A, in addition to the manufacturer for a new transformer factory test, the installation site should be completed and put into operation before hanging core examination; the same overhaul. (Short-distance transport bumps may be no time, but should be pressure and other tests) power transformers B, when more than half of transformer outage, the insulation resistance should be measured, and make oil pressure test. C, the transformer primary input voltage should be ≤5 closing plenary impact test, overhaul of ≤3 times and should load operation 24h without exception, in order to gradually put into the load; and do the record. The purpose is to check the dielectric strength of the transformer can withstand the rated voltage or the operation occurred in operation voltage, but also to the mechanical strength and protection actions assessment of the reliability of the transformer. D, new clothes and overhauled transformer insulation resistance, at the same temperature, should not be less than 70% of the factory test value. E, in order to improve the utilization of the transformer, reduce variable loss, the transformer load current 75 to 85% of rated current is more reasonable. Distribution power transformer is a static electrical device, it is used to a certain value of the AC voltage (current) into the same frequency as another one or several different values ??of voltage (current) devices. When the primary winding through a alternating current, alternating magnetic flux generated alternating magnetic flux through the core role of the AC electromotive force is induced in the secondary winding. Secondary induction level and a secondary winding turns EMF much information, that is, the voltage is proportional to the size and number of turns. The main role is the transmission power, and therefore, the rated capacity is its main parameters. Rated capacity is a manifestation of the power of conventional values, it is the characterization of the size of the transfer of power to kVA or MVA said that when the transformer rated voltage is applied, according to which, under specified conditions to determine the limits of temperature rise does not exceed the rated current. Now more energy-efficient power transformer amorphous alloy core distribution transformers, its biggest advantage is that the value of extra-low load loss. Ultimately able to ensure load loss value, it is the core issue throughout the design process to be considered. When the product structural arrangement, in addition to considering the amorphous alloy core itself from external forces, but at the same time must reasonably accurate in the calculation of selected parameters of amorphous alloys. Larger domestic production of power transformer manufacturers have TBEA Luoyang stars cattle.
