Description of DPC-4-800/XC2 KYN28A Switchgear The DPC-4-800/XC2 KYN28A is a high-performance, metal-enclosed, indoor air-insulated switchgear designed for medium-voltage power distribution systems. It complies with international standards such as IEC 62271-200 and GB 3906, ensuring reliability and safety in industrial, commercial, and utility applications. Key Features 1. Voltage & Current Ratings - Rated voltage: 12 kV - Rated current: 800 A (main busbar) - Short-circuit breaking capacity: 31.5 kA (or higher, depending on configuration) 2. Robust Construction - The KYN28A design features a fully enclosed, partitioned metal structure with zinc-plated steel panels for corrosion resistance. - Modular compartments separate the circuit breaker, busbars, cable terminations, and relay protection units to enhance safety and maintenance efficiency. 3. Advanced Circuit Breaker Technology - Equipped with a spring-operated vacuum circuit breaker (VCB) for reliable arc quenching, low maintenance, and long service life. - The breaker can be manually or electrically operated (motorized option available). 4. Safety & Protection - "Five-proof" mechanical interlocking prevents incorrect operations (e.g., earthing switch closure on live circuits). - IP4X protection rating for internal components and IP3X for the overall cabinet, ensuring dust and foreign object resistance. - Pressure relief vents direct arc faults away from personnel in case of internal faults. 5. Flexible Configuration - Supports various schemes: feeder, transformer, bus coupler, and metering units. - Compatible with digital protection relays for overcurrent, earth fault, and other advanced protections. 6. Installation & Maintenance - Front-access design simplifies installation and servicing without rear access requirements. - Withdrawable breaker design allows quick isolation and replacement. Applications - Power plants, substations, and industrial plants (e.g., mining, oil & gas, manufacturing). - Renewable energy systems (solar/wind farms). - Urban infrastructure (hospitals, data centers, high-rise buildings). Advantages - Compact footprint saves space compared to conventional switchgear. - High durability with minimal maintenance needs due to vacuum interruption technology. - Enhanced operator safety through strict compliance with arc-flash prevention standards. This switchgear is ideal for demanding environments where reliability, safety, and efficiency are critical. Its modularity and compliance with global standards make it a versatile solution for modern power distribution networks.
