These look like motor/generator sets to me. I used similar ones back in the 70's to produce DC power for huge carbon arc lamps in an old drive-in theater. I agree these could have provided field excitation for the generator, but before the generator started, what power ran the mo/gen?
Hz... as in Hertz. House electricity is 120V @ 60 Hz. Presumably, they were trying to keep very close track on thier frequency output. I worked at an off-shore ligthhouse once... the throttle of the diesel generator controlled the output AC frequency.
I'm not absolutely sure what these are, but exciters is my best guess. I doubt they are phase convertors as a generating station will already have three phase power available. Nice pictures!
It looks like the ID number's on the batteries are written in black magic marker on duct tape. These must have been installed towards the end of the power plant's life.
These devices convert 3 pahse AC to dc. Looking at the device the section in the front is a dc generator, and the section in the rear is a 3 pahse AC motor. The whole machine could be replaved whtih a bridge rectifier {a solid state device] that you could hold in the palm of your hand.
The tubular objects at the top - center and right - center are fuses, with the blade end they would be 100 + amp capacity. These are a rebuildable fuse, meaning when it blows it can be taken apart and the fuse element replaced. We have some of these around the shop where i work, but from what i understand they are no longer available as the wrong capacity element can be put into the wrong housing, creating a risk of fire or eqipment damage.
One of the absolute kewlest movies ever, huh? And that gorgeous Brigitte Helm! The film was made in 1926 and was supposed to take place in the year 2026, which is kinda freaky the closer we get. http://www.geocities.c...itte_helm_images.htm
This is not a condenser. It is part of the boiler assembly. Those are not tubes sticking out, they are tie rods for the missing plates.The rods supported the plates from bulging outward while under pressure. You can see from the picture titled Cross Sectioned, that this unit sits directly below the turbine. And from the picture titled Scale that this is the backend of the boiler.
These pictures are wonderful. It is rather sad this little piece of history has been allowed to degrade into it's current state.
