A century of electric power development history
15,000 yuan. Blades are an industry with greater certainty, greater market capacity and a clear profit model among wind energy components. As the tight supply and demand situation eases, the wind power blade industry will also undergo transformation, from ahe melee between a group of heroes to a struggle for hegemony between a few powerful players. redesign and integration. The 68-meter large power generation fan blade costs 15,000 yuan. The large industrial fan blade is machined from high-quality 1.5mm thick high-density aluminum alloy motherboard used in the aviation industry and is integrated with laser, bending and welding end to end. mussels.
A century of history of electricity development:
A century of history of electricity development in the 19th century. In 1800, Volta invented the first chemical battery. In 1831, people started. to obtain a direct electric current. Faraday Manufacturing In 1866, Siemens manufactured the first self-excited generator using electromagnets. In 1870, Gram manufactured the self-excited ring-armature motor to power factory arc lamps. built at Gare du Nordin Paris.
Using DC power to provide nearby lighting. In 1879, San Francisco built the world's first commercial power plant, with two generators and a total of 22 arc lamps. In the same year, experimental arc street lights were installed in France and the United States. In 1879, Edison invented the incandescent lamp. In 1881, the United Kingdom built the world's first small hydroelectric station.
Edison built the world's first small hydroelectric station in New York. The first formal power plant in 1882, Frenchman Deppler demonstrated a direct current generator with a voltage of 1500~2000V at the Munich Expo. In 1884, the British manufactured the first steam turbine. In 1885, they made an alternating current generator. Machines and transformers were used to establish the first alte power transmission systemrnative in Great Barrington, Massachusetts, in March 1886. The supply side was increased to 3000 V and the voltage was reduced to 500 V at the receiving end over a distance of 1.2 km.
, demonstrating the superiority of AC transmission. In 1891, Germany installed the first 100 kW three-phase alternator at the Laufen power station, which transported electricity to Frankfurt via the first three-phase transmission line. 1894. Liagara Falls Hydroelectric Power Station. In 1896, three-phase transmission of electricity was adopted to send it to Buffalo, a distance of 35 km. This ends the 1880 debate over the superiority of AC and DC. ?
A century of development of electrical energy in the 20th century. In 1903, the Westinghouse Electric Company installed the first 5,000 kW steam turbine generator, marking the beginning of general steam turbine units. In 1916, the United States built the first 90 km (132 km) linee V In 1922, the United States built the first 220 kV line in California.
After World War II, the United States manufactured and put into service 30, 50, 100, 115, and 1.3 million kilowatt turbine generators in 1955, 1960, 1963, respectively. , 1970 and 1973? In 1954, Sweden? A 380 kV line was built, using 2 separate conductors, over a distance of 960 km, to carry electricity from the Harspranget hydroelectric power station in the Arctic Circle to southern Sweden.
In 1954, the former Soviet Union built its first nuclear power plant. In 1973, France built a 1.2 million kW nuclear reactor. In 1964, the United States built its first 500 kV transmission line. Canada built its first 765 kV alternating current transmission line. In 1965, the Soviet Union built the first ±400 kV direct current transmission line over 470 km, trancarrying 750,000 kilowatts of electricity. In 1970, the United States built a 1,330 km ±400 kV direct current transmission line, transmitting 1.44 million kilowatts. of electricity. In 1989, the Soviet Union built the first 1,900 km power transmission line with a maximum voltage of 1,150 kV.

The importance of a century of electricity: < /p>
Integrating ideological, authoritative, documentary, visual and popular sciences, it is a documentary film that reflects the century-old history of China's electric power development. It is also a television teaching material for building a harmonious socialist society and conservation economy. oriented society. It is also a main thematic work that realizes the spiritual education of patriotism and fierce struggle. At the same time, the film offers the public a window to understand China's electrical industry and its development history. It is an ideal teaching material for vocational teaching and traditional education of electricity industry employees. It can also strengthen employee cohesion and strengthen employee cohesion. morale and stimulate employee enthusiasm for the cultural construction of electric power enterprises. Pride, responsibility and mission play an important role.
