Study on Effect of Power Source Frequency to Temperature-rise Test of High-voltage Switchgear and Controlgear

通过有限元法对简易模型进行了不同频率下的温升仿真分析,从理论上论证了试验电源频率对温升的影响。完成了不同高压开关设备在不同频率下的温升比对试验。通过对试验数据统计分析,初步得出了各高压开关设备不同频率下温升稳定值间的量化关系。

This work carried out the temperature rise simulation analysis of the simple model at different frequencies via finite element method,and theoretically demonstrated the influence of test power frequency on temperature rise.It then performed actual temperature-rise comparison test of different high-voltage switchgear and controlgear at different frequencies,and preliminarily proposed the quantitative dependence of temperature-rise stability values on varied frequency with respect to each switch apparatus according to the test data statistics.
