A power cable for high-power equipment that can quickly dissipate heat

Abstract

The invention discloses a power cable for high-power equipment that can quickly dissipate heat, which includes a cable body, a filling layer and a conducting wire core. The inside of the cable body is provided with a filling layer. The sides are connected, the top and bottom ends of the power box are arc-shaped and planar structures respectively, and the inside of the power box is provided with a first valve plate, and the first valve plate is horizontally slidably connected to the outer wall of the cable body and the inner wall of the power box between. The power cable for high-power equipment that can quickly dissipate heat uses an oil pipe structure in the inner area of ​​the cable. Using multiple cavity structures in the oil pipe, the oil cooling and air cooling of the cable can be realized simultaneously, and the cooling methods are more diverse. At the same time Since the cooling structure is located inside, the cooling effect of the cable core is better, and the power source of the air cooling comes from the flow of the cooling oil itself in the oil cooling structure, and the structural design is more reasonable.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a power cable for high-power equipment that can quickly dissipate heat. Background technique [0002] Cables are an important infrastructure for power transmission. Depending on the usage scenarios, the specifications of the cables are different. During the operation and use of large-scale high-power equipment, the power and outer diameter of the power cables are large, so When this type of cable is actually used, the heat generation is also very large. In the prior art, in order to dissipate heat for the cable, air cooling or oil cooling is generally used to cool the cable. However, the existing similar power cables The following problems exist in actual use: [0003] The unreasonable design of the traditional cooling structure leads to low efficiency in reducing the temperature of the wire core in the cable body. Only oil cooling or air cooling is used unilaterally. Moreo...

Problems solved by technology

[0004] The purpose of the present invention is to provide a power cable for high-power equipment that can quickly dissipate heat, so as to solve the problem of unreasonable design of the traditional cooling structure in the above-mentioned background technology, which leads to low efficiency in reducing the temperature of the core in the cable body, and will only be adopted unilaterally. Oil-cooled or air-cooled methods, and because the heating area of ​​the cable body is concentrated in the core area of ​​the cable, the thermal conductivity of the filling area in the cable is not good, resulting in the temperature of the outer area of ​​the cable body being significantly lower than the inner temperature, and now Some cooling structures are mostly set on the surface of the cable, resulting in the problem that the core part cannot be effectively cooled
