Berikut adalah panduan lengkap Wiring Diagram Konvensional Sistem Starter Star-Delta (Bintang-Segitiga)<\/strong> otomatis menggunakan timer mekanis gaya lama. Rangkaian ini sangat krusial di pabrik model dahulu untuk menurunkan lonjakan arus start (inrush current<\/em>) pada motor 3-Fasa berkapasitas besar (biasanya di atas 5,5 kW \/ 7,5 HP).<\/p>\n\n\n\n

\n\n\n\n

1. Komponen Utama Rangkaian Star-Delta<\/h2>\n\n\n\n

Untuk merakit panel model konvensional ini, Anda membutuhkan:<\/p>\n\n\n\n

    \n
  • 3 Unit Kontaktor Utama<\/strong>:\n
      \n
    • K1 (Main Contactor \/ Kontaktor Utama)<\/strong><\/li>\n\n\n\n
    • K2 (Delta Contactor \/ Kontaktor Segitiga)<\/strong><\/li>\n\n\n\n
    • K3 (Star Contactor \/ Kontaktor Bintang)<\/strong><\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • 1 Unit Timer Relay (T1)<\/strong>: Mengatur jeda perpindahan waktu secara otomatis dari Star ke Delta (biasanya disetel 4\u20137 detik).<\/li>\n\n\n\n
    • 1 Unit Thermal Overload Relay (TOR)<\/strong>: Pengaman beban lebih.<\/li>\n\n\n\n
    • Push Button<\/strong>: 1 Tombol STOP (NC) dan 1 Tombol START (NO).<\/li>\n\n\n\n
    • MCB 3-Phase & MCB 1-Phase<\/strong>: Sebagai pengaman hubungan singkat.<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      2. Panduan Rangkaian Daya (Power Circuit)<\/h2>\n\n\n\n

      Rangkaian daya mengalirkan tegangan tinggi 3-Phase (R, S, T<\/strong>) ke 6 terminal motor (U1, V1, W1<\/strong> dan U2, V2, W2<\/strong>).<\/p>\n\n\n\n

        \n
      1. Jalur Input Utama:<\/strong>\n
          \n
        • Hubungkan sumber R, S, T<\/strong> ke input MCB 3-Phase<\/strong>.<\/li>\n\n\n\n
        • Output dari MCB 3-Phase dicabangkan paralel ke bagian atas kontak utama Kontaktor Utama (K1)<\/strong> dan Kontaktor Delta (K2)<\/strong> dengan urutan fasa yang sama (R-S-T).<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Jalur Menuju Motor Bagian 1 (U1, V1, W1):<\/strong>\n
            \n
          • Pasang TOR<\/strong> di bawah Kontaktor Utama (K1).<\/li>\n\n\n\n
          • Output dari TOR dihubungkan langsung ke terminal motor U1, V1, W1<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
          • Jalur Menuju Motor Bagian 2 (U2, V2, W2):<\/strong>\n
              \n
            • Output dari bawah Kontaktor Delta (K2) dihubungkan ke terminal motor U2, V2, W2<\/strong>. Catatan penting: Pastikan konfigurasi kabel fasa di sini disesuaikan agar saat Delta aktif, belitan motor menerima tegangan penuh antar-fasa (inter-phase).<\/em><\/li>\n<\/ul>\n<\/li>\n\n\n\n
            • Jalur Hubung Singkat Bintang (Star – K3):<\/strong>\n
                \n
              • Bagian atas Kontak Utama Kontaktor Star (K3)<\/strong> dijumper (dihubungkan singkat) semuanya menjadi satu titik netral buatan.<\/li>\n\n\n\n
              • Bagian bawah Kontaktor Star (K3) dihubungkan paralel dengan bagian bawah Kontaktor Delta (K2) menuju terminal motor U2, V2, W2<\/strong>.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
                \n\n\n\n

                3. Panduan Rangkaian Kontrol (Control Circuit)<\/h2>\n\n\n\n

                Rangkaian kontrol konvensional wajib menggunakan sistem Interlocking Mekanis-Elektrik<\/strong> agar Kontaktor Star (K3) dan Kontaktor Delta (K2) tidak akan pernah bisa menyala bersamaan<\/strong> (jika menyala bersamaan, akan terjadi ledakan\/korsleting hebat).<\/p>\n\n\n\n

                Gunakan tegangan 1-Phase (Fasa R<\/strong> ke Netral N<\/strong>):<\/p>\n\n\n\n

                  \n
                1. Pengaman Awal:<\/strong> Dari output MCB 1-Phase $\\rightarrow$ masuk ke kontak TOR (NC 95-96)<\/strong> $\\rightarrow$ keluar menuju Push Button STOP (NC)<\/strong>.<\/li>\n\n\n\n
                2. Sistem Pengunci START:<\/strong> Dari output PB STOP $\\rightarrow$ masuk ke Push Button START (NO)<\/strong>. Paralelkan PB START ini dengan kontak bantu NO (13-14) milik Kontaktor Utama (K1)<\/strong> sebagai pengunci elektrik.<\/li>\n\n\n\n
                3. Menyalakan Jalur Utama:<\/strong> Output dari PB START dihubungkan langsung untuk menyalakan Koil A1 Kontaktor Utama (K1)<\/strong> dan Koil Timer (T1)<\/strong>.<\/li>\n\n\n\n
                4. Jalur Pengendali Star (K3) – Melalui Timer NC:<\/strong>\n
                    \n
                  • Ambil arus dari output PB START $\\rightarrow$ masukkan ke Kontak NC milik Timer (T1)<\/strong>.<\/li>\n\n\n\n
                  • Keluar dari NC Timer $\\rightarrow$ masukkan ke Kontak NC milik Kontaktor Delta (K2)<\/strong> (sebagai sistem Interlock elektrik)<\/em>.<\/li>\n\n\n\n
                  • Keluar dari NC K2 $\\rightarrow$ hubungkan langsung ke Koil A1 Kontaktor Star (K3)<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
                  • Jalur Pengendali Delta (K2) – Melalui Timer NO:<\/strong>\n
                      \n
                    • Ambil arus dari output PB START $\\rightarrow$ masukkan ke Kontak NO milik Timer (T1)<\/strong>.<\/li>\n\n\n\n
                    • Keluar dari NO Timer $\\rightarrow$ masukkan ke Kontak NC milik Kontaktor Star (K3)<\/strong> (sebagai sistem Interlock elektrik)<\/em>.<\/li>\n\n\n\n
                    • Keluar dari NC K3 $\\rightarrow$ hubungkan langsung ke Koil A1 Kontaktor Delta (K2)<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
                    • Jalur Netral:<\/strong> Hubungkan semua terminal A2<\/strong> dari seluruh Koil Kontor (K1, K2, K3) dan Timer (T1) ke kabel Netral (N)<\/strong> sumber listrik.<\/li>\n<\/ol>\n\n\n\n
                      \n\n\n\n

                      4. Cara Kerja Rangkaian (Logika Konvensional Tempo Dulu)<\/h2>\n\n\n\n
                        \n
                      • Langkah 1 (Start – Posisi Star):<\/strong> Ketika tombol START<\/strong> ditekan, Kontaktor K1 (Utama)<\/strong>, Timer T1<\/strong>, dan Kontaktor K3 (Star)<\/strong> langsung aktif bersamaan. Motor berputar lambat dan halus dengan hubungan Bintang (tegangan per belitan hanya $\\approx 220\\text{V}$, menghemat arus awal pabrik).<\/li>\n\n\n\n
                      • Langkah 2 (Proses Hitung Mundur):<\/strong> Timer (T1) mulai menghitung waktu (misal 5 detik) seiring motor mulai mencapai $\\approx 80\\%$ kecepatan penuhnya.<\/li>\n\n\n\n
                      • Langkah 3 (Transisi ke Delta):<\/strong> Setelah 5 detik, kontak NC Timer terbuka<\/strong> (memutus Kontaktor Star K3 hingga mati) dan sepersekian detik kemudian kontak NO Timer menutup<\/strong> (menyalakan Kontaktor Delta K2).<\/li>\n\n\n\n
                      • Langkah 4 (Running – Posisi Delta):<\/strong> Motor kini beroperasi penuh dengan hubungan Segitiga (tegangan penuh per belitan $\\approx 380\\text{V}$) untuk menahan beban kerja pabrik yang sesungguhnya. <\/li>\n<\/ul>\n\n\n\n
