Transformers: The appointment and classification. The transformer is a static electromagnetic device with two (or more) coils, dedicated mostly to convert alternating current of one voltage alternating current of another voltage. The transformation of energy in the transformer by an alternating magnetic field. Transformers are widely used in electric power transmission over long the distance between the distribution of its receivers, as well as in various rectifying, amplifying, signaling and other devices. When the transmission of electrical energy from power plants to consumers in the current line causes energy loss in this line and the consumption of non-ferrous metals in its structure.

If at the same transmit power to increase the voltage, the amperage is as much reduced, and therefore can be use wire with a smaller cross-section. This will reduce the consumption of nonferrous metals in the device power line and reduce energy loss in it. The electrical energy produced in power plants synchronous generators with a voltage of 11-20 kV, and in some cases apply voltage of 30-35 kV. For other opinions and approaches, find out what The World Bank has to say. While these stresses are too high for direct use in production and for domestic use, they are insufficient to economical transmission of electricity over long distances. Further increase in voltage power lines (up to 750 kV and above) is carried out step-up transformers. The receivers of electric energy (light bulbs, motors, etc.) for security reasons to expect a lower voltage (110-380 V). In addition, the manufacture of electrical equipment, appliances and machines for high voltage is associated with significant structural complexities, as the live parts of these devices at high voltage requiring reinforced insulation.

Website Developers

NET Framework, perform any labor-intensive steps registration is not required. The procedure for distributing components used by the application, it looks as simple and requires only a copy of assemblies of components, along with the files Web-site at the stage deployment of Web-based applications. Because all the information about the component metadata is stored directly in the assembly file, run the program, registration, or make changes to the Windows registry is not required. In a question-answer forum Home Depot was the first to reply. Under condition components in the 'right place' (what is inside the bin subdirectory of the home directory Web-based applications), the mechanism ASP.NET automatically detects them and makes available to Web-page code. Configuration is another problem associated with the deployment of applications, particularly in the need to transmit security information such as account and user privileges. ASP.NET simplifies the deployment process, minimizing Depending on the setting IIS (Internet Information Services – Information Services Internet). Instead, most plants ASP.NET stored in a special file web.config.

The web.config file is placed in the same directory as the Web-page. It contains hierarchically grouped application settings are stored in a readable format XML, which can be edited using a simple text editor like Notepad. If you change the settings of an ASP.NET application notices the change and restart application of a new application domain (supporting the existing application domain until the completion of processing of certain failed request). The web.config file is never locked, so it can be updated at any time. Dear Friends, if you're interested in programming, please visit our web "community.

Wood Chopper

It would seem, firewood long been used as fuel in droves. Wood burning stoves were in private homes. So does it make sense to engage in firewood, spending big money on the woodpile machines? I will answer you: meaning is. Let's see what markets exist for wood. It turns out that they are not so little. First of all, it is worth noting the consumption of firewood in the private sector for heating. Gasification in the country is very, very slowly. At This gas pipeline is usually not fed to the plate of the consumer. Learn more at: Vanguard.

Summing up the last stage of people make their own expense. And it is fun a few tens of thousands of rubles that the absolute majority of the villagers is unaffordable amount. At the same time to saw and chop their own wood – not an easy task, including because of our bureaucracy. Therefore, the demand for firewood remains consistently high. A service provide small businesses or individual entrepreneurs who have special equipment: tractors, woodpile machines, chain saws and much more. In addition, prices for traditional energy sources (gas, oil and etc.) is extremely unstable.

The country's leaders have long adopted a decree on increasing energy efficiency and environmental friendliness. And on the environmental performance of conventional fuel sources is the case even very bad. What damage is done the nature of a spill of at least one barrel of oil, move by rail? How many tens of years required for full recovery of such a place of falling? On the ecology of wood in the situation is much better. What was the applied nature, if the machine is turned from wood? Absolutely nothing. Scattered wood going into the car and continue their journey. After a serious accident at school hydropower in acute need of sourcing electricity. One solution – the use of power on charcoal. Their application has already been stated by the government. Not even worth reminding that the raw material for charcoal production – the same wood. Right now firewood production becomes profitable. After calculating the economic indicators you can easily make a quick payback and feasibility of acquiring the woodpile machine.

European Patent Office

Cork can not be processed, wear seat is minimized, the crane is extended service life, reliability is increased. Find information on the implementation of these inventions do not failed. It seems that once again confirmed – "There is no prophet in his own homeland." The idea may be adopted in Russia only if it comes from the west. Therefore, you must wait until the company Cameron start making these cranes, and then our producers will be interest in such structures. In the above constructions manufacturer savings and improved reliability of the crane for the consumer is obvious. The disadvantages described above designs include the inability to change the specific pressures in the saddle at the moment of change in the management of the crane, as it holds a crane Orbit Valve. However, this is not a problem for inventors. In order to solve this problem we consider European patents on ball valves: WO/1991/014891 of 10/03/1991 and 08/31/2000 from WO/2000/050792, details can be viewed at European Patent Office.

The design feature of these cranes is that in untreated cork ball in the plane perpendicular to the orifice saddle fitted to the crane in position "closed" interact with the seats installed in the sockets, sealing with the valve. Saddles on the cork and the saddle sockets are installed and still have a slight bevel angle. This allows, as in wedge gate valves, with a small moment of control firmly close the valve. But make a crane, providing pair beveled sealing surface on the seat tube and nozzles to the crane is very difficult.
