    摘要: A semiconducting fluid stream controls arcing between the contacts of a high-voltage circuit interrupter. The fluid stream initially establishes a low-resistance conducting path between the interrupter contacts as they separate when the interrupter is activated. As the spacing between the contacts increases the resistance of the fluid stream also increases. The increased resistance reduces the load current to a low level at which circuit interruption is accomplished without significant arcing. The semiconducting fluid also extinguishes any arc which forms as the interrupter contacts separate.
