Long-term heating and excessive temperature rise will significantly affect the electrical and insulation performance of electric power equipment, causing the potential security risk. In this paper, the temperature rise situation under normal operation of a 12-kV medium voltage switchgear is studied through modeling and simulation method. First, in the simulation analysis of the whole switchgear, based...
In this paper, we analyzed the electromagnetic disturbance of plusmn 500 kV valve tower by electromagnetic field calculating software, which based on the instantaneous method, but also including the space electromagnetic field and the radio interference level. And then, we compare the radiated electric field strength with the relevant standards, its comparison with observed result is being studied...
According to the diversity of transient electromagnetic quantity, typical waveforms and spectrums of switching operation are got in transient disturbance; then, the disturbance characteristic of time and frequency domain are analyzed. Mainly the distribution probability and frequency statistic of characteristic parameter are analyzed. Drawing up probability graph of time-domain and envelope diagram...
