摘　　要：分析了目前3种主流高压开关柜弧光保护方案的缺陷,提出了一种可同时检测弧光、谐波电流、温度信号的新型的高压开关柜弧光检测与保护方案。以微处理器STM32F103为控制核心,采用光纤电弧传感技术检测开关柜内部电弧信号,采用霍尔电流传感器检测过流信号,利用温控检测单元实时监测开关柜内部温度,实现了对高压开关柜中母线等电力设备的快速保护。实验表明:系统从电弧光产生到断电保护的时间在4 ms以内,极大降低了断电保护时间。The shortcomings of the current three main high voltage switchgear arc protection scheme were analyzed, and we proposed a simultaneous detection of arc, harmonic current, temperature sig- nals new high voltage switchgear arc detection and protection programs. Taking STM32F103 micropro- cessor as the control core, and using fiber optic sensing technology to detect the arc switchgear inter- nal arc signals, and using the Hall current sensors to detect an overcurrent signal, and using the real- time monitoring of temperature detection unit switchgear internal temperature, high voltage switchgear in bus rapid protection and other electrical equipment were realized. Experiments show that the system generates light from the arc to the power-off protection time is in less than 4 ms and the program great- ly reduces the power protection time.
