Spherical electric-arc optical sensor lens

Abstract

The invention discloses a spherical electric-arc optical sensor lens. The spherical electric-arc optical sensor lens comprises a light filter part, an optical fiber and a base, and further comprises a lens, wherein the light filter part is formed by connecting one end of a tubular part with the bottom of a circular table part, wherein the bottom diameter of the circular table part is larger than the outer diameter of the tubular part, the other end of the tubular part is fixed on the base; a fiber core of the optical fiber penetrates through the base and the tubular part and is resisted against the bottom of the circular table part; the lens is formed by connecting the plane of the spherical notch part with one end of the column part; a cavity is further formed inside the lens, an opening is formed in the other end of the column part; the lens covers the light filter part; one opening end of the column part is in sealed connection with the base. The spherical electric-arc optical sensor lens provided by the invention can be used for increasing a detecting angle to 275-300 degrees, has a focusing function to improve arc-light detecting flexibility and can detect arc-light signals of a plurality of detecting points simultaneously, so that the mounting difficulty is greatly lowered, and the maintenance cost is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of arc light detection, in particular to a spherical arc light sensor lens. Background technique [0002] Once a fault occurs in the power system, a huge arc light will be generated. When the arc light occurs, a large amount of light energy radiation and high temperature radiation will be generated. These radiations have a great destructive effect on the power system and sometimes cause operation casualties of personnel. The degree of harm of arc light depends on the duration of arc light, so as long as the system power supply can be quickly limited or cut off, the damage caused by arc light can be effectively reduced. The arc light sensor can detect the intensity of the arc light, and then judge whether to cut off the system power according to the intensity of the arc light. At present, the arc light sensor on the market can only monitor the light signal transmitted from the fan-shaped surface about 135° ...

AI Technical Summary

Problems solved by technology

At present, the arc light sensor on the market can only monitor the light signal transmitted from the fan-shaped surface about 135° in front of it. When installing, the front of the arc light sensor lens must face the detection point to be detected. When there are multiple detection points, It is necessary to install multiple arc light sensors. If the installation is not proper, it is easy to cause the arc light from the detection point to not be received, thus failing to protect the arc light.
