Embodiment

[0056] The overall structure of the infrared sulfur hexafluoride leak detection camera is composed of three parts: the radiation source 1 of the VT infrared radiation generator, the spectrum discrimination selector 2, and the infrared camera 3.

[0057] The working process of this infrared sulfur hexafluoride leak detection camera is described as follows: first, after the infrared camera 3 control switch 41 is turned on and energized, the external power supply is connected to the VT infrared radiation generator radiation through the power socket 40 and the wire 14 of the VT infrared radiation generator. The electric heating film 13 on the inner layer of the illumination source is heated by electricity; when the temperature of the ceramic substrate 11 reaches about 200°C, the heated high-emissivity infrared radiation material coating 12 will be heated according to its spectral characteristics. image 3 , with an emissivity as high as 0.9 or more, it produces a large amount of in...

Abstract

An infrared sulfur hexafluoride leak-detecting camera belongs to the technical field of gas leak-detecting instrument. The characteristics are that the infrared sulfur hexafluoride leak-detecting camera comprises an electronically connected VT infrared radiating generator, a spectrum identifying selector and an infrared camera; the VT infrared radiating generator can generates the infrared lines which absorb the wavelength of the sulfur hexafluoride molecule, which is used being the radiating source of the sulfur hexafluoride gas. The invention is unnecessary to processes the use of all similar equipment at home and abroad are essential for laser, which has a simple structure, low cost for achieving the visual detection for the leakage of the SF6.

Description

technical field [0001] The present invention relates to an instrument for detecting gas leakage, more precisely a sulfur hexafluoride (SF 6 ) When the gas leaks, the infrared technology is used to find the leak location in time and directly display it with visible images. [0002] Sulfur hexafluoride (SF 6 ) gas is an insulating medium used in high-voltage circuit breakers and switchgear, and is increasingly widely used in power transmission and transformation systems; once a leak occurs, it will cause harm to the environment and personnel; timely detection of SF 6 Leakage is of great significance to the normal and stable operation of the power system. Sulfur hexafluoride (SF 6 ) The gas itself is colorless and odorless, and the traditional leak detection method cannot directly determine the location of the leak; the newer technology uses laser irradiation for infrared imaging, but the laser is expensive and bulky. The present invention is used with SF 6 Molecular spectra...
