KYN28-30 Indoor Metal – Clad Withdrawable Switchgear

1. Exclusive optimization for long-distance transmission, precise voltage drop control:

For 30kV voltage level topology optimization, equipped with high-precision reactive power compensation and voltage regulation modules, the voltage drop of 15-20km long-distance transmission can be controlled within ± 3%, which is better than conventional medium and high voltage products, ensuring stable terminal load voltage.

2. Composite insulation upgrade and safety boundary expansion:

Imported solid composite insulation materials are used, with insulation distances between phases and relative to ground reaching 60kV level standards. Combined with partial discharge and insulation dual online monitoring systems, it can withstand lightning overvoltage and operating overvoltage, eliminating the risk of ultra-high voltage insulation breakdown.

3. Large capacity adaptation, excellent breaking performance:

rated current of 2500A-5000A, short-circuit breaking capacity of 80kA-125kA, short-term withstand current of 100kA (3s), equipped with ultra large capacity vacuum circuit breaker, can adapt to the needs of ultra large loads and rapid fault current cutting in new energy bases.

4. New energy linkage with strong adaptability to fluctuations:

Supports the IEC 61850-9-2 high-speed communication protocol, seamlessly integrates with new energy dispatch platforms, and has wide range voltage adaptation and reactive power regulation functions. It can effectively control the volatility of wind and photovoltaic power generation and ensure grid stability.

5. Extreme weather resistant design, wide scene coverage:

The cabinet adopts fluorocarbon coating+stainless steel frame, and the internal components are made of temperature resistant, salt spray resistant, and dust resistant materials. It can operate stably in extreme temperatures and high corrosion environments from -35 ℃ to 55 ℃, and is suitable for outdoor and indoor transfer and remote scenes.

The product supports full vacuum circuit breaker or SF6 insulated circuit breaker configuration, and can be optionally equipped with a permanent magnet operating mechanism (mechanical life ≥ 100000 times); The default protection level is IP54, which can be upgraded to IP65; The intelligent module integrates power quality monitoring, fault location, and health prediction functions, supporting multi-dimensional data visualization; Provide national level type test reports, energy-saving certification, and pollution resistance level IV certificate, with a rated short-time withstand current of 80kA-100kA (3s), and can customize explosion-proof types to adapt to special industrial scenarios.
