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