IEC 61992-6-2020 PDF

Full title and description

St IEC 61992-6-2020 — Railway applications — Fixed installations — DC switchgear — Part 6: DC switchgear assemblies. This entry typically refers to the consolidated edition incorporating Amendment 2 published in 2020, providing requirements and guidance for the design, construction and verification of DC switchgear assemblies used in fixed railway installations.

Abstract

IEC 61992-6 specifies requirements for DC switchgear assemblies for use in fixed installations of traction (railway) systems. The consolidated document reflects the original 2006 publication together with subsequent amendments up to 2020, and covers functional, constructional and testing aspects needed to ensure safe, reliable DC switchgear assemblies in traction applications.

Scope

This part of IEC 61992 applies to DC switchgear assemblies intended for fixed railway installations with nominal DC voltages (the IEC 61992 series addresses fixed installations supplying guided public transport). It sets out requirements for assembly construction, ratings, protective devices, coordination, documentation and testing to ensure safe operation within DC traction environments.

Key topics and requirements

• Definition and classification of DC switchgear assemblies for fixed railway installations.
• Electrical ratings, insulation and clearances appropriate to DC traction systems.
• Requirements for protective devices, switching components and interlocks.
• Verification and type/production testing procedures for assemblies.
• Marking, documentation and information to be supplied with assemblies (ratings, wiring diagrams, maintenance instructions).
• Requirements for mechanical construction, ventilation and accessibility for maintenance.

Typical use and users

Primary users include manufacturers of DC switchgear assemblies, railway system integrators, specification and procurement engineers, testing and certification laboratories, and maintenance departments of rail infrastructure operators who specify or verify compliance of fixed DC switchgear used in traction power substations and associated installations.

Related standards
