Abstract
The utility model discloses a kind of fuse switch fuse equipment containing insulating barrier, comprise splicing ear, lower splicing ear, sleeve pipe and be arranged on the fuse be connected with upper splicing ear, lower splicing ear in sleeve pipe, the diameter of described fuse is different, arranges in thickness interval; The described minimum place of fuse diameter arranges insulating barrier; Described insulating barrier is integral type, is connected by insulating barrier axle.The utility model has the advantages that: owing to adopting insulating barrier, and dividing plate is arranged on the minimum place of fuse diameter, and like this, once electric current causes fuse failure, fusing place separates by dividing plate, adds creep distance, can not produce electric arc; In addition, because insulating barrier is linked into an integrated entity by baffle shaft, larger pulling force can be born, can not have an impact to fuse performance.
Description
Technical field
The utility model relates to field of electrical equipment, is a kind of fuse switch fuse equipment specifically.
Background technology
Existing fuse switch fuse equipment adopts a fuse to be arranged in arc-extinguishing tube, and its drawback is the disjunction requirement that fusible core can not meet Large Copacity short circuit current, very easily causes fuse to explode, for solving this technical problem, Chinese Patent Application No. 200620147923.0 discloses a kind of high-pressure drop-out fuse fuse core of high breaking, include the fuse lead-in wire at alloy fuse and two ends thereof, alloy fuse is loaded in insulating sleeve by sealing shroud, in insulating sleeve, quartz sand is filled with around alloy fuse, the shortcoming of this patent is: because fuse bears pulling force, fuse is the disjunction guard block of overload or the fusing of short circuit overcurrent, still the load parts of pulling force are born, so just be difficult to ensure that fuse has reliable ampere-time characteristic, affect the technical performance of outdoor ac high voltage drop fuse, main cause is wherein: 1, fuse and upper, lower wire is welded to connect, welding makes fuse inevitably occur suitable burning, and change, even lose the ampere-time characteristic of fuse, 2, fuse load-bearing, operating current can make fuse stretcher strain because heat is wriggled, and causes the actual performance of whole fuse equipment and design performance to produce large deviation, have impact on it greatly and cut-off protective value.In addition, cut-off electric arc for extinguishing, the technological means that this patent adopts is filled with quartz sand in insulated enclosure sleeve pipe, and its arc blowout effect is also imperfect.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide one can bear pulling force, the fuse switch fuse equipment that arc quenching effect is good, and concrete technical scheme is as follows:
Containing a fuse switch fuse equipment for insulating barrier, comprise splicing ear, lower splicing ear, sleeve pipe and be arranged on the fuse be connected with upper splicing ear, lower splicing ear in sleeve pipe, the diameter of described fuse is different, arranges in thickness interval; The described minimum place of fuse diameter arranges insulating barrier; Described insulating barrier is integral type, is connected by insulating barrier axle.
The utility model has the advantages that: owing to adopting insulating barrier, and dividing plate is arranged on the minimum place of fuse diameter, and like this, once electric current causes fuse failure, fusing place separates by dividing plate, adds creep distance, can not produce electric arc; In addition, because insulating barrier is linked into an integrated entity by baffle shaft, larger pulling force can be born, can not have an impact to fuse performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is dividing plate place fuse-wires structure schematic diagram.
Embodiment
The utility model is illustrated below in conjunction with accompanying drawing, as shown in Figure 1 and Figure 2, the utility model comprises splicing ear 1, lower splicing ear 5, sleeve pipe 3 and is arranged on the fuse 2 be connected with upper splicing ear, lower splicing ear in sleeve pipe 3, and the diameter of described fuse 2 is different, arranges in thickness interval; The described minimum place 7 of fuse 2 diameter arranges insulating barrier 4; Described insulating barrier 4 is integral type, is connected by insulating barrier axle 6.
