As improvement, be set with the observation piece corresponding on the fuse with secondary cartridge fuse position.
In order to strengthen the reliability of judging whether this fuse fuses, the observation piece that on fuse, has been locked, it is corresponding with secondary cartridge fuse position to observe piece.Be locked in the fuse outside because observe piece, more much bigger than fuse volume, so its observing effect is more obvious, convenient during judgement.
As further improvement, be provided with the protection tube of suit fuse in the inner chamber of secondary cartridge fuse, the cartridge fuse lower end is provided with the protection tube upper end and clamps the portion that clamps that cooperates.
Can produce electric arc during fuse failure; For extinguish arcs as early as possible; The air of cartridge fuse implosive can spray along the cartridge fuse inner chamber from top to bottom, has so just realized the arc extinguishing effect, and the hot gas that is mingled with electric arc is through secondary cartridge fuse the time; Can on secondary cartridge fuse inwall, stay stain more or less, observe the next time that influences fuse.In secondary cartridge fuse behind the plug-in mounting protection tube, during fuse failure, stain will be attached on the protection tube inwall, thereby plays the effect of the secondary cartridge fuse of protection.Change protection tube for ease, the cartridge fuse lower end is provided with protection tube and clamps the portion that clamps that cooperates.
As a kind of implementation, the said portion of clamping is Ka Tai or groove.
As further improving, Ka Tai is provided with the decompression line corresponding with the protection tube inwall again.
The air blast that produces during fuse failure is very powerful; Might be in the time of can not in time discharging cartridge fuse at short notice along the protection tube upper end around outside protection tube, like this, the stain that is mixed in the air-flow will influence secondary cartridge fuse inwall; After on the Ka Tai decompression line corresponding with the protection tube inwall being set; The decompression line can cushion air blast, stops air-flow to flow laterally, helps to protect secondary cartridge fuse.
As further improving, be provided with the gap between secondary cartridge fuse and the protection tube.
Between secondary cartridge fuse lateral wall and protection tube madial wall, the gap is set, when changing protection tube, can reduces the friction between protection tube outer wall and the secondary cartridge fuse inwall, make replacing more fast, conveniently.
In sum, adopt the fuse of this structure, simple in structure, can judge fast whether fuse fuses, especially be suitable as fuse switch and use, can make the attendant under the situation of not climbing, judge whether to need to change fuse fast.
