T/CPSS 1006-2022 Design specification for selective protection of low-voltage DC power system of ships
Basic Information
Scope
Scope: This document specifies the design method of selective protection for short-circuit faults in low-voltage DC power systems of ships. This document is applicable to the protection measures taken for low-voltage DC power systems (below 1000V) of ships with floating ground wiring such as bipolar and unipolar symmetrical wiring, due to thermal or overcurrent conditions; Main technical content: This standard proposes the selective protection principles of mainstream protection equipment and topological structures in low-voltage DC systems, forming a set of relatively universal design standards for selective protection of low-voltage DC power systems of ships. The implementation of this requirement will fill the gap in international standards for selective protection design of DC power systems of ships and help establish China's leading position in the field of DC distribution
