Due to factors such as power source location and environment, some stations Built in the plateau area, it has the characteristics of high altitude and high voltage level. Compared with the same type of electrical equipment at low altitude, it is different in structure, height, length and quality. There are obvious differences in the surface, which are reflected in being taller, longer, heavier and more flexible, and more stringent requirements are placed on the seismic performance of equipment in high seismic intensity areas. GB/T 42558 "High-altitude Converter Station" is specially formulated to provide guidance for the seismic design, modeling calculation, testing and evaluation of the electrical equipment of this type of converter station. "Seismic Technology for Electrical Equipment in Stations". GB/T 42558 is intended to consist of six parts. --- Part 1.Guidelines for seismic testing and evaluation. The purpose is to establish the electrical system for converter stations in high seismic intensity areas in plateaus. General requirements and evaluation principles for equipment seismic testing. --- Part 2.Seismic design specifications. The purpose is to specify the overall requirements for seismic design of electrical equipment for converter stations in plateaus, Seismic design of equipment, seismic design of equipment coupling connections, and seismic structural measures for equipment. --- Part 3.Seismic isolation design specifications. The purpose is to specify the design calculation of seismic isolation and seismic isolation of electrical equipment in converter stations for plateau use Methods, selection of shock absorbing and isolation devices, and construction requirements. --- Part 4.Equipment selection specification. The purpose is to guide the selection of electrical equipment in plateau converter stations and improve the resistance of electrical equipment. Shock performance. --- Part 5.Equipment operation and maintenance guidelines. The purpose is to help operators better monitor and maintain electrical equipment in high-altitude converter stations. It provides a standard basis for inspection, evaluation, maintenance and other work. --- Part 6.Technical specifications for earthquake monitoring systems.
