The invention discloses a steam fog evenness adjusting device in a pollution test fog room. The steam fog evenness adjusting device in the pollution test fog room comprises an injection spray pipe, a baffle plate, an angle adjusting device, a lifting device and an inlet valve. The baffle plate is fixedly arranged on the angle adjusting device, the baffle plate horizontally covers the injection spray pipe, the angle adjusting device fixedly provided with the baffle plate is mounted on the lifting device, and the injection spray pipe is connected with an air source through an inlet valve. The lifting device can adjust the vertical position of the adjusting baffle plate and the vertical position of the angle adjusting device, and therefore the distance between the baffle plate and the injection spray pipe can be adjusted. In addition, the mounting angle of the baffle plate is adjusted through the angle adjusting device, and good fog control effects can be obtained. The steam fog evenness adjusting device in the pollution test fog room is ingenious in design, high in performance, convenient to use, and practical. The steam fog evenness adjusting device in the pollution test fog room is adopted to control fog, evener fog distribution can be obtained, and manual pollution flashover data obtained on the basis is more accurate and higher in reference values.
Description
Technical field [0001] The present invention is a kind of dirty test fog indoor steam mog uniformity adjustment device, which is a transformation technology for the dirty test fog indoor steam mog uniformity adjustment device. Background technique [0002] The dirty layer deposited on the surface of the insulator on the transmission line is under the condition of fog, exposure, and hair rain. The surface is conducting electricity, which greatly reduces the electrical strength of the insulator strings. Flash accidents may occur under the running voltage, causing the line to stick.Subtinction is an important threat to the safe operation of the power system, and the loss caused by more than 10 times the loss of lightning strikes.Therefore, the research of the decontamination characteristics of the insulators needs to be carried out and proposed measures. [0003] The occurrence of running insulators The occurrence is mainly divided into four main processes: staining, moisture, loca...
