Aps Ground Level Power Supply System

Maybe the complete system should be grounded there at the power supply and maybe that is a terrible idea.

Aps ground level power supply system.

The power is picked up by contact shoes located under the vehicle on the trams central bogie. Fuji provides the best solution for every customer s operating service requirements. Aps helps preserve the beauty of the urban environment while guaranteeing the same performance as overhead contact lines. For dc power requirements we offer a broad range of highly efficient and compact programmable ac dc power supplies for bench or rack mount use ranging from 3000 watts to 100 s of kilo watts.

The aps 5vp series of high power programmable dc loads addresses the growing for high speed dynamic transient load testing of large batteries. The aps was designed to provide less frequent stops and easier maintenance. It was invented for the bordeaux tramway tramway de bordeaux which was constructed from 2000 and opened in 2003. Auxiliary power supply system fuji electric provides a high efficiency and economical auxiliary power supply system aps for railcars used in public transportation.

It was invented for the bordeaux tramway which was constructed from 2000 and opened in 2003. Fuji s aps will be satisfied with various requirement. Supporting five different built in battery test profiles and power levels up to 60kw per chassis the 5vp series is unmatched for these applications. Alstom s aps ground level power supply system is a proven alternative with equivalent performance which is currently operating in seven cities on three continents and offers safe reliable power to trams whether in short catenary free sections or along the entire line.

I ve concluded that grounding the dc of my power supply tested for leakage current is safe reasonable also my next bench supply will be a re purposed psu which will by default be grounded internally anyway. But in isolated projects for deployment i will. Currently this is the only place it is used but there were and are proposals to install it elsewhere. The conductive segments are activated only when fully covered by the tram ensuring total safety for pedestrians and other road users.

With aps power is supplied to the tram through a segmented street level power rail. Ground level power supply is or has been used primarily for aesthetic reasons. Ground level power supply systems date back to the beginning of electric tramways with some of the earliest such systems using conduit current collection. A wide selection of power levels and voltage ranges to choose from.

Ground level power supply also known as surface current collection and alimentation par le sol aps which literally means feeding via the ground is a modern method of third rail electrical pick up for street trams. Ground level power supply also known as surface current collection or alimentation par le sol is a concept and group of technologies whereby electric trams collect electric power at ground level instead of more common overhead lines. Large capacity aps for dc cars with 3 level inverter. Until 2011 this was the only place it was used with.

The aps frequency changer product range is available in power levels from 500 va to 180 kva single and three phase output. Fuji auxiliary power supply line up.
