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.
