History of the profession - electrician

History of the profession - electrician Where did it all start? Much in the history of electrical engineering is associated with the name of T. Edison (1847-1931). He is the author of approximately 1000 inventions in the field of electrical engineering. Edison improved the incandescent lamp and built the world's first public power plant (1882).

History of the profession - electrician Stock telegraph (original name stock ticker) - the first telegraph apparatus for broadcasting stock quotes, was invented by Thomas Edison in 1870. Quote information was printed on ordinary paper tape by punching holes on the tape, producing a ticking sound. For his truly revolutionary work in the development of trading in stock markets, Edison received, at that time, 40 thousand dollars.

History of the profession - electrician Edison's first patented incandescent lamp with carbon filament

History of the profession - electrician In 1880, the French physicist M. Depres announced the possibility of transmitting electricity through wires. He also built the first power transmission line. In 1882, at the invitation and with the assistance of Oscar Miller, he built an experimental power transmission line for demonstration at the Munich Electrotechnical Exhibition. On this 57 km long Miesbach - Munich line, direct current from a Gram generator, driven by a steam engine, with a voltage of 1400 to 2000 V was transmitted via telegraph wire to a similar generator, which acted as an electric motor. The load for the engine installed in the exhibition pavilion was a pump that raised water to a height of several meters, from where it fell in the form of a waterfall. The installation power was about 1.5 kW.

History of the profession - electrician Subsequently, Despres built several power lines in France, of which the most important was the Creil - Paris direct current line, 56 km long and with a voltage of 5000-6000 V with an efficiency of about 45%. The results he achieved lost their relevance with the advent of alternating current lines. Nevertheless, his experiments showed the possibility of practical implementation of this task, which is so important for technology. The dental electric drill belongs to Depre's inventions.

History of the profession - electrician The creation of economical DC machines and the initial steps in the development of electric lighting and electric drives could not have made fundamental changes in production practice if another cornerstone problem of the electric power industry had not been solved - the transmission of electrical energy over a distance. In the 70-80s of the XIX century. this problem became relevant in connection with the emergence of large industrial enterprises. The need itself for methods of transmitting energy to consumers remote from sources of mechanical energy existed and was somehow resolved long before the appearance of the first power plants. Thus, by means of wire ropes it was possible to achieve a transmission range of up to 120 m, and with the installation of intermediate blocks - up to 5 km. Repeated attempts were made to use compressed air and hydraulic pressure to transmit energy, but neither principle could form the basis for providing mechanical energy to factory production on a large scale. The problem of transmitting electrical energy over a distance The hopes of inventors turned to a new type of energy - electricity.

History of the profession - electrician Scientists continue to work on the problem of using electricity for lighting and other needs. The famous “electric candle” by P. N. Yablochkov was the first consumer of current. To install wires and cables, people who understood electricity were needed. This is how the profession of electrician appeared. However, with the advent of more and more different electrical devices and the increasing complexity of electrical engineering, the profession is branching into many specialties: electrician, equipment repair electrician (depending on specialization), electrician, electrical technician, electrician, etc. Today, there are several dozen electrical specialties.
