众所周知,当间隙产生火花放电时,在电流和电压的波形中皆可观察到其瞬时值以很高的频率在振荡,如图1所示。该图(A)中上部为间隙放电时的电压波形,下部为放电时的电流波形;图(B)上部为间隙电弧,放电皆有时的电压波形,下部为其相应的电流波形;图(C)上部为间隙污染时的电压波形,下部为其相应电流;图(D)上部为间隙短路时的电压波形,
It is well-known that when a sparkover occurs in the gap, the instantaneous value of the current and voltage waveforms can be observed to oscillate at a very high frequency, as shown in Figure 1. The upper part of Fig. (A) shows the voltage waveform when the gap discharges, and the lower part shows the current waveform during the discharge. The upper part of Fig. (B) shows the voltage waveform when the gap arc and the discharge are both, and the lower part shows the corresponding current waveform. ) The upper part is the voltage waveform when the gap is polluted, the lower part is its corresponding current; The upper part of Fig. (D) is the voltage waveform when the gap is short-circuited,
