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.

Abstract

The invention relates to the field of high-voltage switch equipment in an electric power system, in particular to a light supplementing device and method for monitoring the on-off state of a GIS disconnecting switch contact. The device comprises a remote observation window and a visual observation window of a GIS disconnecting switch; a light guide part which is detachably connected to the remote observation window; a light source which is detachably connected to the light guide part, and is diffused into the GIS disconnecting switch through the light guide part; and a linked switch which is linked with the visual observation window, and is electrically connected with the light source. According to the invention, a polaroid is adopted as a medium for an LED lamp light source to enter the GIS disconnecting switch, so that the problem that the light source can reflect light spots on the remote observation window glass and a contact metal shielding cover is effectively solved, the scattering area of the light source shot into the GIS disconnecting switch is expanded when the LED lamp is used for supplementing light, and meanwhile, the light spots are not generated.

Description

technical field [0001] The invention relates to the field of high-voltage switchgear in a power system, in particular to a supplementary light device and method for monitoring the opening and closing state of contacts of a GIS isolating switch. Background technique [0002] The equipment in the GIS room is a fully enclosed combined electrical appliance. The switch contacts are sealed inside the equipment and can only be manually inspected through the observation window on the side of the equipment. In the opening and closing position of the isolating switch, extremely dazzling arc light will be generated when the isolating switch is opened and closed. Relying on the conventional manual point-by-point visual inspection method is time-consuming and extremely inconvenient and unsafe, especially on UHV GIS, UHV GIS The voltage level is high and the equipment safety level is high. Once there is a misoperation or a switching failure, it will bring serious consequences. In order t...
