Gap discharge characteristic test platform influenced by multiple factors under simulated mountain fire condition

Abstract

The invention discloses a gap discharge characteristic test platform influenced by multiple factors under the simulated mountain fire condition. The test platform is used for simulating the practical environment of a transmission line corridor so as to obtain the breakdown characteristics of a gap under different combustion conditions, and quantitative research is further carried out on a tripping mechanism of a power transmission line under the mountain fire condition. The test platform comprises a test power source, a water resistor, a voltage divider and a sealed laboratory. A first electrode, a second electrode, a heat insulation plate, a resistor box, a weight sensor, a DV camera, a high-speed camera, an infrared thermometer, a fan, a particular generator and a signal collecting system are arranged in the sealed laboratory. By means of the gap discharge characteristic test platform influenced by the multiple factors under the simulated mountain fire condition, contrast tests of the gap under different combustion conditions can be carried out conveniently, the problem that the test factors of an existing test platform are single is solved well, and the quantitative research of the breakdown characteristics of the gap under the mountain fire condition is possible. The test platform is easy to operate, high in adaptability and capable of meeting the design requirement.

Description

[0001] technical field [0002] The invention belongs to the technical field of electrical engineering, and in particular relates to a gap discharge characteristic test platform under the influence of multiple factors under simulated mountain fire conditions. [0003] Background technique [0004] With the rapid development of my country's economy, the demand for electricity continues to grow strongly, which promotes the investment and construction of my country's power grid facilities. The construction of a large number of transmission lines has made the tension of power corridors increasingly severe, so many corridors of transmission lines are forced to be built in deep mountains with lush vegetation, and wildfires will inevitably occur in these areas. Especially in recent years, the impact of extreme weather, as well as the prevalence of customs such as burning wasteland and offering sacrifices, have caused more and more accidents of large-scale power outages caused by t...

Problems solved by technology

Therefore, it is of great significance to establish a multi-factor wildfire test platform to study the discharge characteristics of the gap under different factors; the existing wildfire test platform has too many factors, and it cannot be effectively carried out for some important influencing factors such as particles, wind speed, and fire intensity. There is no effective data acquisition and analysis system, and it is impossible to obtain comprehensive, systematic and quantitative research conclusions; in order to further quantitatively study the tripping mechanism of transmission lines under wild fire conditions, a multi-factor fusion test platform for gap discharge characteristics under wild fire conditions is proposed. Based on the test platform, the actual operating environment of the transmission line corridor can be simulated, the gap breakdown characteristics under different influencing factors can be obtained, and data support can be provided for the tripping mechanism of the transmission line under wildfire conditions
