PS-ZK03 Transformer Short Circuit Imedance Tester

I-impedance ye-short-circuit iparameter ebalulekileyo ye-transformer, kwaye indlela ye-impedance ye-short-circuit iyindlela yendabuko yokugweba ukuguqulwa kwe-winding. Ngokutsho kwe-GB1094.5-2003 kunye ne-IEC60076-5: 2000, inguqu ye-reactact ye-short-circuit kuphela kwekhrayitheriya yokugweba ukuba i-transformer winding ikhubazekile. Uvavanyo lwe-impedance ye-low-voltage ye-short-circuit impedance yeyona ndlela ichanekileyo yokukhangela ukuba i-winding iphazamisekile emva kokuba i-transformer ichaphazeleke ngumbane omfutshane ngexesha lokusebenza, okanye emva kokuba i-transformer ichaphazeleke ngamandla omatshini ngexesha lokuthutha kunye nokufakwa. Kubalulekile ukugweba ukuba i-transformer inokufakwa ekusebenzeni. Kwakhona enye yesiseko sokugweba ukuba i-transformer ifuna ukuhlolwa kwe-disassembly.

Intshayelelo yeNdawo yokuThengisa iMveliso

1. Umlinganiselo wesigaba esithathu sothintelo lwesekethe emfutshane:
Bonisa i-voltage yesigaba sesithathu, isigaba sesithathu sangoku, amandla amanqanaba amathathu; ukubala ngokuzenzekelayo ipesenti yombane we-impedance oguqulelwe kwiqondo lokushisa elilinganisiweyo kunye nexabiso langoku le-transformer, kunye nepesenti yephutha kunye ne-impedance ye-nameplate.
2. Umlinganiselo wesigaba esinye sothintelo lwesekethe emfutshane:
Ukulinganisa i-impedance ye-short-circuit ye-transformer yesigaba esisodwa.
3. Umlinganiselo we-zero-sequence impedance:
Umlinganiselo we-zero-sequence impedance ifanelekile kwi-transformers enendawo engathathi hlangothi ekudibaneni kweenkwenkwezi kwicala eliphezulu lombane.
4. Inokulinganiswa ngokuthe ngqo ngaphakathi kwinqanaba elivumelekileyo lokulinganisa isixhobo, kwaye i-voltage yangaphandle kunye nabaguquli bangoku banokudibaniswa ngaphandle koluhlu lokulinganisa. Isixhobo sinokuseta umlinganiselo wokuguqulwa kombane wangaphandle kunye nabaguquli bangoku, kwaye ubonise ngokuthe ngqo umbane osetyenzisiweyo kunye namaxabiso akhoyo.
5. Isixhobo samkela umbala wesikrini esikhulu se-LCD ye-high-resolution touch, imenyu yesiTshayina, i-Chinese prompts, kunye nokusebenza okulula.
6. Isixhobo siza kunye nomshicileli, onokuprinta kwaye ubonise idatha.
7. Imemori eyakhelwe-ngaphakathi engekho amandla-phantsi, inokugcina iiseti ze-200 zedatha yokulinganisa.
8. Isixhobo sixhotyiswe nge-U disk interface yokufikelela kwidatha yovavanyo.
9. Ikhalenda esisigxina, umsebenzi wewotshi, ulungelelwaniso lwexesha lunokwenziwa.
10. Isixhobo sinoluhlu olubanzi lokulinganisa, ukuchaneka okuphezulu kunye nokuzinza okulungileyo; ubungakanani obuncinci kunye nobunzima obulula bulungele ukulinganisa.
