This article describes the design principle of the device and its parts, analyses the safe current-carrying capacity, voltage drop, sliding contact and are extinction performances of the device.
文章介绍了装置的设计思想和部件设计原理，对产品的安全载流、电压损失、滑接性能、灭弧性能进行了分析。
But at higher temperature, PD extinction voltage is seen clearly.
但在高温下，能看到明显的熄灭电压。
The reduction of the residual current of the ground-fault point is beneficial to the extinction of the grounding arc and to the reduction of the intermittent arc grounding over voltage.
减小接地故障点的残流有利于接地电弧的瞬间熄灭及降低间歇性电弧接地过电压。
