技术定义与适配语境
典型 分弧板 会按材料、尺寸公差、适配关系和失效风险在 电气设备制造 中评估。

Splitter plates are critical insulating components within arc chutes, designed to divide, cool, and extinguish electrical arcs generated during circuit interruption in medium to high-voltage electrical equipment. These plates create multiple series gaps that increase arc voltage, stretch the arc path, and facilitate rapid deionization through thermal quenching and magnetic blow-out effects, ensuring safe interruption of fault currents.

定义
Splitter plates are critical insulating components within arc chutes, designed to divide, cool, and extinguish electrical arcs generated during circuit interruption in medium to high-voltage electrical equipment. These plates create multiple series gaps that increase arc voltage, stretch the arc path, and facilitate rapid deionization through thermal quenching and magnetic blow-out effects, ensuring safe interruption of fault currents.
工作原理
Splitter plates operate by dividing a single high-energy arc into multiple smaller arcs across series gaps, increasing total arc voltage beyond the system voltage to force extinction. The plates absorb heat through thermal mass, cool arc plasma via gas generation from ablative materials, and utilize magnetic fields to drive arcs into narrow slots for elongation and fragmentation, accelerating deionization and preventing re-strike.
