Description
Technical field
The present invention relates to a kind of specific purpose tool that detects electrical equipment or carry out high-potting, specifically is a kind of high-altitude Insulation test jointing clamp.
Background technology
The current transformer of transformer station, voltage transformer (VT), lightning arrester etc. are in spring inspection preventive trial and repair based on condition of component routine test process; Connecting test lead needs the staff to climb up 3.0 meters high tested devices; If test lead and test connection plate fail contact well, the staff must climb once more be connected, equipment of every test needs that the staff climbs twice (primary connection, once take out stitches), not only operation is loaded down with trivial details in such operation; Labour intensity is big; Influence work efficiency, but also staff's safety coefficient is reduced.
Summary of the invention
The objective of the invention is for a kind of high-altitude Insulation test jointing clamp is provided; When testing of equipment, this test jointing clamp can save the staff climbing (wiring and take out stitches convenient and simple), safeguard work personnel safely, increase work efficiency, shorten working hours etc.
The present invention realizes through following technical scheme:
A kind of high-altitude Insulation test jointing clamp; Comprise binding clip, pincers seat; Goat's horn bolt and insulating bar, binding clip comprises spreader, first clutch disk and first clutch disk and the spreader that are fixed with the band central through hole on the post jamb of spreader are positioned at same plane; One end of spreader is straight or on the end face of first clutch disk, one lateral bending song, the other end, offer tapped blind hole, and the tapped blind hole internal thread is connected with bolt; The pincers seat comprises that sleeve, sleeve top vertically are fixed with second clutch disk of band center tapped through hole; First clutch disk on the binding clip align with second clutch disk on the pincers seats and the goat's horn bolt passed the central through hole of first clutch disk after be threaded with the center tapped through hole of second clutch disk; The two is fixed together; On contacted two faces of first clutch disk and second clutch disk all respectively equidistance be uniformly distributed with one the circle projection; Bump pitch is identical with bump width; And grafting interlock (that is: the projection on first clutch disk is connected in the projection gap on second clutch disk, and the projection on second clutch disk is connected in the projection gap on first clutch disk) each other between the circle projection on the circle projection of one on first clutch disk and second clutch disk; The insulating bar top is fixed in the sleeve of pincers seat.
The projection that is respectively equipped with on contacted two faces of first clutch disk and second clutch disk can make first clutch disk and the mutual interlock of second clutch disk on the one hand, and contact is good, difficult drop-off; On the other hand, the interlock setting of projection has increased the contact area between first clutch disk and second clutch disk, and contact area is big more, and the contact resistance between the two is just more little, and just more little to the influence of test, the accuracy of test result just is improved.
During use, high-potting lead-in wire is connected on the nut of binding clip, after connecting nut is twisted and be connected in the tapped blind hole of binding clip spreader one end; The high-potting lead-in wire is connected firmly with binding clip; The staff only need stand in and on the ground lift insulating bar then, makes the binding clip other end insert on the terminal block of the tested device of hanging in height that (wherein, straight type is applicable to high-tension current inductor and voltage transformer (VT); Hook type is applicable to high-voltage arrester); Insert hang up properly binding clip after, the abundant conducting of current return and voltage circuit just can carry out high-potting.
Further, described insulating bar overlaps the expansion link of inserting and forming each other by some sections sleeve pipes, is provided with retention tab between adjacent two sleeve pipes.Insulating bar is designed to flexible shape, freely more convenient to use, can carry out adjustment at any time according to the true altitude of equipment under test, conserve space, time, improved work efficiency.Retention tab is prior art (as shown in Figure 9), is that those skilled in the art know and realization easily, after adjacent two sleeve pipes are pulled out, can when adjacent two sleeve pipes need be withdrawn, press retention tab and just be recoverable to through the retention tab location, and is very convenient.
Described insulating bar all adopts epoxy resin to process.Epoxy resin has excellent electric insulation property, is one of best kind of dielectricity in the thermoset resin, has improved the security of device greatly.
Also offer the radially gap that connects with its central through hole on described first clutch disk.Make things convenient for the loading and unloading replacing of binding clip and pincers seats etc. like this, promptly under the goat's horn bolt needn't be back-outed the situation of coming fully, just can binding clip be disassembled from pincers, convenient and swift.
The present invention's practicality reasonable in design, simple in structure, light, safe and reliable, the binding clip among the present invention, pincers seats are sturdy and durable, not yielding, longer service life.The present invention saves when test staff's climbing, ensured the staff safely, alleviated labour intensity, improved work efficiency, shortened the working time.In addition, jointing clamp surface contacted resistance of the present invention is little, and minimum has been reduced in the influence of surface contacted resistance, has improved the precision of test data greatly.Jointing clamp of the present invention is portable strong, and the project organization of binding clip, pincers seat, insulating bar etc. all is convenient to disassembled and assembled freely.Can each parts dismounting be placed in the spare parts kit when not using; During use, again each parts is is freely installed and used easy to carry, conserve space.
