Industry Background

Solution Overview

It is applicable to electrified railways, urban rail transit systems, or city rail transit lines powered by AC 27.5 kV, including mainline catenary systems, station yards, and depots (EMU depots). The solution enables automatic grounding operations during catenary system maintenance, remote visual monitoring, online voltage detection, operational safety management and control, safety interlocking, and closed-loop management of work processes. While ensuring safety, it significantly improves the efficiency of grounding operations and safety measure deployments, thereby extending the effective maintenance time for catenary systems.

Solution Advantages

Automated grounding operations

Automated grounding operations

It achieves central, station-level, and local three-level grounding control, supporting multiple operation modes such as electric and manual, as well as multi-point parallel grounding operations, significantly enhancing operational efficiency.

Comprehensive safety assurance

Comprehensive safety assurance

It ensures comprehensive safety protection for grounding operations through technical measures such as anti-misoperation logic verification, voltage detection and grounding interlock, disconnector and grounding switch interlock, commendatory interlocking, access control, safety warnings, and emergency management.

Visualized operation supervision

Visualized operation supervision

Supervisors can monitor on-site conditions remotely in real-time by monitoring the catenary system grounding, live state in real-time, and remote video monitoring of grounding switch status and operational processes.

Networked process control

Networked process control

Combining grounding operations with work tickets, operation tickets, and dispatch orders ensures consistency between operating equipment and tasks, building a networked closed-loop process control system.
