WATERFALL

• This is the Ezaro´s waterfall that it´s in the Corcubion´s estuary. The Xalla´s river finishes making this waterfall. It´s open because lasts days rained a lot. When it´s open they lose 100m3/s. it´s got 100m of high. They used it since 100 years ago to feed some furnaces that use silicio

How does it work?

As this river bring a lot of water, they maked a dam( the dam of pindo).

The water has got a potencial energy to 200m of high. When it fall produce a cinetic energy that move the turbine producing mechanic energy and it moves the alternator that it changes the mechanic energy in electric energy.

The machines of the first building work with 100.000 kw

FIRST BUILDING

• There are 2 vertical turbines of 50.000 kw each one.

• It built in 1992

DISYUNTOR OF GAS

• This is a “disyuntor of gas”. It can be of oil or gas. Without this the current can´t flow for the lines. It´s a security measures.

TRANSFORMERS AUXILIARIES

• In each one go in 13000V and go out 70000V. In the factory of Dumbría the value of voltage changes in 220V

THREE PHASES TRANFORMERS

REFRIGERATOR FULL OF OIL

SECOND BUILDING

• There is a horizontal turbine of 10000kw.

• It is 100 years old

Horizontal turbineHorizontal turbine

Parts of turbine: Parts of turbine: stimulation( to make stimulation( to make turn the rotor) turn the rotor) alternator ( to change alternator ( to change the mechanic energy the mechanic energy into electric energy) into electric energy) turbine ( part mobile, turbine ( part mobile, it moves the axis that it moves the axis that get until the get until the stimulation). It is 8 stimulation). It is 8 years oldyears old

ALTERNATOR

• It has got 110v and provided direct current to the poles. It produce altern current. We give tension of 110V to the magnets. It creates a magnetic field that produce a altern current to 6000A

CONTROL PANELS

THIRD BUILDING

• There are two vertical turbines of 12000kw and one of 6000kw

• It is 50 years old

TURBINETURBINE

EMPLOYERS

There are 15 employers of maintenance the total of the factory are 30 and the total of the company are 260.

The employers work 8 hours by day
