摘　　要：核电厂属于特殊应用领域,近年来,为了确保核电厂配套设备质量,国家相关部门及核电用户正对核电厂关键电气设备进行严格监管。1E级低压抽出式成套开关柜安装于核电厂核岛厂房内,是负责对核电厂安全系统供电的重要设备。研究了1E级低压抽出式成套开关柜设计上应采取措施,提出了降低产品温升,提高开关柜抗地震性能及其耐内部故障电弧性能等方案,能够满足核电相关标准及核电厂用户的要求。Nuclear power plant belongs to the special application field, In recent years,In order to ensure the quality of nuclear power plant auxiliary equipment,the relevant departmants of the state and the user of the nuclera power is strict supervision the key electrical equipment. The class 1E low voltage withdrawable switchgear installed in the nuclear power island plant,is responsible for the equipment for power supply of safety ststem in the nuclear power plant. Class 1E low voltage withdrawable switchgear cabinet design should take measures to reduce the product temperature, improve the anti earthquake performance and internal fault arc resistance performance of switch cabinet, meet the users of nuclear power related standards and requirements of the plant.
