BS EN 61287-1:2014

What is BS EN 61287-1 - Power converters installed on board rolling stock about?  

BS EN 61287 is a European standard that discusses power converters installed on board rolling stock for railways application. BS EN 61287-1 is the first part of series that outlines terminology, service conditions, general characteristics and test methods of electronic power converters onboard of rolling stock to ensure safety while operating power converters. BS EN 61287-1 applies to power electronic converters mounted on board railway rolling stock and intended for supplying traction circuits and circuits of power vehicles, coaches, and trailers  

The application of BS EN 61287-1 extends as far as possible to all other traction vehicles, including trolleybuses. 
BS EN 61287-1 covers the complete converter assembly together with its mounting arrangements containing: 

• Semiconductor device assemblies 
• Integrated cooling systems  
• Integrated components like inductors, capacitors, transformers, resistors, contactors, switches  
• Semiconductor drive units (SDU) and related sensors  
• Incorporated protection circuits  

The following types of power sources are taken into consideration under BS EN 61287-1  

• AC contact lines  
• DC contact lines 
• On-board supplies such as generators, batteries, and other electric power sources  

Note: BS EN 61287-1 excludes converters that provide the electronic control supply for semiconductor drive units (SDU) and other supplies relevant to the converter operation such as sensors.
