Let’s continue our excursion around the Zhigulevskaya HPP.
The tremendous energy produced by the plant requires proper “care”. That’s why near every hydroelectric generator there is a substation providing such “care”.
These are vacuum circuit breakers. Everyone remembers from school that if you place 2 conductors with high voltage close to each other, there will be formed an electric arc between them. The circuit breakers are used to prevent its forming.
Obsolete equipment is actively reconstructed. These are, for example, old oil switches.
Some complicated mechanism.
A very interesting place. A generator is above us. The shaft of a turbine is in front of us. The blades of a wicket gate through which tons of water pass are below.
A cylinder (every generator has 4 of them) which is responsible for the angle of the blades.
Hydroelectric generator â„–17. The drive of the blades is not yet upgraded. That’s why instead of 4 cylinders, 2 huge running on oil are used.
Here you can pop out of the window and get that thrilling feeling when a huge multi-ton mechanism is rotating above your head.
This hydroelectric generator is unique.
It’s the only one at the plant having such a plate. “Leningrad Metal Plant Named After Stalin”. The surname of Stalin wasn’t rubbed out.
The engine hall.
The view from the crane.
To feel the scope of all this, let us note that the thickness of the wall on the right is 4 meters.
