目前常用的电气火灾监控系统及其探测监控器,对于电气短路故障缺乏有效的限流保护手段。传统设备的控制速度较慢,一旦发生短路故障,瞬时剧增的短路电流无法得到抑制,以至于短路点处产生高热及危险火花引发火灾。上海诚佳电子科技有限公司研究开发的基于微秒级快速限流技术的电气防火限流式保护器,有效解决了传统监控设备的缺陷。其分断速度更快,使用寿命更长,能在短路故障发生时,以<150μs的速度有效抑制短路电流的剧增,从而避免短路点产生危险火花,减少电气火灾危害,维护社会用电安全。
At present, the commonly used electrical fire monitoring system and its detection monitor do not have effective current-limiting protection means for electrical short-circuit faults. The control of traditional equipment is slow. In the event of a short-circuit fault, the instantaneous surge of short-circuit current can not be suppressed, resulting in high heat and dangerous sparking at the short-circuit point. Shanghai Cheng Jia Electronic Technology Co., Ltd. research and development based on microsecond fast current limiting technology of electrical fire current limit protectors, effectively solve the shortcomings of the traditional monitoring equipment. Its breaking speed is faster and its service life is longer. It can effectively suppress the sharp increase of short circuit current at the speed of <150μs in the event of a short circuit fault, thereby avoiding dangerous sparks at short circuit points, reducing electrical fire hazards and maintaining social electricity safety.
