Detailed description of the invention
Embodiment
As it is shown on figure 3, Method of Cable Trouble Point is substantially discharged device, in casing 7, it is provided with spring energy-storage motor 5, the time relay
6, binding post 1, current transformer 10 and ammeter 9, spring energy-storage motor 5 is connected with the time relay 6, and described binding post is
Telescopic mast, the outer surface of binding post is set with housing 2, and binding post 1 includes binding post A and binding post B, binding post A and binding post B
Being symmetrical arranged, one end of binding post A is provided with hard contact A, and the other end of binding post A arranges wiring hole 4 and sequentially passes through spring
Energy storage motor 5 and casing 7, one end of binding post B is provided with hard contact B, and the other end of binding post B arranges wiring hole and through case
Body, current transformer sleeved 10 on binding post B, current transformer 10 is connected with ammeter 9.
Described spring energy-storage motor is provided with supply hub 3；Described casing is provided with relay indicating light 11, closing a floodgate refers to
Show that lamp 12 and separating brake display lamp 13, relay indicating light, combined floodgate display lamp are connected with spring energy-storage motor with separating brake display lamp.
Simultaneously need to two charge and discharge devices when this utility model uses, operating process is as in figure 2 it is shown, original state is first
Second device separating brake, test starts the first device first combined floodgate 3-5 second, and transformator charges to capacitor, the fully charged rear first device of capacitor
First separating brake, second device closes a floodgate again, and capacitor discharges to failure cable, and discharge second device separating brake after terminating, a discharge cycle
Terminating, in test process, the first and second devices repeat above discharge process until locating personnel accurately finds trouble point, electric discharge device case
Body is completely insulated, safe and reliable during use, provides enough discharge energies for failure cable, makes trouble point be substantially discharged, reach
The purpose quick and precisely positioned；Operator can be replaced completely to use insulating bar repeated charge.
This utility model low-voltage cable fault is tested, concrete through as follows:
No. 1 case that certain community 2 ring main unit is carried becomes to be allotted to 3 unit low-voltage cables owing to phase fault is jumped
Lock, uses insulating bar that failure cable is repeated discharge test as it is shown in figure 1, through test after an hour, do not find event
Barrier point, is substantially discharged device to electricity by the method replacement cost utility model Method of Cable Trouble Point manually using insulating bar to discharge subsequently
After cable carries out discharge test, 20 minutes, tester have found trouble point, at 0.8 meter of ground of distance, trouble point, have seen damage
Bad cable.This device shortens the testing time of cable fault, improves the safe class in test process, reduces test
The degree-of-difficulty factor of failure cable, has obtained the favorable comment of shop floor worker.
The test of this utility model low-voltage cable fault uses temperature to be that between-10 DEG C to 40 DEG C, humidity cannot be greater than 80%.
