绝缘结构是电机的心脏,通常所说的电机发生故障,绝大部分是由于绝缘结构损坏所引起,因此电机行业对于绝缘结构的选择和制作都非常重视。为了使广大读者对电机绝缘技术能有一个较全面的了解,本刊约请了上海电器科学研究所的俞树人、吴秀月俩位同志为这一专题撰写文稿,拟深入浅出地介绍电机绝缘技术中常用的材料、绝缘结构的组成,绝缘处理工艺,绝缘结构试验等内容,大致分四次在本刊连载刊完。希望广大读者读后提出意见和要求,以便我们改进,谢谢。 Insulation structure is the heart of the motor, the so-called motor failure, most of the insulation structure is caused due to damage, so the motor industry for the selection of insulation structure and production are very seriously. In order to enable readers to have a more comprehensive understanding of motor insulation technology, this issue has invited Yu Shuren and Wu Xiuyue from Shanghai Electrical Apparatus Research Institute to write contributions for this topic. It is intended to introduce the commonly used materials in motor insulation technology , The composition of the insulation structure, insulation treatment process, insulation structure test content, roughly four times published in the serial. Hope that the majority of readers read comments and requirements, so that we can improve, thank you.
