设有关机残留电压自动释放回路，确保维护安全；
With residual voltage automatic release circuit to guarantee the safety.
结果表明，随着直流电压幅值的增加或直流电压施加时间的延长，残留电荷量均逐渐增大并趋于饱和；
The accumulated results show that as the amplitude and the application time of DC voltage increase, the amount of residual charge increases and approaches a saturated value;
