A comprehensive test platform for mountain fire tripping of transmission lines

Abstract

The present invention relates to the field of electrical engineering technology and particularly relates to a transmission line mountain fire trip integrated test platform which comprises a wire-to-ground discharge test chamber, an insulator temperature rise performance trip test chamber and a wire-to-tower discharge test chamber. The wire-to-ground discharge test chamber and the insulator temperature rise performance trip test chamber are electrically connected to the wire-to-tower discharge test chamber through wires. An inner layer closed chamber door 1 is arranged between the wire-to-ground discharge test chamber and the insulator temperature rise performance trip test chamber. An inner layer closed chamber door 2 is arranged between the insulator temperature rise performance trip test chamber and the wire-to-tower discharge test chamber. The wire-to-ground discharge test chamber, the insulator temperature rise performance trip test chamber and the wire-to-tower discharge test chamber are provided with air inlets and air outlets. According to the transmission line mountain fire trip integrated test platform, the problem of a single line trip test platform form in an existing mountain fire condition is solved, and a lot of different types of data supports are provided for the research of a transmission line mountain fire trip mechanism.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a comprehensive test platform for mountain fire tripping of power transmission lines. Background technique [0002] Transmission line is a kind of power transmission equipment exposed to the wild environment for a long time. Lush vegetation grows under many transmission line corridors, so wildfires will inevitably occur around the transmission line. There are more and more accidents caused by large-scale power outages caused by wildfire trips, seriously affecting the reliability of power supply. [0003] Line wildfire trips are usually caused by breakdown of conductor air gaps or damage to insulators. The breakdown of the air gap usually has two discharge forms: the discharge of the wire to the ground, and the discharge of the wire to the tower. The existing research results show that the tripping of transmission lines under wildfire conditions is mainly related ...
