A kind of power cable that possesses the HF communication ability
Technical field
A kind of power cable that possesses the HF communication ability of the utility model belongs to the power cable technical field.
Background technology
Present power cable normally is encapsulated in the four-core copper cash in the cable, in order to satisfy the needs of communication, also can encapsulate several communication copper cash usually; The main distinction of communication copper cash and power copper cash is thickness, so power line provides energy thicker, the communication copper cash is then thinner; The power of main equipment is increasing at present, and all uses converter technology, causes power cable bigger to the interference ratio of telecommunication cable; Even power copper core is added shielding with the copper core of communicating by letter, effect is also very poor, its basic reason with the interference of frequency converter; The interference of large-scale power supply unit is mainly at low frequency end; And the copper core of communication usefulness also can only be in baseband transmission, and baseband transmission makes power line on mechanism, be difficult to remove to the interference of order wire just in low-frequency transmission.
The utility model content
A kind of power cable that possesses the HF communication ability of the utility model, technical problem to be solved provide a kind of a kind of power cable that possesses the HF communication ability that can eliminate power cable to the telecommunication cable interference.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of power cable that possesses the HF communication ability, comprise power copper core and coaxial cable, and power copper core and coaxial cable are encapsulated in the power cable.
The beneficial effect that the utility model compared with prior art has is: the utility model carries out communication through coaxial cable; Do not adopt baseband transmission during communication,, but move the frequency range of communication to high frequency through the mode of carrier wave adjustment just not in low-frequency transmission; So just having solved power line disturbs order wire; Increased reliability, also reduced of the requirement of integrated communicaton cable simultaneously, such as can not adding shielding etc. to power cable.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 is that power copper core, 2 is that coaxial cable, 3 is power cable.
Embodiment
As shown in Figure 1, a kind of power cable that possesses the HF communication ability of the utility model comprises power copper core 1 and coaxial cable 2, it is characterized in that: four power copper cores 1 and a coaxial cable 2 are encapsulated in the power cable 3.
The utility model carries out communication through coaxial cable 2; Do not adopt baseband transmission during communication,, but move the frequency range of communication to high frequency through the mode of carrier wave adjustment just not in low-frequency transmission; So just having solved power line disturbs order wire; Increased reliability, also reduced of the requirement of integrated communicaton cable simultaneously, such as can not adding shielding etc. to power cable.
Above-mentioned power copper core 1 belongs to prior art with coaxial cable 2.
Combine accompanying drawing that the embodiment of the utility model has been done detailed description above; But the utility model is not limited to the foregoing description; In the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from the utility model aim, make various variations.For example, the quantity of the power copper core 1 in the utility model can be confirmed its quantity according to the needs of reality.
