The turbine is spinning.

The Electrosila plant and its research center are one.

Laboratory.

Scientific research and design developments are in one continuous cycle with production.

Volkhovskaya power plant.

Hydro generators at the power plant are manufactured at the Electrosila plant.

All four hydrogenerators have tripled the service life of such machines.

Construction of the Sayano-Shushenskaya HPP.

The world's largest power plant.

The hydro generators created at the Electrosila plant for this power plant are the most powerful in the world.

Power lines.

The high unit capacity of these machines gives great economic benefits.

Operating costs are reduced, the construction of a power plant becomes cheaper.

Confirmation of this is the Krasnoyarsk hydroelectric power station.

The costs of its construction were fully paid off even before the last generator was started.

Comparison of different generator models in the context.

Certificates of registration of scientific discoveries carried out by designers and employees of the scientific center at the Electrosila plant.

Patents for these discoveries in various countries of the world.

Test benches.

It was believed that with an increase in the power of hydro generators, their reliability sharply decreases.

The problem was solved with the help of water cooling.

The layout of the generator with thermosetting insulation shown in the section.

But this insulation also keeps the heat in the running machine and the generator overheats.

They decided to cool the stator with water.

A graph showing how cooling affects material savings.

The reliability of the machines is not reduced.

Contacts and brushes of turbo generators quickly wore out, they had to be replaced frequently.

In the new design, the direct excitation current began to be supplied directly from the rod of the current line through a monolithic copper wedge.

The brushless exciter practically does not wear out and the reliability of the turbo generator in operation increases dramatically.

This was confirmed by tests on a special stand.

The only stand in the world where tests of large machines are carried out in the workload mode.

Thus, the operation of all components of the machine is checked even before its operation.

The generator is finally brought up within 2-3 weeks.

Previously, it took up to a year and a half at the power plant.

Turbo generators account for 3/4 of the total electricity generation in the world.

To create a turbo generator with a record capacity of 1200,000 kW at the Electrosila plant.

The most powerful machine has also become the most reliable.

Turbo generator assemblies.

Unique machines for the production of generators.

A milling machine on which the slots of the rotors are drilled with such jewelry precision that then the rotor will practically have no vibration in operation.

The line of aggregate machines for processing turbine generator parts combined eight operations and all of them are performed in one pass.

Sheets of stator iron.

In the stamping shop, with high productivity, the accuracy of products is always stable.

The narrow specialization of the workshops made it possible to introduce automation into such processes as precise plasma cutting of thick steel sheets, welding of large parts in an electroslag bath.

Labor-intensive parts of a complex profile are manufactured on machines of the CNC machining center type.

Such a center performs up to 10 operations per installation.

The processing accuracy is maintained at all transitions.

Errors occur when moving parts from machine to machine.

At the factory, these duties are performed by robots, they link the entire technological chain of this site into one automatic line.

Alternation of frames with details of the hydrogenerator.

Capsule generators of the Electrosila plant operate on small rivers.

Other generators work on rivers with high water pressure.

Feedback has been established with all the countries in which the plant's generators operate.

Computer center.

Magnetic media.

It receives information about the operation of machines.

After processing on a computer, the information is used in the design of new generators.

The next generation of electric machines is already being born in the laboratories and workshops of the Electrosila plant.
