Description
Technical field
The utility model relates to a kind of electric equipment, particularly relates to a kind of high-tension fuse fingertip dismantling device.
Background technology
Usually high-tension fuse composition high voltage load switch-fuse combined electric apparatus is coordinated in high voltage load switch.When high voltage electric equipment product (containing: transformer, the motor etc.) fault that is short-circuited, high-tension fuse directly can carry out disjunction protection by insantaneous break short-circuit current, is reliable, effective protected mode.It can multiple mounting modes on high voltage load switch, can to be installed in insulation framework, to expose in atmosphere or between two insulators, fuse two ends are connected with other conductors by fuse card, mid portion is the porcelain body that quartz sand is inserted in inside, the fuse body wherein having root superfine connects as conduction, when short circuit current is by the fuse quick-break in porcelain body, the short circuiting arc of generation is absorbed by quartz sand, thus reaches the object of disengagement failure electric current.
Just can not in use after High-voltage Fuse Blow, after the high-tension fuse needing taking-up more to renew immediately, power equipment could continue to come into operation.
Existing high-tension fuse on the market comprises insulator, fusion tube, spring, card and fingertip, fusion tube is installed in insulator, the end thereof contacts fusion tube of spring, the other end contact fingertip of spring, card and fingertip are bolted the one end being installed on insulator, when fusion tube changed by needs, two people are needed to coordinate, one end that wherein a people presses high-tension fuse energetically overcomes the active force of spring, another person just can complete dismounting and be installed on bolt on card and fingertip, if fuse is arranged in insulation framework, just further increase the difficulty that fuse takes out, and waste time and energy by the way.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of high-tension fuse fingertip dismantling device, to overcome the above-mentioned defect that prior art exists.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: high-tension fuse fingertip dismantling device comprises clamping part, support bar, connecting plate and screw mandrel, clamping part arranges U-shaped shape opening, support bar is fixedly installed on clamping part, and two support bars are positioned at the both sides of U-shaped shape opening, connecting plate is bolted and is installed on support bar, connecting plate middle position arranges through hole, in the through hole of connecting plate fixed installation nut, screw mandrel is installed on nut, screw mandrel comprises the contact being installed on screw mandrel one end, be arranged at cylindrical portion and the bearing pin of the screw mandrel other end, cylindrical portion arranges pin shaft hole, bearing pin is placed through in pin shaft hole.
U-shaped shape opening part in clamping part arranges one deck rubber layer, and this rubber layer is coated on the upper surface of clamping part and the lower surface edge near U-shaped shape opening part.
Contact comprises fixed part and contact site, in fixed part, screw is set, fixed part is fixedly installed in an end of screw mandrel by the screw being installed on fixed part by screw, contact site is tubular type, the contact site of tubular type can accommodate the lug plate of fingertip, in the process of dismounting fingertip, ensure the intact of fingertip.
During use, clamping part is held between insulator two projections of high-tension fuse, pass through rotating pin, the contact of screw mandrel is made to compress the fingertip of high-tension fuse, then dismantle or assemble the bolt be installed on card and fingertip, and then bearing pin is rotated backward, make the contact of the screw mandrel fingertip leaving high-tension fuse slowly, thus complete the fusion tube changing high-tension fuse, because the U-shaped shape opening part of clamping part arranges one deck rubber layer, thus ensure can not damage insulator in the process of dismounting high-tension fuse fingertip, and pass through the use of high-tension fuse fingertip dismantling device, reduce labour intensity, reach the time that fusion tube is changed in reduction, increase work efficiency, overcome the large danger of work high above the ground difficulty large, many people operate the safe pressure brought, Reliable guarantee is provided for power equipment safety runs.
The utility model relative to existing technologies, its beneficial effect is: the high-tension fuse fingertip dismantling device that the utility model provides is light, it is flexible, simple to operate to use, reduce labour intensity, reach the time that fusion tube is changed in reduction, increase work efficiency, overcome the large danger of work high above the ground difficulty large, many people operate the safe pressure brought, and provide Reliable guarantee for power equipment safety runs.
