WTBK-0.5型低压刀熔开关
Detailed product description:
概述
WTBK-0.5型低压刀熔开关适用于户外500伏50赫兹的配电线路,作为变压器低压侧的保护与过载保护,在一定的条件下可以切合空载变压器、空载线路及额定工作电流.
使用环境
海拔高度不超过2000米.
环境温度不高于+40℃,不低于-25℃.
相对湿度不大于85%(相对于+25±5℃)
无燃烧和爆炸危险.无剧烈振动和冲击,无严重腐蚀金属和绝 缘材料的化学物质的场所.
结构特点
产品主要由触刀、触头、支柱瓷瓶、底座等件组成,每3只为一组,产品体积小、重量轻,便于高空安装,触刀和触头接触采用弹簧锁紧方式,接触良好可靠,在一般振动下不会自行分闸.如维修或更换熔片,只要用钩棒拉开分闸部分将触刀摘下,在地面更换熔片再用钩棒将触刀挂上、合闸.
