DC RELAY PROTECTION & CONTROL

Overview

The DC Relay Protection Measurement and Control Device (DCR150 Series) is designed for protection, measurement, and control of urban rail transit DC traction power supply systems. It provides reliable protection and monitoring for key DC system components, supporting safe, stable, and efficient operation of rail transit power supply networks.

Protected systems include DC incoming lines, DC outgoing lines, feeder circuits, frame leakage systems, rail potential, and DC system components.

Core functions include DC relay protection, measurement, control, protection monitoring, DC system monitoring, and traction power supply protection.

DC traction power support covers DC overhead contact lines, all voltage levels, urban rail DC systems, traction substation applications, and rail transit power supply networks.

Key benefits include enhanced DC system protection, improved power supply reliability, safer rail transit operation, stable traction power supply, and comprehensive DC monitoring.
