Application number be 200820230882.0 utility model be a kind of outdoor high-voltage fuse wiring cap; the technical problem solved is to provide a kind of outdoor high-voltage fuse wiring cap of easy accessibility; it can make replacing, maintenance melt pipe convenient and swift; technical scheme is: offer a melt pipe entrance at cap body upper part, melt pipe entrance is provided with an end cap; This end cap is flexibly connected with a connecting bolt through connecting rod, and end cap freely can rotate around connecting bolt, and connecting bolt is by the little seat supports be located on cap body; A set of retaining mechanism of end cap is provided with on the end face of end cap and on cap body outer wall.Described retaining mechanism can be tumbler lock mechanism, comprises the locking bolt chamber be located on end cap end face, dead bolt, stage clip, locking bolt, little handle and is located at keeper corresponding with latch bolt position on cap body lateral wall.Good effect is; Structure is simple, convenient to disassembly, changes, overhauls melt pipe easily, alleviate labor strength, improve the efficiency of maintenance electrical network, circuit, can apply high-voltage and current-limitation fuse field up till now.
But the fuse in such scheme by further improving, mainly by the improvement to conventional fuse dismounting parts, can also realize a kind of new-type fuse of time saving and energy saving less manpower.
Utility model content
The purpose of this utility model is to provide a kind of fast disassembly type outdoor high-voltage current-limiting fuse, and it utilizes fast disassembly type bolt, realizes the quick-detachment of fuse and the quick-replaceable of melt pipe, time saving and energy saving.
The technical scheme adopted for realizing the purpose of this utility model is: a kind of fast disassembly type outdoor high-voltage current-limiting fuse, comprise porcelain bushing, melt pipe and insulator, described porcelain bushing is connected by clamp flange with described insulator, described insulator is bar type post insulator, described melt pipe is fixed in described porcelain bushing by wiring end cap, and described wiring end cap is fast disassembly type bolt.
Described fast disassembly type bolt comprises handle, tightening latch and dop, and the connecting portion of described handle and described tightening latch arranges end cap, arranges spring between described end cap and described dop.
Described fast disassembly type bolt surface scribbles insulating lacquer layer.
It is hinged that described handle and described tightening latch pass through screw.
Described handle is pressure-lift, in crescent shape structure.
Described handle is rotary, in I-shaped structure.
Further, described handle is for being semi-circular draw ring structure.
Because melt pipe is fixed in porcelain bushing by wiring end cap, so the quick-replaceable of melt pipe will be realized, need from the improvement of wiring cap end, wiring end cap is fast disassembly type bolt, comprise handle, tightening latch and dop, the connecting portion of handle and tightening latch arranges end cap, arranges spring between end cap and dop.When changing, first driving whole fast disassembly type bolt to rotate by handle, to make wiring end cap unload, only can unload the end cap of one end, also can unload two ends, at this moment can complete rapidly the replacing of melt pipe.After melt pipe completes replacing, fast disassembly type bolt is reinserted the ending cover hole of porcelain bushing, and inwardly extrude, be advisable to compress melt pipe, draw-in groove now in dop and porcelain bushing adapts, and can begin through rotatable handle thus drive tightening latch to rotate, reaching the object tightened.
