摘要
介绍了BSB7系列家用及类似场所用过电流保护断路器的产品结构和工作原理、基本参数和主要技术特点,并比较了液压-电磁脱扣器与热-磁式脱扣器的特点。提出BSB7系列断路器既保持了液压-电磁式脱扣器的过载保护特性稳定、使用环境温度范围广、节能环保等的优点,又提高了短路分断能力,满足在-40^+85℃温度环境下终端配电系统的需要。
This paper introduced the product structure,operating principle,fundamental parameters,and main technical characteristics of BSB7 series circuit breakers for overcurrent protection for household and similar installation.The characteristics were compared between hydraulic-electromagnetic release and hot-magnet release. BSB7 series circuit breakers not only has the advantages of stable overload protection characteristics,wide ambient temperature range,energy conservation and environmental protection,but also improves the short-circuit breaking capacity,which meets the requirements of terminal power distribution system at- 40 ~ ＋ 85 ℃ of temperature environment.
