Self-cooling cable and cooling method thereof

Abstract

The invention discloses a self-cooling cable and a cooling method thereof. The self-cooling cable can realize self-cooling. The cable comprises a plurality of cable cores with insulation layers, wherein the insulation layers are wrapped with wrapping belt layers and external sheath layers, hollow ventilation layers for heat dissipation are arranged in the cable, the hollow ventilation layers are arranged in the wrapping belt layers, through holes are formed in the cable at intervals, and the through holes penetrate through the wrapping belt layers and the external sheath layers from the hollow ventilation layers, therefore, heat dissipation of the cable is realized by using the through holes. The cable disclosed by the invention further comprises a PLC (programmable logic controller), a temperature and water amount sensor and a sliding block for blocking small holes to be waterproof, thereby alarming when the temperature is too high, realizing automatic control of the sliding block to block the through holes in rainy days, and preventing rainwater from entering the cable and destructing the cable. The self-cooling cable disclosed by the invention has a simple structure, is easy to implement and can further realize fully automated control.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a self-cooling cable and a cooling method thereof. Background technique [0002] In summer, the outdoor temperature is too high, and summer is the peak of electricity consumption, and the cable load is too large. With the continuous increase of electrical equipment in the line, the current that the cable bears is also increasing. With the passage of time, the cable has aging phenomenon, and its carrying capacity will also be reduced to varying degrees. Once the current exceeds the rated carrying capacity, the cable will heat up. After reaching a certain temperature, the cable will break down and burn out. In severe cases, it will cause a fire. The spontaneous combustion of the cable is very dangerous, and it is difficult to extinguish the fire. In view of the fact that the fire cable has electricity, it cannot be extinguished with water. In addition, if there are flam...

Problems solved by technology

[0002] In summer, the outdoor temperature is too high, and summer is the peak of electricity consumption, and the cable load is too large. With the continuous increase of electrical equipment in the line, the current that the cable bears is also increasing. With the passage of time, the cable has aging phenomenon, and its carrying capacity will also be reduced to varying degrees. Once the current exceeds the rated carrying capacity, the cable will heat up. After reaching a certain temperature, the cable will break down and burn out. In severe cases, it will cause a fire. Spontaneous combustion of cables is very dangerous, and it is difficult to extinguish the fire

In view of the fact that the fire cable has electricity, it cannot be extinguished with water, and if there are flammable materials around, or other cables are ignited, causing the fire to burn to the building, it is easy to cause a fire situation that is difficult to control

Not only does it delay people's electricity consumption time in high temperature days, but it can even endanger lives. Therefore, how to cool down high-altitude cables is a very important issue
