Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of technical solutions of the utility model is described in detail.Following example are only
For the technical solution of the utility model is clearly described, therefore it is only used as example, and this practicality can not be limited with this
Novel protection domain.
It should be noted that except as otherwise noted, technical term used in this application or scientific terminology should be this reality
The ordinary meaning understood with novel one of ordinary skill in the art.
As shown in Figure 1 and Figure 2, the overhead cable apparatus that the present embodiment provides, including: some cable cores 1, super-hydrophobic layer 2, guarantor
Sheath 3, heating wire 4, temperature sensor 5, switch 6 and power module 7；Cable core 1 includes the conductor layer 11 arranged from inside to outside, leads
Body screen layer 12, insulating barrier 13；It is outside that protection set 3 is wrapped in cable core 1, and it is outside that super-hydrophobic layer 2 is wrapped in protection set 3；Heating wire 4
It is arranged at the inside of protection set 3；Power module 7 is connected with heating wire 4 by switch 6, and temperature sensor 5 is connected with switch 6；
Temperature sensor 5 is for monitoring the temperature around cable core 1, if temperature is less than threshold value, controls switch 6 conducting.
Monitoring the temperature around cable core 1 by temperature sensor 5, when temperature is less than the low temperature threshold set, temperature passes
Sensor 5 controls switch 6 conducting, gives electric cable heating after heating wire 4 energising.Temperature sensor 5 is used to monitor, it is achieved automatically to give cable
Heating, to remove accumulated snow on cable, ice sheet, frost, alleviates cable and bears a heavy burden, it is ensured that the safety of cable power transmission.
Super-hydrophobic layer 2 can reduce adhesion and the flow resistance of solid-liquid surface, makes sleet be difficult to stick to cable surface,
Prevent rainwater from resting on power transmission line surface and form the situation generation frozen.Substantially any liquid is all had the highest by super-hydrophobic layer 2
