Zhigulevskaya HPP, Part 2

Zhigulevskaya HPP, Part 2

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.

Zhigulevskaya HPP, Part 2

On the roof of the machinery hall. This is a huge 700-meter-long building!

Zhigulevskaya HPP, Part 2

Each cable is as thick as an arm! And the sound it makes, is very impressing!

Zhigulevskaya HPP, Part 2

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.

Zhigulevskaya HPP, Part 2

This is a very old trash screen. You can’t imagine how disgusting its smell is!

Zhigulevskaya HPP, Part 2

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.

These screens prevent water from entering the hydraulic unit. At this station they use free water pressure force to fulfill some tasks.

Zhigulevskaya HPP, Part 2

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.

Zhigulevskaya HPP, Part 2

Everything is giant at this station! This lighter is for you to see the real size of this screw.

Another giant metal thing.

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.

Zhigulevskaya HPP, Part 2

That stairsace leads into the hydraulic unit.

Zhigulevskaya HPP, Part 2

Control equipment.

Zhigulevskaya HPP, Part 2

Chopper switchers. It’s very hot there despite working conditioners.

Zhigulevskaya HPP, Part 2

Current goes from hydraulic units to transformers through these copper wires.

Zhigulevskaya HPP, Part 2

Perhaps, they go there.

Zhigulevskaya HPP, Part 2

Old chopper switchers.

This is one of the hydraulic units. There are 20 of them at the station.

Hydraulic turbine, Zhigulevskaya HPP.

Zhigulevskaya HPP, Part 2

A shaft connecting the turbine with a rotor wheel.

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.

Zhigulevskaya HPP, Part 2

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.

Zhigulevskaya HPP, Part 2

Permitted pressure is 25 atmospheres.

This is a no entry sign.

Zhigulevskaya HPP, Part 2

When they were building the dam, they made these cavities deliberately, to save some concrete.

Zhigulevskaya HPP, Part 2

It’s hot and quiet there and the air is very humid.

Zhigulevskaya HPP, Part 2

These pumps pump out water which percolates throught the concrete.

Zhigulevskaya HPP, Part 2

Hermetic doors.

Zhigulevskaya HPP, Part 2

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.

Zhigulevskaya HPP, Part 2

It feels weird when you stand here and realize that there are 52 meters of water above you!

Zhigulevskaya HPP, Part 2

Rusty chains.

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.

Zhigulevskaya HPP, Part 2

The plant has its own museum and this is one of the exhibits – a diver.

The dam.

Zhigulevskaya HPP, Part 2

More cranes.

Zhigulevskaya HPP, Part 2

In this photo you see the water level difference.

Zhigulevskaya HPP, Part 2

Right now they are reconstructing the dam.

Zhigulevskaya HPP, Part 2

These are rails for cranes to move along.

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.

In the distance you see an anemometer.

Zhigulevskaya HPP, Part 2

A beautiful scenery with wires. They are everywhere, so without them the hydroelectric power plant would not be a plant.

  1. Thats an interesting place. I cant even find pictures of the biggest one here in my own country.

    Does he really mean “Old chopper switchers” or should that be copper switches.

    Reply
    • no- chopper switches is correct
      they are an oil filled bath (so yes petrohof- correct) with the switch contacts (usually gold) immersed in the oil to `quench’ any sparks
      In air, when turning off a very high voltage/current supply, it can actually start an arc (like when using a electric welder) that can draw out to several feet in the right conditions
      these arent circuit breakers normally (they will have a large coil box attached to the contact arm if they are being used as breakers- these appear to be a manually operated switch for some reason (or the current sensor box is missing)

      fasinating to see the West German Seimens industrial processor in use there along with the mixture of meters being used in the control room

  2. “A super-smart computer.”. It’s not super-smart, it’s just an operating panel. I was impressed how 60’s technology is harmonically integrated with modern industrial control systems.
