Abstract

The invention relates to a three-dimensional real-time observation device of an electrical tree initiation experiment based on binocular vision. The three-dimensional real-time observation device comprises a first observation group, oil grooves, a second observation group and copper electrodes. Two mutually perpendicular slide rails are provided with the first observation group and the second observation group. A first object lens is installed in front of a first camera. A first eye lens is installed in front of the first object lens. A first light converging lens is installed in front of the first eye lens. A first light source is installed in front of the first light converging lens. A second object lens is installed in front of a second camera. A second eye lens is installed in front of the second object lens. A second light converging lens is installed in front of the second eye lens. A second light source is installed in front of the second light converging lens. The oil grooves are installed between the first light converging lens and the first eye lens and between the second eye lens and the second light converging lens respectively. The copper electrodes are arranged above the oil grooves. According to the electrical tree real-time observation device, the three-dimensional image of electrical tree growth can be observed in real time so that the three-dimensional image can further realistically and accurately represent the characteristics of electrical tree growth in comparison with the two-dimensional image.

Description

technical field [0001] The invention relates to an observation device, in particular to a three-dimensional real-time observation device for an electrical dendrite induction experiment based on binocular vision. Background technique [0002] With the development of high-voltage transmission network, new requirements are put forward for high-voltage transmission cables, and cable materials with higher withstand voltage levels are required. Electric tree branching is an important phenomenon in the cable aging process. To study the treeing and growth characteristics of electric tree branches, is of great significance. Existing observation devices for electric dendrite initiation generally adopt a microscopic camera for real-time observation. The sample is in the form of a sheet, and a needle is inserted to initiate with needle-plate electrodes. The observed result of the existing device is a two-dimensional image, but the actually induced electric tree is a three-dimensional o...
