INDLELA YOKUSEBENZISA I-ZINC OXIDE ARRESTER TESTER?

Xa kusetyenziswa izithinteli ze-zinc oxide ixesha elide, ukuguga kwe-insulation kuhlala kwenzeka. Ingabonakala iqhelekile ngaphandle, kodwa ingaphakathi ayifanelekanga ukuqhubeka nokusebenza. Ke ngoko, kuyimfuneko ukujonga ukusebenza kwe-insulation ye-zinc oxide arresters ngexesha. Kusetyenziswa i-zinc oxide arrester tester, ngoko ke ungayisebenzisa njani i-zinc oxide arrester tester?

I-Zinc oxide arrester field tester sisixhobo esikhethekileyo sokuvavanya iimpawu zombane ze-zinc oxide arresters. Ifanelekile ekufumaneni i-live okanye ukusilela kombane kwe-zinc oxide arresters zamanqanaba ahlukeneyo e-voltage, kunye nokufumanisa ngexesha elifanelekileyo iziphene eziyingozi ezifana nokufuma kwi-insulation yangaphakathi yezixhobo kunye nokuguga kwee-valve plates.

Izixhobo zilula kwaye kulula ukuzisebenzisa, kwaye yonke inkqubo yokulinganisa ilawulwa yi-IPC, i-total current elinganisiweyo, i-resistive current kunye ne-harmonics zayo ze-MOA, i-frequency reference voltage kunye ne-harmonics zayo, amandla asebenzayo kunye nesigaba, i-voltage yokwenyani kunye ne-current waveform. Esi sixhobo sisebenzisa uhlalutyo lwe-digital waveform, uhlalutyo lwe-harmonic kunye neziphumo ezichanekileyo, indlela yokucoca yedijithali ezinzileyo yokuphazamiseka kwesoftware, kunye nohlalutyo oluchanekileyo oluphindwe kathathu ukuya kwi-7 kumxholo osisiseko we-harmonic, kwaye soyise isigaba sokuphazamiseka, isigaba esichanekileyo se-resistance current Measure ecaleni kwe-arrester.

Kwimeko yokucima kombane kwe-transformer, nceda uqhagamshele ucingo olusemgangathweni oluthembekileyo lwesixhobo kunye ne-transformer yovavanyo kuqala, uze uqhagamshele ucingo lovavanyo lwangoku (iingcingo ezimthubi, eziluhlaza nezimthubi zeengcingo ezintathu eziphambili ziqhagamshelene kwiziphelo ezisezantsi ze-zinc oxide arresters ezintathu), uze ekugqibeleni uqhagamshele ucingo lovavanyo lwe-Voltage oluxhathisayo (iingcingo ezimthubi, eziluhlaza nezibomvu zeengcingo ezine eziphambili ziqhagamshelene kwelinye icala le-transformer yokulinganisa i-winding, kwaye ucingo olumnyama luqhagamshelene kwelinye icala le-transformer yokulinganisa i-winding, qaphela icala, ukuba imiyalelo ayinakulungelelaniswa).

Xa idibene nomgca wovavanyo wangoku, okokuqala, ngokobukhulu balo mbane, umgca wovavanyo wangoku ufikelela kuluhlu oluphezulu lomsingathi “0-2mA” okanye “>2mA” (2-10mA >2mA ijika eliqhelekileyo), uze emva koko kuthiwe Kwelinye icala lendlela, i-oxide MOA iyancitshiswa. Indlela yokudibanisa umgca wovavanyo we-voltage kukudibanisa imitha kuqala, uze udibanise i-transformer test winding. Emva kokujonga i-wiring echanekileyo, yonyusa kancinci i-voltage ukuya kwi-voltage esebenzayo ye-zinc oxide arrester, uze usebenzise isixhobo ukuqala uvavanyo.
