n.自耦變壓器
For the large capacity cage electric motor, it cannot use the "star - angle" to start, but can use autotransformer (compensator) to start. 對于較大容量的鼠籠電動機,不能用“星一角”起動方式時,可采用自耦變壓器(補償器)進行降壓起動。
Operational features and load characteristics of autotransformer common winding under different work conditions are analyzed in detail. 針對電網內耦自變壓器不同運行工況,詳細分析了耦自變壓器公共繞組的運行特性及其負載特性。
They are autotransformer low-voltage starter,high-voltage transducer soft-starter and a dedicated transformer for the motor starting directly on line. 過去,大型及超大型電動機的起動不外乎有三種方法:自耦變壓器減壓起動,獨立變壓器供電直接全壓起動及高壓變頻器軟起動。
The alternating current was sent to the input end of the autotransformer and pressure-rise circuit after adjusting voltage. 交流電源送入自耦調壓器輸入端,調壓后送至升壓電路。
