AI Technical Summary

Technical Problem

Due to the randomness and sporadic nature of lightning in railway signal machinery rooms, existing technologies result in low test timeliness and high costs. They are unable to effectively monitor the lightning-to-ground potential coupling between communication towers and machinery room grounding networks, posing a risk of equipment damage.

Method used

Provided is a lightning impulse test equipment and system. By conducting tests at a railway signal relay station under construction, a lightning impulse test circuit is constructed using voltage and current generating equipment, a bus circuit, and an acquisition terminal. This allows the coupling effect of the communication tower and the machinery room ground network to be reproduced, reducing costs and avoiding test risks.

Benefits of technology

Without any test risks, the coupling effect of lightning injection into the communication tower and its ground grid potential to the mechanical room was reproduced, which reduced the test cost, solved the problems of low test timeliness and high cost, and ensured personal safety.
