Power on the Tram Museum.
600 V DC
The Tram Museum in Skjoldnæsholm, by Ringsted, are using power 600 V direct current, for their trams. The power is for both the 300 m long one-meter gauge tramway and for the 1,5 km standard gauge tramway. There is going Trams from the earlier Danish tram cities Copenhagen, Odense and Århus, and from European tram cities. The home site for The Tram Museum is

The way of power

Transformer Beheind the rectifier is the Transformers 1 and 2. The income power is 3-phase 10kV, 50Hz. This is from a external cable, and The Tram Museum has a connection to this cable. The power is not only direct current power for the trams, but even 230/400 50 Hz v alternating current for own use.

The power is transformed to 600 v direct current.

Switcher is switching out by 1600 amp.

Connection The power is going out to the catenary.

Knotmasts The masts are from the the area NESA's supplies. They are cotted of their old foundations, so they are shorter, but long enough for the catenary. They can bear a pujlle from all sides, they are strong on both sides.

Mast width lattice The sdandard mast can only be pulled to the long side. The lefst side of the mast is total vertical, but the right side is sloping. In this way the mast kan take a pull to right. The boom, whish bear the cables, are for different towns in Germany. The catenary is six meters over the tracks.

The trams have different collectors:

Lyre bow has been used in Odense.

Normal Pantograph is on trams from Århus and many other european cities.

One leg pantograph This pantograph belongs a newer tram from Oslo, but now runs in Skjoldnæsholm.

Trolley pole has been used on Copenhagen trams. It is not gliding, but has a wheel.

The wheel on a trolley pole.

In the curves have the Tram Muesum two catenaries beside each other. The extra catenary is to keep the gliding pantograph under the catenary.

Cross The meter-gauged and the standard gauged tranways have their own special power supplies, but the same voltage. The must be isolated for each other, where the cables i crossing.

Switch point When a tram is changing its track, the trolley pole had to follow on the new cable. Therefore the cable division must be a peace after the track devision.

Even on a overcasted day, there is life on the Tram Museum.
