IEC 60077-2:2017 is an international standard that defines the requirements for control and protection systems for electrically propelled railway vehicles. This standard provides guidance on various aspects of control and protection systems, including their design, installation, testing, and maintenance.
Design and Installation
The design and installation of control and protection systems play a crucial role in ensuring the safe and reliable operation of electrically propelled railway vehicles. The standard specifies the necessary requirements for the design and layout of these systems, including considerations for electrical safety, mechanical integration, and environmental conditions.
One of the key aspects of design and installation is the selection of appropriate components and equipment. The standard provides guidelines for selecting suitable devices, such as circuit breakers, contactors, and relays, to ensure their compatibility with the overall system. It also addresses issues related to electromagnetic compatibility and insulation coordination.
Testing and Maintenance
Regular testing and maintenance are essential for the continued performance and safety of control and protection systems. The standard outlines the procedures and requirements for conducting routine inspections, functional tests, and preventive maintenance activities.
Testing includes verifying the proper functioning of various components and subsystems, as well as checking for any abnormalities or deviations from the expected performance. Maintenance activities involve regular cleaning, lubrication, adjustments, and replacement of worn-out parts.
The importance of documentation is emphasized in the standard, as it facilitates traceability, troubleshooting, and knowledge transfer. Detailed records of design specifications, installation procedures, test results, and maintenance activities should be maintained throughout the lifespan of the control and protection systems.
