Further, the length of the bolt is 170~190mm.
Compared to the prior art, the utility model has the following beneficial effects:
1, the setting of the retaining ring, pallet can overcome bullet instead of manpower during high-tension fuse replaces fusion tube
The elastic compression end cap of spring, so that personnel convenient to overhaul easily twist the bolt on end cap, therefore, the utility model is conducive to reduce
Personnel amount needed for high-tension fuse replacement and saving manpower, improve working efficiency.In addition, due to pallet and end cap contact surface
Product is big, can effectively compress end cap, it is thus possible to eliminate safe hidden trouble, avoid in disassembly process spring from not compressing and make personnel by
To mechanical wounding.
2, the locking cyclization pallet preferably uses bolt attaching nut to be attached, and has connection simplicity, is connected firmly
The features such as.
3, since the retaining ring includes two hemizonid, it is convex that the both ends of two hemizonid are respectively equipped with a third
The third lug of ear, the respective end of two hemizonid is superimposed, and constitutes second lug, so that retaining ring and pallet connect
While connecing, also realize the connection cooperation of two hemizonids, thus make the structure of retaining ring more succinctly, accessory it is few, it is at low cost.
The utility model is described in further detail with reference to the accompanying drawings and embodiments；But the utility model is a kind of high
Pressure change of fuse specific purpose tool is not limited to the embodiment.
