| 摘要 |
The invention refers to a method for on-site X-ray inspection of a cable sealing end termination of a high-voltage cable in joint condition, such as found when inspecting gas insulated switchgear of electrical high voltage sub-stations, comprising the following steps:
- providing a radiation generator (8) capable of emitting upon energization electromagnetic waves with a wave length and a photon energy in the x-ray range,
- providing a photographic recording media (9) sensitive to the electromagnetic waves,
- placing the recording media (9) and the radiation generator (8) at opposite sides of the cable sealing end termination such that the radiation generator (8) is directed towards the cable sealing end termination as a x-ray target,
- energizing the radiation generator (8) at least once in order to record at least one x-ray image,
- providing at least one reference image of a cable sealing end termination as a test target,
- comparing the x-ray image with the reference image and subsequently assessing the sealing integrity of the cable sealing end termination. |
