Scope

Scope: This document specifies the use environment and conditions, classification and composition, technical parameters, technical requirements, type test and factory test, nameplate, packaging, transportation and storage requirements of DC disconnect switches for urban rail transit overhead contact lines. This document is applicable to the manufacture and inspection of DC disconnect switches for urban rail transit with a nominal voltage of 750V and 1500V, as well as their actuating mechanisms and auxiliary equipment. Main technical content: As a key electrical equipment in the power supply system, DC disconnect switches are used to realize the energization and de-energization of the overhead contact line. The inlet side of the switch is connected to the DC feeder cabinet of the traction substation via a cable, and the outlet side is connected to the overhead contact line via a cable. The standardization and reliability of equipment selection are crucial, and it is necessary to develop a plan in the design stage to ensure standardized construction and installation, as well as convenient operation, maintenance, and repair. Currently, there are no industry standards specifically for DC disconnect switches for urban rail transit in China, so it is very necessary to fill the gap in DC disconnect switch standards to guide the construction of rail transit projects.
