摘　　要：针对KYN28A-12铠装移开式开关设备常规产品无法满足大型工矿企业、大型电厂等重大负荷要求的问题,开发了5000A-50kA铠装移开式交流开关设备。通过结构和散热通道改进,该设备满足了开关柜绝缘性能、温升、机械寿命、短时耐受电流、关合和开断能力等技术参数要求。In view of the problem that the KYN28A-12 mobile armored AC switchgear cannot meet the major load requirements in large industrial and mining enterprises and large power plants,the 5000A-50kA mobile armored AC switchgear was developed.Through the improvement of the structure and heat dissipation channel,the equipment met the requirements of the technical parameters such as the insulation performance of switchgear,temperature rise,mechanical life,short-time withstand current and closing and breaking capacity etc.
