Pendahuluan<\/h2>\n

FN18 is a general purpose, three-pole, load break switch that offers switchgear owners and assemblers the advantages of an advanced interrupting technology and proven, dependable performance in a compact design.<\/p>\n

The switch is available to switchgear assemblers as a building block for metal-enclosed and pad-mounted switchgear applications in ratings from 12 upto 24kV.<\/p>\n

The standard FN18 switch includes a heavy-duty steel frame with stand-off insulators, a unique puffer-type arc extinguishing system, an operating mechanism and current-carrying components, including blade-type interrupters with cast hinges and jaw connectors.<\/p>\n

Optional accessories and features include a variety of operating handles, a motor operator, auxiliary switches, a shunt trip device, fuse bases, mechanical fuse tripping, grounding switches, mechanical door interlocking and key interlocking.<\/p>\n

 <\/p>\n

Fitur Produk Utama<\/h2>\n

Pemutus sakelar FN18 didasarkan pada prinsip modular, yang memberikan berbagai macam fungsi. Dengan desain unik yang memadamkan busur listrik dan memungkinkan
\nhigh switching capacity, they represent an attractive solution as a key breaking element for applications in enclosed switchgear and transformer compact substations.<\/p>\n

In combination with current limiting fuses, FN18-F fuse switch disconnectors ensure control over the full range of overload and short-circuit currents.<\/p>\n

The basic unit consists of a frame with insulators and current carrying parts.<\/p>\n

Two different types of operating mechanisms, snap action mechanism type K or stored spring energy mechanism type A, can be mounted on the frame.<\/p>\n

Fuse bases with or without fuse tripping mechanism, and an earthing switch type , suitable for both direct mounting and free standing components, complete the basic equipment of a switch disconnector. These modules can be easily configured according
\nto customer expectations.<\/p>\n

Accessories, such as shunt trip, under-voltage release, auxiliary switches, motor operation and various systems for manual operation can easily be added.<\/p>\n

  • \n

    Sakelar pemutus beban FN18<\/h3>\n<\/li>\n<\/ul>\n

    Fitur standar terdiri dari sasis, isolator, dan arus
    \nmembawa komponen dengan jarak tiang berikut ini:
    \n- 12 kV - jarak tiang 150 mm, 170 mm, dan 210 mm
    \n- 17,5 kV - jarak tiang 170 mm dan 210 mm
    \n- 24 kV - jarak tiang 170 mm*, 235 mm dan 275 mm
    \n- 36\/40,5 kV - jarak tiang 360 mm
    \n* - dengan penghalang isolasi
    \nArus yang dinilai adalah:
    \n- 400, 630 dan 1250 A hingga 24 kV
    \n- 630\/800\/1000 A untuk 36\/40,5 kV<\/h4>\n
      \n
    • \n

      Sakelar pemutus beban FN18 dengan sekring<\/h3>\n<\/li>\n<\/ul>\n

      Dikirim dengan jarak tiang yang sama seperti fitur standar.
      \nBasis sekring tipe F dikirimkan untuk pemasangan pada sisi bukaan dan pivot, dengan atau tanpa tripping otomatis.
      \nBasis sekring dengan enam isolator juga dapat dikirim secara terpisah dengan beberapa bentuk indikasi sinyal ketika sekring putus atau untuk pemasangan di sisi poros sakelar<\/p>\n

        \n
      • \n

        Mekanisme<\/h3>\n<\/li>\n<\/ul>\n

        Tipe A dengan dua pegas
        \nPegas pembuka selalu diisi sebelum sakelar dapat ditutup melalui pegas penutup. Ini berarti pegas pembuka selalu diisi dalam sakelar tertutup, yang pada gilirannya dapat berupa
        \nsegera tersandung dengan tangan, secara elektrik atau dengan sistem penyerang sekring.<\/p>\n

        Tipe K dengan satu pegas
        \nMenutup atau membuka sakelar dilakukan dengan mengisi daya pegas melewati bagian tengah yang mati.<\/p>\n

        Mekanisme A dan K dapat bekerja sama dengan drive motor.<\/p>\n

          \n
        • \n

          Sakelar Pembumian<\/h3>\n<\/li>\n<\/ul>\n

          Sakelar pembumian tipe D<\/p>\n

          Sakelar pembumian jenis ini dilengkapi dengan mekanisme pegas cepat. Sakelar ini dapat dipasang di sisi poros sakelar
          \npemisah atau pada dasar sekering ketika yang terakhir berada di poros
          \nsisi sakelar.<\/p>\n

          Sakelar pembumian tipe DB<\/p>\n

          Dirancang untuk menjadi rakitan independen untuk kedua sisi
          \npemisah.<\/p>\n
