Apakah kerosakan busur?<\/h2>\n

Secara ringkas, kerosakan busur ialah elektrik \u201cmelompat\u201d atau \u201cberpercikan.\u201d Dalam keadaan biasa, arus elektrik mengalir dengan tertib di sepanjang wayar. Tetapi apabila penebat wayar menua atau rosak, atau apabila sambungan menjadi longgar, arus mengambil laluan alternatif\u2014ia melompat merentasi jurang udara, menghasilkan percikan terang. Inilah kerosakan busur.<\/p>\n

\"Prinsip<\/p>\n

Sejauh manakah bahaya kerosakan busur elektrik?<\/h2>\n

Kegagalan busur menghasilkan suhu yang amat tinggi, dengan suhu teras melebihi 3000\u00b0C\u2014lebih panas daripada proses kimpalan! Ia boleh menyala serta-merta bahan bakar di sekeliling seperti kayu, fabrik, dan plastik. Statistik menunjukkan bahawa sebahagian besar kebakaran elektrik disebabkan oleh kegagalan busur. Lebih menakutkan lagi, busur bersiri (\u201csambungan longgar\u201d dalam litar) mengalirkan arus yang sangat kecil sehingga pemutus litar biasa tidak dapat mengesan, namun bahaya kebakaran tetap wujud.<\/p>\n

Bagaimana AFDD<\/a> \u201cNampak\u201d Kegagalan Litar Lengkung?<\/h2>\n

AFDD (Peranti Pengesan Kegagalan Busur) berfungsi seperti \u201cmata api\u201d untuk litar elektrik anda. Ia mengandungi sensor yang sangat sensitif yang memantau bentuk gelombang arus secara masa nyata. Bentuk gelombang arus biasa adalah lancar dan teratur, manakala arus busur menunjukkan ciri mutasi \u201cgigi gergaji\u201d. AFDD menggunakan algoritma pintar untuk menganalisis ciri bentuk gelombang ini, mengenal pasti busur berbahaya dalam milisaat dan segera memutuskan bekalan kuasa.<\/p>\n

Lengkungan Siri vs. Lengkungan Selari<\/h2>\n
    \n
  • Busur Siri<\/strong>: Berlakunya pada konduktor yang sama, seperti putusnya wayar dalaman atau sambungan longgar. Laluan arus menjadi \u201cterlentang,\u201d menghasilkan busur.<\/li>\n
  • Busur Paralel<\/strong>: Berlakunya antara wayar hidup dan wayar neutral, seperti apabila penebat rosak menyebabkan kedua-dua wayar itu bersentuhan. Jenis busur ini membawa lebih banyak tenaga dan lebih berbahaya.<\/li>\n<\/ul>\n

    AFDD boleh mengesan dan melindungi dengan berkesan terhadap kedua-dua jenis kerosakan busur.<\/p>\n

    Mengapa Rumah Anda Perlu AFDD?<\/h2>\n

    Pemutus litar tradisional dan RCD (peranti arus tinggalan) hanya melindungi daripada beban berlebihan, litar pintas, dan kebocoran\u2014mereka tidak berdaya menentang kebakaran akibat kerosakan busur. AFDD secara khusus mengisi jurang keselamatan ini. Ia amat sesuai untuk rumah lama, struktur kayu, dan isi rumah yang menggunakan perkakas berkuasa tinggi. Memasang AFDD adalah seperti menambah \u201ctembok api\u201d pada sistem elektrik anda, memberikan keluarga anda ketenangan fikiran yang lebih besar.<\/p>","protected":false},"excerpt":{"rendered":"
