Description
Technical field
The present invention relates to a kind of specific purpose tool that detects electrical equipment or carry out high-potting, specifically 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, joint test lead-in wire needs staff to climb up 3.0 meters of high tested devices, if test lead and test connection plate are failed, contact is good, staff must again climb be connected, equipment of every test needs that staff climbs twice (primary connection, once take out stitches), not only operation is loaded down with trivial details in such operation, labour intensity is large, affect work efficiency, but also staff's safety coefficient is reduced.
Summary of the invention
The object 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 staff climbing (wiring and take out stitches convenient and simple), safeguard work personnel safely, increase work efficiency, shorten working hours etc.
The present invention is achieved by the following technical solutions:
A kind of high-altitude Insulation test jointing clamp, comprise binding clip, clamp block, goat's horn bolt and insulating bar, binding clip comprises spreader, on the post jamb of spreader, be fixed with the first clutch disk of central through hole and the first clutch disk and spreader and be positioned at same plane, one end of spreader is straight or offer tapped blind hole on the end face of the first clutch disk curving, the other end, and tapped blind hole internal thread is connected with bolt, clamp block comprises sleeve, and sleeve top vertical is fixed with the second clutch disk with center tapped through hole, the first clutch disk on binding clip aligns with the second clutch disk in clamp block and goat's horn bolt is threaded with the center tapped through hole of the second clutch disk through after the central through hole of the first clutch disk, the two is fixed together, on two faces that the first clutch disk contacts with the second clutch disk, all distinguish an equidistant uniform circle projection, bump pitch is identical with bump width, and between the circle projection on the circle projection of one on the first clutch disk and the second clutch disk, (that is: the projection on the first clutch disk is connected in the projection gap on the second clutch disk in mutual grafting interlock, projection on the second clutch disk is connected in the projection gap on the first clutch disk), insulating bar top is fixed in the sleeve of clamp block.
The projection being respectively equipped with on two faces that the first clutch disk contacts with the second clutch disk, can make the first clutch disk and the mutual interlock of the 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 the first clutch disk and the second clutch disk, and contact area is larger, and the contact resistance between the two is just less, and just less on the impact of test, the accuracy of test result is just improved.
During use, high-voltage test leads is connected on the nut of binding clip, after connecting, nut is twisted and is connected in the tapped blind hole of binding clip spreader one end, high-voltage test leads and binding clip are connected firmly, then staff only need stand on the ground and lift insulating bar, the binding clip other end is inserted hang in height on the terminal block of tested device (wherein, straight type be applicable to high-tension current inductor and voltage transformer (VT), hook type is applicable to high-voltage arrester), insert and hang up properly after binding clip, the abundant conducting of current return and voltage circuit, just can carry out high-potting.
Further, the expansion link that described insulating bar is comprised of the some sections of mutual insertings of sleeve pipe, 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 easily realize, and adjacent two sleeve pipes can be located by retention tab after pulling out, and when adjacent two sleeve pipes need to be retracted, press retention tab and are just recoverable to, very convenient.
Described insulating bar all adopts epoxy resin to make.Epoxy resin has good electrical insulating property, is one of electrically best kind of thermoset resin intermediary, has greatly improved the security of device.
On the first described clutch disk, also offer the radially gap connecting with its central through hole.Facilitate like this handling replacing of binding clip and clamp block etc.,, in the situation that goat's horn bolt needn't be back-outed completely, just binding clip can be disassembled from clamp block, convenient and swift.
The present invention's practicality reasonable in design, simple in structure, light, safe and reliable, binding clip, clamp block in the present invention are sturdy and durable, not yielding, longer service life.The present invention saves when test staff's climbing, ensured 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 the impact of surface contacted resistance has been reduced to minimum, has improved greatly the precision of test data.Jointing clamp of the present invention is portable strong, and the project organization of binding clip, clamp block, insulating bar etc. is all convenient to disassembled and assembled freely.While not using, can, by each parts dismounting, be placed in spare parts kit; During use, then each parts are are freely installed and used to easy to carry, conserve space.
