Problems solved by technology

When the temperature is lower than 0 degrees Celsius, the wind speed is lower than 3 meters per second, and the humidity is above 75%, the surface of the contact line will be covered with ice, which will cause the locomotive to stay and even endanger the safety of locomotive operation.
In the prior art, there are usually two solutions to solve the problem of icing. One is to use machinery and labor, but the deicing efficiency is low and the effect is poor; the other is to use high current to heat the contact wire. Although it saves labor, it can be powered by long distance and high voltage. Huge energy consumption

Embodiment Construction

[0025] A heatable copper alloy contact wire, see figure 1 : It includes a contact wire body 1, a through hole 2 is arranged on the top of the contact wire body 1 in the length direction, and a heating wire 3 is arranged in the through hole 2, and the heating wire 3 includes an inner annealed copper stranded wire 4 and an outer insulating sheath 5.

[0026] The contact wire body 1 is obtained by drawing a material with a circular cross section through a tungsten steel mold;

[0027] The annealed copper stranded wire 4 of heating wire 3 is used for electrification;

[0028] The overall diameter of the heating wire 3 does not exceed 2mm.

[0029] When encountering low temperature weather, the ice coating detection sensor will transmit the line condition to the control center, and solve the ice coating problem of the external contact wire by energizing and heating the soft copper strand 4 . After testing, it only takes 20 minutes for the ice-coated contact wire to heat up from ...

Abstract

The invention provides a heatable copper alloy contact wire. A heatable soft copper twisted wire is arranged in the heatable copper alloy contact wire, through electrifying and heating the soft copper twisted wire, an icing problem of the external contact wire is solved, and small power consumption and high icing efficiency are realized. The heatable copper alloy contact wire comprises a contact wire body and is characterized in that a top portion of the contact wire body in the length direction is provided with a penetration hole, the penetration hole is internally provided with a heating wire, and the heating wire comprises the internal soft copper twisted wire and an external insulation sheath.

Description

technical field [0001] The invention relates to the technical field of electrified railway lines, in particular to a heatable copper alloy contact wire. The invention also provides a preparation method for the heatable copper alloy contact wire. Background technique [0002] The catenary wire is the main component of the electrified railway power supply system, mainly including the catenary wire and the catenary cable, which is responsible for the important task of transmitting electric energy to the electric locomotive, and plays a key role in the safe operation of the rail locomotive. Low temperature is the number one "enemy" of the contact line. When the temperature is lower than 0 degrees Celsius, the wind speed is lower than 3 meters per second, and the humidity is above 75%, ice will appear on the surface of the contact line, causing the locomotive to stay and even endanger the safety of locomotive operation. In the prior art, there are usually two solutions to solve ...
