Construction Technology Of Integration Of Four Electrical Systems Of High Speed Railway

Four Electrical systems of high-speed railway includes four systems as communication, signaling, electricity and electrification. They are the core to realize speed and capability target value of high speed railway, ensure safe and reliable operation of train. Four electrical system integration technology is the theory of system integration in railway construction in the new century the most important technology in the application, it covers the system structure, interface management, construction management, comprehensive testing, maintenance, training, evaluation of RAMS, emc, environmental conditions, evaluation and so on eight aspects. Among them, the high-speed railway four electrical system integration construction technology is the longest high-speed rail construction technology in the application cycle, face the most complex environment, the application level of technology, most is one of the core technology of high-speed railway construction.In this paper, the author study in sd railway engineering construction technology on the basis of "four power", the system studied the domestic and foreign scholars about the engineering application of system integration, system integration theory and engineering application examples of "four electrical system integration mode of writing, combined with the author in the south of guang high iron and xiang-gui high iron" four electrical system integration with practical experience in construction, using system theory, cybernetics and synergy theory knowledge, from the view of system optimization, the collaborative control introduced the integrated construction mode of "four electrical system integration construction technology.This paper based on the high-speed railway construction as the carrier, introduced in the key construction technology of detail the communication line, equipment installation commissioning, tower foundation construction, GSM-R debugging, signal systems installed cable engineering of track circuit, speed rail, transponder installation, indoor engineering, electric power system in the cable line, box-type electric power equipment installation, cable head production, main transformer electrification system of transportation and installation, the erection of contact-line, elastic cable installation, positioning device, isolating switch and lightning arrester installation etc, and mainly included technological process and quality control.In this paper, the four electrical system integration construction technology is an important part of high speed railway engineering, is an important part of the study of high iron four electric construction technology, constantly practice summarizes and induces optimization for the next stage, and finally formed a complete system integration technology system in the seeds.
