配电变压器低压侧额定电压为400/231伏。但在一些修理、试验、科研中,往往需要多种高于其额定电压者。升压器(调压器)虽可输出很高电压,但允许电流有限;升流器电流虽大,但电压受限制。在不少情况下用配变异相连接可取得多种高于额定值的电压,输出一般调压,升流设备不能达到的参数。我们曾这样用作另序电流烘燥变压器的电源。不久前,一台水轮发机静子驱油干燥时,由两台配变输出的600V,200A 的电气参数;顺利地突破设备卡脖子的
Distribution transformer low voltage side of the rated voltage of 400/231 volts. But in some repair, test, scientific research, often require a variety of higher than its rated voltage. Although the booster (regulator) can output a very high voltage, but allows limited current; current converter is large, but the voltage is limited. In many cases with variable phase connection can be obtained a variety of higher than the rated voltage, the output voltage regulator, the device can not reach the parameters. We used to do this as a power source for a separate current-drying transformer. Not long ago, when a water turbine stator oil displacement drying, by the two with variable output 600V, 200A electrical parameters; smooth break through the neck of the device card
