Wanli Yangtze River First Dam: A stunning world 40 years ago, 40 years later, wisdom "reborn"!

"Wanli Yangtze River First Dam -the two sets of single -machine capacity of Gezhouba Hydropower Station with a capacity of 170 MW is a water wheel generator set. It is successful in trial operation. The diameter reaches 11.3 meters. "

September 30, 1981

Broadcast of this news

Causes the world to be shocked

It even attracted questions from Western media

It is difficult for them to believe

China at that time

There is such a high level of design and manufacturing

Now, 40 years have passed

The water wheel generator set that was shocked by the world

It has become a member of the Yangtze River "veteran"

The "age of retirement"

A sense of technology full of technology

Make it with a new and smarter look

Stepping on the feet again

Continue to run 40 years, the wisdom of the water wheel generator set is "new"

Gezhouba Hydropower Station is located in Yichang City, Hubei Province

It is the first large hydropower station on the dry flow of the Yangtze River

The name of the first dam in the Yangtze River

Including 22 axis rotary paddle -type water rotor generator sets

The capacity of 2 machine groups is 170 MW

(Referred to as "big machine")

The diameter of the rotor is 11.3 meters, and it is still the world's largest

19 units of the single -machine single -machine capacity 125 MW

(Referred to as "small machine")

1 single -machine single -machine capacity 20 MW

Two of them, 6 small machines

Developed by Oriental Electric Electric Motor

Two major aircraft are separated from

It was launched in July 1981 and December 1981

By 2021, it has been running for nearly 40 years

The life of the theoretical operation life

To ensure that the crew continues to run safely, stable and efficient operation

Gezhouba Power Station launched the project renovation project

Oriental Electric is responsible

2 major aircraft update transformation equipment development work

Gezhouba update and transformation project water guide mechanism pre -installed top lid hanging

In Gezhouba Daji Updated Reconstruction

Oriental motor is based on the intelligent analysis diagnosis system independently developed

Developed Gezhouba large -scale axial flow rotary paddle crew

Holographic monitoring and intelligent diagnostic system

The system is based on the existing standard configuration

More than 200 sensor measuring points are added

Realize units of holographic monitoring

For the first time in the industry, the PXI -based bus

Virtual instrument collection equipment collection unit running parameters

Realize multiple physical quantities, large quantities,

Data collection of high frequency, real -time synchronization

The first unit water guide institution passed the acceptance and acceptance

July 16th

Gezhouba Power Station 170,000 kilowatt axis circulation paddle type

Water wheel generator set update and reconstruction project

The first unit successfully passed the 72 -hour trial operation

Commercial transportation

The largest diameter in the world

Axial flow transit water wheel generator crew rejuvenates new wisdom appearance

In 40 years, the spirit of technology for a long time

In the 1970s

my country began the construction of Gezhouba Hydropower Station

Oriental Electric took out 170,000 kilowatt large machine solutions

Whether it is a stand -alone capacity or a diameter

There are no precedents worldwide

At that time, Oriental Electric was just the "small head" in the industry

But to challenge giant units that have not been created abroad

In the eyes of many people

not

At the design seminar of the Gezhouba Water Rice Generation Unit held by the original machine department

Someone wants to overthrow the design plan of the Oriental Electric Machine

Some experts even asserted

"This will be a bunch of scrap iron thrown in the Yangtze River"

Facing doubt

Oriental Electric is based on strong calculation results

Adhere to the "big machine" design plan

And issue a response

If there is nothing abroad, it cannot be available in China

What we explore is the way that the predecessors have not walked

Relying on the simple and selfless dedication and love for the motherland

Oriental Electric has made the biggest innovation vitality

Whether the cold winter is still hot or hot

In the factory building, welding flowers splash and roar of the machine

A pair of rough big hands

It's like wearing Hua Najin, it's not bad

1500 days and nights

"Small head" depends on the strong map

I have completed the challenge of motivation and persistence

After 40 years of development

The development level of my country's power generation equipment has achieved a huge leap from iterative

In the age when the computer is not even hand -shaken

Older generation of central enterprise builders use abacus and calculation ruler

Completed again and again

Today, Oriental Electric

Successfully developed the Three Gorges, Xiludu, Baihetan, etc.

Giant Water Rice Generation Unit

Realize the leap development of "following", "combined" to "running"

Building the industry's first stator unmanned workshop

Have multiple academicians and expert workstations

The output and scale of power generation equipment have ranked first in the industry for many years

It has become a vanguard enterprise that has been developed by the world's hydropower equipment

The beginning of the heart is uncomfortable, and it is stable and far away

Equipment China, amazing world

Gezhouba, the heavy weapon of the country

Central enterprise continues to write legends
