Abstract
The invention discloses a fast release device of a current limiting fuse and relates to the technical field of power equipment manufacturing. The fast release device comprises a fusing pipe, a porcelain bushing connected to the outer side of the fusing pipe in a sleeving mode and terminal caps connected to the two ends of the fusing pipe respectively in an abutting mode. Movable hooks are arranged on the two sides of one terminal cap respectively, a fixed hanging lug is connected to the outer side of one end of the porcelain bushing in a sleeving mode, and each movable hook is movably connected with the corresponding fixed hanging lug. The fast release device of the current limiting fuse can solve the problems that when a fusing pipe of an existing current limiting fuse needs to be replaced, replacing is difficult, the workload is large, and replacing can be completely only through the cooperation of two persons.
Description
Technical field
The present invention relates to power equipment manufacturing technology field, especially a kind of quick-tripping device for outdoor high-voltage current-limiting fuse.
Background technology
Outdoor high-voltage current-limiting fuse is 35 kilovolts of buses, the overload of line voltage distribution instrument transformer and power transformer or other power equipment and the simplest a kind of proterctive equipment of short circuit; Existing outdoor high-voltage current-limiting fuse by fuse tube, porcelain bushing, spring, wiring end cap, the moon type flange, clamp flange and solid core post insulator etc. form, as shown in Figure 1.The method paperback that general employing press-fits is joined, and is fixed in porcelain bushing by fuse tube with wiring end cap, then is fixed on solid core post insulator with clamp flange by porcelain bushing, and a set of like this outdoor high-voltage current-limiting fuse is just assembled complete.It can level or at right angle setting, and general setting height(from bottom) is between 2500 ~ 4000 millimeters.There is following problem in existing outdoor high-voltage current-limiting fuse:
1, fuse tube difficulty is changed, particularly the fixed screw of wiring end cap runs under long-term wind, Exposure to Sunlight, the adverse circumstances that drench with rain, very easily oxidation corrosion, gives dismounting wiring end cap and changes fuse tube work and bring great difficulty (change a phase fuse tube under normal circumstances and approximately need about 60 minutes consuming time);
2, workload is large, outdoor high-voltage current-limiting fuse is generally arranged on the framework of 2500 millimeters and above height, when fuse tube changed by needs, operating maintenance personnel carry out long dismantlement work on independently framework, security risk is large, so the wiring of the wiring end cap at fuse two ends must be removed, removes the standing screw of clamp flange, whole porcelain bushing is unloaded from pillar, carries out the work of dismantling wiring end cap and changing fuse tube on the ground;
3, due to dismounting, wiring end cap is installed must adopts and press-fit method, so, whole dismounting, install to be coordinated by two people and just can complete.
Summary of the invention
The object of this invention is to provide a kind of current limiting fuse quick-tripping device, it can solve when existing current limiting fuse need change fuse tube and change difficulty, and workload is large, needs two people to coordinate the problem that just can complete.
In order to solve the problem, the technical solution used in the present invention is: this current limiting fuse quick-tripping device, comprises fuse tube, the wiring end cap being socketed in the porcelain bushing outside described fuse tube and being abutted respectively with described fuse tube two ends by spring; Described in one of them, wiring end cap arranged outside has Removable hook, is provided with fixing hangers outside the one end of the described porcelain bushing be socketed with the described wiring end cap being provided with described Removable hook, and described Removable hook is flexibly connected with described fixing hangers.
Owing to have employed technique scheme, the present invention compared with prior art, the beneficial effect had is: owing to being provided with fixing hangers and Removable hook, so when needing to change fuse tube, no matter current limiting fuse is arranged on how high framework, whole porcelain bushing need not be dismantled, in 3 ~ 5 minutes, a people just can complete the work changing fuse tube like a cork, both the labour intensity of operating maintenance personnel had been alleviated, again reduce security risk, shorten the delay time at stop of faulty equipment simultaneously, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Current limiting fuse quick-tripping device shown in Fig. 2, comprises fuse tube 1, the wiring end cap 3 being socketed in the porcelain bushing 2 outside fuse tube 1 and being abutted respectively with fuse tube 1 two ends by spring 6; One of them wiring end cap 3 arranged outside has Removable hook 4, and be provided with fixing hangers 5 outside the one end of the porcelain bushing 2 be socketed with the wiring end cap 3 being provided with Removable hook 4, Removable hook 4 is flexibly connected with fixing hangers 5.
When fuse tube 1 changed by needs, Removable hook 4 is outwards opened by two hands, Removable hook 4 is separated with fixing hangers 5, and now, fuse tube 1 outwards ejects under the promotion of spring 6, unload wiring end cap 3, take out the fuse tube 1 burnt out, replace with new fuse tube 1, aim at fuse tube 1 with the centre inside wiring end cap 3 and press gently, be suspended to by Removable hook 4 on fixing hangers 5, the inner side by past for Removable hook 4 recovery and to wiring end cap 3 of two hand equilibriums presses fastening.
Structure of the present invention is simple, practical, with low cost, and the cost of each phase is all below 100 yuan; Easy to operate, quick safety again.No matter fuse is arranged on how high framework, need not dismantle whole porcelain bushing 2, and within 3 ~ 5 minutes, a people just can change the work of fuse tube 1 by complete independently like a cork.
Claims (1)
1. a current limiting fuse quick-tripping device, comprises fuse tube (1), the porcelain bushing (2) being socketed in described fuse tube (1) outside and the wiring end cap (3) abutted respectively with described fuse tube (1) two ends by spring (6); It is characterized in that: wiring end cap described in one of them (3) arranged outside has Removable hook (4), be provided with fixing hangers (5) outside the one end of the described porcelain bushing (2) be socketed with the described wiring end cap (3) being provided with described Removable hook (4), described Removable hook (4) is flexibly connected with described fixing hangers (5).
