A cylindrical arc light sensor lens

Abstract

A cylindrical arc light sensor lens, including a filter component, an optical fiber and a base, the filter component is composed of one end of a tubular part connected to the bottom of a truncated circular part, the diameter of the bottom of the circular truncated part is larger than the outer diameter of the tubular part, and the other end of the tubular part is fixed On the base; the core of the optical fiber passes through the base and the tubular part and leans against the bottom of the circular frustum; it also includes a lens, the lens is a cylinder with an opening at one end of the cavity, and the lens cover is placed on the filter On the component, one end of the opening is closed and connected with the base. The arc light sensor lens provided by the invention can increase the detection angle to 275°-300°, and can detect arc light signals of multiple detection points at the same time, thereby greatly reducing the difficulty of installation and greatly reducing the maintenance cost.

Description

technical field [0001] The invention relates to the technical field of arc light detection, in particular to a cylindrical 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.
