Abstract

The paper deals with machines able to operate in high temperature (HT°) environments. Most of standard machines are made with enameled wires insulated with a thin polymer layer. With the best availiable enameled wires, the organic nature the winding insulation limits the operating temperature to about 280°C at the hottest point. Therefore, standard machines cannot be used in the hot environments of specific applications such as deep drilling in petroleum industry, geothermal equipment or near aircraft turbines. Recent studies show that an inorganic insulation technology, made without any polymer, can push this thermal limit up to 500°C. After presenting an overview of the available HT° insulation technologies, the paper details the possible topologies of HT° machines and their limits.
高温机械拓扑结构
本文讨论了能够在高温(HT°)环境中运行的机器。大多数标准机器是用漆包线制成的,用一层薄薄的聚合物层绝缘。使用最好的漆包线,绕组绝缘的有机性质将工作温度限制在最高点约280°C。因此,标准机器不能用于特定应用的高温环境,例如石油工业的深钻,地热设备或飞机涡轮机附近。最近的研究表明,一种不含任何聚合物的无机绝缘技术可以将这一温度限制提高到500°C。在概述了可用的高温保温技术后,本文详细介绍了高温保温机的可能拓扑结构及其限制。
