高低高变频调速系统中组合式变压器设计

The Design of the Integral Type Transformer in the High-low-high Variable-frequency Speed Regulation System

在高低高变频调速系统中,研发设计了降压变压器和升压变压器,器身放于同一油箱中,成为一台油浸式组合式变压器,经投入运行,效果良好,值得在变频调速系统中推广。

In the high-low-high variable-frequency speed regulation system, the step-down transformer and step-up trans- former were designed. An oil-immersed integral type transformer was formed by putting the two transformers in the same oil tank. Practical application proved that this method had good effectiveness, and was worthy to be popularized in the variablefrequency speed regulation system.
