Problems solved by technology
However, when the existing infrared imager detects gas, the imaging of the background object is weakened, so that the whole picture has no sense of hierarchy, and it is difficult to distinguish the specific location of the leak point
[0006] Therefore, the prior art has the defect of being unable to accurately find the SF6 leakage point

Embodiment approach
[0042] As an optional implementation manner, the main controller includes:
[0043] an infrared detection unit, configured to connect with the infrared detector, and analyze and obtain the exposure characteristics of the infrared detector;
[0044] A switch bracket monitoring unit, connected to the encoder, used to receive the encoder output signal and obtain the current angular displacement information of the switch bracket;
[0045] The motor control unit is connected to the motor and the infrared detection unit respectively, and is used to obtain the exposure characteristics of the infrared detector obtained by the infrared detection unit and the current angle of the switch bracket obtained by the switch bracket monitoring unit. The displacement information controls the rotation of the motor, so that the filter on the switching bracket accurately appears on the center of the optical path of the infrared lens at the shooting time point of the infrared lens;
[0046] The inf...

The invention discloses an infrared thermal imager, which comprises a base, an infrared core mounted on the base, a multi-filter switching mechanism and an infrared lens, and the infrared core controls the multi-filter switching mechanism Switching is performed on the optical path of the infrared lens, so that the infrared lens respectively shoots the background image of the gas cloud before and after being filtered by the optical filter, and performs fusion imaging on the background image of the gas cloud before and after filtering by the optical filter . Therefore, the infrared thermal imaging camera of the present invention can strengthen the imaging of background objects, make the whole picture more layered, and easily distinguish the specific position of the SF6 leakage point. Therefore, the use of the infrared thermal imager of the present invention can accurately find the SF6 leakage point.
Description
technical field [0001] The invention relates to the technical field of infrared imaging, in particular to a cooling infrared thermal imager. Background technique [0002] With the development of the electric power industry, SF6 is widely used in high-voltage circuit breakers and substation equipment in the electric power industry all over the world as the superior insulation of the pole base and the arc-extinguishing medium. Today, it is almost the only insulating medium in high voltage and extra high voltage circuit breakers and GIS. Pure SF6 gas is colorless, odorless, non-combustible, and its chemical properties are particularly stable at room temperature, with a specific gravity more than five times that of air. However, in the power system, under the influence of arc partial discharge, high temperature and other factors, SF6 gas will decompose. Its decomposition products will generate corrosive electrolytes when they meet with water, especially some highly toxic decom...
