Embodiment 1

[0024] refer to figure 1 , is a structural schematic diagram of Embodiment 1 of the present invention, a sensor for monitoring the state of opening and closing of GIS isolating switch contacts, including:

[0025] A housing 1, with an opening on one side of the housing 1, and a shielding glass 2 embedded in the opening;

[0026] A collection unit, the collection unit is detachably connected in the casing 1, and the collection end of the collection unit is located on the side of the shielding glass 2;

[0027] A supplementary light unit, the supplementary light unit is arranged in the casing 1 and is located on one side of the shielding glass 2;

[0028] A control unit, the control unit is detachably connected in the casing 1, and the control unit is electrically connected with the supplementary light unit and the acquisition unit.

[0029] In actual use: the shell 1 is connected to the flange of the remote monitoring window of the GIS isolating switch, the shielding glass 2 ...

Embodiment 2

[0031] refer to figure 1 : the acquisition unit includes a lens assembly 3 and a polarizing glass-4, the lens assembly 3 and the polarizing glass-4 are detachably connected in the housing 1, and the polarizing glass-4 is located between the lens assembly 3 and the shielding glass 2 , the supplementary light unit is located at the side of the lens assembly 3 , and the control unit is located at the imaging focus of the lens assembly 3 .

[0032] In actual use: the shielding glass 2 and polarizing glass-4 can effectively eliminate the glare interference of the supplementary light source reflection, the lens assembly 3 can be used to focus, and the high-definition GIS isolating switch contact opening and closing status information can be collected through the lens, which helps to improve The accuracy of cloud analytics.

[0033] In this embodiment, the polarizing glass-4 is an orthogonal polarizing lens.

Embodiment 3

[0035] refer to figure 1 : the supplementary light unit includes an LED lamp 5, a light guide post 6 and a polarizing glass 2 7, the LED lamp 5 is arranged in a ring to form a light ring, the polarizing glass 2 7 and the light guide post 6 are in a ring structure, and the LED The lamp 5 and the polarizing glass 7 are detachably connected to the inner circumferential surface of the housing 1. The light guide column 6 is arranged between the LED lamp 5 and the polarizing glass 7. Both sides of the light guide column 6 are connected to the LED lamp 5 and the polarized light respectively Glass two 7 are bonded together, and one end of the lens assembly 3 is located in the LED lamp 5, and the LED lamp 5 is electrically connected to the control unit.

[0036] In actual use: when monitoring is required, turn on the LED lamp 5, and the LED lamp 5 conducts light guide through the light guide column 6, and then shines into the GIS isolating switch through the polarizing glass 7, the shi...

Abstract

The invention relates to the field of GIS disconnecting switches, in particular to a GIS disconnecting switch contact opening and closing state monitoring sensor which comprises a shell, wherein one side of the shell is provided with an opening, and shielding glass is embedded in the opening; an acquisition unit which is detachably connected in the shell, wherein the acquisition end of the acquisition unit is positioned on one side of the shielding glass; a light supplementing unit which is arranged in the shell and located on one side of the shielding glass; the polarized glass and the shielding glass are adopted as media for the 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 the contact metal shielding cover is effectively solved, the scattering area of the light source driven into the GIS disconnecting switch is enlarged when the LED lamp supplements light, and the light spots cannot be generated.

Description

technical field [0001] The invention relates to the field of GIS isolating switches, in particular to a sensor for monitoring the opening and closing state of contacts of GIS isolating switches. Background technique [0002] The equipment in the GIS room is a fully enclosed combined electrical appliance. The contacts of the isolating switch are sealed inside the equipment shell, and can only be manually inspected through the observation window on the side of the equipment. Directly judge the opening and closing position of the contact, and when the isolating switch is opened and closed, an extremely dazzling arc will be generated. 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 has a high voltage level and a high level of equipment safety. Any misoperation or switching failure will bring serious consequences. In order to solve the problem of difficult inspectio...
