KYN28-7.2 Indoor Metal – Clad Withdrawable Switchgear

1. High voltage adaptation with excellent rated parameters:

Optimized for 7.2kV high voltage working conditions, the rated current can reach 1250A-4000A, the short-circuit breaking capacity can reach 50kA-80kA, and the short-term withstand current ability is strong. It can be adapted to high voltage and large capacity distribution scenarios such as power plant auxiliary electricity and large transformer outlets.

2. Strengthen insulation and upgrade safety performance:

By using composite insulation materials and vacuum insulation technology, the insulation distance between phases and relative to ground is greatly increased. Equipped with insulation monitoring devices, the insulation status can be monitored in real time. At the same time, the cabinet adopts a grounding shielding design to effectively prevent high-voltage leakage and corona discharge, ensuring the safety of equipment and personnel.

3. Intelligent linkage, adapted to new energy scenarios:

It can seamlessly integrate with new energy generation systems such as wind power and photovoltaics, support a wide voltage input range, have reactive power compensation and power quality adjustment functions, effectively cope with the volatility of new energy generation, and ensure the stable operation of the distribution system.

4. Low noise operation, suitable for precision scenarios:

Optimize the design of the circuit breaker mechanism, use silent operating components, with a noise level of ≤ 60dB during operation. At the same time, the cabinet is equipped with shock absorbers to reduce vibration and noise pollution during equipment operation, and is suitable for power plant control rooms and precision laboratory power distribution scenarios.

5. Full lifecycle management, efficient operation and maintenance:

Integrated equipment health monitoring system can collect real-time data such as current, voltage, temperature, insulation status, etc., predict equipment failures through big data analysis, provide operation and maintenance suggestions, and support full lifecycle traceability of components to reduce operation and maintenance costs.

The product supports SF6 vacuum hybrid circuit breaker or full vacuum circuit breaker configuration, which can be selected according to user needs; The default protection level is IP4X, which can be upgraded to IP54. Explosion proof type (Ex d IIB T4) can be customized for special scenarios; The intelligent module supports integration with new energy control systems and power grid dispatch systems to achieve collaborative regulation; Provide comprehensive type test reports, factory inspection reports, and third-party certification certificates to ensure product compliance and reliability.
