Description
Technical field
The present invention relates to a kind of electric equipment, relate in particular to a kind of high-tension fuse fingertip dismantling device.
Background technology
In high voltage load switch, conventionally coordinate high-tension fuse composition high voltage load switch-fuse combined electric apparatus.When high voltage electric equipment product (containing: transformer, motor etc.) is short-circuited fault, high-tension fuse directly insantaneous break short-circuit current carries out disjunction protection, is reliable, effective protected mode.It can multiple mounting modes on high voltage load switch, can be installed in insulation framework, be exposed in air 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, wherein there is the superfine fuse body of root to connect 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, thereby reaches the object of disengagement failure electric current.
After High-voltage Fuse Blow, just can not use, after needs take out the high-tension fuse more renewing 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, one end in contact fusion tube of spring, the other end contact fingertip of spring, card and fingertip are bolted the one end that is installed on insulator, when needs are changed fusion tube, need two people 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 the bolt on card and fingertip, if fuse is arranged in insulation framework, just more increased the difficulty that fuse takes out, and waste time and energy by the way.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of high-tension fuse fingertip dismantling device, the above-mentioned defect existing to overcome prior art.
For solving the problems of the technologies described above, the technical solution used in the present invention 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, place, connecting plate centre 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 that is installed on screw mandrel one end, be arranged at columnar portion and the bearing pin of the screw mandrel other end, columnar 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, the screw that is installed on fixed part by screw is fixedly installed in fixed part one end of screw mandrel, contact site is tubular type, the contact site of tubular type can be accommodated the lug plate of fingertip, in the process of dismounting fingertip, guarantees the intact of fingertip.
During use, clamping part is held between two projections of insulator of high-tension fuse, pass through rotating pin, make the contact of screw mandrel compress the fingertip of high-tension fuse, then dismounting or assembling are installed on the bolt on card and fingertip, and then rotate backward bearing pin, the contact that the makes screw mandrel fingertip that leaves high-tension fuse slowly, thereby complete the fusion tube of changing high-tension fuse, because the U-shaped shape opening part of clamping part arranges one deck rubber layer, thereby guarantee can not damage insulator in the process of dismounting high-tension fuse fingertip, and by the use of high-tension fuse fingertip dismantling device, reduced labour intensity, reached the time of reduction replacing fusion tube, increase work efficiency, overcome the large danger of work high above the ground difficulty large, many people operate the safe pressure bringing, for power equipment safety operation provides Reliable guarantee.
The present invention relative to existing technologies, its beneficial effect is: high-tension fuse fingertip dismantling device provided by the invention is light, it is flexible, simple to operate to use, reduced labour intensity, reached the time of reduction replacing fusion tube, increase work efficiency, overcome the large danger of work high above the ground difficulty large, many people operate the safe pressure bringing, for power equipment safety operation provides Reliable guarantee.
