Zhigulevskaya Hydroelectric Power Plant has alredy been the topic of one of our previous articles, but it’s so big and great that you’ll never explore it all. So, let’s continue the tour!
In the picture: one of its cranes.
On the roof of the machinery hall. This is a huge 700-meter-long building!
Each cable is as thick as an arm! And the sound it makes, is very impressing!
Wires are located very high above the roof as a precausion measure.
This is a tail-water view. You can see some people down there, who are netting the fish deafened by the turbine. The HPP has a special cutter which they use to scare fish away but it’s not always helpful.
A head water view. These are screens which trap trash.
Fish and trash swimming together.
This is a very old trash screen. You can’t imagine how disgusting its smell is!
They have a special crane for lifting and lowering the screens and collecting the garbage. Its elevation capacity is 250 ton.
This is a trash elevating device.
Another view of the machinery hall.
These screens prevent water from entering the hydraulic unit. At this station they use free water pressure force to fulfill some tasks.
This is the machinery hall. In the foreground you see some components of the turbine.
This is a similar part of the turbine but this time this is a view from the inside.
Everything is giant at this station! This lighter is for you to see the real size of this screw.
Another giant metal thing.
Zhigulevskaya HPP in section.
This handle turns off the power plant in case of emergency. They say that at one of the excursions, someone accidentally turned it and the whole HPP stopped!
The hydraulic unit.
In fact is it very big too. In the previous picture there is just its upper part.
That stairsace leads into the hydraulic unit.
Chopper switchers. It’s very hot there despite working conditioners.
Current goes from hydraulic units to transformers through these copper wires.
Perhaps, they go there.
Old chopper switchers.
This is one of the hydraulic units. There are 20 of them at the station.
Hydraulic turbine, Zhigulevskaya HPP.
A shaft connecting the turbine with a rotor wheel.
This man accompanies visitors of the HPP.
Through this manhole, you can see the rotor wheel which is the rotor of the generator.
Those red things are brakes to stop the unit.
Another hydraulic unit.
Hydraulic turbine. Made by Leningrad Factory of Metal Production built in the name of Stalin, 1956.
To make it clear for you (top-down): cross piece, turbine cover, distributor, spiral case, rotor wheel.
An oil pressure sensor.
Permitted pressure is 25 atmospheres.
A super-smart computer.
Another view of the machinery hall.
A crane inside of the machinery hall.
This is a no entry sign.
When they were building the dam, they made these cavities deliberately, to save some concrete.
It’s hot and quiet there and the air is very humid.
These pumps pump out water which percolates throught the concrete.
There are two footways at the plant: dry and moist. In the dry footway there is equipment, serving the pumps pumping out water, which gathers in the moist one.
It feels weird when you stand here and realize that there are 52 meters of water above you!
The control center.
They say that the level of the head water and tail water changes really fast. Once, some people came here to swim near the dam and left their car at the concrete which was dry. Several minutes later they saw their car drifting away in the direction of Askrakhan.
The plant has its own museum and this is one of the exhibits – a diver.
In this photo you see the water level difference.
Right now they are reconstructing the dam.
These are rails for cranes to move along.
Inside of the iron crane.
This is what the crane operator sees from his workplace when he has a break.
Otherwise, he sees this.
For those interested in this job, here’s a general view of the cabin.
Mechanisms situated inside of the crane.
An overfall dam.
In the distance you see an anemometer.
A beautiful scenery with wires. They are everywhere, so without them the hydroelectric power plant would not be a plant.
