Currently, increasingly serious haze pollution impairs power transmission and transformation equipment external insulation. In order to study the effect, we design a set of haze and fog simulation device based on airflow crushing system in the artificial climate chamber. The artificial climate chamber is 27.5 m high, has a diameter of 25 m, volume of 15 000 m3, which can provide an open atmospheric environment for simulating haze and fog. The simulation device is composed of two parts. One is a hot fog system in the artificial climate chamber t...
