Described annex mainly is made up of conductive sleeve that cooperatively interacts and conducting rod, the end that is fixed on the left cable of left side on the stand conductive sleeve of packing into, conductive sleeve left end endoporus is inserted in left cable core, the insulation end face of its left side and left cable is fitted and is locked by double-screw bolt, and the right-hand member of conductive sleeve is preset with the hole of matching and inserting with conducting rod; Be fixed on right cable end on the stand of the right side conducting rod of packing into, conducting rod right-hand member endoporus is inserted in right cable core, the insulation end face of its right side and right cable is fitted, and be locked by double-screw bolt, the left end of conducting rod forms the right cylinder that matches and insert with conductive sleeve, this right cylinder is provided with groove, and the multiconductor element is housed in the groove.
The utility model has solved and can't be inserted in the difficult problem that cable is tested by easily that internal diameter is little than cable size prefabricated high voltage power cable straight coupling and isolating joint after adopting said structure, reached convenient test, simply, effect efficiently.
Description of drawings:
Accompanying drawing 1 is the structural representation of right side of the present utility model stand;
Structural representation when accompanying drawing 2 is the left and right cable of the utility model by annex and joint assembling;
Structural representation when accompanying drawing 3 is the utility model right side cable by conducting rod and joint assembling;
Accompanying drawing 4 is the structural representation (clear for expression, the spy moves to the cable top with joint, and in fact they are coaxial) that conductive sleeve and conducting rod cooperatively interact.
Embodiment:
Below in conjunction with a preferred embodiment and accompanying drawing thereof the utility model is described further,
See shown in the accompanying drawing 1, lay two guide rails 8 on the frame 12, and guide rail plate 10, platen 9 is fixed on the guide rail plate 10, and handwheel 11 is connected with platen 9 by mechanical transmission mechanism 3, shakes handwheel 11 and can drive platen 9 side-to-side movements.Two cable grips of being made up of two halves 4 are fixed on cable D on the platen 9 by spring 5, screw rod nut 6.The baffle plate of being made up of two halves 1 can separate, and allows underproof joint J put into or to take out.The position of baffle plate 1 on bracing frame 2 can be done among a small circle and be regulated.Underproof joint J is shelved on the baffle plate 1, and contact (the baffle plate figure that contacts with end face B is not shown) of its two supporting surface A, B and baffle plate 1 can be realized by the position of suitable adjusting bracing frame 2.Underproof joint J should regulate coaxially with cable D.Thereby shaking handwheel 11 can drive platen 9 and drive cable D and insert joint J or therefrom extract.
For test tested joint J, on the end of cable D and cable core thereof, some cable accessories to be installed, see shown in accompanying drawing 2, the accompanying drawing 3.The conductive sleeve 15 made of copper of packing in the end of left cable D, its left end endoporus is inserted in left cable core, makes the end face of its left side and left cable insulation fit, and it is locked and regulates coaxially with left cable D with screw.The conductive sleeve right-hand member has a hole that cooperates with conducting rod 17 left end barrel portions made of copper.The left end column part of conducting rod 17 is provided with a groove, and multiconductor element 16 is mounted thereto.(cooperating with the conducting rod 17 left ends) hole and the conducting rod 17 of multiconductor element 16 and conductive sleeve right-hand member contact, and what keep conductive sleeve 15, conducting rod 17 is electrically connected and makes it easy slip.The same with conductive sleeve 15, conducting rod 17 also is inserted in right cable core with its right-hand member endoporus, and the insulation end face of its right side and right cable is fitted, and is fixed and regulates coaxially with right cable D with screw.Two handwheels 11 about shaking, left and right sides cable and conductive sleeve 15, multiconductor element 16, conducting rod 17 become a cable (seeing shown in the accompanying drawing 4) after cooperating.
During use,, establish a mark 14 (for example with PVC tape around several circles, see accompanying drawing 4) in the appropriate location of cable D according to the product structure of joint J of test.When install joint J by Fig. 1, become a cable after two handwheels 11 stretch into underproof joint J and cooperation with left and right sides cable D about shaking.See shown in the accompanying drawing 4, mark 14 aligns with the end face of joint J, the mid point of joint J axial dimension A should overlap with the mid point of axial dimension L after conductive sleeve 15 conducting rods 17 cooperate, at this moment, conductive sleeve 15, conducting rod 17 external diameters (the same with the cable insulation external diameter) overlap with the high-tension shielding in underproof joint J and contact.Like this by testing routine, with copper mesh and appropriate ground connection, add high voltage in the external packets of joint J at the far-end (scheming not shown) of cable D, can test.After the test, extract from joint J thereby shake two handwheels, 11 drive cable D.
