RXWO-35、RW10-35户外高压限流熔断器

□熔断器由熔体管、瓷套、紧固法兰、棒形支柱绝缘子和接线端帽等组成。用压装的方法将两端的接线端帽和熔管固定在瓷套内、 然后用坚固法兰把瓷套固定在棒形支柱绝缘子上，其结构说明和外形尺寸如图所示。
□熔体管采用含氧化硅较高的原料作灭弧介质，应用小直径的金属线做熔丝。当过载电流或短路电流通过熔管时，熔丝立即熔断， 电弧发生在几条并联的窄缝中，电弧中的金属蒸汽渗入石英砂中，迅速把电弧熄灭。所以，这种熔断器·性能良好，开断容量大。
□the fuse is made up of fuse pipe,porcelain sheath，fastening flange，support insulator，terminal cap etc．separately fix up the terminal cap and fuse pipe in the porcelain sheath by the p ress way，then use the fastening flange to fix up the porcelain sheath on the support insulator.refer to the chart for its structure and external dimension. the fuse pipe adopts the material wlth high content of oxide siiicon as the arc extinguishing media,and uses small-diameter metal iine as fuse wi re．when the overload current or the short-circuit current passes the fuse pipe,the fuse wire immediately is broken,the electric arc occurs in a few paraliel-connection gaps,the metal steam in the electric arc inflltrates into the quartz sand,and it is iiberated strongly,then puts out the electric arc. thus，this fuse has good performance and big b reaking capacity.

□rnl型充石英砂户内高压熔断器用于电力线路的过载及短路保护，有较大的开断能力，故亦可用于保护电力系统输出的支路，城 市的供电线路、工矿企业、农业变电站的馈电线路。
□rnl型熔断器是由支柱绝缘子、触座、熔丝管和底板等四部分组成，支柱绝缘子安装在底板上，触座固定在支柱绝缘子，熔丝管 放在触座中固定，熔丝管管内熔丝缠在有棱的芯子上，然后充填石英砂，两端铜帽用端盖压紧，用锡焊牢，以保护密封。
□当通过过载电流或短路电流时，熔丝立即熔断，同时产生电弧，石英砂就立即把电弧熄灭。在熔丝熔断时，弹簧的拉线也同时熔 断，并从弹管内弹出，这就指示熔断器完成了任务。
□rn1 filled indoor high-voltage fuse is applied to protect tile overload and short circuit of powe rline,and has very blg breaking capacity, so it is also applied to protecting the branch of power system，power line of city,feed circuit of industry enterprise and agricuitural substation．
□rn1 fuse is made up of support in sulators，contact base，fuse iink and base board the suppoort insulator is installed on the base-board，the contact base is fixed on the support insulator，the fuse pipe is fixed in the contact base,the fuse wire in the fuse pipe is riiled on the cord with arris，then fill tile quartz sand,use tile te rminal cover to pasess the copper cap,and seal the pipe by welding the tin．
□when the overload current or short-circuit current passes,the fuse wire immediately is broken,at tile same time the electric arc occurs，and tile quartz sand immedlately puts out the electric arc. when tile fuse wire is broken，tile connection line of spring is also broken,and tile spring comes out from the pipe,this means the fuse already finishes its work．

□高压熔断器适用于输电线路与电力变压器短路及过载保护，是保护电力设备不受损害的Zui简单的一种电器。
□高压熔断器适用于海拔1000米下，环境温度不高于+40℃，不低于-40℃使用，不适用于有燃烧、爆炸危险、剧烈振动、摆动冲 击的场所及重污区。
□high-voltage fuse is applied to protect the short circuit and overload of electricity transmission line and transformer，and is the simplest electrical appliance to prevent the power e from being broken．the high-voltage fuse is applicable to the conditions with the altitude blow 1000meters and the temperature in the range of+40℃ and-40℃，but it is not applicable to the location with in flammation and explosion danger．strong vib ration．swing impact and serious pollution．
