Research on the Protection Scheme of a High-Speed Railway Crossing 1000 KV Ultra-High Voltage Transmission Line

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The study introduces a new structural form and construction method for the protective shed structure when the high-speed railway intersects with the 1000KV ultra-high-voltage transmission line project. This was achieved by research on the protection scheme, protection distance, protection load, and construction measures necessary in this condition. The results ensure the safe operation of the high-speed railway, achieve structural safety, and facilitate efficient construction in the safety zone near the upcoming 1000 KV ultra-high voltage transmission line. The paper is informative and original, and it serves as a useful reference for similar projects.

 

1、The article analyses the two working conditions of wire break and wire joint break within the span, the difference between these two working conditions is not clear, please add details.

2、The structural design only describes the structural selection, please add the structural dimensions, reinforcement and structural calculations considering each load condition.

3. Please translate the description in Figure 1 into English.

4. Pay attention to the form of Table 1. The new Roman font is recommended.

The article is a practical and interesting application of the theory. If I may suggest, wouldn't it be interesting to equip the tunnels with a Faraday cage on the inside and compare the results of the electromagnetic interactions.

This is a good suggestion but structure of this project is located outside the electromagnetic influence zone of the ultra-high voltage transmission line, and is less affected by electromagnetic interference.The design mainly considers collision safety protection in case of wire breakage during railway operation.Faraday cage can be a research direction that we can consider in the future
