AI Technical Summary
In existing technologies, the dual power supply design in explosion-proof locations leads to an increase in the number of distribution boxes, which occupy a large space, increase maintenance complexity, and the multi-box layout increases workload and safety risks.
The mains power and UPS power modules are integrated into a single distribution box. The internal cavity is divided into three independent chambers by an isolation structure, which are used for the mains power module, the UPS power module, and the terminal block module, respectively, to achieve electrical isolation and independent operation.
While achieving dual-circuit redundant power supply, it reduces the number of distribution boxes, saves space, improves maintenance convenience and safety, and ensures the continuity and reliability of power supply.
