Description
Technical field
The utility model relates to a kind of carrier signal coupling device of joint line carrier networking communication, especially refers to the carrier signal coupling device of the joint line carrier networking communication of " overhead wire-cable-aerial line ".
Background technology
The medium voltage power line carrier communication is by the electric power networks of power supply, carry out transfer of data with the cable resource, so no longer need to invest in the wireless system for transmitting data that lays new traffic cable or costliness, do not pay the expense that connects yet, therefore, can become one of the preferred manner of urban cells power distribution automation communication mode.
At present, the medium-voltage distribution network mainly is divided into K type (switchyard), P type (ring network structure), three kinds on W type (open air).Wherein, at radial pattern K type distribution net work structure,, study comparative maturity at present based on the pure cable shield carrier communication of pouring-in coupled modes; Screen carrier communication at ring network structure P type distribution net work structure, though some application are arranged, but, joint line especially refers to " overhead wire-cable-aerial line ", that is: line powering, be subjected to electric two ends to adopt overhead distribution line, feeder ear send by overhead distribution line, this joint line framework of power supply destination is delivered at last by cable (comprising repeatedly cable-aerial) in the centre by overhead distribution line, its carrier networking communication difficulty is bigger.Therefore, the carrier signal of the carrier networking communication of this joint line coupling still needs to solve with the employing effective and efficient manner, so, and one of content that the applicant endeavours to study that Here it is.
The utility model content
The purpose of this utility model is to provide a kind of carrier signal coupling device of joint line carrier networking communication, to be suitable for the carrier networking communication of " overhead wire-cable-aerial line " joint line.
The carrier signal coupling device of a kind of joint line carrier networking communication provided by the utility model, be used for joint line by overhead wire-the cable-aerial line is formed, it is characterized in that: comprise two coupling capacitances, two filter joints and two power line data transmission devices, wherein: with any one end that is connected to a coupling capacitance in the distribution wire three-phase of joint line feeder ear, this coupling capacitance other end connects the source class of a filter joint, the secondary power line data transmission device of receiving in succession of this filter joint; With any one end that is connected to another coupling capacitance in the distribution wire three-phase of joint line receiving end, this coupling capacitance other end is connected to another filter joint source class, secondary another power line data transmission device of receiving in succession of this filter joint.
Owing to adopted above-mentioned technical solution, solved problem for the carrier networking communication of the joint line of " overhead wire-cable-aerial line " class
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model, that is: the carrier signal coupling device of a kind of joint line carrier networking communication is used for the joint line be made up of overhead wire 4-cable 5-overhead wire 4, comprises two coupling capacitances, two filter joints and two power line data transmission devices.
Can feeder ear select 10kV or 35kV distribution wire A, B, C mutually in any phase (selecting the B phase usually), be connected to coupling capacitance 1 one ends, this coupling capacitance 1 other end access node closes filter 2 source class, the secondary high frequency cable of receiving power line data transmission device 3 in succession of filter joint 2.Equally, at receiving end, also select 10kV or 35kV distribution wire A, B, C mutually in any phase (selecting the B phase usually), be connected to coupling capacitance 1 ' one end, coupling capacitance 1 ' other end access node closes filter 2 ' source class, the secondary high frequency cable of receiving power line data transmission device 3 ' in succession of filter joint 2 '.Finish after this connection, feeder ear and receiving end just can be realized the point-to-point carrier communication of joint line.
Owing to power supply, be subjected to electric two ends to adopt overhead distribution line, carrier signal must be coupled on the built on stilts distribution line, could realize the transmission of carrier signal, and therefore, this kind joint line generally adopts capacitive coupling.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection range of the present utility model.
