High Voltage Spherical-Gap Discharge Switch, High Voltage Pulse Generation Circuit and High Voltage Discharge Switching Method

摘要

The high voltage gap discharge switch has a pair of spherical electrodes 1, a projection 2, and a blower 5. As shown in FIG. The spherical electrodes 1 face each other and are separated by a discharge gap. The protrusions 2 are integrally installed at both ends of the spherical electrodes 1 facing each other, and have a protrusion length of 1/100 to 1/8 times the outer diameter of the spherical electrodes 1 and 1/100 to the outer diameter. It has an outer diameter of 1/10 times. The blower 5 generates an airflow for discharging the product generated on the protrusion 2 by the generation of the spark discharge. The blower 5 supplies air at a wind speed of 0.5 to 25 m / sec-KW at a discharge interval. Thus, the simple configuration increases the stability and durability of the high voltage pulse waveform.
