Estimating the term…
A simulation equipment for hot and humid marine environment and radiation intensity prediction method thereof, which can simultaneously load the working environment factors including voltage, current, temperature, humidity, salt spray, and UV radiation for the tested electrical equipment. The radiation intensity prediction method can predict the UV radiation intensity at the target position of the tested electrical equipment under the influence of different temperature and humidity and salt spray concentration on the attenuation of UV light radiation, so as to accurately obtain the UV radiation intensity qt at the target position of the tested electrical equipment during material corrosion and aging tests. Moreover, the UV radiation intensity qt at the target position of the tested electrical equipment can be adjusted to the target UV radiation intensity by correspondingly enhancing or weakening the luminous intensity of each UV fluorescent lamp tube.
A simulation equipment for a hot and humid marine environment, comprising a dry salt spray generation device, a humidifier, a salt spray generation chamber, a main test chamber, and a temperature and humidity regulation system, the dry salt spray generation device is capable of delivering micro-nano scale sodium chloride dry salt particles into the salt spray generation chamber, the humidifier is capable of delivering moist air into the salt spray generation chamber, a centrifugal fan is installed in the salt spray generation chamber, and an outlet of the centrifugal fan is connected to an air inlet of the main test chamber, and the air inlet is located at an upper part of a side wall of the main test chamber;
