摘　　要：针对常见的电抗器开裂绝缘缺陷展开研究,在参考国家标准的基础上研制了电抗器绝缘试验平台,对不同类型的铝线材料、不同开裂程度的电抗器进行了匝间绝缘试验,结果发现由BBYL9材料制造的电抗器在开裂情况下击穿电压要高于其他材料的电抗器。In this paper,the common cracking insulation defects of reactors are studied.On the basis of reference to national standards,a reactor insulation test platform is developed.Interturn insulation tests are carried out for different types of alu minium wire materials and reactors with different cracking degrees.It is found that the breakdown voltage of the reactor made of BBYL9 material is higher than that of reactors made of other materials in the case of cracking.
