像として確認できる。As described above, since the light collecting unit 20 which is a part of the optical imaging device is incorporated in the grounding tank 1 and the light collecting unit 20 is moved, the internal inspection of the gas insulated switchgear is performed. Can be inspected while moving the light collecting unit 20 to the inspection place and viewing the internal image by the imaging device.
Further, the CCD camera is small and has little effect on the performance of the device even when it is installed in the device, and the position of the camera is relatively easily controlled from outside. In addition, it is relatively easy to take an image of the inside of a complicated pipeline, and the inspection of the internal condition can be confirmed as an image as in the visual inspection.

However, this inspection time can be reduced to within several hours. In this way, during normal inspections, it is not necessary to open gas-insulated equipment, and it is only necessary to inspect the internal conditions with images and disassemble when abnormalities are found in the equipment. Maintenance management becomes possible.
