Simulated bird dropping test system

Abstract

The invention relates to a simulated bird dropping test system comprising a simulated bird dropping test system auxiliary box, a simulated bird dropping test system operation platform, a sliding block guide rail, a sliding block, a bird dropping nozzle, and an optical fiber. The upper part of the simulated bird dropping test system auxiliary box is equipped with a simulated bird dropping test system control unit, a bird dropping container, and a peristaltic pump. The components inside the simulated bird dropping test system auxiliary box are connected. The bird dropping container is fixed to the left side of the bottom of the simulated bird dropping test system auxiliary box. A liquid level sensor is fixed to the center position of an upper cover of the bird dropping container. The liquid level sensor is connected with the lower end of a liquid level sensor control cable. The upper end of the liquid level sensor control cable is connected with the simulated bird dropping test system control unit. A hose fixing pipe is fixed to the inner right side of the bird dropping container. The simulated bird dropping test system of the invention can provide valuable information for the research of test data of to-ground breakdown of high voltage on a high-voltage line insulator due to a large amount of bird dropping and stable operation of a power grid.

Description

technical field [0001] The invention relates to the technical field of high-voltage power transmission operation, in particular to a test system for live simulation bird droppings test on insulators on a high-voltage transmission line. Background technique [0002] The harm of birds to power grid transmission lines is a common phenomenon. Birds naturally like to perch and play at high altitudes, especially in grassland areas, where there are no trees around for birds to perch, so transmission poles and towers have become birds. roost, which leads to frequent bird fault tripping of transmission lines. [0003] The direct cause of high-voltage line tripping is that when a bird defecates on the component above the hanging point of the insulator, the feces will fall on the skirt of the insulator. Due to the adhesion of the feces, it slides down and continues to elongate along the skirt of the insulator, resulting in The creepage distance of the insulator string is reduced. Wh...

Problems solved by technology

Another common situation is that the continuous accumulation of bird droppings on the insulators causes serious pollution on the surface of the insulators, forming a dirty layer. Under weather conditions such as fog, dew, frost, and snow, the surface conductivity of the dirty layer increases after it is wet. , the leakage current of the insulator increases sharply, generating partial discharge and developing into flashing along the surface, causing a ground fault and tripping

Another situation is that when the big bird staying on the pole tower is playing or taking off, the distance between the wire and the pole tower and the cross arm is not enough, and it is directly discharged, causing a ground fault and tripping
