The device on the wall is a key interlock system (we used an interlock system from a company called Kirk). The way it worked was that it forced you to make switching moves in a certain order. For us, we would rack out a 4kv breaker to capture a key, then you took that key to the device on the wall, and that one key would unlock a series of keys which unlocked doors to our percipitator. The key interlock systems were used to force you to perform operations in certain orders.
The dial in the center right side with the two light bulbs underneath is the syncrascope. This was used to help synchronize the generator to the system before closing the breaker to connect the generator to the electrical system. You need to match voltage, frequency and then synchronize. This always fascinated me that all the generators in the system have to be synchronized. I saw one main breaker closed in by accident and we were not up to speed or synchronized, this immediately brought the generator up to 3600 rpm and synchronized. This is a violent action and everything in the control room bounce up,,,,, kind of like an earth quake, every person, coffee cup, piece of paper, and chair bounce about 3". We tripped and had to perform a generator tear down. We got lucky and only knocked the insulating blocks out of the generator. It could have been much worse, I've seen pictures of generator shafts bent and the machine beating itself to death.
These lights are normally DC power, hence the battery banks,,,,, somewhere there is a battery charger that is still in service. The lights appear to only be indication. The switches are not control switches that I have ever seen. The control switches are usually larger.
All power plant use dc power for controls, this is what is used to open or close many of the breakers in the plant. In our plant we used 125V DC, and we had banks of batteries to provide back-up DC for controls and emergency equipment (DC lube oil pumps, DC back-up seal oil pumps).
The device sitting on the floor, is a seal oil system. Generators are filled with hydrogen to reduce windage since hydrogen is less dense than air. The hydrogen is circulated in the generator by a fan built into the generator rotor. The gas flow circulates thru coolers to maintain the gas temperature and keep the generator cool. The hydrogen pressure in the generators where I worked maintained 60 psi of hydrogen. The seal oil system monitored the generator pressure and maintained the seal oil pressure 12 psi above gas pressure. The seal oil is injected at the generator labyrinth seals to seal the stationary to rotating surfaces of the generator.
I worked in a coal fired power plant for over thirty years, so I may be able to help you identify some of the images. This appears to be the brushes, this is where the field excitation is placed on the rotor. As more power is needed the excitation is increased. The turbine and generator maintain a constant speed without regard to power output.
I worked in a coal fired power plant for over thirty years. I may be able to help identify some of these images. This is a low pressure turbine, and a condenser underneath. Normal steam flow is from the boiler to the high pressure turbine, then the exhaust from the high pressure turbine is returned to the boiler, known as cold reheat, the steam is then reheated and sent to an intermediate turbine, then the exhaust from the intermediate turbine is exhausted to the low pressure turbine. The exhaust from the low pressure turbine is sent to the condenser to restart the condensate flow to the boiler. The condensing of steam creates a vacuum, the vacuum in the condenser is usually at 28" Hg.
That is interesting to know... But these type contraptions tend to show in my dreams... Bathroom areas with dim lighting... To which I wake up and my bladder is full... So eerie these things...
Quite a classic that kind of got taken completely out of context for a wee bit there... But it was found in a nuthouse and seems to be insane prattle until you place it in its right context... Good one though all the same...
Interesting... Those circles are probably used for a poleball game, the one where the ball is on a rope which is secured to the top of the pole and whacked around. Can't think of the proper name of it... Still good snap though...
Wow... The Number and a Beauty Shop... Which is where those ladies defiantly claiming to be demonesses or flat-out succubi go for the latest hairstyles from the Land that Lies to the South of Heaven... Nice one indeed...
Looks scratched into the wood indeed, but a fork? Unless it was snuck in here, yes, but there is no establishing shot for the actual size of said scratches. But I am staying with fork. Looks also they were interrupted or caught... Interesting pic though...
