摘要
过电流保护断路器瞬时脱扣性能应符合GB10963《家用及类似场所用过电流保护断路器》、GB14048.2《低压开关设备和控制设备低压断路器》等标准中的瞬时脱扣性能要求,目前通用的过电流保护断路器瞬态脱扣特性检测方法主要采用光敏纸记录器、瞬态峰值记录仪(或峰值表)、数据采集控制系统等,这些方法各有其优缺点,文章详细介绍了一种通用性强,设备操作简单、直观,试验可信度高,具有较高推广价值的检测技术新方法,该系统在实验室运行近一年,运行状况良好。
The instantaneous tripping of the over-current protection circuit breakers should comply with the standard GB10963《Circuit-breakers for over-current protection for household and similar installation》and the standard GB14048.2《Low-voltage switchgear and control-gear-Low-voltage circuit breakers》. The common test systems for instantaneous tripping usually employs photosensitive recorder, instantaneous peak value meter or data collecting and controlling apparatus. But these methods all have disadvantages besides some strongpoints. Thus another test system is introduced in this paper, which can be generally used and has the advantages of easy operation and authentic report. The system has been applied in the laboratory for a year and has presented a good performance.
