صندوق توصيل JYN2

I. Product Overview

صندوق التوصيل JYN2 يستخدم هيكل راتنج الإيبوكسي المتكون عبر عملية APG (التصلب التلقائي بالضغط). إنه مكون اتصال عازل متخصص مصمم لسلسلة JYN2 من المفاتيح عالية الجهد القابلة للسحب (من نوع العربة). switchgearيُستخدم بشكل أساسي في المفاتيح الكهربائية القابلة للسحب بجهد 10 كيلوفولت - 35 كيلوفولت، ويعمل على توفير العزل والفصل والاتصال الانتقالي. يوفر حماية عزل فعالة للملامسات الداخلية، ويضمن التشغيل الآمن والمستقر لنظام الطاقة، ويلبي متطلبات التركيب للمفاتيح الكهربائية من سلسلة JYN2.

II. Technical Parameters

III. Scope of Application

This contact box is suitable for 10kV–35kV JYN2 series withdrawable switchgear. It is commonly used in power distribution systems, industrial substations, high-rise building distribution rooms, and distribution systems for industrial and mining enterprises. Acting as an insulating protection and transitional connection component for internal contacts, it ensures reliable insulation for the switching and isolation of high-voltage circuits, meeting the power distribution, control, and protection requirements of JYN2 series switchgear.

IV. Operating Conditions

1. Installation altitude must not exceed 1,000 meters;
2. Ambient air temperature range: -10°C to +40°C; daily average temperature not exceeding 35°C;
3. Ambient relative humidity: daily average ≤ 95%, monthly average ≤ 90%; relative humidity at 25°C not exceeding 95%;
4. The installation site must be free from gases, vapors, dust, or other explosive and corrosive media that could severely impair the insulation performance of the contact box;
5. Install in a location free from severe vibration or shock to ensure the structural stability of the product;
6. Seismic intensity at the installation site must not exceed Grade 8, and wind speed must not exceed 34 m/s.

V. Product Features

1. Excellent insulation performance: Manufactured using the epoxy resin APG (Automatic Pressure Gelation) process, offering superior insulation capabilities; effectively isolates high-voltage circuits, prevents leakage and short-circuit risks, and withstands high-voltage surges;
2. Stable and durable structure: The integrated molding structure provides high mechanical strength, enabling it to withstand mechanical and electrical stresses within the switchgear, ensuring a long service life;
3. Effective temperature rise control: Under long-term rated current operation, the temperature rise at the outlet terminals does not exceed 65°C, ensuring safe equipment operation and preventing failures caused by excessive heat;
4. Convenient installation: Standardized mounting dimensions compatible with JYN2 series withdrawable switchgear, facilitating on-site installation and replacement;
5. Corrosion and oxidation resistance: The epoxy resin material offers excellent resistance to corrosion and oxidation, making it suitable for various complex power system environments;
6. High-quality surface finish: Smooth surface free of burrs for easy installation; features excellent flame retardancy and wear resistance.
