Abstract

The invention belongs to the technical field of machine room lightning protection grounding. The invention particularly relates to an urban rail cloud platform machine room matrix type lightning protection grounding system and an access method thereof. The method comprises the following step that: electric equipment is equipotential through a grounding cable and is annularly accessed to a matrix type grounding body network. According to the invention, problems of worse grounding effect and unstable grounding caused by inconsistent grounding points and complex process in the prior art are solved; and the system and the access method have the beneficial technical effects of ensuring the overall reliability of grounding, avoiding the influence of the structure on the grounding effect, and simplifying and improving the stability of the system.

Description

technical field [0001] The invention belongs to the technical field of lightning protection and grounding for machine rooms, and in particular relates to a matrix type lightning protection and grounding system for a machine room on an urban rail cloud platform and an access method thereof. Background technique [0002] The urban rail cloud platform integrates the resources of each station to form a control center cloud platform system, uses centralized operation and maintenance management, unifies business processes and operating specifications, improves operation and maintenance efficiency, reduces the difficulty of equipment maintenance, and provides a solid foundation for the next development of the entire rail transit direction; [0003] Such as Figure 6 As shown, the central computer room of the urban rail cloud platform includes a safety production network, such as bearer signal ATS system, automatic fare collection system, integrated monitoring system, access control...
