power transformer - large in size device that is used to transmit electric power from the main power over long distances.Most often, it has two windings (maybe more) that convert the voltage and make it suitable for use in homes, businesses and other institutions.For this device has a variable magnetic field.
power transformer can step-down (distributes the energy flow) and increases (transmit power over long distances), depending on how it should "redo" voltage.It should be noted that before the fall of the current station in place domestic use, it is converted several times.
The principle of operation of the unit is based on the phenomenon of mutual induction.It involved both windings.At first, when it arrives at the electricity generated alternating magnetic flux, which generates an electromotive force in the second winding.If the coil is connected to the second receiver of energy, it begins to flow through the current.The voltage has to be converted.
should be noted that the power transformer
As for the windings, they often have a cylindrical shape.Near the most magnetic should be a lower voltage, as it is easier to isolate.Between the windings have to be insulating gasket.
power transformer device is large enough to install that requires time, strength and caution.Doing this should be qualified electricians who are authorized to perform such work.First of all, the unit is delivered to the installation site.For this purpose, a large truck or a platform on the rails.In the territory, which will do all the work should be organized for the possibility of the entrance and the work of loading and transport and mounting hardware.
installation of power transformers should be made in accordance with the requirements of safety regulations.The site must be equipped with all necessary equipment, as well as all necessary equipment for fire fighting.On the job site must be installed telephone connection.Next, you need to ensure good lighting installation site.
If all the preparations are made, the need to fully explore the power transformers for bad set of parts, cracks or other damage.Also check the input using the test voltage.
After installation of the unit must be carefully checked.If, during the test were observed problems, they must be removed.If the defects can not be eliminated on the spot, then the device should be sent to production, where it will be carefully inspected and repaired.
