标准范围

IEC 60947-9-2:20 21涵盖内部电弧故障控制装置，以下简称IACD，旨在:-通过(至少)处理内部电弧故障的光学效应来检测低压开关设备和控制设备组件中的内部电弧故障，以及-操作缓解装置（外部或组合）以最小化内部电弧故障的影响。

IEC 60947-9-2:2021 covers internal arc-fault control devices, hereinafter referred to as IACD, which are intended to:
– detect internal arc-faults in low-voltage switchgear and controlgear assemblies, by processing (at a minimum) the optical effect of an internal arc-fault, and
– operate mitigation device (either external or combined) in order to minimize the effects of the internal arc-fault.
