德运电气有限公司生产销售的HRW以及RW系列33kV~35kV跌落式熔断器在正常运行时,熔丝管借助熔丝张紧后形成闭合位置。当系统发生故障时,故障电流时熔丝迅速熔断,并形成电弧,消弧管受电弧灼热,分解出大量的气体,使馆内形成很高压力,并沿管道形成纵吹,电弧被迅速拉长而熄灭。熔丝熔断后,下部动触头失去张力二下翻,锁紧机械,释放熔丝管,熔丝管跌落,形成明显的开断位置。当需要拉负荷时,用绝缘杆拉开动触头,此时主动、静动触头仍然接触,继续用绝缘杆拉动触头,辅助触头也分离,在辅助触头之间产生电弧,电弧在灭罩狭缝中被拉长,同时灭弧罩产生气体,在电流过零时,将电弧熄灭。
33kV~35kV系列跌落式熔断器是输配电系统中户外高压保护电器,装置在配电变压器高压侧或配电线支干线路上,用作变压器和线路的短路、过载保护及分、合负荷电流。产品特点:1、跌落式熔断器中装上高压熔丝后,用于保护电路和切断故障电流;2、采用复合(硅橡胶)材料绝缘子绝缘,绝缘性能好;3、熔丝熔断后,熔管自动跌落,形成明显隔离距离,十分安全。
复合跌落式熔断器由复合(硅橡胶)绝缘支架和熔丝管二部分组成,静触头安装在绝缘支架两端,动触头安装在熔丝管两端,熔丝管由内层的消弧管和外层的酚醛纸管或环氧玻璃布管组成。拉负荷跌落式熔断器增强弹性辅助触头及灭弧罩,用以分、合负荷电流。
