Matching Design and Experimental Research on Refrigerating System of Circuit Breaker Cabinet
摘要
Abstract
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 oC~62 oC 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.关键词
