 Penguji Nisbah Semasa, Penguji Nisbah Pusingan Transformer Tiga Fasa TTR<\/strong><\/p>\n\n\n\n

Ujian nisbah memastikan lilitan trafo mempunyai pusingan yang betul untuk menghasilkan voltan yang diperlukan. Nisbah ialah ukuran voltan yang dikenakan pada terminal primer berbanding voltan yang diukur pada terminal sekunder.<\/p>\n\n\n

Apakah tujuan ujian nisbah lilitan trafo?<\/strong><\/p>\n\n\n\n

Ujian nisbah lilitan transformator digunakan untuk menentukan bilangan lilitan dalam satu lilitan transformator berbanding bilangan lilitan dalam lilitan lain pada fasa yang sama. Ujian polariti transformator menentukan hubungan vektor antara pelbagai lilitan transformator.<\/p>\n\n\n\n

Mengapa kita perlu menguji nisbah putaran transformator?<\/h1>\n\n\n\n

Sebagai contoh, dalam sistem kuasa, dua trafo biasanya dioperasikan selari, dan kedua-dua trafo itu perlu berada pada fasa yang sama, dan perbezaan fasa antara kedua-dua trafo tidak boleh melebihi 0.5%, jika tidak, kitaran besar akan berlaku antara kedua-dua trafo, dan kerugian trafo akan meningkat, yang mudah menyebabkan kerosakan, seperti litar pintas atau litar terbuka pada lilitan, kerosakan atau terbakar pada lilitan, dan deformasi lilitan. Kerosakan ini akan menjejaskan kebolehpercayaan lilitan trafo. Kemerosotan parameter nisbah trafo boleh mencerminkan beberapa kerosakan trafo. Ujian nisbah trafo boleh mengesan litar pintas antara lilitan (interturn), litar terbuka, kerosakan dan pembakaran lilitan serta kerosakan lain, dan kaedahnya mudah, jadi trafo perlu diuji nisbahnya sebelum operasi atau selepas kerosakan untuk menentukan sama ada trafo boleh berfungsi dengan normal.<\/p>","protected":false},"excerpt":{"rendered":"
