摘　　要：在6篇文献的基础上综述了新型的超高压发电机(powerformer)的特点。这种发电机不同于常规发电机,其绝缘介质是交联聚乙烯,即采用交联聚乙烯绝缘高压电缆作为绕组线。绕组电缆由导体、内半导电屏蔽层、绝缘层和外半导电屏蔽层构成。新型超高压发电机可以直接产生高电压,省去了升压变压器,可直接将电能输入电网。分析了新型发电机的冷却系统和其他优缺点,同时展望了新型发电机的广阔前景。This paper introduces a new type EHV generator,Powerformer.The main difference between a Powerformer and a traditional generator is the insulation.The Powerformer is made of EHV or HV XLPE cable.The Powerformer generates HV/EHV avoiding an ascending transformer and the energy generated by the Powerformer is input the grid directly.It also describes the cooling system,the advanˉtages and disadvantages of the Powerformer.The future development of the new type generator is prospected.
