuphumelelayo Ukushiyeka Kokufakwa Kwe-Insulation, Njengobuswakamo Baphelele, Ukungcola, Ukushisa Okubi Nokuguga.Ithuluzi Elisetshenziswa Kakhulu Lokuhlola Ukuphikiswa Kwe-Insulation I-Insulation Resistance Tester (I-Insulation Resistance Tester).

Ama-Insulation Resistance Testers (Isolation Resistance Testers) Ngokuvamile anezinhlobo ezifana ne-100 Volts, 250 Volts, 500 Volts, 1000 Volts, 2500 Volts, kanye nama-Volt angu-5000.I-Insulation Resistance Tester Kufanele Isetshenziswe Ngokuvumelana Ne-DL/T596 "Izinqubo Zokuhlola Zokuvimbela Izisetshenziswa Zamandla".

4.2 Ukuvuza Kwamanje Ukuhlolwa

I-Voltage Ye-General DC Insulation Resistance Tester Iphansi Kuno-2.5KV, Ephansi Kakhulu Kunogesi Osebenzayo Wezinto Ezithile Zikagesi.Uma Ucabanga ukuthi I-Voltage Yokulinganisa Ye-Insulation Resistance Tester Iphansi Kakhulu, Ungakala Ukuvuza Kwamanje Kwezisetshenziswa Kagesi Ngokungeza I-DC High Voltage.Izinto Ezisetshenziswa Kakhulu Zokukala Ukuvuza Kwamanje Kuhlanganisa Ama-High-Voltage Experimental Transformers Kanye nama-DC High-Voltage Generator.Lapho Izinto Ezisetshenziswayo Inezihibe, Ukuvuza Kwamanje Ngaphansi Kwe-Voltage Ephakeme Kukhulu Kakhulu Kunaleyo Ngaphansi Kwe-Voltage Ephansi, Okusho ukuthi, Ukumelana Nokufakwa Kwe-Insulation Ngaphansi Kwe-Voltage Ephakeme Kuncane Kakhulu Kunalokho Ngaphansi Kwe-Voltage Ephansi.

Awukho Umehluko Omukhulu Phakathi Kokuvuza Kwamanje Nokumelana Nokufakwa Komshini Wokukala Imishini Yokukala I-Voltage Tester, Kodwa Isilinganiso Samanje Sokuvuza Sinezimo Ezilandelayo:

(1) I-Voltage Yokuhlola Iphakeme Kakhulu Kunaleyo Ye-Insulation Resistance Tester.Ukushiyeka Kwe-Insulation ngokwayo Kuvezwa Kalula, Futhi Okunye Ukushiyeka Kokuhlangana Ngaphandle Kokungena Kungatholakala.

(2) Ukulinganisa Ukuxhumana Phakathi Kokuvuza Kwamanje Kanye Nogesi Osetshenziswayo Kusiza Ukuhlaziya Izinhlobo Zokukhubazeka Kokushisisa.

(3) I-Microampere Esetshenziselwa Isilinganiso Samanje Sokuvuza Inembe Kakhulu Kune-Insulation Resistance Tester.

4.3 I-DC Ibekezelela Ukuhlola Amandla Kagesi

Isivivinyo se-DC Withstand Voltage sinokuphezulu

Ukuxhumana Ukumelana Nokuhlolwa Kwe-Voltage Kwesinye isikhathi Kwenza Obunye Ubuthakathaka Ekushiseni Bugqame Kakhulu.Ngakho-ke, Kuyadingeka Ukwenza Izivivinyo Ngokumelana Nokufakwa Kwe-Insulation, Izinga Lokumuncwa, Ukuvuza Kwamanje Nokulahleka Kwe-Dielectric Ngaphambi Kokuhlolwa.Uma Umphumela Wokuhlola Ugculisa, Ukuhlolwa Kwezokuxhumana Okumelene Ne-Voltage Kungenziwa.Uma kungenjalo, Kufanele Kusetshenzwe Ngayo Ngokuhamba kwesikhathi, Futhi Ukuhlolwa Kokuxhumana Okumelene Ne-Voltage Kufanele Kwenziwe Ngemuva kokuthi Ithagethi Ngayinye Ifaneleka Ukugwema Ukulimala Okungadingekile Kwe-insulation.

4.5 Ukuhlolwa Kwe-Dielectric Loss Factor Tgδ

I-Dielectric Loss Factor Tgδ Ingenye Yezinjongo Eziyisisekelo Ezibonisa Ukusebenza Kokushisisa.I-Dielectric Loss Factor Tgδ Ibonisa Ipharamitha Yesici Sokulahlekelwa Kokufakwa Kwe-Insulation.Ingakwazi Ukuzitholela Ngokugcwele Ukushiswa Sekukonke Kwezisetshenziswa Kagesi Ezithintwa Ukumanzisa, Ukonakala, Nokuwohloka, Kanye Nokukhubazeka Kwasendaweni Kwezisetshenziswa Ezinosayizi Oncane.

Ukuqhathanisa I-Medical Withstand Voltage Tester Nokumelana Ne-insulation kanye Nokuhlolwa Kwamanje Kokuvuza, I-Dielectric Loss Factor Tgδ Inezinzuzo Ezibalulekile.Ayihlanganise lutho ne-Voltage Yokuhlola, Usayizi Wesampula Lokuhlola Kanye Nezinye Izinto, Futhi Kulula Kakhudlwana Ukuhlukanisa Ukushintsha Kokushisisa Kwezinto Ezisetshenziswa Kagesi.Ngakho-ke, I-Dielectric Loss Factor Tgδ Ingenye Yezivivinyo Ezibaluleke Kakhulu Zokuhlolwa Kokufakwa Kwezinto Ezisebenza Kagesi Ezinamandla Aphezulu.

I-Dielectric Loss Factor Tgδ Ingaba Lusizo Ukuthola Okulandelayo Okushiyeka Kwe-Insulation:

(1) Umswakama;(2) Ngena ku-Conductive Channel;(3) I-Insulation Iqukethe Amabhamuza Omoya Amahhala, Futhi I-Insulation Delaminates And Shells;(4) I-Insulation Ingcolile, Iwohlokile, Futhi Iyaguga.
