一些地区电力供应紧张,电压波动较大。为了保证生产的正常进行,许多厂矿企业都在自己的变压器上加装有载调压装置。目前常用的有载调压装置有串变有载调压和有载分接调压开关两种形式。无论哪一种,从汲取能源的角度来看,都是在改变受电端的阻抗,以便从电网中汲取所需的能量。在电网电压低于额定值的情况下,通过 In some areas, power supply is tight and the voltage fluctuates. In order to ensure the normal production, many factories and mines in their own transformers installed on-load voltage regulator. At present, the commonly used on-load voltage regulator has a series of variable load on-load tap-changer and on-load tap-changer in two forms. Either way, from an energy-taking point of view, it is all about changing the impedance of the receiving end in order to draw the energy needed from the grid. Pass the grid voltage below the rated value
