Abstract
The invention relates to a device for testing a cable. The device comprises an external insulation electric conductor 2, a copper earth plate 3 and an earth flexible connecting body 4. The external insulation electric conductor is installed at the position of an earth switch lower port 1, the earthing function of the earth switch lower port after passing through the device for testing the cable is achieved, then testing can be directly conducted on the device for testing the cable without demounting the cable 5 at the position of the earth switch lower port, fault points can be judged, efficiency for handling accidents on the spot is improved, the problem of man-made poor contact in the process of demounting and mounting fault cables is solved, and power supply quality is guaranteed.
Description
Technical field
The present invention relates in a kind of high-tension switch gear, cable is carried out a kind of device of fault test.
Background technology
In middle pressure power transmission and distribution switchgear, when cable breaks down, after at first the cable side grounding switch will being closed a floodgate, allow cable dead ground, can remove cable and estimate and judgement.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, small volume, fast cable tested, the failure judgement point has improved the efficient of site disposal accident, and the people is the loose contact problem that causes when having avoided the failure cable dismounting, has guaranteed power supply quality.
Technical scheme of the present invention is achieved in that a kind of cable test device, comprises that external insulation electric conductor 2, copper earth plate 3, ground connection are flexible coupling 4.The external insulation conductor is installed on grounding switch end opening 1 place, is grounded the switch end opening by grounding function behind the cable test device, need not to remove grounding switch end opening place cable 5 and just can directly do test at cable test device, the failure judgement point thereby reach.
Described insulated conductor 2 comprises conducting rod 6, insulating material 7.
Described conducting rod 6 is insulated the material parcel, only has two terminals charged.
Described insulating material 7, material can be the epoxy insulation material, also can be silicon rubber or flame-proof explosion-proof plastic material.
Described copper earth plate 3 for closing state, by being flexible coupling and the earth conducting, only has when cable need to be tested under normal circumstances, just is in a minute state, allows the external insulation electric conductor disconnect the earth.
The invention has the beneficial effects as follows:
Cable test device of the present invention, be grounded the switch end opening by grounding function behind the cable test device, thereby reach and need not to remove grounding switch end opening place cable 5 and just can directly do test at cable test device, the failure judgement point, improved the efficient of site disposal accident, the people is the loose contact problem that causes when having avoided the failure cable dismounting, has guaranteed power supply quality.
