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know and realization easily, after adjacent two sleeve pipes are pulled out, can when adjacent two sleeve pipes need be withdrawn, press retention tab and just be recoverable to through the retention tab location, and is very convenient.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 utility model practicality reasonable in design, simple in structure, light, safe and reliable, the binding clip in the utility model, pincers seats are sturdy and durable, not yielding, longer service life.The utility model saves when test staff's climbing, ensured the staff safely, alleviated labour intensity, improved work efficiency, shortened the working time.In addition, the utility model jointing clamp surface contacted resistance is little, and minimum has been reduced in the influence of surface contacted resistance, has improved the precision of test data greatly.The utility model jointing clamp 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.
