摘　　要：对国内外复合绝缘子发生脆断的主要原因进行了总结，归纳了主要研究者对发生芯棒脆断的研究成果，其主要原因有均压环装设不周、端部密封不良、芯棒表面微裂纹等，以及针对芯棒脆断原因提出的相应改进措施。在此基础上，结合复合绝缘子在设计、制造、安装和维护的过程中，探讨了未来复合绝缘子可能脆断的研究方向。The primary causes of brittle fracture of composite insulator cores in domestic and international the paper is analyzed. Summarizes research achievements of the main researchers of cause of brittle fracture, such as unreasonable grading ring design or incompact end sealing or surface micro- crack of cores etc. cause of brittle fracture of composite insulator, and put forward the corresponding improvement measures for cause of brittle fracture And on this basis,combining with the process of composite insulator in design,manufacture,installation and maintenance, some future research directions of brittle fracture of composite insulator are discussed.
