Product Deskripsi

IE-12kV/630A pole-mounted SF6 circuit breaker is a complete set of pole-mounted switch products developed in accordance with primary and secondary fusion standards. The switch has a compact structure, reasonable layout, and complete functions. All indicators meet the primary and secondary fusion technical requirements; built-in high Precision current transformers, zero-sequence current transformers, and zero-sequence voltage sensors have the characteristics of wide measurement range, high measurement accuracy, stable reliability, and small power loss. The complete analog quantities are convenient for accurately determining various line faults.

The 12kV-630A pole-mounted SF6 circuit breaker cooperates with the FTU and has intelligent functions such as measurement, protection, control, signaling, telecontrol and networking, online monitoring and diagnosis, accurate judgment of grounding points, line loss measurement, and fault recording. It is suitable for 12kV overhead distribution lines and user branch lines. It can quickly separate the fault section and isolate the fault within the user boundary section to prevent user faults from spreading to the entire distribution line and causing large-scale power outages.

SF6 utama Circuit Breaker Sahli sihir Pseni:

  1. This product has significant advantages such as simple structure, excellent arc extinguishing and insulation performance, low operating power, high rated parameters, long electrical life and long non-maintenance period.
  2. Kotak suis diperbuat daripada keluli tahan karat 304 untuk memenuhi keperluan rintangan kakisan untuk kegunaan kekal.
  3. The main circuit uses copper-tungsten alloy contacts, and the contact fingers adopt copper-tungsten alloy plum petal type, which has strong breaking capacity, large current withstand, high reliability, large contact opening distance when opening, and no leakage current between the fractures.
  4. Dilengkapi dengan alat pelepas tekanan tekanan tinggi, walaupun kegagalan dalaman berlaku, kotak tidak akan rosak akibat peningkatan mendadak dalam tekanan gas di dalam kotak.
  5. Install a low-pressure locking alarm device (optional). When the circuit breaker is under excessively low pressure, the low-pressure locking alarm device can effectively mechanically lock the operating mechanism and provide an auxiliary contact to the controller, thereby greatly improving the switching efficiencyand operational reliability.
  6. It has terminal incoming and outgoing lines and insulated cable incoming and outgoing lines. Insulated cable incoming and outgoing lines can effectively avoid short circuit faults between incoming and outgoing line terminals caused by external factors.
  7. Advanced porcelain casing technology for incoming and outgoing lines can be used to effectively prevent corona discharge during switch operation. Organic insulating sleeves can also be provided to completely prevent the rupture of porcelain bottles caused by external forces and lightning and cracking caused by porcelain factors.
  8. Configure CT/RVT protection device: In order to prevent overcurrent and CT open circuit of the current measuring device, the overvoltage product of the voltage measuring device is equipped with a CT/RVT protection module.
  9. Configure voltage sensor protection device: prevent overvoltage of phase voltage and zero sequence voltage sensors.

Three-level box type, simple structure and compact layout.

Installation and Adjustment

  1. Semak sama ada model dan spesifikasi pemutus litar konsisten dengan kontrak pesanan.
  2. Semak sama ada dokumen dan lampiran yang disertakan adalah lengkap.
  3. Periksa sama ada permukaan pemutus litar lebam dan sama ada bahagian penebat rosak atau retak.
  4. Periksa sama ada kotak itu cacat dan periksa pengedapnya.
  5. Are the fasteners loose?
  6. Manually or electrically operate the circuit breaker to close and open 10 times, and the opening and closing should be reliable.
  7. Check whether the pressure gauge pointer points to the green area.
  8. Menjalankan ujian lebihan arus, dan nilai tetapan lebihan arus harus memenuhi keperluan.
  9. When the product is damaged or has other questions, it is recommended to take photos of the damage on site and notify the manufacturer in time.
  10. Beri perhatian kepada keselamatan semasa mengangkat. Anda mesti mengaitkan empat gelang pengangkat pada kotak dan angkatnya secara mendatar.
  11. Fix the circuit breaker on the mounting bracket with bolts. The mounting surface should be flat. If the four mounting points are not on the same plane, washers should be added to adjust to prevent the overall structure of the circuit breaker from being deformed due to stress.
  12. Apabila pemutus litar disambungkan ke bar bas, hujung alur keluar pemutus litar tidak boleh tertakluk kepada ketegangan, tekanan atau tork kekal.
  13. Selepas pemasangan, pemutus litar hendaklah diperiksa dan dibersihkan.

Maintenance

  1. The circuit breaker should be inspected regularly and the contamination on the surface of the insulating parts should be removed.
  2. Check regularly whether the pressure gauge pointer is in the green area. If the pressure gauge pointer is close to the red area, contact the manufacturer for maintenance in time.
  3. For places with frequent operations, attention should be paid to the wear of the contacts, and the circuit breaker cannot be used beyond the allowable short-circuit breaking times and mechanical life.
  4. Perkara yang perlu diperhatikan:
  5. During maintenance, the circuit breaker should be in non-energy storage and open state, and all power supplies should be disconnected. Since the springs in the energy storage and closing states have accumulated energy, if you are not careful during maintenance, the movement of the mechanism may injure your hands.
  6. Penyelenggaraan harus dilakukan oleh profesional.
  7. Selepas penyelenggaraan, terutamanya selepas menggantikan bahagian atau menyesuaikan semula, ciri mekanikal suis perlu diuji untuk memastikan ia memenuhi syarat teknikal.
