Problems solved by technology

[0002] In the hot and humid marine environment, the operating environment of electrical equipment is complex, and the high temperature, high humidity, high radiation, and high salt spray conditions lead to the problem of premature failure of electrical products that has always existed and even become more and more serious
The design and development of equipment that can load the above environmental factors at the same time needs to answer the question of the influence mechanism of different temperature, humidity and salt spray concentration on the intensity of ultraviolet radiation. When there is salt spray in the test chamber, after starting the ultraviolet light source, the ultraviolet radiation Due to the existence of salt spray droplets in the main test chamber, phenomena such as scattering, reflection, absorption, and transmission will occur, which will lead to different degrees of radiation intensity at various positions in the internal space than that at the emission point of the light source.

Abstract

The invention discloses a humid and hot marine environment simulation device and an irradiation intensity prediction method thereof, which can simultaneously and synergistically load working environment factors including voltage, current, temperature and humidity, salt mist and ultraviolet irradiation for electrical equipment to be tested, accurately simulate a working operation state of the electrical equipment to be tested in a humid and hot marine environment, so accuracy of material corrosion, aging and other tests on the tested electrical equipment is improved. According to the irradiation intensity prediction method provided by the invention, ultraviolet irradiation intensity of the target position of the detected electrical equipment under the influence of different temperature, humidity and salt mist concentration on ultraviolet irradiation attenuation can be predicted; therefore, ultraviolet radiation intensity of the target position of the tested electrical equipment can be accurately obtained during material corrosion and aging tests; by correspondingly enhancing or weakening luminous intensity of each ultraviolet fluorescent lamp tube, ultraviolet radiation intensity of the target position of the detected electrical equipment can be adjusted to the target ultraviolet radiation intensity.

Description

technical field [0001] The invention relates to material corrosion and aging equipment, in particular to a humid-heat marine environment simulation equipment and a radiation intensity prediction method thereof. Background technique [0002] In the humid and hot marine environment, the operating environment of electrical equipment is complex, and the high temperature, high humidity, high radiation, and high salt spray conditions lead to the problem of premature failure of electrical products that has always existed and even become more and more serious. However, the existing indoor environment simulation test equipment is loaded with a single environmental factor, which cannot accurately simulate the influence of various environmental factors in the marine atmospheric environment on the corrosion and aging of electrical equipment. Therefore, it is very important to design and develop multi-factor coupling equipment for simulating the hot and humid marine environment, which ca...
