Embodiment 1
[0027] Referring to Figures 1 to 2, it is a schematic structural diagram of Embodiment 1 of the present invention, a supplementary light device for monitoring the opening and closing state of a GIS isolating switch, including:
[0028] Remote observation window 1 and visual observation window 2 of GIS isolating switch;
[0029] A light guide part, which is detachably connected to the remote observation window 1;
[0030] A light source, the light source is detachably connected to the light guide part, and the light source diffuses into the GIS isolating switch through the light guide part;
[0031] A linkage switch 3, the linkage switch 3 is linked with the visual observation window 2, and the linkage switch 3 is electrically connected with the light source.
[0032] In actual use: the light source illuminates the inside of the GIS isolating switch through the light guide part to provide sufficient brightness for the sensor, and guides the light source through the light guide...
Embodiment 2
[0036] refer to figure 2 , the difference of this embodiment is that: the light guide part is a polarizer 4, the polarizer 4 has a ring structure, one side of the polarizer 4 is detachably connected to a light source, and the other side of the polarizer 4 is connected to The outer side of the remote viewing window 1 is detachably connected.
[0037] In actual use: the polarizer 4 is used as the light guide part, the light source passes through the polarizer 4 so that no light spots are formed, and the slow reflection area is diffused so that there will be no concentrated reflection of the light source in the GIS isolating switch.
Embodiment 3
[0039] refer to figure 2 , The difference of this embodiment is that: the inner peripheral surface of the polarizer 4 is covered with a light-shielding layer 5 .
[0040] In actual use: the light-shielding layer 5 can prevent the sensor at the center from being directly affected, and prevent the image from shining.
