It is frequently necessary to change section containing defective cable during the experiment of high-tension cable defects simulation, and ordinary test is set
Meter does not all take quarantine measures to separate defective cable section and non-defective cut cable, causes that each Renewal process workload is big, the cycle
Long and waste test material.
When carrying out high-tension cable experiment, cable termination uses Open architecture mostly, and typically metal is used between terminal
Wire is attached.Open terminal volume is huge and requires higher to safe distance, causes laboratory space larger,
Experimentation cost is high.Meanwhile need to change the cut cable of existing defects after the completion of experiment, if whole using open cable
End, replacing workload is big, the cycle is long and replacement cost is higher.
Utility model content
Technical problem to be solved in the utility model is the defects of overcoming above-mentioned prior art to exist, there is provided one kind leans against
Back of the body formula GIS high-voltage cable connecting devices, it is used to separating the defects of high-tension cable defects simulation experiment cut cable and non-defective
Cut cable, it is easy to the replacing to defective cable section during experiment, with cost-effective, raising test efficiency.
Therefore, the utility model adopts the following technical scheme that：One kind experiment back-to-back type GIS high-tension cables connection dress
Put, including a GIS warehouses and two hv cable terminations, two described hv cable terminations are inserted respectively from the both sides of GIS warehouses
Enter in GIS warehouses, two conductor connecting shafts of two hv cable terminations carry out fastening pair using demountable structure in GIS warehouses
Connect.
The utility model carries out fastening docking using demountable structure to the conductor connecting shaft of two hv cable terminations, can be real
The now isolation of experiment defective cable section, it is easy to change defective cable during experiment, it is cost-effective, improve test efficiency.
As the supplement of above-mentioned technical proposal, described demountable structure includes an anchor ear, at least two bolts and and spiral shell
The corresponding nut of bolt quantity, described anchor ear are embraced on two conductor connecting shaft outer ends, and screw bolt and nut is used to embrace anchor ear
Tightly in conductor connecting shaft., can the fast quick-detach of defective cable section and replacing during experiment using such a demountable structure.
As the supplement of above-mentioned technical proposal, described anchor ear is formed by connecting by two metal splint pairings, two metal splints
Be in semi-annular shape, the both ends outward bendings of two metal splints respectively forms a mounting ear, the mounting ear of a metal splint with it is another
The corresponding mounting ear of one metal splint is docked using screw bolt and nut.
As the supplement of above-mentioned technical proposal, the outside of the demountable structure is equipped with a metallic shield.Metallic shield
The electric field for equalization conductor connecting shaft joint is covered, meets the requirement without background partial discharge during experiment.
As the supplement of above-mentioned technical proposal, described metallic shield is cylindrical.
The utility model has the advantage that as follows：The utility model is a kind of clever structure, is easily changed cable
Back-to-back type GIS high-voltage cable connecting devices, docking site use demountable structure, can be achieved experiment with defective cable section every
From, be easy to change defective cable during experiment, can greatly lifting test efficiency, save experimentation cost.
