Abstract

The invention discloses a conducting wire ice coating increase regularity testing device for an electric transmission line, which includes a current booster (1), a modulating control system (2), a thermoscope (3) and a conducting wire (4), wherein the modulating control system (2) is electrically connected with the current booster (1); the conducting wire (4) penetrates a center hole (11) of the current booster (1) and forms a circle; and the thermoscope (3) is superimposed on the conducting wire (4). During the use, the device can be used immediately after being arranged at the center of a pre-arranged phytotron; the current booster (1) utilizes the electromagnetic induction for current boosting for the conducting wire (4), the modulating control system (2) is used for modulating the current intensity, and the thermoscope (3) is used for monitoring the temperature of the conducting wire and avoids over temperature; and the device is used for performing the ice coating increase experiment for the conducting wire under a running current, lays a good foundation for mastering the ice coating increase regularity for the conducting wire, has a simple structure, is convenient to operate, flexible in modulation and safe in operation, and causes no danger for persons and equipment.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a test device for the growth law of ice coating on transmission line conductors. Background technique [0002] The icing of transmission line conductors seriously threatens the safe and stable operation of the power grid. During the ice disaster in the southern region in 2008, many power transmission lines collapsed due to icing, and wires were disconnected, causing large-scale power outages and posing a serious threat to the production and life of the people. [0003] In order to effectively combat ice and snow disasters, it is necessary to grasp the relationship between the ice growth law of transmission lines under operating current and meteorological parameters such as temperature, rainfall, and wind speed. Based on this growth law, combined with the forecast conclusions of meteorological parameters such as temperature, rainfall, and wind speed, it...
