摘　　要：针对万能式断路器在不同频率(50 Hz和60 Hz)、相同电流下温升存在一定差异的情况,研究了万能式断路器温升与工作频率的关系。通过相关温升试验结果的比对分析,得出了不同频率下温升的补偿系数。试验结果表明补偿系数具有可参考性,可为相关人员进行万能式断路器的温升检测提供参考。Aiming at the problem that the temperature rise of the air circuit breaker is different under the same current at different frequencies(50 Hz and 60 Hz),the relationship between the temperature rise and the working frequency of the air circuit breaker is studied.Compensation coefficients for temperature rise at different frequencies are obtained by comparing and analyzing relevant temperature rise test results.The test results show that the compensation coefficient can be referenced,which can provide a reference for the relevant personnel to detect the temperature rise of the aircircuit breaker.
