Memahami 2 Bagian Utama Wiring Star-Delta<\/strong><\/h2>\n\n\n\n

Di dalam panel listrik industri, rangkaian ini dibagi menjadi dua bagian yang saling bekerja sama:<\/p>\n\n\n\n

1. Rangkaian Daya (Power Circuit)<\/strong><\/h2>\n\n\n\n

Ini adalah jalur kabel besar yang mengalirkan arus listrik utama menuju motor 3-Phase. Komponen yang dipasang secara berurutan adalah:<\/p>\n\n\n\n

    \n
  • MCCB \/ MCB 3-Phase:<\/strong> Sebagai pengaman utama dari arus pendek (korsleting) di pabrik.<\/li>\n\n\n\n
  • Kontaktor Utama (Main Contactor – K1):<\/strong> Sakelar utama yang selalu aktif, baik saat motor dalam kondisi Star<\/em> maupun Delta<\/em>.<\/li>\n\n\n\n
  • TOR (Thermal Overload Relay):<\/strong> Dipasang tepat di bawah Kontaktor Utama untuk mendeteksi jika motor kepanasan atau kelebihan beban kerja.<\/li>\n\n\n\n
  • Kontaktor Star (K2):<\/strong> Ujung kabelnya dijumper (dihubungkan jadi satu titik) untuk menyatukan ujung belitan motor (U2, V2, W2) sehingga membentuk hubungan Bintang.<\/li>\n\n\n\n
  • Kontaktor Delta (K3):<\/strong> Menghubungkan ujung belitan secara bersilang (U1 ketemu V2, V1 ketemu W2, W1 ketemu U2) untuk menyuplai tegangan penuh 380V ke tiap belitan.<\/li>\n<\/ul>\n\n\n\n

    2. Rangkaian Kontrol (Control Circuit)<\/strong><\/h2>\n\n\n\n

    Ini adalah jalur kabel kecil (biasanya memakai kabel ukuran 0.75 mm atau 1 mm) yang berfungsi sebagai Otak Logika<\/strong> untuk mengatur kapan kontaktor harus hidup dan mati.<\/p>\n\n\n\n

      \n
    • Tombol NC (Stop):<\/strong> Untuk memutus seluruh aliran arus dan mematikan sistem.<\/li>\n\n\n\n
    • Tombol NO (Start):<\/strong> Untuk memicu arus masuk ke koil kontaktor.<\/li>\n\n\n\n
    • Timer Elektronik:<\/strong> Mengatur jeda detik (misal 5 detik) saat hubungan Star<\/em> aktif sebelum berpindah ke Delta<\/em>.<\/li>\n\n\n\n
    • Sistem Interlocking (Saling Mengunci):<\/strong> Kabel kontrol dikoneksikan melewati kontak NC milik lawan (NC K2 dipasang di jalur K3, dan sebaliknya). Tujuannya sangat vital:<\/em> mencegah Kontaktor Star dan Delta hidup bersamaan. Jika keduanya hidup bersamaan akibat salah kabel, panel akan meledak karena korsleting hebat.<\/li>\n<\/ul>\n\n\n\n
