Intelligent touch-controlled, all-condition, fully sealed, environmentally friendly high-voltage switchgear and control equipment

Product Innovation and Features:

1. Miniaturization: Suitable for use along streets, sidewalks, and various humid environments without compromising urban aesthetics or obstructing visibility, while also saving space and being resistant to condensation and water seepage.

2. Fully Sealed: The circuit breaker and three-position switch are housed in a fully sealed, modular assembly. Additionally, secondary components, secondary circuits, and control systems are entirely enclosed, ensuring the entire switchgear can withstand 7 days of submersion in water.

3. Metering Cabinet: Achieve a fully sealed, miniaturized metering cabinet.

IV. Deep Integration: The DTU, power-taking module, measurement sensors, instrumentation, and backup power supply are integrated into a single unit, eliminating the need for separate voltage transformer cabinets, independent DTU control cabinets, and dedicated power supply cabinets in the distribution cabinet assembly.

V. Intelligent Features: Comprehensive monitoring of operational status, equipped with remote support capabilities, and featuring intelligent protection against erroneous operations.

6. Fully Insulated and Fully Grounded: All high-voltage conductive components of the equipment are completely enclosed within an insulating body that features surface shielding and grounding, ensuring no parts are exposed while providing long-lasting external grounding functionality.

7. Convenient Operation: No need to open the cabinet door—simply use the industrial-grade touchscreen, allowing even non-technical personnel to perform operations smoothly and safely.

8. High Reliability: High-precision sensors replace current transformers, significantly enhancing equipment reliability. The circuit breaker operates swiftly, enabling short-time coordination with a difference as low as 70 milliseconds—and can also achieve automatic dual-power source switching within 70 to 80 milliseconds.

9. High Accuracy in Fault Diagnosis: The accuracy of local section isolation for single-phase-to-ground faults reaches over 90%, while short-circuit faults achieve 100% accuracy.

10. Simple Installation and Eco-Friendly: Each switchgear cabinet is pre-integrated and assembled at the factory, eliminating the need for users to connect busbars or assemble cabinets on-site. All that’s required is a single entry/exit cable connection and the installation of a high-voltage meter—plus, there’s zero emission of any toxic substances.

11. Minimal Maintenance: Primary equipment requires no maintenance for 30 years, while secondary equipment is maintenance-free for 10 years. No adjustments are needed during commissioning or operation.

12. Compliant with relevant standards such as GB1984, GB11022, GB1985, GB3906, IEC62271-200, and more, it meets the three-proof requirements and is suitable for offshore operations.
