摘要
介绍了一种可用于高电压的新型环保干式变压器的结构组成.这种变压器的结构特点是采用高压电力电缆作为变压器绕组,省去了绝缘油.通过对其温升、电场分布、暂态电压特性、短路阻抗、负载损耗等基本特性的分析认为,与传统变压器相比,这种变压器具有电压等级高、容量大、阻燃不爆、环保性能好、线路损耗小、绝缘强度高、结构简单等优点.
The structure of a new type of green dry-type transformer for high voltage is introduced. High-voltage cable is used as the winding of this type of transformer, and therefore insulating oil is not needed. The analyses of its basic characteristics such as temperature rise, electric field distribution, transient voltage behavior, short-circuit impedance and load loss show that, compared with the traditional transformers, this type of transformer has the advantages of high voltage class, greater capacity, frame retardation, less environment impact, lower line losses, high insulating strength, simple structure and so on.
