Product Overview: The three-phase dry-type transformer for high-voltage excitation is used for the hydroelectric power system and so on. It can convert electrical energy under high voltage, accurately provide excitation for generators. Specific Introduction: 1.Advantage of High-permeability: High-permeability silicon steel sheets optimize the magnetic circuit and reduce the excitation loss. During high-voltage excitation, they can efficiently guide magnetic flux, ensure stable operation, improve the utilization rate of electrical energy and stabilize the excitation of generators. 2.Protection of Vacuum Impregnation: Vacuum impregnation ensures electrical isolation. Under high voltage, it can prevent insulation breakdown, resist moisture and dust, protect the high-voltage excitation circuit. High insulation enhances the anti-interference ability and reduces the risk of failures. 3.Precise High-voltage Regulation: It can precisely regulate the high-voltage output. With the changes of the power grid and generator working conditions, it can make accurate adjustments to stabilize the electrical energy of generators under high-voltage excitation, ensure the stability of the frequency and voltage of the power grid and protect the safety of the system. Operation Environment A) Altitude: Not exceeding 1000m, shall be derating used if above 1000m; B) Ambient Temperature: -25℃~55℃. C) Relative Humidity: ≤95%; D) As to the installation site, to make sure no bad effect on transformer insulation, chemical deposition, dust, and other explosive or erosive medium. E) The supply voltage approximates sinusoidal wave, and the three-phase voltage is relatively balanced.
