万联电器专业生产高压熔丝 13806607695陈工 0577-62969066 一、概述 跌落熔断器 RW12-15-200A式熔断器及拉负荷跌落式熔断器是户外高压保护电器。它装 置在配电变压器高压熔丝高压侧或配电线支干线 高压保险管 路上、用作变压器和线路的短 路、过载保护及分、 合负荷电流。跌落式熔断器由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, 动触头安装在熔丝高压熔丝管两端, 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。拉负高压保险管荷跌落式熔熔断器高压熔丝 RW12-15-200A断 器增强弹性辅助触头及灭弧罩,用以分,合负荷电流。 跌落式熔断器在正常运行时,熔丝管借助熔丝张紧后熔断器 RW12-15-200A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,并沿管熔
开关和保险丝 An electric switch is often on a wall near the door of a room. Two wires lead to the lamp in the room. The switch is fixed in one of them. The switch can cause a break in this wire, and then the light goes. The switch can also join the two parts of the wire again, then we get a light. Switch can control many different things. Small switches control lamps and radio sets because th
