Abstract
The utility model discloses a kind of current limiting fuse quick-tripping device, relate to power equipment manufacturing technology field; Comprise fuse tube, the wiring end cap being socketed in the porcelain bushing outside fuse tube and being abutted respectively with fuse tube two ends by spring; One of them wiring end cap both sides is respectively arranged with Removable hook; Fixing hangers is socketed in the outside of porcelain bushing one end, and Removable hook is flexibly connected with fixing hangers.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.
Description
Technical field
The utility model 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 purpose of this utility model is to provide a kind of current limiting fuse quick-tripping device, and 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 adopted in the utility model 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 utility model 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 utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
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 utility model 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.
