Abstract

The utility model discloses a high pressure fuse, comprising a base, a main body insulator, a fusion tube and a fusion core arranged in the fusion tube; left and right ends of the fusion tube are respectively provided with a left end cover assembly and a right end cover assembly, wherein the left end cover assembly is composed of a left end cover seat, a lock catch bar, a left end cover, a lock catch ring and a left binding post; the left end cover seat is fixed to the left end of the fusion tube; the upper end of the left end cover seat is in movable connection with the lock catch bar and the lower end of the left end cover seat is movably provided with a left end cover coupling with the left end cover seat; the central section of the lock catch bar is provided with the lock catch ring; the left end cover seat is provided with the left binding post. According to the technical scheme, the high pressure fuse has a simple structure, is safe and reliable and is convenient and fast to operate; the case that a fuse end cover can not be opened caused by corrosion of end cover installation screws can be avoided, labor intensity is effectively reduced, time of n replacing a fusion core is shortened and security and stability of power grid operation are raised.

Description

A kind of high-tension fuse
(1), technical field:
The utility model relates to high tension apparatus, relates in particular to a kind of high-tension fuse on 35KV.
(2), background technology:
In the actual motion of electrical network, owing to be struck by lightning, press the change failure and other reasons 35KV high-voltage wire iron-melting fusing phenomenon can often occur, at this moment, staff's power failure is in time repaired and is changed.But in practical operation, repairing more changes jobs exists following problems: the first, and the fuse of setting height(from bottom) about 3.5 meters, structurally inconvenient operations staff replacings of ascending a height, greatly dangerous; The second, adopt spring compression assembling on the device structure, the normal operation maintenance of inconvenience and more changing jobs on framework, in real work, when the staff works at change of fuse, all the molten tool of the whole series is pulled down, more finish changing or load onto complete standby molten tool on ground, incured loss through delay the time, increased cost; The 3rd, the reason of fuse failure is caused by thunderbolt more than 98%, so change the work of fuse, all is to carry out in the rainy day basically, and difficulty is bigger, has influenced operating personnel's personal safety.In addition; because equipment is in outdoor operation for a long time; each connecting screw corrosion is serious; sometimes must adopt hacksaw cutting; work difficulty is big, the replacing time is long, generally must be cooperated just by 2-3 people and can finish change of fuse work, causes the fuse failure overlong time; very big to protecting, measure influence, unfavorable power network safety operation work.
(3), summary of the invention:
The purpose of this utility model is to provide a kind of high-tension fuse, this high-tension fuse is simple in structure, safe and reliable, easy to operate, quick, can prevent being again to have reduced labour intensity effectively owing to end cap is installed the situation that fuse end cap that the screw corrosion causes can't be opened, shorten the time of changing fusible core, improved the fail safe of operation of power networks, stability.
For achieving the above object, a kind of high-tension fuse of the utility model, comprise base, be fixed on the base the main body insulator with the main body insulator by being connected the fixedly connected fusion tube of anchor ear and being located at fusible core in the fusion tube, two ends, the left and right sides at fusion tube are respectively equipped with left end cap assembly and right end cap, be provided with right binding post at right end cap, it is characterized in that: described left end cap assembly is made up of left end cage, locking-bar, left end cap, snap close ring and left binding post; The left end cage is fixed on the left end of fusion tube, upper end at the left end cage is connected with locking-bar, be movably equipped with the left end cap that is complementary with the left end cage in the lower end of left end cage, be provided with the snap close ring at the middle part of locking-bar, also be provided with left binding post on the left end cage.
In technique scheme, be provided with snap close type left end cap at the left end of high-tension fuse, snap close type end cap only need draw back locking-bar when changing fusible core, and the unload lock clasp just can the very convenient left end cap of opening, thereby changes the fusible core that has burnt out in the fusion tube.The technical solution of the utility model is simple in structure, safe and reliable, easy to operate, quick, can prevent owing to end cap is installed the situation that fuse end cap that the screw corrosion causes can't be opened, be again to have reduced labour intensity effectively, shorten the time of changing fusible core, improved the fail safe of operation of power networks, stability.
(4) description of drawings
Fig. 1 is the structural representation of a kind of high-tension fuse of the utility model;
Fig. 2 is the structural representation of left end cap assembly among Fig. 1.
(5), embodiment:
Below in conjunction with accompanying drawing a kind of high-tension fuse of the utility model is described further.
As Fig. 1, Fig. 2 as seen, present embodiment is mainly used in the outdoor bus of 35KV, circuit is pressed the current-limiting protection that becomes.The high-tension fuse of present embodiment by base 1, be fixed on main body insulator 2 on the base 1, with main body insulator 2 by be connected the fixedly connected fusion tube 4 of anchor ear 3, fusible core 5, left end cap assembly and the right end cap that is located in the fusion tube 4 formed, left end cap assembly and right end cap 6 are fixed on the two ends, the left and right sides of fusion tube 4 respectively by screw, be provided with right binding post 7 at right end cap 6, in the present embodiment, the left end cap assembly is made up of left end cage 8, locking-bar 9, left end cap 10, snap close ring 11 and left binding post 12; Left end cage 8 is fixed on the left end of fusion tube 4, be connected with locking-bar 9 in the upper end of left end cage 8, be movably equipped with the left end cap 10 that is complementary with left end cage 8 in the lower end of left end cage 8, be provided with snap close ring 11 at the middle part of locking-bar 9, also be provided with left binding post 12 on the left end cage 8.
In the present embodiment, the fuse tube end cap has substituted nut by snap close type mounting means and has fixedly mounted mode, and snap close type left end cap assembly only needs locking-bar 9 to be drawn back unload lock clasp 10 when changing fusible core, just can be easy to open left end cap 10, thereby just can change the fusible core 5 of 4 li of fusion tubes easily.Present embodiment is in actual mechanical process, simple in structure, safe and reliable, easy to operate, quick, can prevent being again to have reduced labour intensity effectively owing to end cap is installed the situation that fuse end cap that the screw corrosion causes can't be opened, shorten the time of changing fusible core, improved the fail safe of operation of power networks, stability.
