Abstract

The invention relates to a test system suitable for researching a deicing fault of a multilevel power transmission wire. The test system comprises a wire shrinkage ration module, a deicing control module, a tensile force measuring module, a monocular camera module and a calculation processing module, wherein the wire shrinkage ratio module comprises a long rope, fixed supports fixed on two ends ofthe long rope, and a traction support disposed between the fixed supports and used for hanging the long rope; the deicing control module comprises a relay and an electromagnet; the tensile force measuring module comprises a tensile force sensor and a dynamic strain instrument; the monocular camera module comprises a high-speed camera, a calibration plate and a marker; and the calculation processing module comprises a processor connected with the camera and the dynamic strain instrument. The test system has the beneficial effects that multiple parameters are adjustable, and the applicable research range is wide; the breakthrough in the field based on scale model test research from scratch can be achieved, and the significance for prompting relevant researches can be achieved; and the testsystem can be built in a room, and is convenient to install, easy for processing components and high in practicability.

Description

technical field [0001] The application belongs to the technical field of power transmission and distribution, and in particular relates to a test system suitable for research on de-icing faults of multi-speed transmission wires. Background technique [0002] Icing of transmission lines refers to a natural phenomenon in which moisture or rainfall in the air freezes to form frost. Under certain natural conditions such as temperature and wind, the falling off of the ice coating on the transmission line will cause the line to vibrate up and down and swing laterally, which is also called "ice jump" in engineering. During the de-icing and jumping process of the transmission line, the gaps between the conductors of each phase and between the conductors and the ground wire may be smaller than the corresponding insulation gap requirements, resulting in electrical accidents such as phase-to-phase flashover, tripping, and burning wires, and even due to severe wire tension Changes caus...
