摘　　要：本文在断路器的热场分析基础上,构建了其散热制冷系统。实验结果表明,机柜制冷机组运行时,各个静触头温度迅速降低,其工作温度在52℃-62 ℃,温升完全满足国家标准中规定的小于65 K要求。本文设计的制冷系统,增加了断路器在湿热环境下的运行可靠性。Based on the analysis of circuit breaker cabinet thermal field, the refrigerating system has been constructed accordingly. The experiment result showed that, the various static contacts operating temperature is rapidly decreased to the range of 52 ℃-62 ℃ as the cabinet refrigeration unit operates, and the static contacts temperature rise fully meets the requirements of the national standard of less than 65 K. The operation reliability of the circuit breaker in hot and humid environment is increased by the proposed refrigerating system.
