Rapid Icing Device for Experimental Overhead Transmission Lines

Abstract

The invention relates to a quick icing device of an overhead transmission line for an experiment. The quick icing device comprises a structural frame, a motor and a suspension wire walking wheel driven by the motor are arranged in the structural frame, wire jacking wheels are arranged on the front side and the rear side of the suspension wire walking wheel respectively and are hinged to the structural frame through supporting and lifting arms, torsional springs are arranged at the hinge positions, a liquid nitrogen storage tank and an ultrasonic vibration exciter are arranged in the structural frame, a liquid outlet of the liquid nitrogen storage tank is connected with a liquid nitrogen input opening of an icing device body through a heat preservation hose connected into a solenoid valve, a water inlet of the ultrasonic vibration exciter is connected with a water outlet of a purified water tank, a water mist outlet of the ultrasonic vibration exciter is connected with a water mist input opening of the icing device body through a heat preservation hose, the icing device body can be arranged on the transmission line in a sleeving mode, a structural body with a cavity is formed between the inner wall of the icing device body and the surface of the transmission line after the icing device body is arranged on the transmission line in the sleeving mode, and the inner wall of the icing body is coated with ice sticking preventing materials. The device can quickly ice the overhead transmission line for the experiment and is good in icing effect, and therefore accuracy of the experiment is ensured.

Description

Technical field [0001] The invention relates to a rapid icing device for an experimental overhead transmission line, which is used for quickly icing the experimental overhead transmission line to ensure the accuracy of the experiment. Background technique [0002] The icing and snow accumulation of transmission lines has long threatened the safe operation of the power system. The shedding of icing often causes major accidents such as flashover, disconnection and tower collapse of transmission line conductors, which cause serious harm to the safe operation of the power system. The UHV line has a larger conductor cross-section, the number of conductor splits is larger, and the weight of the ice coating is also greater. It is more likely to cause a larger jump during ice removal; therefore, in the design of UHV transmission lines, especially in heavy ice areas , To determine the layout of the transmission line, the selection of towers, the span configuration, etc., it is necessary t...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that it is difficult to ensure the accuracy of the experiment due to the lack of effective means of quickly icing the transmission line when carrying out the real-type experiment of icing on the transmission line, an experimental method is provided. Use the overhead transmission line fast icing device, which can quickly icing the overhead transmission line, and the icing effect is excellent
