Embodiment Construction

[0020] The preferred embodiments are given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0021] Such as figure 1 and 2 As shown, the evaporative internal cooling multi-core cable circulation system of this embodiment includes a cable 1, an evaporating tank 2, a vacuum pump group 3, a pressure gauge 4, an evaporating connecting pipe 5, a return pipe 6, an evaporating envelope 7, a return envelope 8 and cooling Liquid 9.

[0022] One end of the cable 1 communicates with the evaporation tank 2 through the evaporation connecting pipe 5 , and the evaporation tank 2 communicates with the other end of the cable 1 through the return pipe 6 . The evaporation connection pipe 5 and the evaporation tank 2 are sealed by an evaporation envelope 7 , and the return pipe 6 and the evaporation tank 2 are sealed by a return envelope 8 . The cooling liquid 9 is arranged in the cable 1 , evaporates after absorbing...

Abstract

The invention discloses an evaporative internal cooling multi-core cable circulation system, which comprises a cable containing cooling liquid and a cable cooling device, the cable cooling device includes an evaporation tank with a condensing part, one end of the cable It communicates with the evaporation tank through an evaporation connecting pipe, and the evaporation tank communicates with the other end of the cable through a return pipe. Through the application of the present invention, it can effectively help the cable to dissipate heat, thereby increasing the durability of the cable and improving the effective carrying capacity of the cable.

Description

technical field [0001] The invention relates to an evaporative internal cooling multi-core cable circulation system. Background technique [0002] With the expansion of city scale, the demand for high-capacity power supply mains is increasing day by day. Because the size of the conductivity depends on the following three elements: 1. The resistance of the conductor. 2. The allowable working temperature of the insulating material. 3. The strength of the cable's own heat dissipation capability. [0003] The impedance of the cable conductor depends not only on whether the material is aluminum or copper, but also on whether the cable is multi-core or single-core, and how it is laid. The allowable working temperature of the insulating material is high, of course the current carrying capacity of the cable will increase accordingly, but the resistance of the conductor will also increase with the increase of temperature (0.004Ω / 1℃), the line loss caused by the conductor, for larg...
