The concrete mount scheme of described observation window and video probe can be: the glass pane of described observation window, be fixed in the observation window position of opening of described tank body by a cover plate for sealing; This cover plate radially is provided with through hole; Non-observation window one side of this cover plate with inlay card, screw thread or in other dismountable mode, is covered with a protective cover; Described video probe and/or floor light light source are installed on the inboard of described protective cover.
As the improvement to such scheme, this port visual device also includes the video frequency divider; The signal input part of this video frequency divider connects described video probe, and its signal output part connects the monitoring display unit of convergence control cabinet or master-control room.
Preferably, described floor light light source adopts LED, and its supply power voltage is low, electric current is little, and but brightness height, life-span are long, and 2-5W can satisfy instructions for use.
Described video probe can adopt the low-light (level) camera.
The utility model gas-insulated enclosed type high pressure isolating/grounding switch, on the grounded metal housing, set up observation window, the low-light (level) camera is installed in the inspection hole position, by video probe with switch service position real-time Transmission to convergence control cabinet, or be uploaded to master-control room by video adapting, realize the real-time monitoring of operating personnel's switching devices operation conditions in safe range.Can clearly see the isolating/grounding switch position at convergence control cabinet display or backstage after device puts into operation, it will become the important servicing unit of the safe operation of HGIS.
In addition, utilize the video frequency divider, also the some groups of cameras and the LED illumination of several tank bodies of each switch (single mother or two mother) can be formed a system, by frequency divider these a plurality of camera lens pictures are simultaneously displayed on the display, thereby, the operator can observe the operating state of isolation knife in these several tank bodies simultaneously by display, understands the working condition of equipment more intuitively, guarantees safe operation.
