The higher coverage rate of distribution site communication may be implemented in wireless important supplement.Medium-voltage carrier coupler is that 10kV power lines carry
The important component of communication techniques, the quality of Performance And Reliability have the overall effect of power line carrier communication
Conclusive influence.And many medium-voltage carrier coupler structures domestic at present are complicated, installation needs professional person on the scene, very
It is unfavorable for the extensive use of 10kV power-line carrier communications.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of medium-voltage carrier coupler.

Believe higher coverage rate, and the medium-voltage carrier coupler structure is simple, installation is easy, and is conducive to 10kV power line carrier communication skills
The extensive use of art.
Description of the drawings
It, below will be to needed in embodiment description in order to illustrate more clearly of the technical solution of the utility model
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only one embodiment of the utility model, for
For those of ordinary skill in the art, without creative efforts, other are can also be obtained according to these attached drawings
Attached drawing.
Fig. 1 is a kind of structure diagram of medium-voltage carrier coupler of the utility model.
Specific implementation mode
With reference to the attached drawing in the utility model embodiment, to this implement it is novel in technical solution carry out it is clear, complete
Site preparation describes, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.
