跌落式熔断器

跌落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。跌落式熔断器由绝缘支架和熔丝管二部份组成,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环氧玻璃管组成。拉负荷跌落式熔断器增加弹·陛辅助触头及灭弧罩,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形成闭合位置。当系统发生故障时,故障电流使熔丝迅速熔断,并形成电弧,消弧管受电弧灼热,分解出大量的气体,使管内形成很高压力,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而下翻,锁紧机构释放熔丝管,熔丝管跌落,形成明显的开断位置。当需要要拉负荷时,用绝缘杆拉开动触头,此时主动、静助触头仍然接触,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,电弧在灭弧罩狭缝中被拉长,同时灭弧罩产生气体,在电流过零时,将电弧熄灭。

Drop-out fuse cutout and load switching fuse cutout are of outdoor used high voltage protective device. To be connecte with incoming feeder of distribution transformer or distribution lines it mainly protect dansformer or lines from shod circuit and overload. and on/off loading current. Drop. out fuse cutout is composed of insulat lnsulator suppods and fuse tube.static contacts is fixed on two sides of insulator support and moving contact jS installed on two ends of fuse tube. Fuse tube iS composed of inside arc-extinguishing tube, outer phenolic compound paper tube or epox glasstube. Load switching fuse cutout provides enforedelastic auxiliary con.tacts and arcextinguishing exclosure for switching on/off loading current.Al normally working via fuselink tightened lhe fuse tube iS fixed to form up of close position. 1n case system occure faults, fault currenl result in fuse melt immediately and take place electric arc. which let arc. extin.
guishing tube being heated and explode a lot of gas. This will produce high pressure and blow off the arc along with tube. After fuselink melt moving contact has no tightened shrength again, mechanism is loched and fuse tube drop out. Cutout now is in open position. When it needs to switchn off during cutout loadin9, operator shall via insulating operating bar pull the moving contact, at its beginning main contact and auxiliary static contact is contacted still. Whiling pulling the auxiliary contact is sepa-rated between auxiliary contacts there occur electric arc and the arc will be lengthene in arcextinguishing enclosure gap and meanwhile arc-ex-tinguishing explode gas to blow off the arc during current passing zero.
