(3it P=- ■ C: Proportional constant 1: Short final current t: Short circuit duration V: Tank internal volume When a certain pressure is reached, the pressure relief plate (7) ruptures, and the internal volume increases by adding an adjacent tank. Therefore, the internal pressure will decrease.For example, if the adjacent volume is the same, it will be ↓.If the arc continues and the pressure exceeds a certain value, the next spacer will release pressure, and the internal pressure will rise below a certain value. Since the spacer is configured as shown in FIG. 2, no cracks occur in the spacer and no arc gas is released to the outside.
