Embodiment Construction

[0023] Under the natural state that the present invention proposes, the conducting wire icing experimental device, its structure is as follows figure 1 As shown, it includes a spray trolley 1, a magnetic field generator 2, a copper wire 3 and a wire support 5. The wire 4 to be ice-coated is erected between two wire brackets 5, the spray trolley 1 is placed on one side of the wire bracket 5, the spray trolley 1 straddles the copper wire 3, and the magnetic field generating device 2 is connected to the circuit formed by the copper wire 3 superior. The spray trolley 1 is composed of an atomizing nozzle 6, an upper arm 7, a lower arm 8, a tire 10, four magnetic field sensors 11, a water pipe 12, a water pump 13, a water tank 14, a storage battery 15 and a spray trolley controller 16. The spray trolley body 9 is erected on On the tire 10, four magnetic field sensors 11 are respectively placed at the four corners of the bottom of the spray trolley. The water tank 14, the storage b...

Abstract

The invention relates to a wire icing experimental device under the natural state and belongs to the technical field of wire experimental devices. Four wheels and a magnetic field sensor are mounted at the bottom of a vehicle body of the wire icing experimental device; a water tank, a storage battery groove and a control box are arranged at the upper part of the vehicle body; a water pump is mounted at the upper part of the water tank; an upper arm is directly mounted on the vehicle body and is hinged to a lower arm; an atomizer is mounted at the top end of the upper arm and is hinged to an upper arm bracket. A storage battery provides electric energy for the whole system; the water pump pressurizes water and enables water to be ejected out of the atomizer. According to different sags of wires subjected to an experiment, an included angle between the upper arm and the lower arm as well as between the atomizer and the upper arm can be properly adjusted, and the atomizing direction and the atomizing height can be controlled. The wire icing experimental device assists icing of the wire subjected to the experiment in a water mist spraying manner, promotes the icing efficiency, improves the icing quality, is simple in structure, high in reliability, can be adapted to more hostile environments, and can effectively ensure safety of workers when replacing manual icing.

Description

technical field [0001] The invention relates to a wire ice coating experiment device in a natural state, and belongs to the technical field of wire test devices. Background technique [0002] The icing of transmission line conductors will cause a series of problems related to mechanical and electrical properties, which seriously threatens the safe operation of lines. First, icing will increase the specific load of the conductor, causing line overload accidents, such as wire breakage or fracture, tower kinks, and foundation sinking; Deflection occurs; moreover, during the deicing process of the wire, a large dynamic tension will be generated, accompanied by deicing jump phenomenon, the large dynamic tension will damage the structure of the tower, and the deicing jump will cause phase-to-phase short circuit accidents; finally, Ice-covered conductors are prone to galloping, which is extremely harmful to the line. Therefore, it is of great significance to study the icing of tr...
