Description
Technical field
The invention belongs to electric equipment upkeep operation technical field, be 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 just needs in time to change fast fuse and guarantees to recover normal operation with the PT function 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, and need two people high-altitude cooperations could change successfully at least, 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.
Summary of the invention
The present invention is in order to solve weak point of the prior art, and a kind of outdoor 35kV PT fuse special replacement tool of simple in structure, convenient to use, safe and reliable, high efficiency is provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: outdoor 35kV PT fuse special replacement tool, it comprises 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, offer the strip through hole between bayonet socket that porcelain bushing is taken over a business and the outward flange, the porcelain bushing chuck is made up of the snap ring of two semi-annular shapes, two snap rings, one end is hinged, the other end removably connects by latch, is 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 the annular platy structure, bayonet socket on porcelain bushing chuck and porcelain bushing are taken over a business is circular configuration, the bayonet socket of porcelain bushing chuck is connected to form by two snap rings, and the bayonet socket size dimension that porcelain bushing is taken over a business is less than the bayonet socket size dimension of porcelain bushing chuck.
Described two screw rods are separately positioned on two snap rings and about the bayonet socket center symmetry of porcelain bushing chuck.
The bayonet socket surface of described porcelain bushing chuck is provided with one deck liner.
Described nut is a butterfly nut.
Adopt said structure, the bayonet socket that two snap rings of porcelain bushing chuck are formed blocks the existing draw-in groove of fuse porcelain bushing, strip through hole on porcelain bushing is taken over a business is the aluminium row who is used for passing the top cover end, 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 take over a business to be the annular platy structure, bayonet socket on it is circular configuration, existing draw-in groove is suitable on the bayonet socket size dimension of porcelain bushing chuck and the fuse porcelain bushing, and the top cover of bayonet socket size dimension that porcelain bushing is taken over a business and fuse porcelain bushing end is suitable; Being symmetrical arranged of two screw rods makes top cover stressed evenly, is convenient to dismounting; Liner can avoid the porcelain bushing chuck with fuse porcelain bushing surface tear; When adopting butterfly nut to make precession, nut is convenient to operation, more laborsaving; The present invention 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.
