6 Zhigulevskaya HPP, Part 2

Zhigulevskaya HPP, Part 2

Posted on November 3, 2011 by


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!

    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.

    • petrohof says:

      i think so too. the old one pictured looks like an oil filled switch.

    • dap says:

      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

    “Another giant metal thing.” Appreciate the info, ER…

    “Rusty chains.” Rust never sleeps, ER…

    “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.
