Study on Assembly Scheme of Main Electrical substation of Rail Transit
In recent years the construction of rail transit has developed rapidly,but restricted by land resources and other factors,its main electrical substation is often located in urban areas,so the application of modular assembly technology is particularly important.This paper simplifies the on-site docking and wiring workload by dividing the transportation units of primary equipment and selecting prefabricated cable terminals,achieving"plug and play"of primary equipment.By a-dopting a unified equipment foundation and a unified foundation size module,standardized and shaped steel molds are ap-plied to concrete preparation and improve process level.This may help in facilitating the promotion of on-site mechanized construction and electrical installation,the reduction of labor input and on-site safety risks,and improvement of project quality,and can provide useful information for future practices in construction and operation of rail transit main substa-tions.
