Insulation Resistance Tester Yakakodzera Kuyera Kukosha Kwekupokana Kwezvinhu Zvakasiyana Zvokumisa uye Kupokana kweMagetsi, Mota, Matambo uye Zvishandiso zveMagetsi, kuve nechokwadi chekuti Zvishandiso izvi, Zvishandiso zveMagetsi uye Mitsetse inoshanda mune Zvakajairwa Mamiriro Ekudzivirira Kutya Kwemagetsi, uye Equipment. Kukuvadza.
Matambudziko Akajairika EIsulation Resistance Tester ndeaya anotevera:
1. Pakuyera Capacitive Load Resistance, Chii Chiri Hukama Pakati Pekubuda Mupfupi-Denderedzwa Yazvino YeInsulation Resistance Tester Uye Iyo Yakayerwa Dhata, Uye Sei?
Saizi Yeiyo Inobuda Ipfupi-Circuit Yazvino YeInsulation Resistance Tester Inogona Kuratidza Saizi Yemukati Kupokana Kweiyo Yakakwira-Voltage Source Mukati Megger.
Mazhinji Insulation Miedzo Target Capacitive Loads, Senge Akareba Cables, Motors Ine Akawanda Windings, uye Transformers.Naizvozvo, Kana Iyo Yakayerwa Target Iine Kugona, Pakutanga Kweiyo Yekuedza Maitiro, Iyo Yepamusoro-Voltage Sosi muInsulation Resistance Tester Inofanirwa Kuchaja Iyo Capacitor Kuburikidza Nekupokana Kwayo Kwemukati, uye Zvishoma Nezvishoma Kuchaja Voltage kune Yekuwedzera Yakakwira-Voltage Kubuda kweiyo. Insulation Resistance Tester..Kana Iyo Capacitance Value Yeiyo Yakayerwa Target Yakakura, kana iyo Yemukati Resistance yeHigh-Voltage Source Yakakura, Iyo yekuchaja Maitiro Inotora Nguva Yakareba.
Kureba Kwayo Kunogona Kutemwa Nechigadzirwa cheR Inner uye C Mutoro (Unit: Chechipiri), Kureva, T = R Inner * C Mutoro.
Naizvozvo, Panguva Yekuedzwa, Zvinodikanwa Kuchaja Yakadaro Capacitive Mutoro Kuiyo Yekuyedza Voltage, Uye Kuchaja Yekumhanyisa DV/Dt Yakaenzana Neyero Yekuchaja Yazvino I kune Kutakura Capacitance C. Kureva, DV/Dt= I/C.
Naizvozvo, Iyo Idiki Iyo Yemukati Kupokana Uye Yakakura Iyo Kuchaja Yazvino, Iyo Inokurumidza Mibairo Yekuedza Ichagadzikana.
2. Chii Chiri Basa re "G" Divi reChitarisiko?Mune Yakakwira-Voltage Uye Yakakwira-Kupokana Yekuyedza Nzvimbo, Sei Zvichidikanwa Kubatanidza Iyo "G" Terminal Kunze?
Iyo "G" Kupera Kwepamusoro Inzvimbo Inodzivirira.Basa Reiyo Shielding Terminal Kubvisa Kufurira Kwehunyoro uye Tsvina Munzvimbo Yekuyedza Pamibairo yekuyera.Iyo Yekunze "G" Terminal Bypassing Iyo Leakage Yazvino Yechigadzirwa Chakaedzwa, Kuti Iyo Leakage Yazvino Isapfuura Neyekunze Yekuyedza dunhu, uye Inobvisa Iko Kukanganisa Kunokonzerwa Nekudonha Kwezvino.Iyo G Terminal Inoshandiswa Pakuyedza Kupokana Kwakanyanya.
Kazhinji Kutaura, Iyo G Terminal Inogona Kutariswa Yepamusoro Kupfuura 10G.Nekudaro, Iyi Resistance Range haina chokwadi.Kana Yakachena uye Yaoma uye Ivhu reChiyedzo Chinhu Chidiki, Inogona Kugadzikana Pasina Kuyera 500G Kumagumo eG.Munzvimbo Dzakanyorova Uye Netsvina, Yakaderera Kuramba Kukosha Inodawo Iyo G End.Kunyanya, Kana Iwe Ukaona Kuti Mhedzisiro Yakaoma Kudzikamisa Paunenge Uchiyera Kukwirisa Kupokana, Unogona Kufunga Kushandisa Iyo G Terminal.Ziva zvakare kuti Iyo Shielding Terminal G haina kubatana neShielding Layer, asi kune Insulator iri pakati peL neE kana kune Multi-Straded Waya, kwete kune mamwe mawaya ari Kuedzwa.
3. Sei Zvisiri Kungodiwa Kuyera Kwakachena Resistance Value Pakuyera Insulation, Asi Zvakare Kuyera Iyo Absorption Ratio Uye Polarization Index.Chii Chinokosha?
PI Ndiyo Polarization Index, Iyo Inoreva Kuenzanisa Pakati Pekupokana Kwekudzivirira Kwemaminetsi gumi uye Kupokana Kwemaminiti 1 Panguva Yekuedzwa kweInsulation;
DAR Ndiyo Dielectric Absorption Ratio, Iyo Inoreva Kuenzanisa Pakati Pekupokana kweInsulation Kweminiti 1 uye Kupokana kweInsulation kwe15s Munguva Yekuyedza Insulation;
Muyedzo yeInsulation, iyo Insulation Resistance Value pane imwe nguva haigone kuratidza zvizere Basa reInsulation yeSampuri Yekuyedza.Izvi Zvinokonzerwa Nezvikonzero Zviviri Zvinotevera.Kune rumwe rutivi, iyo Insulation Resistance yeRimwechete Basa reInsulation Material Idiki Kana Iro Ihombe., The Insulation Resistance Inoratidzika Kana Iro Iri Idiki.Kune rimwe divi, Iyo Insulating Material ine Maitiro eiyo Absorption Ratio uye iyo Polarization Maitirwo ekuchaja Mushure mekunge Iyo Yakakwira Voltage Yaiswa.Naizvozvo, Iyo Simba Sisitimu Inoda kuyerwa kweAbsorption Ratio-iyo Ratio yeR60s uye R15s, uye iyo Polarization Index-iyo Ratio yeR10min uye R1min muyedzo yeInsulation yeMain Transformers, Cables, Motors uye Zvimwe Zvizhinji Zviitiko, uye shandisa Izvi. Dhata Yekuona Iyo Insulation Yakanaka Kana Yakashata.
4. Sei Iyo Electronic Insulation Resistance Tester Ichigona Kugadzira Yakakwira DC Yakakwira Voltage Kana Inofambiswa Nemabhatiri akati wandei?Izvi zvinoenderana neSimboti yeDC Shanduko.Iyo Yepasi Power Supply Voltage Inosimudzwa Kukwira Kubuda DC Voltage kuburikidza neBoost Circuit Processing.Iyo Yakakwira Voltage Yakagadzirwa Yakakwira Asi Simba Rokubuda Idiki (Rishoma Simba Uye Diki Yazvino).
Cherechedza: Kunyange Kana Simba Rakanyanya Kuduku, Hazvikurudzirwi Kubata Pachako Test Probe, Pachave Nekunzwa Kunzwa.
