Quality Control of Materials and Components for 1 000 kV Transformers and Reactors

摘要: 为控制1 000 kV变压器/高抗主要原材料组部件的质量,概述了特高压交流工程中1 000 kV变压器/高抗主要原材料组部件包括电磁线、硅钢片、绝缘件、套管的使用情况,总结了其在入厂检验、生产制造过程中出现的典型质量问题,提出了针对性的质量管控措施及技术要求,可有效地避免有质量问题的原材料组部件使用在设备中,从而提高设备的质量稳定性。

Abstract: In order to control the quality of main materials and components which are used for 1 000 kV transformers and reactors, this paper describes the applications of these materials and components such as electromagnetic wire, silicon steel sheet, insulation material and high-voltage bushing and summarizes the typical quality problems that occur during inspection and manufacturing. The pertinent quality control method and technical requirements are proposed, which will effectively avoid the use of materials and components that have quality problems, thus enhancing the quality stability of transformer and reactor.
