In addition,, in this programme, the ampacity of the interlude that is arranged so that each interior fuse of coiling is less than the ampacity at two ends.Wherein, respectively the interlude of this interior fuse is arranged with a silicon rubber insulation pipe, Inner fuse is independently isolated by silicon rubber insulation pipe, concentrates and is assemblied on fuse board, and every interior fuse has oneself independently motion space, be equivalent to independently arc control device, the impurity producing while making the action of interior fuse etc. is completely sealed in silicon rubber insulation pipe inside, can not affect adjacent capacity cell, also can long-living strong shock wave, avoid the expansion of fault, improved the useful life of capacitor.In addition, Inner fuse assembly has been given full play to the fuse protected effect that should have of Inner, has avoided consequent potential safety hazard.
Preferably, the internal diameter of described metal connecting tube is 7.62~10.16 millimeters.
Preferably, the external diameter of described metal connecting tube is 10.41~13.21 millimeters.
Preferably, the length of described metal connecting tube is 13.46~16.51 millimeters.
In the utility model, above-mentioned optimum condition can combination in any on the basis that meets this area general knowledge, obtains each preferred embodiment of the present utility model.
Positive progressive effect of the present utility model is: (1) utilizes the mechanical cold weld of non-bond pattern, the damage that medium and the insulation etc. of assurance capacitor internal can not be subject to being brought by hot working, and condenser loss is little, extends the useful life of capacitor.(2) connect more fully the electric power that can better deal with short circuit current, shove etc. brought.(3) simple to operate and safety makes technique more stable, more guaranteed to product quality, safer to operating personnel.
