灭弧栅片

电弧分弧板，又称去离子板，是断路器、接触器和开关等电气分断装置中的关键部件。它们由多块平行的金属板组成，板间以绝缘材料隔开，并安装在灭弧室内。当电路分断产生电弧时，这些板将电弧分割成多个小段，提高其电压需求，并通过热传导和去离子作用快速冷却电弧，从而熄灭电弧，防止设备损坏。

电弧分弧板的工作原理基于电弧分割和冷却。当触头间产生电弧时，电弧被强制进入板组。板将单一电弧分割成串联的多个短弧，每个短弧都需要额外的电压来维持。同时，金属板通过热传导吸收电弧热量，而绝缘间隙通过冷却和离子复合促进等离子体的去离子，迅速增加电弧电阻，直至电流无法维持，电弧熄灭。

Arc splitter plates operate on the principle of arc division and cooling. When an electrical arc is drawn between contacts, it is forced into the plate assembly. The plates divide the single arc into multiple shorter arcs in series, each requiring additional voltage to sustain. Simultaneously, the metal plates absorb heat from the arc through thermal conduction, while the insulating gaps promote deionization of the plasma by cooling and recombination of ions, rapidly increasing arc resistance until current cannot be maintained and the arc is extinguished.
