I-GDRB-C Power Transformer Wining Deformation Tester
I-Power transformer winding deformation tester (indlela yokuphendula imvamisa) isekelwe ekukalweni kwemingcele yesici se-transformer windings yangaphakathi, yamukela indlela yokuhlaziya imvamisa yephutha yangaphakathi (FRA), ingahlulela ngokunembile amaphutha angaphakathi ama-transformer.
Ngemuva kokuphothulwa kokuklama nokukhiqizwa kwama-transformer, amakhoyili kanye nesakhiwo sangaphakathi kuyaqedwa, ngakho-ke ngekhoyili ye-multi-winding transformer, uma izinga le-voltage kanye nendlela yokuphefumula kufana, imingcele ehambisanayo (Ci, Li) ngayinye. ikhoyili izonqunywa.Ngakho-ke, ukusabela kwezimpawu zemvamisa yekhoyili ngayinye nakho kuzonqunywa, ngakho-ke izilinganiso zefrikhwensi zamakhoyili ahambisanayo ezigaba ezintathu ziyaqhathaniswa.
Ngesikhathi sokuhlolwa kwe-transformer, uma kwenzeka kuba ne-inter-turn, inter-phase short circuit, noma ukufuduka kwekhoyili okuhlobene okubangelwa ukushayisana ngesikhathi sokuthutha, kanye nokuguqulwa kwekhoyili okubangelwa ukungezwani kwamandla kazibuthe ngesikhathi sokusebenza ngaphansi kwezimo ezimfushane nezimo zephutha, imingcele yokusabalalisa. ama-windings e-transformer azoshintsha, okuthi ngaleyo ndlela kube nomthelela futhi kuguqule izici zesizinda samafrikhwensi asekuqaleni, okungukuthi ukuguquka kwempendulo yefrikhwensi ngobukhulu kanye nokuguquguquka kwamaphoyinti efrikhwensi.Isihloli sokuvundisa i-transformer esakhiwe ngokwendlela yokuhlaziya impendulo iyinoveli yemishini ye-NDT yokuthola iphutha langaphakathi le-transformer.Kusebenza ekutholweni kwephutha lesakhiwo sangaphakathi kuma-transformer amandla angu-63kV-500kV.
Umhloli we-Transformer winding deformation ukunquma izinga lezinguquko kuma-winding angaphakathi e-transformer ngokusekelwe enanini loshintsho, ubukhulu kanye nesifunda esithinta ushintsho kanye nokuthambekela kokushintsha kwe-frequency yokuphendula okulinganiswa kusukela ekushintsheni kwempendulo ezizindeni ezihlukene zefrikhwensi yamajika angaphakathi e-transformer. amapharamitha, bese ingakusiza ukuthi unqume ukuthi i-transformer yonakaliswe kakhulu, noma idinga ukulungiswa okukhulu ngokuhambisana nemiphumela yokulinganisa.
Ku-transformer esebenzayo, kungakhathaliseki ukuthi umdwebo wesici sesizinda se-frequency ulondoloziwe, ngokuqhathanisa umehluko phakathi kwe-spectra yesici se-inter-coil ye-transformer enephutha, inganquma izinga lokuhluleka futhi.Yiqiniso, uma ulondoloze imidwebo yesici sokuqala se-transformer windings, kuyoba lula ukunikeza isisekelo esiqondile sezimo zokusebenza, ukuhlaziywa kwe-post-fault kanye nokulungiswa kokugcinwa kwe-transformer.
Umhloli wokuguquguquka ojikajikayo we-Transformer wakhiwa ikhompuyutha ephathekayo nesilawuli esincane esakha isistimu yokulinganisa ukunemba ngesakhiwo esihlangene, ukusebenza okulula, nomsebenzi wokuhlaziya ophelele kakhudlwana, ongasetshenzwa kubhekiselwa kumanuwali weziqondiso noma ngokuqeqeshwa kwesikhashana.
●Ukuthola nokulawula kusetshenziswa i-microprocessor enesivinini esikhulu, edidiyelwe kakhulu.
●Isixhumanisi esibonakalayo se-USB sokuxhumana esisetshenziswa phakathi kwekhompyutha ephathekayo nensimbi.
●Akudingekile ukusebenzisa ikhompyutha ephathwayo emkhakheni wokulinganisa ngenxa yokuhlanganiswa kwekhompuyutha yezimboni kanye nethuluzi lokulinganisa.
●Izingxenyekazi zekhompuyutha zamukela ubuchwepheshe bokuskena bedijithali be-DDS obuzinikezele bedijithali (i-USA), obukwazi ukuhlonza ngokunembile amaphutha njengokuphenduka okusontekile, okugobile, ukuguquka, ukutsheka, ukuguquguquka kwe-inter-turn short-circuit kanye ne-inter- phase contact short-circuit.
●Isampula ye-speed dual-channel 16-bit A/D (esivivinyweni senkambu, hambisa isishintshi sompompi, futhi ijika lamagagasi libonisa izinguquko ezisobala) .
●I-amplitude yokuphuma kwesignali ilungiswa isofthiwe, futhi inani eliphakeme le-amplitude ngu-± 10V.
●Ikhompyutha izozihlaziya ngokuzenzakalelayo imiphumela yokuhlolwa bese ikhiqiza imibhalo ye-elekthronikhi (iZwi).
●Ithuluzi linezici zokulinganisa ezimbili: ukulinganisa imvamisa yokuskena okuqondile kanye nesilinganiso sokuskena imvamisa yengxenye, ehambisana nemodi yokulinganisa yamaqembu amabili obuchwepheshe e-China.
●Izici ze-amplitude-frequency zihambisana nezicaciso zobuchwepheshe kazwelonke kumhloli wezimpawu ze-amplitude-frequency.I-X-coordinate (imvamisa) inokukhomba ngomugqa kanye ne-logarithmic indexing, ngakho-ke umsebenzisi angakwazi ukuphrinta ijika nge indexing yomugqa kanye ne-logarithmic indexing.Umsebenzisi angakhetha noma ngokwezidingo zangempela.
●Uhlelo lokuhlaziya idatha oluzenzakalelayo,
Ukuqhathaniswa okuvundlile kokufana okumazombezombe phakathi kwezigaba ezintathu A, B kanye no-C
