Product Overview:
The three-phase dry-type transformer for low-voltage excitation is applied in the hydroelectric power system for low-voltage excitation and so on. It can accurately regulate the voltage to ensure the stable operation of generators and the conversion and distribution of electric power, adapting to the complex working conditions of hydroelectric power plants.
Specific Introduction:
1.High-permeability Silicon Steel Sheets:
It can reduce magnetic hysteresis loss and improve the conversion efficiency of electrical energy. During low-voltage excitation, it responds quickly, precisely controls the excitation current and stabilizes the output voltage, adapting to load changes.
2.Overall Vacuum Impregnation:
It provides high electrical isolation to prevent leakage and short circuits. In a humid environment, it ensures the reliability of insulation, enhances the anti-interference ability and guarantees the safe operation.
3.Wide-range Voltage Regulation:
It can adjust the voltage within a wide range according to the working conditions of hydroelectric power plants. Under different water heads and loads, it can accurately output voltage to maintain the power quality of the power grid and help generators operate efficiently.
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.
