I have just started taking another set of turbines down, same pretty much as last lot. On looking at some pics i took while taking the first lot down, I discover that they dont seem to work at all like the 3 page manual said they do!
the manual offers no real information, but from discussions with other people who have had turbines, the following is a basic run down of how we saw it.
Blades turn a generator and Dc goes down into the panel where some kind of inverter changed it to three phase, from there through to a three phase meter and out onto the grid...
Some the things I actually know about these particular turbines. the generator has both a weak mechanical and some kind of electric brake on it, none of the break cables were thicker than telephone cable. The optimum output voltage was 600V DC. The generator was controlled speed wise via motor control system made by ABB systems, the same kind of units use to control and monitor conveyor belt motors.
The pics I have are not good, but I might have a chance to take better ones if the panels havnt been completely dismantled. The real question I need answering is, how was the 600V DC change to 3 phase? The unit I assumed was the inverter i am pretty sure is actually a motor control unit.
Why do I need to know? Well despite the brakes being stuck on (they wont be needed anyhow), the units are around 5.6KW each and I have three of them. I will have the panels etc shortly, and the idea is to try and match them to a PTO type set up for off site generation. Anyway take a look at the pics I have so far and see what you think. The company who made them has gone bust, the company who took over will offer no help whatsoever and have been agressive to save the least.
The generator itself is between the red lines, I can take better pics now the shrouds are off and the coupling. They are really heavy coming in around 480Kg each, The green box is part of this 'warner brake' system, i dont think i actually need the brake for what we want to do.
The red arrow shows what i was told was the inverter, a close up dosnt show much so again I can take more pics.
Sorry the rest look corrupted! I will try and take some more. Any thoughts so far? The sticker on the large ABB units talks about a max 0f 500V AC, however in the other panels are large stickers warning 600VDC?
