Abstract

The invention discloses a forest fire trip test platform for a transmission line. The forest fire trip test platform consists of a voltage regulator (1), a transformer (2), a resistor (3), an electrode (4) and a grounding electrode (5) which are connected in series in sequence, wherein the electrode (4) is connected with the grounding electrode (5) in a line with an adjustable air gap-line electrode form or a rod-rod electrode form or a rod-plate electrode form; and when the voltage exceeds the tolerance level of the air gap between the electrode (4) and the grounding electrode (5), the air gap is broken down. Air gap breakdown voltage values under different conditions can be obtained through the air gap distance and the fire behavior; and the trip factors and rules of the transmission line are analyzed. The platform has the following advantages: 1) the operation is simple; 2) test contrasts under different electrode conditions are convenient; 3) test contrasts under different flame conditions are convenient; and 4) support can be provided for quantitative research of the trip factors and rules of the transmission line.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, in particular to a test platform for mountain fire tripping of power transmission lines. Background technique [0002] Forest fires occur frequently in southern my country. According to investigations, they are mostly caused by people's living customs such as sweeping graves, worshiping ancestors, burning wasteland, burning straw, and even smoking. In case of drought, the damage will be even worse. However, transmission lines usually cross areas where wildfires are prone to occur. Once a wildfire occurs, it will be the first to suffer, which can easily cause the transmission line to trip. After the transmission line tripped due to wildfires, due to the impact of insulator pollution, it is really difficult to re-close and resume power transmission, often causing power interruption or even permanent failure, seriously affecting the normal production and life of the people, and causin...
