The utility model has the advantages of simple structure, convenient use, safety, reliability, manpower saving and high work efficiency, reducing the labor intensity of staff, at thesame time avoiding occurrence of other accidents at the dismantling of the fuse, and also ensuring the quality of the replaced fuse. The fuse is replaced in a relatively short period of time, ensuringthe safe, stable and economic running of a power grid. The special replacing tool of the outdoor 35kV PT fuse has strong practicality and promotion value.
Description
Technical field
The utility model belongs to electric equipment upkeep operation technical field, is specifically related to a kind of outdoor 35kV PT fuse special replacement tool.
Background technology
In transformer station, owing to multiple reasons such as harmonic wave or operation cause the voltage ripple of power network scope bigger, and fuse two ends rubber cushion is aging, poorly sealed rainwater intrusion etc., cause that PT fuse blows number of times is more, this recovers normal operation with regard to needing in time to change fuse assurance PT function fast in the shortest time.In order to make the current-carrying part contact of outdoor 35kV PT fuse two ends good, producer is designed to the pressure texture that two ends are spring with the internal structure of fuse sleeve pipe, thereby cause when changing elastic force big, at least need two people high-altitude cooperations could change successfully, the work high above the ground space is narrow and small, there is big potential safety hazard, when fixed roof, will offset the elastic force of two springs in two ends with manpower, the staff firmly is difficult to evenly, if firmly degree is not enough, will cause the loose contact of fuse two ends, the screw hole dislocation also appears in fuse then easier fusing often, and top cover is difficult to fix.In addition, because screw is too little, often landing from hand is fallen on the ground or in the lawn, the searching difficulty is wasted a large amount of time.
The utility model content
The utility model is in order to solve weak point of the prior art, and a kind of special replacement tool for outdoor 35 kV PT fuses of simple in structure, convenient to use, safe and reliable, high efficiency is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: special replacement tool for outdoor 35 kV PT fuses, comprise that the porcelain bushing chuck and the porcelain bushing that be arranged in parallel take over a business, porcelain bushing chuck and porcelain bushing are taken over a business correspondence position and are all offered bayonet socket, are provided with the spacing adjusting device between porcelain bushing chuck and porcelain bushing are taken over a business.
Described spacing adjusting device is formed by two screw rods of all taking over a business perpendicular to porcelain bushing chuck and porcelain bushing and with the nut that screw rod is spirally connected, the same end of two screw rods is fixedlyed connected with the porcelain bushing chuck, and porcelain bushing is taken over a business to be located on two screw rods and with its gap and is connected.
Described porcelain bushing chuck and porcelain bushing take over a business to be " U " shape platy structure, the bayonet socket shape on porcelain bushing chuck and porcelain bushing are taken over a business all with its appearance similar, wherein the porcelain bushing bayonet socket size of taking over a business is less than the bayonet socket size of porcelain bushing chuck.
Described two screw rods are symmetrical arranged about the bayonet socket center line of porcelain bushing chuck.
Described porcelain bushing chuck bayonet socket edge is provided with one deck liner.
Described nut is a butterfly nut.
Adopt said structure, the porcelain bushing chuck is blocked the existing draw-in groove of fuse porcelain bushing, porcelain bushing withstands fuse porcelain bushing end face, operation room is regulated (reducing) porcelain bushing chuck and the porcelain bushing distance between taking over a business apart from adjusting device then, overcome the elastic force of the spring in the fuse porcelain bushing, thereby reach the purpose of light dismounting fuse porcelain bushing top cover; The spacing adjusting device adopts the rotation nut to shorten screw rod gradually and then compresses the top cover of fuse porcelain bushing, and is this simple in structure, easy and simple to handle; Porcelain bushing chuck and porcelain bushing are taken over a business profile and are " U " shape platy structure, be convenient to clamp and cooperate and saving material and cost, existing draw-in groove is suitable on the bayonet socket size of porcelain bushing chuck and the fuse porcelain bushing, and the bayonet socket size that porcelain bushing is taken over a business and the top cover of fuse porcelain bushing are suitable; Being symmetrical arranged of two screw rods makes that top cover is stressed evenly when the precession nut, is convenient to dismounting and protects fuse injury-free; Liner can avoid the porcelain bushing chuck to fuse porcelain bushing surface tear; When adopting butterfly nut to make precession, nut is convenient to operation, more laborsaving; The utility model is simple in structure, esy to use, safe and reliable, save manpower, high efficiency, reduced staff's labour intensity, other fortuitous events have been avoided when the dismounting fuse, taking place simultaneously, the quality of the fuse after also having guaranteed to change, change fuse within a short period of time, guarantee high-voltage fence safety, stable, operation economically, had stronger practicality and promotional value.
