Abstract

The invention relates to detection devices and particularly relates to a composite insulator hydrophobicity detection device. The detection device includes a detection device frame, an air ventilator, an insulator, and an insulator base. A moving door, a water pump, a water tank and the air ventilator are arranged on the detection device frame. The insulator base is arranged inside the detection device frame and is connected to the insulator. The detection device is convenient to install and has low cost, which is much lower than that of similar products on market, due to the mechanical structures. For different types of the insulators, corresponding structural heights of the device are different, wherein the optimized structural height of the device can reach 100 cm, so that the detection device can adapt a wide range of insulators and can detect composite insulators in various electric systems. The detection device can standardize detection environment and greatly improves detection accuracy. In the image processing field, non-uniformity of illumination is a common difficult issue; the detection device can improve illumination environment for image processing to certain degree by using an annular light source and controlling illumination distance, thus reducing influence due to the non-uniformity of illumination.

Description

technical field [0001] The invention relates to a detection device, in particular to a composite insulator hydrophobicity detection device. Background technique [0002] At present, composite insulators are widely used in electrified railways and power grids due to their many advantages. When pollution flashover occurs, it will have a serious impact on the operation of the railway, which may force the locomotive to stop, or even damage the catenary wire, seriously affecting the safety of the railway operation; for the transmission line, it may cause the line to trip, causing serious Economic losses. With the help of hydrophobicity grade judgment, the possibility of pollution flashover of insulators can be more accurately evaluated, so as to determine whether the insulator can continue to be used. At present, during the detection process of related instruments for testing the hydrophobicity of uncharged composite insulators, most insulators are exposed to the external envir...
