Description

Technical Field

[0001] The invention belongs to the technical field of power system detection tools, and in particular relates to a novel spark fork device. Background Art

[0002] Insulators are one of the important components in the power grid. They are widely present in various voltage levels of the power transmission and transformation system, and the number is huge. In the operation of the grid, under the combined effects of various mechanical forces, electromagnetic field forces, and contamination and corrosion, the insulation performance of the insulators may be reduced or even fail, resulting in zero value and low value phenomena, that is, insulator degradation. Insulator degradation poses a huge safety hazard to the safe operation of the power grid. Using spark forks to detect the zero value of insulators is one of the commonly used methods. At present, the spark gap of the spark fork is fixed in multiple positions, which cannot adapt to the needs of field voltage level changes in the power grid, resulting in missed detection and false detection in the detection results. At the same time, most of the existing spark forks are handheld devices, and the operator holds the spark fork to perform live tower operations. However, due to high-altitude and live operations, the risk factor is high, the safety hazards are large, and there are many uncertain factors, which seriously threaten the personal safety of the operators. In addition, due to the different sizes of insulators of different models during detection, the fixed distance spark fork probe cannot adapt well to the changes in the size of the insulator, and the detection results will be inaccurate due to poor contact.
