In the 18th century, the industry 1.0 process, which started with the industrial revolution, ie the mechanization of production and renewable energy sources such as steam, water and wind as the main energy source of production, has been replaced by Electrical Energy with Industry 2.0 at the end of a short time.
In today's world where Industry 5.0 is used, there is a need for a irreversible and increasing trend. While the need for energy throughout the world increases, the economic obligation of energy use and most importantly, the C02 release, which resulted in climate change, increases. These problems lead both governments and end users around the world to the use of energy as well as the use of renewable energy resources.
Distribution of electrical energy according to the installed power in Turkey; 31.4 is hydraulic energy, 28.6 percent of natural gas, 22.4 percent coal, 8.1 percent wind, 6.2 percent of the sun, 1.6 percent of geothermal sources are provided*. Despite the rapidly increasing renewable energy sources, sun, geothermal, wind energy cleaner, economical, harmless and sustainable energy sources, fossil fuel use is still in the first place.
to produce electricity from solar energy
Electricity from solar energy offered by nature to us is provided by photovoltaic batteries, which are semiconductory substances. These batteries consist of the (negative) semiconductor material which is added to the N type in the upper layer and the P -type (positive) semiconductor material in the lower layer. The photons from the solar energy panel hit the layer of the N type -added semiconductor material in the solar panel and transfer its energy to the electrons, while the energized electrons get rid of the atoms and form a structural electric field. Thus, there is a potential difference between the N type and P -type semiconductors, and as a result, electrical current is formed.
DC The current in the photovoltaic unit is converted to AC current through the inverter and transmitted to the load. In this process, DC switching and protection products should be used to protect and control the DC current until it reaches the inverter. As in AC systems, all elements that need to work in the structure of solar power plants, which are a DC system, should be designed and produced in a structure in accordance with the technology and international standards that can guarantee maximum operation safety and maximum protection.
SOCIETY ELECTRICAL DC Systems
Since the protection and control of DC systems does not pass through the DC voltage 0 point, it is more difficult than AC systems. The protection elements used in AC systems cannot provide the desired protection when used in DC systems. Sigma DC circuit breakers perfectly protect the electrical system against overload currents and short circuit currents, while produced under CE quality assurance in accordance with the related international standards.
Sigma Electricity by adopting maximum safety and protection by adopting DC systems specially developed DC automatic insurance 1, 2, 4 -pole 6ka and 10ka cutting capacities with high electrical and mechanical life.
Sigma DC Compact switches are produced as the thermal setting field 250A up to 250a 3 and 4 poles.
