Siemens presents the HIS (Highly Integrated Switchgear) Type 8DQ1, a groundbreaking solution designed to overcome space limitations in power substations. This gas-insulated switchgear offers a compact and efficient alternative to traditional air-insulated switchgear, requiring less than half the space while maintaining high performance and reliability.
The 8DQ1 series is engineered for rated voltages up to 550 kV, making it suitable for a wide range of applications, including the cost-effective renewal or expansion of existing substations. Its modular design allows for flexible configuration using standardized modules, enabling the implementation of all common substation layouts. Key components such as circuit breakers, instrument transformers, and disconnecting/earthing switches are housed in pressure-gas-tight enclosures, ensuring safety and minimizing environmental impact.
Siemens' HIS switchgear is characterized by its low operating costs, minimal maintenance requirements, and a long service life, contributing to reduced life-cycle costs. The pre-assembled and factory-tested units simplify on-site installation and commissioning. The system is designed for seamless integration with existing control and protection concepts, whether conventional, digital, or process-bus based.
Safety is paramount, with the enclosed design protecting personnel from live parts. The switchgear also offers robust protection against vandalism and environmental factors, ensuring reliable operation even in challenging conditions.
