AI Technical Summary

Technical Problem

Under heavy rain, the existing technology cannot effectively drain water from submersible pumps, which may still cause rainwater to backflow into the underground power distribution room, leading to equipment short circuits, tripping, and plant-wide voltage drops. Furthermore, existing measures cannot address this issue in a timely manner, affecting the stability of the power supply.

Method used

The system employs a drainage mechanism with a water storage funnel and a water-stop ring, combined with a leak detection and alarm device. It uses a leak detection belt and a submersible pump to drain water in a timely manner and notify staff, preventing water droplets from entering the equipment.

Benefits of technology

It effectively prevents rainwater from entering the power distribution room equipment, reduces the risk of equipment short circuits and tripping, ensures power supply stability, reduces overall plant voltage drop, and improves emergency response efficiency.
